Izuku has SUPERHOT powers.

It started when he was young. He would freeze, and the world would slow. It moved as he moved, breathed as he breathed. Izuku did not know the curse of a quirk he would obtain. The curse called SUPERHOT.

As he aged it grew stronger and stronger, day by day, the world waiting for him, time itself making an exception just for him, a mere child. So young, so much time. it was pain sitting still, for it meant the world did as well. He could only move so much, escape so much. It would catch him.

And then it would break him.

So much waiting, so much stagnation. So much time to think and think, standing as still as a statue as his mind raced miles ahead. He had too much time on his hands. He had done too much thinking; the world would soon become plastic to him. How many hours of philosophizing without stimulation could you take? Pondering life, the meaning of it all, trapped inside his mind. He couldn't move forever, he had to rest. Motion could never be constant. To a certain extent, everything was slow, even when he was moving. So when he was still, it was an eternity.

Izuku was a prisoner. He didn't know what he wanted anymore. At least he could become a hero and maybe help others with his power. Maybe his doomed life could save another, better one. Maybe he could find the key to taming his power, to subjugating the curse inside him?

Heh, even after all his thinking, after all his sanity had been mangled and distorted, the one thing he managed to keep was his foolish hope.
