Indra Ōtsutsuki

He was the elder son of the Sage of the Six Paths.

Background
He inherited the Sage's "eyes", his powerful chakra and spiritual energy. He believed that force and strength were 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, angry and jealous that his father had not chosen him, fought his younger sibling to claim what he felt was rightfully his. The elder brother's descendants, who would become 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 his eyebrows seemed to be clipped short, a sign of nobility in ancient Japan. He had long black hair with two locks wrapped in bandages framing either side of his face and his eyes were turned up at the corners, with marking under them. While similar to the Rinnegan, the ancestor's eyes did not have the same ripple-like pattern of concentric circles. Instead, his dōjutsu had a more spiral-like pattern and as shown in flashbacks, appeared to be red in colour similar to the Sharingan. It is unknown what the name of this dōjutsu is or what techniques it had.

Trivia

 * The older brother was born with the "eyes" of the Sage of the Six Paths. It is believed that his "eyes" either laid the foundation for, or mutated into the other two major dōjutsu in the ninja world: the Byakugan and the Sharingan.
 * His deep seated hatred of his brother because of his father's decision transcended down throughout his lineage and became known as the "Curse of Hatred".
