**Celerity!Sans** is a Sans belonging to Xénotale, but that has the specificity of not appearing in the main story.

## Story

### Xénotale: Celerity

Sans quietly lived in the eidocide timeline number 2 under the orders of his brother (Papyrus), but one day in this timeline, when Frisk arrived, she wanted to do an eidocide route and when she killed Papyrus, Sans began to want to train.

At first, he trained alone but as in each eidocide timeline that got to this point, Zeno arrived to train him. Zeno decided of a training strategy different than that of Sans, but more effective as well, while giving him a temporal veil, making him immune to timeline changes. In the end, Zeno then gave Sans the sum of the EXP of all the entities of the entire Multiverse, which would constantly update because of the magic.

The fight between Sans and Frisk started in the eidocide timeline number 6. When the eidocide fight reached its second phase, Sans started to have the energy. In the end, Sans beat Frisk and thanks to the energy he got, he got a colossal incrase in power. The timeline was almost empty (only Xéno!Asgore and Xéno!Flowey alive), but his power, as well as his EXP or LOVE continued to increase.

After having beaten Frisk, Sans waited in the judgement hall, until the one moment he accidentally created a travel type spatio-temporal rift. He entered in it, finding himself in the Multiversal Void. While flotting in it, he found anti-void, in which happened the Multiversal Sans tournament. He participated in it. In the finale, he faced an extremely powerful opponent called Alpha!Sans. He had to give all his abilities and all his speed for the first time. Everyone then discovered that his speed was the celerity. They were starting to call him Celerity!Sans.

After the tournament, Zeno called him and brought him back in his AU. Zeno proposed him to enter in his organization, a proposal that Celerity accepted. Soon enough, he did his first mission, which was to kill the Asgore and the Flowey of his own timeline. He did it, then Zeno brought him in the headquarters of the organization. Not long after his first discovery of the headquarters, Zeno left to create his soul of celerity. Zeno removed his old soul in order to replace it with this new one.

Just after, Zeno made him test his new abilities in a blank universes, and made him discover what these universes were. During the test, Celerity destroyed the blank universe 832658, which called the attention of the protectors. After the short test, Zeno gave him free time. During the free time, he met Alpha!Sans again. He revealed to Alpha that he was the one to destroy blank universe 832658. Alpha presented him to the protectors, which he also confirmed to that he was the cause of the destruction of the blank universe 832658. If Ink!Sans wanted to add him to the list of potential threats to the Multiverse, Alpha!Sans preferred to test him to see if he could become a protector. He entered in Undertale for the first time during this test. He met Error!Sans for the first time there. He teleported Error!Sans in the Multiversal Void then continued his formation.

Back in the Multiversal Void, he met Infected!Sans, which he has beaten very quickly. He entered in Outertale, where he met Opposite!Sans. However, Opposite left him quickly. When Opposite came back, it was only to reveal to him that Infected was attacking Outertale, an event Celerity wanted to stop. Celerity fought Infected a second time and beat him again, though the fight was more difficult this time. After the fight, he came back to the Doodle Sphere to see the protectors. He ended up becoming one of their allies, not being authorized to become one of them.

After that, he was called by Zeno for a new mission. The mission was to destroy Dusttale. He got a summary of what the mission was about, got to Dusttale and met Great!Sans there. Celerity decided to help him in his training. After helping Great!Sans in his training, Celerity destroyed Dusttale. After this mission, he got free time again, which he wanted to use to discover more about other universes. He got in an AU called Corrupted Justice, where he met CJ!Sans. He became friends with him, then CJ!Sans wanted to make an EXP absorber for Celerity and the protectors, though he needed time to make it. In reaction to it, Celerity went in another timeline, where he met Trevor Kingsman after making humans panicked without wanting it. However, Trevor was a liar who wanted to use him to make money for himself. Celerity discovered it quickly, killed Trevor, and took his soul. He took CJ!Sans's EXP absorber, then returned to Zeno's HQ, where he gave the deceit soul to him. After a little discussion on soular heterochromia, he went in the Doodle Sphere to give the EXP absorber to the protectors.

A bit of time after, he decided to change his appearance, more precisely his clothing. To do so, Zeno recommanded to him to go see Innovation!Sans. Following Zeno's recommandations, Celerity went in the new idea, where he met Innovation!Sans and Démolition!Sans. Innovation!Sans accepted to make him new clothes, and while waiting for them, he discussed with Démolition!Sans. Both got along well with each-other. When Innovation!Sans had finished his new clothing, he met back with Zeno then with Alpha!Sans to show them his new clothes.

When he met back with Alpha!Sans, he got an authorization from Zeno to tell him some truths. Even after these truths, Alpha still decided to help him train. After the training, him, Alpha and a bunch of other persons got an invitation to go to an Outertale meeting. He went to it, bringing Innovation!Sans and Démolition!Sans along with him. During the meeting, the subjets discussed about were the destruction of Dusttale and Corrupted Justice going from coded to codeless. Forced to make sure that nobody discovers that he is related to these two events, he made sure that Great!Sans forgot his passage in Dusttale thanks to Alpha!Sans's help, and to not give out any information on the matter, along with telling CJ!Sans to not talk about the deceit soul. The Outertale meeting finished on a doubt, and he left it with Alpha!Sans. After making sure they were alone together, Celerity told Alpha about thz organization, about Xénotale and about his story to Alpha. Alpha could not see Celerity as a bad person, and invited in the Doodle Sphere to see the protectors' archives. He then entered Zeno's HQ to sleep.

Celerity woke up, then ate with Zeno in the headquarters, while having a discussion with him. He discovered more about Zeno's AU and Zeno himself during this discussion. After it, however, Zeno gave him a new mission, which was to observe the consequences of The Voice's apparition in the Multiverse. The first victim of The Voice he saw was Opposite!Sans, to which he asked questions about The Voice to discover more. After having left Opposite, Celerity went to the Doodle Sphere to speak about it to the protectors directly, where he observed Syno!Sans as a victim of The Voice. The protectors wanted to know more about it, and even if they got informations, Syno!Sans wanted to leave them. Celerity joined Blueberror's side and decided to let him leave. Ink had a plan to get more information about The Voice, but Celerity got called by King Multiverse!Sans. King Multiverse and him fought in King Multiverse's anti-void. King Multiverse just wanted to slow him down for Error404!Sans. Celerity won the fight and came back to Zeno's HQ. There, Zeno ordered him to tell a message to Error404!Sans, which Celerity did. Celerity and Error404 discussed a bit after that.

After having told this message, Celerity got a new mission instantaneously. To complete his mission, Celerity went in the Doodle Sphere, more precisely in the protectors' archive to steal the Arttale folder and bring it in Zeno's HQ. He then went to see if The Voice was as active in the Multiverse as just before. He met Alpha!Sans again, then told him about his relationship with The Voice. Alpha asked him what he was doing for the organization, and then, Celerity thought that he was only doing bad things for the organization. Zeno called Celerity to destroy an AU, which was too much for Celerity. He decided to fight Zeno in the Void of his timeline, but Zeno won the fight easily. Zeno teleported him in Infinitetale to explain him some things, and both got to be getting along well, Celerity still working for Zeno's organization. After having left Infinitetale, Zeno came to see to the protectors to tell them about Infinitetale, an AU they had never discovered.

### Xéno!Papyrus's journey

He appears for the first time with Alpha!Sans, but they are quickly spotted by Error!Sans. Both erase his memories and make him return in the anti-void 6. Some moments later, he comes to Papyrus for Zeno. He tells him about the blank universes and makes a proposal for him. When Papyrus has passed the trial, he presents Zeno to Papyrus. Later, he returns with Alpha!Sans. After Papyrus success at his mission, he talked with Zeno about the organization then return with Alpha!Sans to help inhabitants from many AUs.

### Xéno!Frisk's arrival

Though it is not revealed when it happens, he is one of the two voices that help Xéno!Frisk to survive to her fight against Error!Sans. Later, Xéno!Frisk meets him. The protectors gave him the mission to accompany her in her discovery of the Multiverse. Xéno!Frisk discovered about him quickly, which make him explain the Multiverse to Xéno!Frisk after having brought her in an anti-void. He completed a mission of analyze of a speciat trait of anti-void for Zeno. Not long after, he brought Xéno!Frisk to the headquarts of Zeno's organization. Zeno and himself explained many things about the organization to her. After Xéno!Frisk's joining of Zeno's organization, he observed her doing her first mission.

Some time after, he met with the protectors to lie to them about Xéno!Frisk, making them believe that she left by herself alone. Soon later, he explained to Xéno!Frisk what her test of competences would be, before using a spatio-temporal rift to teleport her to Underfell.

He created the spatio-temporal rift that brought Xéno!Frisk to the place of her spying mission, and the one that saved her soon after. With the other members of the organization, he went to the reunion and information room of the headquartes to get informations about Aether and Erebus. He then got sent in a mission to fight them, though it mostly was to get information about their way of fighting. He fought them as well as Opposite before leaving the fight. He decided to read the Arttale folder after this mission.

### Undertale Psi

Celerity fights Infected in the Multiversal Void, winning the fight. He is called by Zeno for a meeting of the organization, bringing Alpha!Sans with him. Celerity participates to the meeting, then goes to investigate about the Arttale folder. After some thinking, he finds the person who has destroyed Arttale, Error404!Sans, telling him the story about the destruction. He stops for a while to protect the archives of the protectors for the protectors. There, he meets Ink!Alphys. They have a discussion about Ink's ways to treat other Out!Codes. Celerity then gives Ink!ALphys the folder of the Eye. He guards the archives of the protectors until Alpha!Sans arrives, and then he gets called for a meeting, though he spent time in the Mainframe to save Error!Sans and his allies for Error404. During the meeting, Zeno gives him the mission to defeat the cult of Chaos with Xéno!Papyrus and Xéno!Frisk's help, learning just after that Alpha and Error404 are brothers. During the mission, he fights Aether, Erebus and Opposite. After the fight, he is called by Ink!Sans. Ink!Sans, Alpha!Sans and himself have a discussion, in which he discovers that Ink!Sans has partially discovered Zeno's organization and tells Alpha!Sans Ink!Sans's past.

After Ink!Sans's departure, he decides to give the news to a few friends. He first goes to Error404, then goes to find Ink!Alphys, after having learnt from Zeno that she is in Corrrupted Justice. He finds her and informs her on the truth about Ink!Sans, before he follows her in her research. He meets CJ!Undyne and interrogates her with Ink!Alphys, then they both fight CJ!Undyne before he is told the existence of the Showmaster. After this discovery, he and Ink!Alphys try to attract the Showmaster via a beautiful fight thanks to CJ!Papyrus's help. The first attempt was a failure, and they could only find the Showmaster during the last fight between the inhabitants of the AU. After CJ!Chara's victory, he shows himself to stop the Showmaster, but Ink!Alphys's intervention prevents him from doing much. He watches Ink!Alphys's fights until he has to save her from Skell at the last second. After the failure in Corrupted Justice, Ink!Alphys invits him in the laboratory, which makes him discover a lot about the anti-void. He then returns in the Doodle Sphere to discover that he became an official protector of the AUs. He then goes to investigate about Skell with the help of his protector colleagues, and Error404's. He learns more about him thanks to Error404, and then decides to go to sleep.

He goes to eat and talks to Zeno as he wakes up, most notably talking about Error404's favorite question, and food. He then returns to the Doodle Sphere for his mission for the protectors. After having filled out the folder he was associated with, he goes in many AUs to help their inhabitants, accompanied by Alpha!Sans. A long moment later, he gets contacted by Zeno while he is in Outertale with Alpha. Zeno asks him to go to the Multiversal Void and take Xéno!Papyrus back to the headquarters. Celerity brings him back to the headquarters. He then receives and summary of the situation. He then goes to the protectors to receive an invitation for an Outertale meeting, and is then given the mission to give the other invitations. He succeeds, then prepares himself with Xéno!Papyrus and Xéno!Frisk so nobody could guess that he knows them well. He is present during the whole Outertale meeting, as he reveals the recent information about Ink!Sans, and listens to all past informations regarding Multiversal Web!Muffet. After the end of the meeting, he teleports himself back to the headquarters.

Later the same day, he is the Outertale Grillby's with Alpha!Sans, having a discussion with him and P4142!Grillby. He eats a bit with Alpha!Sans before he goes to look at the stars with him. After having spent a long time looking at the stars, he returns to the headquarters, meeting Zeno first. Zeno proposes to him to visit Soulstale, which he accepts. They first go in the space of the AU, seeing the remnants of a murder. After an analysis of the scene, they go to Kastel-Souls, looking at the view on there. Eventually being noticed by Nashi Masuku and Souls, they enter in the kastel with Souls's permission, sitting around a table to have a long discussion, before Celerity accepts to fight Souls. He takes ownership of the Arena before fighting Souls. He prepares the fight with Souls by telling him all of the properties of the Arena, then they fight. The fight ends with Celerity's victory, and then him and Zeno leave. They quickly come back to the headquarters, and then he leaves to inform Error404 about King Multiverse's betrayal and death. In the Mainframe, they both agree that Error!Sans should join Celerity. Before Error404 tells Error!Sans, Celerity fights Error666, the fusion of Error404 and Error!Sans, and wins. He then adds Error!Sans to what he makes him believe to be his own organization separate from the protectors.

One day later, he talks with Error!Sans as the latter is in his bedroom. Celerity returns to the Doodle Sphere to read some folders after the discussion, but first meets with Blueberror. After having discussed with Blueberror, he joins Timekid!Sans and reads folders with him while talking with him. As he reads the folders of the archive even after Timekid!Sans has left, Alpha!Sans tells him that the studients will come in the Doodle Sphere. He then rejoins the other protectors. As the Doodle Sphere is being invaded by the Infected cult, he surprises Infected by his presence, then fights Infected and Dunamiz at the same time. After the end of the fight, he spares Purity and Dunamiz and demands them to leave the Doodle Sphere with Infected's statue. He and the protectors then get visited by Opposite!Sans, Artist!Sans and Reaper!Sans, giving them news on the Infected cult and Pandora!Ink.

After having looked for informations about the latest events for two hours, he returns to Zeno's headquarters to organize his bedroom and read. His reading time gets cut short as he gets challenged by NewLie. He accepts the challenge, deciding to fight her in the Arena after a discussion. He wins the fight, and then the two continue to talk together for an hour. He then takes NewLie to the Mainframe to report the results to the fight to Error404, then talks with him about NewLie's promotion. After the end of the discussion, he comes back to the protectors, and is told about an Out!Code named G. He makes sure to find an excuse to visit Opposite!Sans, then asks him information about G's order. He goes to spy G when he is told the wanted information by Opposite.

## Appearance

Celerity is a skeleton that has a height of 5'3" and a weight of 12,8 lbs, of course looking like a Sans. He wears black slippers, black shorts with white strips. However, one of his most noticeable aesthetic parts about him in the first place is his light gray jacket with a black hood, with blue and orange specks in multiple places on the jacket, this jacket being given by Innovation!Sans. Another aesthetic noticeable part is his skull. The irises of both his eyes are different. The iris of the left one is polychromatic, where the one of his right eye is simply yellow. He also has a crack in the left part of his skull, both of the cases on his skull being caused by the first time he passed through one of his own spatio-temporal rifts.

Before metting Innovation!Sans, he had the same clothing as Xéno!Sans.

## Personality

Celerity!Sans is first described as a "good person", which is caused by his desires to do good around him, while hating to make other people suffer, unless they have deserved it. For him, people that have deserved it usually are tyrants, organizers of mass murders or even destroyers of AUs, and sometimes the big liars, most notably the ones whose lies have harmful consequences. However, he kills and destroys AUs by himself multiple times, which he quickly ends up regretting, yet he knows that he does not have the choice to do it some times and accepts it, though it haunts him sometimes, yet he doesn't let that lower his efficiency. However, he considers that he failed if he doesn't succeed in saving an AU or a timeline, giving him regrets when it happens.

He is not the kind of person to automatically decide to punish a person for the actions that he judges reprehensible, since sometimes, it just is the way of being of an AU, and he prefers to respect it. He also knows that there is a possibility that the person improves later on, even if he considers it unlikely. He also cares a little about himself, so he is not confused with another Sans. He also stays friendly towards certain persons, often having calm discussions with them, in which he likes to make puns from time to time, but he doesn't like to show his discomfort. He knows that it can not happen most of the time though, which is a thing he hates. Sometimes, during his calm discussions, his curiosity makes him ask personal informations about a person, and his curiosity can most notably be seen when he discovers a new AU. He himself doesn't know a lot about many AUs and Out!Codes. What shocked him the most when he discovered the Multverse is that most of the notable persons he can meet in it are other variations of himself, though he eventually got used to it. His gathering of informations can be more complicated, and in this case, he just uses his past knowledge to make theories. He also likes to be followed during his research. When he goes on to discover AU, he has no particular AU he targets, and thus walks in the Multiversal Void to enter in a random AU, without knowing which one it is beforehand. If he wants to go in a specific place however, he teleports himself to it. While being curious, he keeps many secrets about Zeno's organization and about the Multiverse itself, to Out!Codes and non-Out!Codes. The few exceptions are the people that are planned to become members of the organization, or the few persons that are authorized by Zeno himself. He can understand that people are shocked to learn about its existence. He also keep secrets about Error404's organization or about Alpha!Sans, and believes that the information he must know are those that are relevant to Zeno's organization. Depending on the specific discussion, he does alternate between making sure that the subject is never brought up and saying that he will not reveal anything about it. He also does not easily fall for traps made to get him to reveal secrets. Though he sees the reason to do it, he hates keeping secrets, and hates lying. It is notable that lying gives him a state of regret almost as strong as killing people that did not deserve it, even if he often lies to the protectors. He stays kind with most of them. He also likes to be lazy from time to time, even if it stays uncommon.

He is more often that not loyal to his friends, not hesitating to give them recent informations about the Multiverse, and will often first meet with friends or acquaintances. He also likes to relax with them, sometimes by eating and sometimes by doing nothing. He would prefer to be capable to tell everything about Zeno's organization to his closest friends, but knows that he must do everything to hide it, and thinks that it is better to do so to keep them safe. Sometimes, when he has informations to give to his friends, he has to report the discussion to a later moment, but makes sure to get back to it as fast as possible.

However, when it comes to people he dislikes, he sometimes likes to prank them. He often chooses the method that is a balance of a fun and an optimal method when doing so, as long as he knows a lot about the concerned person.

Though he does not like to kill innocents and to sacrifice people for no reason, he does not have anything against the idea of fighting itself, and even likes to do it occasionally, though he prefers to make sure that his opponent does not die definitely unless it is useful. He can be excited on the idea of fighting someone, especially if the person makes him curious about them, or even when the capabilities of the person make him curious. Sometimes, when people do give him a good reason to not fight, he does not do it. A bit more rarely, he can even be the person that tries to stop the fight. He also doesn't hesitate to train himself. He prefers to do it with a partner, often Alpha!Sans if possible, but if he is without a partner, he prefers to do it in a blank universe, not only to reduce risks but also because of his hate of blank universes, which he considers pointless at the scale of the Multiverse. In fact, he even goes to the point of destroying blank universes just to let their place to AUs that could generate afterwards.

He also likes fries and ketchup a lot, and in the second case, prefers to drink it directly in bottles, as he missed it back at the time he wasn't an Out!Code. He does not have a liking for chocolate, and hates the Papyruses' cuisine. He also likes to look at beautiful sceneries, such as the ones of Outertale. He cares a lot about his jacket, as it gives him a noticeable way to differenciate him with other Sanses of the Multiverse, but does not care about the rest of his clothing. He also likes to read a lot, and would like to read more. His favorite books tend to be physics books, as he is a passionate of physics in general, and can even not notice people when he reads. He has a great liking of people that have a sense of honor and duty. He is rarely formal, and even most of the time, it is the opposite, as he speaks to every person he meets with as if they were a person he would meet in a random universe. He can sometimes give long explanations, but makes sure to do it only when people are interested in getting them, and avoids explanations on elements that could bore the persons he talks with from time to time. His biggest dream used to be to become an official protector of the AUs, though he was coming to them very often to find a way to spend time, even if he considers their beliefs to be stuck in the past, though he believes this because he also believes that they are this way beause the protectors have been badly influenced. That was making him do missions for them in these cases. However, he knows that if there is too much protection and not enough destruction, the Multiverse can collapse on itself. Though he hates the fact that this is true, he is capable of bearing it, most notably by making compromises. It is why he fights and causes destructions, either directly or indirectly, mostly destructions of blank universes when it is directly. He has a big fear of becoming useless.

Though he is the second in command in Zeno's organization, what he sees in it often makes him sad. He finds what happens in it uninteresting, and has a desire that its situations gets better. He prefers to go in his bedroom when the main room is occupied since the situation makes him sad. He also feels bad when the other members of the organiation show that they hate him, even though he is used to it and can bear it.

Though he often visits AUs, going into the Snowdin forests of the AUs does not interest him due to what it is like in his origin AU. He also lacks a feeling about Hotland, though prefers this place to Snowdin.

As a protector, he does not hesitate to share information about recent events to his colleagues. However, during the meetings, since he has way to get informations that must stay a secret for the protectors, he makes so he can find a random excuse to get them while staying credible. He also is serious in his work, even if he reports the writing of the information inside the folders to later moments a lot, as he considers this to be the boring part of the work of a protector. He often tries to do his work as quickly as possible so he can spend his time with his friends, though he still tries to do his work properly. Sometimes he decides not to go to his protector work immeditaely to spend time in his home, as long as the protectors do not notice it. He also uses his job to get to read the informations of the archives of the protectors out of curiosity. His favorite folders are those about finished cases that will never affect him and destroyed AUs, since he prefers to discover the rest by himself. He loves to place an illusion in the archives of the protectors when he protects them to prevent any attempt of stealing the folders in it.

When in a fight, he is very sure of himself, yet is careful against opponents he doesn't know. He prefers to end a fight very quickly if possible, and his way to finish depends entirely of how much he knows his opponent, though he mostly uses his Blasters. His self-confidence makes him tease his opponents, though he does never exaggerate enough for it to be mean for no reason, and often does it by touching an opponent just after he dodged an attack. He hates to kill people in a sadistic way, hating to use them even on his worst enemies, but he likes to test new fighting techniques. If an attack can continuously direct itself to him, he prefers to just take it and count on his regeneration. Depending on the situations, he does not hesitate to make up plans or simply to let time pass, but often uses Zeno's plans when he gives him one. He dislikes the idea of doing collateral damage during his fight, whether it be on people or on objects that are important to these people, which is why he most often fights in blank universes or in the Multiversal Void. When his opponents cares a lot about an object and that he himself likes the person, he even goes as far as protecting the object when they fight. When his role is one of support, he just dodges, alters the souls of the people, manipualtes gravity and teleports his allies away when they are in danger. Even if he were to just be a watcher and not a support helper, he would still save his allies at the last time, and admirates the fight anyway. When he fights in the Arena, he most often does so with his friends, or to get informations about the capabilities of some persons. However, he also shows a lot of his abilities when he fights in there, not caring as much as usual about which one he uses since people can resurrect inside it. He always explain the properties of the Arena the first time he fights someone inside it. He has nothing against letting the fights be long inside it, but stops them when continuing is pointless, or when his friends want to.

Celerity, mostly because he holds him in high regard, has a tendancy to imitate some of Zeno's habits from time to time.

Celerity likes Alpha a lot, to the point where his compliments give him discomfort, and he sometimes finds him cute. Alpha likes Celerity to a point where arguing that he may spend time with him is a good way to convince him to do things.

### Ink!Sans

*Main article: Ink!Sans*

Ink is a protector, and as such, is one of Celerity's allies. However, the two hate each-other. Ink hates Celerity because he is way too curious and active according to his standards and because he is a potential threat, and Celerity is very mistrusting towards Ink. Ink hates Celerity to the point of adding him in the potential threats list and to prevent him to become an official protector, even if he proved himself. Ink would have make him spied if Alpha!Sans weren't in good terms with them both. Ink is very curious about Celerity's origins. Celerity asks himself questions about Ink's way to act, that he finds illogic and intentional, and as such suspicious.

Later on, after an investigation, he discovers Ink's true intentions, developing a great hate for him, though he gives him a second chance since he thinks he is capable of thinking rationally. They often are rude to each-other. Celerity believes that Ink's merits are a bad influence in a lot of cases.

### Error404!Sans

*Main article: Error404!Sans*

Error404 and Celerity are allies via Zeno's organization, and persons that get along well. Since they are both good friends, they often help each-other, and have respect for each-other.

Depending on the moments, Celerity decides not to surprise him, but he still does it when Celerity is eager or when 404 wants their meeting to be quick. 404 is the first reason Celerity tolerates 404's organization since he doesn't want to do anything bad in the end, though NewLie eventually becomes one later on.

### NewLie

*Main article: NewLie*

Before they first meet, Alpha made Celerity curious about NewLie's challenge. As soon as they meet, they get along very well. They have similar opinions, but different ways to attain their respective goals, as well as a common objective that is similar but not identical. They support each-other when they talk and trust each-other. NewLie trusts Celerity enough to talk about how she feels, and Celerity has a desire to reveal secret informations to NewLie. NewLie likes that Celerity accompanies her sometimes, and Celerity likes NewLie's presence. They enjoy talking with each-other a lot.

### King Multiverse!Sans

*Main article: King Multiverse!Sans*

Celerity is often respectful towards King Multiverse, most notably by not calling him King, though they got a bad first impression of each-other.

### Error!Sans

*Main article: Error!Sans*

Error is one of Error404's minions, and as such, one of Celerity's allies. However, he is not aware of it, and is often stopped by Celerity when he tries to destroy an AU, which annoys him a lot. Celerity also likes to have fun with Error's phobia, which makes him rage more. His meetings with Celerity cause him to have a loss of memories sometimes, even if he isn't aware of it. He hates his memories loss.

Since Error!Sans is one of Error404's minions, he still does not hesitate to help him, though he mostly does it for 404. Error avoids to attack Celerity a bit because of that, though it mostly is because he stands no chance.

Now Error!Sans works for him without knowing Zeno's existence, which Celerity accepted to help 404, and because he thinks that 404 is right.

## Abilities

### Untouchable air

Thanks to the energy, he got a propriety that makes that he can't touch air as long as he does not touch a solid or a liquid.

### Kick

It is one of his main ways of fighting. Thanks to his high speed, he can charge on his opponents incredibly fast and kick them with great force. He also generates shock waves when he does it. Though he can use other parts of his body, he prefers to kick.

### Bones

He can summon very fast (celerity) bones, which can be normal, blue, orange or green. Those bones are notably used because they can generate shock waves thanks to their high speed, though they also can simply make a hole in the body of the opponent. It is possible to defend from his bones with an extremely powerful magic shield.

### Gaster Blasters

He can summon weapons known as Gaster Blasters. However, the firing speed of those is the celerity, like most of his attacks. The beams of those Gaster Blasters do damage depending of his attack against opponents with stats, but they also annihilate all matter and energy they enter in contact with, which is notably useful against codeless opponents. Moreso, he can use them in normal, blue, orange and green. It is possible to defend from his bones with an extremely powerful magic shield, as long as it is not made of matter or energy.

### Karmic Retribution

Depending on the opponent's LOVE, his attacks do karma damage that last for some time. Damage dealt to the opponent thanks to it also depend of the LOVE of the opponent. He rarely uses it.

### Teleportation

He can simply teleport instead of using his speed. He can also teleport other people with him, which is his main way to use teleportation. In the case of normal teleportation, he can't go from a place of the Multiverse to another. However, he can move in an entire universe.

### Omega Blasters

An extremely powerful variation of the Gaster Blasters. Their firing speed is the same as the normal Gaster Blasters. He possesses them in normal, orange, green, and blue. This type of Blaster can shoot everywhere in an AU, in all of the timelines of the AU (assuming the AU has multiple timelines) using a big beam that not only does infinite damage, but can also annihilate all of the matter and energy of one universe. A blue one will only do that effect to things that move and the opposite for the orange. The green one, however, can regenerate an AU that is going to be destroyed as well as all of its inhabitants.

### DNA Blasters

Normal Gaster Blasters that have a different shape and that permits DNA Control. He also can change the shape of the beams of his Blasters, but prefers to not do it or to shape them like a molecule of DNA. He can use them in normal, blue, orange or green as well.

#### DNA Control

If a person is hit by a DNA Blaster, a DNA is encoded inside them. Celerity!Sans can then make this DNA necessary for the person to live and erase the DNA from inside the being. This automatically kills the being regardless of its stats, even if it doesn't have them, as long as he manages to hit it with DNA Blasters.

### Blue soul

Can turn the soul of anyone into a blue soul, as long as this person does have a soul. This soul makes the moves of his opponent limited and prevents flying.

### Gravity manipulation

He can manipulate gravity, allowing him to do a bunch of things. He can use his gravity manipulation on himself and on others to make them fly, though he doesn't do that on himself since it's useless. He can also simply use this ability to fight his opponents, by making them move as he wants to, by sending them crash on walls, by using it in a way so strong that the the body of the victim flattens or breaks, or even simply to do damage to coded opponents, though it is not that useful against them. If a person has a big body, he can also separate the parts of their body. This ability being separate from the blue soul alteration, he can use it on soulless persons or objects, capable of having very big effects on these objects, like buildings. He can even use it on planets, or even stars. He can also use it to send what is around him to send anything that is around him on his opponents.

#### Black holes

His gravity manipulation ability is so powerful thet he can form black holes with it, though he needs to make efforts to do it, this taking four seconds of concentration to be done. He can destroy the back holes he created (only his) by a mere thought.

### Regeneration

Since he has the sump of all EXP in the Multiverse, that it is updated constantly, and since in his AU, the inhabitants regenerate each time their LOVE goes up, he gets back all of his HP when his LOVE goes up as well. However, the increase of his LOVE is so fast that he constantly regenerates. However, if a universe is destroyed, his LOVE goes down, his statistics going down as well.

### Soul of celerity

*Main article: Soul of celerity*

He can turn the soul of a person into the soul of celerity for 10 seconds. In this case, the speed of the victim will inevitably be the celerity and can only stop with a very robust object. The person can not affect their own soul in this state, and more often that not, can not control their speed. When the soul of the victim becomes normal again, it can't become a soul of celerity again for one hour. Also, since Celerity's soul of celerity is a part of Zeno himself, this soul can't be affected in any way, shape or form. Basically, it makes him immune to any soul-based ability.

### DT Extraction

This allows him to remove the determination of any being for 40 seconds. If the being is killed at that moment, they can never come back. It can only affect beings with determination, and they are immune to this process being used again on them for 6 minutes and 40 seconds after getting back their determination.

### Illusions

Thanks to the training he made with Alpha!Sans, he can cast illusions and affect the senses of his opponents. He can also "give a life" to his visual illusions, or even make someone hear sounds that do not exist for examples. He can also remove the sensations or just replace those in precise way. He also can use these illusions as an alternative way to make himself invisible, or invisible to specific persons.

He showed himself to be incapable of being affected by illusions.

#### My world

A technique of his illusions. Celerity erases all external perception transmitted of a person, replacing each and every input with what he wants his target to sense.

### Flight

He is able to float in the air and thus dodge attacks easier. He controls his flight very well regardless of his speed.

### Photomorphosis

Celerity!Sans is able to turn into a photon, though he keeps his senses and thoughts. This makes him a bit slower unless he is in an empty area, but it makes him invisible and extremely complicated to reach. However, he can only move straight.

### Statistics annulation

Celerity is able to automatically undo the abilities and properties that can affect his stats or simply based on his own statistics, EXP, EBM and LOVE included. The natural increase of stats is not affected by this sub-property of Celerity.

This was given by Zeno to avoid to destroy the Multiverse by excess of EXP.

### Temporal immunity

Because of his celerity, when the speed of the flow of time is modified, he cannot undergo the effects of any adverse attack. He is therefore completely invincible when time is modified. Moreso, he is immune to any time-based ability as well.

#### Time stop

He can stop time for several minutes at maximum. As soon as these minutes are over or as he decides to stop the time stop, he can't use this ability for four times the time he used this ability.

#### Time acceleration

Allows him to more or less accelerate the time in a precise way, sometimes only affecting the time of specific persons. He can also do it generally.

#### Time slowdown

Allows him to more or less slow down the time in a precise way, sometimes only affecting the time of specific persons. He can also do it generally.

### Spatio-temporal rifts

It allows him to create spatio-temporal rifts. However, two types of them exist, which are the attack type and the travel type. He masters both.

The attack type spatio-temporel rifts are rifts that kill any opponent on contact with them. Moreso, these ones can absorb the opponents, and can prevent the teleportation and soul alteration of the absorbed person. If the soul of a person has been turned into green beforehand, the person can't be absorbed anymore. He can't create it on people or very near people. He prefers to use them instead of black holes because not only they make less damage around them, but he can also control who they absorb.

The travel type spatio-temporal rifts allow him to travel without any restriction throughout the entire Multiverse, and to go to any AU, anti-void or any place in the Multiverse. To detail more, he can't move himself outside of the Multiverse with them, but he can go anywhere in the Multiverse thanks to them, included locked places, excluding Xénotale and Undertale: The Ultimate Timeline without authorization. Anyone can pass through them without any kind of damage, the only exception being the first one he ever created, this one being unstable. He can also create those on people, making them instantaneously pass through them, useful for quick travel.

### Anti-world

*Main article: Anti-world*

He can make an Anti-world around him, capable of extending itself to an entire AU at maximum, though he can also make a smaller anti-world, or even being precise and making an anti-world on a specific person by touching them. When the anti-world is used on people with statistics, it does damage exactly 299792458 times per second, for a value of 3 damage per time. When it is used on a person without stats, the anti-world progressively destroys the body of a person until the body is in pieces, but only a bit each time the anti-world does this effect, to the point where it takes multiple seconds.

Though this attack is not as powerful as the others, magic shields do not allow to be protected from this ability.

#### Enhanced anti-bones

These bones move completely randomly, but they have the speed of normal ones. Plus, in an Anti-world, they can damage the opponent. However, they need to be summoned with normal bones that do nothing in an anti-world. He rarely uses this ability.

#### Anti-blasters

In an Anti-world, these Gaster Blasters can damage the opponent, and have the same speed as normal Gaster Blasters. However, they need to be summoned with normal Gaster Blasters that do nothing in an anti-world. He rarely uses this ability.

### Yellow magic

*Main article: Yellow magic*

Celerity!Sans mastered yellow magic during his training, that he can use on his bones and his Blasters. It has different effects for each case that also depend of if the yellow magic is enhanced or not:

* Normal yellow bones: Normal yellow bones can be placed at specific places, and create many micro-bones that go at multiple places each at the same time by themselves, but with a strength and speed lesser than that of the normal bones. Any of Celerity's bone can be used as a yellow bone.
* Normal yellow Blasters: Normal yellow Blasters can be placed at specific places and will never fire. Instead, they create plenty of Blasters moving in random directions at a speed lesser than that of Celerity and with a random rotation. These Blasters can pass through matter until they stop and stop to fire one microsecond to thrity minutes after their generation. The beams are weaker and slower than that of the normal Blasters. Any of Celerity's Blasters can be used as the yellow Blaster.
* Enhanced yellow bones: Enheanced yellow bones can be placed at specific places, and can create more micro-bones than normal yellow bones. They can also create normal bones by themselves, being as powerful and fast as normal bones. Any of Celerity's bone can be used as a yellow bone.
* Enhanced yellow Blasters: The enhanced yellow Blasters can not only create other Blasters that are as powerful and fast as base Blasters, but these Blasters can be generated by both the base Blaster itself and its beam. In the case it would be created by the base Blaster, the behavior of the generated Blasters are the same as that of the Blasters generated by a normal yellow Blaster, and in the case they are generated by the beam, they are generated in a random place of the beam and targetting a random direction, firing as soon as possible. Any of Celerity's Blasters can be used as the yellow Blaster.

### Physical immunity

Celerity possesses a code that makes affecting the matter that compose his body impossible in any way, shape or form. This includes manipulation and destruction. For example, it is impossible to extract his DNA or to burn him. However, he can still feel pain and his senses are functional, though considering his extreme robustness and defense, it's nearly impossible to make him feel it.

### Coded immunity

Like for all of Xénotale, Celerity's code is hidden in a place only Zeno has access to. Nobody, or even these person's abilities, can access it, making Zeno the only one capable of affecting Celerity's code (normal damage excluded).

### Reality immunity

Like for all of Xénotale, Celerity can't be affected by an ability that alters reality, unless an inhabitant of Xénotale uses it.
