While the Baron uses his war mecha to fire at the clown, the Joker nimbly avoids his cannonfire. Eventually, the Baron gets smart and fires missiles. However, before the Baron can react, the Joker uses one of his television bombs to destroy the Baron's mecha. The Baron thinks he still has the upper hand, but the Joker reveals a small army of fellow Arkham inmates, including Clayface, Harley Quinn, Talia al Ghul, Solomon Grundy, and Poison Ivy. As the Baron tries to cut the Joker down, Joker shoots him dead.
One Crazy Family

Joker, finding another kindred homicidal spirit, proposes an alliance. Kefka agrees wholeheartedly.
Throughout the next few days, Kefka and Joker set about releasing inmates from the Asylum, occasionally enhancing them with the drug, Titan. One patient, however, doesn't need the formula to impress the Joker: Psycho Mantis. So to prove his worth, Kefka sends the Special Ops agent to destroy SHODAN, to resounding success. Joker also frees Sweet Tooth from his cell in Arkham.
After Sweet Tooth murders the would-be usurper, Officer Tenpenny, Joker congratulates him on his victory.
