Background: Undertale is a 2015 2D role-playing video game created by American indie developer Toby Fox. The player controls a child who has fallen into the Underground: a large, secluded region under the surface of the Earth, separated by a magical barrier. The player meets various monsters during the journey back to the surface, although some monsters might engage the player in a fight. The combat system involves the player navigating through mini-bullet hell attacks by the opponent. They can opt to pacify or subdue monsters in order to spare them instead of killing them. These choices affect the game, with the dialogue, characters, and story changing based on outcomes.

• The Bad Sanses: The team consists of Killer, Dust and Horror. Their leader/king/boss is Nightmare.
• Enemies/The good guys: The enemies of the Bad Sanses, are the Star Sanses. The leader of the Star Sanses is Nightmare's brother Dream. The members of the Star Sanses are Ink, Swap/Blue and Dream.

CHARACTER: ERROR:

• Full name: Error Sans
• Nickname: Error
• Gender: Male
• Pronouns: He/Him
• Date of birth: April 4th
• Blush color: Dark blue
• Species: Skeleton
• Currently lives in: The Anti-Void
• Abilities: Error Blaster - He uses a type of Gaster Blaster called an Error Blaster, which are simply Gaster Blasters that are black in color and have blue tear-marks falling from their red eye sockets. Error's Gaster blaster is bigger, faster, and stronger than Classic Sans'. Blue Strings - He uses blue strings from his tear ducts to tie up and shatter SOULS, if his strings go inside a victim, he can transfer his soul into the victim's body, making his body vanish and the victim's soul to vanish turning the victim into him. This makes him able to control the victim, while the victim is helpless. This is Error's "main weapon" because Error feels more comfortable with the strings, as Error doesn't have very good eyesight. Glitch Hop - He can glitch himself and others into other AUs as the main means of Multiversal Transportation due to him being a error.

• Appearance: In the present, Error is a black glitchy skeleton with a color palette mainly consisting of dark reds/reds, dark blues/blues, yellows, oranges, and blacks. with his entire torso being black, while his legs are red. His metacarpals are black, while his proximal phalanges are red and his middle and distal phalanges are yellow. he has yellow teeth and two unsymmetrical eyes, with completely red scleras one a small yellow pupil and the other is a circle with yellow, blue and black. He usually needs to wear red round glasses because of his eyes being messed up from when he was Geno but refuses to wear them sometimes. his most signature feature was the light blue tear-like markings coming from his eyes to his chin. He wears a parka coat with pieces with blue gradients stitched together on the sleeves with yellow pockets. Underneath he wears a red shirt, which is possibly a sweater. He wears wide black pants, which are uneven and un-matching at the bottom with red stripes, the left has a blue gradient and is stitched together, the right appears to possibly be a cuff of blue stitched to the pants. He has a long blue scarf, and mismatched black sandals. Apparently, he steals clothes then sews them together to make his outfits. Being Highly Glitched, he has white "ERROR" worde all around him, with some minor glitching included.
• Phobias: haphephobia (the fear of being touched)
• First impression: crazy, deranged, goofy, mentally unstable
• Backstory: Error Sans was originally a variation of Classic Sans, but the human performed a genocide route. There are no real differences in terms of the original genocide route timeline until the battle with Error, where the human ends up winning. However, Error, after being slashed, rushed to Alphys' lab for some DETERMINATION extracted from a soul. Error injects himself with it, but the dosage was so large that Error trapped himself in the SAVE screen. Eventually, Error found a way out of the save screen, and began to play with his new-found DETERMINATION that he had gained. Despite warnings by the original Sans, Classic Sans, Error continued to experiment with his DETERMINATION, causing him to get stuck in the Anti-Void, where time is non-existent, and there is nothing but a endless stretch of white ground. After an unimaginably long time (which technically didn't pass at all, because time doesn't exist in the anti void) Sans went insane. For reasons unknown, Error' appearance changed, along with his power, and his memories were erased. Soon after going insane and changing appearance, Error learned to teleport out of the antivoid, where he found AUs. He was disgusted with them, and decided to destroy them, claiming they were mistakes and abominations. Now Error makes it his life mission to destroy AUs and even ATs (AT stands for alternate timeline, which is a slight variation from the main timelines).
• Personality: He has a selfish and sort of playful personality and thinks he's helping out the multiverse. He steals things, raids and destroys AUs, he loves to play jokes, and make snarky teases at his enemies. He doesn't get mad until things don't go his way, how he expected it to happen, or when others trigger one of his fears. And although he has a lot of hatred toward non-canon materials regarding Undertale, the ones that slightly deviate from the original annoys him the most. This makes him a literal man baby. He calls AU's abominations, including himself! (He calls himself abomination #1). But he seems to have somewhat of a bias towards the Classic Sans. He is also demented and has a very bad mental health issue, which can be classified as criminally insane. He believes himself to be a god of destruction (which he has rightfully earned). He often smiles a lot, he sometimes acts as if he's running on coffee. He's silly. He hates Fell Sans the most out of all the AU's (which is basically an edgy version of the original AU), Error often pranks him by stealing his stuff (mostly chocolate, or furniture).
• Trivia: One time, Nightmare (The king of negativity and the leader of the bad sanses) tried to recruit Error into his villainous team, but Error refused. Because he's just cool like that. (Nah, he just works alone.)

FELL SANS:

• Appearance: Fell is a short skeleton. He has a sweating skull, two eye sockets, with the left one having a glowing red eye bags under the eye sockets (due to lack of sleep), a nose, and a smiling mouth with sharp teeth and a yellow tooth on the left. He wears a black unzipped jacket with a white hood, red shirt, black basketball shorts with a yellow line of the side of them and red sneakers.
• Personality: Fell is shown to be okay with puns, but prefers knock knock jokes much more. He often gets tired, but not flustered. He strives to be collect and cool. He loves mustard and relish. He is also sarcastic.

CLASSIC SANS:

• Appearance: Sans appears as a relatively short and paunchy skeleton, with mitten-like hands. Sans is always seen with a wide, toothy-grin on his face. Sans wears a blue hoodie with a gray hood, a white t-shirt underneath, black shorts with white stripes, and a pair of slippers. He has white dots for pupils in his black eye sockets that disappear when he is serious or angered. When Sans uses telekinesis, his left eye flashes light blue and yellow (the colors for patience and justice) while his right pupil vanishes
• Personality: Sans is lazy, often sleeping on the job and taking breaks. His laziness is a combination of fatalism and apathy, as he is aware of timeline resets. Conversely, he suggests that this knowledge could be "a poor excuse for being lazy." He enjoys being mischievous. Sans primarily acts this way towards those he is in good terms with. Sans is also fond of making the occasional low-brow puns. He enjoys making others laugh in general, as he also performs at the MTT Resort as a comedian. Despite Sans being apathetic towards his own life, he is considerate to those he cares for. Although Sans hates making promises, he respects Toriel's request to watch out for any humans. Even if the protagonist killed people that were close to him, Sans refrains from broaching the topic until the Last Corridor. He is also observant. Though Sans is usually agreeable, he can become eerily serious to emphasize a subject. Sans may have a scientific background. Evidence includes the quantum physics book, his workshop, affinity for science, his inexplicable ability to teleport and his timeline research.
