Goku?

A god-like being from who knows where that is OBSESSED with fighting strong people.

He doesn't kill, at least not intentionally, even to his own detriment, he would only (intentionally) kill anyone who threatens the planet and his opponent if they ask for a fight to the death.

He's pretty hard to anger, but you won't like what happens when he gets mad during a battle.

He has an omnipotent form, in said form he has one big white eye, his muscles are larger, he grows to the size of a skyscraper, grows wings for extra air mobility, and his entire body is black with white outlines.

He looks similar to a saiyan named "Goku", but he isn't a saiyan. And he for sure isn't human..

Wears a grey and black gi.

The pupils in his eyes are pitch black.

His punches/kicks hit as hard as an attack from an Ozaru

He has multiple abilities that are similar to Goku's. But he has plenty abilities of his own.
