This Batman and Nightwing original production cel from The New Batman Adventures Animal Act episode is a rare opportunity to get these characters together!
The New Batman Adventures (often shortened as TNBA) is an American animated television series based on the DC Comics superhero Batman, and is a continuation of the 1990s Batman: The Animated Series. It was produced by Warner Bros. Animation and aired on Kids' WB from September 13, 1997 to January 16, 1999. The show lasted for 24 episodes, and was succeeded by Batman Beyond. According to the reference book Batman Animated, series writer Paul Dini originally wanted the new show to be titled Batman: Gotham Knights, but this idea was rejected by the other producers. To better adhere with the prior DVD sets of the original series, the DVD release of this series was titled Batman: The Animated Series Volume 4 (From The New Batman Adventures) and was given the opening theme from the prior series.
Stories in this series tend to give more focus to Batman's supporting cast, which include fellow crimefighters Robin, Nightwing and Batgirl, among others. The show also features guest stars such as Supergirl, Etrigan the Demon and The Creeper; characters who would later appear with Batman in Justice League and Justice League Unlimited. In addition, the series takes place around the same time as Superman: The Animated Series. The 2001 video game Batman: Vengeance and its follow-up Batman: Rise of Sin Tzu are based on this series.
