Fan Casting Bruce Wayne in Batman Beyond Animated Movie Series

The original Batman, although initially reluctant, later becomes Terry's employer, mentor, and predecessor who guides Terry through the Batcomputer but also occasionally ventures into the field to help his successor if the situation demands it, despite the risks associated with his age. During his final mission, rescuing a wealthy heiress as the Dark Knight twenty years before the events of the main story, Bruce suffered a heart attack that nearly cost him his life, forcing him to break his primary moral principle by threatening to kill a criminal with a gun in self-defense. Horrified that he nearly used the type of weapon that took his parents' (Thomas and Martha) lives and the very thing that drove him to become a vigilante, and afraid of what he might do next, Wayne reluctantly hung up the cowl.
