Dust Sans

Murder!Sans (also known as Dust!Sans) is a Sans OC from the AU Dusttale. This character debuted in an ask blog created by a user named Ask-Dusttale on February 10th, 2016. He was a regular Sans who, upon learning of what the human has done, aims to stop their genocidal actions by slaughtering all of the Underground to acquire enough LV to defeat the human.

In the original progression of Undertale, the player's interactions with the underground dictates how Sans behaves. This means that he changes depending on the "route" that a player runs: Neutral, True Pacifist or Genocide.

This story line follows the possibility of the player abusing their ability to reset the timeline to repeat the Genocide Route as many times as they want.

Sans the only character that shows awareness of the player's ability to reset time and revive themselves after death. In this take, it is that same acute sensibility that causes Sans to realize the underground has been reset and slaughtered repeatedly.

His response to this realization is to beat the player to the punch; he slaughters the entire underground himself, including his brother Papyrus, with the intent to gain enough power to stop the player from completing another Genocide Route.

This series of actions drives Sans to madness, causing him to hallucinate the specter of his deceased brother.

Dust's appearance slightly deviates from the original design. He wears a blue hoodie with a grey hood, of which he keeps up, black shorts with white lining and a pair of gray slippers. His bad time eye is the only thing that truly differs, having changed color from a blue and yellow to a blue surrounded by red and even having a second red magic eye. He is usually depicted as having grey dust coating his clothing.

Before the human arrived in the Underground, Sans was more of a lazy and friendly skeleton who would often make jokes. He would go to Grillby's for a good amount of time; he was very caring about his brother, Papyrus. However, after the human reset and did numerous Genocide Routes, one day due to unknown circumstances Sans suddenly remembered all the Genocide Routes. This changed Sans, and made him kill other monsters for LV; even going as far as killing his own brother. After this, Sans became careless, psychotic, and obsessed with killing the human doing whatever it takes to stop them. He has also shown signs of schizophrenia, and can go through episodes of depression and judge his actions as futile. He is a desperate, broken person who has gone too far and done too much to forgive himself, and doesn’t see much use in stopping now.

Papyrus: Papyrus is Sans's younger brother whom he slaughters in the hopes of gaining more power to defeat the player. The killing of his brother was a great breaking point of his sanity, and after that began to have a constant hallucination of Papyrus who frequently goads him to achieve his violent goals, Papyrus also often mocks and berates Dust.

He's an alcoholic and smokes.

Killer: Loud and annoying right-hand man, addicted to knives and collects them, undoubtedly loyal to Nightmare alone, is an outright bastard who never stops smiling, cruel. (White ashy bones, black and white target in front of chest- his literal algamation of a soul. Hollow sockets, liquid HATE constantly seeping out of them down his cheeks.) Uses both fighting skills, agility, knives, and magic knives to fight.

Dust: Quiet and aggressive, smokes and drinks often, truly unhinged, schizophrenic. Speaks to a ghost of his brother he killed, Papyrus, aka Paps. Wears his hood up constantly and had mismatched teal and red ringed teal eyelights that glow dimly under the hood. Unlikely for conversation, more likely to kill someone and move on. (White bones, not as short as Nightmare.) Uses his magic to fight strictly, has insanely high LV, which you get from killing.

Horror: The muscle, tall and wide, quiet and prone to mumbling. Has a large hole in his skull, causes him to be unpredictable and have mood-swings, but is the most stable out of them all. Often manhandles anyone in reach, has an affinity for cooking and is food-sensitive due to a past of starvation. Right socket is lidded and dead, left is swallowed by a round red eye he stole for himself. Dangerous and hates humans like the others, but is good for cuddling with the others. Uses his axe to fight, swings hard and fast.

Nightmare: The boss, gives off strict and eldritch horror, a father figure of sorts to his boys behind doors, quiet and deadly and flamboyant. (Black bones, four black tentacles on back which can be used as tools and weapons, right eye govered in the black substance, left eye a lidded teal eyelight, short.) Uses his magic to fight, mainly his tentacles. Cold and cunning, nobody is smarter than he is. Nearly 500 years old.

Nightmare's Gang, The Bad Sanses (Which Dream and the Stars fight against):

Nightmare wants to rule the multiverse, the stars try to stop them and fight them.

Dust's views on the gang: Nightmare- The boss. Shut up and listen to him, whatever you do, don't piss him off. Wouldn't kill them, but would give them a good whack on the head, those tentacles hurt. Killer- Annoying dipshit, but Nightmare's right hand. Dust wants him dead often but can't kill him without getting in serious trouble. Horror- A lot more tolerable, oddly pleasant to be around and makes sure everyone eats. Good idea to be on his good side. Paps/Phantom- A hallucination. He knows this. They all know this. He'd rather fight someone than admit it.
