Sans/Straytale

Tainted Sorrow Sans is a version of Sans from the AU Straytale, who had undergone special experiments by one W.D. Gaster. He ends up pushing his Gaster into the Core, and ends up being a bit more outwardly gloomy and frustrated than usual.
He's also vaguely inspired by Chuuya Nakahara from Bungou Stray Dogs.
== Backstory ==
In this story, the fall of W.D. Gaster is a... slightly more complicated matter.
Alphys was not the first to experiment with injecting determination into monsters. No; Gaster, the genius that he is, had thought of it long before. However, he also realized far sooner just how incompatible monsters are with determination. He didn't quite realize that it was a case of insufficient physical matter, though. No, what he thought is that determination and magic may be inherently incompatible with each other. This led him to try mixing magic with determination directly... and he succeeded. He succeeded far more than he could've imagined.
This was the beginning of Project Arahabaki, and for it, he brought over a companion of his named Sans. They both worked tirelessly at the new substance that Gaster had inadvertently created. This new power could be the key to monsterkind's freedom. However, when injected into dead or dying monsters, they would just perish on the spot. A healthy subject would be needed. Sans volunteered himself for it, and as Gaster prepared himself to inject Sans with this new power, the royal scientist spoke a piece of a poem to himself to try and prepare for the worst.
"To thee, the granting of a gloomy corruption; may ye never awaken again."
Upon being injected with the power, Sans underwent extreme levels of pain. Black and red markings crawled over his body, and Gaster didn't know what to do... or what exactly was happening. Suddenly, Sans got up, staring right at Gaster with black-and-red eyes, and an expression of irrational rage and hatred.
Thus began the brief chase. Sans hunted Gaster down all throughout, until they eventually reached the Core. Sans punched Gaster directly into a wall, seemingly nothing beneath him but a white abyss. Gaster, upon beginning to drop, summoned one of his Gaster Blasters to act as a platform and keep him up, but then, Sans rose up above him with a gravity sphere in hand. He threw the orb directly at the royal scientist, and incapable of discerning how powerful it was, he ended up being pushed into the Core's depths by it.
Thankfully, Gaster had prepared for damn near everything. Most of the chase was merely wasting time, and suddenly, 5000 volts of magical electricity surged through Sans' body, shocking him out of his out-of-control-state. Sans had allowed Gaster to implant a chip in his skull, which would zap him and knock him out if he ever lost control of this power for more than five minutes. He could just barely mutter out a "thank you" before passing out.
Ever since then, Sans lived a very similar life to his canon counterpart. He lives with his brother Papyrus, annoying him with his constant puns and other such jokes. He sometimes chats with Toriel over the door to the Ruins, sharing puns with each other and making all sorts of lofty promises. And in general, he's just trying to live life the best he can.
But above all else, he hates the idea of losing control again...
== Appearance ==
He generally looks nearly identical to the classic version of Sans, albeit with a few differences. His shorts are solid black, lacking the white stripes of his canon counterpart's. His hoodie, meanwhile, is brown with a black hood. He also wears black sneakers rather than pink slippers.
His "bad time eye" is still blue, albeit fading to red near the pupil.
== Personality ==
On the surface, he seems identical to the classic Sans. He's a guy who loves pranks, puns, and his dear little brother who's somehow far taller than him. But then you look just slightly deeper, and you see someone that is surprisingly aggressive when pushed. He's very serious about his job as the judge, and his role as Papyrus' sole legal guardian, and if you infringe upon either of those, you won't have a good time. Hell, you'll have an even worse time than with the canon one, as this one would just barely be able to restrain himself from beating you up on the spot.
More than anything else, he's scared of his power. He's afraid that, if he ever loses control again, he'll end up hurting Papyrus and everyone else around him. That just adds to his apparent laziness, as he would rather do nothing than exert himself only to make things worse. 
== Abilities ==
* Bone Magic: Sans is able to conjure bones from the air or from any surfaces around him, and control them at will. He can also make them blue, forcing the opponent to stay still in order to not get hurt.
* Blue Soul Magic: Sans is able to turn the target's soul blue, at which point he is able to control its gravity at will. This is a decent alternative to his new abilities when he doesn't want to exert himself too much, but otherwise, he prefers said new abilities.
* Shortcuts: Sans is able to teleport anywhere he's been to before.
* Gaster Blasters: Sans is able to summon floating skull-like weapons that fire beams at his target.
* Gravity Manipulation: Originally, Sans' powers over gravity were limited to beings with souls, due to the aforementioned ability interacting with the soul first and only controlling the target's body as an after-effect. However, with his new power, he is able to control the direction and force of gravity in anything he's in contact with, possession of a soul be damned. This grants him an immense level of versatility, as even the ground beneath his feet is now able to be used as a deadly weapon. Tiny pebbles picked up off of the ground can act like bullets with sufficient gravitational force behind them. Massive boulders can be pulled out of the ground and thrown at the opponent at mach speeds, or masses of smaller rocks can be used to bind the target. He can shatter a pane of glass before utilizing the shards as a flurry of blades. Truly, even for long-range offense, this ability is unmatched in versatility, and that's not even the end of it. Upon touching his opponent, he can also control their gravity, making them lighter or heavier at will. This even stacks with his original soul-based gravity powers, allowing for immense damage even if he doesn't decide to just float someone up into the air before dropping them with 10x gravity. Finally, he can control his own gravity, allowing him to move at high speeds, leap great distances, walk on walls and ceilings at will, and strike with far greater force than he could normally.
** Chain Reaction: By exerting himself more, Sans is able to control the gravity of something via chain reaction. Thus, if you are on the ground while he is too, you're not inherently safe from being controlled directly. However, the further he pushes this ability, the more it takes out of him.
* Corruption: The "full power" state of Sans' new powers, and what could be seen as their true form. It is personally activated by him saying "To thee, the granting of a gloomy corruption; may ye never awaken again", though whether it's a trigger Gaster somehow set himself or if it's merely a personal mental trigger for Sans is unknown. In this state, Sans' eyes fill in with dark red, resembling heavily bloodshot sclera, and gain black irises with tiny red pupils. Moreover, black-and-red markings cover his body, almost resembling tattoos. In this state, he can manipulate the gravitons in his surroundings, which he usually does in two very particular ways.
** Density Enhancement: Sans is able to increase his own density to amplify his physical capabilities to an incredible extent. He becomes able to punch or throw his opponents across entire rooms and streets with little difficulty, and crush steel, flesh, and bone alike with his bare hands. It's thought he could probably crush a whole tank with this, but he never got the chance to test it.
** Gravity Spheres: Sans is able to generate black-and-red balls of compressed gravity in his hands and throw them at his opponents. They can act as simply very powerful projectiles, or almost like black holes that consume everything in their path. They can also vary in size, with larger gravity orbs obviously being more powerful. He is also able to detonate these gravity spheres by firing his Gaster Blasters at them, resulting in large explosions of blue energy (not "avoidable by standing still" blue). Though such detonations occur whenever the gravity balls collide with any kind of sufficiently powerful energy attack, such as powerful fire magic or other people's Gaster Blasters, so it's more of an active application of an existing phenomenon.
== Weaknesses ==
* Loss of Control: Sans is unable to control himself when activating his Corruption state. He will merely continue assaulting everything around him until either he dies or Corruption is shut down.
* Electric Chip: The chip installed in Sans' skull will shock him with magical electricity if he remains in the Corruption state for longer than 5 minutes, putting the state on a time limit unless the chip is removed.
* Surges of Magic and Determination: A powerful enough surge of either magic or determination (though not both at once) through his body is able to destabilize the odd power in his body, forcibly cancelling out Corruption as the power restabilizes itself. This is how the chip in his skull is able to shut down Corruption, though it also leaves him with just his standard abilities for a brief moment.
* Loss of Karmic Retribution: For reasons unknown, this Sans is unable to utilize the "karma" ability displayed by other Sanses. However, this isn't much of a problem due to his other enhanced abilities.

== Trivia ==
* The Corruption version of his design was created first.
* This version of Sans was quite literally created on a whim.
* Despite his outward demeanor (sometimes) and his out-of-control nature when Corruption is active making it seem like he would be perfect for Team Void, he is actually much more likely to join Team Hope. He would likely be a rather powerful member of the Ember Division, only restricted from joining the Spear Division due to the danger posed by Corruption.
