Duality!Cyan is a unique version of Cyan!Sans, who is a Sans-type skeleton who was born from a universe known as DominionTale. He has a brother named Admiral who is a Papyrus. His father's known as Dr. Destro, who is a Gaster skeleton who is also classified as a "Shadow Walker". He's the apprentice of both Ink!Sans and Error!Sans, and as Duality, he's a fusion of his Pacifist and Genocide counterparts.

Backstory:

The origin of Duality!Cyan is the same as his past self. When Cyan was 15 years old Skeleton wise he was abducted by Humans who invaded the underground. For 6 years he went through countless painful experiments. This includes him becoming comatose due to drugs and other testing products. After finally escaping he found himself outside of the underground. Unaware that the majority of the population was either abducted or dusted. He searched for a way inside, or a way to free the others.

One day while exploring for supplies he found a rift where he had stepped into it out of curiosity. The rift closed behind him as he witnessed Error!Sans, in the middle of arguing with Ink!Sans, tear apart an AU with his strings. It triggered a fight between the two. While they fought he investigated the scraps of the universe only to realize it was his own. Ink was first to notice him and ended the fight quickly.

Later down the line, Cyan became the successor of both Ink!Sans and Error!Sans, and decide to carry out their gifts to do whatever he wants to do with them, and yet, even after all of that, he is still a very curious entity, and due to being of a neutral monster, he has not decided on what he wants to do, and what purpose he can and should have.

Cyan is unique compared to the other survivors, because unlike most of the other Sanses in the AUs, his actions and personality are determined by what type of route that he is in, and there are 2 cases for such a thing. The first case is that of the Pacifist Route. In the pacifist route, he is a pure-hearted person that refuses to kill someone, but will still fight if he is forced to do such an action, and in going through a route such as that, Cyan is able to meet Alpha!Sans, and become one of the most important protectors of the Multiverse, due to not becoming incorruptible. In the second case, there is also a Genocide Timeline, where he becomes corrupted, and when that corruption came, he worked with Error404 and Error, one of his mentors, and became one of Error404's Puppets by his own will, and became a Right-Hand Henchman.

In these 2 Cases, Cyan works with 2 of the strongest Sanses in the Multiverse, one that is if the origins of a protector, and one that is of the origin of a destroyer, as well as being the strongest Sans alive. And yet, even though they are the same person, they took different routes that effected their personality. But than, one event happened that changed the entirety of Cyan's life, or rather, the lives of the 2 versions of Cyan!Sans.

In the Multiverse in which Cyan!Sans was involved in the Pacifist Route, after training with Alpha!Sans and becoming of the most important protectors, he became a rather capable Sans that is able to protect the Multiverse, and while he is not strong, he became very skilled in his power. However, in that same Multiverse, like most of the other protector there create, Ink had done something that Cyan is unaware of until he had seen what happened. Ink, like the other versions of Ink from different Alphaverses, had taken a deal from an Unnameable, and became a host for the Unnameable itself, giving himself true emotions, but now under its influence. And when Ink came back after wreaking Havoc onto the Omega Timeline, he came to Cyan, and seeing how powerful he had became, due to training with Alpha and Ink himself, he decided to train him so that he can consume him. But Alpha became aware of this, and thus, warned Cyan of this when he and Cyan were alone. Cyan, although really scared, does so, and when Ink and Cyan are alone, Ink and Cyan became to train and spar with each other, in order to make Cyan stronger, both magically and physically. He improved on the design of the Creation Spray Paint, now giving Cyan the ability to create more than ever before, and trained his mind to act as creativity as possible and fight with his mind. They kept this going, until it reached the point in where Ink thinks that he is strong enough to make himself become more stronger than before. And so, he attempted to take Cyan by surprise, and attempted to consume him. But Cyan is ready, due to being earned by Alpha, and is able to dodge at the last second, and than began to fight against Ink for real. Thankfully, training from Alpha had been an additional help for Cyan, because if it wasn't for that, than it would not have been enough for Cyan to go against Ink. And Cyan, he had to fight against, not just someone that had been his teacher, but someone that had once been his friend, and as much as it hurts him, he still fights against him anyway.

While in the fight, Cyan tries desperately to try and reach down to the part of Ink that cared for him, tries to reason with him and to remind himself of who he is, and his goals, but Ink, now under the influence of the Unnameable, does not want to be reasoned with, and instead continues to try and consume Cyan. And needless to say, Cyan is not having the time of his life, especially since he is hurt by the fact that he had to fight someone that he had been friends with for such a very long time. He did all that he can, but he is getting overpowered, and he would have been defeated and consumed eight than and there, if Alpha had not intervened, and knocked Ink out cold with a punch, before he is able to tell Cyan to get out of here, as he will take care of it. Cyan tries to tell Alpha that he does not want to leave him be and Ink, believing that he can be saved still. But Alpha tells Cyan that it is not with the risk being near Ink in this way, and thus, tells him to leave as fast as possible, or he will never be able ti free Ink from this. Cyan is unsure of this, but he decided to leave, and due to training with Alpha, he is able to teleport to any AU that he can think, and the AU he chose to enter is Outertale. He chose to hide in this AU, due to how large it is, as well as the fact that it is a very peaceful AU, and thus, since that is a favorite to Ink, it is unlikely that he will be willing to consume it. But that is wishful thinking on Cyan's part, as he just hopes that he does not notice him.

But as Cyan is hiding in Outertale, suddenly, he sees a type of Time Portal of some kind, as Cyan looked to see why there is a Time Portal, only for the portal to suddenly suck him in, and Cyan tries to run from the portal itself. But the power of the portal is way to strong, as Cyan is than sucked into the portal.

Meanwhile, in the other Alphaverse, and one that involves the Genocide Timeline version of Cyan, he and Error are on a mission sent by Error404, due to the importance of it, but during this time, Ink had came out of nowhere and attacked Cyan and Error, and this caused the both of them to fight. Of course, due to Cyan training with Error404 and Error having given him a few more whips with differ functions, he is able to contain with Hollow!Ink and is able to hold his ground against one of his mentors. Of course, with Cyan being one hell of a jerk, he is not that much of a helpful person in the fight, and insists on doing stuff his way, and ultimately, it is this act that had almost costed him his life, as Ink has been able to overpower him without much issue, and almost got consumed by him, if it weren't for Error being able to rescue him, but this forced Ink to throw Cyan away like he is nothing more than a piece of trash.

But when Cyan is thrown away, the same portal that had taken and appeared to his Pacifist self also appeared while Cyan is in the air. When Cyan noticed the portal, and realizes that he is about to he sucked in, and lands onto something to northern himself from getting into the portal, as the pull became stronger and stronger by the passing minute. And Cyan gets hit by Ink from behind, who has began to fly over to Cyan in order to consume him, only for Cyan to fall into the portal, which closed the instant he wants inside of it.

Inside of the portal, the 2 Cyans, the one from the Pacifist Timeline and the other from the Genocide Timeline, they both began to go to each other, and when they saw each other, they are surprised to see the other, but they are unable to speak to each other, and when they got close to each other, they both began to fuse,

And it is not just the both of them that are beginning to fuse, it is also the 2 Alphatale Multiverses that are next to each other, and nobody is aware of this, nobody but the Cyan's who are in the middle of their fusion. They try to pull away from each other, but the force of the power is too great, as the 2 Cyan!Sanses merged together, and the merged Cyan!Sans, nicknamed Duality, is than taken by Anomaly!Core, who is a version of Core!Frisk. And it is here that he meets Space-TimeKid, who is the one responsible for the portals that had fused both versions of Cyan together. Cyan demands to be brought back to his Multiverse, but Anomaly!Core reveals that a neutral version of Cyan has appeared, and thus, he cannot return back. When Cyan asked why he needs to stay here in the Alpha Timeline, even though he never asked to come here, Anomaly!Core says that she has a proposal for him, with Cyan tilted his head in interest.

And about a couple of months later, Cyan had gotten used to the company of Anomaly!Core and the Alpha Timeline, even though he was distrustful and is kind of a jerk. He is one of the most important members of the Alpha Timeline, due to a deal that Anomaly!Core has given to him, although what type of deal it is, well, that is a secret that only Anomaly!Core and Duality!Cyan knows of.

Appearance:

Duality!Cyan wears a dark blue colored jacket with gold marking at the edge of the sleeves, that reaches down to his ankles, with the jacket itself having a light blue fluff hood. He wears dark-colored cuffs at the wrist, and he wears a red scarf with white plaid across it. He wears a purple colored shirt with  blue markings at the sleeves and bottom of the shirt. He also wears short black pants and a single white stripe on each of the sides. He has a White eye-light and his Cyan colored SOUL grows a couple sizes. Finally, he has a 4 on the back of his left hand. He is additionally a bit more taller, now at the height of 4'0, and is now 23 years old.

Personality:

As he is a perfect balanced form of his Genocide and Pacifist self, he has both traits of both sides, and thus, giving him some combination of both of them, but now has a distinct personality of his own. For the pacifist side of him, He only fights if forced too, but he will always spare the opponent. He accepts his past and will willingly talk about it to those curious. For the Genocide parts of his personality, he will kill without restrained, and that is only if he is forced by his hand, and he can be a jerk to others, but this is to cover up the pacifist part of his personality. And beneath the jerk attitude that he has, he is a very innocent person that does not take pleasure in the stuff that he has done, and admits that he is ashamed of himself with the stuff that he has done, but hides that remorse so that nobody can notice him in the state that he is in.

Powers:

Gaster Blaster: Like Classic!Sans, he has Gaster Blasters which he can use to shoot and attack with. Depending on which form he's in will change the look and style of his Gaster Blasters. But now that he has been fused with his Genocide and Pacifist self, Cyan's Gaster Blasters are now much more stronger than ever before.

Creation: he has a Spray Can he keeps on him, he can use this to spray a mist of colors. From it, he can grab hold of anything artificial. For example, say he needed a campfire, he could gather all the supplies from a simple cloud of colors. This can also be used to create anything he can think of, as long as it's inorganic. This tool was given to him by Ink!Sans.

Whips: Originally, Cyan only had one whip, which is made of Error's Blue Cables. But since coming back, he is now given a few more whips to Cyan, in order to make him even more harder to defeat.

Destruction: He has a whip created by Error's Blue Wires. With it, he can lash at enemies, or reach hard to reach places. For example, he could use it as distant combat or could use it to knock something down to catch. This tool does 20-30 damage depending on how accurately he hits you with it. This was given to him by Error!Sans.

Torment: Another Whip that Cyan has gotten, created by Error's Red Wires, this type of whip allows him to attack and give off a feeling of burning hot lead around the body part that the Whips is wrapped around.

Treatment: A Green Whip that Cyan has gotten from Error's Green Strings, he can wrap this around a person and use the whip to heal others that the whip has wrapped around.

Hallucination: Made from Error's Black Whips, Cyan can wrap this around a person in order to disorientate a person's senses in order to make them hallucinate something that Cyan wants them to see.

Bone Manipulation: can use bones to attack with, these also deal 1 damage each +poison damage. The damage increased due to training with Error404 and Alpha, and the fusing of the 2 Cyan Sanses made the bones more stronger than ever before.

Trained Blue attack: Cyan can use blue bones and gravity attacks, and since training with Error404, he can utilize blue magic in order to push something as large as an island out of the ocean. Fusing made the Blue Magic more powerful than ever before.

Patience: Cyan will feel exhaustion from battle and has high stamina. He won't ever get "tired" because of his soul trait.

Time Crawler; Cyan, due to training on with his soul trait, is able to make time slow down to the point where it almost looks like it has stopped, but not really. Only entities like Error404 and Righteous!Error, or anyone comparable to those 2, are able to resist this effect. However, beings such as TimeKid can also resist this effect, due to the fact that he can manipulate Time himself.

Ropes of Patience: Training with his Soul Trait has a allowed Duality!Cyan to produce sticky ropes from his fingertips or the palms of his hand, and through doing this, Cyan can grab his opponents and trap them by tying them in ropes. They cannot be detached unless Cyan decides to let go or the rope is cut off. Cyan can also use the ropes as a deadly weapon by pulling on the rope. This will result in the area attached by the ropes to be violently ripped out.

Blackout: When he enters what's known as a "blackout stage" his blasters gain their personality and come to "life".

Nimble: Having quick reactions and great flexibility, he can evade the majority of enemy attacks or strikes. He can also move acrobatically and out-maneuver his opponents.

Shadow Walker: He is given the ability to evade some attacks and moves are still affected by blue attacks and some colored attacks. He will become a shadow and his speed becomes increased. A small time frame before and after, he will be able to levitate

Mind Target: Training with Error404 has allowed Cyan to attack a person's mind by giving them a headache, and can control the severity of it, either by making it extremely painful to the point that they become unconscious, or to the point that they are disorientated and confused.

Mind Wipe: Training with Alpha, Cyan gained the ability to erase and distort the memory of any person in front of him, making them forget that Cyan existed.

AU Teleportation: Cyan has now grown powerful and skilled enough to teleport to an AU that he chooses to go to.

Enhanced Physicality: Duality!Cyan has trained his body to the point where he is immensely strong and fast. He can run so fast that he looks like he is teleporting, and he can punch with enough force to make a human explode.

Beginner God Ray: Training with Error404 allowed Cyan to make a God Ray of his own, although this one is weaker even when compared to Righteous!Error's Glitch Ray. Cyan, with his own God Ray, can fire a blast from his fingers that will kill anything and anyone who has code. Those that are attacked and struck by their Ray are either paralyzed and unable to move for an entire few minutes, or are killed by having their souls degraded by the power of the Ray itself.

Double Eye: Cyan, through his training with Alpha, has been a blessing to learn and make 2 hate eyes of Gaster and this power dramatically increases his power, giving him immense power of magical impulse. These eyes also increases his physicality much more than ever, allowing him to become a much more difficult opponent to try and struggle against.

Flight: Cyan is capable of flight, but unlike Hollow!Ink's flight, he can turn into shadowy smoke which allows him to fly, and in this phase, he cannot he touched until he lands back onto the ground, and is unable to stop while in midair.

Relationships:

Ink and Error: both Protector and Destroyer of AUs, they are the ones that Cyan became a successor to, and Cyan ended up having a bad relationship with Ink in both Alphatale Multiverses, and onky have a slightly close relationship with Error in the genocide version of Cyan!Sans.

Error404 and Alpha: 2 of the strongest Sanses in the Multiverse, Error404, in the genocide run, is the boss of Cyan!Sans, although he has helped him in his powers, due to being Error's successor. Meanwhile, in the Pacifist Timeline, Alpha became his mentor, due to being Ink's mentor, and is able to help with his magic and his physicality. But as fused Cyan, he does not seem to care for the both of them, but does recognize them to an extent, however, this is due to his lack of self-identity, as he is now a fusion of pacifist and genocide.

Space-TimeKid!Sans: A Version of TimeKid Sans, he is the one responsible for the creation of Duality, due to wanting to experiment on his powers to see if he can travel from one multiversal timeline to another. But Cyan unintentionally went in, which is not how it was supposed to go.

Anomaly!Core: Anomaly!Core, the owner of the Alpha Timeline, meets Duality!Cyan, after Space-TimeKid accidentally created him. Duality!Cyan, due to being able to remember what he had gotten through with humans, is initially distrustful and even is admittedly hateful to Anomaly!Core, due to his experience with being experimented by humans at such a young age. But due to Anomaly!Core making painstaking effort to gain his trust and a deal that she has made with Duality!Cyan, Cyan grew to trust her to the point of becoming one of her most loyal allies and followers.

Sans (Underswap): A version of Sans that has swapped places with classic Papyrus, with Sans being the brother of puzzles, while Papyrus is the lazy brother. When Duality!Cyan first met him, Cyan is reminded of his pacifist self's memories, and thus, he struck a good friendship with Underswap Sans.

Stellar!Astral Mother: Although he has never met Astral Mother, he has heard of her from Error404 and Alpha, and both talked about their experiences with her, with Error404 and Alpha
