It was a normal day for class 1A as they were taking in the notes from their teacher, Aizawa also known as Eraser Head. Some were paying more attention than others, but everyone was writing down the words in the chalkboard.

"... So when in a situation like this, you need to evaluate your surroundings to make sure a new threat could not emerge as you take care of the civilian casualties" he explained in a monotone voice, charisma wasn't really one of his strongest points so he came out as disinterest in the subject as the rest of the class

"Ugh!... How boring!" A voice exclaimed loudly to the whole class, which made them look around for who said it but no one could quite recognize the voice, Aizawa however just assumed one of his students are being a trouble maker and not giving the course its necessary attention. But even he had trouble telling who it was, or if the voice had actually come from their room

"I didn't expect a school for super heroes to be so disappointing" the voice once again spoke and now some students were concenerd, was this a villain attack? Was another class playing some trick on them or were the students actually imagining this

"Alright, you better show yourself before I am forced to." The teacher threaten as he actives his quirk, trying to scan the room for whoever is hiding in their presence with whatever Quirk they possessed, but the students notice the words in the chalkboard move and contort into a bizarre drawing of... A costume wearing imp?

"If you want to learn how to be a hero, you need to do it from the best" the drawing said as he caught the entire classroom's attention, Aizawa tried to erase whatever quirk he was using but nothing happened. The chalkboard imp snapped his fingers and a cloud of smoke appears drawn in his place, meanwhile a 3D version in full color appears by the side of Izuku and before anyone can react, he claps his hands causing everyone to disappear from the room.

"First part, done!" He risked a checkmark in a list he spawned in the middle of the air, the following checkmark was written "get All Might" and the other checkmarks were various different individuals from MHA.

"Yeah... I don't know half of these people, nor do I care. Already got the main class so they should be enough for now, but let's get the big shot hero for good measure" he tossed the list out as it becomes a bunch of bubbles, he cracked his fingers before clearing his throat.

"If I want to bring someone else, I can do it later anyway and it will be like they always were there" he blinked to... Someone, before disappearing from the class room altogether.

"What happened?" Izuku asked as they were disoriented for a second, but now he and his classmates found themselves in... A cinema? Seemed like a fancy theater that had been converted into one at least, the class was confused and Kirishima was trying to force the door to open but they were sealed shut.

"Is this a villain attack? Like in the USJ?" Uraraka asked the green haired boy as they observed how there was no villain around here, nor were they retrained by chains or something. Could still be a trap however, none of them could be sure

"I... Honestly can't tell" Izuku responded as he was also lost, some of their classmates were trying to see some other way out, like Bakugou trying to explode the doors open to no avail or Mina using her acid. But nothing they did seem to work, until they hear a poof of smoke as a confused All Might appeared in the theater as well

"What?... Where did I..." He noticed the class as they rushed in to ask for his help, but even the number one hero was confused as for a moment he was in his office when suddenly- their cut off by a bunch of noise from what sounded like a triumphant quartet play as if they were to announce something

"Welcome hero wannabes, get ready for the show of your life with your host..." A voice said before a poof of smoke and confetti explodes in the air

"Bat-Mite! Ready to watch the greatest hero ever made? Because that's what we will be doing right now!" The imp proudly proclaims as he appears in the confusion of everyone, from his bizarre look to the entire situation they were in, but the first thing that they all thought was... What the fuck was happening?

[Author's notes]

Happy new year! To start off 2025 I am going to be giving you all a new fic, that is different from my previous works

I'm terrible at writing beginnings so this is the best I could come up with, will be updating this chapter in the future but if you're reading this you might already know what a react fic is.

For those who don't know, in this fic I will have the characters from MHA react to BTAS and try to make the best version of this as I can, feedback is always welcomed and is encouraged since these will take a while to write, so your support is heavily required for the future of this fic
