Author's note: it's 2am and I'm writing a fanfic so don't please mind my grammar and mistakes.. anyway class 3-A does what other third years do but one day they got hit by a time travel quirk. How will their younger selves react to everything that has changed, new relationships, new everything

Ships (every ship is valid these are just the ones that I like) : kiribaku, todomomo, Kaminari x Jirou or Shinsou I haven't decided yet

Aizawa calls his students outside. They know that it's going to be just one more training day, just one more simple lesson about villain fighting...

At least that's what they thought.

Everybody's outside, just chatting, getting ready for the class, and then, BOOM

A bright light appears out of nowhere, and disappeares just as quickly, and there is 9 people,just standing there, looking almost as shocked as class 1-A was.

Everyone's first thought was "we've been attacked, oh no, oh shit" and while Bakugo is getting ready to attack, Midoriya noticed that something was off... really off. These people look SO MUCH like them. He remembers Toga's quirk and starts mumbling about who these people might be. Now Bakugo is already attacking.

He attacked the guy who looked incredibly similar to Todoroki who dodged his attack like it was nothing and threw him at the other end of the training ground.

Then one of the strangers, the red haired guy, starts talking

"HEY HEY, be careful, we don't mean no harm, but oh shit are you guys real?"

"Yeah very real, and we REALLY are going to beat ur villain-asses" said Bakugo who was now already back and ready to strike again.

"Villains? Wait u r talking about us right? HAHAHAH we aren't villains, but I gotta ask what year is it?"

The read-haired guy who was the spitting image of Kirishima spoke again

"2019. And if u aren't villains than u need to prove it. And explain why are you here." Said Aizawa Sensei who seemed to ignore the outside appearance of the strangers.

Instead of doing as they are told to, they start talking to each other

"There is no way that that villains quirk worked"

"Maybe it's just an illusion"

"No way, guys, I think it's real"

"Well whatever it is we have to figure out how to get out of here"

Aizawa was starting to get angry "And where do you think you are going?!"

"O-oh we are so sorry for the miss understanding!" The tall green haired boy stepped up "Listen we are actually... how do I say this... ugh what about the butterfly effect... ughh..UGHh"

"You know what, screw the butterflies" said the blonde stranger, and pulled out something that looked like a hero license? But there is no way...

on the license was written:

Bakugou Katsuki

U.A. high 3rd year

Ground Zero

"HEY THAT'S A FAKE HOW DARE YOU USE MY NAME YOU EXTRA" shouted the 1A's Bakugou who was, in truth, really confused.

The green haired boy starts talking again:

"Okay there's no going back now...

Listen we fought with a not so dangerous villain, at least we thought so... then he starts blabbering about sending us all back in time and, we didn't believe him because, we didn't think it's possible that such a random villain has a such a dangerous quirk...

So long story short... we are from the future, yes we are class 3-A, it's great to see you all again"

"WHAAT??"

"You guys are lying"

"But they do look a lot like us"

"What are we going to do??

"What if they really are from future?"

"I choose to trust you" said Aizawa and everyone was in great shock "Maybe because that license is too hard to fake, it has a special code, and that, right now there's no quirk complex enough to fake all of this... I'll bring you to principal Nedzu he will know what to do" he said calmly"And you" now talking to his students "You go inside the dorms... I'll inform you about everything later"

~an hour or so later~

Class 1-A is in the common room, still discussing what happens earlier that day and suddenly, the ten strangers walk into the common room

"Hi soo... they found out that we aren't villains and we will have to stay here until we figure out a way to go back to our time.. then Shinsou will use his mind control quirk to make you forget what you saw and prevent the butterfly effect and paradox and what not... so I guess we are straying together till than right?" Said what now they knew was the older Kirishima with a big smile on his face...

Now class 1-A knew who they were... the 8 strangers: Bakugo, Midoriya, Momo, Jirou, Shinsou, Kaminari, Kirishima, Uraraka and Todoroki.

Who knew he'd be this tall.. and he looked kind of... stronger? Might be because of the scars that he had now, and his hair was also visibly longer.

The class 3-A started making themselves at home just casually sitting wherever they found a place to sit..

"Wow this place sure didn't change a lot don't you think guys?" Said the older kaminari, who, surprisingly didn't change a lot, his hair was a bit short her almost invisibly shorter his height was the same but he also did have a few new scars that looked like burn marks

"Yeah but it does bring back memories" Said Momo whosehair was longer, face more matured and she was as pretty as before

The younger class started noticing all the changes on them selves with the biggest ones being Bakugo's and Midoriya's

Bakugo now has a side cut that couldn't suit him better, he had a big scar on his chin and he looked overall more buffed and was somehow.. calmer

Midoriya was now one of the tallest people of the group, for sure taller than Bakugou who was now shorter than Kirishima too and he didn't look just.. umm.. like a broccoli anymore? His face was A LOT more matured and his overall complexion was just somehow tied together by it. He had a lot of scars on his arms.. nothing new.. looks like he kept breaking them a bit longer.

Todoroki was also really tall, and although his face was serious as usual, his movements were just a bit more... I guess you could say.. lively.

And so the list of changes goes on...

The youger teens wee just staring.. like they didn't believe what's going on.. and staring more and more till Mina spoke up

" So you are going to erase our memories huh... well why not make the most of it! Tell us EVERYTHING about the future!!"

"Well that's not a bad idea I guess" said the future Jirou

"Ok what do you guys wanna know first?" Says the future Deku

Bakugou grins " who is the strongest among you?"

His future self laughs, honestly laughs, like Bakugou doesn't laugh "what's going on is that really bakugo" everyone thinks.

"Listen kid it's not all about winning, you can loose too you know? But I can inform you very well that you are one of the strongest don't worry... But right now we aren't fighting for the title of the strongest or the best cause that would be too fucking dangerous, and just cause you are annoying, know that you. are. weak. too." the older bakugo was saying calmly and everyone's jaw just dropped to the floor.

"What did you say you old brat?!"

"I said you are weak too you know" and than he smirked and started shouting in a teasing voice "LOK GUYS IM BAKUGOU KATSUKI AND IM WEAK! I CAN LOOSE A FIGHT OR TWO! DOESNT MATTER!"

the older teens laughed but the youger ones wee actually kind of scared.

"Ha just kidding, at the end of the day you have to win in order to save right?" Said older bakugo again and then say down again and that left everyone thinking.

"Okay what do you wanna know next?" Said older kaminari like nothing just happened.

Mina slams her hand on the table with a serious and dangerous look on her face "couples."

"Yeah there is no way that all of you are still single!" Cheered hagurake.

"Oh shit they are right!" Said older kaminari

"Oh my gosh they don't know..." said older kirishima

"This is gonna be exciting" older Momo smiled and than stood up.
