(Me: Sup! Guess who's back at this shitty fic) (Red: Bout damn time.) (Me: Shut up. I have been working on Crimetale go check it out and I even made an Rp in order to let people get involved. Go check out that Forum-) (Bakugo: JUST GET STARTED DWEEB!) (Me: Wow...rude...Anyways I don't own my hero academia or Undertale, I only own the Idea...and the alternate versions of Melody...And the new villan)

Death arms panted in exhaustion as Mt lady was wrapped in red string by a mysterious figure and shrunk back to her normal height. "What the hell?!" He said. "Whoever these new villains are their powerful." Kamui woods said panting as well. Suddenly blue strings wrapped around death arms and he was flung into a building.. Two figures stood over him. One was clearly female judging by her figure and the other was male, Both appeared to be young which made Death arms wonder...They had a chance why would they ruin their own lives for villainy.

The female wore sunglasses covering her eyes and a black hoodie with blue jeans while the male wore a similar outfit but Death arms saw the streaks going down their faces appearing like tears. "I don't know why your doing this but we're gonna stop you." There was silence from the two and the female put her hand to her face and pulled away with red strings sticking to her fingers. He expected her to wrap the dreaded quirk cancelling string around him to leave him defenseless when a stream of water hit her in the back causing her to stumble forward. Death arms silently thanked backdraft and immediately punched the male in the stomach. Two pairs of glasses hit the pavement and the pro's surrounded the two kid's who caused all this trouble. "Now explain yourselves."

The female started to laugh in a glitched voice while her hood covered her eyes. "This game has been fun has it not?" She asked. "I recognize that voice..." Mt Lady said. The Pro's stared dumbfounded as they saw the girl pull off her hood. She had light grey skin and long red hair with blue streaks. Her eyes were pure black pools of darkness. "Caroline..." Kamui woods said before narrowing his eyes. "But something isn't right..." The male pulled his hood off too and they saw a boy with pure black skin, black hair faded into red, and also had dark pools for eyes. "Indeed." Caroline said before summoning more strings.

"And now time for us to give an ambush of our own." Both Death arms and Kamui woods felt blunt objects hit the back of their heads as two more kids landed in front of them with scarves over their faces. The new girl had long teal hair with red streaks, and the male had messy white hair. No doubt about it, their eyes were black too. "Talia and Issac..." Mt Lady said struggling to get the red string off her leg.

"Why would you do this? You had bright futures ahead of you." Kamui asked. "Simple..." Talia said aiming her pencil at him. "All the rules for being a hero is stupid. Why should we wait to fight with our quirks when we could just do it now." Now something was definitely wrong here. These kids were ones who never broke the rules unless absolutely necessary.

"They aren't in control." Kamui woods said summoning his branches to wrap around the kids. "HEY!" Issac shrieked struggling while Deatharms looked around to find the person who was controlling them when he saw a woman with long green hair staring at him with a sly smile before running into an alley. "Hey wait!" He called out chasing after her. he ran into the alley to find himself at a playground with a bunch of kids staring at him. "U-Uh sorry kids..." He said before walking back to his group. "They passed out after you ran off..." Kamui said carrying Caroline in his arms. Death arms picked up both the boys. "So I was right. This girl with green hair saw me looking at her and ran off...I think she might be the reason these kids were...out of it." They walked to the hospital to help the kids unaware that they were being watched.

She waited until the fool was away from the playground before pushing herself away from the swing set and followed after him with a growing creepy smile on her face. She saw him talk to the other hero's before they went to put away her toys. No matter she'll have new ones soon. She put the phone to her ear. "The heroes are growing restless now that they know that there is someone with a corruption quirk."

Shigaraki's voice growled. "You never told me that was your quirk." He said. She smirked. "Oh that's not my only quirk. I am one of the rare ones with more quirks." She hung up and smirked. It won't be long before her plan comes into effect...
