By the way this story is a total crack fic, Jay's abilities are extremely OP but he's both lazy and forgetful so at the end of the day it doesn't cross his mind until he needs to.

Jay watched unseen as his class filled up, he was actually just sitting behind the board, he'd had a small 2m by 2m room with a bean bag and a camera showing what was happening in the classroom so he just sat watching whilst also thinking of ways to screw with his students. He saw as Tenya, as tight an ass as ever was yelling at Bakugo for putting his feet on the table and Todoroki and Tokoyami sat with cold attitudes facing straight forward and as the class filled he took the side exit and appeared out where it appeared to be a plain wall, the class immediately recognised him as the man from the entrance exams "Well good morning"

Some mumbled a response but the engine quirk boy responded like he was an army soldier, he smiled and pointed at the boy "Aha, I got you, the only one who'd choose to wholeheartedly respond to the greetings of a teacher is a total dork or a teacher's pet" Iida looked ashamed and bent down in apology "See! Loosen up a bit, Okay now we'll start the day with..." He noticed the disturbance he been prepared for and saw purple ball boy has stuck Momo to her chair and was reaching to touch her chest. Jay leaped forward and sent a kick to the boy's head sending him flying out the window, he jumped at rocket speed to catch the boy by the neck and bring him back holding him in front of the class "Let this be a warning and lesson to you all, kid you illegally used your quirk and also attempted sexual assault so your gonna have a couple decades in prison to make up for it also you'll be of course expelled from U.A"

The girls whilst thinking that was a terrifying punishment they were also quite glad, they'd been quite disgusted by that classmate but now he was gone. Jay then started yelling "Nezu come get this guy and bring me a new student" A minute later Aizawa walked over with an equally tired looking student, picked up sticky boy and left.

"I asked for new student not your so..." The man's favourite capture tool flew out and covered his mouth before he could finish but Jay just took it off "Fine you flea ridden bastard, Okay new student introduce yourself"

"Hitoshi Shinso"

"Nice now next order of business... Nezu throw the fire bastard in hell!" Ten seconds later Midoriya's phone chimed signalling a notification, he turned it on and was shocked "You wanna read that out Broccoli"

"Umm Endeavour's many crimes revealed, no trial is being giving and is going to Tartarus" A small smile appeared on Todoroki's face, he was actually beaming inside, he'd never have to deal with that man again.

With so many delays Bakugo was angry "Hurry up and start the class!" He put his hand out to cause an explosion but he just looked high as he shoved his hands around like he's in the ginyu force.

Jay smirked "It's okay if you wanna give us a little dance but tone down the volume"

"Shaddup!"

"Make me, actually let's all go outside and do some tests, If you can beat me Boom boy then I'll shut up about it all together but if I win I'm sending the video to every member of school staff"

"Fine!"

Jay jumped out the window as the rest of his class walked through the door, he waited about ten minutes and they all showed up "Word of advice, Jump out the window, it's much faster"

Kirishima looked happy "That's so manly"

"Yeah sure, now we're going to be doing the standard fitness tests but with your quirks" This got much happiness from the class, with everyone excited except a certain bastard child of a hobo "Okay we can start with grip test, I'll go first" Jay took the grip strength device in his pointer and thumb and squeezed a tiny bit causing it to shatter with a final reading of 27 tons

Kamanari and most other classmates looked awed "This looks fun" Jay glared at the boy, what he'd spent twenty years of his life doing this boy could do with ease.

"Hmm, the lowest scorer gives me their lunch money" The kids looked shocked that a teacher at U.A would randomly take their lunch money and Iida spoke up

"Sir, according to law..." Bakugo hit him away

"Thank you, Hey I've got an idea to make you stop trying to emulate your brother, here's a video of him dissing you whilst drunk" A floating T.V appeared and showed Jay and Iida Tensei sitting in a bar drinking whilst Tensei went on a drunk rant of all the things bad about his little brother, by the end of it Tenya was on the floor in tears. Maybe he took it too far.

"Okay you guys hurry up" One by they Did it and he felt sad about sparky boy, he should of just sent electricity through the reader to trick it but he didn't, a boy used extra arms or something like it to get 640kg and Izuku used 5% OFA on his hand causing the machine to get pushed up to 8 tons. Boom boy was getting closer to detonation.

"Next softball toss, Let's see" Jay aimed and fired upwards with a light toss causing the ball to leave earth's atmosphere and stay in orbit, the reader came up with infinity and the children went with Uraraka tying with him and Izuku coming second. By far the most unique though was Bakugo's method of telling the ball to die and watching it run away from the explosions"

"Sprints, ready set go" He took step and broke the sound barrier and appeared at the other side with 0.3 seconds, once again the class went with all their unique methods of speed. So much wasted potential.

By the end of all the tests Shinso was the lowest and had to pay up, Jay didn't know whether to feel bad to take morning from the foster kid but twenty bucks is twenty bucks.

After that all I lead them to an empty field "Okay we're doing some basic quirk training, first of all Rocky will be bombed continually by Dynamite to train his rock form strength" Kirishima nodded and became rock excitedly as Bakugo grumbled before screaming die and causing multiple explosions in his face. Jay led his class away "Now Sparky boy" Kamanari listened up "All you gotta Do is keeping out putting electricity at a steady pace and as you grow accustomed to that output through your body raise the power small bit" He nodded and walked off "Sparkle, I want you to do something similar in continually using a low level of your quirk before lightly raising it up to boost your tolerance, Pinky try and enhance the properties of your acid" Jay was getting annoyed by all the work "Floaty try and float heavier stuff, Money bags create more stuff even when your fat stores run dry" Jay sighed as he listed off more things for more people.

He sighed and thought about ways to improve things but then he had an absolutely glorious idea for the USJ thing, but it required a fair bit of work so instead he'd turn it into a seperate and push all his students to the brink of survival to really get their hearts pumping you know. Jay had never seen someone so scared as to when he punctured both their lungs and shattered his bones before fixing him.

Ah the good old days.

*Flash Back*

Teenage Jay sat in the U.A canteen, he was in his second year and he'd just majorly pissed off this Todoroki Enji kid. "How dare you, you feeble peasant weakling!"

Jay smirked heavily and used the boy's first name to piss him off more"Whatever do you mean Enji, isn't the reason your mad because your so many times weaker then me" The tone he spoke was so mocking it set the fiery teen off like a fire cracker.

"LET'S TAKE THIS OUTSIDE!" Flames lit up across the boy's skin

"Sure" Jay jumped out the window and was followed by a trail of flames, he quickly ran at Todoroki and stabbed his hands through his lungs and out his back and watched as the boy slowly died before grabbing him and returning the unconscious boy to full health.

That was the day no student, male or female ever again. He heard whispers of fear and wonder from all but his friends as he walked the mighty halls of U.A, as a king.

*Flash Back end*

And that's how the white creature known as Nezu took teenage Jay as a personal student but that's another story for another time and day since I'm so lazy I won't be uploading in a while.
