What if Deku became a villain

Chapter 8

-With the UA students at the USJ-

Katsuki watched with his usual scowl as the pro-hero Thirteen, who was serving as a guest teacher in the class's visit to USJ. He glanced around at the large dome building and narrowed his eyes. Ever since the Quirk assessment, he felt like someone was watching the class. He initially dismissed it as the same paranoia that made him think he saw Deku on the street that first day. Now, though, he was getting the same feeling—stronger than the other times he felt over the past days.

The other students were hyper but still listening intently to what Thirteen had to say. A few weren't as impressed by the speech, but Katsuki only really noticed that Todoroki was glancing at him and looking around the building with similar caution. He didn't know enough about the other, who he'd nicknamed Half'n'Half, but he recognized that the other seemed to feel like something was observing them, too. It was probably a good thing, a sign that he wasn't completely crazy. Katsuki had tried to mention it to one of the other students he found tolerable, Kirishima, but the red head just said he was probably nervous since he was in a dangerous environment. The blonde knew that wasn't right, or denied it.

Katsuki was about to give up on his paranoia when he finally saw something. A black purple swirl of darkness near the fountain in the center of the USJ building. He glanced at Todoroki, who was looking at the fountain, too. Their teachers noticed it soon after him and the other, and then soon the rest of the class. They all watched, murmurs and shouts of fear spreading in the small crowd of students. Katsuki grit his teeth, slight satisfaction flashing in his mind at the prospect that he was right. He immediately mentally shook that thought off and watched as the swirl grew.

Then, people started walking out of the swirl. Two yellow eye-shapes appeared on the dark smokey swirl as what Katsuki guessed were the last people walked out. The smoke pulled back a bit, until it was a sort of moderate size. He immediately looked at the other two standing next to the smoke—who he was guess was probably a person. Without realizing it, he was tuning out the voices of the teachers and students.

His eyes widened a bit at the green hair he spotted on one of the two near the smoke-man. A mask covered the bottom half of the person's face, but their face was tilted up, looking right at the students with shining green eyes. Katsuki couldn't ignore the pang of recognition in his mind. He really tried to, though. There's no way, echoed in his mind over and over. He vaguely heard the person was a villain in the back of his mind that was playing attention to what was happening around him. He tried to look at the other villains, but he couldn't get the feeling to stop and kept looking back at the green-haired villain. He thought of other things that could stop his suspicion. He was a hero nerd, so no... But then again...

Katsuki's hands sparked small explosions as he grit his teeth even harder at the thought that it might be who he thought it was. To the other students, the explosions passed off as him wanting to fight, but he wasn't even listening as Kirishima tried to calm him down. He kept his eyes on the green-haired villain as they turned away slightly, seeming to talk to the gray haired one next to him.

The smoke shifted again, moving over the green-haired villain before going back into it's previous position. Katsuki's breath hitched as he stared where the other had been.

"A warp quirk!" he heard some else say.

He immediately looked around for the green-haired villain, or a flicker of purple-black smoke to signal where they'd appear. Todoroki was looking around, too, having the same idea that they might appear and attack near them.
