Without ★ human

personality

Sans is shown to have a very relaxed personality, sleeping on the job or taking breaks frequently. He enjoys constantly making bad jokes involving skeletons, much to the displeasure of his brother, although he performs as a comedian at the MTT Resort, which suggests that he likely has talent with comedy. He is good-natured and comforting, but becomes sinisterly serious at abrupt moments (particularly when he appears angry). He is extremely observant, his language and actions change the most throughout the game depending on the choices made. He has knowledge of how many times he has defeated the player (on the Genocide Route). He tends to say that he hates making promises. His laziness appears to be, in fact, a mixture of apathy and fatalism. This is notable in the final battle of the Genocide Route. He's unsure if being aware of the resets has broken his spirit, knowing that everything he does will be worthless... or if he's just using it as an excuse to be lazy.

clothes

She wears a normal white t-shirt and a blue coat, along with that some black sweatpants, white socks and pink slippers.

skills

He has gained knowledge of multiple timelines and the function of SAVE through his seemingly scientific research, as seen in Sans' lab. He appears to have knowledge of when the player loads a SAVE file, though he cannot use the SAVE function himself. However, he does not seem to be able to remember what happened when performing a RESET, though he can recognize when the player has performed one. It appears that his situational awareness and innate perception allows him to recognize when a player has been behaving suspiciously. Likewise, he has shown the ability to move incredibly fast and/or teleport with the frequent use of "shortcuts" to get wherever he wants. During battle, he can fire what appear to be a type of beam using a weapon called the "Gaster Blaster" (the name given to the weapon's sprite in the game files). The Gaster Blasters whose name would mean Gaster's weapon or a weapon against Gaster bear similarities to the DT Extraction Machine found in the True Lab, Gyftrot's head, and the head of Asriel Dreemurr's final form. Sans also seems to know if the protagonist has gotten an impossible ending in a Neutral Route, calling him a "dirty hacker" in the corresponding phone call. This also counts as an error message, which happens very rarely. Sans also appears to know how to play the trombone, though he is only seen using it once. This occurs when he leaves his room and plays the instrument while examining the dishwasher drawer in the kitchen and discovering Irritating Dog, who was eating one of the bones Papyrus keeps there.

in battle

His stats in his genocidal battle are extremely low (having only 1 ATK and 1 DEF). However, his arsenal of skills is considerably high; being able to quickly change attacks just to confuse the player, or attack them even in the options menu. In addition, he does not give invincibility frames after a hit (this being a skill of the Purple Soul: KR, similar to the poison effect in other RPGs). His attacks are based on the use of bones (both normal and light blue bones) similar to Papyrus, the use of both the Blue Soul and the Red Soul to dodge certain types of attacks, his ability to change the player's "gravity" (using the Blue Soul at will), and the Gaster Blaster (a lightning attack launched using a goat or dragon skull). In addition to this, he uses his teleportation ability to combine attacks and can even attack with normal bones in the selection menu. These attacks are usually lethal and have difficult to dodge patterns; however, he is defeated with a single hit. To defeat him, a total of 25 hits must be made (counting the last two hits that are made in his "special attack"), with each hit the fight will progress and Sans will release a dialogue, if another command is used (ACT, ITEM, MERCY) the fight will not progress.

relations

Papyrus: Sans admires and cares for his brother. He reads Papyrus bedtime stories and helped him make his "battle suit" a few weeks before the events of Undertale. However, he likes to tease him by making bad jokes and pranks (which is typical of his behavior), which drives Papyrus crazy. Sans worries that other people will take advantage of his brother's innocence, thus assuming that "the flower that talks to him" must be a prank by someone using an Echo Flower. If the player kills Papyrus, Sans does not appear again until the Final Hall, where (in a Neutral Route) he will harshly judge the player for it. In several neutral endings (if Papyrus is forgiven or has been befriended), Sans is afraid to tell Papyrus about the other characters' deaths, so he prefers to lie to him by saying that they have gone on vacation. Toriel: Toriel and Sans are close friends, sharing a passion for bad jokes and puns. Sans never meets her in person, until the end of the True Pacifist Route, or in the neutral endings where Toriel was left alive, despite being someone who doesn't make promises. Toriel keeps a log of Sans' jokes in her journal (this can be found in her room). If the player reaches the end of the Genocide Route, Sans indirectly apologizes to Toriel, as he is forced to break his promise to stop the player's actions.

relationships 2

Flowey: Flowey attempted to experiment on Sans using his SAVE ability. However, Sans "has been the cause of more resets than he can count", implying that Sans has been the only thing capable of stopping him, much like the player in a Genocide Route. Sans doesn't seem to know much about Flowey, as he himself, when talking about the "Talking Flower" that appears to Papyrus, leaves it as an Echo Flower (although "Talking Flower" and "Echo Flower" come in two different colors). Flowey also calls Sans "Smiley Trashbag".[4] Smiley Trashbag".[4] Alphys: It is hinted that Sans and Alphys share some history. Just before they surface in a True Pacifist Route, Alphys jokes that all this time she has been fighting for the ability to watch anime on the internet, just like Sans. She jinxes him by saying that she knew he was going to make that joke. Papyrus then inquires into how they know each other. Alphys tries to stutter something out before Sans covers for her.

personal information

Fun facts

There are many clues that show that Sans may have had a scientific background; his work area, his dialogue in his boss fight on the Genocide Route, the quantum physics book in his house, the mysterious machine, Papyrus mentioning his passion for science fiction (especially if it's real), among others. If you enter Sans' room, his bed can be seen to be in poor condition for proper sleeping (with the bedspread rolled into a ball and his pillow thrown to the side without a cover), which could explain why he falls asleep at various points in the game. He also owns a treadmill which he uses to prank the player upon entering his room, though Papyrus claims that he is playing a prank on you across space-time. Sans has the ability to teleport, although it is also believed to be super speed. Sans loves drinking ketchup, as seen in his interaction with the player at Grillby's, where he does not eat his share of the food but will drink the entire bottle of ketchup if the player refuses it. Likewise, Sans will keep track of how many times he has managed to defeat you, and will become more mocking and defiant the more you lose to him. He stops counting after the eleventh time. Afterwards, he simply says "let's just get to the point.[9]" before the battle. Despite appearing to have a cheerful and playful personality, Sans is very serious and calculating as can be seen in several more serious parts in the game and outside of it. Sans, like the other main characters, has a defect, in his case being lazy.
