The Boom

He didn't have to even have to walk out of the training facility to know what score was awaiting him on the other side. He didn't have to, but then again there were lots of things over the years that people had tried to argue with Katsuki that he didn't need to do. And he took a lot of pride in doing them anyway.

So, without warning, he blew open the door with a punch of his fist, sending the thick metal frame flying toward his awaiting classmates and evaluators.

The wimps, they actually still screamed and yelled at the big booms. Like it mattered at all. Idiots.

They had all been at UA for years now and they were all on track to becoming the next rising stars of superhero enforcers of the land. And, beyond that, they had all been in Class 1A with Bakugou for ages. They should have known what to expect.

The kids that mattered did, of course. As flippantly as they might have been regarded by Katsuki in a glance, he knew who was going to act before they acted because he did more than sit in the back of the class with his legs propped up.

Class President and constant stickler Iida used his enhanced speed to move aside the more vulnerable underlings with a dash. Deck, for all his theatrical wide eyed shock, moved quickly and punched up on the door with calculated efficiency, sending it out of the direction of any bystanders. Uraraka, always proving herself with that extra step, levitated herself before tapping the underside of the door, slowing its momentum almost immediately.

And then that damned showoff, Todoroki, froze a block of ice upward, catching and securing the already slowed door as he did.

Because of course those ones did. Bakugou expected no different.

Just as it was completely expected for Kirishima, the one student who hadn't moved at all despite being in the pathway of the door, smacked himself in his hardened forehead and let out a prolonged and tired groan. "Katsuki," he mumbled.

There was a touch of annoyance and perhaps some regret with how Kirishima reacted, but Katsuki was ignoring it for the moment in favor of looking right at that disappointed and soured look on Deku's face. It was easier to be annoyed with and rage at. He was just so—

"Don't give me that look, Deku!" he roared.

"Bakugou!" the instructor finally yelled. "Ignoring the destruction of school property, you had the shortest time record on this course of anyone in your class. But you missed the objective by destroying the room it was in. That is unacceptable for this rescue course and as such you will not pass this one and will be required to retry at the end of the week."

Gritting his teeth, for reasons beyond him, Katsuki did not fire back. He didn't remind the instructor that his power was to explode. He did not remind them all that the time limit on the course in question made simple recon near impossible in his over encumbered costume design. He did not counter with the fact that he didn't have the analytical skills of a Deku or the patience of a Kirishima.

He didn't point out that his temper once ran as hot as his explosions, that improvement had been made.

He snarled and scoffed, putting his fists into the pockets of his pants.

"I'll blow that one too," he snarled fiercely instead, and went back to wait for the next student to pass.

He would watch the screens, see how the others beat the course where he couldn't. It was a pattern, judging by his face, that Deku had surely noticed like the creeping observer in Katsuki's life that he was.

The instructors shouldn't put Katsuki first on a course. His ingenuity came from besting others.

It was, after all, something he had learned from Deku.
