Undertale Character Ages ChartĪs mentioned, there’s no official record of the ages of the Undertale characters. With every detail we can gather about each character, we can then deduce how old they are. Each character has characteristics and other details that hint at experience and personality that come with age. That said, the best thing we can do is make an educated guess as to what each character’s age is.
We can simply look at the facts the game presents to us and formulate our own assumptions.
First things first, it should be noted that there is no official or canon record of the characters’ ages in Undertale. Be that as it may, the fact that there is no canon record of this makes the discussion itself all the more fascinating.
