Jack Flag
Jack Flag (real name Jack Harrison) is a fictional character appearing in American comic books published by Marvel Comics. He is typically depicted as a superhero and a member of various cosmic-themed teams.
Initially appearing as a street-level vigilante inspired by Captain America, Jack Flag gained cosmic powers after being exposed to the Living Tribunal. These powers typically grant him enhanced strength, speed, durability, and the ability to manipulate gravity.
His first appearance was in Captain America #434 (December 1994). He was created by Mark Gruenwald and Dave Hoover.
Jack Flag has been affiliated with several teams, including the Guardians of the Galaxy, the United Front, and briefly with the Revengers during Norman Osborn's "Dark Reign." His character arc often involves grappling with his newfound powers and finding his place within the larger Marvel Universe, balancing his initial ideals with the responsibilities that come with cosmic abilities. He has been both a dedicated hero and, at times, a reluctant participant in larger conflicts.
