The superhuman society is great for some with popular quirks but not for quirkless let alone people whose quirks are seen as villainous, and that is how villains are created. (Villain Izuku, Izuku Shigaraki Dad All For One)

Time: something that means everything and nothing. Izuku knew this. He knew how important and precious it was. He knew how dangerous it could be. Yet, he still tries to change it. Izuku needs to fix his mistakes, no matter the costs. He needs to save everyone from the horrid deaths that had enveloped them. He was a hero, it was his job to save everyone he possibly could. It was his one purpose in this world and he was willing to give his life for it. So he travels back in time, but it's further back than he thought it would be. That's okay though, because maybe he can maintain his relationship with Kacchan and look after his mom better. Plus he'll have more time to form his plans. Only, it doesn't go exactly as he planned. For every different decision he makes, every new leap Izuku takes, another nightmare comes his way. He swears to save everyone he loves, no matter how many flaps a butterfly may take.

Izuku never left UA, instead, he allowed his friends to help him patrol the city and take down All For One's Lackeys. However, when he wakes up in the middle of a park, everything changes. Now he's been thrust into a time even more war-torn then his, if he doesn't learn fast, he's not gonna survive.

Just when Midoriya Izuku was forced to leave his friends to defeat the villains, he travelled two years back in time, when he was still in middle school. What will happen when Deku re-lives his life?

After being betrayed by the one he trusted most, Izuku died - and travelled back in time? Given a chance to mend his mistakes, instead of becoming a villain, a new option presented itself: becoming a hero. However, the transition between villain and hero is not as easy as it sounds... Will Izuku be able to surpass his villainous instincts?

When all Pro Heroes and Heroes in training drastically change their behavior, Izuku runs as the only one not affected. As he tries to survive, a Quirk accident reveals a startling truth and he is left to pick up the pieces.

When he was a kid, Midoriya Izuku was hit by an unknown Quirk. He was found a few days later, unharmed. He was gone for just a few days to the world, and he never told anyone where he'd been. Who would believe that he'd been sent back in time several hundred years to the Pre-Quirk Era? That he'd been adopted by a pair of circus performers who gave him the name Richard Grayson? That he, Quirkless Midoriya Izuku, had become Robin, the Boy Wonder, famed partner to the Old Hero, Batman. Yeah. Nobody was going to believe that. At least he could become a LEGAL hero, now.

Aizawa becomes increasingly suspicious of Izuku after he develops a second quirk--and one that has nothing to do with his original strength augmentation. To prove his innocence, Izuku builds up the courage to tell his teacher something he should've from the start. He tells Aizawa about the existence of One for All.
