Royaltale Season 1
This is an Undertale AU I originally planned on making back in 2019 but, I wasn't capable of making all the character designs and forgot about it for two years. A few months ago, I thought about redrawing the only two designs and reviving it as well as changing most of the original plot and instead of making a comic series, I'm writing it so it will be easier to think about more designs. OCs are included in this AU. If you would like yours to make an appearance, message, or tag me to discuss when they can appear. This is season 1 of the series and it will basically follow the events of Undertale because there was a strange, unexpected reset after 10 years of living on the surface. Now, it's up to Frisk to help her friends remember their lives before the reset and save the world before Flowey tries to kill all of humanity as well as monsterkind and Mystickind. Can the determined human survive yet another perilous journey through the Underground or will everyone fall to Flowey's hands (leaves?)?
What Is Love?
For many years, Frisk never once knew about Valentine's Day. What?!! That's probably what you're thinking. Anyways, Frisk has a huge crush on a certain skeleton who's also crushing on someone else. Will she be able to confess her love to him and live a happy ending? Also...Frisk is a girl in this story ;) UNDERTALE DOESN'T BELONG TO ME. IT BELONGS TO TOBY FOX. None of the used pictures&gif's are mine. And that's about it. Plz follow, vote, and comment in my books. I'll be happy to hear from you. Buh bye!!!!

Undertale React
Undertale is going to react. This will not be entirely canon and will include aspects of what I believe (backstories, ect.) I do not own the cover and I do not own any of the characters.

Undertale - Fight For Your Future [Frans] [Book 1]
It's not easy to not be haunted by things in the past. Especially when those things from the past just won't stop coming back. They won't stop coming back, and they won't stop trying to steal your future. Not unless you try to fight for it. So, this is a Frisk x Sans story that I had originally written over on Deviantart. But I also wanted to upload what I wrote here for those of you who don't actually know me on Deviantart! So I hope you guys do enjoy what I have written! ^-^

Undertale; Despair AU 《REWRITE》
What if there was an anomaly in the Underground? No, not Frisk. Not Chara either. Someone else entirely. How could a few measly children stand to this supposedly immortal foe and save the Underground from destruction? Is it even possible to do so? Only one way to tell... ~o0o~ Disclaimers before you start! •There is NO fanon ships. That means no Soriel, Papyton, etc. The only ships are Torgore (in the past) and Alphyne. •This is NOT an x reader. I dislike those types of stories. The reader will have no part in this, and they will not be shipped with anyone. •This exists outside of canon to an extreme. For example, Frisk is the second human and not the eighth. •There will be OCs, but only for a few humans and they still technically exist in normal Undertale. •There is a sequel. I'm planning on rewriting it after this one, as it is much more random and definitely needs it. Clanky, plot holes/retconning, etc. It's more of an OC thing, to explore them and their issues, than an Undertale thing, but it has its similarities. •There will be some explicitives. It won't be unnecessary or excessive, only when it fits the situation and character. I will not be using any slurs, as that's just plain disrespectful, even if some of them apply to me. Credits: Undertale, obviously, created by Toby Fox and Temmie Chang. "The Time Before" by ANinnyMouse42 is the backstory for Sans in this AU with some adjustments (mainly since that was very close to my original idea before I read it and I don't want people to think I copied their masterpiece or smth, if you haven't read it please do so, it's really good). Some things will be in reference to the other books in the trilogy or "From War to Science" by Emotistic-optimistic. If you haven't, read that too. It's really good (along with its sequel). The cover was made by me! Have a good day! (Also, the title is a placeholder, if anyone has any ideas that make more sense, please let me know.)

What Went Wrong?
~'Disclaimer: This story has a lot of profanity and covers some very very intense or touchy subjects that may disturb some readers. You have been warned.'~ ((Unedited)) After Chara fell into the Underground, they met Asriel a monster inhabitant of the Underground. Soon after that, Chara joins a new family, but their ambition to keep everyone happy goes a little overboard and Chara is flung into a reality of destruction and hopeless wonder. Then many long years later they meet the beloved Frisk, who fell into the Underground, similar to themselves. Eventually everything Chara thought they knew correctly is turned upside down and they as a person are changed forever. ~'The game Undertale belongs to Toby Fox and some of the dialogue is ripped straight from the game itself, too.'~

Reset (Sans x Older!Frisk)
There are some things you just can't take back. No matter how many times you reset. After breaking free of Chara's grip, Frisk decides to do one final reset before defeating Sans or proceeding to the throne room. But some memories last longer than others, and broken trust isn't easy to repair. Female, aged-up Frisk. Starts out canon and then diverges. Eventual Sans x Frisk. Undertale was created by Toby Fox. I do not own Undertale, nor any of the characters. Some violent action scenes. Cover art is by amazing artists at http://www.zerochan.net/Undertale,Fanart and http://www.zerochan.net/Chara+(Undertale),Fanart

Plumetale-Broken Wings
Part 2 to Plumetale. Or should I say. Another run. Due to Frisk being Soul Poisoned. A purified Chara resets the world to avoid Frisks permanent death. Unfortunately, the only ones who know about the reset are Sans, The River Person and The Man Who Speaks With Hands. Frisk can't remember much from their previous pacifist run except for the love of her friends. Will they be able to save them? (Still a placeholder cover, lmao)

Love can't tear us apart... Right?[On Hold]
(cover draw by me. It's just a version from an inspiration I saw from another artist that I forgot their name by the way-) read this story if you like a Canon character being ship by my persona. I mean for me it's better than doing an x reader XD I'm so bad at those(I don't even understand how people loved my Huggy wuggy one-). anyway enjoy. Gaster belong to Toby fox. the other characters from Undertale has well. only my ocs and persona belong to me. So has the drawing you will see in it. if I even remember to put some in ^^"

Sans X Reader // You're Too Punny
Smol thing I guess. I don't own Undertale (obviously), but I do own all of the art in this book (as the first A/N states). This is my first fic. I update as often as I can, especially on most weekends. Don't be afraid to comment if you have something to say.

Forbidden Love ( Frisk x Sans)
Hi guys this is a new story based off of the game undertale. Also this is my first fanfic I have ever written so I hope you like it. Frisk is 13 and so is chara. Sans is 130 which basically means he's 13 in monster years. Papyrus is 160 and toriel is 170 aka 17. Undyne is also 170. Mettaton is a girl. Alphys is 160.

The True Timeline
If you haven't read the other one, that's okay! This is mainly to fix timeline problems and mistakes on my part that don't make sense!
Runaway
Finally. They made it to the surface. But after an attack on the monster king, Undyne reveals a hidden secret that destroys the group. Can they bring themselves back together, or will their friendship break even more. (I suck at writing descriptions [~_~] )

Soldier Boy (An Undertale Story)
What if Asgore knew that Sans was a weapon built by the scientist before Alphys? What if Frisk couldn't fix the gap between humans and monsters? What does Protocol Soldier Boy mean to them? Plenty of cursing and some violence. That's really all my stories ever are.
