course, that doesn't mean you're completely innocent or naive. just that you kept a certain tenderness in your heart. no matter the struggles or hardships you faced... you strived to do the right thing. you refused to hurt anyone. even when you ran away, you did it with a smile. you never gained LOVE, but you gained love. does that make sense? maybe not. you're about to face the greatest challenge of your entire journey. your actions here... will determine the fate of the entire world. if you refuse to fight... asgore will take your soul and destroy humanity. but if you kill asgore and go home... monsters will remain trapped underground. what will you do? well, if i were you, i would have thrown in the towel by now. but you didn't get this far by giving up, did you? that's right. you have something called "determination." so as long as you hold on... so as long as you do what's in your heart... i believe you can do the right thing. alright. we're all counting on you, kid. good luck.

you can't understand how this feels. knowing that one day, without any warning... it's all going to be reset. look. i gave up trying to go back a long time ago. and getting to the surface doesn't really appeal anymore, either. cause even if we do... we'll just end up right back here, without any memory of it, right? to be blunt... it makes it kind of hard to give it my all. ...or is that just a poor excuse for being lazy...? hell if i know. all i know is... seeing what comes next... i can't afford not to care anymore.

Sans is the older brother of Papyrus. He is a extremely lazy skeleton with a love for bad puns, jokes, pranks, junk food like Grillby's, quantum physics and science fiction (especially when it's real). Everyday Sans also reads bedtime storys for his little bro, as well as go to the RUINS door to pratice knock-knock jokes with Toriel, where he accepted her promise to protect any humans that shall fall into the underground even without knowing her name, just because she shared his love for bad puns. He also seems to have worked with Alphys before, with him knowing about her amalgamates and she calling him a good friend in one of the endings. Sans is a very easygoing person thus being a very popular individual, but he hates making promises out of fear of breaking them. Sans might try his best into avoiding any type of work but he will give anyone who faces him a hell of a bad time.

Attack Potency: Wall level (Is stronger than a low determination Frisk, who tanked Undyne's house exploding), can bypass conventional durability with his attacks.

Speed: At least FTL (Should be the fastest non god tier character in the verse, capable of dodging Chara's attacks even while asleep, even with them knowing exactly where he would dodge them. Should be faster than Napstablook, who was able to close their blinds before the light reached them).

Lifting Strength: Unknown physically, Class 25 with Blue Mode (Should be comparable to Papyrus, who trains with Undyne on a regular basis which means he must have used his blue attack on her, implied to be already familiar with Undyne's own soul mode as well reinforcing this idea, Undyne is capable of suplexing huge boulders).

Striking Strength: Wall Class.

Durability: Wall level (His DEF is the same as his ATK, superior to low determination Frisk, who tanked Undyne's house exploding).

Stamina: Above Average (He is capable of fighting Chara for awhile before getting tired).

Range: Standard melee range, at least tens of meters with his magic, higher with Gaster Blasters, tens of kilometers with teleportation.

Standard Equipment: Hot Dogs...? and a Hot Cat.

Intelligence: Extraordinary Genius (Sans is shown multiple times to have an extreme knowledge of science and physics, normally reading quantum physics books in his off time, Papyrus also states that Sans loves science and that he studies astronomy. He has multiple blueprints of various inventions on his workshop, as well as a possible time machine, the workshop showns that he probaly was scientist or even an assistant to the previous Royal Scientist. He is shown to run reports of multiple different timelines, fighting out about the anomaly that SAVE and LOAD was doing to space and time. Implied to have built the dimensional boxes across the underground, due to being named "obj_sansbox" in the game's code).

Standard Tactics: Sans starts off by observing his opponent body language to determine how they act and what they are thinking, then using his info analysis and clairvoyance to know what his opponent was doing before fighting him and what their stats are, in order to ajust his combat style depending on what information he got, such as when he purposely fought in the most frustating way he could think of in order to convince the fallen child to give up since he knew he couldn't kill them permanently. When entering combat Sans will start off with his strongest attack (a combination of his blue attack, bones right afterwards and a couple Gaster Blasters in different patterns, all dealing KARMA) to kill his opponent without them being capable of reacting in time and thus ending the fight quickly, afterwards he continues using all his magic in different combinations to beat his opponent, while dodging his enemy attacks in any way he can using his instinctive reactions and other abilities, such as his teleportation, if he feels necessary. Sans does not follow a honor code and will do everything in his power to beat his opponent, such as cutting himself off to attack someone when they aren't expecting, attacking on someone's turn, tricking someone to lower their guard in order to backstab them, and even doing absolutely nothing.

Weaknesses: Sans is extremely lazy, thus making it harder for him to give his all due to the fear of everything being reset. All monsters are weak to extreme killing intent from a powerful soul (like Chara), therefore the crueller the intentions of their enemies, the more their attacks will hurt them, and a monster defense will weaken if they don't want to fight.

Notable Attacks/Techniques:

  • Soul Manipulation: Blue Mode: Similar to his brother, Sans turns his opponent's soul blue, giving it "gravity" and allowing him to more easily hit his foes. However, Sans appears to have a far greater mastery of this ability than Papyrus, allowing him to effortlessly fling his foe around by manipulating their soul, or effectively "changing gravity" and forcing them to move along the walls or ceiling.
  • Bone Attacks: Sans will send a massive amount of bones at his opponent, forcing them to think on their feet to dodge all of them. He will mix up his style, forcing his foes to jump through small gaps between bones, over pits full of dozens of bones, or even to rush along the platforms so that they don't fall into a deadly trap composed of dozens upon dozens of bones. Sans will often throw in blue bones, which while they have far greater range than the regular bones, they will only hurt his opponent if they attempt to move through them as opposed to allowing it to pass harmlessly through. While these attacks hardly seem to do any damage initially, the damage quickly racks up from remaining in contact with them, allowing this relatively weak opponent a way of bypassing the defenses of superior foes.
  • Gaster Blasters: Sans's strongest attack, they are strange devices in the shape of skulls which fire powerful lasers from their maws. Like Sans' bones, Gaster Blasters will often be used in numbers and will deal KR damage.
  • Teleportation: While Sans is unable to reset the universe in the manner of someone such as Frisk or Flowey, he has shown to have a useful form of teleportation, allowing him to teleport not only himself but objects and other people, as well. During a battle, Sans will often teleport his opponent, himself, and his attacks, not only moving out of harm's way but moving his foe into the path of a new attack. He has also shown the ability to restrain an enemy by repeatedly warping them back to their initial position.
  • Special Attack: Sans's has his turn forever, and thus his opponent cannot harm him during it. Sans usually leaves this as his final attack in case nothing else works, and so he is already very tired when the "attack" is used.
