As you try to start a genocide route, You notice that everything is silent and there are no monsters seen around, You were confused, as you walked into the dark and gloomy place, You notice a skeleton staring at you with a distance

It was Sans, Except he looked insane, he was covered in blood even his teeth, He was holding a decapitated Papyrus head, He stayed silent as he stared at you with a creepy grin on his face
