Joker Tattoo
Appearing to be the most evil, deranged, and flat out psychotic killer of all comic book villains, The Joker is the primary antagonist of Batman. He is the complete opposite of Batman, in everything from appearance (Batman tends to be a rather large and muscular man, while The Joker is typically a man of average height or even taller possessing a skinny frame), to ideals.
