Anaconda

Anaconda, real named Blanche Stizinski, is a member of the Serpent Society and is the only female member of the group, though they are occasionally aided and led by Madame Viper.

Origin
Blanche "Blondie" Sitznski was a former steelworker working for Taskmaster and his Academy in Pittsburgh, Pennsylvania, until she was contacted by Roxxon and hired to retrieve a mystical object known as the Serpent Crown. In order to achieve her mission, she was bioengineered by Roxxon's Mutagenics Division. They modified her skeletal structure, lacing her skeleton with Adamantium, which enabled her to elongate her arms and legs. They also surgically implanted gills and scales in order for her to breathe underwater. She was then trained alongside three other snake-themed mercenaries -- Sidewinder, Black Mamba, and Death Adder -- and set out to accomplish their task.

Powers and Abilities
Anaconda has the superhuman ability to elongate her limbs and constrict her opponents. Her arms and legs are able to elongate to about one and a half times their normal length (though most artists show her greatly exceeding that length), while her muscles engorge with blood, giving the appearance of massive, snake-like limbs. Once she has entwined her limbs around a human-sized foe, there are very few human beings able to break free of her grip. She has also been surgically given gills, which allow her to breathe under water, and modified lungs for extracting oxygen from water. Due to all the bio-engineering performed on her, Anaconda has incredible recuperative abilities and she is able to heal non-fatal wounds several times faster than a normal human being.

She has superhuman strength, able to lift c. 2 tons. She is also an excellent swimmer.
