now be superfluous. While engaged in a geophysical survey, he encountered Yondu, one of the humanoid natives of the planet, who attacked him, but he stopped it. He kept this secret, as it was illegal for this species to attack a colonist. When the alien Badoon launched an attack on Centauri IV, annihilating the human colony and methodically eradicating the natives, Astro and Yondu attempted to escape in Astro's ship. They were overtaken and transported to Earth, where the Badoon Leader used a device to look through Astro's mind and see his origin. There they escaped in the year 3007 A.D. and joined with two other survivors of Badoon's massacre, the last Jovian Charlie-27 and the last Plutonian Martinex to form the Guardians of the Galaxy, with himself as the leader.

Quest for the Shield and release from containment suit After returning to his own time, Astro became involved with his teammate Aleta after she was freed from her physical merger with her ex-husband Starhawk. Astro went on a quest to find the lost shield of Captain America. He battled Taserface and the Stark during the quest,
