In Batman Beyond: Return of the Joker, it’s the year 2040 and Bruce Wayne has retired from crime-fighting, passing on the mantle of Batman to high schooler Terry McGinnis. This is when Joker (voiced by Mark Hamill) resurfaces in Neo-Gotham City, taking over the Jokerz gang and going on a crime spree.

The Dee Dee Twins, Delia and Deidre Dennis, are the granddaughters of Harley Quinn, who follow in her footsteps as the hench-wenches of the Joker. As members of the Jokerz gang, they face off against their nemesis Batman.
