Ontos (Japanese: ウーシア, Ousia) is one of three units of the Trinity Processor in the Xenoblade Chronicles series.
Story
The Experiment
- Main articles: Trinity Processor and Alvis
On Rhadamanthus, Ontos was intended to act as an arbiter between the two other cores, Logos and Pneuma. When Klaus activated the Conduit, the world was split in two, with the Ontos core disappearing into another dimension alongside the half of Klaus's body that became Zanza, as well as Galea's body that became Meyneth. Some point after the world of Bionis and Mechonis was born, Ontos awakened as Alvis in Xenoblade Chronicles.
The Foundation of Origin

After the world's recreation following Zanza's death, Alvis returned to his Core Crystal, likely due to Klaus's death. Sometime after Shulk and Melia vanquished the Fog King from Alcamoth in Future Connected, Shulk came across the Ontos core on the shore of Colony 9.
When the worlds of Bionis and Alrest began to merge back into the original in Xenoblade Chronicles 3: Future Redeemed, Melia and Nia formed a plan to save the peoples and cultures of the worlds from destruction, constructing an ark known as Origin, which would contain all of their societies' knowledge and their citizens' literal souls, allowing them to be reborn after their worlds were reconstructed and then separated back into their original states. The Ontos Core was used as the foundation of Origin. However, this would lead to Ontos being reawakened at some point after Z hijacked Origin and created Aionios. As a result of Logos and Pneuma's absence, he reverted to being little more than a machine; as Alvis he was able to maintain a personality solely through his absorbing of Klaus' lingering regrets, but as a result of Klaus's death, that personality was lost.
Dubbing himself Alpha, Ontos would begin to execute a plan to create a new future by bringing the people of the City to a new world while abandoning Aionios and its inhabitants to die; the lives of the Kevesi and Agnian people, as well as Moebius, were deemed obsolete and unworthy of existence.
The personality and memories Ontos once possessed as Alvis would later manifest itself into a separate entity known as A, who would stand in opposition to Alpha and fight alongside Shulk and his allies once more.
Etymology
The name Ontos derives from the ancient Greek word ὄντος, meaning "one who is" or "being." The original Japanese name, Ousia, comes from the Greek word οὐσία, meaning "being" or "essence."
Trivia
- Each of the three biocomputers represents a part of the Holy Trinity. In Christology, Logos is a name or title of Jesus Christ, the Son. Ousia, in gnosticism, refers to the essence of God, the Father. Similarly, Ontos (or "ontology") can be related to the existence of God. Pneuma, in a religious context, is often understood to be the Holy Spirit.
- Additionally, each processor has its own bible verse from the Book of Proverbs inscribed on them in Latin, right below their names in Greek. They are 3:13 for Ontos, 10:12 for Logos and 4:18 for Pneuma, which is also written on her chest.[1]
- Due to the Trinity Processor not being introduced until Xenoblade Chronicles 2, in the original Xenoblade Chronicles, the necklace worn by Alvis holds a simple key with no importance. In Xenoblade Chronicles: Definitive Edition, the key was replaced with Ontos's core.
