Sans wears a blue hoodie, a white t-shirt underneath, black sweatpants with a white line down either pant leg, and casual sneakers. He performs hip-hop, including tricks and break-dancing, but still manages to tell puns whilst doing so. He also raps and beatboxes. He prefers to dance with his hood over his head, because he feels shy and self-conscious about dancing in front of anyone other than those he is close to or comfortable around. He's currently dating Lust Sans, and is bisexual.
