The Final Joke

Harley's crew, Frank, and Kite Man hold an impromptu funeral for Ivy before they join forces with Batman to avenge her. While they distract Joker, Batman skydives to the top of the tower to take him down. However, Clayface inadvertently ruins the plan and gets the crew and Batman captured while Harley is forced into hiding. His takeover largely complete, Joker spends the next week subjugating Gotham and brutally torturing Batman and the crew, only to get bored. Hoping to help, Scarecrow unmasks Batman, but Joker uses an acid-shooting squirt flower on him for ruining the "mystery". Meanwhile, Harley revisits Ivy's grave, where Frank and Kite Man tell her the crew's going to be publicly executed, so she surrenders herself in exchange for their lives. Once her crew's safe, Harley tries to kill Joker, but he gets the upper hand. Instead of killing her, Joker decides to drop her in acid that will render her "normal." At the last minute, a resurrected Ivy saves Harley and drops Joker in the acid, though not before he destroys his tower and Gotham. Batman saves Harley and Ivy before disappearing in the debris. Reunited, the crew reflect on everything that has happened amidst Gotham's ruins. While they reflect, Batman is dead and The Joker emerges from the rubble.
