Song That Might Play When You Fight Sans

"Song That Might Play When You Fight Sans" is the 72nd track in the Undertale Soundtrack. It is a more intense remix of "sans.". This song is unused, leaving players to speculate that it was either replaced with "MEGALOVANIA," or made specifically to tease people and fool them into believing this song would play instead of MEGALOVANIA.

It is also possible that the song was intended to be used in a Neutral Route or True Pacifist Route battle against Sans, given its less serious tone. This is reinforced by its place in the soundtrack; it directly follows Undertale and is directly followed by The Choice, which suggests this song would have played in the Final Corridor before the player's judgment. It is also not considered a "hidden" song on the soundtrack, implying it would have played during a Neutral Route.

Trivia

 * This song is not actually in the game's files.
 * Much of this song is made with instruments from the SNES version of Mega Man X3, particularly its iconic guitar sounds.
 * This track quotes the melodies of "Nyeh Heh Heh!" and "It's Raining Somewhere Else".
 * The latter also quotes sans., making that another leitmotif.
