Okay so because the author in me doesn't know how to fucking chill for thirty minutes have half a novel I guess, but summed up in Crackhead.
So pretty much for some context on this AU, Izuku "Rat coon" Midoriya is a quirkless villain for funzies. 100% he's gay for Bk, and steals his shit because he's just a bastard rat man who lives in a shwanky run down van hidden in the middle of a pile of garbage. Also bc he wants to see how long it takes for Bakugou to notice his shit is missing, and he wants something that smells like the crush. 200% feral man. Outruns Aizawa and Police many times until Aizawa finally captures him and he becomes Nedzu's pet project(consensually, it was doing a stupid rehab program or going to jail. He wasn't going to jail any time soon.)
First day with Rat coon in class
Aizawa:Hello class, listen up, Nedzu has a new pet project and decided that I didn't have enough of you little shits to look after so meet your new "classmate". Problem child you can come in now.
Izuku: Just kinda fucking, strides into the room???? Not even five minutes in and his uniform is in shambles, tie is tied like a noose, shirt sleeves are rolled up to elbows, jacket tied around waist, pant leg cuffs covering the heels of his shoes, his face is covered in piercings, he has a nose ring, an eyebrow split in three places with two rings in it, an eyebrow with one piercing in it, top and bottom snake bites, uneven earrings in his ears. Iida has a brain aneurysm. Bakugou just stops entirely, this is the kid that he grew up with, he looks like he doesn't want to be here, this isn't the same hero loving boy he remembered.
Izuku: I'm Izuku Midoriya, but you can call me Rat coon. I'm a villain, or was a villain? The details on that are a little unclear. I'm Nedzu's little pet project, and let me make this clear, I'm quirkless and would rather die than be a hero, but it was this or dropping the soap on the first day for fun. No you may not ask me any questions, yes i have self preservation skills I just choose to ignore them, if you even think for a minute that what you're asking me to do is a joke I will do it. I once tried to jump off a roof to kill myself upon the instructions of one of your lovely classmates and failed, I hit a tree and broke four ribs.
Bakugou: You did... what?!
Izuku: Oh, hey Kacchan! Yeah, I tried to die and instead hit the dumpster like the quirkless idiot I am. Trust me, I stopped wanting to be a hero a very long time ago, I was just tired of everything. Fun fact, my ribs did heal but somewhat crooked and I'm pretty sure one is still floating around. Whoops, oh well.
Bakugou: Why didn't you go to the fucking hospital!
Izuku: YOU'LL NEVER TAKE ME ALIVE! *proceeds to jump over the podium, roll through the open door way, and leap over a railing to the bottom floor*
Aizawa: I don't get paid enough for this
That was the day class 1-a had the assignment of catching the batshit wild hooligan running around. What they thought was an easy assignment took all of them trying to corner Izuku the class periods of training for the next two weeks(Aizawa knew where his favorite type of spots to hide were, so he'd retrieve him for lunch and other classes)
Izuku: *eating some volatile concoction of moldy food drowned in random condiments*
Aizawa: You know you can eat something more edible, right?
Izuku: W-what? ???????? But this is edible??
Kirishima: Oh hey Midoriya, want to help us mess with Bakugou?
Izuku: Bold of you to assume I would even say no.
