"Sans is Ness" is an ironic reference to "Game Theory: UNDERTALE - Sans's SECRET Identity!", a controversial video by YouTuber MatPat about the secret identity of the character Sans from the video game Undertale.

Welcome to Game Theory Edit

Matthew Robert Patrick (born November 15, 1986), commonly known by the nickname MatPat, is the creator of several popular YouTube channels. His biggest channel is The Game Theorists, which features a web series called Game Theory. Created and narrated by MatPat himself, Game Theory showcases theories about various aspects of famous video games, including speculations about hidden messages and subtexts allegedly present in video game lore.

Despite the immense popularity and success of Game Theory, many are also critical of the show and MatPat. One common criticism is that the show presents theories and claims without providing enough evidence or research to support them. (i.e. "Why Mario is Mental", "Mario is Communist?", "Wario is ten feet tall")

Just a Theory Edit


MatPat, creator of Game Theory.

On February 9, 2016, a video titled "Game Theory: UNDERTALE - Sans's SECRET Identity!" was uploaded to the Game Theorists YouTube channel. In this video, MatPat postulated that Sans from Undertale is Ness, the protagonist of the game EarthBound (or more specifically, the version of Ness from Earthbound: Halloween Hack, a hack of EarthBound created by Toby Fox, the creator of Undertale).

MatPat's video was widely criticized for making far-fetched conclusions, having logical errors, and ignoring evidence that didn't support the theory. He later addressed these criticisms in the video "Game Theory: Who is W.D. Gaster? (Undertale)", arguing that it was just a fun exercise for him and that he never truly believed it himself nor expected it to be taken that seriously.

But Hey Edit

In SiIvaGunner's high quality video game rips, ironic references to MatPat's aforementioned theory have become a meme. This meme can manifest in several ways:

  • Using Undertale tunes in EarthBound rips, and vice versa.
    • More specifically, using "Megalovania" (which is associated with Sans) and "Onett" (which is associated with Ness).
  • Having Undertale tracks segue into EarthBound tunes and vice versa in medley rips.
  • Using Game Theory's theme tune ("Science Blaster" by SpellingPhailer).
  • Featuring exerpts from "Game Theory: UNDERTALE - Sans's SECRET Identity!", as well as other Game Theory episodes.
  • The appearance of the fusioned character born from this theory, referred to as Sens.
