The Metal Hero: Metallix

Izuku Midoriya at the age of 4 had his world shattered because of the fact he didn't have a quirk. Since then he was bullied by his peers, the worst being his former childhood friend, Katsuki Bakugo, who took it upon himself to torment him. Years passed, the bullying never stopped. One day Izuku found himself the roof of his school where he was cornered by Bakugo and his goons, preparing for another beating, he sat helplessly waiting for the onslaught. It was at this moment a voice called out and in a blinding light transformed into a robot that bared an uncanny resemblance to a certain blue hedgehog.
