Who the hell is Mad Dog?!

BIO:

This splendid biker specimen got his road name Mad Dog when he still was in his early teens when he got into an argument in his fathers Motorcycle Club(From now on MC) with one of the already patched members. No one remembers what argument was about but fight started, swinging and kicking then in middle of the fight boy bit other guy in the neck, soon after other members rushed in to get the boy off and get other dude to hospital real quick. Since then he himself became patched member of Devil's Own MC - Mad Dog. It was real cliche nickname but so very fitting.
Mad Dog loves fighting and it has gotten him in lot of trouble, even spent some time in youth detention center. As he grew up he had gotten quite proficient in fighting and was notorious for really reckless moves and one day after yet another bar fight GM Zeno Kichi saw the young man and offered a deal in OBW to which Mad Dog responded ''So I'm getting paid for beating up people and I don't get into trouble? Hell yeah!''

Notes:

Mad Dog does what he does for fun of it and his understanding of fun can get quite messy. Loves underhanded tricks.
