The Sans of that universe attempted to keep the universe safe by allying himself with the Team of evil Sanses, but just ended up deepening his debt to them.

GrimmTale: Yet another AU specializing in the spread of madness, GrimmTale is another Twin Universe and is associated with being HorrorTale's Twin, but accusations and the actions of the inhabitants have left people just to speculate, GrimmTale has had a good many number of problems and have been known to kidnap other AU Inhabitants and eat, torture or straight up kill them. GrimmTale has broken many of the Multiverse Laws and is seen as large threat due to how off the grid it is and away from everything else the AU. Killer.Jpg: A different Killer was experimented on by 404, his DT tampered with, and his mind scrambled making him a more reliable slave to 404 then to Nightmare.

Recently, Code Red was approached by many people who wanted to help him, but he refused all assistance and has been living alone for a very long time since. Anti-Void doesn't seem to affect him much, but his fear and the trauma of his destruction of Aus left him in a state where he couldn't do anything. EchoTale-: EchoTale- is a living Paradox, once before the original Echotale; however, after being heavily experimented on by the Defiled Witch and turning the once proud AU into a Omniversal Paradox, wiping the AU clean off of the Multiverse and all forms of it across the Omniverse. However it's paradox like nature was only due to someone attempting to stop the Defiled Witch at the time of tampering with the said AU. "Existing" as it is though allows for Echo- to not only be untouched, but to be connected to everything at the same time. However, them being a paradox would be the least of their troubles as they would be hunted by a unknown being from beyond. Luckily, not only were they hard to track, but Frisk's(Chloe's) newfound ability would help them greatly whenever the "thing". Got too close. A Fatal_Error has Occurred: The story is about the aftermath of a battle between Error!Sans and another Geno!Sans, and Geno became glitched as a result. He then wanders the Multiverse, seeking other Sans to harvest to create his own Papyrus. Rock: Rock suddenly appeared one day and started bothering everyone. The record says that he was always a nuisance to "someone else", but the fact is that Locke is a great harm to the multiverse for disturbing other parasites and even Underfresh. Rock is often a source of conflict, to the point that it's pretty unusual if it's not him, and since the advent of Locke, he's been a major threat to the Multiverse and the King Multiverse. Tint: Created by an otherworldly being from a different reality in Ink's image Tint was made to be Ink's replacement and even set to kill him, but Tint eventually escaped the grasp of this being and lost his memories and creativity in the process, now he searches the Multiverse for others with creativity ciphering and taking in whatever creativity he can in hopes of not just gaining his memories, but also in finding other entities from AlphaTale as well, however when Tint found Ink and 404 he began attacking those two daily and wouldn't stop till he was either the only Ink or 404 was dead. Anti-Flowey: A anomaly and glitch made due to the actions of 404, Anti-Flowey is version of Flowey that has its sights on killing every sans in the multiverse, it has killed over 50 of them and strives for more. However recently he has gotten very passive over the times. Vape: Nothing is really known of this individual, the AU he came from isn't documented nor is it even remembered truly a victim of the way the multiverse now runs [No more Info to obtain]. SynthWave: SynthWave, like other annoying skeletons, suddenly appeared and began to cause problems, but unlike others, it did not harm others, but instead of harming others, it became sober on its own. He is known for soothing others with his strange voice and playing music through headphones to ease his mood. Those who try to kill him usually come back in a different way, rather than taking damage. A.Star Sanses: The A.Star Sanses are a trio of Sans. The three members of Ink, Dream, and Swap are collectively called Star Sanses, but it seems that they are different. The three members are Hollow!Ink and Dead!Dream and Swapfell.W are A.Star Sanses. Sub X: Sub X is not Au, but a cult that still believes in X-EVENT and the events that took place a few years ago. Even after the X event, some Aus who were promised perfection by X-Gaster and swore allegiance to him still deny that it was all over. These AUs are very aggressive and dangerous beings who act according to the "orders" of X!Gaster, even though X!Gaster and X-tale have long since disappeared... At least, that's what they're saying. The Sketchy Universe: Template and Pale is an AU where Error and Ink have swapped personalities. Template protects the AUs while Pale drains them of their life so he can get feelings. Template accidentally messes with the normal storyline in AUs while he is trying to protect them, but he goes to AUs occasionally, so, it happens often. History of Events and the Multiverse The Destruction of the First AU The Destruction of AlphaTale not only became a scar on the Multiverse but would utterly be known as a traumatic moment in its history for AUs would no longer be created equal or as great as they were intended to be, but instead would dissolve into a hellish pit of trying stories and dashed dreams and horrible creations that would take the place of others more deserving. Not only that, but The Anti-Void and Mainframe would now Trapped in a endless void of enjoyment and happiness and all of this would be introduced by the new supposed "First AUs." First AU The first AUs after Alphatale was Correcttale, and many others were created after, which created a pyramid structure that anyone who asks and knows exists, and this pyramid began to form on top of the failures of other AUs, but that would not be all. But that's not all. Failed AUs will be stripped of their prominent parts by other creators and placed in already functioning worlds and universes. This is how the AU survives as it is commonly known. However, the way to maintain this "best" only plunged the multiverse into a spiral of hatred and anger. Many AUs who thought they deserved to be at the top rioted, denying the status quo that had been maintained for many years, and starting to fight with each other, and many AUs broke down and fell apart in the face of something new. The 13 Knights These are the beings that surpass event that's of Fatal404!Sans(FatalGod), OmniBroken!Sans(MajinDistortion), Beyond!Gaster(Base) and even Corrupted!Toriel (50%). They work for there King who is Unknown and has existed before event that of C!Alphatale. Each of the Knights have seen and looked over both humans and monster but are disgusted by there actions and constant squabbles a Example of this is the Human and Monster war which annoyed them to a point where after the Monster were imprisoned. 3 of there member attacked the human race and killed both there king and all 6 sages where they where innocent or guilty. Each member has its own mind and sense of justice. Each member are also from a monster species and about 4 humans. The X-Event The X-Event is something Ink has Started. He Started it Nice and Slowly, it took long, though. Ink is the one who let his guard down and let X-Chara get a soul part and all of the X-event started corrupting timelines and AU's completely resulting in X-Gaster's Alphys to quarantine the corrupted AU's and when the X-Event is at its fullest X-Chara can overwrite the Sans in the final battle temporarily. King Multivese However, a few years later, after the feud between them had subsided, an unknown Sans suddenly appeared out of nowhere and declared himself king and even created a small throne. Of course, this not only sparked millions of people challenging this so-called king, but in turn, people trying to dominate the multiverse. However, Seraphim! Not even Sans could touch or grasp the power of this god-like king. He proclaimed himself the King of the Multiverse, and Righteous!Error bowed to him without question. But Ink! Sans rejected it because he thought it would be better for the multiverse to be free and fight than to be ruled by peace. However, Ink's ideals were shattered by the others present at the meeting, and eventually Ink also became a slave to King Multiverse, and soon everyone knew his name and the person who separated him. But after awhile, Error!404 created Queen Multiverse. The Seven Deadly Sins During the time after King!M and Queen!M were created a group of beings that represents an emotion, there are called the Seven Deadly Sins, this group only has one goal and that is to do anything they wish. They really don't have a leader, or the group doesn't go on missions, rather they just do their business. Each one of them have the power to manipulate a sin they represent. (But also, they are not or related to the Conduits of Lust, Wrath, Gluttony, Greed, Sloth, Envy and Pride and these guys are older than those Conduits). Lust = Lust Wrath = Warth Gluttony = Gluttony Greed = Greed Sloth = Sloth Envy = Envy Pride = Pride Dark Ages Among them, AUs such as Horrortale and Dreamswap were created that symbolized the era in the C!Multiverse. In addition, violent AUs were created, many horrific acts were committed, and for a time there were rumors of illness, but it was later proven that this was the act of one person (probably Chara). The Dark Ages gave rise to hope and myths, which people used to lift their spirits, hoping for a better future and a better time in the multiverse. As sightings of pale skeletons with a blue and tall color scheme spread, people began to call them "white devils." He is a being who strips the world naked, but many people see it as a god-like being, thinking that he has come to cleanse the multiverse from the sick and the distorted and make everything better again. But rumors of a real demon began to appear, it all started with rumors of Horrortale, another version of horror, rumors began to spread that Sans would act like demons, stories of a large purple sphere that would flatten the entire world, rumors of a person who never stopped smiling. Rumors became obscure, mingled with each other, and eventually the figure became known as "MIX" and its identity was revealed. There were also other rumors. Known as the "Ghost of the Multiverse," it cries out for the poor souls of the Multiverse, slaying down all the Outcodes that defy its will and protecting all that is good. However, the figure is bound to reveal its true nature sooner or later. Mother vs father Basically, this is an event where the The Defiled Witch and Beyond Gaster fought. Due to the Defiled Witch mind plus their ability to experiment, she thought it would be a good idea to try it on One of the CorrcectTale Brother. This however ended up making her an enemy of Beyond!Gaster and was almost eliminated by the Anti-Monster/Beast. She luckily escaped before meeting her end and the rest is history. Gods vs. Humans After battling god-like beings for a long time, the AUs eventually began to realize that they were facing the worst enemy they had ever encountered. New enemies, such as the 404 and the infected, begin to rearn their heads, but they're not alone. As soon as the action and fun surged from the presence of the gods, creators began to create their own ideas that could challenge or work with these beings. However, some new AUs began to bloom, and many others that settled in the multiverse soon began to plummet and collapse. The Infected creature tore apart the AU and many other universes, leaving pure chaos in its wake, single-handedly achieving the extinction of the AU in Swapfell, with only a few people surviving. Against these forces of nature, the multiverse felt hopeless, and only the ghosts of the multiverse could fight them off. Teams Teams play a big part in this Multiverse's, some teams (like the Star Sanses) protect AUs or different locations meanwhile some other teams (like the Bad Sanses) one and only goal are goal is to cause chaos across the Multiverse. Star Sanses The Star Sanses are one of the most important teams in this Multiverse as they are the ones that protect AUs and AUs inhabitants. The members of this team being: Ink!Sans: Ink!Sans was the one that formed the Star Sanses and for that he is the proud leader of the Star Sanses. Dream!Sans: Dream!Sans is the second member of the Star Sanes after Ink. Swap!Sans: Swap!Sans is the third member of the Star Sanes after Ink and Dream. Template!Error: Template!Error joined the Star Sanses after proving Ink that he can protect AUs. Cross': Cross or X-Sans is an ex-member of the Bad Sanses and he was originally not going to join the Star Sanses but after some convincing from Dream Cross joined the Star Sanses. Alpha!Sans': Alpha!Sans joined the Star Sanses soon after he became Ink's mentor, and Alpha is the mentor of the Star Sanses. Alpha!Crystal Crystal also joined the Start Sanses with Alpha and become the "mother" of the Star Sanses. Bad Sanses One of the most evil and brutal teams in this Multiverse, the Bad Sanses are the direct opposite of the Star Sanses, instead of protecting AUs the Bad Sanses want to destroy all of the AUs and have complete control over the Multiverse. Nightmare!Sans: Like Ink, Nightmare!Sans was the one that formed the Bad Sanses and for that he is the mischievous leader of the Bad Sanses. Dust!Sans: Dust!Sans is the second member of the Bad Sanses and he is one of the smartest members. Horror!Sans: Horror!Sans is the third member of the Bad Sanses and he is one of the most vicious members. Killer!Sans: Killer!Sans is the fourth member of the Bad Sanses and like Horror, Killer is one of the most vicious members. Error!Sans: Error!Sans is the fifth member of the Bad Sanses and he joined because Nightmare kept on nagging him to join the team. Cross (Formally): Cross is the only Bad Sans member to leave after he found out being one the good side is better than being on the Bad side. He also left because he betrayed Nightmare. Insanity!Sans: At first Nightmare didn't consider Insanity a member of the Bad Sanses, but after he helped the team out on very important mission, Nightmare finally consider him a member of the Bad Sanses. Shattered!Dream: This variant of Dream traveled the same path as his brother from the original Dreamtale, Nightmare finds him one of the most important members of the Bad Sanses and Shattered!Dream is a secondary leader of the Bad Sanses. Rules of the Multiverse If a Killer enters your AU, you are allowed to eliminate them without consequence. Such actions will not be deemed criminal by the King of the Multiverse. If another AU character enters your AU by accident, you are permitted to assist them in returning until King Multiverse intervenes and resolves the anomaly. No entering Undertale. No disturbing the more prominent AUs. No genocides of other worlds. No AU or timeline invasions. No Glitches allowed in AUs, the Omega Timeline and the Doodle Sphere. Swaps or normal AUs aren't allowed to be within reach of each other. Glitches are banned from ever interacting with normal AU assets or other beings. 404 and many others associated with him are wanted and hunted. If a Killer enters your AU, you are allowed to kill them, and you will not be titled as guilty of anything. If another AU character somehow manages to accidentally get into your AU, you may help them find their way back until King Multiverse is notified and resolves the problem. All Killers are to be killed or destroyed on sight if they break any rules unless the King makes an exception. Stealing things from other AUs is illegal and can have you be sentenced to imprisonment depending on what you stole. The Natural Laws of the Multiverse Cause and Effect: Any cause within the Multiverse is known to have an effect and everyone is usually bound to them. This law is also the cause of why timelines exist within a Universe and what enables the quantum mechanics in the Multiverse, as any action or inaction creates a new branch in the Universe, causing a quantum reaction, and another timeline to be made. It is one of the many factors that make the AUs the way they are and allow creators to have more creativity by getting new ideas from the timelines of any AU they may have made, which they can also modify as long as its their own AU. Code: Code is a natural part of the Multiverse that makes up most of it. It is treated as the essence that makes up the Multiverse. However, codeless things can exist within the Multiverse, but they will usually be viewed as "anomalies" or "unique creations". AUs that support the Multiverse: The Multiverse has pieces of creation within them that maintain certain concepts that help the Multiverse. An example of this is DreamTale maintaining the concepts of positivity and negativity within the Multiverse itself and is usually what's needed for these concepts to exist, with everyone within the Multiverse gets affected by these. Dispersion and Reformation: This happens when an AU is around for a long time, and eventually will collapse, with its energy and code dispersing. This same code and energy will eventually reform itself with the help of the Mainframe and will reform the AU in the process. It can either; make it brand new, recreate the one from before, will be left over for a creator to use and make their own AU as a replacement, or the energy will be taken back by the Mainframe for a potentially different purpose. Error!Sans possesses several unique abilities. He uses a special type of Gaster Blaster called an Error Blaster, which is larger, faster, and stronger than Classic Sans’s Gaster Blasters and features black coloration with blue tear marks flowing from the red eye sockets. He can also create blue strings from his tear ducts that he uses to tie up and shatter souls. If these strings enter a victim’s body, Error!Sans can transfer his soul into the victim, causing the victim’s soul to vanish and the victim to transform into Error!Sans, effectively controlling the victim’s body while rendering them helpless. This ability is his main weapon since Error!Sans has poor eyesight and relies on the strings for combat. He can also glitch himself and others into different alternate universes as his primary method of multiversal transportation. Error!Sans has complicated relationships with several other characters. He once captured Swap!Sans (also known as Blueberry or Blueberror), whose pacifist and eccentric nature clashes with Error!Sans’s merciless attitude. Swap!Sans shows Error!Sans the same mercy he offers everyone, despite Error!Sans’s selfish behavior. The Anti-Void also affected Swap!Sans, causing him to become glitched as well. Error!Sans is wary of CORE!Frisk, even though CORE!Frisk once saved him from deletion; he still believes they are anomalies that must be destroyed, along with their Omega Timeline. He has many enemies, including Error!Undyne, who pursues him for allegedly killing Alphys, and FATAL Error, a corrupted counterpart he accidentally created and now battles. Though they have no official canon relationship, Error!Sans and Ink!Sans often clash due to their opposing views on the Multiverse: Ink!Sans believes it should remain untouched, while Error!Sans views it as an abomination. Error!Sans also has a mentor named Error404!Sans, and a bitter rivalry with King!Multiverse!Sans, both created by the same fan artist, though these relationships are not canonical within Error!Sans’s original storyline. Error!Sans suffers from haphephobia, the fear of being touched, making him hesitant to get physically close to others. His eye sockets can randomly glitch, filling with errors and putting him at a disadvantage in battle. He is nearsighted, which contributes to his reliance on his blue strings in combat. If Error!Sans were to be unglitched and restored, he would likely commit suicide out of guilt for his actions. Due to the nature of the Anti-Void and its connection to all existence, Error!Sans can theoretically appear anywhere beyond the boundaries of the Undertale Multiverse. After the cancellation of the ErrorTale AU, the character was reused and redesigned for CrayonQueen’s original work, Lucidia, with significant changes to his story and appearance. Fresh sans: Fresh is an Out!code characterized by a color scheme reminiscent of a 90s cinema floor. He wears sunglasses that normally display the word "YOLO," but the text changes to reflect his current thoughts. A parasite inhabits his right eye socket, and although he speaks with the laid-back slang typical of a stereotypical surfer—using words like "brah" and "rad"—Fresh is not truly a Sans himself. Instead, he is the parasite controlling a Sans skeleton by living inside one of its eye sockets. Fresh struggles to understand emotions other than fear because his parasite nature prioritizes survival above all else, though he is still capable of experiencing other emotions. In appearance, Fresh is usually shown as a Sans skeleton with white bones and black eye sockets. His right eye socket contains a white pupil, while the left socket often features a purple upside-down heart-shaped pupil. He wears a red backwards cap with a cyan propeller that spins faster or slower depending on his emotional state. Fresh dresses in a pink polo shirt with an open collar revealing his sternum, topped by an unzipped multicolored sweater featuring purple, blue, white, and orange hues. The upper part of the sweater is blue, the lower part purple, separated by a thick white stripe with a blue wave pattern. He sports green and blue pants with yellow zippers that can shorten them, cyan fingerless gloves, a red fanny pack emblazoned with "SWAG," and white heelies with blue dots and pink soles. His socks are pink and slightly oversized. Fresh has a single gold tooth among his otherwise white teeth. His black sunglasses obscure his eyes and display different words based on his thoughts, such as "yolo," "woah," and "rad." His height is not officially confirmed, but the creator Crayon Queen has stated that he is taller than both Geno and Error!Sans, often towering over others. Fresh’s true form is a small purple parasite with five tentacles and a central mouth/eye. Because Fresh is a parasite inhabiting a host skeleton, he does not have the typical abilities of Sans characters. However, he can enter and control other Sanses who do not have souls, such as Ink!Sans, a fact that terrifies Error!Sans. Fresh’s abilities include censoring swear words by replacing parts with “fresh” slang like “rad” or “funk,” pulling explosive furbies from his fanny pack that detonate in colorful explosions, teleporting while leaving behind a colorful cloud labeled "FRESH POOF," and using the powers of whatever host body he inhabits. His primary weapon is a baseball bat. Fresh was heavily inspired by the character Dippy Fresh from Gravity Falls, as revealed during one of Crayon Queen’s live streams. Fans often react to his appearance with dismay, saying, “Oh God, not him!” According to Loverofpiggies, Fresh’s birthday is April 20th (a 420 joke), but Fresh himself opposes drug use and pretends his birthday is April 1st (April Fools’ Day). He also appears in the “Christmas Party AU” comic. Fresh tends to invade people’s personal space, touching others excessively due to a lack of boundaries. Despite being called “Fresh Sans,” he is technically not a Sans but the parasite controlling the host skeleton. He enjoys annoying Error!Sans and loves to rap. Fresh keeps a notebook where he records the names of people he has kissed and has a furby that he treats like a pet. His gender matches that of whichever host body he inhabits. Reaper : Reaper Sans is an ancient and enigmatic being who embodies the very concept of death itself, acting as the God of Impure Death alongside his brother, Reapertale Papyrus. Created by the god of magic, Gaster, Reaper Sans exists not only as a skeleton but as a near-omnipresent force, weaving through the fabric of reality as the ultimate reaper of sinful souls. His skeletal figure is cloaked in a flowing, tattered black hooded robe, reminiscent of the traditional grim reaper, complete with a loose rope tied around his waist and neck, from which hangs a small Gaster Blaster — a symbol of his deadly power. He walks barefoot, his presence silent but imposing, while sometimes manifesting massive black wings that allow him to effortlessly glide through the Reapertale Void, his home and domain where he rules over death’s endless march. Standing at about 5’4, his bone-white skeleton contrasts starkly against his dark attire, his form both ghostly and divine. Despite his godly stature and near-immortality, Reaper Sans is a being scarred by tragedy and inner turmoil. For countless eons, he has dutifully reaped the souls of the impure, a task he never desired yet accepted as his fate. The weight of his role gnaws at his fractured soul, especially after the accidental death of the one he loved, a loss that fractured his sanity and left him haunted by guilt and sorrow. Though Toriel’s kindness helped him regain some semblance of sanity, he remains partially insane — a god tormented by his own existence. Reaper Sans is calm and reserved, often hiding his true feelings behind a veil of dark humor and sarcastic puns, yet his fear of dolls, clowns, and especially Gaster, reveals the cracks beneath his grim facade. His relationship with those around him is complex; while he dislikes his job, he strives to maintain control, though moments of uncontrollable rage and temporary madness do surface, a reminder that beneath his godly power is a deeply troubled soul. Reaper Sans’s abilities are staggering in scale and devastating in effect. As the embodiment of death, he wields power beyond mortal comprehension — his touch alone can instantly kill almost any creature with a soul, bypassing all forms of natural durability. His signature weapon, a colossal Gaster Scythe, is an extension of his will, capable of cutting through the very essence of life and death, and can be summoned or controlled with perfect mastery, sometimes even extended with a chain for deadly reach. He manipulates darkness and gravity with ease, able to summon black holes and shadow clones to overwhelm foes, and cloak entire timelines in suffocating blackness. His flight is not limited to wings alone; Reaper Sans can levitate effortlessly, teleport instantly across vast distances, and his non-corporeal form renders him untouchable, allowing attacks to pass harmlessly through him as if he were a ghost. Immortal and timeless, he neither ages nor truly dies, capable of reincarnation or resurrection should he ever fall. Despite his overwhelming power, Reaper Sans has weaknesses — the purity of untainted souls saps his strength and vitality, making him vulnerable and sickly when confronted with such light. This paradox of existence, where the god of death can be weakened by purity, adds a tragic layer to his eternal vigil. His presence is often marked by the consuming void around him, the very air thick with despair and the weight of countless lost lives. His personality balances a grim sense of duty with moments of surprising warmth; he enjoys coffee, puns, and holds a rare fondness for figures like Papyrus and Toriel, despite his otherwise solitary nature. Yet beneath this veneer lies a being burdened by endless responsibility, haunted by his past mistakes, and trapped in a cycle of death and rebirth within the Reapertale Void. In the greater narrative of Reapertale, Reaper Sans stands as a complex figure — a god burdened with both immense power and profound sorrow, a being who is at once feared and pitied. His story is one of sacrifice, madness, and the unending struggle between fate and free will, forever intertwined with the souls he must guide to their final rest. He is the silent watcher at the edge of existence, the grim arbiter whose scythe swings not out of malice but necessity, forever caught between the duty to reap and the desire to redeem what little of his shattered soul remains. Geno : Geno Sans, also known simply as Geno or Aftertale Sans, is a male skeleton monster from the Underverse and Aftertale universes, created by LoverofPiggies, also known as CrayonQueen—the same artist behind Error Sans, Fresh Sans, and the Christmas Party AU. He originates from a Genocide Route timeline in which he previously served as a Sentry, a Hotdog Vendor, and a Royal Judge. Currently, he resides in the Save Screen, though at times he has appeared on the Surface. His alignment is chaotic good, and his morality is heavily shaped by trauma, guilt, and isolation. Geno uses he/him pronouns, is single, and is sometimes referred to by other names such as “Geno” by others in the multiverse. His story begins in Chapter 2 of the Aftertale comic and concludes in Chapter 9, though his character continues to appear in related projects like Underverse and later arcs such as the Fatal_Error storyline and AskError. Physically, Geno shares the basic skeletal form of Sans but has notable visual differences that reflect his damaged and deteriorating condition. He stands at approximately 4'10", with 0 HP and minimal stats, having 1 ATK and 1 DEF. He wears a white hoodie and matching slippers, a deviation from the original Sans' blue jacket and pink footwear. Beneath the hoodie is a plain white shirt and short pants. His body shows clear signs of corruption and damage: a massive bloody gash runs down his chest from the fatal slash inflicted during the Genocide timeline, with blood occasionally dripping from his mouth and staining his slippers. He wears the iconic red scarf of his timeline’s Papyrus, which he treasures deeply, often treating it as if it were his brother himself. Geno’s right eye is obscured by a white glitch-like particle, part of the fragmented, unstable code that clings to him since arriving at the Save Screen—an unintended side effect of injecting himself with Determination. The glitch hides a portion of his skull that is literally melting away, a result of the unnatural Determination coursing through him. He deliberately placed the particle there to conceal the extent of his physical damage, especially from Sans and Frisk, so as not to frighten them. These particles can be controlled at will and emit a white, digital shimmer, emphasizing his fractured state. Geno’s personality is deeply shaped by the trauma of the Genocide Route and the immense guilt he carries over Papyrus’ repeated deaths. Once the timeline was overtaken by a genocidal Frisk, Geno—then still Sans—watched Papyrus die through one of Alphys’ monitors. In a desperate attempt to stop the madness, he injected himself with Determination from the True Lab, but his plan failed. While he gained the ability to remember every reset and timeline, he couldn’t stop Frisk and was ultimately slain. However, instead of dying completely, he escaped to the Save Screen, where he became trapped, neither fully alive nor fully dead, his status flickering between “dying,” “alive,” and “error.” Adopting the name “Geno” as a grim reminder of his failures, he is now confined to the Save Screen, able to influence the living timeline only through his counterpart Sans, who unknowingly serves as his anchor. Over time, Geno’s moral center has eroded. His isolation and lingering Determination have made him emotionally unstable, desperate, and dangerously manipulative. He often erases Sans’s memory repeatedly to reset his attempts at persuading him, resorting to psychological pressure or even torture through memories of previous timelines. Despite his cold and calculating nature, Geno retains fragments of his old personality—he still makes puns and exhibits humor, particularly in his first encounters with others. He displays violent tendencies when provoked, especially regarding Papyrus, whose memory he guards obsessively. If anyone touches the scarf, he reacts with intense fury. When Sans once brought Papyrus to visit the Save Screen, Geno lost control of his emotions entirely. Though his ultimate goal is to destroy the timeline to free Papyrus and others from their repeated suffering, his extreme methods and volatile behavior make his intentions deeply questionable. Geno’s relationships with others are layered with conflict and emotional tension. His connection with Sans is paradoxical; they are technically two versions of the same person, and Geno does care about Sans’s well-being, yet he is not above manipulating him ruthlessly to achieve his own goals. He sees Sans as his only means of influencing the timeline, and if Sans refuses to help him stop Chara and erase the universe, Geno will erase his memories and start again. His relationship with Frisk is similarly complex. Initially, Geno intended to kill Frisk when they appeared in the Save Screen but changed his mind, seeing them as a tool to manipulate Sans. Over time, he allowed Frisk to play with his Gaster Blasters and even made efforts to appear less frightening around them. Whether this was genuine compassion or another layer of manipulation remains unclear. He refers to both Chara and Frisk as his murderers, blaming them equally for the Genocide timeline’s devastation. His hatred for Chara is particularly intense; his plan involves Sans bringing Chara to the Save Screen so that Geno can disable them, push them into a coma, and return to the Underground alone to erase the timeline once he becomes the one with the most Determination. Geno’s abilities mirror those of the original Sans: teleportation, Gaster Blasters, bone attacks, and gravity manipulation. However, due to the Determination injected into him, he possesses enhanced capabilities, such as resisting the effects of resets and being immune to time’s passage within the Save Screen. He can also bring others into the Save Screen, though seemingly only when they’re in physical contact with Sans. His control over glitches allows him to hide his decaying form and even manipulate his surroundings subtly. With a high Determination level, he is capable of remembering resets and—if conditions allow—erasing the timeline altogether, surpassing even Flowey’s influence, though still falling short of Frisk or Chara's Determination. In the larger multiverse, Geno plays a pivotal role in several spin-offs and alternate stories. In the Fatal_Error arc, Geno is attacked by Error Sans and, due to the fact that death is impossible in the Save Screen, becomes an even more corrupted and unstable entity known as Fatal_Error. In another divergent path, he is transformed into Error Sans himself after willingly entering the Anti-Void and losing most of his memory and self in the process. Error retains no knowledge of his past as Geno but continues the cycle of destruction. In these futures, Geno becomes either a monster that hunts AUs or an empty shell driven by bitterness and isolation. Despite this, there are still timelines where versions of Geno experience peace or happiness, suggesting his fate is not universally tragic. By the epilogue of Aftertale, Geno appears to receive a "happy ending" and glasses from Alphys. However, unable to rest and driven by his Determination, he sends himself to the Anti-Void in an attempt to rid himself of lingering guilt. This leads to his final transformation into an Error. The emotional weight of his final thoughts—remorse, anger, and self-loathing—shape his corrupted form, turning him into a destroyer of worlds, yet even then, his actions stem from the same deep, unresolved grief that began with the loss of Papyrus. Fell!Sans (Red) : Fell!Sans, also known by several aliases including Fell, Edge Lord, Edgy, Red, Pepper, Rustle, Dog, and Nega Sans, is an alternate version of Sans from the Underfell AU created by Vic the Underfella. He is a skeleton monster, male, and uses he/him pronouns. As in the original Undertale, he serves as the Judge in the Judgement Hall and works as a sentry, but in this universe, he also sells chimichangas. He resides in Snowdin and aligns with a true neutral moral stance. His exact age and date of birth are unknown, but he is currently alive and single. His place of birth is the Underground, and in the Genocide route, he dies in the Judgement Hall after confronting the protagonist. Physically, Fell!Sans closely resembles the original Sans but has several key differences. He is short and stout like his Undertale counterpart but has more pronounced eye bags from chronic lack of sleep and constant stress. His left eye glows red at all times due to his emotional corruption and instability, and it occasionally flickers to yellow or orange. He has a set of sharp, pointed teeth with one gold tooth on the left side. Unlike the original Sans, Fell!Sans frequently sweats—not for aesthetic reasons but because he overheats under his thick winter jacket. His outfit consists of a black, flame-furred jacket with a gray hoodie and a red sweater underneath, sometimes adorned with a gold chain. He wears black basketball shorts with yellow side stripes and red sneakers or slippers. The fluff on his jacket collar is more wild and jagged compared to the soft collar of the original Sans’s coat. His constant emotional pressure radiates through his magic, which causes his jacket fur to ripple or shimmer unnaturally. This jacket was a gift from Grillby, who gave it to Sans after laughing at a joke—accidentally or otherwise. In terms of personality, Fell!Sans is far more jaded, guarded, and aggressive than his original version. He is sarcastic, emotionally repressed, and often appears cold or uninterested. He doesn’t enjoy puns like the original Sans, but has a notable appreciation for knock-knock jokes. He strives to present himself as cool and composed, rarely showing outward emotion, and is very rarely flustered. He has a noted allergy to cats. Despite his harsh demeanor, he carries deep guilt—especially over his younger brother Papyrus. He feels as though he’s failed him, believing that Papyrus no longer needs his protection and even sees him as weak or useless. Though they bicker constantly and try to outdo each other as the “cooler, more mature brother,” they care deeply for one another but avoid talking about their feelings. Their bond is close yet emotionally distant, marked by sarcasm and stubborn support. Fell!Sans’s history includes working with both Gaster and Alphys as a royal scientist. A turning point in his life came when he insulted Asgore and was nearly killed for it. Papyrus intervened, saving his life at great personal cost—he was scarred by Asgore as punishment. Though Papyrus was rewarded with a place in the Royal Guard, Sans was deeply traumatized by his inability to protect his brother. He went on a rampage in the laboratory, killing monsters in an effort to protect them both. This act cemented the change in his personality and reinforced his inner conflict. In terms of powers, Fell!Sans is slightly stronger than the original Sans. He can use red and orange bones, summon red Gaster Blasters, teleport, and manipulate living souls via telekinesis. His attacks are magically enhanced, and while his stats are listed as 1 ATK and 1 DEF, he is incredibly dangerous in battle. He also holds in immense emotional stress that manifests as leaking magical energy, especially around his eyes and clothing. In the True Pacifist timeline, Fell!Sans initially mistrusts Frisk and watches them from the Judgement Hall. Though hostile at first, he ultimately refuses to fight after seeing Frisk’s mercy and determination, coming to recognize a purpose in their actions. In the Genocide route, however, after losing Papyrus, Sans becomes emotionally broken. He confronts Frisk not out of hatred but with grim acceptance of their mutual adherence to the world’s rule of “kill or be killed.” He thanks them for showing the world’s true nature and, after seeing they won’t back down, fights them with all his strength. He dies after twenty-four rounds of combat. In some fan interpretations and fangames, Sans breaks the rules of the game to kill Frisk after the fight, preventing the Genocide route from progressing. Fell!Sans has various relationships across the AU. With Papyrus, he shares a love-hate dynamic fueled by guilt, admiration, and miscommunication. With Frisk, his relationship evolves from hatred to reluctant respect, depending on the route. He’s friends with Toriel, and he previously worked with Alphys and Gaster in the royal lab. He has an unusual transactional relationship with Grillby, paying his tab in socks, which Grillby begrudgingly accepts. In one moment of levity, Sans once wore Papyrus’s boots and described the experience as “feeling alive.” These small moments of humor hint at the softer core hidden beneath his hardened exterior. Epic!Sans : Epic!Sans, often called Epic or Memelord by fans, is a powerful and enigmatic figure within the multiverse, notable for his distinct black and purple trench coat emblazoned with a Half-Soul design and a striking white ribbon on its back. Standing at around 5'6", he has a skeletal form typical of his kind but marked by a unique scar on his left eye socket, which normally remains empty but glows with a fierce purple light when he is emotionally charged or focused. This magical eye is the source of much of his extraordinary power and grants him an inability to truly die, making him nearly immortal unless the eye itself is taken, a feat only possible by his creator, Epic! Gaster. Despite his casual and often lazy demeanor, frequently punctuated by his trademark catchphrase “Bruh,” Epic! Sans is highly intelligent and serves as a royal scientist, combining sharp wit with a deep understanding of magic and bone manipulation. His arsenal includes the devastating Epic Blasters—large dragon skull-like weapons that fire destructive energy beams capable of leveling forests—and advanced bone magic that surpasses his classic counterpart in scale and power. His blue magic enhances his telekinetic control over souls, allowing him to move and slam opponents with considerable force without needing to use his hands. Though he often adopts a laid-back attitude, he is fiercely loyal and protective of his friends, willing to sacrifice himself if necessary. His relationships are varied, with close bonds to characters like Cross! Sans and complicated ties to figures such as Asgore, Papyrus, and Alphys. Epic! Sans's long history is marked by a fusion with Gaster, which initially granted him his powers but also cursed him with relentless nightmares and an ongoing internal struggle against the eye’s influence. Over more than two decades, this torment forged him into one of the most battle-hardened and experienced Sans variants across timelines. His combat style blends brutal efficiency with surprising creativity, sometimes even wielding unconventional weapons like a rubber chicken in melee. Despite his immense strength and near-immortality, his greatest vulnerability remains the magical eye, whose removal would strip him of his power and life force. In sum, Epic! Sans is a figure of paradoxes—relaxed yet serious, powerful yet vulnerable, meme-loving yet deeply scarred by trauma—making him one of the most compelling and multifaceted characters in his universe. Outertale!Sans : Outertale Sans, often called Outer! Sans and affectionately nicknamed Space, Outer Moon, Cloud, StarryStarshineSunshine, is a significant character originating from the Outertale universe, created by 2mi27. He serves as a judge figure within his story and holds a lawful neutral alignment, balancing duty with personal morals. Standing at a petite 3.5 feet and weighing as light as a feather, Outertale Sans’s skeletal frame is adorned with a distinctive yellow jacket featuring blue stripes and a soft cotton-lined hood, complemented by blue trousers and his trademark pink slippers that add a gentle, cozy touch to his appearance. His overall look, with the fluffy-lined hoodie and slippers, reflects his approachable yet somewhat shy personality. Despite his diminutive size, he carries the weight of serious responsibilities as a sentry on Stardin, a space-themed location that shapes much of his identity and worldview. Personality-wise, Outertale Sans is caring and supportive, showing a deep loyalty especially toward those he trusts, like Frisk. His warmth shines through in his fondness for blueberry and strawberry nice cream, small comforts that reveal a softer side beneath his vigilant exterior. While he enjoys humor and puns, much like classic Sans, his demeanor can shift dramatically depending on circumstances—particularly during the Genocide route where his attitude hardens, and he becomes a harsh judge toward those who harm others, especially those who kill his brother Papyrus. This duality makes him both approachable and formidable, a complex figure who values mercy but won’t hesitate to confront injustice. Outertale Sans shares a close sibling bond with Papyrus, who in this universe is similar to the classic version but with altered stats that emphasize his resilience. Their relationship is one of mutual care but also sibling rivalry, with Sans often playing the role of the protective older brother while juggling feelings of guilt and responsibility. His connection to W. D. Gaster is unique—he is one of the few who remembers Gaster and Papyrus's past and played a role in Gaster’s creation, which indirectly protected his brother and shaped their upbringing in the vastness of Stardin. In terms of abilities, Outertale Sans wields the traditional Gaster Blasters and bone attacks, though his powers seem tinged with a cosmic flair befitting his space-based origin. He displays teleportation skills and exceptional spatial awareness, demonstrated in moments such as using his blasters to destroy Error’s strings during a critical encounter. Despite his potential, his life is tragically cut short in Underverse episode 0.4 when Killer! Sans fatally strikes him, marking a poignant moment in his storyline. His HP is modest at 3, with attack and defense both at 1, but his true strength lies in his strategic mind, quick reflexes, and the celestial energy that colors his fighting style. Outertale Sans embodies a blend of classic charm and space-themed mystique, balancing humor and heart with a serious sense of duty. His life and actions reflect the tension between lightness and the harsh realities of his universe, making him a memorable and emotionally resonant character within the wider Undertale multiverse. Science!Sans : Science!Sans is a highly intelligent yet socially awkward version of Sans, characterized by his scientific curiosity and analytical mindset. Unlike the more laid-back and lethargic Classic Sans, Science!Sans is energetic, enthusiastic, and often quite talkative—especially when it comes to scientific subjects. He has a youthful demeanor, mirroring some of Papyrus’s excitable energy, and is known for his quirky sense of humor, often using knock-knock jokes to lighten tense moments. Despite his good intentions, he can come off as morally gray, sometimes making manipulative or strategic comments—like claiming that “friendship is the easiest way to control the masses”—indicating a utilitarian streak beneath his friendly facade. Visually, Science!Sans typically wears a white lab coat and is often seen with safety goggles or glasses, emphasizing his role as a researcher. In the Christmas Party AU, his look changes to a festive green sweater that reads “MERRY MATH-MAS” along with reddish-tinted spectacles. His left eye glows green and displays complex math equations when he activates his powers, which is a unique trait among Sans variants. He is slightly shorter than Underfell Sans and shares the skeletal structure of other Sans characters, though his posture and expressions tend to be more animated and expressive. Science!Sans is both endearing and eccentric. He often struggles with social boundaries, as seen in his awkward interactions with other characters like Fell Sans, whom he appears to admire or even have a crush on. At the same time, he is deeply uncomfortable around more chaotic or unpredictable characters like Fresh Sans, who frequently harasses him. While he projects confidence and ambition—such as declaring himself the "Minister of War"—he also reveals moments of vulnerability, self-doubt, and emotional sensitivity. These layers make him a richly developed character who balances intelligence with insecurity, ambition with awkwardness, and science with sincerity. More other sanses; 6. Negative!Sans 8.
