Quincy McIver

Quincy McIver is a Marvel villain known as Cottonmouth, a street-level criminal who became a deadly enforcer with a cybernetically enhanced jaw capable of crushing steel. He has operated within ruthless organizations including the Serpent Society and A.I.M.

Quincy McIver arrived in the Bronze Age Marvel Universe courtesy of the legendary creative duo of Chris Claremont and John Byrne, debuting in Power Man #49 in 1978 — and he's been a persistent, dangerous presence ever since. Affiliated with both the Serpent Society and A.I.M., he moves in some of Marvel's most formidable villainous circles, sharing the page with heavy hitters like Captain America, Anaconda, and Bushmaster across titles including Captain America, Punisher War Journal, and Battle Scars. With four key-issue appearances to his name and a publishing history stretching nearly five decades to 2025, McIver is far more than a footnote — he's a durable piece of Marvel's Bronze Age legacy that serious collectors keep finding reasons to revisit.
