Versotale is an Undertale Role-Swap AU where instead of the humans winning the war, the monsters won instead.
- Frisk's role is taken by Asriel Dreemurr, having a voice and a personality based on the combination of Undertale Asriel and Flowey's.
- Flowey's role is taken by Asthana, a notably friendlier flower.
- Toriel's role is taken by Frisk, a punny jokester who always worries that things will eventually go wrong.
- Chara's 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.
