As leader, J-Man's costume bore the strongest resemblance to the original Joker, while other Jokerz dressed in some variation of clown costume.
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.
On the night of Warren McGinnis's murder, J-Man's gang arrived and started wreaking havoc. Terry started a fight with them, but as more came, and he was forced to flee on one of their motorcycles. The gang chased Terry down a seldom-used road where they were confronted by Bruce Wayne, the owner of the property. Together, Wayne and Terry manage to fight off the gang.
Some time later, J-Man's gang crowded around an illegal arms dealer who shows them some of his impressive merchandise. However, Batman showed up and broke up the sale. In an unfortunate accident, J-Man accidentally blew up the delivery van while shooting at Batman.
J-Man later went on a destructive rampage around Gotham City when one of his gang members, Scab, stole a nuclear-powered aircraft. Though Batman ultimately incapacitated the aircraft, J-Man and his men escaped. He was later present when Batman and Ten broke into the Jokerz' hideout while searching for her apparently-kidnapped family. He took part in the ensuing battle until the police broke it up.
J-Man was mainly a prankster with a big ego, and had little in the way of unusual abilities or skills. An unimpressive fighter, he mainly used his gang as his muscle.
