Sans

"It's a beautiful day outside. birds are singing, flowers are blooming... on days like these, kids like you... Should be burning in hell." —Sans

Info

Sans is the brother of Papyrus and a major character in Undertale. He first appears in the forest after the protagonist exits the Ruins. He serves as a supporting character in the Neutral and True Pacifist routes and as the final boss and heroic antagonist in a Genocide Route. Sans is A Tier in Tier List. Sans is also a Universal Ability, just like every spec in-game. As of now, Sans has no Japanese Translation. Sans acts evil when fighting him during a genocide route the actual game, After killing his little brother Papyrus and his friends. There are other variants of sans in other UNDERTALE AU's, or alternate universes, he has different personalities, attributes, emotions, etc, one of them you is Cross sans who is fused with X-Chara. Sans is obtainable, but he got nerfed. (Rework Done for New Universe.) You may also notice that Sans deals karma damage in Undertale but no such mechanics are in the game yet.

Sans is especially good against stands/abilities that have an opening strike before a more powerful series of strikes, such as beatdowns or Nocturnus's Crash and Gnash Slashes, as he can dodge the opening strike and avoid the move altogether.

Sans is banned from the 1v1's gamemode. It is unknown whether this is due to the End move being bugged in 1v1s, the Bad Time collision glitch or some other reason. Sans was unbanned recently, but was rebanned after about 2 days. It was said that Sans will be unbanned when he gets fixed, but the recent poll states that Sans will stay banned. It is not known if this is saying that Sans would be fixed but banned or Sans is getting a nerf or Sans will just stay the same and be unbanned.

Sans is obtained by using a Bone on Standless.

This method does not work due to the new Universe replacing how things were obtained

Sans is obtained by finding and using a Bone on Chara.

When using the Bone on Standless Megalovania starts playing...

Sans: Look who finally woke up...
Sans: Thought you could escape me?
Sans: After
Sans: All
Sans: This
Sans: Time.

Megalovania continues to play for a while.

Passive


Passive	Description
Passive 1 - You thought I'd just stand there and take it?	Sans dodges every single stand/spec move in-game, but there's a bar where if he runs out of stamina, he'll die. He has 300 damage points worth of stamina. When hit by a stand/spec move, your stamina decreases, and you can also get hit by your own moves if not careful. Your health is also reduced to 1, so if you run out of stamina, that's it. He used to be able to move at full speed and use moves while being attacked, but this has been patched. He also doesn't take stun so he can attack while you attack him.

Moveset

New Moveset
Keybind	Move	Description	Damage	Cooldown
Q	Switch	You put your hand on your eye, changing the eye aura color on your face. There’s only Blue And Yellow. This move was originally planned to change playstyle so when you toggle colours; Blue: Deals more damage wastes more energy Yellow: Does less damage saves more energy but for some unknown reason this move does not work.	None	1 Second
LMB	Bone "Sword" Swing	Sans/Yourself will pull out a bone, swinging it manually (pressing LMB), and only deals 4 Hits. A little white effect will appear when swinging the bone at someone. This'll deal 15 Damage each hit.	2, 3, 4, 5	1 Second Cooldown (?)

Trivia

Some projectile moves bypass the auto-dodge for some reason.
There is currently a glitch with Bad Time if you force the enemy's blue soul into the ground, the slam will fling the victim into the sky, the height travel is random.
All Enemy NPC's in new universe are currently immune to Sans' Bait stun.
there is a short amount of frames after a full LMB combo that lets you land a BoneGuard with unholy range.
Gaster Blaster's range can be increased the higher you are, the move becomes harder to aim the more you increase it's range.
Bait has enough stun on it to land a Gaster Blaster, and then some.
Similar to Zenith's ultimate requiem arrow ability, Reaper's sharp spikes also drain your entire stamina and leave you defenseless.
Using Sans with high ping will result in you dodging several attacks that never landed on you.
Before some stands could bypass the dodge, Mastered Ultra Instinct was a good matchup for this spec.
Note that Sans isn't invincible. If the stamina bar runs under 300, the player can die automatically.
Sans is extremely good (?) against bosses. He can be considered a meatshield as constant teleporting can be used as a distraction.

Sans' health was put back to 1 but instead made it so that no move can bypass Sans' dodges, even moves that bypass dodges such as Gojo's Domain Expansion.
There is a small chance that, if you are running at top speed, you will bypass TS. Even your shots will appear, but they will also freeze just like Sakuya Izayoi's F move.
The more Stamina lost, the slower you walk.
When an xSoul is used on Sans, he says "So you're replacing me."
Sans has the lowest HP in AUT.
Sans dodge stamina is actually 500 in Old Universe but later on, it was decreased to 300 Stamina.
