First Flashpoint: UA High, day 1.

"DEKU, YOU BASTARD WHEN DID YOU GET A QUIR-"

The screaming was cut off as Bakugo was startled by being wrapped in strange fabric.

Midoriya, still cringing and waiting for impact, carefully opened one eye.

"WHAT IS THIS?! WHY CAN'T I USE MY QUIRK?"

"That would be my quirk. And these are reinforced with carbon fiber and some special alloys. Now stop moving, I'm getting dry eye." Aizawa stated all this casually while his hair floated, eyes vibrant red.

"Y-y-y-you're Eraserhead! The underground erasure hero! Ohmygodyourincidentclearingrateissohigh - "

Here Midoriya become completely unintelligible, his muttering rapidly increasing in speed.

"Midoriya!" Aizawa interjected.

"Y-yes sir!"

"While I can appreciate your intelligence gathering, we're in the middle of something."

[Canon outcome to the Quirk Assessment Test]

"Alright, everybody go back to class. You'll find your syllabi and campus maps on your desks. Go do whatever it is you must and remember" Aizawa took a second here to reactivate his quirk, making sure their attention was firmly on him. "You are all on thin ice. I will not hesitate to expel you if I see you becoming complacent. Plus Ultra. Midoriya, Bakugo, stay for a moment."

The others filed back indoors, apprehension on their faces, both for their scholastic careers and the circumstances their peers now found themselves in.

"Midoriya, take a slow lap around the track, make sure not to jostle that finger." Confused, Midoriya nevertheless complied, one hand gingerly cradling the other.

Aizawa turned now to Bakugo.

"What is wrong with you?" Bakugo was not prepared for that question, as such his only response was to stare.

Aizawa continued, rather than waiting. "I saw you jump at one of your fellow students with intent to harm with your quirk. Your quirk that is explicitly causing explosions at will. I don't know what idiocy your previous schools allowed, but that stops now. Outside of a school-sanctioned activity or in self-defense, that will never happen again. Am I understood?"

Bakugo's brain had time to reboot while Aizawa was talking, so he responded now. "But that Deku-"

"Do not refer to your classmate like that."

Bakugo was, again, flabbergasted to be cut off while he was talking by a teacher. That hadn't happened to him since his quirk came in. He gulped, a little cowed now. "Midoriya is supposed to be quirkless! He's always been quirkless! HE'S BEEN LOOKING DOWN ON ME THIS WHOLE TIME!" Once again, Bakugo found himself bound by bandages.

"Stop yelling, I'm right here. Secondly, Midoriya owes you no information. On anything. If you ask him about any information that would not endanger you to not have, he's allowed to refuse and you are not allowed to retaliate over that." He released Bakugo, the boy stumbling for a moment.

"Finally, why I'm actually using both of our time here:

You are training to be a hero. You have drive, skill, passion, and power. All exemplary traits for a hero. Unchained and indiscriminate aggression, however, is not. If you keep acting like you are, I won't hesitate to remand you to Gen Ed. Going forward, while you are in my class, you are going to keep your temper in check, your inside voice appropriate, and your conduct professional. I will not be having this conversation again."

He paused. Bakugo, completely shell-shocked, could only nod silently. "Good. Now get back to campus." Bakugo walked away, still dazed.

"Midoriya, your turn!" The verdette started, before he cringed again as the sudden movement caused a twinge in his broken finger. He stepped forward, doing his best to appear small. "Y-y-yes?"

"You jumped straight into the best way you could think of to not become a liability in battle. Good. Keep that up.

Why are you so bad with your quirk?"

Midoriya had been slowly taking a less defensive posture as his new teacher spoke, all of which reversed and then some, his previous attempt looking positively amateur in comparison.

Here, Aizawa realized he was still channeling some of his "listen or die" persona from his previous talk. He took a breath, letting some of the tension fall from his shoulders. Students like Bakugo only respected "the top dogs". That meant discipline required a heavy hand, while making sure to mix in acknowledgment to incentivize continued performance. Midoriya...was not that kind of student.

"You are not in trouble. But you're clearly struggling with this, and part of being a teacher is making sure you have resources you need. Now, your quirk. You destroyed three limbs at the entrance exams and you had to think critically to get it down to a finger. Even if you get better at a similar rate, you aren't going to graduate as a hero. You're going to graduate from Gen Ed because you've used up every single bone in your body several times over, or you're getting your diploma posthumously because you destroyed the wrong bone at a bad time.

So, again, what's the story?"

Once again, Midoriya had been straightening up, slower than before. He was almost entirely upright by the time he got the question.

"I, u-um. I've never used my quirk before?" Midoriya cringed once more, eyes closed and face turned partly away, clearly expecting a reprimand. He was instead treated to a deep, long-suffering sigh.

"This is going to be a longer conversation than I expected. Recovery Girl is already going to be furious with me for having kept you this long. Come on, we'll talk in her office."

He turned and began walking, a confused but grateful green-haired child trailing behind.

Basic info: wherever the chapter starts, assume interactions up to that point have been as they are in the anime/manga.

So, why this? I'm someone who benefited from really invested teachers. I respect the position very thoroughly, and so when I see someone abusing that title, it really sticks in my skull. It also doesn't help that most of the early anime I watched had incredible teachers.

YYH. DBZ. Ruroni Kenshin (can't really enjoy that one anymore. yeesh.).

So as you can imagine, I have beef with Kakashi, Jiraiya, and Shota Aizawa. All Might, too, I guess, but I can sort of understand his foolishness. Regardless. Where canon goes from here isn't really the point for me. If you wanna take a whack at it, go ahead, hmu with your efforts when you publish. This one won't really have many entries, unless I get inspired to explore the timelines I've put up here.

Until next time, this is your friendly Jester hero, reminding you to keep your ideals alive.
