Sans is a newcomer to the Super Smash Bros. series. He comes from UNDERTALE, and most of his attacks are based around his final boss fight in the *spoilers* Genocide route. He was chosen for the game due to the upcoming release of UNDERTALE EX (UNDERTALE: REMASTERED EDITION in Europe). In fact, Sans's ultimate form, ULTRA SANS, is a Final Smash.

Sans is "similar" to Mr. Game & Watch and NES Mario, as he is completely flat and keeps his original appearence in this game (in this case, his battle sprite). He, similarly to Mewtwo, floats while walking and dashing. Since there are no sprites for the Sans boss fight, except for him standing, custom sprites were made. Something different, though, is the fact that he is not constantly looking at the screen, but is shown to be somehow sideways.

Sans wasn't announced at all before the game's release.

Victory Fanfare


Sans [after unlocking Sans]

(Sans's artwork) Sans is a skeleton and a main character in UNDERTALE. Near to the end of the game, he will judge you for your actions. If you've defeated every other monster in the Underground, including his brother Papyrus, he will rage at you with bones, Gaster Blaster, platforming madness, and psychokinesis. Most of his moveset is based around that. The number of Gaster Blasters that appear depends on how much the move is used, for example, with up to five Blasters appearing.


Sans (Alt.) [Classic]

(Sans using Boneshield)

Sans's Shortcut is a simple teleport, just like other characters such as Mewtwo or Zelda, but its distance can also be inputted. When shortcutting, Sans will be invisible and invincible. Levitate, on the other hand, makes Sans do a high-jump and levitate in the air, being able to attack and to go left or right. When using Bones, Sans will create a random pattern of bones around him, damaging opponents and protecting from projectiles and attacks. Does a similar thing with the Boneshield, but the pattern is always fixed, with the bone starting from Sans's back.

  • Shortcut - Up B Set X
  • Levitate - Up B Set Z
  • Bones - Side B Set X
  • Boneshield - Down B Set Z

Sans (Alt. 2) [Adventure]

(Sans psychokinetically holding Ness)

When using Psychokinesis, Sans will psychokinetically grab opponents right in front of him. He can then psychokinetically slam them to the ground multiple times before throwing them in any direction. Sans's Danger Zone makes him create a red-transparent circle around him. If the button is pressed again, anyone inside the circle will be launched away, but the circle isn't really big. When using Slam Dunk, Sans will grab the opponent, dribble them like a ball, then throws them away like if doing a slam dunk. This comes straight from basket.

  • Psychokinesis - Down B Set X
  • Danger Zone - Neutral B Set Z
  • Slam Dunk - Side B Set Z

Sans (Alt. 3) [All-Star]

(Sans using three Gaster Blasters)

The range and power of Sans's Smash Attacks is simply amazing. In his Side Smash, he uses psychokinesis to move a huge bone forward, like a fist. In his Up Smash, he does the same thing, but the bone rises from the ground. And in his Down Smash, the bone stomps right in front of him, just like it was a leg. When using the Gaster Blasters, the number of blasters used depends on how many times the move has been used: for example, 1 use = 1 bone. 5 uses = 5 bones. Since the max of blasters appearing is 5, 6=1, 10=5, 11=1, etc.

  • Side Smash
  • Up Smash
  • Down Smash
  • Gaster Blasters - Neutral B Set X

Sans (Alt. 4) [Master Orders]

(Sans sleeping at an hot dog stand)

In UNDERTALE, Sans sells hot dogs all over the place. In his Back Air, he throws one, dealing EXTREME knockback, literally! He can also put up to 29 hot dogs on his head with his Down Taunt. This isn't really much of use, but is still pretty exhilarating. His Forward Air makes Sans shoot three bones forward, like rockets. This is similar to Custom 2 for Bones, Rocket Bones. Another interesting Custom Move is Custom 2 for Shortcut, Shortcut Point. When the button is pressed the first time, Sans will create a "warp point" he can teleport to later by re-inputting the move.

  • Back Air
  • Down Taunt
  • Forward Air
  • Rocket Bones - Custom 2 Side B Set X
  • Shortcut Point - Custom 2 Up B Set X

Judgement [Crazy Orders]

(Sans using Judgement on Ness, Lucas and Ninten)

In UNDERTALE, near to Asgore's home, Sans will judge you for your actions. If running through a Genocide Route, he will take the human on battle. This Final Smash is pretty based on his attacks. Sans takes all opponents, and locks them into a Bullet Board then uses Gaster Blasters, bones, psychokinesis, and danger zones (also known as "Red Attacks"), and much much worse to avenge his brother Papyrus, and pretty much everyone else. After he seems he's done attacking, he summons an enourmous Gaster Blaster that finally launches foes away.

ULTRA SANS [Core Orders]

(ULTRA SANS shooting beams from its mouth and hands at Pikachu, Bowser Jr., Kirby, and Jigglypuff)

In the remake of UNDERTALE, UNDERTALE EX/REMASTERED, playing a Hard Genocide causes Sans to transform into ULTRA SANS after being defeated. 3 more phases will succeed: a phase that plays very similarly to Nightmare Flowey's battle, where you can only dodge attacks, a phase where Ultra Sans uses his powers to summon every other boss's SOUL to attack, and the last phase where Sans is fought as his huge head. In this game, he storms opponents with beams, fire, thunders, ice, psychic energy and stars.
