Indra Ōtsutsuki

The Uchiha clan ancestor was the elder son of the Sage of the Six Paths. He was born with the Sage's "eyes": the powerful chakra and spiritual energy. He believed that power was the key to peace. When the Sage was on his deathbed, he selected the younger brother to carry on his dream of establishing peace throughout the ninja world. The older brother, believing his father should have chosen him, fought his younger sibling to try and claim what he felt was rightfully his. The elder brother's descendants, the Uchiha clan, would continue this fight with the younger brother's descendants, the Senju clan.

Appearance
He appears to be wearing a type of robe and had long black hair. While similar to the Rinnegan, the ancestor's eyes did not have the same ripple-like pattern of multiple ascending circles. Instead, his dōjutsu had a more spiral-like pattern.

Trivia

 * The older brother was born with the "eyes" of the Sage of the Six Paths. It is believed that his "eyes" laid the foundation or mutated into the two major doujutsu: the Sharingan and the Byakugan.
