Fell is a skeleton with sharp teeth, with one being gold. His right eye is seen to be glowing red 24/7. He wears a black winter jacket with a jacket fur flame hood and a gray cotton hoodie, and a red sweater with a golden chain with black pants that have yellow stripes going down. He wears red shoes with yellow socks.He doesn't like puns but likes knock knock jokes, he strives to be the cool brother, he loves mustard and relish. He isn't flustered and isn't always angry, he's just very tired.
