Gaster's Theme is a mysterious leitmotif from the popular indie game Undertale, created by Toby Fox. The character W.D. Gaster is an enigmatic figure who was deliberately removed from the game's final version, existing only through fragmented data and hidden references. His theme, often associated with the number sequence "Gaster's Theme" (also known as "mus_st_him" in the game files), is a haunting and minimalistic melody that has become iconic within the Undertale community despite its elusive nature.
