HyperDust is a variant of Murder!Sans who becomes intensely attached to fighting the player after hundreds of timelines. When he notices the player taking longer to return after each death, he fears they’ll disappear forever. Desperate to keep their “game” alive, he steals the player’s soul during a Hardmode run, absorbing it and forcing the timeline to stop in its track, as he's sent to the void where he struggles to stay focused due to the pain the soul is causing him. which leads chara to take interest in his actions, prompting them to appear once more, as the fun has only just begun. hyper is also the owner of the casino and is cold and serious

Possession Sans is one of three game-pass characters that need to be purchased in order to be used or gifted to you by another player. This character requires you to do a lot of multitasking between managing yourself, your corpse flowers, and your Venus Blaster. Keeping your Venus Blaster alive and in a good position is essential as it provides great camping potential and damage, with it having a long cooldown upon death as well. Additionally you must remember to place down your corpse flowers, as they give you bonus healing, speed, and area control in their poisonous glass clouds.
Possession is an AU where Flowey can possess, or take over a single in-game character. Sometimes he can possess two, and sometimes more than two.
Everything is also the same. The only difference is that Flowey can take over a character. The most common target that Flowey possesses is Papyrus. The rare or least common ones are the other characters, like Undyne and Gaster. Sometimes their possession doesn't work. The reason why Flowey always possesses Papyrus is because Papyrus is stronger than Sans (in health, defense, attack, etc.). Another common target is Papyrus's brother, Sans. The reason for him possessing Sans is because his abilities are much stronger than Papyrus's (Karmic Retribution, dodging, gaster blasters, etc.).

Crossbones (TS!Underswap Sans) is the vigilante hero of the Starlight Isles along and is the brother of TS!Underswap Papyrus. He is the replacement for Underswap Sans's spot as a gamepass character and released on the Casino Update. His price is higher than Underswap's was, but players that already owned Underswap got Crossbones for free. EXP gained with Underswap can be transferred to Crossbones or stay with Underswap.As the masked vigilante Crossbones, he is very serious and dutiful in his heroic efforts of protecting the Starlight Isles and it can be assumed that the same could be said for capturing humans. However, the names for some of his superhero gear can sound somewhat immature, mainly his "bed sheet of justice" and "Punishment Shack", and puts on a dramatic and stunning persona when he's wearing the mask. Crossbones prefers to keep his identity a secret and seems to be rather worried about his identity being exposed.
When off duty as his civilian persona, Sans, he tends to be laid back and a joker, who also knows how to deal with his brothers' child-like outbursts. He also likes pranks, especially when it's using Papyrus' own gadgets against him. He may act different while he's off duty to avoid drawing in any suspicion. However, he shares his identity with those he trusts, with Papyrus being a notable example, whom he likes to spend time with. He will also reveal himself as Sans to the protagonist towards the end of Starlight Isles on a Neutral route by removing his mask shall they prove themself a good person. He follows this up by saying they're always welcome to his home shall they not go through with their adventure and even offers them to hang out at his Punishment Shack.
As mentioned above, humor and comedy are traits Sans showcases both in and out of costume, as his encounters with enemies such as Koffin-K and his henchmen show him taking the matter rarely, if not at all, seriously. He only really seems interested in making sure no harm comes from their mischief shall it ever happen and humors them in doing so. Other scenarios have Sans wearing a fake mustache along with his mask, riding the "Crossmobile" (a small tricycle) during a race, and repeatedly exchanging 1G with the protagonist over changing the channel on his TV until they put the money in their mouth so he won't take it back.
That being said, Sans takes his role as the protector of the Starlight Isles very seriously when push comes to shove. He does not like the idea of murder, hence why he prefers harmless gag-like gadgets over real weapons. He is acutely aware if the protagonist has hurt any monsters and isn't afraid to confront them over their actions. He is also very observant, as shown on the Ruthless Route; Sans will notice the dust on the protagonist's clothes during a brief confrontation he makes in an attempt to scare them. In addition, he will drop his humorous side as means of getting across how serious the situation is, which immediately gets Harry and Larry to comply after a foolish attempt at provoking the protagonist.

Dustbelief Papyrus is the last obtainable character. He is a very polarizing character, as some hate him, some think he's a "fraud", and some think he's absolutely busted; in reality, he can demolish weaker teams and more inexperienced players, but stronger players can win if they try hard enough; teams are probably the weakest against this character, since past the Box Attack your team is probably decimated anyways. He deals insane damage and has 4000 HP (in reality, he only has 2000 HP, since Charas deal 2x damage.). He gets more powerful after using his Box Attack. A Phantom Dust Sans assists you [Upgrade 2].Dustbelief Papyrus is based on Undertale Papyrus, with a tall and slim skeletal figure. His eyes are typically large and hollow, however during battle he gains an orange pupil in his left eye and a green/blue pupil in his right.
His expressions usually bounce between a dead, blank expression and a confident, slightly crazed appearance. While most of his outfit is new, he keeps his red scarf and boots. He wears a large trench coat with a tall popped collar and blue rolled up cuffs that expose his arms, under his coat he wears a blue shirt with a brown satchel carrying multiple containers for his dead friend's dust. He wears dark navy pants tucked into his boots and brown large gloves similar to his previous red ones.
He can most often be seen also holding some sort of weapon, typically an orange bone sword with a skull for the hilt.
This Papyrus is caught between his break in sanity and his normal self, and as such he has seemingly schizophrenic episodes where he balances between a caring yet troubled skeleton and a bloodthirsty, vengeful monster. Thrust into needing to kill as many monsters as possible to stop the human, he has gone insane and has felt less and less remorse. His murder spree is for the sake of his brother first and is his last stand against the human. His loss in sanity is merely a result of his fragile skeleton heart suddenly being compelled by his brother to murder for the sake of revenge on the human. As he loses emotion, he becomes uncaring and cool-headed, but is still deeply insane and upset.
Despite this, he does seem to regret killing those who were close to him, specifically Sans and Undyne, as when he accidentally killed Sans in self defense, he blamed himself until blaming Frisk, and hallucinates a ghost of his brother to cope with his death. He was already insane by the time he killed Undyne, but he apologized and respected his fallen friend by putting her remains in a jar on his bandolier.

Green Sans is a Sans Team Character from the collaboration between Undertale: Last Corridor and Awesome Games. Green Sans comes from the hit Undertale fangame, GREEN SANS.Sans, trapped in a repetitive cycle in his timeline, decides to change his fate by seeking to become the second strongest in the underground. He immerses himself in physical training, even giving up his beloved ketchup for milk to strengthen his bones. However, his body begins to give way under the pressure, suffering recurring nightmares and weakening physically.
After months of training, he discovers his stats have barely increased. Despite this, he faces the amalgams that have rebelled, confronting them with determination. Though he fights bravely, his body weakens and Snowdin is laid waste by the battle.
In a final effort, Sans manages to endure, turning to ashes before being reborn, his soul complete. With white eyes and newfound determination, he defeats the remaining amalgams, including the former royal scientist and his father, Gaster. Despite being on the brink of collapse, Sans finally finds what he was seeking: a challenge and a new experience in his life.
BEEP, BEEP, BEEP
It was a dream....
time to get Mcdonalds!
Green is strange and antisocial, although he is a good person once you get to know him. However, when he fights and no one is watching, he becomes more self-assured. When he gets serious, he can make beings tremble who don't even know fear. He becomes deeply irritated when no one except his friends remembers him.

Epic Sans is a character of the Epictale AU. Epic Sans wears a black/purple hoodie with an upside down heart on the back. He is also heavily associated with anime, memes and the word "BRUH" a lot. He is the last character you can unlock before performing a reset. His damage is high, some of them have AoE damage, but his attacks are very easy to spot and use a lot of stamina, however most of his attacks can do chip damage. Epic! Sans wears a black and purple long-tailed trench coat that features a Half-Soul design and a white ribbon on its back. He wears black gloves that allow his fingers to show. For his bottoms, he wears black striped pants that are tucked into his boots.
Most of the time, the left socket where his scar is will be empty, but a magical purple eye will manifest when he's emotionally stressed, focused, or trying to intimidate others.
He loves to say "Bruh" often, occasionally replacing words with it. He is generally lazy and casual, similar to classic Sans. He gave himself the title of "Epic!Sans" just because it sounds cool. If in the right conditions, he can become a nerd comparable to that of Alphys. Epic! Sans tends to be a huge flirt to anyone he finds cute. Whenever he's around his best friend Cross (From XTale), he often engages in meme related antics.
When the situation calls, he can be serious and shows uncharacteristic maturity when doing so, despite the omnipresent appearance of his favorite phrase. Epic! Sans isn't the kind of person who easily forgives, especially when he's betrayed. He'll fight for his friends even at the cost of his life if need be.
In the original story, Epic! Sans was a fusion of Sans and Gaster, which is how he got his scar. His personality as a result was 90% Sans and 10% Gaster.
In the reboot, he's mostly the same, except he isn't fused with Gaster at all. As the royal scientist, he's quite intelligent.

Insanity was a character with decent stall and close-ranged potential. Insanity specialized in hard hitting punishing easy to dodge attacks that allowed him to stall and gain Stamina, with his Lethal rush and Slams allowed for camping, while Slam and Death Wave dealt unavoidable damage if close enough and not baited. Sans was experimented on by Dr. W.D. Gaster, who attempted to set monsters free from the underground by taking the DETERMINATION of from a human soul and finding a way to safely inject it into monsters. Through several experiments of trial and error, Sans was the first patient to not undergo amalgamation. This led to him moving to the second phase of the project; honing the power of DT. He was able to learn the functions of the SAVE file and was shown how DT influenced his magic, through Asgore's trainee royal guardswomen, Undyne. Over several months, these sessions became less frequent, with Sans slowly becoming more isolated. Small thoughts of why Gaster had left him isolated for so long turned into resentment for him, as he grew more determined to find out why. This spiralled into a violent killing spree, lost from its' original goal.

Killer Sans is a very strong character when utilized correctly. Killer has a large amount of Stamina, and hard-hitting attacks. Killer can deal huge amounts of damage if the Chara team isn't careful. His best example being Goop Blaster, one of the hardest hitting, if not The hardest hitting single attack in the game. Killer!Sans looks similar to counterpart, Classic Sans, except for his color theme being different.
Outfit: Dull/Darkened blue jacket with a fluffy hood (often depicted as having a black stain on the chest), black turtleneck, shorts with inverted colors, shoes instead of slippers (sometimes with no laces or untied ones). However, despite this, he can be seen wearing a normal outfit which Classic Sans wears, too (always during Something New timeline/comic), making it canon to draw him with the standard Sans outfit.
Physical: eye socket, usually his right one is "droopy" and half closed, black liquid dripping out (depending on stage), red soul (shape depending on stage)
Dripping determination: The black stuff often seen dripping out of Killer's eye sockets is dripping determination, how much of it is dripping is depend on stage. Higher the stage, Higher is amount of dripping determination. Killer!Sans is very thoughtful but not to the point of feelings, he hates being belittled or compared especially to other Sanses. (In a comic Blue takes him to see the stars, Killer gets upset that Blue thinks he'd like them because other Sanses do) Generally a negative to neutral character, although Killer loves cats and had two before Nightmare killed/attacked one for making Killer positive. Killer also seems to suffer from some type of personality/identity disorder similar to DID. He'll have little breakdowns and freak outs when he's beginning to feel again and is reminded of the pain he's caused. Not only that but he also has a shadow-like hallucinations (like Papyrus, Chara, Frisk, etc) that will sometimes appear to him, possibly symbolizing his guilt going into overdrive as his sins crawl up his spine. He's hard to read and often unpredictable, his emotions are often suppressed or out of control, when they are regulated however he has a difficult time with them, often feeling numb or upset. He is often in pain. He very rarely eat food and tries to avoid Ketchup and Chocolate because it brings back memories. Because of so many resets Killer Sans sometimes can't recognize what is real or not. Hardest enemy he fights is his brother. It is possible that Killer Sans is intentionally trying to avoid his Home timeline because of his guilt. Stars are reminding him of resets.

Storyshift Chara (also referred to as; SS Chara or SSC) is the 21st unlockable win character. SS Chara is an incredibly strong, hard to learn character. They are extremely melee oriented, and will struggle against zoners. Storyshift's most important attribute is Bloodlust, which empowers their attacks. Chara is a human child clad in a worn pink shirt with patches sewn in, a brown jacket, faded dark blue pants a single large patch, and dark brown shoes. They have unkempt medium-length brown hair with short bangs. They also have naturally rosy cheeks and brown eyes. Jaded and cynical with a deep hatred for humanity, Chara shows a downbeat and world-weary demeanor. They act as a voice of reason within the duo, reigning in Asriel's more impulsive tendencies. Despite their cold exterior, they demonstrate a capacity for compassion and empathy, showing sympathy towards Dogamy's situation and setting aside time to play with Lesser Dog.
Though they initially resent Frisk due to their aforementioned misanthropy,[၁] Chara gradually warms up to them as they continues to defy their expectations.

Aftertale Sans (sometimes referred to as After or Geno Sans) is a Character from the Sans team. This Sans noticeably has a glitch effect in his right eye. He also has a huge cut on his torso and his mouth is bleeding. He has a white jacket, white shirt, Papyrus' scarf, black and white shorts, white slippers, and a sad expression on his face. Aftertale sans (otherwise known as Geno) is an OC created by LoverofPiggies or CrayonQueen, also known for making Error Sans, Fresh Sans, and the Christmas Party Comic. Geno is a Sans from a Genocide Route timeline who, after watching the death of his brother Papyrus over one of Alphy's cameras, injected himself with determination from the True Lab in an attempt to control the timeline, this did not work however, and while he was able to now remember every time Frisk died and came back, he was powerless to stop them, eventually being struck down, and only barely surviving by escaping to the Save Screen. He is now secluded to the Save Screen, unable to leave without facing near instant death, only able to influence the world through his replacement, the Sans of the next timeline, who he can influence in a variety of ways.
Geno is one of the most prevalent characters of the Aftertale comic, being a supporting character and antagonist to the protagonist, Sans.

Horror Sans is a decent sans team character, his damage output is absurdly high and can melt Chara team members in seconds, however his low stamina and lack of easy hits cripples him. However, after his skull got broken and a part of his magic was taken by the now insanely violent Undyne, something within Sans changed. Sans instigated a new rule by Undyne, where humans who fall down are to be consumed for survival. After this, Sans was no longer the joyful skeleton he once was. According to the bunny, despite the rule he himself implemented, Sans has not eaten anything for 7 years, which then led to him losing his kindness, along with his sanity.
After many years of hunger Sans is seemingly bored of everything, even though the dire situation has damaged his psychological state severely, as he now seems to enjoy psychological humor and every bit of Aliza's screams. Whether it be Papyrus's puzzles or the hungry people of Snowdin or even himself torturing her, he has no sense of morale or seems to care about right or wrong; his jokes have changed from annoying yet funny to dark, insane and sadistic, reflecting his attitude.
He loves to decapitate humans for fun, usually using them for "head-dogs". Sans follows his own rule, which is to never eat a human, despite being the one who implemented it, and tries to prevent Undyne from finding out about Aliza's existence. He also shows regret and sadness over realizing that he almost gave into his hunger and tore out her arm to eat it, only for Papyrus to stop him via letters that told him not to eat anything that moves. This could somewhat prove that Undertale Sans is still somewhere inside the insane and starving skeleton. He is seen as the more psychotic of the bunch, even though he manages to speak and have normal conversations. Sans in fan works is mostly portrayed as a blood hungry and feral brute, that socializes very rarely, a far call from his Undertale counterpart though sometimes he's portrayed as a more psychotic version of Sans. Despite his psychotic tendencies, he sometimes shows signs of loneliness or hopelessness, mostly around his friends in Snowdin and sometimes even around his brother due to his introverted disposition.
Later it is revealed that although insane, Sans had been trying to earn the respect of the Snowdin Townsfolk by protecting them from Undyne and helping them find food.

Hardtale Sans is an incredibly powerful character that deals heavy damage through the use of combos. Hardtale is an incredibly tanky sans, though has few tools to keep the chara team away from him.HardTale Sans (also known as Hard!Sans) made his first appearance in Megalovania Hardtale, an animation published by CedDrawsNear on the 24th of March 2016. This Sans is a take on the Hard Mode version of UNDERTALE, that instead of taking place in original timeline, gets fleshed out into a full on Alternative Universe (AU).
During the animation of his introduction, we see HardTale Frisk exiting the Ruins, with Sans standing right next to them, ready to fight. After a short dialogue "Let's get this over with...", a fight between them both iniciates, this fight is short yet clean for the time it was posted on, displaying Hardtale Sans attacking while HardTale frisk dodges and strikes back, just like a normal UNDERTALE battle.
This fight goes on for 1 minute until Sans gets tired and decides to spare Frisk by saying: "Say kiddo, how about we call it a day?". HardTale Frisk accepts, and spares Sans leading Sans to end the battle and for them both to quickly become "friends", as HardTale Sans says "i didn't really wanna kill you" implying that he simply was trying to kill HardTale Frisk because it was his job.
Since his original debut, the character has gained good amounts of popularity, earning hundreds of pieces of fanart, fan-songs, fan-animations and even getting a youtube series made by his creator that tells the tale of the HardTale AU, including Sans's one.
Contrary to what some people believe, HardTale Sans does not have the biggest impact on HardTale's story, just like Classic Sans on pacifist.

Ruins Dusttale Sans is a fairly competent character. Vengeful Rend grants good mobility and camping potential as the fireballs left behind linger, while his fireballs and dusty zones cover a great area and deal great damage. However, Ruins Dust is very susceptible to getting rushed by weapons such as Horror Cleaver very easily. "Ruins Dust" is a version of Classic Sans that has finished killing all monsters in the Ruins and is about to exit the place. This stage of the Dusttale Sans series of characters is the lowest and the weakest, having about LV 3.
This version represents Dust Sans in the Ruins, after dusting Toriel.

Last Breath Sans is the tenth character you can unlock in ULC. Last Breath is one of the most technical and skill based characters in the game currently, with his bone ricochete and bone sliders needing active attention to use properly. However using LB correctly results in a very strong character worth the effort of trying to understand. (Last Breath) Sans is a main character in the Alternate Timeline, Undertale: Last Breath by Zerjox and Team Imagination. This is specifically a version of Sans from the original Undertale, caught up within the events of a new timeline that ultimately takes a new path, straying away from the typical genocide timeline.

Outertale Sans is the ninth Sans Team character in the roster. They are a strong character when used correctly, having a multitude of combos at his disposal to deal huge damage in a short amount of time. Use attacks like Aerial Star Blaze and Cosmic blasters to defend yourself. Using Comet Carnage a distance away and forcing people into range with Aerial Force Jab, or alternatively using Gravity Reverse to keep them in place and use Black hole Blast + Cosmic Blasters for big damage.Sans also has a supporting, caring personality. In Outertale, Sans cares for his love of Frisk much when Frisk supports mercy.
However, when Frisk does a Genocide Run, Sans' personality changes. He becomes concealed. Like Undertale Sans, he judges the player very harshly.
Sans also likes puns and tells them so much to the point that it annoys his younger brother, Papyrus.
Outertale Sans is also sometimes depicted as a bit shy.

Underfell Sans is the eighth unlockable Sans Team character in the roster, he comes from the AU Underfell. Underfell Sans has INSANE base and KR damage, at the somewhat cost of his Stamina, this mainly applies to Phase 1 with Upgrade 3. Underfell relies on his chained move to reel in players and land devastating damage to them.In the past, Sans worked with Gaster and Alphys as royal scientist
Then at some point in the past, Sans was about to have his skull crushed by Asgore but was stopped by papyrus, and impressed by his speed and bravery he told papyrus that in most cases he would have had him punished severely for his heroism, but instead offers a job in the royal guard. Asgore tells him that if he does so, his brother will be left alone, and so he agrees to only being grabbed by Asgore, saying that his act of defiance would not go unpunished. He carved 2 scars into Papyrus, and enraged, Sans made several attacks but was stopped by Papyrus, enraged that Sans had such abilities but only did anything until after Asgore was finished. Sans kills some monsters on laboratory to protect himself and Papyrus.

Sans is the older brother of Papyrus, and is a major character in the Undertale AU UnderSwap by P0pc0rnPr1nce. In this AU, instead of being a laid back, lazy, and smart skeleton like in Undertale, Sans has a role in the story and personality more similar to that of Undertale Papyrus.

Underswap Papyrus is the seventh unlockable character in the roster. He comes from the AU Underswap and is a somewhat strong character for both early game and end game, however he is not the easiest character to use correctly and can get overwhelmed quickly. His first phase has a defensive move-set with his Bones Waves and Stomp Bones acting as his main camping moves, with his blasters as his main offensive tool. Papyrus is laid back practical jokester who enjoys drinking honey, and sells corndogs as a side job. In Underswap, Papyrus' personality is much like that of Undertale Sans, however he does keep parts of Papyrus' Undertale personality, such as being more emotionally volatile and active than Undertale Sans.

Classic Sans (also called Undertale Sans/Bad Time Sans) is the sixth Sans Team character in the roster. Classic comes from the original game Undertale during the No Mercy Route. Classic has many offense and defensive options, good mobility, and devastating KR. His Bone Assault both Aerial and ground variants along with Shortcut allow him to increase his inherently lower mobility, and his other attacks hit hard with KR. Chara's can break some of Sans's attacks by swinging their weapon or with certain abilities. classic is just normal sans, his au is normal (neutrual) and hes pretty lazy

UndertaleIPapyrus, also referred to as; UT Papyrus, or just Papyrus, is the fourth character on the Sans Team. He requires 6 wins to unlock. He is considered a strong character early game and generally pretty solid late game. Papyrus uses a variety of bone attacks, with his Bone Throw dealing great damage, and his Great Leap providing mobility, along with Bone Gap allowing for many devastating combos with his other attacks, potentially dealing huge damage. same as classic sans, his au is neutrual and hes sans younger brother

Science Sans is the third unlockable character in ULC. He costs 4 wins. Science is a very complex character, with tons of variations of his attacks. With multiple traps that can be placed on walls, potions of varying effects, and multiple drones to deploy. He can also lower Chara's max HP with his DT Extractor passive. However he is somewhat limited by his lack of mobility options, but his camping and damage make up for it.
A younger version of Sans when he was the royal scientist. Rather than relying on his magic, he uses prototypes and various gadgets and potions to make his foes fear the battlefield itself. If his gadgets fail to break the enemies, the mind games he plays on them surely will. A younger Sans working with Alphys to track the anomalies. He is a lot more excitable, quite like his younger brother, and even has his 'googly eye' movements. Overall, he is a lot happier during this time. Some facts that point towards Science!Sans within the game are the 'joke book inside a quantum physics book inside a joke book inside a quantum physics book', Sans's secret room, and Sans's ability to alter space/game files to teleport at will. He still has his abilities to teleport, summon bones and Gaster Blasters, like his future self, Classic!Sans.

Pacifist Sans is the second character on the Sans Team. He requires 2 wins to unlock. He is considered difficult to upgrade despite his low EXP requirements due to being one of, if not the weakest characters in the game, but can be very strong once Joking Aside is unlocked. Like Littletale Sans, he heavily relies on stalling and using his Ketchup ability to regain stamina, and has a few attacks that deal relatively okay damage

littletale sans // little sans
The youngest member of the Sans team. Despite not being the most experienced with his powers as most of the other Sanses, he does have a few upsides. He is proficient at recover Stamina through distancing, as well as area coverage through his bonezones. He isn't the most dangerous Sans around, but underestimating him is ill-advised.
