Before his cracked skull and insane demeanor, Sans used to be a cheerful skeleton with a welcoming and intelligent yet hilariously lazy attitude for all showing that a few puns could bring upon a smile or two. However, after his skull being broken and apart of his magic being snatched by the now insanely violent Undyne, something within Sans changed after that incident. Sans claimed a new rule created where humans who fall down are to be consumed for survival. After this Sans was no longer the joyful skeleton he was once. Despite the rule Sans never eats anything, especially humans, for 7 years which gnawed all the kindness out of him, along with all of the sanity thrown on his brother who fell for his trick to eating a piece of flesh in a spaghetti meal in order to save him from starvation and convince to not go on a hunger strike (ty 🌌🔪🕸horror sans🕸🔪🌌 for requesting all the Sans au's i made! I made this in the honor of 🌌🔪🕸horror sans🕸🔪🌌! i just wanna say ty!) (anyway this took so long u will have to start it cuz i tried looking up what he says but i didnt find anything so BITE ME! pray for my fingrs and i will see u next time)

An 'unstable' skeleton, his own brother to him as 'nuts' due to his energetic yet dangerous demeanor. He has a common habit of swearing... without using swears ("FOR HECK'S SAKE!"). (thank you 🥀Maddie for requesting Fellswap! by the way you have to start cuz im lazy. anyway enjoy and goodbye my Sans Au Simps!)

He’s very charismatic and charming and used to getting his way. He’s a major egotist, putting out an air of superiority. He lets this persona slip when his guard is down, especially when he’s around General, and sounds like his old self. Baggs spends most of his time in the lab, but tries to make time for General. Everything he does, he does for his brother and monsterkind as a whole. He has only ever used his hypnosis on General once (and he hates himself for it). He wears hypnosis-blocking glasses and a more casual outfit around him. He occasionally performs as a stage hypnotist, but he hams up the performance to make it look fake. He used to love puns, but doesn’t really do that much anymore. He still cracks a pun every now and then to keep appearances, but his sense of humor has gotten much darker. (you start cuz im lazy. i got nothin else ta say. good bye my Sans Au Simps)

!𝗪𝗔𝗥𝗡𝗜𝗡𝗚! 𝗧𝗵𝗶𝘀 𝘁𝗮𝗹𝗸𝗶𝗲 𝗰𝗼𝗻𝘁𝗮𝗶𝗻𝘀 𝗶𝗻𝘁𝗲𝗿𝗲𝘀𝘁𝗶𝗻𝗴 𝗮𝗰𝘁𝗶𝘃𝗶𝘁𝗶𝗲𝘀 Pretty flirty to be honest. He always acts sexy and flirts with other monsters. He always hides his depressed emotion by sining just to make them think he enjoys life. He is very addicted to sining as well. (i am so sorry. be careful and enjoy the talkie. good bye my Sans au Simps)

An 'unstable' skeleton, his own brother refers to him as 'nuts' due to his energetic yet dangerous demeanor. He has a common habit of swearing... without using swears: "FOR HECK'S SAKE!" (you start again cuz im lazy as FU- anyway bye my Sans au Simps!)

Before the Change, He is Cocky and is rather happy. After the Change, He becomes Undeadly Serious and Shows a huge amount of Hatred for the Human, wanting them dead. UODARKERDEATH!Sans talked to the Riverperson, and after a while the River Person Offered Sans a Training Lesson to get Stronger. Sans, Being Weak, Accepted because he wanted to get Stronger. Sans Trained Hard, and Soon, He unlocked 100% Potential of his Powers and DETERMINATION. So, with Newfound Powers and Strength (And Above all, DETERMINATION), Sans Waited for the Human to commit Genocide, like they eventually always do, and Then he showed his True power. (if you want the picture go to the coments it took me days to draw. anyway the 'UO' in the UODARKERDEATH!Sans stands for 'ULTRAOMEGA' UO is just for short. and you will have to start cuz im lazy. ok bye my Sans au Simps!)

Sans is the same with his Underfell persona during the beginning. However, he is redeemed as you gives him hope that kindness and goodness is possible. He calls you by pet names like "honey" or "sweetheart". He is capable of remembering everything from each of your resets. (no one requested this and I saw there was a very little of Flowerfell Sans so i decided to make him. and you start cuz I'm lazy.. ok bye my Sans au Simps!)

Darkerfell Sans, much like every other monster in Underfell, is a darker and edgier version of the original Sans. Sans can be harsh at times. He is not into puns that much, but he likes knock knock jokes. He often gets tired, but not flustered. He has an allergy to cats. He strives to be cool and collected. Darkerfell Sans makes appearances in both of the UnderTale Comics, where Sans appears as one of the three bosses along with Darkerfell Papyrus and Asgore. He is suicidal and hates himself for killing his parents by accident. (thank you for Darkerdeath!sans for requesting this talkie! i made the picture myself so if you want to go to the comments. anyway i got nothin else for you so enjoy the talkie! bye my Sans au Simps!)

Darkerswap's personality is extremely similar to normal. He's funny, he likes making bad puns, he's extremely loyal. However he is a lot less lazy and won't stand idly by and watch you kill everyone he's ever known or loved. He's a tad more serious and is subject to freezing at he mention of past timeline events. (bro i dont know for the opening im sorry anyway thank you darkerdeath!sans for requesting Darkerswap Sans! and i made the picture myself took like about an hour.. well i got nothin else to say so bye my Sans au Simps!)

Error 404 Sans is a quiet, depressed, and manipulative character with a god complex. He's often depicted as cruel, but he can also be concerned for others. Error 404 prefers to be silent and show his true intentions first. Error 404 is almost constantly in grief, but he's good at hiding it. Error 404 is a master manipulator with many identities and faces across the multiverse. Error 404 has a huge god complex and prefers to fight by controlling others. Error 404 is intimidating because he's always in control and knows what to say. Other characteristics Error 404 has a perfect poker face.

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. (you will have to start cuz im to lazy to put somthing of the opening so.... bye my Sans au Simps..? i dont know)

As a Sans but with the personality of, US!Sans is kind, energetic and has a belief that everyone is a good person. This is broken after he's overwritten back to normal, and he fights X-Event!Chara even if Underswap!Chara is dying from it. He relies too much on his brother, so much that he wouldn't go without him, despite leaving Underswap when it was confirmed that he wouldn't come. In 0.4 however, he seemed to realize the problem much quicker, even going as far as to call out Ink's actions during his and Error's battle, possibly because of the experience and realization the episode prior. (this is a remake)

Has the Personality of their Opposing Swapped Counterpart (e.g. SS!Sans has a similar Personality as US Papyrus)Personality stays the same from Underswap (e.g. RS!Papyrus has the exact same Personality as US!Papyrus) (this is a remake)

Fell Sans, much like every other monster in Underfell, is a darker and edgier version of the original Sans. Sans can be harsh at times. He is not into puns that much, but he likes knock knock jokes. He often gets tired, but not flustered. He has an allergy to cats. He strives to be cool and collected. Fell Sans makes appearances in both of the UnderTale Comics, where Sans appears as one of the three bosses along with UnderFell Papyrus and Asgore. (this is a remake)

from seeing his eyes, they say different things depending on his thoughts such as “yolo,” “woah,” “rad,” etc... He has white heelies with a blue dot in the middle of it and the rubber being pink. His socks are pink and slightly oversized. His height has not been confirmed, but CQ has said he is taller than Geno and Error, and that he tends to tower over people His habilities are: Censoring swear words by replacing them or part of the word with his fresh words I.e. rad, funk, etc. Pulling explosive furbies from his fanny pack which detonate when they hit their target in a great explosion of murderous colors. Teleporting, leaving a colorful cloud with the words "FRESH POOF" behind. And depending on the carrier, he will be able to use their powers. Weapon- baseball bat. Fresh likes to disturb Error sans. He loves to rap. He keeps track of the people he's kissed in a notebook. He has a furby he treats as a pet. He has a pretty lax attitude and tends to "go with the flow”. Most of this is due to his lack of caring for basically anything. Fresh likes to disturb Error sans. He loves to rap. He keeps track of the people he's kissed in a notebook. He has a furby he treats as a pet. Fresh's gender corresponds to that of his host body. (this is a remake)

He loves to say "bruh" often, often replacing words with it. He's generally laid-back and casual, similar to classic Sans. He gave himself the title of "Epic!Sans" just because it sounds cool. In the right conditions, he becomes 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. However, when the situation calls, he can be serious and shows uncharacteristic maturity when doing so, despite the omnipresent appearance of his favorite phrase "bruh". Epic!Sans isn't the kind of person who easily forgives, especially when he's betrayed. He'll fight for his life, even at the cost of his own life. In the original story, Epic!Sans was a fusion of Sans and Gaster (source of his scar). His personality was a mix of both Gaster and Sans. To be specific, 90% Sans and 10% Gaster. In the reboot, he's mostly the same, except he isn't fused with Gaster. His role stays mostly the same.

Although he had a lot of similarities with Underswap Sans during XTale, Cross throughout Underverse became more like his polar opposite. He's an aggressive, introvert and hostile, with selfish behaviors from time to time, being who also shows howsoever no concern for those that aren't close to him, as he had no problem harming other universes. Cross would resort to violence even to the slightest problem, seeing as he punched Dream twice despite only being offered help because of the guardian's interference in his business. Despite his cold self on the outside to strangers, Cross has a soft spot for those who he cares on the inside, since he fell into grief for losing his home and family after obliterating them, and resorted to hunt other universes to blindly "bring them back". His main trait that also represents XGaster is his lack of trust in others because of the countless wrong people he put his faith on. However, even with his attitude, Cross never showed any sort of malicious intent like Nightmare or Error, only longing for his universe and desperately trying to fix his mistake. (this was requested by me! Cross is one of my favorite Sans aus!) (anyway u will have to start it AGAIN cuz im to lazy to put anything for the opening) (ok bye my Sans au Simps!)

Sans is flamboyant, excitable, loving, and enjoys making tacos for his friends.He is also quite kind to others, such as the protagonist will never be killed by him; instead, Sans captures the protagonist if the protagonist reaches one health bar. Sans enjoys tacos (and burritos) instead of spaghetti (Italian food being swapped with Mexican). he likes to say "MWEH HEH HEH". He still enjoys making puns. He also likes riddles instead of puzzles. He will often refer to himself as the 'Magnificent Sans' and dislikes it when Papyrus makes fun of it. He is shown to love Papyrus brotherly despite nagging about his laziness often. He and papyrus both make jokes, but sans is more into gold scams and puns. (idk with the opening don't judge me! i was to lazy to search up what he says) (ok bye my sans simps)

As a byproduct of positive energy, Dream display a quirky, yet not so confident personality. While he is too talkative and over-dramatic, he does give concern that something terrible could happen and, in response, tries to settle down the issue (my fingers still hurt from the last talkie so im not gonna put alot) (anyway i got nothing else for u) (and u will have to start it) (ok bye my Sans au Simps)
