- Sidewinder (Seth Voelker), was an economics professor. He failed to make tenure and was hired by the Roxxon Oil Company as an economic analyst. He discovered their criminal schemes and they permitted him to apply for mutagenic alteration. Sidewinder was hired by Roxxon to retrieve the Serpent Crown.
- Anaconda (Blanche Sitznski), was bioengineered by Roxxon's Mutagenics Division to have various permanent serpentine features. Her skeleton was laced with an artificial adamantium, giving her the ability to elongate her arms and legs, which she uses to constrict her enemies. She has also been surgically provided gills so she can breathe underwater.
- Black Mamba (Tanya Sealy), was an ex-call girl, chosen by the Roxxon Oil Company to partake in a covert operation to retrieve the mystical Serpent Crown. Roxxon surgically implanted a special component in her brain which enables her slight telepathic abilities. She also projects a cloud of energy known as darkforce.
- Death Adder (Roland Burroughs), underwent surgery thanks to the Roxxon Oil company, giving him gills, claws, and a bionic tail, as well as certain other physiological changes. As a result of a mistake during the surgery to give him gills, Burroughs was rendered mute.
