Chapter Text
Y/N POV.
It is a beautiful day outside, flowers were blooming, birds are singing on days like this, teens like me should be outside with friends so it's no surprise I was out in waterfall having a picnic with Sans. I was about to tell him my biggest secret, after all, he's done for me he deserves to know that I'm not a regular human but was part human part wolf. I was extremely nervous about telling him considering how he reacts to Frisk resetting.
Then I heard a sound like static, and a whoosh as blue strings fly at Sans from a glitching white portal. I instinctively jumped in between Sans and the strings. When they hit me my soul appears in its usual f/c and s/f/c. Then a skeleton that looked like Sans but with a black skull with yellow teeth, red legs and fingers with yellow fingertips they wore a red shirt, black shorts with two blue lines on them, a black jacket with blue fur and yellow drawstrings and they wore black fingerless gloves. Their eye sockets were red with the left eye only being a yellow pinprick and the right being a yellow circle with a blue inner circle. The weirdest thing about him was the fact that he was glitching with error signs around him.
Then Sans hearing me yelp in surprise turns to the newcomer and shouts "GO AWAY AND LEAVE US ALONE ERROR." Then Error tightens the strings around my soul and says, "not while this glitch is within my strings." He was surprised when a gaster blaster appeared and broke his strings. Sans then yelled at me to run while summoning more blasters to shoot at Error. I broke into a run and sprinted into the next room while Error and Sans were fighting once I was well out of their sight range I transformed into my wolf form which is larger than a regular wolf by about a metre and had h/c (hair colour) fur before turning around and running back to help Sans.
When I got back to where they were fighting I was surprised to see that Error was shooting strings out of his fingers to attack Sans who was on the offensive and only occasionally landing a hit on Error which did almost nothing. I snuck around the edges of the room having to dodge attacks coming from both of them as they performed their deadly dance. once getting behind Error I leapt upon him attacking him with my claws and then retreating to dodge his attacks. While I was attacking Error, Sans was charging up a blaster to hit him from behind. Just as Sans fired Error teleported behind me and caught me in his string pulling out my soul once again but this time it had a grey and h/c aura around it, then for a moment both him and Sans looked shocked before Error tightened his string around my soul forcing me to transform back into my thankfully clothed human form.
Then Error said, "well, well, well your not just a human are you but a shapeshifter, aren't ya." "So what if I am," I replied angerly. There was an awkward silence before Sans broke it by saying " wait you're a shapeshifter and never thought to tell me, I thought we were friends." " I was just about to when he came and started this-this mess," I replied after a moment. then Error said"drama," then both I and Sans relies with "shut it Error." Then Error says "I'm going to go with this glitch here if you or anyone try to stop me I'll shatter her soul." Before knocking me out and opening a portal.
