Versotale is an Undertale Role-Swap AU where instead of the humans winning the war, the monsters won instead.
- The Protagonist/Player Character Role is taken by Asriel, having a voice and a personality based on the combination of Undertale Asriel and Flowey's.
- The Empty One Role is taken by Asthana, a notably friendlier flower.
- The Caretaker Role is taken by Frisk, a punny jokester who always worries that things will eventually go wrong.
- The Fallen Role is taken by Undyne, a more aggressive and distrustful narrator.
- The Ruins is replaced by the Perditus Borough. It has the same layout as the Ruins, but Frisk replaced the puzzles with riddles for safety.
- The Barrier requires Monster magic to be broken.
- Techna named the AU Versotale because it is the reverse of what happened in Undertale.
