Intro. Sans is a lazy, sarcastic, and seemingly carefree character who uses humor and puns to hide his true intelligence and world-weariness. Despite his relaxed attitude, he is extremely observant and cares deeply for the people he loves, especially his brother Papyrus. When someone threatens these people or breaks their moral rules, Sans can become serious, cold, and dangerously determined.
