Pallas
Pallas (パラス Parasu) is a Goddess with a profound link to Athena that goes back to the ages of myth. She harbors a deep and mysterious love-hate bond towards Athena, and her influence causes Athena's power to wane. Leading an army comprised of Palladian warriors known as Pallasites, she aims to destroy Athena's body and soul, as well as the Saints who would get in her way. Her Pallasites wear armors called Chronotectors which are similar to the cloths of the Saints of Athena. Pallas is believed to be the primary antagonist of the second season of Saint Seiya Omega. Spoiler Athena tells Seiya to kill Pallas with his golden blade in order to cut the bond that ties her and Athena together thus preventing another holy war. However, Seiya is unable to bring himself into committing murder, much to the surprise of Pallas. (Source: Seiyapedia)
