Asura Ōtsutsuki

Asura Ōtsutsuki (大筒木アシュラ, Ōtsutsuki Ashura) was the younger son of Hagoromo Ōtsutsuki. Though not the obvious choice to most, he would go on to inherit his father's teachings, and as a result, would have to clash bitterly against his elder brother Indra. Asura is also credited with being the progenitor of both the Senju and Uzumaki clans.
