Cornell Stokes AKA Cottonmouth has bionic enhancements on his jaw and teeth, which allow him to open his mouth big enough to engulf his enemies and he became a prominent enemy of Luke Cage. Cottonmouth is a member of the Serpent Society, a team of snake-themed villains who fight against Captain America.
Marvel Cinematic Universe
In the MCU, Cottonmouth is not a snake-themed criminal but rather a prominent gangster operating out of Harlem, New York. Cornell was the son of Harlem's then crime-lord "Mama Mabel" who forced him into the business while all he wanted to do was become a pianist. He got the unwanted name "Cottonmouth" when during a fight he had some of his teeth punched out, forcing him to temporarily keep cotton balls in his mouth.
Years later Cottonmouth became the most prominent gangster in Harlem from his connections to Diamondback and became an enemy of Luke Cage only to die at the hands of his sister Mariah Dillard who hated him for having been Mama Mabel's favourite.
