Birdtale — This is an AU (Alternate Universe)of the game Undertale. This may contain spoilers for Undertale, so if you have not played/ watched the game Undertale... DO NOT READ THIS!


There are two different types of Birdtales, I will be focusing on one, the AU where all the characters have wings of a certain bird. The other AU is just that the characres are replaced with birds. In Birdtale, everyone has bird wings and at times bird tails. Usually their personalities do not change, but most of the outfits main characters wear are suited to be well in air. Most outfits have goggles, like Sans and Papyrus.


Frisk (Long-tailed tit)

the only walking character who does not have wings. One day, while walking on the rocks of a mountain, Frisk stumbles on some roots near a hole and falls into it. She spared all of the monsters she met, because she had a good soul.
