Omni!Sans

**Unauthorized editing of this page is prohibited**

**Omni!Sans** is a Sans variant created by **NikkoNijime07**. They’re an Out!Code destroyer that wrecks havoc among any AU (Alternate Universe) that bothers, annoys, or has made a bad relationship with them. While they are a destroyer to AUs that they dislike, they can also be an AU protector to alternate universes they really like. Omni!Sans will often wander around the Multiverse and build relationships with those they like or dislike. Depending on the Alternate Universe’s relationship with them, they will either destroy or protect the AU.

They are capable of using the abilities and powers of their friends that have had their SOUL absorbed by them. They can use Undyne’s spears, Toriel’s fire magic, and can even regenerate themselves instantly through Frisk’s DETERMINATION. However, they can only use two abilities at a time, and are only capable of using those said abilities of the user of that ability is controlling the body.

## Biography

### The Infected Timeline

Omni!Sans was a Sans that belonged to one of the Classic Undertale Timelines, specifically one from the True Pacifist Route. While they managed to receive a good ending, it’s known that not all good things would last forever. Some time after ending the Route, an unknown virus invaded his world, which resulted into cracks beginning to appear everywhere and lead to the world to its oblivion. Resetting the world wasn’t able to fix the cracks.. in fact, it just made speeded the cracks up.

Sans, Flowey, and Frisk were the only ones who knew about the cracks, with Sans and Frisk being the ones who would formulate a plan that would allow them to escape their collapsing world. The plan itself was a dangerous, and saddening one in fact. Sans would have to kill Frisk and absorb their SOUL, and go to the locations where the virus was at its best. Being infected with the virus would kill the host, but with Frisk’s DETERMINATION, there could be a chance that their SOUL will override the virus, and glitch into the void instead of dying.

### The Plan

However, when Sans had started enacting the plan.. instead of only killing Frisk, they decided to also absorb the SOULs of his brother, Papyrus, and their friends: Toriel, Alphys, and Undyne. Sans thought that if they absorbed their souls, they would be prevented from being erased with this world, and would be able to stay alive with them. During the plan, Sans had also taken an item/clothing from each of them, to make it seem like their friends still with them.

Sans then went to a location where the virus was infecting, which resulted into them getting infected as well. Though, the next thing that happened to them was both a relief and a shocking event. Instead of immediately dying, their DETERMINATION was able to overcome the virus, which led to Sans being glitched out of the world, and entering the Void. The plan was a success.

### The Omega Timeline

But, Sans didn’t know what to do now. Which was a big problem, considering that everyone else in his body would get bored and eventually control his body while he was asleep. Out of pure luck, CORE!Frisk had teleported to them, and suggested for them to visit the Omega Timeline through a gray door within the void. They were welcomed with open arms by the other characters who were in the dimension.

Though, despite being satisfied with entering the Omega Timeline, and being able to live safely within it, Undyne, Alphys, and Frisk wanted to explore the rest of the Multiverse. Abiding by their idea, Sans decided to leave the dimension (but visit it sometimes), and continued to explore the rest of the Multiverse, creating new friendships and enemies along the way.

## Profile

### Appearance

Omni!Sans is a regular skeleton that has almost the same exact physical attributes of Classic!Sans. They have black eye-sockets with pupils that can changed depending on who is in control of the body, along with having a set of thick, black lines under their eye-sockets that sort of resemble tears.

Their outfit consists of a worn-out red scarf; with the end being a little damaged, a blue sweater with two purple stripes along the center being tied below the scarf, a white lab coat, a purple robe that is cut to waist-length and displays the Delta Rune in the center, a black tank-top that is tied onto their waist, black shorts with white linings, and a pair of red boots and matching red gloves. The clothes he wears all belong to his friends, in memory of them.

### Personality

Omni!Sans is a friendly, highly social, and impulsive skeleton. They have unusually strong mood swings, and are very emotional; especially when it comes to being reminded of the fact they murdered their friends and family. They’re easily sensitive to what people say, and are also capable of feeling the auras around others for some reason. When stressed out or feeling a really strong emotion, they can accidentally switch personalities (example: Toriel to Undyne, and then to Alphys) and are even more emotional and temperamental at this time.

The SOULs in Omni!Sans often fight for control of the body, mostly Undyne, Frisk, and Sans. Whenever a fight between mental SOULs happens, Omni!Sans may look like they’re talking to themselves, or look crazy in an outside point-of-view. However, when all personalities agree with each other, and cooperate effectively, Omni!Sans can pretty much be unbeatable.

When an AU is in a bad relationship with them, Omni!Sans will do anything in their power to wreck havoc and chaos among it. They usually destroy the whole AU without any fear of consequences, nor thinking about what their actions might do to people. Omni!Sans is chaotic to the bone, and will immediately strike for revenge whenever someone has wronged them. Though, when an AU is in good terms with Omni!Sans, Omni will often visit the AU, talk to the residents, and protect them from harm whenever they ask for it.

When there’s nothing to do, Omni will usually just cause chaos for AUs they don’t even know, for fun. They wander around the multiverse a lot when bored.

### Abilities

Due to Omni!Sans absorbing 5 other souls to save their friends, Omni is capable of having a wide range of abilities, but can only use two of those abilities at a time since their SOUL is only capable of being controlled by two other users. However, Omni’s attacks can be quite unstable (and dangerous) when two of the users who are controlling their body aren’t able to cooperate with each other. You can tell who is controlling Omni just by looking at the colors of their eyes.

* When Sans is controlling, their left eye-socket will have a red iris that has a dark blue ring inside of it. The eye pattern would be the same for the right eye-socket if he was the only one controlling Omni.
* Whenever Papyrus was controlling, their right eye-socket would have a large orange pupil, with the pattern being the same for the right eye-socket if he was alone.
* If Undyne was controlling Omni, their right eye would look exactly like Undyne’s; yellow sclera with black pupils. Same thing for the left eye if it were just her.
* If Frisk was controlling, Omni would have their right eye-socket have a pure red pupil. Both eye-sockets would have a red pupil if Frisk was the only one controlling.
* Alphys, when in control, displays a yellow pupil on their right eye-socket, but will have yellow pupils on both eye-sockets when controlling alone.

* Papyrus
* Undyne
* Toriel
* Alphys
* Frisk

**Gaster Blasters**: Gaster Blasters are skull-like devices that are capable of shooting large beams of energy; which typically results into Sans getting tired after firing a lot of them. They are similar to cannons. Sans can also use these devices to move around, since they are capable of floating.

**Bone summoning**: Both Sans and Papyrus have the ability to summon bones in both midair and from the ground, ceiling, and sides of a room. They are capable of manipulating the size and speed of how fast the bones can move.

**Teleportation/AU jumping**: Sans is capable of quickly traveling from one location to another via teleportation, with Sans referring this ability as “Shortcuts”

**Blue Magic**: Sans and Papyrus both have the ability to turn other SOULs into blue, which can affect the opponent’s mobility in gravity. They can apply directional forces directly onto their opponent’s SOULs.

**Dodging**: Sans has a talent in evading incoming attacks.

**Bone summoning**: Both Sans and Papyrus have the ability to summon bones in both midair and from the ground, ceiling, and sides of a room. They are capable of manipulating the size and speed of how fast the bones can move.

**Blue Magic**: Sans and Papyrus both have the ability to turn other SOULs into blue, which can affect the opponent’s mobility in gravity. They can apply directional forces directly onto their opponent’s SOULs.

**Social Skills**: While being social may not seem powerful, Papyrus’s abilities in friendships and trust allows them to build powerful relationships that might be useful in the long run. He can gather allies very easily, and is able to somewhat influence other entities’ emotions.

**Green Magic**: Not to be confused with healing magic, Undyne has the ability to turn SOULs into green, which binds the opponent in their tracks and prevents them from escaping or moving; it will, however, grant them a shield that can defend themselves against her spears.

**Spear summoning**: Undyne is capable of summoning an unlimited amount of glowing spears in which she can launch them telekinetically, or from the ground. She can also summon yellow spears that change their direction depending on the way they’re facing.
**Fire Magic**: Toriel is capable of summoning thousands of flames midair, and is able to create waves, showers, and expanding rings of fire.

**Yellow Magic (Not Canon)**: Alphys has the ability to turn their own SOUL yellow, which allows themselves to shoot out glowing yellow projectiles that are capable of shooting through a human or monster, the effect when getting hit with the said projectile is a short electrical shock.

**Mini Bombs**: Alphys is able to convert her own energy into small, mobile bombs she can throw, which can be set off whenever she wants. The bombs aren’t that powerful, but is able to act like a flash bang or explosion.
**DETERMINATION**: Frisk’s determination grants them the power to SAVE, heal at SAVE points, and respawn at SAVE points after death. However, in Omni’s case, Frisk is now capable of fully regenerating themselves in an instant after getting injured. They also do not need a SAVE point to respawn in the multiverse now, as they can auto-regenerate in 3-9 seconds.

## Weaknesses

**Mood Swings/Sensitivity:** Omni!Sans is very sensitive when it comes to others talking about them. They are also really sensitive to the auras that radiate around them (positive and negative.) Omni is very dangerous when in a frenzy of panic or stress, as they tend to get highly emotional, and may unknowingly switch personalities.

**Loneliness:** With Omni!Sans having lost their friends many times, Omni has gained a fear of isolation, and hates being alone. Due to this fear, Omni was driven to killing their friends and absorbing their SOULs in order to have them stay with them.

**Attachment Issues:** Omni has severe attachment issues with their friends, which may be a problem for the friends themselves. When Omni is attached to someone, they seem to not care about the other one’s feelings. Omni can get very possessive, and even absorb the person/monster’s SOUL in order to have them be with them forever.

## Relationships

### Papyrus

Despite being killed by the hands of his own brother, Papyrus is still very understanding for Omni’s actions, and is also the most trusted out of everyone to control Omni’s body. The two share a close bond with each other, even though Papyrus was killed. Papyrus is mostly in charge of socializing! Hence why Papyrus is the most active Second-In-Command.

### Toriel

Toriel and Sans have a.. rocky friendship with each other, due to Sans murdering both Toriel and Frisk, despite being told not to. Toriel still tries to forgive Sans for his actions, but the two often resort to not talking to each other, and only communicating when necessary.

### Frisk

Frisk and Sans are good friends with each other, and share a trustful bond with each other that’s just below Papyrus. Frisk and Sans were the ones who formulated the plan to escape their collapsing world after all, and the two have built enough trust that Frisk even lets Sans absorb their SOUL. Frisk is the third most active user who controls Omni.

### Undyne

Undyne is somewhat of an annoyance to Sans whenever she tries to force control over Omni’s body. Undyne is very competitive, and hates to be on standby whenever there’s a fight going on. She’ll often come into control when fights aren’t doing so well for Sans. While the two may bicker with each other, they both are really great friends (when they get along.) Though, she is a little upset with Sans killing her and then absorbing her soul, but she understands where he’s coming from.

### Alphys

Although Alphys was killed by Sans, Alphys hasn’t held any resentment, nor fear around the skeleton. Though, Alphys was really worried for what Sans was doing, since there was a small chance of even surviving the virus to begin with. Alphys cares a lot for Sans, and worries about them whenever they do a risky decision. Alphys is mostly in charge when using new technology, and working out things that involve science and engineering.

### Classic Sans (Enemies)

Classic!Sans and Omni!Sans, despite being from the same AU, hold a lot of resentment for each other. One of the main problems that Classic has with Omni, is the fact that Omni isn’t bothered with wearing his dead friends’ clothes, as well as murdering them. Omni’s problem with Classic is that they hold a feeling of jealousy against them. Omni’s confused, angry, and probably jealous of the fact that his world was destroyed, while Classic was able to let his live. Omni thought it was unfair, since the two were literally the same person, but with different endings.

### UnderSwap!Sans (Best Friends)

With Underswap!Sans’s love for friends, and Omni!Sans also having a love for friends, the two were basically meant to be best friends. Omni likes to be with Underswap due to their lively aura, and positive energy that could make him feel very relaxed and happy. Underswap likes to be around Omni!Sans because he was very confusing, intriguing, and very energetic! He also wanted to be friends with Omni so that they could try and he’ll them with their emotions.

### CORE!Frisk (Friends)

Ever since CORE!Frisk saved Omni from the void by taking them to the Omega Timeline, Omni had always been grateful and friendly with them ever since. Omni would occasionally visit the dimension every once in a while (probably out of boredom) and the first person they would greet would be CORE. The two have a good friendship between them.

### Ink!Sans (Friends?)

When Omni had discovered the Multiverse, they were suddenly greeted by Ink Sans. At first, the two were okay with being mere acquaintances that could get along well, but when Omni had started destroying AUs, Ink decided to confront them about it. Ink secretly finds Omni unstable, and also childish, while Omni thinks that Ink should really mind their own business. The two are just on neutral terms currently, but they aren’t friends or enemies.

### UnderFell Sans (Enemies)

Both Omni and Fell hate each other, and that hatred has started ever since the first day the two saw each other. Fell, like Classic, felt disgusted when seeing that Omni was wearing his friend’s clothes, while also having murdered them. Fell described Omni as a freak, a weirdo, and a psycho. Meanwhile, Omni didn’t like the AU Fell was in to begin with. It gave off the wrong energy for them, so they decided to thrash it (since it was annoying) Omni would describe Fell as a psycho, edge lord, and also a pushover due to UnderFell Papyrus walking all over him whenever they saw him. The hate is mutual.
