Izuku was so excited when he manifested his Quirk. Being able to combine with objects to make himself stronger? So cool! However, what he didn't expect, what no one expected, was what happened if he used his Quirk on people... (Or, What if Izuku's Quirk was the Fusion Ability from Dragonball Z/Steven Universe?)

Izuku was never Quirkless. Sometimes, Quirks hide until they are triggered. Izuku died and came back. He gazed into the abyss and it followed him home. Everything he thought he knew about the world is about to change because there are monsters lurking in the dark below. Izuku wonders if he is one of them. Crossposted to Ao3.

Apotheosis, the highest point in the development of something or if you prefer, the elevation of someone to divine status.

Villain Izuku, eventually OP as hell. Infinity Gauntlet AU.

"You seem to think that I was on your side at one point. I wasn't." Izuku had long since abandoned the hero's path, leaving those left behind in his wake wondering just what he plans to do and why he's doing it.

This is how Izuku Midoriya became the world's most dangerous villain. All it took was one bad day to make him descend into the pit of madness. He learned that life's a cruel joke and now, he'll show it to the world. There will be character death, violence, murder, mind breaking and above all laughter. And if you must go, go with a smile.

Izuku always wanted to be special. To have a Quirk. And one day he got his wish. Izuku found out he could "take" Quirks. Something Izuku didn't want. Unfortunately this Quirk came with a price. He needed more, to have more. So... he became a hunter. A predator. It's nothing personal, it's only natural selection. Better summary inside! Slight crossover with Heroes!
