-Easily Batman's greatest foe, Joker has caused more then enough problems for Nightwing and Oracle as well. He killed the second Robin, Jason Todd, something Batman had a hard time getting over, and probably still hasn't. The event was hard on Dick as well, he felt he wasn't there enough for Jason, and it is this Robin that is always in his nightmares. It was thanks to the Joker that Barbara is living the life she if, shooting her in the stomach as she answered the door, and paralyzing her from the waist down. And the bitter irony was that he didn't even know he had taken out Batgirl, it was just part of his plan to drive her father Jim Gordon insane. Most recently, Dick was just shy of killing the Joker, an act he is still trying to get over.
