High On Heroism (BNHA/MHA OC)

To Quell The Carnage Pt 1

"Hosu you say?" Sir Nighteye questioned.

Toki nodded, saying "I'm worried.... I think Tensei's little brother might try and go after the hero killer.... And um...."

"Bouran?"

Toki winced, saying "How did you know?"

Mirai sighed.

"Look.... There might be a way to contain Bouran. But you and her won't like it, especially since we don't know why she's going after Stain."

Feza received a text message on his phone, Hawks looking over at him.

"Everything alright?" The hero questioned.

Feza stared at the text, saying "I need to fly and help my friend out. Is that okay?"

Hawks shrugged, seeing Tokoyami struggle to keep up with them.

"Go ahead! You're fast enough to be there and back anyways!"

*A couple days later....*

Hosu was in absolute chaos. Nomu were out on the streets. And where was Tenya Iida, you might be wondering?

"You're just here for vengeance? Pathetic."

He was currently staring at the hero killer.

"I'm here for more than just vengeance.... I'm going to make you regret what you did to my brother, Ingenium!"

That's when he lurched forward, a burning pain in his abdomen. What was this?!

"Oh, how unfortunate.... Guess you really aren't able to handle my power."

A dark red substance covered his body, this hero suit becoming a dark black color. Stain watched as his engines appeared to warp into more jagged forms, his helmet rising to cover his head once more. His armour became a black with red spikes sticking out of it, and the mouth of his helmet warped, becoming a sharp and jagged maw.

"S- Stain.... Kill, STAIN!"

"You're rather foolish, Ingenium...." Stain muttered.

"I, AM NOT INGENIUM! I, AM CHAOS!!!!"

With that, the crazed student ran at Stain, sending a kick into his chest, red flames jetting from his engine calves. Stain used his sword to slow himself to a stop, throwing a few knives and daggers at the student. Before they connected, Iida was tackled to the side by a green blur.

"IIDA!" Midoriya screamed, trying to get him to focus.

When he looked back, Stain was gone.

"You.... You let him get away!" Tenya snarled.

Midoriya took a few steps back, saying "Hey, what's going on with you?! The Iida I know isn't like this! You need help!"

Tenya glared, hissing at him, saying "I don't need help! I'm the hero! You.... You're acting as of I'm the problem!"

"What?! No, that's not true at all! You're Tenya Iida! The class prez! You're not like this! We have to get that.... That thing off of you! It's making you act crazy!" Midoriya said, trying to get him to calm down.

For a moment, he seemed to be in pain, struggling. The weird darkness around his face receded.

"M.... Midoriya.... Help! I can't get it off!"

It covered his face again, and he spoke with more aggression and rage.

"No! I need this power! I will kill Stain, even if I have to tear through you!"
