Hylla used to hate Percy Jackson and his girlfriend Annabeth Chase for their roles in destroying her mentor, Circe's Island. She enjoyed imprisoning him after he came to the Amazons; However, she released him from prison after she needed to defeat Ortera. When the Amazons and the Twelfth Legion Fulminata teamed up to defeat Polybotes and his forces, Hylla had nothing but respect for Percy and backed him up when he insisted that Romans and Greeks don't have to be enemies because they're all on the same side.
