Bonk

Bonk was a member of the Jokerz gang who assisted the resurrected Joker in his comeback campaign. Ben Knox, alias Bonk, was a large, muscular goon who often let his temper overpower his judgement. This resulted in his death when he openly questioned the Joker's plans, and the Joker shot Bonk with a dart containing his "Joker toxin" and killed him.

Comments

Note that Bonk only dies this way in the un-edited version of Return of the Joker. In the censored version, Bonk instead gets a dose of "laughing gas" and dies laughing.
