Plot
Birdy Cephon Altera is a Federation agent chasing interplanetary criminals to the planet Earth. While in pursuit of one such criminal, she accidentally kills a high school boy named Tsutomu Senkawa. However, there is a way to keep him alive. He ends up being merged into Birdy's body and must remain so until the repair of his body is complete.

So, Tsutomu is stuck sharing a body with an attractive, strong, and impulsive space police agent while trying to keep his family and friends from finding out about Birdy. In the meantime, Birdy continues her investigation. Together, they take on a secretive group of evil aliens planning to perform experiments on the unsuspecting inhabitants of Earth.

Manga
Written and illustrated by Masami Yuki, Birdy the Mighty was serialized in Shogakukan's shōnen manga magazine Shōnen Sunday Zōkan from 1985 to 1988, being serialized while Yuki was working on Kyūkyoku Chōjin R in Weekly Shōnen Sunday. Yuki eventually abandoned the project, leaving it unfinished. Shogakukan released a single volume, which was listed as "volume 1", on July 18, 1996.

Over a decade later after its original run, Yuki decided to make a reboot of the manga, keeping certain details from the original work. The series ran in Shogakukan's seinen manga magazine Weekly Young Sunday from December 26, 2002, until the magazine ceased its publication on July 31, 2008. It later ran in Weekly Big Comic Spirits from September 6–22, 2008. Shogakukan collected its chapters in twenty tankōbon volumes, released from June 5, 2003, to October 3, 2008.

Reception
Since its release in the West, Birdy the Mighty: Decode has received generally favorable reviews. Bryan Morton, from The Fandom Post, was positive toward the first season, citing the visuals and action as factors for it. In his review of the second season, while Morton stated that it was as enjoyable as the first, he was more critical of it. Several criticisms were drawn to Tsutomu and his friends being more sidelined in the story, and the animation, which he pointed out as, "...appearing to have been animated on a shoestring budget.". Bob Muir, from Japanator, noted the ending for the show made it feel rushed, but overall recommended the series, calling it "...just plain fun, with no insipid moe characters or deathly serious world domination plots to drag it down." Josh Viel of the Escapist, praised the visuals and soundtrack of the first season, bringing particular mention to the show's use of foreshadowing. On DVDTalk, Todd Douglass Jr. commended both seasons for their character development, though criticized the pacing of the first season, as well as the antagonists, calling one of them, "... more of a Cigarette Smoking Man kind of guy and really seems to just be some shadowy figure doing what he wants to do in the sidelines.". Further points were directed toward the second season for having the same issues, yet still recommended the series as a whole.

Legacy
Zack Snyder said the Birdy the Mighty anime series was an inspiration for his take on Man of Steel.
