This is definitely one of the most stable fusions possible. Grillby and Sans are very close friends, know each other well, and see each other almost daily. The only problem with this is how incredibly different their personalities are.
Sans is kind of a mess, happy to jump into conversation, family oriented, has multiple part-time jobs, and an unpaid tab. Grillby is tidy, soft-spoken, work oriented, owns a successful business… and is the person Sans is supposed to pay.
So as a fusion, while they look quite interesting, they essentially even out each other’s personalities. They’re just… a pretty regular guy, personality wise. The fusion is just as happy to sneak a pun into conversation as they are to listen in silence. They’ll do any chores that need done without complaint, but they might take a nap after. They’ll cook a mean burger and drown it in ketchup.
Visually, they are a completely stable fusion: two eyes, two arms, nothing odd. They wear business casual (no surprise there) and appear to be a skeleton-shaped fire elemental. Proportionally, they look more like Grillby, but the fire that makes up their body doesn’t ever extend past their skeleton form. The fire is primarily red/orange, but their magic is Sans’s deep blue color.
The fusion’s favorite thing to do is run Grillby’s restaurant and it’s no surprise that patrons love them. Even though all the ketchup mysteriously disappears by the time their shift it up.
