I implore you, play the game before reading this, as this post [may] contain SPOILERS. It would sadden Toriel if you were to ruin the game for yourself, and when Toriel is unhappy, I am as well. Please, do not upset me...

TL;DR

=
====== Toriel: 23-58 Asgore: 23-80 Asriel: 8-18 (Likely Max. 17) Frisk: 8-18 (Likely Min. 9) Chara: 8-18 (Likely Min. 9) Alphys: 20-30 (Likely Max 25) Undyne: 20-30 (Likely Min. 25) Sans: Indeterminate (A conundrum wrapped in an Enigma with a Side of Entropy...) Papyrus: 18-28 (Likely 19) Dogs: Indeterminate

====== NOTE: For characters who arguably do not age, this HeadCannon will ignore 'actual age' and instead focus on 'relative age'. Additionally, this DOES NOT cover all characters (It is only a PARTIAL HeadCanon after all).

Torel refers to herself as an 'old woman' in one of the "Flirt" cell phone exchanges... but according to Gerson, Boss Monsters only age when they have a child. Since Asriel is essentially dead, Toriel and Asgore have since stopped aging. Asriel died when he was somewhere between 8 and 18 (This also fits with the game's plus or minus nine year margin of error as implied by the '201X' theme [unless the X means 10 in which case the year would be 20110, but that's a whole different HeadCanon that I may or may not actually get to]), as what we can assume to be his Ghost is still wearing a Striped Shirt (Mini 'Striped Shirt' HeadCanon below). According to the Monster Kid in Snowdin, this indicates he was still a Child at the time. Given this, reasonable ages for Toriel when she stopped aging could be anywhere between the extremes of 23 and 58, putting Asgore in the reasonable range of 23-80. These age ranges are incredibly broad, and take into account the fact that Monsters may mature differently than humans, possibly reaching 'adulthood' earlier or later than a human of the same age would (Mini "Family-Based Aging' HeadCanon below).

Many HeadCanons have established that Alphys and Undyne are both between 20 and 30 years of age (With evidence pointing to Alphys possibly being the younger of the two), which I can find no argument against. Additionally, in other HeadCanons, Chara is assumed to be the same relative age as Frisk. Due to their Striped Shirts, this puts them in the same age range as Asriel at 8-18, being possibly a year or two older when compared to Asriel (Since Asriel has been shown to somewhat look up to Chara despite her not-so-nice nature). Sans, outwardly, lacks a striped shirt, but who knows what's under that hoodie of his. This makes his age (as with other HeadCanons) Indeterminate. Papyrus, however, only appears to have a few outfits, none of which include a 'striped shirt', not to mention he is taller than the Protagonist and Sans. Papyrus, therein, could be as young as 18 or as old as 40. He is shown to see Undyne as a rolemodel, so it's more likely that he's as young as 18 or as old as Undyne minus one or two years, for a final range of 18-28. The most likely age for Papyrus would, by this measure, be 19. I'm not even going to bother with the Dogs; dogs ages are fuzzy enough as is, and it would take INSANE amounts of Logic to pin them down, especially if one factors in the conversion from human to dog years.

Mini HeadCanon: The Striped Shirt

=
====== I'm not positive about this, but I'm pretty sure I saw more stripes on Asriel's shirt than on Monster Kid or Frisk/Chara's shirt... could Stripe Count be tied to Age...?

Mini HeadCanon: Family-Based Aging

=
====== A monster appears to age to Adulthood, in the 25-35 year range, and then stop aging. If they have a child, the aging process will resume until that child reaches adulthood. This would result in a very consistent age gap between generations, as each new generation would push the rest of the family tree up proportionally.

So what do you think? Feedback is always appreciated.
