Fan Casting Sans in Undertale (2025)

Sans is a skeleton who serves as a supporting character through the film. Sans is laidback and flippant, often sleeping on the job and taking breaks. He also enjoys cracking jokes at opportune moments, much to the annoyance of others, such as his brother Papyrus. Though Sans is usually agreeable, he can become eerily serious to emphasize a subject, and when he does, he talks as if he's seconds away from murdering someone. The actor must emphasize Sans' comedic and lazy nature, with a voice that sounds awfully similar to that of Patrick Star's. But when Sans becomes serious, their voice must sound dark and creepy to reflect Sans' nature.
