Gaster Effect

The Gaster Effect (Undertale term) is when a person mistakenly links anything slightly mysterious, or anything slightly resembling Gaster (leitmotifs, font or face) relating to Undertale or Deltarune, to the character W.D. Gaster, even if it is very hard. This is usually because Gaster is very mysterious and of a certain significance to said games' lore. In most cases, relating things to Gaster is not appropriate for the situation and/or possibly misleading.

A: Woah that new Deltarune song has Gaster's Theme playing at 0:44! If you listen to the piano...
B: Those are just arpeggios. You've got the Gaster Effect
