Last Breath Genocide - If the game records you doing genocide 99 times in a row, the next 100th playthrough will be  a Last Breath. (OST 100 is MEGALOVANIA lol) (You could add Dusttale or something else before 100) Sans realizes he needs to put more effort in stopping you and convinces evryone in the underground to group in teams. You have to fight multiple bosses together. Some of the bosses run away to live to fight together in the last battle. They use the souls to maximizee their power and offer a pretty challenging fight.

Genocide routes seem kind of unfulfilling to write
