Alien Genius Deku

Izuku is considered a smart prodigy, but even with such a title, it means nothing to others without a quirk.

The moment he was labeled Quirkless by the quirk doctor, his life had changed for the worst. He was bullied by his peers and by his own sister even by someone he considered a friend, and neglected by his parents.

And when he found out he was adopted, he ran away and was adopted my Midnight.

Since then his life was normal. That is until out of nowhere a strange watch fell from the sky, that watch being the Ultimatrix.

With it he'll use it to be the hero the world needs.
