Asura Otsutsuki (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.

  In the anime, Asura’s birth came with problems, which led to the untimely passing of his mother. Despite this loss, Asura’s childhood was peaceful and joyous, spending his time either blissfully alongside his father and brother, or playing with the village children. When old enough, the two began studying Ninshū under their father in the hopes of one of them becoming the great sage’s successor. As a child, Asura lived in the shadow of his genius older brother Indra. Having displayed no natural talent himself, Asura came to realise the value of others and the power of the friends and allies he made. Eventually, he awakened his own power which equalled Indra’s own. In the anime, despite still admiring his brother’s talents, he grew concerned for Indra as he continued to mysteriously grow colder and more distant to others.
