Birdman and the Galaxy Trio, or simply Birdman or The Galaxy Trio, is an American animated television series by Hanna-Barbera Productions that debuted on NBC on September 9, 1967, and ran on Saturday mornings until September 6, 1969. The program consists of two segments: Birdman, depicting the adventures of a winged superhero (created by Alex Toth, creator of Space Ghost) powered by the sun, and The Galaxy Trio, centered around the adventures of a patrol of interstellar superheroes. Each segment was a complete independent story, and the characters of each segment did not interact with those of the other, except for a bumper that has all four heroes defeating a prehistoric monster.
