A.J.

The youngest, 19 year old, fighter in Ma's Pit Brawl Family. He wears a mask that looks like a fish head and never takes it off. In addition, the only time anyone has heard him speak was when he told Ma that his name was A.J. Though he is willingly mute, A.J.'s actions give him the reputation as a reliable and trust worthy guy. A.J. isn't the one you try to steal from because he doesn't have much. He's the guy who go to for muscle. The strong silent type who you call to get things done. Not a John Wick, more reliable henchman that doesn't need to be micromanaged.
He uses twin blades when fighting and has built his battle strategy on finishing his opponents quickly. He takes an herbal based steroid, no one knows how he gets it, but after drinking the purple mix he goes into a hyper adrenaline state. He fights as a Barbarian.
