Christy Fimple (portrayed by Kirsten Dunst) is teenage girl who gets dragged into the Gorgonites vs. Commando fight after they invaded her house, and who sides with the Gorgonites. She lives next door to Alan Abernathy who has a crush on her.
She is first seen when she walks into Alan's family toy store, looking for a toy for birthday present for her brother Timmy. She is he's next door neighbour who he has a crush on, and seems to be popular unlike Alan.
When the Commandos learn on Alan's interest in Christy and decide to take her hostage, immobilizing the Fimple household to force Alan into surrendering the Gorgonites. Alan and Archer sneak into the Fimple house to save Christy, but runs into her Gwendy dolls, whom Chip has engineered as auxiliary troops. Archer cuts Christy loose from her bonds and together they destroy the Gwendys before escaping.
