Asura Ōtsutsuki (大筒木アシュラ Ōtsutsuki Ashura) was the younger son of the Sage of Six Paths. Though he wasn't the first choice as successor, he ended up inheriting his father's mantle instead of his brother Indra. This led to a bitter feud between the two and also their descendants. Asura is credited as being the progenitor of the Senju and Uzumaki Clans. Throughout history Asura and his brother would go through the Transmigration Cycle, reincarnating as various individuals, such as Uetto Senju, with his most recent being Naruto Uzumaki.
