Only one volume was ever collected.[4] From 2002 to 2012, Masami Yuki moved to Weekly Young Sunday, a seinen magazine, and produced Birdy the Mighty Evolution, a new version of the story.[5]

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.[14] 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.".[15] 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."[16] Josh Viel of the Escapist, praised the visuals and soundtrack of the first season, bringing particular mention to the show's use of foreshadowing.[17] 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.".[18] Further points were directed toward the second season for having the same issues, yet still recommended the series as a whole.[19]


Zack Snyder said the anime was an inspiration for his take on Man of Steel.[20]
