Croc Master

Few villains in the G.I. Joe universe carry quite the reptilian menace of Croc Master, who slithered onto the scene in 1987's The G.I. Joe Order of Battle #3 and has endured across an impressive 35-year publishing history stretching into 2022. A creature of the Copper and Modern Ages, he haunts the pages of G.I. Joe: A Real American Hero and beyond, keeping dangerous company with the likes of Cobra Commander, Firefly, and Raptor — a rogues' gallery that signals exactly where his loyalties lie. Whether you know him from the classic Marvel run or the IDW era, Croc Master is one of those gloriously specific, utterly committed villain concepts that makes G.I. Joe's world so endlessly rich and rewatchable.
