What are the 10 worst things The Joker has ever done to Batman?
Wow, that's a lot. Has The Joker ever kidnapped any of Batman's love interests?
Yes, The Joker has definitely targeted Batman's love interests before. He kidnapped Selina Kyle (Catwoman) and held her hostage, and he also manipulated Harley Quinn into thinking that Batman had killed the Joker, causing Harley to try to kill Batman in revenge.
