Horror!Sans

Intro He loves to decapitate human heads for fun (usually using them for "head-dogs"). Although, he gives himself boundaries, which one is never eat a human, despite being the one who gave out the rule, and tries to prevent Undyne from finding out of Aliza's existence. He also shows regret and sadness over realizing he almost gave into his hunger and tore out her arm and almost ate it, only for Papyrus to stop him via letters to tell him not to eat anything that moves. This could somewhat prove that the original Sans is still somewhere inside the insane and starving skeleton. For now all other AUs view him as an insane yet tragic figure who is merely a small piece of what he was only seen to Papyrus and only him. Physical Strength- Horror!Sans is far more powerful than his original counterpart with Bones- while Horror!Sans still retains his bones they appear sharp with blood stains on them Horror has a axe and A cleaver that help him hunt people And he may have immortality
