Breaker

This is Breaker from Killing Time. He breaks stuff. Accidently, on purpose, it doesn't matter. He just breaks stuff. Particularly other peoples bones. He's an ex-biker who's joined one of the ninja clans. He also becomes a good friend to James, the story's protagonist. He has more tattoos than I've drawn here but you get the idea.

He might not look like a ninja but he is. Stealth just aint his specialty.
