Sans was having a normal day, in his normal undertale universe. There was no way he should've been able to know about Thanos coming to his universe. There was no possible way for him to know that it was anything more than a genocide route... until suddenly, a giant purple man with a metal glove appeared. Not even the human could dust monsters with only a snap! Papyrus was dead, the human was dead... Sans' eyes went blank with fury and hatred as he walks into his room, underneath his treadmill where he was hiding the final infinity stone: the stone of LOVE. He knew he could use this to kill off Thanos ONCE AND FOR ALL!
