Dementor
Dementor is a villain who emerged as an antagonist in the pages of Guy Gardner: Warrior, opposing the hard-hitting former Green Lantern Guy Gardner and his allies in DC's gritty mid-1990s action milieu.
Emerging from DC's hard-edged mid-nineties action scene, Dementor made their debut in Guy Gardner: Warrior #22 in 1994, conjured by the creative team of Beau Smith and Mitch Byrd. With a name that radiates menace, this villain carved out a niche in one of DC's most combative corners, sharing pages with the likes of Guy Gardner himself, Green Lantern, Arisia, and Tiger-Man across the Guy Gardner: Warrior series and its annuals. Compact in appearances but concentrated in impact, Dementor is exactly the kind of Copper/Modern Age antagonist that rewards the dedicated collector willing to dig into the grittier, street-level side of the DC Universe.
