In Batman, solitary billionaire Bruce Wayne (Michael Keaton – Birdman) was inspired to become the famous vigilante crime-fighter after the unavenged death of his parents. After terrorising the criminal underworld, he ended up dropping their killer, Jack Napier (Jack Nicholson – A Few Good Men) into a vat of chemicals. The Joker was born along with a new type of villain. The super villain. Eventually he was defeated (AKA killed), and a relative peace returned to Gotham City.
