Author: Have you heard of Underswitch? If you have, you will be interested. If you haven't, it's my fan made A.U. were Don is Sans, Papyrus is Don, and Sans is Papyrus (Kind of like Underswap Sans but purple.) Everyone knows Killertale where Sans is possessed by Chara, right? This is basically the same but Don instead of Sans. Don't die. *Reader goes through a portal*
