Overview
Fight Sans from the Underswap universe! Underswap is a universe where all the characters from Undertale that somehow connected to each other are reversed their roles, so, Papyrus and Sans are an example of this! Now Sans is the younger brother with his ambitions, not Papyrus, but still their characters have remained the same as in the original universe. Sans wants to fight you fairly, purely for fun :) You can try spare him and then see a different outcome of the fight! Have a nice game!
