The Joker

"All it takes is one bad day to push the sanest man alive to lunacy." - Joker, The Killing Joke

The Joker is a character from the DC Universe. More particularly, he is an enemy of Batman. Despite his name, he is not to be taken lightly.

In the Batman film The Dark Knight, he is portrayed by Heath Ledger, which has resulted in many Mary Sues taking this sociopath in their arms, claiming he was just misunderstood and turning him into a woobie.

For more information about his many incarnations in comics and other media, see the Batman wiki.
