The Joker was the longtime nemesis of Batman and has been the most notorious supervillain.
His most notable act was for the murder of the staff of the Daily Planet, including reporter Lois Lane, the wife of Superman. It was this act that caused the anti-hero Magog to avenge Lois' death by murdering the Joker in cold blood. Magog's actions were largely supported by the general populace which led to him being acquitted of all charges relating to the murder of the Joker.
