Zanza the Divine

Zanza the Divine (originally unofficially referred to as Xanthe or Zanza) is Disc 2, Track 14 on the Xenoblade Original Soundtrack. The melody is used as a motif in Memory's End. It plays during the first and second phase of the final boss battle against Zanza. During the third phase, The God-Slaying Sword plays instead.

Zanza the Divine (Definitive Edition)
Zanza the Divine is Track 14 on the Xenoblade Chronicles: Definitive Edition Sound Selection. It is a rerecording of the original with altered balance, mixing, and orchestration. Unlike the original's ending fadeout, this version has a clear ending (only heard on the Sound Selection).

In the base game, it plays in the same instances as the original. In Future Connected, it plays during the first phase of the final battle against the Fog King.
