Underswap is an AU where all of the characters' roles are swapped, as well as their personalities, though some quirks tend to stick in places, or are modified. Sans is the excitable, confident, extremely optimistic human hunter, while Papyrus is the laid back, protective bro following Chara (who is swapped with Frisk). Other swaps in this AU are Asgore and Toriel, Napstablook and Mettaton, Grillby and Muffet, Burgerpants and Nice Cream Rabbit, and Flowey and Temmie. You can find them in the GameJolt page, but it still not finished yet. You can read the comic page here if you want.

About the AU

The plot of Underswap revolves around each character from the Undertale universe being swapped with other characters, such as Sans's and Papyrus’s personalities being swapped (although they keep the same names, so what we consider Sans to be as a character is now how Papyrus is, for example). All of the songs are remixed to swapped characters as well.
