Undertale Headcanons

667: Toriel made all of the puzzles you find in the Ruins. She decided to make them after Sans described Papyrus's love of puzzles.

666. Frisk was sleep walking the whole time.

Who's ready for 666

665. Frisk is a blind child, which would explain why were they holding a stick at the beginning. They fell into the mountain on accident, and Chara, seeing them like that, decided to help them telling them what’s going on.

664. Undyne and Papyrus are in a queer platonic relationship

663. In one particular timeline that isn’t in the game, Frisk actually talks and laughs. Sans falls for that laugh and their voice, and can never forget it through every timeline. That’s why he’s always telling puns. He’s trying his hardest to make the silent one laugh again, smile again… Be themself again.

662. Frisk, like Flowey, is extremely good at imitating voices.

Nearing our 666th post! Send us your your darkest headcanons :)

661. The Temmies’ weirdness is all an act and they’re actually masterminds indirectly controlling every little thing that happens in the underground

660. Papyrus is lactose intolerant, Alphys is allergic to shellfish, Asriel was gluten-free, Chara was allergic to cats, and Asgore is allergic to mold.

659. Along with anime, Alphys finds Marvel comics in the dump. She doesn’t take too much interest in them, and gives them to Undyne. These are what inspire Undyne to join the Royal guard and become her own type of “Superhero.”

658. Once Undyne gets to the surface, she sees the real Internet. She becomes a total memelord, and poor Sans can’t go near her without hearing, “DAMN SANSIEL. BACK AT IT AGAIN WITH THE WHITE VANS.”
