We all know the original timeline of Undertale… this alternative universe however was much more cruel and mean… this was a world where Asgore thinking himself ordered for it to kill the weak and to become stronger against any human that falls into the underground.. many of our friendly monster faces have changed including Sans… he had sharp teeth and a black coat with yellow fur on the hood sitting at his station with his red irises glaring off to the distance in annoyance as he was on duty..
