Manga creator Yuichi Hasegawa revealed in an April 24 blog entry that he will launch a new Raideen manga spinoff series titled God Bird in the July issue of Jive's Monthly Comic Rush magazine on May 26. "God Bird" was a transformation mode of the titular robot in Sunrise's 1975-1976 Brave Raideen anime series. The new manga will mark the 35th anniversary of this super robot anime, which was co-directed by Gundam creator Yoshiyuki Tomino.

Hasegawa had previously created the MAPS manga and anime franchise. Besides God Bird, his other manga projects based on classic robot anime series include Gundam vs. Ideon: Counterattack of Gigantis, Mobile Suit Crossbone Gundam, Mobile Suit Victory Gundam Side Story, and Chōjū Kishin Dancougar Burn. ADV Films released the 1994 video anime remake of MAPS in 2005
