What makes a great Joker?
Is it that smile? The laugh? The demented things he does?
Ever since the Joker first appeared in comics 76 years ago, he has been tormenting Batman and fascinating fans. He's seen as the best villain in the comic book world due to his unpredictability and the fact that he is the polar opposite of Batman, among other things.
As the story goes, the Joker was partially based on the 1928 silent movie The Man Who Laughs, starring Conrad Veidt. It's been the subject of much discussion for decades as to whether Jerry Robinson or Batman co-creators Bob Kane or Bill Finger first came up with the character, or if it was a combination of all three.
Nevertheless, the Joker has been captivating mass audiences for a half century since first appearing on the 1966 "Batman" TV series. Below, we rank the major Jokers seen onscreen.
