She made her debut in Gabe Goes to School when Lillie brought her new friends over to her house, she came running out with Lillie's Lillipup and Lillie's mother and older brother. Team Rocket arrived and attempted to steal Vulpix and Lillipup, but accidentally captured Lillie and decided to take her instead which angered Lillie's mother who fought to save her daughter. Lillie was reunited with her Vulpix and Lillipup, and Gabe had Pik blast of Team Rocket. Vulpix and Lillipup were then asked by Lillie to join her traveling journey and they agreed.
Vulpix is very caring and loyal toward her trainer.
