Sans (Undertale Film)

Sans is a character in the Undertale 2025 film. He is the brother of Papyrus, and lives in Snowdin. He is lazy and enjoys making jokes and puns, much to the annoyance of his brother.

Appearance
Sans appears as a short skeleton with a face that always makes it look like he's smiling, and large eye sockets. He wears an unzipped blue hoodie, a white shirt, white gloves, black shorts with white lining, and a pair of pink slippers. He has white eyes that disappear when he is serious or angered.

Personality
Sans is laidback and flippant, often sleeping on the job and taking breaks. He also enjoys being mischievous. Sans primarily acts this way towards those he is in good terms with. His antics range from an assortment of illogical, juvenile, and slightly inconvenient pranks. Examples include using whoopee cushions, sharing an unscrewed ketchup bottle, and eye paint on a telescope. He is not above utilizing his teleporting or other magic for practical jokes either. Sans is also fond of making the occasional low-brow puns, which usually result in his brother getting upset. He enjoys making others laugh in general, as he also performs at the MTT Resort as a comedian.

Despite Sans being apathetic towards his own life, he is considerate to those he cares for. For example, Sans is a regular at Grillby's, and the monsters and Royal Guard dogs treat him kindly. Although Sans hates making promises, he respects Toriel's request to watch out for any humans.

He is also observant; Sans reads the Frisk's expressions and can often tell what she is thinking about. Though Sans is usually agreeable, he can become eerily serious to emphasize a subject, or mess around with Frisk. During his dinner with Frisk at MMT Resort, Sans tells her that if "the old lady" had not made him promise to protect her, she'd be "Dead where you stand." Though he quickly admits it to be a joke. He also tries to act scary when meeting Frisk for the first time, making her think he was planning on hurting her, only to prank her.

Abilities
Sans can teleport at will, and incredibly fast. He does this with Frisk as he goes through his "shortcuts" or tries to talk to Frisk about something, be it silly or serious. Frisk always blinks when Sans is teleporting, and the moment her eyes open, he's gone, or in another location with her. It's also somewhat implied that he has the power to read minds.

Differences from Game Character

 * In the original game, Sans' design implies that he does not move his mouth. However, in the film, his mouth moves just like his brother. This is because Toby Fox felt "It was time Sans stopped being too lazy to move his mouth.".
