Toby Fox Wikia

This is it, the final boss theme. I wanted to put Live A Live's Megalomania in here but I didn't get to so I made my own last boss song. I pretty much just yelled whatever I felt like into a mike and copied it down. Yep. Took forever, but it was superkickass-worth-it. Total embodiment of final bossitude.

Megalovania is a track composed by Toby Fox which has since appeared in numerous projects to which he has contributed.

  • Megalovania is a portmanteau of "megalomania" and "Transylvania".[2]
  • The Rony Roller Circus Troupe performed an orchestral version of Megalovania for the Pope in a weekly Vatican meeting in mid-January, 2022.
  • Another version of the track appeared in Mother: Cognitive Dissonance (which Toby was not involved with) called Megalovania - Clash with a Doctor.
  • The track Megalo Strike Back Toby created for the EarthBound fan album I Miss You - EarthBound 2012 is commonly believed to be a "sequel" to Megalovania, as it has "Megalo" in its name, and uses the same guitar sample from EarthBound. The connection is unconfirmed by Toby.
  • The version found in Undertale and Super Smash Bros. Ultimate is in the D Minor Blues/Pentatonic[citation needed] scale, whereas all other mainline versions (MeGaLoVania and the EarthBound Halloween Hack) are in A minor Blues/Pentatonic[citation needed].
