When his parents were gunned down in front of him, young Bruce Wayne resolved to rid Gotham City of the criminal element that took their lives. He trained extensively to achieve mental and physical perfection, in addition to mastering martial arts, detective techniques, and criminal psychology. When he returned, Bruce was inspired by a bat in his ancestral home of Wayne Manor. He then became Batman who fought crime with the aid of specialized gadgets and vehicles and operated out of a secret Batcave underneath Wayne Manor. Batman led a successful twelve-year, crime-fighting career until he was publicly unmasked by Scarecrow during the Arkham Knight Incident. Following the incident, with his identity fully exposed, Batman initiated The Knightfall Protocol and disappeared from the public eye. Despite that, his legacy lived on with the citizens of Gotham.
