Chaos!Sans is an oc made by alimaxxe. He's a being born from the antivoid. He currently wandering across the Multiverse causing Chaos.


a very, very long time ago, when the multiverse was still a newborn, a being started to rise from nowhere, he was lost in the antivoid, lacking a soul, but having extreme powers, after staying there for a long time, he discovered the au hop, he then teleported outside the antivoid, he started feeling immense pain in the chest, then, the frisk of the universe, being in a genocide run, tried to kill him, so by self defense, he punched they, when he punched they, their soul was absorbed by chaos, he started to no longer feel pain in the chest, started feeling better, and when he saw the human dying, their pain.... gived him joy, flashforward to tomorow, the chest pain is back, chaos realised that to survive, he needed to absorb human souls to survive, and day after day, he started becoming more and more crazy, until a point where he started killing people for fun, and sometimes spared them when they where about to die to see their pain, he also gained very... unique powers from all the murders and started wandering around the multiverse



chaos looks like a normal sans, except his colors are completely random and every part of his body/clothes changes constantly, his eyes always stay orange and pink tho


chaos is completely crazy and impossible to save, he will do any inhuman act just for fun and won't hesitate a second to kill for fun, he also lacks a soul, making it impossible for him to feel any emotions, but when he absorbs a soul, for a second he acts like a normal person, but it litteraly lasts 1second
