Undertale – Sans (Genocide Route)

In general, Undertale isn’t that tough of a game. Your true goal is to not kill all the monsters you come across to get the best ending. If you embark on the Genocide Route and lay waste to everyone, you’ll become so powerful en route to the Last Corridor that lesser monsters can’t even touch you. That is, until you face Sans. Mostly seen as a lighthearted dude, Sans is actually powerful, unleashing beams, bone attacks and much more. If you take up his offer for mercy, Sans will flood the player with bones until they’re dead. A bad time, indeed.
