The Joker

"You and me? I used to think we were going to do this forever, but you're no fun anymore, Bats. I'm not laughing anymore! No more grins, no more smiles, let's say I tell one last joke!"

-The Joker

The Joker is a supercriminal who operates in Gotham City using a variety of deadly methods in his crimes, often being based around party gags. He is considered to be the archnemesis of Batman and has caused him the most pain of all his foes. The Joker wears the visage of a clown but is one of the most feared men in Gotham City.

The Joker's true name and origin are unknown, even to Batman. Joker proves to have an endless supply of stories for his possible pasts, with each one containing only one thing in common: Batman. Joker blames Batman for his creation.

His favorite story to tell is that he was once a failed comedian with a pregnant wife, desperate for money, he started working with the gangs of crime boss, Carmine Falcone. After the gang murdered his wife, heartbroken, he took part in a robbery where his only instructions were to take the identity of the Red Hood. At the night of the robbery, the heist is stopped by Batman who takes out the gang members and leaves the Red Hood for last, scared, he backs up and ends up falling from a platform into a vat of acid, turning his skin white and his hair green. It is unknown if this tale is true.

The Joker is perhaps Batman's most personal foe, as he is the one that murdered the second Robin, Jason Todd. As well as being the one to cripple Barbara Gordon, the former Batgirl, paralyzing her for life in a wheelchair. The Joker has made a large impact on the lives of Batman and his allies.
