Fell sans or Red, runs away to underswap so his brother won't hurt him anymore but what if Swap papyrus finds him and now fell papyrus is on a hunt for Red and will not stop.

An underfell story about one night sans woke up from a nightmare and ran into the woods not wanting to come back. it was very snowy and he almost froze to death till his brother found his unconscious body

Sans has a good life. A caring father, an adorable baby brother. Things couldn't have looked better. But soon after the two started school in snowdin with the other monsters instead of being home schooled, disaster strikes. Will Sans be able to get through this newfound relization unscathed? This story goes by the theory that gaster is the father of papyrus and sans. Though the theory is incomplete since no one knows who the mother is. For all we know sans and papyrus could have been made in Gaster ' s lab since they just "appeared one day" No one really knows, but it's fun to debate about. Enjoy

Sans (Red) is a monster trapped in the nightmare that is Underfell. Brotherly abuse and the stresses of this world cause him to do the unthinkable, how will the Swap brothers react to the arrival of his broken mind? Possible trigger warnings? I don't know, read at your own risk. UnderFell and by extension Undertale doesn't belong to me. Go check Toby Fox's game on Steam for the original Undertale story! Criticism is encouraged!

Red is a 16 year old boy still stuck in his freshman year of high school, it's hard to do your homework when your younger brother is constantly abusing you. Stretch is a 17 year old

With the resets jumping back and forth, it seems to simply set the same path once more. However, this pattern breaks when the code seems to restart - and this time, there are a few more unfamiliar changes. How will Red react to the new MERCY filled Papyrus? And how will Honey adapt to the brother he loved continuously flinching away? Updates every Sunday!

Sans is getting abused by his younger brother, Papyrus. That's all I have to say.

Non of the characters belong to me nor does the cover. Underfell was created by Kaitogirl Underswap was created by Popcorn Pr1nce So this is obviously a under swap papyrus x Underfell sans if you don't like fontcest then why are you here? Sans yet again got a beating from his brother. This time leaving another crack, physically and mentally. Sans was tired of it. If he wasn't needed he'll just go and let someone else be his brother's toy. On that night he left for better or worse and ended up in underswap going through a portal left behind by either error or ink sans in search of a new universe. Warning* Swearing, blood.

Sans is getting tired of his brother making him miserable. Being taunted and being bruised. He works on his machine a lot more now then simply disappeared. Where did he go?
