**Error404!Sans** is one of the two Sanses from Alphatale. He is the self-proclaimed god of the Multiverse, the creator of King Multiverse!Sans and the leader of 404's organization.

## Story

### Backstory

He was one of the creations of the Astral Mother, known back at this time as William. He liked the company of others, but sometimes, his mother was forcing him to come to her so she could experiments on him. One day, a Sans from another AU, called Infected, came to destroy his AU. Him and his brother Adam fought Infected. When Infecetd killed his brother, it filled him with rage and sadness. He tore open a rift to an anti-void called the Mainframe. When he entered in it, he claimed this anti-void and absorbed a part of its code, making him more powerful. He teleported Infected inside the Mainframe, and, thanks to the special trait of this anti-void, he killed Infected. He returned in his AU after his victory, but because of the powers given by the absorption of a part of the code of the Mainframe, he destroyed his AU by his mere presence in it. As soon as he realized it, he returned in the Mainframe, making it his base of operations, with the goal of re-creating Alphatale.

Not long after these events, he created King Multiverse!Sans. He took him under his command, then demanded him to create a god system and to become the king of the Multiverse, so he could become the god of the Multiverse himself.

He destroyed Arttale so King Multiverse would follow the requirements on an advantageous deal with someone.

Error!Sans arrived in the Mainframe. He fought the Sans without a name. During the fight, the Sans stole his name and became Error404. Later on, after the end of the fight, Error!Sans accepted Error404's superiority, and was forced to get under his command. This allowed 404 to create 404's organization.

Not long before the events of *Xénotale: Celerity*, he destroys Chaostale.

### Xénotale: Celerity

King Multiverse!Sans came in the Mainframe to tell him about the most recent death of Infected, killed by Celerity!Sans. He ordered King Multiverse to watch him. He called Error!Sans so he could tell him more about Celerity. This discussion made 404 lose his informations about Celerity's localization.

He ordered King Multiverse and Error!Sans to leave the Mainframe after Celerity and Infected's second battle to think about the situation, with the intent to recruit Celerity in his organization. He got interrupted by Zeno, who proposed him an alliance. He first refused, but got convinced by Zeno's demonstration of power and by his own incapability to do anything to harm him.

Having forgotten that Infected's statue was in the Mainframe, Infected resurrects inside the Mainframe. As soon as he understands it, he orders King Multiverse to leave the Mainframe so he could fight Infected alone. He wins, though it was hard for him. After his victory, he asks Error!Sans to teleport the statue in a blank universe, since he does not have the time to study because of other events. He then calls King Multiverse so he could continue to tell him the story he was telling him before Infected interrupted them.

When The Voice invades the Multiverse, he sees this as betraying the alliance, and decided to eliminate his allies. He sends King Multiverse to fight Celerity.

Later, Celerity, being sent in the Mainframe by Zeno, confronts himself to Error404. The discussion goes well. Celerity explains some details to 404, but then Celerity reveals to him that he must kill him. Celerity kills him before he even realizes something happened.

### Xéno!Frisk's arrival

As soon as Xéno!Frisk appears, he investigates about her with King Multiverse's help, then with Error!Sans's. After the investigation, they leave. Soon after, Zeno comes in the Mainframe to tell him that he wants Xéno!Frisk to become his minion. Zeno tells him about an idea of his right after.

Loving Zeno's idea, he reunites with his minions, more precisely with Error!Sans and XGaster to tell them about it. When they arrive, he tells them that he wants the destruction of Underswap. He explains the plan then sends them in Underfell.

Though everything goes as Zeno intended it, his minions must not know about it, so he just demands them to not team ever again.

### Undertale Psi

He talks with King Multiverse about G's order and about the cult of Chaos. He reassures King Multiverse about what will happen if they attain their goals. Following this discussion, he asks Error!Sans to bring him Infected's statue. However, he doesn't know what to do it with it. Soon after, he gives advices to Error!Sans about getting new minions, while learning more about Error!Sans's relation with Determinatale.

At one point, Celerity comes in the Mainframe to ask him to give him informations for a personal project. Celerity asks him if he knows about Arttale. Error404 tells him everything he knows about this subject. He then asks Celerity to take care of Error!Sans.

## Personality

More often serious than not, Error404 is a person that hates pranks, though he likes a lot to have fun by using others' emotions. He is a person that laughs very rarely unless he mocks someone or something. He has a tendancy to believe that he is superior to others, often because those others can't beat him in a fight. This makes him incredibly confident in himself when it comes to fighting, though he does not let this self-confidence kill him. If he is beaten by someone, this person can get his respect. In certain cases, it is not necessary to gain his respect. He cares a lot about his new name, since it gives him a recognizable identity since the destruction of Alphatale. He often uses blank universes since they are empty, but sees nothing in them besides their utility.

He often is alone -though he appreciates the company of others, as long as he knows the persons he is with- and very discreet. He always wants to be aware of the current events that are happening within the Multiverse. Though it happens rarely, sometimes, he recruits new minions in his organization. He usually tries to convince the ones he tries to recruit, by arguing or by making them fear him. However, when this does not work and in a last case scenario, he manipulates the mind of those he wants as minions. Though it is very rare, he goes in AUs from time to time, and in the end, most of the people that are aware of his existence are his minions. He rarely destroys AUs by himself. He also has a profound hate for betrayals, though he knows that he can easily take care of them by manipulating the mind of the traitor, and if he can't, by eliminating the person.

He is a person of extreme intelligence, with the mindset of a scientist. He can easily get ideas. This makes him being tortured when he lacks ideas, especially when having ideas is necessary. It also makes him very difficult to surprise. His intelligence made him realize that it is impossible for him to re-create Alphatale, and that it could be an idea with bad consequences. Since that moment, he lives for the new goal he gave himself; balance the protection and the destruction of the AUs, his strategy mainly consisting of controlling the destruction of the AUs. This doesn't prevent him to try to kill Infected because of his hate towards him. He is a logic person, and would think if given a logic argument. This makes him open to new ideas. He can also see his own mistakes, but does not tell his minions unless it directly concerns them.

In combat, his self-confidence shows itself. He doesn't hesitate to mock, or to give indications about what he is going to do. He fights in a style that allows him not only to attack, but also to defend himself. He does not give all he has at the beginning unless he considers it necessary. If he fights inside the Mainframe, he activates the special trait of the anti-void only if he lacks another choice, including lacking the time to call for Error!Sans.

## Abilities

### Normal form

#### Dark bones

Bones created by the Astral Mother herself, that have a pure offensive goal, doing a lot of damage. They also are extremely resistant.

#### Blue mastery

The strongest technique of the blue soul alteration. It allows to move whataver he wants as long as it has a soul, and as long as its soul is turned blue, in a 500 meters radius. He can destroy the soul of his opponents in a matter of seconds thanks to that. It has to be noted that he does not have to turn the soul blue himself for it to work, though he can do it himself. It is what he uses to manipulate the mind of others.

##### Mind manipulation

After a certain amount of time of use of the blue mastery on someone, as long as their soul is still blue, he can use the blue mastery to control the mind of the victims. However, he needs to keep the soul of the victim blue for it to become permanent, or for it to stop when he decides so.

This form is highly dangerous, giving him new abilities and combining his own abilities with those of Error!Sans. It also gives him higher statistics, even higher than his G.O.D statistics. He can't use the G.O.D statistics when he uses his form since the G.O.D statistics can't be given to Error!Sans.

#### Master cables

Another enhanced version of Error!Sans's strings, thanks to a combination with Error404's Dark Blasters. Those cables start with being blue and red, hunting their target.

#### Enhanced anomaly detection

He can watch everything that happens in Undertale, in the anti-void 6 and in the Mainframe.

### Voice Enhanced Error666

When Error404 uses the Error666 form, he gets Error!Sans's determination. Since this is case, he can be affected by The Voice, which can choose to make his abilities stronger.

#### Superior damage

Thanks to The Voice's help, the damage he inflicts to people around him are improved, and are of 1909909 per millisecond.

Error666 Blasters that are more powerful than normal Error666 Blasters, and that have a bigger action field.

#### Invisible black strings

The black strings he uses, but they are invisible.

An invisible version of the Master cables, even for 404. They are split, so there is a blue version and a red version. The blue version is made to immobilize the opponent whereas the red version is made to do 190990 damage per second merely by approaching. When they are combined, this activates a big colossal blue mastery field that has a 200 kilometers radius, doing ten times the damage of the activation of the Voice Enhanced Error666 form (19099090 damage per millisecond). They also kill any person they touch when they are combined.

#### Colossal blue mastery

This blue mastery extends itself to a 30 kilometers radius, and allows to destroy the soul in one millisecond.

#### God bones

Indestructible bones that are the way to do the biggest amount of damage that Error404 can do using this form.

#### God Blasters

The God Blasters do 500000 damage, and have an action field so big that they could easily destroy entire planets.

#### True resurrection

Though it is the choice of The Voice, they can decide either to use the normal process of resurrection, meaning resurrecting Error404 and Error!Sans separately, or either another way of resurrection, that can resurrect both of them directly merged together. They can't choose to not resurrect them.

#### Paralyzing scream

In case he has difficulties, he uses the paralyzing scream, which he has complete control over, allowing to prevent the opponent from doing anything, as long as the opponent is in a 1024 meters radius without anything to block the sound.

#### Confusing scream

Like the paralyzing scream, it is a scream that works if the opponent is in a 1024 meters radius without anything to block the sound. This one makes so the opponent has hallucinations.
