Seth Voelker

Seth Voelker is the Marvel villain known as Sidewinder, a mercenary operative who became a founding member of the Serpent Society, a professional guild of snake-themed criminals. He possesses a teleportation cloak that allows him to instantly escape danger.

Seth Voelker slithered onto the Marvel scene in 1980, a Bronze Age creation from the powerhouse team of Mark Gruenwald, Ralph Macchio, George Pérez, and Gene Day — a debut pedigree that alone makes Marvel Two-in-One #64 worth hunting down. Over the decades he's built up affiliations with some of Marvel's most cold-blooded organizations — the Serpent Society, the Serpent Squad, and A.I.M. — keeping dangerous company alongside the likes of Sidewinder, Anaconda, and Captain America himself across the pages of the Captain America series where he's most at home. With three key-issue appearances to his name and a presence stretching from 1980 all the way to 2025, Voelker is a cult favorite for collectors who appreciate the deep, richly textured corners of the Marvel Universe. If you love Bronze Age villainy with real staying power, Seth Voelker rewards the dig.
