J-Man

J-Man is an antagonist in ''Batman: New War. ''He is the former leader of the future Maniax.

Personality
J-Man is an extremely malevolent and psychopathic individual, but is far from the real thing he's trying to copy. He is a ruthless sadist who takes pleasure in street violence and the petty crimes he commits for money, using the infamous Joker to gain money and power, and further his goals from robberies, extortions, assaults and even murders. J-Man also finds humor in the suffering and fear of his enemies, and also has a perchant for flamboyancy, lavishness and extravagance.
