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.
