10 Worst Things The Joker Has Ever Done On-Screen

The DCAU’s Tim Drake wasn't quite as blessed as his comic book counterpart. While he wore the Tim Drake name, writers Bruce Timm and Paul Dini infused him with elements of Jason Todd's backstory and personality. Due to the series being aimed at the kiddies crowd, the level of violence and death they could display was limited. Brutally killing a Robin was not an option.

So, to make up for it, the Joker kidnaps this Todd/Drake hybrid and tortures the poor kid into total insanity. All is revealed in the Batman Beyond (will they ever make a live action film of this series?) movie, Return of the Joker. Joker and Harley kidnap the boy and break him mentally and physically until he leaks all of Batman's secrets. They then dress him up as an adolescent Joker and call him J.J. (Joker Junior).

Fast forward to the future and Tim has a microchip in his head that allows the Joker's consciousness to take over. By this time, Tim had moved on from the trauma and now enjoyed a normal job and a loving family. Just when he thought the games were over, the Joker torpedoes his life all over again.

Just pure evil.
