- Ben 10: "what if... the Omnitrix got damaged and exploded near Gwen and Max" (any time in 2005 series)

-old version:

the Omnitrix exploding caused its tech, energy and D.N.A to fuse into Ben, Gwen and Max, alerting Azmuth in the process so he would come to help/save them.

Ben's arm is destroyed but he becomes fused with the Omnitrix, his arm becomes pure energy and gains the use of all the Omnitrix functions including the alien D.N.A it holds, no longer needing to fully transform into the alien to use their abilities, along with having cyber enhancements implanted into him by Azmuth.

Gwen's Anodite D.N.A if forcibly awakened from the tech/energies infused into her and she becomes infused with the D.N.A of a Galvan (Grey Matter), a Galvanic Mechamorph (Upgrade) and a Ectonurite (Ghostfreak), increasing her intelligence and learning abilities greatly along with tech manipulation and ghostly powers, she becomes a master of both mystical and technological aspects.

Max was not as lucky, his limbs and aged old body was very damaged so he had to have half his body replaced with tech, but he did gain the D.N.A of a Arburian Pelarota (Cannonbolt), a Florauna (Wildvine), a Lepidopterran (Stinkfly), a Loboan (Blitzwolfer), a Opticoid (Eye Guy) and a Piscciss Volann (Ripjaws), turning him into the ultimate hunter cyborg that can hunt down anything anywhere, though he does tend to relax and use his abilities for his cooking.

-new version:

Ben was angry, sad, in despair and so other many emotions that he couldn’t think. Feedback, one of HIS transformations, was gone, destroyed right before him, he felt like a part of himself was ripped away from him, this pain, no other villain had made him feel this, not even Vilgax, he hated it, his blood boiled at it, so, enraged, he overloads his Omnitrix and plunges it deep into the monster Malware, overloading him and causing him to explode, sending a wave of energy that knocked them all back.

Max and Gwen got up and quickly ran to Ben's side as he sat up, they tried to comfort him but a crackling of energy and the Omnitrix shaking got their attention, Azmuth shouted for them to run but it was too late, the watch cracked down the middle and then exploded, energy burst out in a flash of light and the world shook.

Azmuth recovered and was quick to run to the crater that was created, he found the family spread apart and with grave injuries or mutations to their forms including Ben missing his left arm, he was quick to have them teleported to his home world and put into medical care to save their lives.

Gwen awoke to Max and was shocked at his new appearance, he still looked somewhat like himself but he was now a little more built-in muscle and leaner, his lower jaw was now thicker and sharp teeth poked out, he had Ripjaws angler upon his forehead, orange fur covering his cheeks going down past his neck, showing Wildmutt’s gill sensors, and covering his arms, his hands and feet now had scaly palms and webbing between their digits, long curved black claws from Blitzwolfer as well as the tail, upon his biceps and palms of his hands where a pair large eyes from Eye Guy, along his chest, forearms and calf’s was Cannonbolt’s armour plating with some small vines and plants around the edge from Wildvine, and upon his back was two large pieces of Cannonbolt’s armour that look like a bug shell with Stinkfly's wings tucked underneath, he had patches of metal in places that was only slightly discoloured from the places they blended in with.

Gwen got up and asked what was going on and why it seemed Max was genetically infused with Arburian Pelarota, Florauna,  Lepidopterran, Loboan, Opticoid and Piscciss Volann D.N.A sequences, she paused at what she just said and how she knows what she said, then realises the Omnitrix explosion must have infused them with traces of the alien D.N.A within altering and or enhancing them, Max said she was right and pointed to a mirror for her to see her own changes.

While not as bad as his, they were clear, she now had a soft grey skin tone, black crack lines running along her body, like Ghostfreak, connecting to her left eye making her look like she had eyeliner, her right eye was of the same style only with a glowing pink that went in a straight line to the side and down her right cheek and neck where it spread out across the rest of the body, her hands and feet where coloured bitch black with black patches located down her sides and covering her back.

Instinctively she made the black patches extend out and or separate from her body, creating either extra limbs or floating orbs with holo-pads displaying vast amounts of data that she understood.

After seeing and concluding she was infused with Galvan, Galvanic Mechamorph and Ectonurite D.N.A she realised that Ben was not with them and asked where he was, Max explained that he was still in surgery and showed her the way to a viewing room, showing them Ben laying down with his waist covered and a many number of Galvans working on him, Azmuth was there focusing on Ben's left shoulder, attaching advance technology and giving orders to the others.

Max explained that the watch exploding had taken his arm and infused Ben with all its energy and D.N.A, effectively making him a living Omnitrix, but he needed time to heal both physically and mentally.

Some time passed with Ben coming in and out of it as he was fixed up and healed over several days, the kid's parents were brought to the planet and told of everything that had been happening, while upset at the secrets they were far happier for them all to be alive, if somewhat different, Ben was very quiet which saddened them, it was Gwen and Azmuth that helped him pep up, Azmuth telling him of how he had used the watch in ways he never thought of before and how winning wasn’t everything, that this loss and injuries where just a new lesson for him to learn from, Gwen spoke of how determined he had been with and without the watch, how he had saved so many before and that he was a true hero, that it was okay to cry, and he did while she hugged him.

Time passed with Ben now back on his feet and better, he now had a glowing energy arm made from the energy of the Omnitrix that was now within him, he was a little faster and stronger than he was before along with some cybernetic implants that also helped with collecting new D.N.A samples and looking up the alien's species, he could even use the alien's powers without transforming now.

Gwen's parents told her of her Grandmother being alien and her powers being linked to that, they even had her visit, Verdona was happy to know her granddaughter could use mana but was upset at the event that changed her form as it meant she couldn’t fully transform into an Anodite, but she was still happy to teach her all she knew along with Azmuth teach her science and tech of his people as she was now an honorary Galvan.

Max had been getting used to his new form and abilities, finding they opened up the doors to his missed youth of speed, strength and agility, they even helped enhance his cooking skills by being able to hunt and grow what he needed.

A year passed with them training in their new abilities before missing home and returning, using holographic tech to hide their new looks so they could blend in, they only took them off when the events of Alien force came to start.

character descriptions:

Name: Benjamin "Ben" Kirby Tennyson

Age: 11 (post-recovery)

Race/Species: Human-Omnitrix Hybrid

Physical Appearance: Ben stands at the same wiry 4'8" as before the accident, but now moves with a subtle, humming energy that makes dust swirl near his sneakers. His signature white T-shirt and green jacket remain, though both fabrics shimmer with hexagonal energy-dampening weave—Galvan tech woven into every thread. The jacket sleeve hangs empty over his left side, but when active, his new arm manifests as a crackling construct of emerald Omnitrix energy, shaped like translucent muscle and bone with the iconic dial pattern glowing where his wrist should be. At rest, it retreats into a faint green aura around the shoulder stump.

Cybernetics gleam along his right temple—a lattice of silver circuitry tracing up to his ear—and twin ports glow beside his spine where Azmuth embedded interface nodes. His eyes hold flecks of alien constellations: pupils shift minutely between reptilian slits and compound hexagons when stressed. Most striking is the Omnitrix symbol now burned into his chest—no longer a device, but a living brand pulsing soft green light that leaks through his shirt. When using alien powers, veins flare with corresponding colors (Heatblast’s orange when pyrokinesis ignites, XLR8’s blue when super-speeding).

Background: The explosion wasn’t just Feedback’s death—it was the moment Ben’s childhood shattered. As Malware detonated, Ben’s scream fused with the Omnitrix’s rupture, grafting its core to his nervous system. Azmuth later explained the impossible: Ben’s DNA had become a biological failsafe, absorbing the watch’s matrix to save his life at the cost of his arm. For weeks in Galvan ICU, he drifted between nightmares of disintegrating aliens and waking to phantom limb pain crackling with unstable energy.

Recovery was a silent war. Gwen’s new techno-mystic abilities let her stabilize his energy surges, while Max’s hybrid form carried him through rehab sessions disguised as "stealth training." Azmuth’s cybernetic grafts did more than replace bone—they turned Ben into a living archive. Every implant whispers alien languages; his dreams replay genetic memories of Vulpimancer hunts and Tetramand wars. The hardest lesson? Control. Early attempts to summon Four Arms’ strength shattered his bedroom wall. Channeling Ghostfreak’s intangibility left him half-fused with the couch. But when Charmcaster attacked during his first week home, Ben instinctively formed a Diamondhead crystal shield over his cousin—without transforming. That victory, small and desperate, reignited his spark.

Personality: Ben’s trademark bravado remains, but it’s quieter now—tempered by phantom pains and the weight of being a living weapon. He cracks fewer jokes mid-fight, instead analyzing threats with unnerving focus as alien knowledge surfaces ("Opticoid weak points: lateral eyelids"). Yet when a civilian’s in danger? That’s when the old Ben surges back—grinning fiercely as he body-checks a rogue Null Guardian with Upgrade-enhanced strength, shouting "Still got this!" through gritted teeth.

He’s developed subtle tics: tracing Omnitrix symbols on tabletops when anxious, or unconsciously mimicking Grey Matter’s rapid-blinking during tests. Food tastes "wrong" unless Max cooks it (his grandfather’s new Ripjaws-enhanced umami sense balances Ben’s altered palate). Surprisingly, he loves his energy arm—customizing its density to pitch baseballs as XLR8 or high-five Gwen without burning her. "Super-ultra-mega upgrades," he calls it, though Azmuth hears him whispering thanks to the empty space where Feedback’s D.N.A hums.

Deep down, the fusion amplified his core: protectiveness. When a toddler nearly drowned last summer, Ben didn’t think—he became Ripjaws’ gills *and* Jetray’s thrusters simultaneously, water roaring from his energy hand as he dove. Afterward, hiding his glowing veins under holograms, he muttered, "Would’ve done it with one arm anyway." The watch is gone. Ben Tennyson is the Omnitrix now—and he’s just getting started.

Name: Gwen Tennyson

Age: 11 (post-accident)

Race/Species: Human-Anodite hybrid with Galvan/Galvanic Mechamorph/Ectonurite DNA infusion

Physical Appearance Gwen’s form is a haunting fusion of magic and machine. Her skin has shifted to a soft, luminous gray—like moonlit marble—with intricate black cracks tracing across her limbs and torso like shattered porcelain artfully repaired. These fractures converge dramatically around her left eye, forming natural, elegant "eyeliner" patterns that deepen when she channels energy. Her right eye burns with concentrated Anodite power: a vivid magenta stripe slicing from pupil to temple, fracturing into delicate glowing veins that cascade down her neck and collarbone. The light pulses rhythmically, syncing with her heartbeat when she accesses mana.

Her hands and feet are obsidian-black, ending in subtly tapered fingers that seem to drink surrounding light. Along her ribs, spine, and shoulders, inky Galvanic Mechamorph patches cling like liquid shadow—smooth as polished onyx when dormant. When activated, they peel away into floating tech-constructs: holographic interfaces shimmering with pink-and-green data streams, or slender tendrils tipped with data-ports that crackle with arcane energy. Her auburn hair now streaks with metallic silver, often lifting in an unseen breeze as stray pink sparks dance through the strands. She moves with uncanny silence, hovering centimeters above the ground in a permanent low-float—a subconscious echo of Ectonurite intangibility—while a Raven-style cloak billows around her, its edges dissolving into holographic mana-dust.

Background The Omnitrix’s catastrophic explosion during Ben’s confrontation with Malware didn’t just scar Gwen—it rewrote her existence. As Azmuth later explained, the blast force-awakened her latent Anodite mana while violently splicing her DNA with fragmented Omnitrix samples. Strands of Galvan intellect, Galvanic Mechamorph adaptability, and Ectonurite phasing fused into her cellular structure during emergency surgery on Galvan Prime. For weeks, she woke to overlapping realities: understanding quantum mechanics as instinctively as breathing, while ghostly whispers of Ectonurite consciousness haunted her dreams.

Her recovery became a dual education. By day, Azmuth taught her to command her mechanized abilities—nanites assembling drones from scrap metal or decrypting alien databases in seconds. By night, her grandmother Verdona guided her through mana channels now tangled with foreign energies. The fusion had a cost: Gwen could no longer fully ascend to Anodite form, her body anchored by synthetic elements. Yet this limitation birthed innovation. She learned to weave spells through Mechamorph tech, creating holographic runes that stored mana like batteries, or phasing through walls while cloaked in invisibility—a seamless blend of ghostly essence and hardlight projection. When Ben returned, fragile but resolute, Gwen became his anchor—her calm logic tempering his grief, her newfound prowess a silent vow: *We adapt*.

Personality Gwen’s mind now operates with terrifying efficiency. Galvan DNA sharpened her intellect into a surgical instrument—she absorbs textbooks in minutes, solves fractal equations mid-conversation, and critiques Azmuth’s theorems with dry, razor-sharp wit. Yet this brilliance is tempered by Ectonurite-induced hypersensitivity. She perceives emotions as tangible auras: Ben’s guilt radiates jagged crimson waves; Kevin’s sarcasm flickers like neon static. To cope, she retreats into ritual—organizing spellbooks by chromatic resonance or calibrating holograms into geometric mandalas when overwhelmed.

Beneath the logic lies Anodite passion, amplified by trauma. She defends her family with ferocious creativity, merging tech and magic in startling ways: conjuring ectoplasmic shields layered with Mechamorph reinforcement, or transmuting rubble into Galvan-derived energy nets. Her humor remains, now laced with galactic physics puns ("That plan had more holes than a quantum foam!") or ghost-themed wordplay ("Talk about *dead* air!"). Yet when alone, she traces the cracks on her gray skin, wondering if she’s still human or a patchwork of salvaged wonders. This duality defines her: a scholar who speaks in binary yet cries pink mana-tears; a girl who bends reality but still blushes when Ben calls her "Doofus." Her greatest strength? Embracing the fusion—wearing her cloak like a banner, turning alien fragments into art, and whispering to the scared girl in the mirror: *"We’re not broken. We’re upgraded."*

Name: Maxwell "Max" Tennyson

Age: 72

Race/Species: Human-Alien Hybrid Cyborg

Physical Appearance: Max stands at a solid 6'2" with a frame that’s leaner and more muscular than before, yet retains the comforting bulk of a grandfather who’s seen decades of adventure. His face remains recognizably human—wrinkled at the corners of his eyes from years of laughter—but now sports subtle, wilder edges. Thick orange fur, soft as worn flannel, frames his jawline and spills down his neck like a lion’s ruff, tapering into Wildmutt’s gill-like sensors along his collarbone. His lower jaw has widened slightly, hinting at Blitzwolfer’s lupine strength, with sharp but neatly aligned teeth that peek out when he grins. Atop his forehead rests Ripjaws’ bioluminescent angler lure, pulsing a gentle amber when he’s alert.

His trademark red-and-white Hawaiian shirt stretches over Cannonbolt’s segmented armor plates embedded across his chest and forearms, edged with delicate Wildvine tendrils that sprout tiny, sweet-smelling blossoms. The armor continues down his calves, seamlessly blending into his skin like polished river stones. Four of Eye Guy’s iridescent orbs—two on each palm and bicep—glow with intelligent awareness, their pupils contracting in sync with his emotions. His hands and feet are scaled and webbed like Ripjaws’, ending in curved obsidian claws perfect for scaling cliffs or chopping vegetables. Hidden beneath his shirt, Stinkfly’s iridescent wings fold against his back, tucked under Cannonbolt’s domed shell plating that clicks softly when he moves. Minor cybernetics appear only as silver seams along his joints—subtle reinforcements for an aging body reborn.

Background: The Omnitrix explosion shattered Max’s ordinary retirement, fusing him with six alien species in a desperate bid for survival. Azmuth stabilized him, grafting cybernetics not as armor but as lifelines—reinforcing brittle bones and aging organs. During recovery on Galvan Prime, Max discovered his new biology wasn’t just practical; it was poetic. Cannonbolt’s plating shielded him while Wildvine’s flora wove through his garden, Ripjaws’ aquatic senses made fishing trips legendary, and Blitzwolfer’s reflexes turned campfire cooking into precision artistry. Stinkfly’s wings carried him over forests, and Eye Guy’s vision spotted ripe berries from miles away.

He spent a year mastering his body’s symphony, guided by Gwen’s newfound intellect and Ben’s resilient spirit. When the trio returned to Earth, Max’s RV became a mobile lab-kitchen hybrid. He’d hunt invasive species (culinary or alien) with predator’s grace, then simmer them into gumbo while holograms hid his form from prying eyes. By Alien Force’s dawn, he’d perfected "fusion foraging"—tracking threats using Loboan scent trails, then neutralizing them with Pelarota rolls or Opticoid blasts—all before lunch.

Personality: Max remains the soul of the team—a steady campfire in a storm. His humor is drier now, punctuated by a Blitzwolfer-esque chuckle that rumbles like distant thunder. He’s embraced his mutations not as flaws but as "upgrades": using Eye Guy’s peripheral vision to spot grandkids sneaking cookies, or Wildvine’s photosynthesis to bask contentedly in the sun. Though he moves with lethal efficiency when hunting, he’s disarmingly gentle—scaled hands carefully replanting uprooted saplings, claws retracting when ruffling Ben’s hair.

His quirks are endearingly practical. He absentmindedly grooms his orange fur while pondering, Cannonbolt’s plates clacking like teacups. When excited, his angler lure brightens, casting warm light on late-night stories. He’s developed a love for "extreme gardening," nurturing bioluminescent flowers that bloom under Ripjaws’ lure. And while he’ll grumble about "kids these days" (even as Gwen calculates warp trajectories), his eyes—all six of them—soften when teaching Ben to channel grief into strength. To him, the universe is still a backyard barbecue; he just needs bigger napkins now.

Chapter Text

- Ben 10: "what if... the 2nd Body Switch spell attempt went wrong" (Episode A Change of Face)

-old version:

When the spell is cast the Omnitrix energies cause the spell to go wrong, Gwen is placed back into her body, but Charmcaster and Ben instead of swapping bodies get fused together into a new person, which results in their minds/memories combining, this allows the new person, named Hope Tennyson, to know all about Charmcaster’s past, losing her father and home, needing to survive and trying to gain the power to take down Addwaitya.

After telling Gwen and Max they decide to help, Hope helps train Gwen in magic while also learning their own new powers of both alien and magic capabilities, years later with their friends, allies, including Hex and a few other former villains, and years of experience they enter Legerdomain, fighting against Addwaitya to reclaim The Realm of Magic.

-new version:

As the spell was cast and covered Ben, Gwen, and Charmcaster the magic energies reacted with the Omnitrix's own energy causing them both to become unstable and burst out of the watch, resulting in a small explosion of pink and green energy that blew Max onto his backside. A few minutes passed after the blast before Max got back up, he looked around for his grandkids, the smoke and dust making it hard to do so but he soon found Gwen who was sitting up and rubbing her head, he asked if she was herself again and she confirmed it when asked a question about her 8th birthday, the pair's attention was grabbed by the shadow of a rising figure nearby, they called out asking if it was Ben, the person said "yes.. no... I am but... I'm not? i... I don't know..." the figure walked out of the smoke and the pair were shocked at what they saw.

The figure had Charmcaster's body build but was slightly shorted, their hair flowed from a brown base to a silver-white mid-length down to the ends, their eye colour was a pink outer rim with green inner ring, two gold earrings on each ear along with purple lipstick, their clothes was a white tight shirt with swirling purple lines flowing up around the collar to the sleeves, an open magenta coat with black lines at the sleeve ends that flowed along the back of the arms to the collar and outer edges, purple form-fitting cargo pants with side pockets that smoothly transitioned into short heeled boots with black and white straps around them, a black belt with purple rounded buckle, a magical bag around their waist and on their left wrist was what looked like the Omnitrix only it was now smoother, almost like an armband, it's main colour was still black but now it had purple instead of green and had runic markings along its ends.

Gwen was shocked but seeing the watch she asked if it was Ben, the woman said she was but wasn't, that she was Ben and Charmcaster together, she had all their memories, she proved this by mentioning a few things from before their summer trip, but she was so confused on who she was, was she either Ben or Charmcaster or neither, Max calmly placed a hand on her shoulder and stated why can’t she be both, this had her smile but then tears started to fall, when asked what was wrong she said she knew why Charmcaster was trying to get power, it was to face a foe called Addwaitya.

The family sat down with some hot chocolate as the girl explained, she told them of where Charmcaster and Hex came from, another dimension, that their home was one of magic and crazy physics, that it was conquered by a giant turtle creature that got its hands on a powerful ruin stone and forced Charmcaster and her uncle to run from their home while her father gave his life for them to live, that all she wants was for Addwaitya to be defeated and maybe bring her father back, but she didn't believe in it as she knew the girl’s father wouldn't want the price to be paid for his return, when asked what the price was she said it was 600,000 souls which shocked them both for a few moments before continuing on.

After a bit more talking the girl, now named Hope Benjamin Tennyson, stated she wanted to at least help free Charmcaster's original home in her memory as she was a part of her, the others agreed and began making plans, they knew they couldn't do it right away, both because of Hope's new form and abilities needing to be trained, and for them to gather the tools and help to accomplish it, with their plans laid out they continued their summer vacation.

Time passed, Gwen was taught by Hope as they both learned and relearned magic together, the three of them having to tell the family about their adventures and what happened to Ben and her new form, along with Max's life as a plumber which resulted in both Gwen and Hope being told of their grandmother being alien and her powers being the main source of magic known as Mana, over time Hope took off the watch from a decline in bad guys but still kept making plans for their reclaiming of Legerdomain, she put it back on when the events of Alien Force happened and teaming up with Kevin, who was shocked over Ben's fusion with Charmcaster becoming Hope, after the events of Ultimate alien and with her new modified Magic infused Omnitrix the team and all their allies, including a calmed with aged Hex, and Plumbers made their move on Legerdomain, they battled Addwaitya and his army, using her magic and powered up alien transformations they were able to beat him and drain him of all his magical abilities.

With her old home now free and being claimed its mistress by magic itself, Hope had Hex placed as her regent to help rebuild the lands to what they once were for all, this was so she could continue keeping the galaxy safe on earth, with that done and new alliances forged Hope continued on her grand adventures into the Omniverse.

character descriptions:

Name: Hope Benjamin Tennyson

Age: Appears 17 (chronologically ages from fusion event)

Race/Species: Human-Magic Hybrid / Omnitrix-Bearer

Physical Appearance: Hope stands at 5'6" with a lithe, athletic frame that moves with eerie grace—a fusion of Ben’s loose-limbed energy and Charmcaster’s poised intensity. Her skin glows faintly with an opalescent sheen, like moonlight on water, where patches of Ben’s olive complexion blend seamlessly into Charmcaster’s alabaster tones. The most striking feature is her hair: thick, waist-length locks that start as Ben’s warm chestnut brown at the roots, shifting into iridescent silver-white halfway down, ending in tips that shimmer with trapped starlight.

Her eyes hold galaxies—a pink outer iris bleeding into a vibrant green inner ring, pupils sharp as fractured emeralds. Gold crescent-moon earrings dangle from each ear, humming with latent magic. She wears practical yet mystical attire: a white bodysuit with swirling purple energy patterns that pulse like living circuitry, a cropped magenta coat lined with black sigils that flutter without wind, and fitted violet cargo pants that taper into boots with heeled soles etched in protective runes. The Omnitrix, now a sleek armband fused to her left forearm, glows with amethyst light instead of green, its surface engraved with ancient runes that shift like liquid metal.

Background: Hope was born in a cataclysm of magic and alien tech during Charmcaster’s botched body-swap spell. When Omnitrix energies collided with Legerdomain’s magic, Ben and Charmcaster didn’t swap bodies—their souls merged, creating a new consciousness forged from Ben’s heroic drive and Charmcaster’s tragic desperation. In the smoke-filled aftermath, Max and Gwen found a trembling figure clutching a transformed Omnitrix, whispering fragmented memories of both lives: birthday parties with Grandpa Max, and the screams of her father sacrificing himself to Adwaita’s sorcery in Legerdomain.

Reclaiming Charmcaster’s stolen realm became Hope’s purpose. She trained Gwen in magic while mastering her own hybrid abilities—channeling mana through the Omnitrix to create techno-magical alien forms. Years later, leading allies including a redeemed Hex and Plumber forces, she stormed Adwaita’s fortress. In a crescendo of spellwork and alien power, she shattered his Soul Stone, freeing Legerdomain. Magic itself crowned her the realm’s guardian, but she entrusted its restoration to Hex, choosing to protect Earth with her team.

Personality: Hope radiates fierce compassion—a blend of Ben’s stubborn optimism and Charmcaster’s hardened wisdom. She jokes with Ben’s goofy grin but tempers it with Charmcaster’s sharp wit, often quipping about "magic being 90% dramatic flair" during battles. Though her fused form initially caused dysphoria (flinching at reflections, hiding her mismatched hands), she embraced it as strength: "This body? It’s a treaty. Proof enemies can become allies."

Her quirks reveal the fusion’s depth: she absentmindedly sketches Plumber tech upgrades in spellbooks, eats peanut butter-and-honey sandwiches with Hex’s tea ceremony precision, and speaks to the Omnitrix like a friend. When angered, her magic flares pink-green—a warning that carries Ben’s protective fury and Charmcaster’s cold vengeance. Yet she cries over lost souls in Legerdomain’s ruins, whispering, "No one deserves to be a pawn." Her heroism isn’t borrowed; it’s earned, a bridge between two broken worlds she refuses to let collapse.

Omnitrix Design Details: The device wraps around her forearm like living armor—obsidian-black with veins of petrified wood and polished stone. Gold and silver alloys form intricate Celtic-knot patterns, while floating holographic runes hover above engraved symbols. Crystalline panels along its length swirl with captured Legerdomain energies: nebulas of violet and emerald that pulse in time with her heartbeat. The dial remains, but now glows with a three-dimensional mana-glyph interface, responding to thought and touch alike.

- Kim Possible: "what if... Shego's plasma powers had side effects" (any time in the series)

-old version:

Kim has been showing signs of being extremely ill, when Wade scanned her he found traces of Shego's plasma energy inside her, from their constant battles and getting hit by the blasts, which is killing Kim like radiation poisoning, they try multiple ways to help her but all come up short, they contact Shego, informing her of what is happening and out of respect for Kim's skill's in fighting her she helps them.

By transferring some of her D.N.A along with some cyber implants to replace the damaged tissue in her body, Kim gains the same powers as Shego along with cyber enhancements, making her a plasma-wielding cyborg, Shego stays around to help teach Kim how to use her powers, because of this the two get close and Shego becomes neutral instead of evil, working with team Possible on occasion.

-new version:

Kim was tired, now this wouldn't be odd given her active life, but for a while now she had been feeling really slow and heavy, like she was moving through thick mud, which is why after just an average day of school she was sitting back on the couch like she had just taken 3 missions back to back, she only moved when her twin brothers came running pass and grabbing her Kimmunicator, she jumped up and ran around the room trying to get it back, but that's when she suddenly went dizzy and weak, she stumbled for a few feet, making her brothers stop and watch as she fell down and bounced off the coffee table, the boys cried out and rushed to her side, seeing her unconscious and sweating they shouted for their parents, who came rushing in, Ann went into doctor mode and check her daughter out as the twins explained what happened, she had James call an ambulance while the twins called Wade.

Kim was soon rushed to the hospital and checked out, her vitals were weak, when she woke up hours later and asked what happened she explained she had been feeling weak for a while, thinking she was just stressed, but Ann and Wade said it wasn't, her body was weakening and Wade performed scans, it seems she was exposed to high levels of energy that have seeped into her body and were causing her body to break down, and that is they couldn't find a way of stopping it...she would die.

Kim was kept in the hospital for days, constantly monitored, Wade came in person to help run scans along with Global Justice coming in to help, there were points when her body spasmed and needed to be rushed into operations with Ann helping out, parts of her body had been so damaged and infected by the energy that they needed to be removed. Ron and Rufus came by as often as they could to try and keep her spirits up while everyone tried to figure out how to cure her.

Wade finally found a match to the energy that was inside Kim, it was the same as Shego's, he, along with others, theorized that Kim's constant exposure and hits from Shego's plasma blasts must have left so much residue that Kim's body didn't have time to naturally filter it out so it built up and was now affecting her. the only way to find a cure and save Kim was to get Shego and perform scans and tests to try and make Kim immune to the energy, Ron was quick to go along with Betty Director and Will Du.

They were able to locate Drakken's lair and made their entrance, after beating his henchmen and stopping him from trying to launch a satellite into space they told both him and Shego that they weren't there for his evil plan but for Shego, she wanted to know what they wanted and they explained what was happening to Kim, Shego wasn't too sure about helping but Ron asked if there really wasn't any form of respect she had for Kim and their fights, that she would really let something like this take her out, Shego hated how much the idiot made sense and decided to help if only so she can beat Princess herself.

After returning they got to work, many tests were performed on them both, and tests with their blood, they found that Shego had a natural resistance to her energy because it came with her powers, that it was infused with her D.N.A and the only way to help Kim was to infuse her with Shego's D.N.A to give her the same resistance, but this was taking a lot of time that they didn't have, Kim needed to have more operations and machines to stabilize her, for something this complex they had to call in others to help, DNAmy and the Senior's, Amy for her D.N.A mastery and the Senior's for their resources.

Amy helped because Kim was a fellow Cuddle Buddy lover and Senior helped because he respected the teen hero, they soon had all the tools and equipment needed for what they needed to do next, for they needed to not only infuse her with Shego's D.N.A but also remove the deeply infected areas and replace them with advance cybernetics, such tech being created by the hands of Wade, James and the twins of the days of waiting for any sign of a cure, knowing Kim wouldn't come out of this unscathed given the operations she had already gone through.

It was the most complex and tasking operation to date, the careful removal of infected muscle, parts of organs, and replacement of said areas, while also constantly infusing and injecting new strands of Shego's active D.N.A into the right parts, all took twenty-four straight hours. in the end they needed to remove 39% of Kim's flesh and replace it, from her left eye, her left hand, back of her right forearm, part of her mid-upper back, right section of her waist, left outer thigh, her kneecaps and the bottom half's of both feet. It was hard but they did it, Kim was saved.

It took a few days for her body to settle and Kim to wake up, she was taken aback by her new additions but was thankful so many fought to save her, she was especially surprised by some of her villains helping out, Junior brought her a large vase of flowers and just said life would be boring without her with a slight smile that she returned, Shego said she better not get used to it and that she will be getting her butt whooped by her in the upcoming training she will get when back on her feet, when asked what she meant Shego grabbed her hand and forced her energy into her and suddenly orange flames like Shego's own burst into the palm of the teen's hand, Shego explained that with her D.N.A she has powers like her own and will need training to get them down, Wade also stated with her new cybernetics she can have gadgets built in to help her with missions, further enhancing her capabilities.

Time passed with healing and training as Shego stated, said woman becoming more of a mentor than a villain over time, soon Kim had learned enough for them to part ways, and with Shego stating she better give her a good fight next time they face off, Kim promised her and with that, they went to more rivals than foes.

The villains weren't ready for a cybernetic superpowered Kim Possible and got taken down easier than ever, which led to them powering themselves up with either tech, magic, or altering their own D.N.A. to try and stand a chance of winning, which never worked.

Overall, things went on as normal for all.

they land and follow the Force as it leads them towards floating and rotating landscapes, walking up a large hill they are surprised to find Ahsoka meditating at the centre of the Force presence, after some talking she explained that after leaving she felt empty and without purpose in her life, that is when the Force, the TRUE Force contacted her, leading her here where she learnt that the Force is neither light nor dark but what the user uses it for that defines it, she then saw the far future and was given the choice of what to do, she chose to change it, so using her new abilities she reached out and enhanced Palpatine's rage so he would reveal his true self, that being Darth Sidious.

she explains that if not done right he will continue to live after death and posses someone else to be his new body, which was what he was planning for Anakin, to have him kill him so he could posses him and become all powerful, this was a shock to Anakin as he felt deeply betrayed, when asked how they could best him she said the only way was for Anakin to learn to connect with all those the force touches and redirect Palpatine's own power against him so he would destroy his own spirit forever.

time passes with training and the removal of mind chips from the clones so the command codes would not force them to kill the Jedi or any others, soon Sidious attacks with his forces, it is an all out fight between their forces, Anakin and Ahsoka battle Sidious, pushing against the odds, they finally are able to redirect his power back at him by connecting to all in the universe through the Force and destroy him forever along with the Sith home world Exegol as he had drawn power from it and those upon it.

after the war ends the Jedi order rebuilds itself with Ahsoka and Anakin's help so they didnt have to cut themselves off from their emotions and connections anymore, leading to everlasting peace in the universe.

character descriptions:

Name: Gwendolyn "Gwen" Tennyson

Age: 10

Race/Species: Human-Monster Hybrid

Physical Appearance Gwen’s form is an eerie yet elegant fusion of Halloween Town’s charm and her own heroic spirit. Her skin is now a pallid, stitch-sewn canvas—like weathered parchment held together by thick, black surgical threads tracing her limbs and torso. These stitches glow faintly with residual magic, pulsing like embers when she channels her powers. Her hair cascades past her shoulders in vibrant crimson waves, ending in luminescent pink-violet flames that flicker without heat, casting soft shadows around her. The fiery tips dance like will-o'-wisps, reacting to her emotions—brightening when she’s determined or amused.

She wears bandages not as restraints but as garments: ivory wrappings coil around her body like a living mummy’s dress, forming a sleeveless tunic that flares at her hips. The fabric moves independently, often lifting like spectral ribbons or tightening into protective layers. Her legs remain visible beneath knee-length wrappings, ending in mismatched boots—one stitched leather, the other bandage-wrapped—hinting at Frankenstein’s cobbled craftsmanship. Her eyes retain their original bright green hue but now glow softly in dim light, framed by dark lashes and subtle charcoal smudges reminiscent of a witch’s cunning gaze. No armor bulks her silhouette; instead, her form flows with nimble grace, embodying Sally’s delicate patchwork and Jack’s lanky poise.

Background Gwen’s transformation began during a reckless teleportation spell experiment in her bedroom. Instead of shifting a foot sideways, she tore through realities—a chaotic journey that reshaped her body with Halloween Town’s monstrous energies. Stranded in a gothic graveyard beneath a spiraling hill, she was discovered by Jack Skellington and Sally, who guided her to Dr. Finkelstein. The doctor confirmed her human essence had merged irreversibly with Halloween Town’s magic, transforming her into a unique hybrid.

Through Finkelstein’s portal-window device, Gwen contacted her family. Azmuth, intrigued by her stable mutation, engineered a two-way portal but deemed reversal impossible—the fusion was too deeply woven into her cellular structure. Embracing her new reality, Gwen trained under Sally’s guidance, mastering limb detachment and telekinetic bandage control. She later traveled to Ben 10’s Anur System (though unrelated to Halloween Town), becoming a bridge between human and monster cultures while aiding Plumbers missions with her refined magic and combat skills.

Personality Gwen remains fiercely compassionate and intellectually curious, her core unchanged despite monstrous trappings. She greets her appearance with wry humor—calling her flaming hair a "built-in nightlight" and joking about misplaced limbs during training. Her empathy shines brightest when comforting others; she’ll detach a hand to pat a crying child’s shoulder or weave bandages into makeshift blankets for refugees. Yet she’s no naive idealist: her magic now carries eerie practicality, like conjuring violet-energy shields shaped like pumpkin glyphs or ensnaring foes with sentient wrappings.

Her quirks reflect her duality: she collects spellbooks *and* Halloween Town trinkets (like "souvenir" tombstone rubbings), debates quantum physics with Finkelstein, and insists on "monster-friendly" upgrades for Plumber tech. When villains mock her form, she retorts with witchy wit—"At least my stitches hold my brains *in*"—proving heroism isn’t skin-deep. Though powerful, she avoids arrogance, often retreating to Halloween Town’s moonlit hills to stargaze with Sally, reminding herself that fearlessness means embracing every stitch. -

Image Prompt Description > *Gwen stands confidently in a moonlit graveyard, her fiery hair illuminating ancient tombstones. She wears a bandage-dress that flows like liquid cloth, one arm detached and hovering beside her as ribbons of wrappings spiral playfully around her legs. Glowing stitches trace her visible skin, and her green eyes shine with warmth against her pale face. Behind her, a twisted hill curls toward a pumpkin-dotted sky. Style: Tim Burton’s whimsical gothic (The Nightmare Before Christmas) blended with Monster High’s fashion-forward edge. No armor; heroic poise intact.*

with her new form Betty and Hulk took down Abomination before fleeing from the city, later on Betty learned how to switch between her forms so she could go out without others knowing, Bruce came to terms with the Hulk but offered to find a cure for Betty, which she turned down, saying this not only helped her be closer to Bruce but also in defending herself, she stayed with Bruce helping out in saving lives until they were brought into the avengers.

- Ben 10: "what if... another human was experimented on with the Nemetrix" (any time after the Ben 10 original series) 

Dr Psychobos and Malware decided they needed another test subject for the Nemetrix that wasn't exposed to the unique energies of the Null Void like Phil was in order to see the different effects, so they chose a young 17-year-old human female of earth, after abducting her and implanting the device to her the effect was almost instant, arc or energy burst from both it and her and she began shifting between predator forms and human form at random causing her to break free, during her rampage she hit energy containers causing large amounts of energy to go through her and blast the Nemetrix off of her, but she continued to shift forms.

The villains tried to detain her but she crashed into a teleporter and the energies coming off of her activated it and sent her randomly teleporting away, during her wild transportation Paradox appeared and directed her path to Galvan Prime, no more than moments after landing and continuing a rampage in the nearby forests of the planet the Galvan's went to inspect, seeing the danger they where forced to ask Azmuth to come help, he inspected what was going on and saw the "creature" turn to her human form many times, who cried out for help from the pain, after a scan he deduced someone was messing with D.N.A transformation and had used her as an experiment, hearing her cries of pain he helped her, enclosing a stasis field around her and making her go to sleep while he worked.

After a few days of scans and work he was able to stabilise her body and mind, but couldn't undo the changes to her D.N.A which he explained to her once she awoke, she was still linked to whatever did this to her and was now able to change her form into new Hybrid forms of her human self and the predators she was linked to, while slightly upset over what happened and not able to remember much of the details due to the pain and forced transformations she went through, she was thankful for his help, they helped her train with her new forms and powers until she was ready to leave.

She decided to travel to other planets for a short while before returning to Earth, where she met the Plumbers and Ben, after hearing about her from other worlds and her own tales they welcomed her and worked together to keep the universe safe, over time learning about the Nemetrix and those that experimented on her with it and gaining new predator forms along the way, becoming one of the greatest heroes in the universe.

 - Max Steel: "what if... Sydney fused with Ultimate Elementor" ( Max Steel 2013 TV Series - Episode The Truth Hurts)

when Sydney struck Ultimate Elementor's core there was a slight burst of energy, this energy wouldn’t have done anything if they hadn’t been trying to assimilate Max Steel, max's turbo energy and steel's Ultralink tech with the rays energy caused a feedback that struck both Sydney and Ultimate Elementor, causing a massive energy explosion, when the dust cleared max and steel saw Sydney standing, but she was different, she now had four different coloured core's along her collar (red, blue, white and brown), a light green armoured body suit with light yellow highlights and a yellow visor covering her eyes, but most apparent was the extra set of arms, a serpent like tail and her hair was now flowing yellow energy, cautiously they all examine her body only to suddenly have four familiar voices call out in confusion, that’s when the four cores detached from her into slightly different looking Ultralink’s and floated around them, they were the Elementor’s, that’s when they realised she had fused with Ultimate Elementor.

N-Tek soon showed up and they went back to base for more tests, the Elementor’s tried to run but when Sydney shouted at them to get back here she willed them back to her like a magnet, the four were stuck with her and her being in control, after the tests they deduced that it was a combination of the machine with max's turbo energy, steel's tech in making their turbo suit and Sydney's own will power that created not just the suit but also this new bond between the five of them, the Ultralink’s tried to argue and fight back but after Sydney but her foot down and gave them some good lumps they decided to just go with it for now, surprisingly earth was more alright with it than the others, more like a curious kid in Sydney's eyes.

Forge wanted to keep her locked up, not out of malice but caution of the Ultralink’s being known enemies,  but that was shut down by everyone, especially Sydney who could be as scary as Molly, especially with her new element powers, she also seemed to have access to the Elementor’s memories and began working things out, this lead to max and steel learning about their histories/origins sooner, they were upset at first but Sydney helped them calm down and get through it, they also learned that she could change forms from her Elementor form into her normal human form, with the four cores looking like a four gem neckless.

Over time they help her train with both Molly and Katherine's help, soon the Ultralink army makes it to earth with Dread's help, by this point the Elementor’s have come to slightly like Sydney's presence and working with her, they got fewer losses being on her team, it was near the end of the war that Metal Elementor tried to assimilate the five only for all of them to work together and assimilate him instead, adding his core to the middle of the gem neckless as a silver colour, adding some more armour to her battle suit. After some more pounding into Metal to keep him in line they ended the war, after the war with things calmed down they found a balance between normal life and hero work, continuing to help Max, steel and their future team as the elemental hero Gaia.

 - Army of the Dead: "what if... there was another zombie test subject" (movie Army of the Dead) 

The Las Vengeance team watched as the Zombie queen crawls along besides Burt, she is about to take him away when all of a sudden she goes silent and looks up, even the big guy behind her stills, the pair looking around as if trying to spot something, the others ask Lilly what’s going on but she has no idea as this has never happened before, that’s when they all hear it, the sound of metal banging and tearing, they follow it towards the wall, and soon a female figure lumbers up from the other side, she was fair skinned, white hair tipped with red in places, the black and whites of her eyes where switched and she was wearing torn clothing of a white patient gown, with a straight jacket that was missing its arms, and army cargo pants torn below the knees, all with splashes of red that was clearly blood, she walked up the edge of the container and let out an ear-piercing cry that the queen replied in kind, this woman then leaped, defying logic in the height and distance she covered, and landed just before the queen.

She stood tall as the queen moved over to her, growling and letting out odd chirps as she got near face-to-face, the team held their ground waiting for a fight if need be, the woman surprised them as she calmly lifted her hand and stroked the queen's face, who closed her eyes in pleasure, the woman then spoke "nice to meet you Athena" that’s when a black substance reached out from her fingers and into the queen, soon the queen's body began to change, altering into a far more healthier appearance, the red and white of her eyes turned black making her yellow eyes stand out more, the drastic change shocked the team and more so when the queen spoke "he has told me so much about you".

Scott took this moment to be brave and ask who was she and how did she do what she did, the queen and bodyguard growled but calmed at the woman’s hand, she went on to say she was the second test subject of Area 51, just like Richards, or as they call him "Zeus", she had thought she was being cured of an illness while he had volunteered for super solder tests, they had talked while going through tests, getting close, but soon learned the truth, that the tests where for bioweapons, they soon lost their minds and became what was called zombies, he had been transferred to another location, which lead to the Las Vegas event, while she had been kept and further experimented on, but what the government didn’t know was that they were really helping her, improving her mind and virus with more virus strands injected into her, giving her back not just her mind but also allowing her to alter herself and other infected of an Alpha level, becoming stronger and more dangerous, even able to sense what other infected where doing, but she kept it hidden, pretending nothing was changing, letting them become lax in security, until she struck, she broke free and torn the facility apart before they could call for help, killing everyone without remorse for what they did to them, after she ran straight here to be with her lovers, she then asks why they are here.

Not seeing reason to lie Scott told her of their mission, the missing woman and the missile, after a moment she looks to the big zombie and gives a mental command, he grabs Burt and drags him away, she tells them they are free to collect their money and to be careful of the non-Alpha's, the ones they are used to, as she cannot command them, and that the woman will be sent to them as there is no need for them, with that she and the queen leaves.

The pair soon come to the other Alpha's and Zeus, she does the same to them all as she did the queen, hugging Richards and Athena while stroking the queen's pregnant stomach, through their minds she tells them of what they must do and they agree, they kill Burt as he is a snivelling worm and the women are released, they head to a section of the wall and quietly climb it, making sure no one was around as they made their leave before the missile struck, with their more human appearance they snuck into a town and gathered new clothes, starting their new lives, hiding in plain view, with no one knowing.

Chapter Text

Heather was hurt, having been badly hit by many arrows, Windshear was scared for her rider, having just gotten them away and hidden in a cave within a forest on a lonely island, she knew her rider wouldn’t make it back to the island with the other dragons and their riders, so she made a choice, she first carefully pulled the arrows out with her teeth and opened the clothing to expose the wounds, she then bite into her paw and drew blood, she first covered the wounds in her dragon blood then had it flow into and down her riders throat, after which she carefully but tightly wrapped around her rider like a mother to her laid eggs and covered them both with her wings.

Heather was on fire, her insides like molten rock, her skin itchy like thousands of fire ants crawling just underneath, and her bones felt like wood being broken and reformed as burning metal out of a forge, she had never felt this kind of pain before and it just kept going, an eternity seemed to pass before it slowly cooled down until she felt fine once more.

Heather woke up the following day feeling better than she ever had before, once Windshear unwrapped from their protective nest Heather was finally able to see her body, which had greatly changed, she now had silver metal scales running along the back of her arms and outer shoulders, along her collar down the middle of her chest and sides to her abdomen, outer hips, the outer half of her thighs, covering her lower legs and back, she had silver wings coming from her back just like Windshear's along with a similar tail extending from her lower back, her teeth where slightly sharper, her nails on hands and feet where now like retractable claws, and she had a pattern of silver scales along her forehead from temple to temple along with a few silver locks within her black hair.

She was then surprised by Windshear talking to her, explaining that her life was at risk and so she gave her blood, knowing that her blood would change her, Heather is slightly shocked at this but greatly thankful to her dragon's loyalty and affection.

A few hours passed with her learning about her new body before the other riders and dragons showed up, Heather had to stay behind a bush as her clothes had been greatly damaged from her transformation, after getting over the shock and getting some spare clothes that where altered to fit, with Astrid nearly caving in Snotlout's skull when he tried to sneak a look, they were told of what happened, Hiccup and Fishlegs theorised that this may have been where the Lycanwing legend came from, a dragon giving blood to someone to save their lives, when asked why this hasn’t happened with other drinking the blood of dragons or their meat in old times the dragons explain through Heather that it had to be a willing thing, that the gifts of a dragon could not be forced or taken against their will.

After this and informing other’s things went on as normal, only with Heather now having an edge in flying along with Windshear in and outside of battle, some took a while to get used to her changes but it was no different than when learning to live with dragons, only easier. Time passed and a few others got transformed by dragons either as a gift of friendship or when seriously injured, they found out that those born from half-dragons are also half-dragons, leading to a new age of dragons, Vikings and dragonlings to be born.

 - DC: "what if... Barbara Gordon became the Man-bat" (Batman: The Animated Series 1992) [given by 3mtsims AO3]

Batman was worried, that was a rare thing, but this had him worried, Joker had heard about the mutating formula from Gotham Zoo, had broken into and taken the old research the family had locked away after the two incidents, while he would have preferred it destroyed he understood how such research could help the deaf, he should have made a proper vault for them to store it in, but he couldn’t dwell on such things now, he and Robin where to meet Batgirl at the Jokers hideout and hopefully stop him before it was too late.

Little did he know Batgirl had already arrived and was sneaking around, she soon found Joker working while he chuckled madly, she would have watched longer had she not needed to jump away from Harley's mallet that dented the railings, after a few moments of dodging she hit Harley off and down onto table some thugs where playing cards at, she soon followed down ready for a fight.

Joker made his big show of how he wanted the bat to show first but a pre-performance wouldn't be unwanted, that's when he took a syringe and injected a nearby thug, and in seconds he mutated into a man-bat, that's when Batman and Robin burst through the skylight, grinning the Joker monologues about him being a little late and that this was one of his best jokes, to have Gotham, that was protected by the bat, destroyed by bat monsters, that's when the new man-bat went on the attack and Joker injected the remaining formula into three other thugs before he and Harley made their escape.

The bat team fought against the mutants, being able to take two down before the other two fled into the sky, leaving the bats with the remaining thugs, Batgirl told the pair to go after the mutants while she handled the thugs, and with that they split up. Batgirl handled the thugs with ease and soon they were knocked out, but that’s when one of the downed man-bats got back up and swiped her back drawing blood, Batgirl went on to fight it but during the fight, she started getting hot and her body twitched in pain.

Batman and Robin arrived back with their mutants in time to watch as Batgirl turned into a female Man-bat and continued fighting the other man-bat, Batman jumped down to the Joker's workbench and quickly went over the details, finding that he had used a mi of the mutant formula and Bane's venom, altering so the mutation can pass onto others from injury, like a werewolf. That is when Batgirl flung the man-bat into the wall, knocking it out for good, she then began to advance on the heroes before Batman threw sonic pellets that messed up her hearing and then hit her with a stun dart, the pair then loaded the mutants and the research, returning to the Batcave.

Curing the thugs was easy, however, Batgirl wasn't, having been exposed to other chemicals in their line of work and being mutated from a man-bat instead of injected had left complications, they were able to return her to human form, but she was now alter permanently, able to shift between human and girl-bat at will or partly, while a little upset at the Joker getting a partial win Barbra was slightly happy to have some powers and able to fly under her own power. They helped her train with her new abilities and alter her clothing so it altered form with her transformations, new tools that she can use with her normal hands and limited digits in bat form, in the end, it wasn't too big a change but opened up new doors for them with her abilities ranging from flight, super hearing, claws and even a sonic screech, even Supergirl came to like them as she got to fly around with her friend.

 - Teenage Mutant Ninja Turtles: "what if... April O’Neal got mutated into a cat mutant at the beginning of TMNT (2003)" (TMNT 2003) [given by 3mtsims AO3]

they were doomed, surrounded by robotic stone-crunching monsters no higher than their knees, fighting beside four mutant turtle brothers, April never thought this was how she would go out, as she was working with Don to break through the computer defences a Mouser leapt at her, jaws wide to tear her apart, she instinctively swiped her hand out as if to batter it away, what happened surprised them all, her nails became long, sharp and claw-like, tearing the robotic monster to pieces, as she stared at her hand in a mix of awe and horror she suddenly felt her heartbeat pounding in her chest, so much that she gripped her chest and began to change.

The turtles continued to batter the robots away as they watched in awe, April grew a few inches with her muscles becoming a bit more defined, orange fur now covering her body, cat ears and tail sprouted from her head and lower back, her shoes tore open as she gained claws on her hands and feet, her teeth became sharper, her hair slightly wilder like a lions mane and her eyes became slit like a cat with the green shining more clearly.

Once her changes had stopped she was like a predator, she swiped at a few mousers that got close, destroying them like toys before turning back to the computer, the others tried to talk to her but it was like she was on autopilot, soon the mousers stopped, when asked what happened that is when April finally spoke, explaining that she was able to activate their self-destruct program, with that they all escaped before a massive explosion went off.

Now in the darkness of an alleyway, April began to panic and start asking what happened to her, the others were just as confused as her, they made it back to the layer and after explaining everything to Splinter Don started some tests with April on her D.N.A., they found traces of mutant strands like the families along with cat D.N.A., when asked how it could have happened Mikey spoke up, he said that one of those mousers had nicked him and she was a bit banged up, could his blood have mixed with hers, this made Don think and run a deeper scan with Mikey's bio, it was true, the mutant traces where from Mikey, April then said she encountered a cat during her escape from the Mousers, this lead to them concluding that some of the cat's hair must have stuck to her and mixed with Mikey's mutant blood that got into her systems and was activated from the stress of the fight, causing her mutation.

Mikey is sorry for this happening but April says none of them could have known this would have happened, she just wished she could go back up without needing to hide, that's when her fur and cat features receded into her body and she returned to her human appearance shocking them again, Splinter suggests she think of her cat form again and just like that she was a mutant cat girl once more, Splinter says she has the ability to shift between her forms, giving her the best of both worlds, he offers to help train her with her new abilities and fighting skills, she accepts.

Time passes with April opening her uncle's shop and training with the guys, getting better with her powers and computer skills, other than being more a part of the Turtle's adventures things go as they did in the original timeline, only with Casey saying her cat form is just as beautiful as her human form, and he has the marks on his back from her appreciation.

- Ed Edd n Eddy: "what if... Ed's story was actually what happened?" (Episode Once Upon an Ed) [given by anonymous reader (Guest) AO3]

chaos, destruction, that was their world now, the mutant Kanker’s bringing destruction to all in their path, only kept slightly at bay by the military, but even that wasn't much, the Kanker’s caused ruin to many towns and cities, using buildings like thrones for their own amusement and eating them like candy, the only ones still in the war-torn area were the kids of the Cul-de-Sac, hiding under the junkyard in their own built base made from all the scrap.

When the mutant Kanker’s tried to grab the Eds they ripped up the house, allowing the three to escape into a torn-up section of the sewer, from there they snuck around, bringing the other kids down with them, there was arguing but they understood that this wasn't a time for it, so they kept travelling until they came out in the junkyard where they hid for a few days, sneaking around the town to gather supplies, Double D was able to make a radio with the junk to get in contact with authorities, unfortunately, the area had been evacuated and they couldn't get to them, and they knew they couldn't leave without the Kanker’s getting them.

That is when they decided to fight, they started by digging a base, Rolf, his animals, Ed and Jonny were key to this, the digging and foundation were made with a combination of metal and fast-growing trees Jonny had used in his superhero identity, Double D and Kevin working together to design it, with the others gathering supplies, in a week they had a powerful underground base.

In the weeks that followed they tried to fight against the mutant Kanker’s but their equipment was just pitiful, that's when Ed remarked "To fight an enemy sometimes you have to become the enemy" Double D realised what he meant and said they needed to find out what caused the Kanker’s to mutate, they searched the remains of the Trailer Park, that's where they found the mouldy remains of the Over-Radiated Mashed Potatoes, once back at base Double D was able to do tests.

After a few days, he explained what he found, the radiation had caused the nutrients within to accelerate the growth within the Kanker’s and give them unique abilities as they have seen, when asked if they could do the same he said no, that they had been left too long and would cause a limited mutation that would cause the eater great pain and possibly death, but they still contained lots of power and unique mutation power, so he can instead create weapons for them to use that will be effective against the Kanker’s, with this good news they got to work, getting everything he needed, after a week of work he was done and all were outfitted with new weapons and gear to battle the Mutant Kanker’s.

 - Ben 10: "what if... the 2nd Body Swap spell worked... sort of? VERSION 1" (Episode A Change of Face) [given by Jokermask8 AO3]

Gwen and Ben made their way through the smoke, bumping into each other, Ben asked if Gwen was back and she remarked "Of course doofus" confirming it was her, but then she paled and pointed to his wrist, he looked and spotted it was bare, the watch was gone, that’s when they heard laughter and turn to see Charmcaster standings tall, magic crackling around her and on her wrist was the watch, Gwen pulled out Charmcaster’s spell book from her pocket and tried to use a spell but nothing happened.

Charmcaster then explained that the spell worked in a way she didn’t imagine, instead of just swapping bodies it gave her both the watch and Gwen’s magic, boosting her own, they tried to stop her but she just waved her hands and they along with their grandpa where bound by the wood of the ship, she then used the watch to transform, turning into a female version of Heatblast only with the rock skin being black like Obsidian with magenta glowing lines, and the yellow and red flames being replaced with white flames, forming fire orbs in her hands she thrust them down and unlike Ben's flight of a rocket she went flying like a jet with no damages.

Later on, the family got out of their bindings and tracked Charmcaster with the Rustbucket tech and the signal from the watch, travelling many miles and pushing the rockets to the red they were able to reach her just as she passed through the Door to Anywhere, heartbroken at the loss of both the watch and newly discovered magic they ask Max if he knows ANYONE that can help them, he says there is and goes to a locked hidden safe, he pulls out a small device and tells them it was an amplifier, he turns it on and speaks into it, calling out "Verdona, I need you" with deep affection, that is when a flash of light shines and Verdona in her elderly form appears.

Max introduces them and explains who and what she is, the pair are surprised to find they are related to an alien and one that can use magic, Verdona is happy to meet them but knows this isn’t the time as she is upset at her family having such important things taken from them, so she opens the doors and guilds them through the realm, where they come across Charmcaster fighting Addwaitya, she was transformed as Diamondhead which now was purple crystal with black rune carvings across the body and what appeared to be a pulsing black energy core inside her body.

Addwaitya summons strong magic that sends the woman flying and crashing away, the family go to her location to find her knocked out and de-transformed, they get her away before the mutant turtle arrived, sometime later when she wakes up Charmcaster tries to leave to keep fighting and they hold her tight with Verdona's mana, when demanded she give back the watch and stolen magic she said no and needed them to beat Addwaitya, when asked who he is she angry explains it all, that he took over her home, destroyed her people and her father, forcing her and her uncle Hex to escape into the human realm, that she would end him, get the Alpha Rune and bring her father back and that none of them would stop her.

Verdona said she was being foolish, that even if she didn’t bring her father back he wouldn’t want lives exchanged for his own, as that was the only spell able to bring the dead back, an exchange of life, Charmcaster went to argue but Suprise Hex showed up, telling her that what they said was true, that he knew his brother's heart more than anyone and that he would undo the spell should she cast it, as he wasn’t one for taking life, she cried angrily and shouting what was she supposed to do then, and he replied "life, live a long and good life, that is what he wanted when he gave his life for us" moments passed with her crying.

It was Ben who made a surprising offer, that she travel with them, he could show her how the watch worked and the alien's skills if she used it for good, Gwen also agreed, that she could help teach her how to use magic like she did before, Max nodded saying there was always room for more, Hex said it was a good idea for her to have time with others for a change, she was surprised by this but agreed, Ben said they needed to beat turtle head first though, and with that they planned.

They made a surprise attack, the 3 magic users attacked while the family got to work with a giant spell circle, they bashed Addwaitya around from all sides and sent him flying, Charmcaster using Wildvine (looks like Gwen 10's version), which now had orange skin with purple curved thorns and pink flowers on places, flung him over and tied him down into the finished spell circle, the 3 magic users got into place and chanted spells that drained Addwaitya of his strength and magic long enough for Ben to nab the Alpha Rune, they then sealed him away inside a thick stone prison and sent him deep into the realm to never be seen again.

Afterwards, Hex took responsibility for Legerdomain and the Alpha Rune, saying he would bring order back to the land in his brother’s name, the family left the realm with Charmcaster who was able to return Gwen’s magic but the watch was stuck to her, Ben was upset but Max helped him out by teaching him Plumber tech, Verdona stayed a while to help teach the basics and some advance magic to the girls before leaving for a time.

Time passed and they became a hard-hitting team that the universe didn't want to mess with.

 - Crossover: DreamWorks Dragons / Marvel "What if... Mjolnir landed on Dragon's Edge" (takes place in Dragons: Race to the Edge) [given by Jokermask8 AO3]

As Thor’s hammer, Mjölnir, was flung through the Bifröst after its owner was cast out of Asgard, a stray strand of energy flickered out and struck the mighty weapon, while on the surface nothing to be seen had happened, something did happen, for when it was struck a second hammer had been created within the walls of the multiverse, it hurtled through the strands of the multiverse until it smashed its way into one far away, but not unlike home.

It was chaos, Dragon Flyers were everywhere, fire was almost all Astrid could see up in the sky as Dragon Riders and Wingmaidens fought as best they could, that's when a Dragon Flyer fired upon her and she struck the blast with her axe, leading to its destruction, as the Flyer passed her the Singetail's tail flicked out and flung her from Stormfly's back, falling through the air, Stormfly tried to go after her but was forced to dodge more shots.

As Astrid fell, fear gripping her heart along with determination, there was a thunderous boom and the sky seemed to shatter like ice as an object fell from it, the object was a hammer, small but somewhat impressive in its simple design. Instinctively Astrid reached out, as though it called to her, and just like that it shot right into her hand, which was followed by the sky instantly filling with thunderstorm clouds and lighting blasting down upon her, blinding all.

Once the light faded they saw something that made them all gap in awe and fear, there, floating as though she was standing on air, was Astrid but different, she now had armor that hugged her form, silver arm guards and boots that reached up to her elbows and knees, her leather Gladiator skirt with spikes now had a chainmail underlayer and metal segmented belt, her shoulder guards are now smoother with fur around the edges, both connecting to a red cap that stopped just behind the knees, a silver breastplate with golden edges, a silver and gold headband with tinny wings just above her ears that kept her hair back, and the hammer held in her hand, arcs of lightning sparking off her body in places.

When she opened her eyes they shone with bolts of lightning (think Thor powered up), that is when Stormfly flew over to her and hovered in place next to her rider, Astrid reached out and petted her dragon, resulting in another flash of lightning which lasted a split second, showing Stormfly now had light silver armor along her chest, legs, claws, skull, and tail, lightning also now flowing off her as she looked more deadly than before.

A dragon flyer tried to attack the pair only for Astrid to swing the hammer and send out an arc of electricity that destroyed his arrow and the dragon's fire as well as knocked them from the air, this seemed to be the kick that restarted the fighting, Astrid dropped onto Stormfly's back and the pair flew through the air like they were the wind itself, striking down flyer after flyer and even sending lightning bolts down upon the hunter's ships and send the hammer flying like an arrow that returned to her hand that did great damage to the ships, that is when an army of dragons appeared and helped to free the dragons from the flyers and destroy the ships.

Soon the fighting was over and all gathered again, checking on Hiccup and asking many questions about what happened to Astrid and Stormfly, who did not have much of an idea, she just felt like the hammer called to her, it was then that a new voice joined in, the group all looked to see a tall man in a blue rob and large bald head with white eyes, this was Uatu, The Watcher, he had come to explain what had happened and the hammer, to say they were shocked was an understatement, to know that in another realm there were real gods, or close to such at least and that Astrid was now a chosen user of Thor’s hammer itself, he remarks that she isn’t the only able to use it, which Snotlout takes it to be him and tries only to impact the floor and not budge it, others tried but nothing, Hiccup was the one to pick it up and hand it to Astrid, saying while cool he thinks it suits her best, getting a blush and kiss from his girlfriend.

The watcher left and time passed, with her new powers Astrid was a big help in both combat and construction, helping to free dragons and keep them in line while also improving their home island, making it a great stronghold and place to live for man and dragon alike, easily able to best those that meant them all harm.

 - Crossover: Totally Spies / Jackie Chan Adventures "What if... Jade is brought to the attention of WOOHP" (takes place in Totally Spies! The Movie) [given by wildfire377 AO3]

today had been the most active and stressful for Jade, Drago and his stooges capturing her family, gaining the demon chi, them attacking and destroying section 13, thinking Tohru had been crushed, fighting a demon army with the Talismans and the rest of the Chan Clan, Shendu being freed to fight for them while also finding out Tohru was alright, giving Shendu the Talismans to fight a powered up Drago, reversing the portal to such all the demons back in along with Shendu, Drago and the Talismans, and possibly being given the chance to train at section 13, once it was rebuilt... yea it was no wonder she collapsed into the hotel bed they were all staying at, at least the world was safe once again and no one was any the wiser.

Little did she know that someone had been paying attention, especially to her and her actions.

The next day they were helping to repair Uncle's shop, Jade wanted to help but Jackie said it may be unstable so it might be best for her to go off and have some fun as school had been put on hold for a while, Jade did and decided to just walk about, checking out the places she had adventures on. It was during this trip down memory lane that a large tube suddenly stretched out of a passing truck and sucked her up, she slides down the passageway until she landed on a red couch with three other slightly older girls.

After introductions, learning the girls' names were Alex, Clover, and Sam, they looked around the office for a few minutes, Jade remarked this was a spy office, the girls asked how she knew and she stated she had been in a government secret base for over a year so she knew what they looked like, Sam got their attention with some office supplies that turned out to be gadgets, Alex tried one only to set off a series of random laser blasts that forced Sam and Clover to take cover, Jade tackled Alex down making the gadget drop to the desk and stop, that is when Jerry and Tad, the pair explain that they wanted the girls to become spies, showing some of their greatest feats, the girls argued against this especially to Jade joining as she was a kid, but where quickly silenced when recordings of Jade's adventures the past year was shown, Jade was all for joining while the others straight up refused and where sent back to school while Jade remained.

While with Jerry, Jade voiced how Jackie wouldn't agree to any of this and try to get captain black to stop all this, Jerry agreed with her concerns and together they made a plan, she would go back and would receive a letter saying she has gained a random selection prize to a fun camp that tests both the body and mind, she would get her uncle to sign it and she would take the bus to the camp's location tomorrow which would be a WHOOP vehicle that would transport her back to them, with the plan set she was sent back and all went as planned.

When she returned the next day she watched as the other girls got streamlined into the training with herself, she took to it like fish to water while the other three had ups and downs, she was really good with the gadgets and fighting, but when it came to using vehicles she had to hitch a ride with the other girls as she wasn’t of age yet, something that ticked her off, when they were given their mission and new catsuits hers was slightly different to the others, it was skin tight and colored blue like her jeans but had an open orange short-sleeved hoodie that was only slightly hugged her and matching colored boots and gloves, her own gadgets where a little more tomboy like a watch communicator and such, with that they were sent on their way.

The rest of the events went as they did in the movie with Jade added in giving extra help and her own experience with crazy adventures, once over and Tad was locked up with the other villains they talked about her future and how to stay, Alex offered to have her stay with her and her family as they both liked animals and sports, they came up with the plan to say she got to know the girls at the camp and she was offered the chance to go to Beverly Hills High two years early from her combined physical skills and what she had learned at camp, with that they waited for the end of the week for her to go back and once she did she told her family of all the fun and new friends she had made (not mentioning the spy stuff) and the offer, Jackie was a little reluctant but at her eager and pleading face to go to a higher learning and be with friends he gave in, of course he had captain black check it all which he confirmed was all above board, with that Jade packed half her stuff and moved to Beverly hills, starting her grand adventure of being a spy with the girls.

 - Ben 10: "what if... Kevin's mom was also Osmosian?" (after Ben 10 original series when the Rooter kids attack) [given by Jokermask8 AO3]

Kevin was going crazy after going mutant for the second time, tying up both the Tennyson family and the Amalgam Kids, Gwen kept trying to physically knock sense into him but it wasn't working, young Argit was about to try calming him down with his quills only for a hand placed on his shoulder to stop him. Kevin laughed like mad about to eat a giant rock to power up until "Kevin Ethan Levin! Do you know how worried I have been!?" an enraged female voice made him freeze, everyone looked over to see a tall, fit, long black-haired woman wearing jeans and black short-sleeved shirt "MOM?!" Kevin shouted in shock which had everyone else gaping as well.

The woman marched up to him telling him off about how he ran away, leaving her worried and scared for him and how she had to call up all kinds of favours to finally find him, hearing about him going criminal, power crazy and so such, Kevin argued that it wasn't his fault but she told him it was always his choice in what happened to him, he said that he was a hero but she replied that a hero doesn't attack innocent people and cause mass destruction, in anger he lashed out but she surprised them by coating herself in stone, blocking his attack and then turning her hand into a massive hammer that she sent him flying away with a hit from.

He said she was like him and she said of course she was and if he had stayed and talked to her she would have taught him all about their powers, that it was time to stop this and just come home, her words made Kevin calm down and slowly return to normal as she spoke of how she missed him, as he did everyone was released, the Amalgam Kids attempted to make a getaway but the mother wouldn't have it, she turned on them and asked what they were thinking and where were their parents, the kids didn't have answers as they either ran away or didn't have homes, seeing this the woman decided that would change, she would take them in and Max even offered to help with his Plumber connections.

This moment was ruined when the Rooters came through a portal and said how disappointing the kids were, they ordered the kids to return, and almost like puppets the kids went to do so but Kevin's mom stopped them, she saw the look in their eyes and knew that Servantis was controlling them, she ordered him to let them go but he said she had no authority or power to make him, she looked to Ben and his watch asking if that's what gave Kevin his mutant form, he said yes but that he went crazy from it, she replied that she wasn't untrained like her son and touched the watch, to her it was like traveling down a tunnel with walls or tubes containing samples of D.N.A, some lite up while most weren't which showed which Ben had unlocked, she touched them and saw what each one contained and what they could do, she went down each one, choosing the ones she wanted by absorbing the energy into her before leaving, to her it was minutes but to everyone else it was a second.

She opened her eyes and stood up, and that is when her body changed, she became two feet taller, her skin became black, stone and crystal armor formed upon her shoulders, chest, forearms, and knuckles, chopper plugs on the back of her fingers with her hair braiding into three antennae with copper plug ends, shell-like plating along her forehead, green spikes sticking out of her biceps, her legs slightly change to large three-jointed hind limbs with film connected to the tibia and tarsus of her legs, black orbs formed on her feet, a black tail with five blue stripes from her backside with rock like sections along its length, and four large blue moth-like wings sprouting from her back.

everyone was shocked from the transformation, the Rooter didn't waste time and tried attacking, word being tried, the woman had launched herself with great power and speed that she was on them before they could twitch, she punched Leander sending him flying into the trees and grabbed Swift by the tail before she could fly far, swinging her down and crashing into the ground, Servantis tried a mental blast only for her to give one of her own that struck through his and blasted him down, Swift and Leander tried a combined blast but she absorbed it with her hair and crystals, the energy now in her fists she blitzed Leander with a furry of hard and powerful punches that dented his metal body with each shock infused strike until she gave a powerful uppercut sending him flying straight up, Swift tried to body tackle her but she went right through her as she went intangible and then used her tail to grab the Rooter and slam her up and down a few times before tossing her into a tree, Servantis had gotten over to the kids and had a blaster to Kevin's head, threatening her to stand down of he would kill him, she said he wouldn't as he needs Kevin, he hesitated and instead fired at her but his shots only left holes that looked like green slime that soon closed up, shocking him, she used his shock to pull him towards her with gravity, while throwing seeds at the kids that turned into strong vines that wrapped around them, keeping them safe and from being used, once he was close enough she used her gravity to spin him around like a top until he was dizzy then throw him at a recovering Swift, the pair tried to get up but looked to the woman standing still, she pointed up and just as they did Leander came crashing down on the pair creating a crater, before they could even muster a twitch to get up more seeds where thrown at them, vines growing and ensnaring them, Leander had his face pointed away from them all, Swift had her face and tail pointed to the sky and Servantis was held up towards the woman who breathed a cold ice mist that encased them all in ice, keeping them still.

She walked over to Servantis, her vines keeping the kids in place brought said kids over to them, she then focused the energy inside her and sent a mental blast into the man's own mind, searching for what she needed, she then linked with his Loyalty Neuro-Matrix, absorbing its energy and destroying it, then sent out more mental links to the children, destroying the link in their minds and locking him out of them for good, once done the kids collapsed to the ground and the Tennyson family rushed to their sides, she explained what had happened and how the kids where now free, when asked how she was in control when Kevin wasn't she explained that Osmosian's when untrained can go crazy from the power they absorb affecting their minds, but with training, mental strength, and experience they can overcome it and it won’t affect them again, it can also help to absorb mental abilities that protect their minds from the energy they absorb.

Max called in the Plumbers and told the Magistrata of what the Rooter had done, she had a full investigation and found out why the Rooters went to such crazy lengths, she had them shut down and banished to the Null Void, when asked what would happen to the kid's Kevin's mom stood by her choice of taking them in, even Argit, and give Kevin proper training with his powers as she returned to her human form, the Magistrata agreed and even arranged for her to have support so she can help the children train better and live what lives they choose.

Over time Kevin and Ben came to terms with each other and even became like brothers, helping to keep the worlds safe, Kevin's mom would take them on trips to other worlds to learn more about their alien powers and history, they still had threats like Vilgax, but with so many young hero's helping to keep things safe, it was an alright life.

She had used the D.N.A of Kineceleran (XLR8), Methanosian (Swampfire), Galvan (Grey Matter), Conductoid (Feedback), Cerebrocrustacean (Brainstorm), Orthopterran (Crashhopper), Crystalsapien (Chromastone), Galilean (Gravattack), Necrofriggian (Big Chill) and Polymorph (Goop).

 -  Kim Possible: "what if... the Synthoplasma did eat Kim" (Episode Mother's Day)

it was dark, so dark, and she was floating, she did not know who or what she was, just that there was something she was missing. She heard crying, crying from someone close by. She looked into the darkness and a faint image was ahead. A woman was crying. A redhead on her knees crying about her daughter. Why does that sound familiar to her, why was this woman so...important, like a beacon in the dark? She hated the crying, it hurt to see her like that. She needed to get to her. So, she moved forwards, moving like she was in mud but pushing through, closer and closer to the image, and soon the darkness turned to light.

Ann Possible​ couldn't believe it, her one and only daughter was gone, consumed by this blob creature to never be seen again, why did she tell Kim to talk to it, why didn't she act faster when it took her? Now here she was, alone on the train with the blob going to consume her next, is this what Kim meant by it being too dangerous? Oh, how much a fool she was.

Her attention was grabbed by the blob as it moved towards her, she had nowhere to go, trapped, all she could do was close her eyes and wait for the end, saying goodbye to her loved ones in her head... only for nothing to happen. She opened her eyes and met a green pair like her own along with a familiar if green gooey face. It was Kim, her daughter was alive and looking right at her! She threw her arms around her in a hug, crying tears of joy and asking if she was alright and how she survived, but the girl looked slightly confused, looking at her like she was trying to recall something "I...know you...your...your important...to me. right?" her confusion and slightly gurgled voice made Ann pause but nod saying she was and asking what she could remember, Kim said she was in darkness, just floating, then she heard her crying and just had to reach her, to help her stop crying as it hurt to hear it.

The pair was taken to Global Justice HQ along with the scientists that made the Synthoplasma and Wade, they performed many tests and asked Kim many questions, they came to understand that Kim's higher organic and complex human mind had overridden the creature's simple mind when she was consumed, but her mind had been spread throughout the body and that was why she was having a hard time with remembering, it was like amnesia where people could get back their memories, they just had to help her remember, but she was stuck as this new creature with new abilities they would need to help her discover.

They took her home and for once, the twins took it seriously as they almost lost their sister for good, everyone helped her out, showing her old pictures and family movies, and as they did her memories returned a step at a time, she was even able to smooth her body out to be more like her old human appearance instead of a humanoid glob.

While this happened GJ helped keep the villains Kim went up against at bay so she could recover easier, but of course, news reached a few of Kim's condition and one tried to attack while she was "weak", this was Professor Dementor. he launched an attack on her home town, causing a lot of chaos and destruction, it was this attack that helped kick Kim's main memories into gear, she along with Ron went on to repel his attack, using her new body and abilities to stretch/reshape her body and absorb what she wanted she took out his men's weapons and sent them flying with a combination of her fighting skills and reshaping her limbs, it was stopped by Ron hitting the power core of his mobile base and making him flee as it crashed into a field.

Some more time passed with helping Kim regain the last of her memories and retraining herself with her new abilities before she went back into the field better than before, kicking bad guy butt more than ever.

- Jackie Chan Adventures: "what if... the vampire was different VERSION 1" (Episode Chi of the Vampire)

Jade pried the coffin table open and took a look inside, she was surprised to find a slightly withered body of a male adult with slicked-back black hair dressed in red and black Victorian-era clothes. Before she could decide on what to do its eyes suddenly opened and lurched at her, she was not able to close the lid in time before it grabbed her and sunk its sharp teeth deep into the side of her neck. Her screams of terror and pain echoed throughout the building alerting the others and making them drop everything and rush to her location, they came upon her lying on her side holding her bleeding neck in pain.

Jackie was by her side instantly with Uncle as Tohru stayed close and looked all around ready to fight what attacked his young friend, as Uncle pulled out some herbs and gauze to stop the bleeding Jackie asked what happened, she weakly pointed to the coffin table and Uncle knew what had happened from one look, he said that there was a vampire loose in the building, Jackie wasn't sure and said it could have been a wild animal that attacked, but Uncle pointed out the teeth marks on Jades neck was human in shape, that was when slow clapping was heard.

They turned to see a man in Victorian clothing standing at the opposite side of the room, he spoke with elegance, saying he was thankful to the young maiden for unintentionally freeing him, that her young, strong virgin blood had helped revive him and he would enjoy her company soon for all eternity. When asked what he meant Uncle explained that he had bitten Jade and if he was not destroyed before Jade turned into a vampire herself then she would be forever a vampire, the man was impressed by the elder's wisdom and knowledge, but it would be impossible to kill him as you needed the right tools to do such, which is why he was only sealed and killed, not that they would have a chance as he then attacked them.

Tohru was quick to defend as he battered the vampire away through a wall, but it did not keep him down for long as he got back up and was on the attack again, keep the sumo moving. Uncle told Jackie to help Tohru while he looked through the books for answers, Jackie asked about Jade and was hit on the head by Uncle who stated that if they had a chance to save her and themselves then Uncle needed time to find the answers to defeating their foe, that they had little time to waste. Jade grabbed Jackie's arm and told him to kick the bat's butt, he nodded and was off as his niece fell unconscious and Uncle got to work.

Jackie and Tohru used all their skills to combat the vampire, leading and crashing him through many rooms of the building, doing all they could to buy Uncle the time he needed, said elder was going through books as fast as he could while telling Jade to hold on, as all this happened Jade was falling in and out of consciousness, her body feeling like it was on fire and frozen at the same time, as though she was slipping away from everything yet everything was slamming into her skull, it all hurt so much.

The battle of the three men came back into the library with Tohru and Jackie being flung around like potato sacks, Uncle was able to find what he needed, what needed to be done was carve the Vampires name into a wooden stack of oak wood and have it soaked in holy water that had a hot piece of iron dropped into the waters, luckily he was able to find the history of the building and that the vampire was once the lord of it until he got hungry for power and made a deal with dark forces, so he was able to learn his true name, and they had the needed items in the room and he had just finished carving the stack when they had broken back into the room, the vampire saw his actions and lunged towards him making him yell out.

But before he was grabbed an orange blur tackled the vampire through the wall, it was Jade, but at the same time it wasn't, she now had red-colored eyes, sharped fanged teeth, slightly pointed ears, and her skin tone was slightly paler, she shouted for Uncle to finish up and went on to fight the vampire with Jackie and Tohru joining her soon, Uncle got to work and soon finished the weapon, he tossed it to Jackie and drew out his blowfish to send a blast at the vampire, knocking him down just long enough for Tohru and Jade, now with enhanced strength, to hold him down so Jackie could jump up and slam the stack into the undead man’s heart.

The vampire screamed out and threw them all off him, stumbling around and screaming as cracks formed along his body with light shining through them and parts of his body crumbling into ash for a few moments until he exploded with a flash, leaving nothing behind. Jackie cried out in joy at their victory but went quiet at Uncles tear filled face, he then saw that Jade had not changed, her new alterations remained, Uncle explained that they were too late, Jade was now a vampire, forever. A few tears fell from them all as they hugged Jade, comforting her as much as themselves.

They spent a day recuperating from everything, having section 13 come to assist them, Uncle had some harsh words for the owners who tried to trick them with the coffin table and what they caused to happen to Jade.

Afterwards, Uncle explained that Jade didn't have much to fear as many tales of Vampire weaknesses were not true, while daylight was harmful to her it wouldn't destroy her and it was only because she was a new-born vampire, over time that would fade and she would be able to go out into the sun, as for the not aging that only goes into effect when she reaches the prime age of 25 or 30 and even then she could change how she looks however she wants, she also didn't need to fear turning those she bites as she needs to actively inject her own turned blood into the one she bites to turn them into vampires, so no need to worry about accidentally biting someone, garlic also had no effect, that was just because a vampire had an allergy to them when they were human, and a stack only works if you did what he had done.

After everything they went back to section 13, where they created a special department for magical study, given Jade’s new changes and the past encounters with magic and demons, with her being a part of it and supplying her with a steady supply of blood, Uncle also mentioned she only needed a single pack a week to stay healthy and more would just make her stronger until it ran out of her system.

Time passed and everyone got use to Jade's new lifestyle and abilities, it even came in handy when more supernatural creatures started coming out of the shadows, most bad with very few being good, those few good would become allies and help Jade further her skills and abilities, all while her family stayed by her side in this new age of monster fighting.

 - Jackie Chan Adventures: "what if... the Netherworld had side effects VERSION 1" (Episode Demon World)

The Chan clan was in trouble, the last four demons had the J-Team and Shendu most of his talismans back, Jade rushed to the book to try and give them an upper hand, but was stopped as she and the others were pulled into the air by Shendu's powers and taken outside to then be buried in the ground up to their necks by Dai Gui, the demons then went on to say what they would do to them, turning them to ash, drowning them, sinking them into the earth or throwing them into cold outer space.

Shendu then says why not all of it, saying they should make Jade watch as she was the one to cause all of this to happen, that's when they separated them, Viper was placed inside a sphere of water to drown, Tohru floated upwards slowly, El Toro and Paco sinking into the ground, and Jackie and Uncle surrounded in flames of intense heat that had them on their knees gasping, Jade was doing all she could to get free, to somehow help her family, to do something all while the demons laugh, that's when something within her sparked, in anger she shouted out and that's when things changed.

Her eyes glowed red as the ground shook and large roots burst forth, striking the demons away and cutting off their powers, the plant limbs caught a falling Tohru and pulled El Toro and Paco free from the ground. Everyone watched in shock as Jade rose from the dirt, her skin becoming a plant green as tree bark grew on the back of her arms and front of her legs, vines grew from out of her back, her teeth becoming slightly sharp, her hair extended down to her mid-back with different flowers blooming along her dark locks and small horns poking out of her temples.

Jade did not waste time as she threw her hands forwards and large roots burst forth, knocking both Shendu and Dai Gui away, Bai Tza surged forwards as water attempting to slash at the girl only for a thick bush to pop out and make her splatter all over the place, she reformed quickly but a tree burst up from under her sending her high up. Jade was then pulled into the air by Tso Lan attempting to send her sky high but she sent her vines to latch onto him keeping her still then summoned tree branches to grab him and pull him sharply into the ground, making him release her and have her crash down onto his back like a missile, she then bound him to the ground with more roots just as Dai Gui charged at her with an earth wave, she made giant tree's burst up making the wave fall to pieces and then sent her own vines to grab him and crash him into the ground several times before launching him into the created trees to tie him up in their branches.

Shendu then made his appearance by super speeding right at her and hitting her with a powerful punch, sending her flying and crashing through boulders, the chan clan cried out in worry only to slightly calm down as Jade got back to her feet, she then roared as she made a wave of thick roots and trees burst forwards at the dragon, who launched his own attack of fire and heat beam eyes, burning into the rapidly approaching forest but only able to make it come to a standstill as a constant stream of plant life kept coming.

That's when Bai Tza came crashing down behind Jade and reformed with claws at the ready to strike, but Jade merely stepped aside and stopped her stream of plants, resulting in Shendu's attack blasting into his sister and making her burst into steam with a cry of pain, he stopped only to have his body and limbs grabbed by giant tree's and was lifted up into the air, his head point straight up and tower sized plants holding his limbs tight, unable to move or use his powers to get free, Bai Tza was almost reformed only to have an infinite number of plant limbs form and wrap around her in a sphere, tightly compressed sealing her within so her water could not escape, the sphere as thick and big as Uncles shop.

After a moment Jade calmed down and fell to her knees, the other rushed over to her, she pulled out the torn page with her name and gave it to Uncle, telling him to fix everything while she held the demons trapped and to make it so they all appeared together at the point before they went to her parent's house, with a nod he runs off to do just that.

Afterwards, they all appear in a forest outside of the city where her parents are, all fine and back to normal, but with Jade still in her new form, they all talk and ask how it happened, Uncle performs a few spells to test her body, he then comes to the conclusion that Jades time in the Netherworld infused her with demonic chi, this wouldn't have done anything but her tearing her own name from the book and the demonic energies filling the world had allowed it to grow and burst forth with her strong emotions at the time, transforming her into half a demon, her powers linked to nature as that was her strongest element as she cared for both nature and animals, when asked why she didn't go bad he explained it was her strong and abundant good chi that helped balance her out and keep her mind from falling into evil.

After some trial and error, she was able to transform back to her human appearance and went to see her parents, some time passed with Jade mastering her new abilities and learning magic due to her new powerful magical nature, bad guys still showed up but was easy to beat back, though she had to keep most of her powers hidden to not cause a scene unless it was big foes and outside of cities, but life was certainly interesting now with a half-demon nature wielding niece.

 - Jackie Chan Adventures: "what if... the Netherworld had side effects VERSION 2" (Episode The Eighth Door)

the Chan Clan was worried, Jade had been in the Netherworld for hours now, they had gained the Pan'ku Box and were trying to figure out how it worked, Uncle was able to go into a trance and reach out into the other realm, but what he would find would shock them all.

Uncle's spirit head appeared in the realm and looked around, he was confused, the spell should have brought him right to Jade's location, that's when he saw a figure leaping towards him, he hid behind floating rocks and observed, the person flipped mid-air and fired off a chi blast at the distance, he looked closer and was shocked, it was Jade but she appeared as a young woman of 16 years old, she was missing her shoes showing slightly scared feet, her hoodie tied around her waist, her jeans now like shorts, a black piece of torn fabric wrapped around her budding chest like a sarashi and her hair was now a wild main that came to just under her shoulders.

The teen Jade leaped to the side as a bolt of lightning flew past her, revealing Tchang Zu, Bai Tza, and Dai Gui were chasing her, she performed a small chant making her hands glow before jump-spinning and blasting Bai Tza away before backflipping to avoid boulders from Dai Gui, dodging both rock and lightning she got in close and performed an over jump, grabbing the earth demon mid-flip, and tossing him into a reforming Bai Tza, she then spun around just as Tchang Zu tossed a large lightning bolt, summoning chi to her hands she spun away, avoiding the shot but at the same time grabbing it and with a swirl launched it back at the demon making him stagger.

The three demons rose up, and just as they powered up attacks Jade powered up her own chi blast, just as they attacked she launched her own resulting in a large explosion with dust and smoke filling the air, once it cleared Jade was gone and the demons shouted out in anger, quickly leaving to find the young human once more, after they left Jade flipped up from over the ledge of the platform and took a breath, that's when Uncle revealed himself, Jade was surprised but overjoyed, saying how she knew they would find her someday, Uncle was pleased to see her but asked what happened, why was she older, Jade was confused saying that's what happened after 6 years, Uncle said it has only been a few hours, that's when they realized that time must flow differently between the realms.

Jade went on to describe her time in the Netherworld, that over time staying out of sight she found an old library that was the demons, it was thrown into here when they were sealed so no one would try to use their magic, but it had more than just their magic written down it also had chi spells and teaching scrolls, she spent all her time reading and learning from them and was able to get the basics of magic down in the years she's been there, between that and fighting the demons she grown quite strong, she also said that Shendu told the other demons a few months back that they could use his door to all escape, Uncle tells her it's a lie and that only one can get through and it must be her, he asks about the Pan'ku Box and how to solve it, she gives him the answer just as Hsi Wu and Xiao Fung find her and start attacking, making Uncle have to leave and say that at this rate she will have to wait a few more years, which she says is fine and she will be waiting before she attacks.

Uncle informs the others of what's happening, and they are greatly worried about both Jade fighting the demons and her aging, if they don't free her soon it will be too late.

They soon arrive at the portals location only for Shendu to stop them from opening the portal by taking the Pan'ku Box, that's when they use the original method with a sword and forced his spirit out of Valmont, when his spirit bursts into the Netherworld his siblings are nearby but in battle, he gets blasted aside by a chi blast and looks to see who it was, it was Jade, now 22 years old, she now had ripped fabric wrapped around her feet and legs in a cross like style up to her knees, the remains of her hoodie as wrappings around her fists and forearms, and her hair, now down to her waist, held up in a ponytail, all while she had chi coating her hands and feet as she floated in the air.

She ducked and grabbed Bai Tza by the tail and used her like a whip to smack Hsi Wu and Tso Lan away before throwing her into Tchang Zu making them both get electrocuted, then grabbed Dai Gui's fists as he tried to smash her and instead smash him into Xiao Fung who tried to sneak up on her to blow her away with his wind, she then promptly kicked them into Po Kong's face making her tumble back a bit, distracting her just long enough for Jade to power up a big chi blast in her hands and launch it at the giant, blasting her back and into the rest of the demons, with this Jade quickly pushed the remaining chi energy in her body into a blast and rocked straight through the portal.

She came rolling out of the portal as it closed behind her, forever, coming to a stop on her back she looked up to the night sky, the stars and moon being the most beautiful thing she had seen in years, she was free, finally free, the realization made tears come to the corners of her eyes, tears that fell when her family came to her side, she held them close, just hugging them as she cried and they understood as they held her close as well.

They returned to Uncle’s shop, Jade having some slight problems sleeping due to thinking she would wake back up in the Netherworld, but was able to get some of the best sleep she had in ages, especially food, apparently you didn't need to eat in the Netherworld, you were kept alive and healthy by its energies, Captain Black came by with a few medics to check her over and update the records, they came up with the story she went through a rare growth spurt both physically and mentally so she needed special home school teaching to get her up to her body level, this would explain for her leaving school and changes.

Time passed with everyone adjusting to the older, chi master, demon butt-kicking, calm-minded Jade, things went on as normal, bad guys showing up, magic object being found, saving the world, only with two chi masters, one being an expert demon fighter, things where a little easier to handle now.
