Did Scylla have any enemies

Yes, Scylla had enemies, most notably the sea god Glaucus. In Greek mythology, Glaucus fell in love with Scylla, but she rejected him. In his desperation, he sought the help of the sorceress Circe, who, spurned by Glaucus, poisoned Scylla out of jealousy, transforming her into a monstrous creature that terrorized sailors. This act solidified Scylla's enmity with Circe, as well as her tragic fate as a fearsome adversary in the sea.
