What is the Joker’s real name? How did he become so insane?
The Joker’s real name is unknown. Nobody knows his actual past and nobody has ever cared to find out because it doesn’t really matter. His earliest known confirmed activity began some time in 1965, as a prankster plaguing the Gotham Museum of Art, but in 1972 a robber was apprehended who went by the new identity of “the Joker”. As the years progressed, he became more and more mentally unhinged and villainous, committing countless crimes (all with “a criminal twist”) for which there finally came no settling account-including murdering many people who irked him or interfered with his mayhem. In the late 1970s he settled on being an agent of chaos who took delight in creating disasters like sinking ships.
