Knockout

Bursting onto the scene in 1996 courtesy of creators Beau Smith and Marcelo Campos, Knockout made her DC debut in the pages of Guy Gardner: Warrior and has kept remarkably powerful company ever since — sharing adventures with the likes of Superman, Lex Luthor, Green Lantern, and Firestorm. Her appearances across Villains United speak to a character who operates in the shadowy, morally complex corners of the DC Universe, and the fact that her catalog footprint stretches all the way to 2026 confirms she's left a genuine mark on the Modern Age. A character worth tracking down for fans who love digging into the deeper cuts of DC's rich roster.
