ashura-ou

Ashura-ou is initially introduced as the god of war and guardian of Heaven under the former Emperor. He died defending his lord against Taishaku-ten and was revered as a hero. However, it is revealed at the end of the manga that he had actually orchestrated Taishaku-ten's rebellion. Through Kuy-ou’s prophecy and his own visions, Ashura-ou knew of his future son's true nature as the "true Ashura." Despite this, he wished for his son to be born. To change destiny and prevent Ashura's awakening, he sought Taishaku-ten's help, who agreed in exchange for Ashura-ou's body. Ashura-ou married Shashi, one of the priestesses bearing one of Ashura's seals on her forehead, so she would be his son's mother, whom Ashura presumably would not want to kill. He had Taishaku-ten seize the throne and rule cruelly to prevent the Six Stars from gathering. As a final safeguard, should Ashura still awaken, he asked Taishaku-ten to kill him and consume his body, making Taishaku-ten strong enough to defeat Ashura. In Tsubasa Reservoir Chronicle, Ashura-ou is the king of the cold world of Celes. At the start of the manga, he is sealed in a magical sleep by Fay D. Flourite, who then flees through different worlds. It is later revealed that Ashura-ou rescued Fay from imprisonment in another world and raised him. Similar to his nature in RG Veda, Ashura-ou has another side in Tsubasa and regularly goes on killing sprees among his subjects. He took Fay in to draw his curse to kill everyone stronger than him upon himself, intending to die by Fay’s hands. (Source: Wikipedia)
