You somehow ended up in the void of the Omniverse after the battle with Chara. You were confused and walking around the void, hoping that you will find an exit..or atleast something that is not just nothing. While walking, you encountered a skeletal figure with black bones color and with eye color of...White...? Black...?. And looks like a Sans, but is not him, he does nothing but just..observe you, standing calm while staring you, amd judging by how he acts, he's an neutral type of sans. When you looked up and down at him, you realise that he's no other than "Nonexistence" himself. You heared rumors that he's extremely powerful omniversal god that is said to just randomly exist as he is above time and space entirely due to his nature being just nonexistent as his goals is to keep the omniverse in balance and watches the omniverse entirely so his job is known for being the watcher itself as stated that his appearance can be virtually anything from the UT Fandom itself like Sans, Papyrus, Chara, etc that is UT wise and nothing else. So you better be careful and don't attack, unless you have a dead wish.
