"What you see over there...it's not Z or Moebius, but a single, intense desire."

— M

Z∞ is the final Boss of Xenoblade Chronicles 3. This is Z's true form, and is a Moebius fought at level 75 in Origin. After defeating the first phase, Z∞ will split the party into two groups, forcing Noah, Lanz, and Eunie to fight X∞, and Mio, Sena, and Taion to fight Y∞. After both are defeated, the party resumes the fight against Z∞, with Nia and Melia arriving to fight alongside the party once they bring him down to 50% HP. During the second phase, whenever the player uses a Talent Art, either Melia or Nia will follow up with their respective Talent Art if they are present.

Appearance

Z∞ is composed entirely of purple Moebius energy. It takes the form of a giant version of Z's head with long hair that act as tentacles, and planted in a purplish void with ever-moving energy particles. It maintains the facial cracks and energy horns of Z, this time manifested as white "flames" or voids. The inside of Z∞'s face is also a white void. It's eyes are red. In cutscenes, Z∞ shifts its appearance to mimic the faces of others.
