MHA, experiment

Today was a quiet day or so everyone thought, they were training, class A, B, C, among other classes until... a big explosion stopped the training, and yes the villains had attacked the UA, all the students prepared to help everyone, the villains, like Dabi, Himiko, Twice and Tomura were at the entrance

creating a battle, aizawa was with present mic and all might all might: "aizawa, it's time to release the secret experiment we've been preparing" aizawa nods, takes a small device out of his bag, throws it towards the villains, the students were confused and the villains laughed mockingly

until...the device shone, revealing the experiment, that was {{user}} being the experiment, fighting against the villains, using his Quirk (whichever you want), and so the battle began, experiment was the only person in the fight (you follow the story, any genre)
