Word of the appearance of an unexpected Bat-villain has arisen — particularly, a character last seen in Batman, Inc.#5. September 4, 2013 will bring Batman #23.1: The Joker to shelves, and thus, an appearance by the character Jackanapes is imminent.
While at a zoo, the Joker will have a flashback to a childhood memory that will trigger his need to take Jackanapes under his wing. It is here that Joker will take on a new, twisted role: that of a mentor. But why is he training Jackanapes to be a villain? What use will he have for him?
Only time will tell what gags he might have up his sleeve… Perhaps the Joker knows.
Additionally, Jackanapes will appear in the upcoming Damian: Son of Batman miniseries.
