Batman Beyond is an American superhero animated television series based on the DC Comics superhero Batman. Created and developed by Paul Dini, Bruce Timm, and Alan Burnett and produced by Warner Bros. Animation,[1] the series began airing on January 10, 1999 on Kids' WB, and ended on December 18, 2001. In the United Kingdom, it began airing on September 4, 2000.[2] After 52 episodes spanning three seasons and one direct-to-video feature film, the series was brought to an end in favor of the Justice League animated series.[3] Depicting a teenaged Batman (Terry McGinnis) in a futuristic Gotham City under the tutelage of an elderly Bruce Wayne, Batman Beyond is the third series (chronologically the final series) of the DC Animated Universe, and serves as the sequel to both Batman: The Animated Series and The New Batman Adventures.[4] Though the initial announcement of the series drew mixed reactions, Batman Beyond was well-received and gained a cult following. Despite being conceived as a kid-friendly Batman series by Warner Brothers Animation, it ended up being darker than its predecessor Batman: The Animated Series.[5][6]
