Two-Face

Harvey Dent, also known as Two-Face, is the former district attorney of Gotham City who harbored schizophrenia because of an abusive father who beat him by flipping a coin. Harvey was Gotham's most heroic district attorney, dedicating his life to cleaning up the streets of Gotham, working with Jim Gordon and Batman.

However, one fateful night, Harvey was kidnapped by The Joker and held hostage by Harley Quinn in the warehouse on 250, 52nd street. When Joker was asked about Dent's whereabouts by Batman, Joker said that he was at a warehouse and Batman gave way.

Not knowing that the warehouse was rigged with bombs, Harley escaped and left Dent inside. Batman failed to save Harvey when the warehouse exploded. Half of Harvey's face was burned, and so was his father's coin which he had kept in his pocket. Harvey then went insane, and became Two-Face, a crime boss who used his burned coin to decide whether his victims lived or died.
