Chapter Text
The Justice League did not understand the Titans.
They respected them, certainly. The Titans had saved the world more times than most people realized, handled crises quietly before they could escalate, and somehow managed to maintain functioning relationships with one another despite years of shared trauma and increasingly dangerous missions.
But understand them?
No.
The League thought the Titans were chaotic.
Too loud during meetings.
Too relaxed in combat briefings.
Too likely to turn mission prep into a food fight.
Half the time the Titans looked less like Earth’s premier young hero team and more like a particularly dangerous group chat that had somehow gained access to military-grade weaponry.
Which was why no one—not even the League—fully realized how terrifying they actually were.
Not until Batman accidentally proved it.
It started during a Watchtower training session.
“Again,” Batman said flatly.
Green Lantern groaned. “Bats, we’ve been at this for two hours.”
“You’ve been failing for two hours.”
Across the simulator room, Flash leaned against the wall dramatically. “See, this is why nobody likes your training
exercises.”
Batman ignored him and adjusted the simulation settings.
Superman sighed. “Bruce.”
“The response time is sloppy. Communication is inconsistent. You’re relying too heavily on individual power sets instead of coordinated tactics.”
Wonder Woman crossed her arms. “We succeeded.”
“You survived,” Batman corrected. “That is not the same thing.”
Hal Jordan threw his hands up. “We are grown adults, not your sidekicks.”
A beat of silence.
Then Batman said the worst possible thing.
“Yes. That’s the problem.”
The room went still.
Flash blinked. “Excuse me?”
Batman finally looked up from the controls.
“The Titans outperform you consistently in every team-based simulation.”
That got everyone’s attention.
“Hold on,” Hal said slowly. “Are you saying your kid team is better than the Justice League?”
Batman considered that.
“Yes.”
“No.”
“Yes.”
Superman rubbed a hand over his face. “Bruce—”
“You asked why I don’t train the League,” Batman continued. “Because you refuse to listen.”
“And the Titans do?” Hawkgirl asked skeptically.
“No,” Batman admitted. “But Robin makes them.”
—
The Titans arrived thirty minutes later.
16 year old Robin walked into the training room carrying coffee for half the League like this was a casual social visit and
not a direct challenge to the world’s greatest heroes.
“B said you guys were struggling with teamwork,” he said cheerfully.
Flash immediately pointed accusingly. “See? That. That attitude right there.”
Robin grinned. “You say that like I’m wrong.”
Behind him, the rest of the Titans spread out through the room automatically.
Donna greeted Wonder Woman with a hug before immediately moving toward the tactical screens.
Wally stole one of Batman’s protein bars and escaped before Batman could stop him.
Roy sat backwards in a chair and propped his boots on the table despite Green Arrow’s immediate objections.
Garth quietly began reviewing the previous simulation footage.
No one told them where to go.
No one assigned tasks.
They just… moved.
Like a machine that already knew how every piece fit together.
Batman activated the simulator.
“Standard extraction scenario,” he said. “League versus Titans.”
Hal laughed immediately. “Oh this is gonna be embarrassing.”
“It usually is,” Robin agreed.
The League took that as confidence.
They would later realize it had been a warning.
—
The simulation started.
Hostages trapped inside a collapsing high-rise.
Multiple hostile combatants.
Civilian panic.
Limited time.
The League deployed first.
Superman took aerial overwatch.
Wonder Woman coordinated civilian evacuation.
Green Lantern created containment barriers.
Flash ran perimeter control.
Textbook efficiency.
Then the Titans entered the field.
Everything changed.
Robin didn’t issue commands.
He barely spoke at all.
But the Titans moved together with frightening precision.
Wally disrupted enemy movement patterns before the League even noticed the pattern existed.
Donna redirected structural collapse zones to create evacuation corridors.
Roy eliminated sightlines and weapons placements with impossible trick shots.
Garth manipulated water pressure in the building’s damaged systems to stabilize weakening foundations.
And Robin—
Batman narrowed his eyes slightly.
Robin was controlling the battlefield.
Not physically.
Psychologically.
He moved through the simulation like he could see three steps ahead of everyone else.
A touch to Wally’s shoulder redirected the entire team formation.
A single word sent Donna changing routes before the building collapsed.
Roy fired arrows before targets appeared because Robin had already predicted where they’d move.
The League fought like experienced heroes.
The Titans fought like they shared one brain across five bodies.
The simulation ended in four minutes.
The Titans had evacuated every civilian.
The League had lost half the hostages.
Silence filled the training room.
Then Flash frowned.
“Okay,” he said carefully. “Again.”
—
They lost the second round too.
And the third.
And the fourth.
Different scenarios.
Different terrain.
Different opponents.
The result never changed.
The Titans adapted faster.
Communicated better.
Covered weaknesses before they became problems.
At one point Superman changed tactics mid-simulation only for Robin to counter the adjustment before Clark had fully
committed to it.
“How did you know I was going to do that?” Superman asked afterward.
Robin blinked. “You always do that.”
Clark frowned. “No I don’t.”
“You favor left-side pressure when civilians are involved because you subconsciously prioritize visibility and crowd
reassurance,” Robin replied casually. “You’ve done it since 2009.”
The room went very quiet.
Batman looked unsurprised.
“Dick profiles teammates obsessively,” he explained.
Robin shrugged. “It’s useful.”
“It’s terrifying,” Hal corrected.
Wally snorted loudly. “Oh, you guys haven’t even gotten to the scary part yet.”
—
The scary part turned out to be the training.
The League made the mistake of asking.
Specifically, Green Arrow made the mistake of asking.
“So what exactly is Robin teaching you people?”
Roy immediately answered.
“Trauma responses, tactical coordination, emergency medicine, psychological profiling, six styles of hand-to-hand combat, and advanced trust exercises.”
Green Arrow stared.
“…What?”
Robin smiled pleasantly. “We also do movie nights.”
Batman activated another screen.
Training footage appeared.
The League watched ten-year-old Dick Grayson running rooftop pursuit drills in the rain.
Then twelve-year-old Donna learning battlefield triage.
Then Roy shooting blindfolded while Wally deliberately distracted him.
Then Garth practicing combat in total darkness.
Every exercise built trust.
Coordination.
Instinct.
The Titans trained constantly.
Not because Batman forced them to.
Because Robin had taken everything Batman taught him and rebuilt it into something meant for teams instead of soldiers.
Wonder Woman watched Donna anticipate Wally’s movement before he’d fully shifted direction.
“That level of trust…” she murmured.
“Is intentional,” Batman replied.
The footage changed again.
A younger Robin stood in the center of the training room surrounded by the Titans.
“Again,” twelve-year-old Dick ordered.
Roy groaned. “We’ve done this like fifty times.”
“You’ll do it fifty more.”
“That’s excessive.”
“No,” Robin corrected calmly. “Excessive is dying because you hesitated.”
The League fell silent.
Because little Robin sounded exactly like Batman.
Except somehow warmer.
Less cold.
Still terrifying.
But built around protection instead of paranoia.
Batman watched the footage with unreadable eyes.
“He improved my methods,” he admitted quietly.
That got everyone’s attention.
Batman did not praise easily.
At all.
Robin looked horrified. “B, you can’t just say things like that out loud.”
“You earned it.”
“That’s worse.”
Wally burst into helpless laughter.
—
The League started noticing things after that.
Tiny things.
Like how the Titans never interrupted each other accidentally.
How they moved around crowded spaces without colliding once.
How they tracked civilian locations automatically during conversations.
How every Titan unconsciously positioned themselves between danger and everyone else.
The most unsettling part?
Robin managed all of it while acting completely harmless.
He joked constantly.
Smiled easily.
Flirted with reporters.
Played video games with Wally during downtime.
And then the moment a mission started—
Everything about him sharpened.
Not colder.
Just focused.
Like a switch flipping.
Batman saw it happen during the next emergency.
A metahuman attack downtown.
League deployed immediately.
The Titans arrived three minutes later.
Robin took one look at the battlefield and started issuing orders before anyone else had fully assessed the situation.
“Donna, eastern evacuation route.”
“On it.”
“Wally, clear airspace.”
“Already moving.”
“Roy, third building, sniper.”
Arrow already fired.
“Garth, infrastructure support.”
Water surged through fractured pipes before the building could collapse.
No hesitation.
No confusion.
No wasted motion.
The League adjusted around them instinctively.
Because the Titans created order everywhere they went.
The battle ended in under twenty minutes.
Afterward, while emergency crews swarmed the streets, Flash stared openly at the younger team.
“You guys fight like Batman.”
“No,” Wally said immediately.
Robin grinned tiredly.
“We fight like each other.”
And somehow that answer was infinitely more intimidating.
—
Later that night, after the Titans had left, the League gathered in the Watchtower briefing room again.
No one spoke for a long moment.
Finally Superman leaned back in his chair.
“Well,” he admitted slowly, “that was humbling.”
“Terrifying,” Hal corrected.
Batman said nothing.
Wonder Woman studied him carefully.
“You knew.”
“Yes.”
“And you let us underestimate them.”
Batman looked almost smug.
“You assumed they were children because they laughed.”
The room fell silent again.
Because he was right.
The Titans joked.
They teased each other.
They acted young.
But underneath all of that was nearly a decade of relentless training, absolute trust, and battlefield experience most adult heroes couldn’t match.
They weren’t reckless kids playing hero.
They were veterans.
And suddenly the League understood something deeply unsettling.
If Batman had built Robin into this—
And Robin had trained the Titans—
Then the most dangerous team on Earth might not actually be the Justice League at all.
