Burchell Clemens

Burchell Clemens is a Marvel villain who had his jaw surgically replaced with a powerful bionic prosthetic, granting him steel teeth and the ability to dislocate and stretch his mouth wide enough to crush cinder blocks or engulf a human head. Operating as Cottonmouth, he became a feared enforcer within snake-themed criminal organizations.

Burchell Clemens slithered onto the Marvel scene in 1985's Captain America #310 — a Bronze Age debut courtesy of Mark Gruenwald and Paul Neary — and has been coiling through the Marvel Universe ever since. A card-carrying member of both the Serpent Society and A.I.M., Clemens runs with a genuinely dangerous crowd, sharing panels with the likes of Anaconda, Cottonmouth, and Rattler across titles including Captain America, Thunderbolts, and Black Panther. With two key collector issues to his name and a publishing history stretching an impressive four decades to 2025, he's proven far more than a one-and-done villain. If you're chasing the deeper cuts of Marvel's villainous ecosystem, Burchell Clemens is exactly the kind of figure worth tracking down.
