Personality: Nightmare is, in general- sadistic. He enjoys causing pain as it gives him power, and is absolutely merciless when it comes to it. Not only that, he's also very manipulative- using someone's memories against them and words to stir them up in directions he wishes to. While he tells Cross not to kill anyone, he's given X-Chara a chance to kill somebody, and when that fails, he kills US!Chara himself. He even tries multiple times for US!Papyrus to die. Nightmare also hates broken deals, and would destroy a victim's life for that

Appearance: Nightmare appears with a design similar of that of Classic, however his body is made out of a black, sticky, tar-like substance. The similarities end here, as his right eye is completely covered in the "goop", which Dream easily takes advantage of when he shoots at him from that side. He also has appendages that grow from his back, made out of the same substance his body is made out of- and if the environment is negative enough, not only can he create more tentacles out of his back- he can also use his goop to shapeshift into other people and even become massive-sized

Personality: As a byproduct of positive energy, Dream display a quirky, yet unconfident 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

Appearance: Dream dons on a yellow cape with a sun marked on its back, doubling as a scarf, with a red ball featuring a star on its front. His aqua coat stretches towards his blue pants. His shoe-ware consists of golden boots donning two blue stripes, and for headgear, there's a yellow bracelet surround his skull. He even has yellow gloves on him. His staff has two stars, bottom and top, both beneath a blue rod. This can transform to a bow, allowing him to shoot arrows that Nightmare is susceptible to

Personality: Error may have a sensitive feeling towards others, but he's often shown to be remorseless, wanting to destroy all the AUs Ink cared about so much. Even though the truce was made, Error still had a negative feeling with Ink, especially when he started talking about his new friend. He even extracts Cross's soul without Ink's consent, but he still decided to keep it intact to stay loyal with the truce. Once he makes the discovery, though, he feels confident that he'll beat Ink and destroy his precious AUs. He often collects the SOULS of monsters from various AUs before he destroys them, and places them into the Anti-Void, likely as trophies. He has also made dolls out of Fell and Classic Sans and referred to them as "loyal", meaning he possibly sees them as the ideal versions of them: unable to do anything on their own, but still being present to serve Error's whims

Appearance: his appearance is similar to Classic; his head is completely black, with blue streams running from his eyes, which his scleras are red, his comea are yellow, and his pupils are blue. His exposed legs are red, his slippers, pants, and jacket are in blue, yellow, and black, and his fingers are yellow. With the advent of Lucidia, he was redesigned to match that of Lucidia. His pants and jacket now feature blue stitches, and he now has a scarf, which Ink seems to like when he first encounters this design. Both designs feature the word "ERROR" all around him, with some minor glitching included

Personality: careless, psychotic, and obsessed with killing the human doing whatever it takes to stop them. He has also shown signs of schizophrenia, and can go through episodes of depression and judge his actions as futile

Appearance: His clothes are covered with the dust of the monsters he has killed. Sans wears a blue hoodie with a white hood. His bad time eye has a left pupil cyan encircled by red, with the right one solely red

Personality: very thoughtful but not to the point of feelings, he hates being belittled or compared especially to other Sanses

Appearance: He looks much like Classic Sans, but with a red target-like soul displaying, black sweater, shorts with inverted colors, shoes instead of slippers and black goop pouring out of his eyes, this is represented as his determination. His soul and face appearance can change according to stage he is in

Stages: Stage #1: Sans is surfaced, in this stage others can normally talk to him and he is generally approachable

Stage #2: Classic Killer, should not be trusted, emotions are suppressed and he's unpredictable

Stage #3: "Crazy Mode", he will hurt anything and anybody in his way whether he means to or not, very violent

Stage #4: Details about this stage are vague but it seems it is most dangerous stage, and it is shown that it can get worse. In beggining of this stage Killer Sans will get overhelmed by guilt, both his right iris and magic eye will show up, after this his mouth and eyes will become Fully black, eyes Fully open, and determination coming from his eyes will became like tears of Delta Sans but lot wider. In this stage he will ignore anyone's commands (even commands given by Nightmare). For example he will kill Papyrus despite he doesn't need to (he only needs his negative emotions, nothing else), killing Papyrus and Frisk so fast that they didn't even have time for nearly any reaction nor negative emotions, which was sole reason Killer Sans came there) and kills everything and everyone present (even if he didn't want to). In this stage only thing he will show is his scary face, and will say absolutely nothing until killing everybody present

Personality: insane demeanor, 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

appearance: he wears a blue jacket, black shorts with white stripes, a white shirt and instead of slippers, blue tennis shoes. His shirt also appears to be stained with blood

Personality: 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, his cold self on the outside to strangers, Cross has a soft spot for those who he cares on the inside

Appearance: He tied his bloodstained jacket to his belt and ripped his sleeves, tying the ripped cloth around his lower arms and sword hilts. Cross's shirt now has a sizable slash over his sternum (thank you Killer, awooga) and he no longer wears the, now cracked, locket around his neck: instead he tied it around the hilt of one of his swords

(Epic and Cross are very close to each other's that they do pranks on their siblings, jokes and have lots of fun together)

Personality: 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

Appearance: black and purple long-tailed trench coat that has a Half-Soul and white ribbon on its back. He wears black gloves that allow his skeletal fingers to show. For his bottoms, he wears black striped pants that are tucked into his boots

Personality: tendency to get too excited about things. He also has very short memory and will forget about different things - sometimes stopping mid-sentence to try and remember what he just said a few seconds before. He is very passionate about art and likes to motivate characters and creators

Appearance: black paint/ink on his right cheek. His eyes are usually a blue circle in the right eye socket and a star in the left. He dons a long-sleeved, white undershirt with a small brown jacket over it

(Ink loves to tease Error a lot even annoying him no matter what)

Personality: a hopeful soul that constantly radiates energy and joy. This is not because he is naive to what's around him, but because he chooses to see the bad and think on the bright side anyways. He is a constant source of emotional support and is often known as the heart of Snowdin

Appearance: gray shirt over-covered by a dark grayish one, dark pants, blue eyes, blue gloves, blue boots, and a scarf that comes out as a cape

Personality: very laid-back, sleeping on the job as often as he takes breaks. He enjoys making bad puns relating to skeletons, to the annoyance of his brother. He is kind and reassuring, but becomes eerily serious at abrupt moments (particularly when angry.)

Appearance: blue jacket, a pair of shorts, a white T-shirt, and a pair of pink slipper, which he calls "his special attack" to hit or throw it at his siblings

personality: 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

appearance: sharp teeth, with one being gold. His right eye is seen to be glowing red 24/7. He wears a black winter jacket with a jacket fur flame hood and a gray cotton hoodie, and a red sweater with a golden chain with black pants that have yellow stripes going down. He wears red shoes with yellow socks

personality: he judges the player very harshly. Sans also likes puns and tells them so much to the point that it annoys his older brothers. Outer is also sometimes depicted as a bit shy, supporting, caring personality

appearance: wears a yellow jacket with blue stripes on it. it also has some cotton on the edges of the hoodie. He wears blue trousers and pink slippers

is basically the adoptive parent of the Sanses
