Swaptale is an AU where Frisk is about to finish a neutral and a genocide route. Frisk is in the middle of sparing Flowey in the neutral route, and is fighting Sans in the genocide route. However, when Neutral Frisk presses MERCY and Genocide Frisk presses FIGHT, their timelines glitch out and they switch places, Neutral Frisk fighting Sans and Genocide Frisk sparing Flowey. Eventually, both of the Sans' realize something is up. Neutral Sans attacks Genocide Frisk and almost kills them, Genocide Sans has a talk with Neutral Frisk about his timeline. Neutral Sans gets killed by Toriel for attacking Genocide Frisk, but Genocide Sans somehow takes his place in his timeline, so everything works out in the end... or does it?
