Sentinel

Born in the fertile creative explosion of 1987's Copper Age, Sentinel made their debut in Megaton Explosion: Who's Who in Megaton Comics? #1 before finding a lasting home in the Image Universe — particularly across the pages of Youngblood, Team Youngblood, and Supreme, the high-octane titles that defined Image's bold early identity. With 76 catalogued appearances spanning nearly four decades and five collector-recognized key issues, this is a character with genuine staying power in a corner of comics that rewards dedicated fans. Sentinel shares the page with a vivid roster that includes Cougar, Riptide, and Jeff Terrell, placing them squarely in the thick of Image's action-packed ensemble storytelling. If you're diving into the wild, ambitious world of early Image and want a character with real roots and a surprising amount of depth to uncover, Sentinel is absolutely worth your time.
