Unused Moebius Theme
This section was kept within the game's files but went unused. It is similar in style to Moebius Battle 2 and shares sections of its melody with that piece, although it is significantly less bombastic. Its alternate unofficial name, "Moebius Area Theme", is because the section is conjectured to have been intended as part of a joint area-battle theme duo with Moebius Battle 2, in the same style as Tactical Action, Hostile Colony, and.

Moebius Battle (Climax)
This section does not play in-game (although the section from 7:09 to 8:04 is a fluteless version of Moebius Battle/M (Climax), which does play in-game). However, a release date trailer for Xenoblade Chronicles 3 featured this track.

Moebius Battle (End)
This section is the ending jingle for when a boss which uses Moebius Battle 2 has an action climax section (see below).

Dynamic nature and unreleased sections
Several tracks which are associated with Moebius Battle were not released, either as part of this track or elsewhere on any official release of this game's music. Specifically, Moebius Battle 2 uses climax sections (without a pre-end section) in several of its instances, which are similar to Moebius Battle (Climax) but not identical and which were not released. It is notable for being the only boss theme to use two different climax sections in different scenarios: In all cases, the climax threshold is 30%.
 * One, unofficially referred to as the 'Action Climax' (after the track's naming scheme in the game's files), plays for the, , , and Stage of Destiny instances.
 * The other, unofficially referred to as the 'Sad Climax' for the same reason, plays during the chapter 6 fight. This section has the same intro as Moebius Battle (Climax), but is otherwise different.

When a climax section is used, the track also has an ending section: Moebius Battle (End) in the case of the action climax, and the unreleased 'sad ending' in the case of the sad climax. A third ending, the 'action ending', was kept within the game's files but went unused and unreleased.

Trivia

 * The drummer, Maoki Yamamoto, broke his drumsticks playing the introduction to this piece.
