Batman was a costumed crime-fighter and superhero operating in Gotham City. He was also the founder of the Batman Family and the mentor of Dick Grayson, Barbara Gordon, Jason Todd and Tim Drake. Some time before the events of Gotham Knights, Batman apparently died in an explosion. Leaving the team the Belfry and some of his old equipment, his trainees vowed to continue his mission.
