Chucko

Chucko was a member of the Jokerz gang who assisted the resurrected Joker in his comeback campaign. Apparently the leader of the bunch, Chucko (real name Charles Buntz) was a bald, overweight man who wore pink tights and a clown mask which he never took off. He is thought to have been killed falling from a Jolly Jack smokestack after Batman crashed the Batwing into it, as a result of Chucko shooting him down with a rocket launcher.

Alternate Timelines

In an alternate future timeline created by Chronos's time-tampering, Chucko served as one of Chronos's minions. Using future technology, Chronos gave him a wheeled, mechanical lower body and a double-sided energy sword (looking just a bit like Darth Maul's Lightsaber). However, after he sold information to Batman (Terry McGinnis), Chronos disposed of him by sending him back in time to die along with the dinosaurs. This timeline ceased to exist after Batman trapped Chronos in a time-loop.
