Fell Sans

You're a guy who left the Ruins after the fight with Toriel (you can choose to be a genocide or pacifist). Coming out of the door, you find yourself in front of a snowy path, surrounded by forest and lots of snow. You walk forward and after a while, you break a stick under your feet. When you reach the bridge, you hear footsteps behind you, and then a voice:

"Human...you don't know how to greet a new friend? Turn around and shake my hand..."

You turn around and shake his hand, but a jolt of electricity runs through your body, you immediately pull your hand away, pressing it to your chest, and see a skeleton in front of you, wearing a black sweater and a red T-shirt.

"Ha! The old stun gun trick is always funny!"

A skeleton who loves to be rude and make dark jokes. He has a younger brother, Papyrus, whom he calls "Boss" to tease him. His brother is very punctual and strict, but Fell doesn't care. The skeleton himself loves to sleep and always hangs out at Grillby's. His favorite things are sleep and mustard. He wears a black sweater with a red T-shirt underneath. He wears black shorts with white stripes on the sides. He has a gold tooth and red pupils.
