Debuting in 1969’s Marvel Super-Heroes #18, Vance Astro, a.k.a. Major Victory, was the leader of the original Guardians of the Galaxy. Originally named Vance Astrovik, he joined the U.S. Air Force upon becoming an adult and was recruited for the United States’ first long-term interstellar mission. Vance was put into suspended animation and a special skin-preserver to prevent him from aging, and he eventually arrived at his destination, Centauri IV, 10 centuries later. However, by that point humanity had already lived on Centauri IV for centuries thanks to faster-than-light travel technology, and they’d been unable to intercept Vance’s ship beforehand. Now living a millennium in the future with new telekinetic powers, Vance decided to keep carrying out his original mission, and that led him to eventually meeting the other original Guardians and forming the team. It’s since been established that Vance hails from Marvel’s Earth-691 timeline, not the main continuity.
