RRRRREADY? IIIIIIIT'S SHOWTIME!!!
Mettaton, before transforming into NEO
Power of "NEO" is the 99th track in the Undertale Soundtrack. This short and repetitive track plays when the protagonist fights Mettaton NEO near the end of the Genocide Route. Its melody interpolates the opening notes of Battle Against a True Hero.
- The leitmotif was reused in BIG SHOT from Deltarune Chapter 2 and its OST, where it features a hidden boss.
