3rd Person PoV

Kirishima grabbed his PE kit and ran to catch up with the rest of the group, scanning for Bakugou. Instead, he found Midoriya, who was meant to be with the blonde but apparently wasn't. Kirishima turned back around and realised Bakugou was behind him and he stopped and waited for him to catch up.

"Hey dude!" The redhead lifted up his hand for a high five but the explosive boy walked away. Kirishima slowly lowered his hand, feeling slightly humiliated. He mentally shook himself and ran to Bakugou.

"Yo man, what happened with Midoriya? How do you even know who he is?" Kirishima tried to start conversation with him, he also really badly wanted to know the answer. Bakugou stiffened and faced away. The redhead tried to get his attention by waving his hand until Bakugou sighed with annoyance.

"Just some fucking wannabe I went to Junior High with." He grumbled, Kirishima nodded and waited for him to continue. Bakugou huffed and rolled his eyes.

"He was a weak, useless, quirkless nerd." Bakugou said in a mixture of rage and confusion. He looked at the green haired boy spitefully. "I don't understand how he got here."

"Quirkless?" Kirishima asked, extremely confused. "He's far from it! He's one of our most powerful students, if not the most powerful!" Bakugou looked Kirishima in the eye and wondered whether he was joking, he realised the redhead was serious.

"That doesn't make any sense..." Bakugou's voice trailed off.

----oOo----

"Are you all in your pairs?" Aizawa asked lazily, scanning the crowd. Everyone seemed to be, other than Midoriya and Bakugou who were standing 6 metres apart." The teacher gestured at them to move closer to each other, Midoriya took a nervous step toward the blonde, and Bakugou took an angry step away. Aizawa wanted to facepalm but couldn't be bothered.

"Today, we'll be sparring as usual." The teacher yelled above the students chattering. "This time, I don't want to catch anyone in Recovery Girl's office." He glared at a certain green haired boy. Izuku looked nervously at Bakugou then shrugged at the teacher, who huffed in response.

"Begin!" He called out.

Bakugou crossed his arms angrily and stayed where he was. He didn't feel like being his Junior High self and definitely didn't feel like getting expelled again. Not since he met a specific redhead, but obviously because his mom would kill him. Obviously not to do with the redhead. At all. No sir.

Midoriya seemed desperate to get Bakugou to spar with him as he wanted to improve and become the number one hero, Bakugou didn't care as much. Sure, he still wanted to become the number one hero but not if he went back to being a bully. He'd had enough experience with bullies.

"Please, Kacchan! We need to train!" The green haired boy pleaded, Bakugou breathed heavily out of his nose and looked away. Midoriya scooted around so he was in front of the blonde again, but he huffed and turned again.

"Listen, Kacchan." Midoriya crossed his arms, immitating Bakugou. "If you don't started doing something soon, I'll call Aizawa. He won't be too happy that one of his students are slacking off, maybe he'd have you expelled. I'm sure your mom won't be happy trying to find a new school for you." Izuku taunted. Bakugou snarled and spun round to the green haired boy. He'd changed drastically since the last time Bakugou had seen him.

"What was that you dumb nerd?!" He ran at the smaller boy, swinging his right hand at him. Izuku dodged easily. This seemed to enrage Bakugou further and he swung his left instead and almost caught Midoriya's face but the boy ducked. Bakugou growled.

"Kacchan, have you not changed since Junior High?" The freckled boy grinned, it reminded Bakugou of his own grin. It was unsettling to see it on the other boy. "Luckily for me, I have." He activated his quirk and punched Bakugou in the stomach, the blonde almost flew back but managed to keep his feet firmly planted on the ground.

Bakugou coughed into his fist, he brought back his hand to find red spots of blood. He turned back to find the green haired boy but he was gone.

Suddenly, Bakugou felt something slamming into his back and spun. Deku was there, still with that smirk all over his face. The sight filled Bakugou with so much rage he couldn't contain it all any longer, huge explosions burst from his exposed skin. To his satisfaction, he heard the green haired boy's grunt of pain.

He turned his body to face his fellow student and got into a fighting stance. Deku did the same. They ran at each other, Deku beginning to be covered in glowing lines showing his quirk, Bakugou was releasing huge explosions.

Simultaneously, their fists hit each others' face and they flew backwards, Bakugou's head hitting the ground beneath him and Deku's back hit a metal pole behind him. All students who were watching rushed forward and others called for a teacher. Both boys who had been included in the battle had passed out or were close to doing so.

Only one though swarmed Bakugou's mind as he fell into unconsciousness:
Well shit.

This be the author. Sorry about that, I have no idea how to write battle scenes.
