Sans Fell is one of the major antagonists of Underfell AU. He is the brother of Papyrus and takes on an appearance similar to the Sans of Undertale. Sans is a skeleton, probably born in Snowdin, who is pushed around by his younger (though significantly larger and more durable) brother Papyrus, to the point of being forced to call him "boss." He is verbally and sometimes physically abused by Papyrus, and is forced to obey his brother's orders. Some differences about Underfell Sans is that his eye is illuminated in red, which is evil, and that he is destructive.
Sans works for his brother all the time. He is hated by everyone in Snowdin because he is the brother of Papyrus, though he tends to spend his time there anyway, at Grillby's. He has had to watch Papyrus kill innocent monsters nearly every day. At first, he hated the attitude everyone had towards him, but after a while, he stopped caring. He was not previously as mean-spirited as he is now, but since Papyrus became a member of the Royal Guard, Papyrus has been abusing Sans's power and using it mostly for his own cruel, selfish desires.
Sans Fell hates humanity because they sent the monsters to the Underground, and because of this, he just wants the whole of humanity to perish. While he respects his brother as his master, he secretly wishes they could at least be more brotherly.
Appearance
Underfell Sans looks very similar to his Undertale counterpart. He is a skeleton with sharp teeth, with one being gold. His left eye is seen to be glowing red almost constantly, and he has bags under his eye sockets. He wears a black winter jacket with a fur hood and a gray cotton hoodie, and a red sweater with black pants that have yellow stripes going down. He wears black shoes with red socks or even red slippers. Sans wears a black jacket, with the "fluff" at the collar being notably more ruffled than the original Sans'. His shirt is a red color in contrast to the normal white shirt. His shorts have a yellow strip instead of a white one and he wears black/red/white shoes or red slippers, as opposed to his counterpart's light blue slippers. His body structure appears the same as his counterpart (besides his Teeth )
Personality
He is aggressive with others and quite hateful when seen in Snowdin. This is shown especially when he is around the player. He often teases the player which usually results in Flowey getting very annoyed. The only time he is ever really seen to be hurt is when his brother takes credit for something he has done as he doesn't try very often and feels sad that he can't be acknowledged for what he has done. He is portrayed as sweaty, possibly due to emotional stress or strain, though it might also be a result of his frequent magic usage. He is mentally unstable due to the abuse his brother gives him and does frequently have nightmares, but he doesn't feel like he can tell anyone because he'll get labeled as weak. He is typically ruthless and brutal. His knowledge of the timelines and resets is shared among all AU's (excluding some interpretations of Underswap ) but he hides this information very well. He is not as "evil" as most of the other characters are portrayed, but still believes in the "Kill or Be Killed" motto. Mustard is his favorite food, rather than ketchup. The monsters in Snowdin hate him because he is Papyrus' brother and so they want him dead. He is portrayed to not care but deep down he's always terrified as he knows how easily most could kill him.
Abilities
Sans is a little more powerful than his Undertale counterpart. He can manipulate sharp bones and telekinetically move a living soul at ease. He can also manipulate Gaster Blasters, and is sometimes shown to be able to manipulate gravity and can recall each timeline that Frisk resets and saves.
