[6][7] Birdman (voiced by Keith Andes) is an ordinary human who has been endowed by the sun god Ra with the ability to shoot solar rays from his fists and project quasi-solid "solar shields" to defend himself against attacks (Birdman's origin is only vaguely, and only briefly, hinted at during the series.

After he had acquired his avian—and other—powers, he was recruited by a top-secret government agency, Inter-Nation Security, and now works full-time fighting crime, assisted by his pet eagle, who responds to the name of Avenger.

In addition to the abilities he received from Ra, Birdman also possesses the power of flight, thanks to the giant wings which sprout from his back.

She was seen in Mayor Huckleberry Hound's flashback as the referee of the infamous final fight of The Funky Phantom where she pulled him out of the ring after he misused his ghostly abilities on Mightor.

Another episode has Space Ghost villains Brak, Zorak and Moltar cosplaying as the Galaxy Trio to infiltrate a convention.

On July 17, 2007, Warner Home Video released Birdman and the Galaxy Trio: The Complete Series on DVD in Region 1.

[15] Birdman also accidentally appeared on the menu screen for the DC Super Heroes: The Filmation Adventures, a DVD set which featured DC Comics-based superhero cartoons produced by Filmation for The Superman/Aquaman Hour of Adventure (which coincidentally premiered the same day as Birdman and the Galaxy Trio), in 2008.
