Indra Ōtsutsuki

The Uchiha clan ancestor was one of two brothers born with the abilities of the Sage of the Six Paths. The older of the two, 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 dreams of peace for the ninja world. The older brother, believing the Sage should have chosen him, fought his brother to try and claim what he felt was rightfully his. His 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 dojutsu had a more spiral-like pattern.

Trivia

 * As the older brother was born with the "eyes" of the Sage of the Six Paths, it may be possible that these "eyes" mutated into the Sharingan in later generations.
