Z

Z (pronounced "Zed") is the primary antagonist of Xenoblade Chronicles 3. He is the leader of the Consuls and is often seen in an old Amphitheater.

Appearance and personality
Z has long white hair with bangs, red eyes and pointy ears. He has purple cracks on his face and has horns made of purple flames on his forehead. Z wears a maroon Victorian-styled trench coat with silver trims with glowing purple lines running throughout, with pants and shoes of the same color.

Z usually calm, and acts in a logical matter, he believes in his "Endless Now" philosophy is the best course of action for mankind; Z is the self proclaimed ruler of Aionios. Z is also quite manipulative, convincing N to join his cause in exchange of bringing M back to life as a Moebius by telling him to slaughter the people of the City.

Story arc
Z is first seen during a meeting with the other Consuls after D returns from his battle with the party, discussing the flow of time, curious on how the flow will bring the party this time.

Z is later seen watching the party's progression at the Amphitheater on the screen with N, and Y, remarking that the eclipse draws near.

Z then observes a battle between Kevesi and Agnian forces on the theater screen while two Consuls plays what appears to be the Aionios version of chess before sending N off to Keves Castle.

Z is briefly seen in the Amphitheater after X saved N's life at Agnus Castle Barbican, issuing N new orders telepathically.

Z is featured in a series of flashbacks involving Noah and Mio's past selves, usually trying to seduce the former. He first appears in Noah's in a dream with him conversing with Noah after Mio's death. He is later seen killing Noah, Mio, and several soldiers from the City in Origin. In another flashback, he is seen in the Amphitheater watching Noah's and Mio's past selves. He then successfully seduces Noah into choosing the endless now philosophy, becoming the Moebius, N. In the last flashback, Z manipulates N into slaughtering the people of the city in exchange for bringing M back to life as a Moebius. When N initially refuses, he then attempts to dissolves M's body only for him to stop once N agrees to the task.

Z is seen with Y after an angry X returns to the Amphitheater after her scuffle with the party, complaining about how Noah has obtained the Sword of Origin which Z acknowledges. Just as X storms out the Amphitheater, only for Y to volunteer to go after the party, with X teleporting away as well.

After Noah uses Lucky Seven to destroy the Amphitheater, Z reveals his true form as a large face of dark energy which he can mimic specific people such as the party and his other Consuls. When he gained control of Origin, he is able to control its weapons.

Z is not an individual, but rather a concept. He is the collective form of Moebius; his Consuls are merely his avatars. However upon being defeated, he expresses hatred of the world.
