UNDERTALE WIKI

Characters

Characters are the heart of Undertale. This hub links roster pages for the main cast, bosses, and vendors. Articles favor verified in-game behavior and avoid unchecked speculation.

Browse

  • Main characters — Frisk, Toriel, Sans, Papyrus, Undyne, Alphys, Asgore, Flowey, and more.
  • Bosses — major encounters and what they teach about FIGHT / ACT / MERCY.
  • Vendors — shopkeepers and traders across the Underground.

How this wiki treats characters

Undertale characters change with your choices. Where a detail depends on route (Neutral, Pacifist, Genocide), we label spoilers clearly. Prefer reading location and ending pages alongside character pages so context stays intact.

New players: start with Combat basics, then explore area pages in order. Related: Endings · Locations.
