"i'm sans. sans the skeleton."
– Sans

Sans is the brother of Papyrus and a major character in Undertale. He first appears in the forest before Snowdin.

Profile Edit

A lazy skeleton who loves puns. He is occasionally shown drinking ketchup, and has a very strong connection with his brother Papyrus. Sans is a sentry.

Personality Edit

Sans is generally lazy despite having 3 sentry positions and running the hotdog stand, though fans have speculated this may be a cover. He has a liking for puns and knock-knock jokes.

On the Genocide Run, Sans becomes serious, threatening and fighting the player. This is the only possible way to fight sans and it is widely considered the hardest fight in the game

Powers and Abilities Edit

He's statistically the weakest monster due to having only one attack, defense and HP. Despite this, he is easily the most difficult fight in the game. mainly due to the ability to dodge every attack. He can not be physically beaten, he can only be outlasted.

He has powerful telekinesis, control over bones that can drain a person's HP depending on how many Execution Points they've obtained (Karmic Retribution) (EXP for short.) Sans can summon 'Gaster Blasters', skulls that somewhat resemble the DT Extraction machine in the true lab and one of Asriel's attacks, (in the true pacifist mode) and shoot beams of light that inflict KR (instant damage). Many of these can be summoned at once. He can also summon bones to attack the player's SOUL as they navigate the battle menu.

Sans is the only monster in the game who can dodge of his own accord, instead of you missing your blows. He dodges regardless of the power of your strike.

Weaknesses Edit

Sans has one attack and one defense. His attacks are very weak.

He tires out during the duration of your battle, eventually falling asleep - where you can kill him to end the fight. there is no way to spare him, or get around him.
