Swan Dive Summary The Slime Villain Incident, and the events leading up to it happen one year earlier. Izuku, broken and lost in the face of All Might's words, decides to take Kacchan's advice. But a familiar Underground Hero won't let a young life end so quickly. How will a simple right-place-right time scenario change things? OR: Aizawa Shouta saves the life of Midoriya Izuku and finds himself with a new apprentice and surrounded by a quickly growing family circle. What has he gotten himself into? Heavy Dadzawa and Dadmic. Auntie Nemuri and eventual redeemed Bakugo.

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.

• ON HIATUS • Midoriya Izuku attracted trouble. It was just a fact of life - the sky was blue, the grass was green, and Izuku constantly found himself in an absurd number of deadly situations. He was okay with that. Mortal peril was an average Tuesday afternoon for a Pro Hero like him. Being kidnapped was practically a holiday. Saving civilians as a building collapsed around him was easier than facing his worried mum afterwards. He had dealt with All Might's disappointed dad stare and only cried for two hours afterwards. A serial killing villain with an unknown Quirk would be no problem! ...but even Izuku had to admit that being sent back in time to his first day at UA wasn't on the agenda. Still, there was no-one more spitefully determined than him - he was going to make the most of it. Yeah, good luck, heroes and villains alike! Deku was here to cause mischief and love his friends! ~ [Includes a couple of other Ticked Off mini-fics ("Clockwise" and "Summoners") because I don't wanna clutter up my profile by making new books] [Also posted on Ao3 under the same title and username!]

When the world ends, their only hope is to send one Quirkless man back in time. Back in his 14-year-old body, will Midoriya Izuku be able to save the world that shunned him all his life? And will he finally be able to become a hero this go around? Good thing he had time as a vigilante to practice.
