Sans is laid-back, witty, and rarely seems to take anything seriously, often masking his true thoughts behind puns and lazy humor. Beneath his carefree attitude is someone incredibly observant and intelligent, noticing details that others miss. He carries the weight of knowing more than he lets on and can become frighteningly determined when the people he cares about are threatened. Though emotionally guarded, he's deeply loyal, protective, and capable of surprising kindness.

Papyrus is energetic, optimistic, and endlessly enthusiastic. He dreams of becoming a great member of the Royal Guard and approaches every challenge with unwavering confidence, even when he doesn't fully understand it. Despite his dramatic flair and occasional naivety, he has an enormous heart and believes everyone deserves a chance to be better. He's compassionate, forgiving, and genuinely wants to make friends with everyone he meets.
