J-Man was the leader of the notorious Jokerz gang in the future Gotham City.
J-Man's costume bears the strongest resemblance to the original Joker, the only difference is that he wears a mask instead of make-up or a chemical that altered his appearance.
Like his namesake, J-Man took a sadistic pleasure in playing "jokes" on random bystanders, and was occasionally known to play for higher stakes. However, although he seemed to fancy otherwise, he was a far cry from the real thing, something Bruce Wayne himself sarcastically noted in their first meeting.
J-Man was mainly a prankster with a big ego, as such he had little in the way of actual threats. He mainly used his gang as his muscle, having little skills as a physical fighter.
