Gwen Stacy lived a life similar to her Earth-65 counterpart, though appeared to have gained her spider-powers at a younger age, and had been transported to an alternate reality while fighting Doctor Octopus. Realizing where she was, Gwen was forced to go undercover, attending Brooklyn Visions Academy as her spider-sense drew her there. There, she encountered Miles Morales, whom she clumsily introduced herself to as "Gwanda." However, Miles's own budding spider-powers caused problems when he accidentally stuck himself to her hair when trying to hit on her, forcing her to cut it off and eventually shave it into an undercut.
Gwen, following the similar lead of her counterpart from this Earth, Peter Parker, infiltrated the Alchemax facility, pretending to be a scientist. There, she encountered Miles again and subsequently saved him and Peter B. Parker whilst driving away Olivia Octavius. She clarified her identity to Miles, explaining her origins. She subsequently teamed up with Parker, Morales and several other alternate spider-people to find a way home.
