Character in Xenoblade Chronicles 1. An enigmatic man who meets Shulk in Makna forest, and is later revealed to be a seer who serves Sorean Antiqua. He knows much about the Monado. This is because he is the Monado.
Is actually a manifestation of the administrative computer at the First Low Orbit Station. The next game as well as the remaster implies that he might be Ontos, one of a trinity alongside Pneuma (Pyra and Mythra) and Logos (Malos) as well as the core who was sent in a different dimension. His remastered appearence gives him a red Aegis core crystal very similar to these two.
He reappears in Xenoblade Chronicles 3: Future Redeemed as an apparent antagonist. Sorta kinda. At the very least, his XC1 form is used as Alpha's default form, who is basically Ontos's pure logic devoid of humanity. In fact, the part which consists of Alvis' actual personality splitted into a different body named "A".
