Burai: Zyuranger's Tragedy

This is Zyuranger respectively. His story starts as the son of the Black Knight and the brother of Geki the Tyrano Ranger. Unlike in MMPR, he has his powers from the start and he was only eight when he saw his baby brother being given to the Yamato King and later his own father die. Swearing vengeance, he was consumed by the darkness present in him that it resulted him to hating his younger brother. He was put into suspended animation in a cave which one day, Ryota a member of ancient mankind released him which caused so much trouble. He nearly destroyed Daizyujin from within while it had trouble battling Griforth...
