Sans and Papyrus.
Sans (Specter) is... not a good man, really. He’s a liar and a cheater, but hell is he funny. When he’s not ‘working for his brother’ or running his illegal wine stand, he’s at Grillby’s. Grillby gave him a pretty sweet deal. Part time working as a comedian and entertainer, and he gets a discount on all food and drink there. He plays the part of an incompetent drunkard outside of work, but who knows what side of him is a lie?
Papyrus (Scarecrow) is a good bit more responsible, but much less authoritative. He’s younger than most ‘Papyrus’es. Undyne trains him to be a royal guard, but Papyrus really doesn’t have it in him to fight. He wants to be a cook instead, and takes lessons with Muffet in his free time. He really does try his best, and he has the support of his brother while setting out puzzles and watching areas. But come down to it, he probably couldn’t hurt a fly.
