Sentinel (Alan Scott)

Alan Scott, the original Green Lantern, rechanneled his mystical Starheart-derived powers under the Sentinel identity. A founding member of the Justice Society of America, he wields green energy for flight, constructs, and force fields — with a unique vulnerability to wood rather than yellow.

Stepping onto the DC stage in 1995 courtesy of creators Charles Moore and Stuart Immonen, Sentinel made their debut in the landmark anthology Showcase '95 #1 — a Modern Age arrival who quickly found their footing in the wider DC Universe. With appearances spread across Guy Gardner: Warrior, JLA, and Starman, this is a character who genuinely rubbed shoulders with the heavy hitters, sharing pages with the likes of Green Lantern, Batman, The Flash, Alan Scott, and Clark Kent himself. A 24-year publishing presence stretching all the way to 2019 speaks to a quiet but real staying power, and with a key collector's issue among their appearances, Sentinel is the kind of discovery that rewards the dedicated back-issue hunter willing to dig a little deeper into DC's rich modern era.
