A former steel worker at the Roxxon Oil Company, Blanche Sitznski was noticed by the executives and chosen to become a special agent in covert operations. Having been well-adjusted to villainy as a teacher at Taskmaster's Academy, Blanche accepted the offer and was bioengineered to have various serpentine features, such as the ability to elongate her limbs, breathe underwater, and a skeletal structure laced with adamantium. For her first mission, Roxxon president Hugh Jones sent Anaconda, along with three other snake-themed villains employed by the company called the Serpent Squad, to retrieve the mystical Serpent Crown. Though Anaconda and her teammates Black Mamba and Death Adder were defeated by the Thing and Triton, the mission proved to be a success when the group found the Serpent Crown and Sidewinder returned it to Hugh Jones.

Anaconda possesses the ability to elongate her limbs, entwine them around persons or objects, and constrict. The entire skeletal structure of her arms and legs has been replaced by artificial adamantium alloy-based bones in the basic configuration of a snake's bodily skeleton. Her arms, normally 24 inches from armpit to wrist, and her leg, normally 35 inches from hipbone to ankle, are able to elongate to about one and a half times their normal length. When she extends her limbs in this fashion, the muscle tissue gorges with blood, swelling the limbs so that each looks like a massive, powerful snake. These four constricting limbs are capable of exerting enough pressure to radically deform a one inch-thick steel tube, two feet in diameter. Once Anaconda has fully entwined her serpentine limbs around a human-sized foe, there are few human beings able to get sufficient strength to break her grip. Anaconda has been surgically given artificial gills to enable her to extract oxygen from water in order to breath. She can now breathe while underwater indefinitely, as well as breathe on land. As a by-product of the extensive bio-engineering done to her body, Anaconda possesses superhuman recuperative abilities. Her body can heal from ant non-fatal wound many times faster than normal human beings.
