Background
The Anomaly (also known as "The Player") is the being that controls Frisk during most of the time in Undertale. Whether the player decides to do Genocide, Neutral, or Pacifist, Frisk herself/himself cannot refuse it. Only during some instances does Frisk ever refuse it. They are shown to be canonical by the end of the Genocide route when Chara is talking directly to them when they re-open the game and when Sans mentions them in battle.
