WARNING: STORY HAS VIOLENCE (Y/N) is a young 17 year old who goes to Underhigh, the biggest high in the multiverse. (Y/N) had no friends and a bad past. She's smart though. She's tutoring three of the most popular monsters in school. Sans, Red and Rus weren't her biggest fans, Error and Nightmare were her biggest bullies. How will people change as they get to know her better? Will (Y/N) get to have people see how she really is? How badly will she get hurt before things change? Can she ever have true friends? Well dear readers you'll have to read to find out.

You're an emotionless yet guarded person. You rarely trust anyone much less let them get to know you. But, will a few skeletons who appeared be able to break your shell and help you heal? Rank #1: Undertale (Somehow) Rank #2: Undertale (Again, somehow) Rank #3: Undertale (Down we go) (Is being Rewritten/Edited because Author can't take it anymore) Note: I do not own Undertale, AU sanses or RedBull. (I have ownership over Exco as it is not a character based off any game, movie, Ect.) Undertale belongs to Toby Fox. The fan created characters belong to the creators. Your character belongs to you. Extra note: Let it be known that I will be editing the chapters as they are not the final result. They are simply place holders for people to read.

They were hurt. They never really felt love and care. What happens to them when their old abusive owner decides to abandon them in a cold night, when (Y/N) finds them? Their life will surely change! ~~~ Bitties are rare and expensive companions. You wouldn't call them "pets" like other idiots or spoiled kids would. They acted pretty human after all, and just beacause of their small size they are treated as so. You hated the people outside. Too much fakes, moqueries, judgements for you to handle, but you loved going out. The only problem is the noise other makes. You hated it. One night when you couldn't sleep, you decided to go outside in the park and finds something interesting... ~~~ AYAYAY First fanfic pleeeease not too harsh criticism TwT there's probably a lot of spelling errors, since English isn't my mother language. Welp... Tell me what you think! ~~~ AUs that're going to be in the story (Sans + some Papyrus cuz what are Sanses without their bro?) You won't find them all at the same time: Classic/Original! Sans and Papyrus Fell! Sans and Papyrus (Sans as Red, Paps as Edgy) Swap! Sans and Payrus (Sans as Blue, Paps as Carrot) FellSwap! Sans and Papyrus (Sans as Blackberry, Paps as ???) Ink! Sans Error! Sans Dream! Sans Nightmare! Sans Killer! Sans Horror! Sans and Papyrus (Sans as Horror, Paps as Bloody) (I just called Paps that eheh) Cross! Sans Dust! Sans Outer! Sans and Papyrus (Sans as Comet, Paps as Star) Fresh! Sans Geno! Sans weLP that alota biTTieS herE ) #6 in underswap! #4 in underswap! (what is happening) #8 in Bittybones!

Frisk spared everyone. The barrier was broken. All the monsters are free. But you, an 12 year old girl on a hiking trip, fall down. Now that the barrier is broken, no one should be left in the Underground, right? This is my first story, so it might not be too good... still, I hope you like it! Cover made by @Fluffy-Bush
