This article is about an AU that has been deemed community-shared, either by the author declaring it, or from long-term abandonment by the author. For elaborated information on community AUs, see the Templates policy page.

Outertale is an AU where Undertale is in a space setting instead of Underground. The characters all have star-themed attire, attacks, and themes (music). There are many capes and long draping clothes, much of which is white, gold, and deep blue like the night sky.

The official canon of Outertale is stated to follow the exact same theme as the Undertale game’s playthrough. However, unlike in Undertale, the human vs monster war resulted in monsters being banished into space (specifically on a moon) instead of the underground.[1]

Essentially, the Pacifist, Neutral, and Genocide routes apply here as well, and character personalities are the same as they are in Undertale.

Monsters turn into stardust when they die.

Characters

Frisk

Still the main protagonist, Frisk crash landed into the Ebott Quadrant. They are one of the humans that has done that in the past.

Twinkly Twinkly

Instead of being a flower, Flowey takes on a whole new role by being a star. But still has that sinister aggression towards the player.

Toriel

Toriel is one of the major characters of Outertale. She saves the protagonist from Flowey and guides them through the Caverns.

Sans

Sans is the older brother of Papyrus and a major character in Outertale.

Papyrus

Papyrus is one of the main protagonists in this AU and, as in most other AUs, he is the younger brother of Sans. He is also very similar to his Undertale counterpart, since he is also extremely annoyed by jokes and puns. Outertale Papyrus and Undertale Papyrus are almost identical in every aspect besides their clothes.

Undyne

Undyne is still a Boss fight in Outertale. She wears something similar to her normal outfit in Undertale and still becomes Undyne The Undying in Genocide.

Alphys

Alphys is still the Royal scientist for Asgore. She is also a space-based anime fan, as well as a sci-fi nerd.

Mettaton

Mettaton is still a robot with a SOUL and was built by Alphys. Initially poised as an entertainment robot turned human-killing robot, it is later revealed that he only acted as such. Mettaton is the sole television star of the Ebott Quadrant as he is the only "star" on the planet.

Asgore

Asgore, just like in Undertale, is The King. He has the same personality.

Asriel

Asriel Dreemurr is the biological child of Toriel and Asgore and the adoptive brother of the first human. He serves as the final boss of the True Pacifist Route, just like in Undertale.

Chara

Chara was the first human to crash-land in the Ebott Quadrant. Chara is also the human that the player names at the start of the game, not the controllable character who is played throughout the entirety of Outertale.

Trivia

Character Designs

  • Mettaton’s heart is gold and glittery encased in stardust.
