History
As a teenager, Gwen Stacy went to a demonstration on radioactivity and was bitten by a mutated spider. The bite transformed her, granting her amazing powers: a precognitive awareness of danger, adhesive fingertips and toes, and the proportional speed and strength of a spider. To the residents of New York, she is the dangerous vigilante called Spider-Woman, but you know her as Spider-Gwen!
At some point, Gwen bonded to an artificial symbiote, becoming Venom.[1]
