Birdy the Mighty (鉄腕バーディー, Tetsuwan Bādī?) is manga by Masami Yuki, who is best known for producing the long-running series Patlabor. His initial work on the series was quickly abandoned, but it was made into an anime, which was produced and, on the last episode, scripted by Yoshiaki Kawajiri, who is known for anime titles such as Vampire Hunter D, and Ninja Scroll. The character designer and animation director for the series was Kumiko Takahashi. In 2003, Masami Yuki began serializing a second, more ambitious Birdy the Mighty manga serialized in Weekly Young Sunday, which will again be made into an anime.

A new TV anime adaptation, titled Tetsuwan Birdy: Decode (鉄腕バーディー DECODE, Tetsuwan Bādī DECODE?), which is being animated by A-1 Pictures and produced by Aniplex, premiered in Japan on TV Saitama and other broadcast networks from July 4, 2008. The series is directed by Kazuki Akane (director of Vision of Escaflowne), written by Hiroshi Ōnogi, with its character designer and overseeing animation director being Ryo Timo. It is also slated to air on the satellite network Animax from July 14, 2008 with another season slated to air on January 2009. The TV series is featuring a different seiyū cast from the original OVA series.
