Gwendolyne Stacy comes from a universe where she was bitten by a radioactive spider instead of Peter Parker. Like Spider-Man, Gwen initially used her powers for financial gain by becoming a professional drummer while maintaining a secret identity as “Spider-Woman” and drumming off to the side in her friends’ band, “The Mary Janes.” The Peter Parker of this Earth was bullied quite often, and Gwen often came to his defense, causing Peter to develop an inferiority complex. After Gwen revealed to him that she was Spider-Woman, Peter desired to be special like Gwen and created a serum which turned him into that universe's version of the Lizard. The serum causes Peter to go mad, and Gwen is forced to fight her friend. Due to the serum, Peter dies in the middle of the battle, and Spider-Woman is falsely accused of his murder and is on the run from the authorities. Soon after, Gwen is pulled into the fight against the Inheritors, which spans across the entire Spider-Verse.
