He is also the creator of the sharingan similar to how Rikudo was the first bearer of the rinnegen eyes. He fought rikudo to see whos eyes were stronger sharingan vs Rinnegen. It was the clash of the mellinium It destroyed half of the world by using shinra tensei vs metatrona, shinra tensei won and the result was he used to much chakra on that shinra tensei ( which later become the moon ) the end result was he died.
