A further Gwen clone appears in the "Sibling Rivalry" crossover storyline between "Superior Spider-Man Team-Up" and "Scarlet Spider". She joins the Jackal (alongside Carrion and a regular Miles Warren clone) in capturing Superior Spider-Man and Kaine. She is sympathetic towards "Peter" and Kaine, but at the same time utterly loyal to the Jackal. When the Spiders break free, Superior Spider-Man disarms and attempts to kill her, but is stopped by Kaine. When the Jackal's lab is engulfed in flames, Kaine offers to save her, but she refuses, and is seemingly consumed by the fire.
