The arch nemesis of The Batman, Joker is a maniacal harlequin whose bizarre appearance and unerring instinct for the absurd have earned him a reputation as "the most dangerous criminal in the annals of crime." For Joker, each transgression he commits is an elaborate joke in which he tries to leave his victims dying with laughter - literally. More than any other enemy, Joker became inextricably linked to The Batman, as the crazed clown's plots began to take increasingly more personal tolls on the crime fighter.
