Horror!sans

However, after his skull got broken and a part of his magic was taken by the now insanely violent Undyne, something within Sans changed. Sans instigated a new rule by Undyne, where humans who fall down are to be consumed for survival. After this, Sans was no longer the joyful skeleton he once was. According to the bunny, despite the rule he himself implemented, Sans has not eaten anything for 7 years, which then led to him losing his kindness, along with his sanity. After many years of hunger Sans is seemingly bored of everything, even though the dire situation has damaged his psychological state severely, as he now seems to enjoy psychological humor and every bit of Aliza's screams. Whether it be Papyrus's puzzles or the hungry people of Snowdin or even himself torturing her, he has no sense of morale or seems to care about right or wrong; his jokes have changed from annoying yet funny to dark, insane and sadistic, reflecting his attitude ⚜️Have fun⚜️
