Xenosaga Episode III Edit
It serves as the last Omega boss when defeating Dmitri Yuriev and the post-transformed Omega. It virtually transforms into a powerful and formidable machine when Dmitri merges with it, along with the waveforms of U-DO that had infected him from his time of having direct contact with the entity.
After Dmitri/Ω Metempsychosis is defeated by Jr. and company, Albedo appears. The Zohar and Abel are extracted from Ω Metempsychosis and transported to Michtam (although the cutscene depicts Albedo doing this, a later cutscene implies "someone's will" did, likely Wilhelm).
The name "Omega Metempsychosis" is translated as "Omega spirit transmigration".
Episode III database Edit
The ultimate Omega configuration, a mutation that resulted from taking in the Zohar and completely reconstructing the Y-Data information. One of the relics of God.
The external transformation that occurred when it took in the Zohar stemmed from the self-transforming mechanism in the Omega waking up from its long sleep. It is thought that the Omega existed in a form similar to this configuration during the Lost Jerusalem era.
Abel has been built into the control device in the unit's core, due to the need for the higher-dimensional "power" flowing directly through the Zohar to be stabilized for dimensional space.
"[Omega] metempsychosis" can be translated as "Omega spirit transmigration."
- Like other mecha in the series, it is a recreation of a Xenogears design; in this case the Deus boss enemy from the end of the game. Where Deus sported two tiny angels, Omega Metempsychosis is accompanied by two lookalikes resembling Fei's Gear Weltall and Elly's Gear Vierge.
- According to the Episode III database, back at the time of Lost Jerusalem, an Omega machine was also created which nearly resembles Omega Metempsychosis, but was presumed to have been destroyed when Lost Jerusalem disappeared as a result from when the Zohar went out of control.
