Dee-Dee twins in Batman Beyond: Return of The Joker.
The Dee-Dee Twins love the thrill of being a part of the Jokerz Gang and think it's exciting to be working for the big man himself, The Joker. The Deeds are Olympic-level acrobats, able to fight with overwhelming coordinated attacks. Opponents underestimate their playful, raggedy Ann-like smiles only to wind up brutally injured. Also known as Delia Dennis and Deidre Dennis.
Twin sisters Delia Dennis and Deirdre Dennis were the granddaughters of Harley Quinn. Under the joint alias Dee Dee, they joined the Jokerz and followed in their grandmother's footsteps as "hench-wenches" of the original Joker.
