Underswap is basically where all of the character's 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 Toriel and Asgore, Napstablook and mettaton , Burgerpants and Nice cream guy, Grillby and muffet ,Flowey and Temmie,and Undyne and Alphys .
Other swapped characters include:
Aaron and Shyren
Monster kid and Asriel

W.D. Gaster and River person
