Leitmotifs

A leitmotif is a musical "phrase" or melody, re-used in multiple songs to associate a tune with a person, event, or place. Leitmotifs occur several times in the soundtrack of Underverse.

Original Leitmotifs

Cross' Theme

As the name suggests, this is the leitmotif that accompanies Cross. It was originally a short loop created by Jakei, but ended up getting remixed by NyxTheShield multiple times and never actually used. It can be heard in some specific tracks in Underverse, however.

• Cross Theme V1
• Cross Theme V2
• Cross Theme V3
• Cross Theme V4
• Hope – 0:00-0:10
• Unreleased 0.2 Music – 13:27-13:39
• Crossed Souls – 0:04-0:46, 1:29-1:37

Overwrite

This leitmotif typically has to do with XChara. It originally started as an original track by NyxTheShield, but ended up being reused for Underverse.

• Fulfilled Presage
• Extinguish
• Twisted Spectacle
