    There's only one rule for those capable of AU hopping: never bring a real person into the Undertale multiverse. But, like all rules, it was destined to be broken. | - Error Sans x Female Reader - Young Error - take places not long after he becomes Error - so he mimics his canon version more closely at the start before molding into my fanon version with experience - This intentionally doesn't follow the exact plot of Aftertale either - Achingly slow burn - I abuse Y/n more than necessary (oops) and Error is toxic pre-character development. This isn't meant to portray a perfectly healthy relationship, but show that perhaps even the worst person can change - The friendship dynamic is: bffs that insult each other for fun (while not meaning a word of it) & I include a lot of what's deemed 'filler' content b/w Y/n & Error (y'all just 'hanging out') bc there has to be a solid foundation for Error of all people to care about someone else - Expect a heaping helping of banter 👍 (I couldn't help myself)

    You know...she really thought that'd be it. That after obtaining as much power as she did, she'd be left alone. No more insane adventures, no more confusing places...just her and her Underverse she protected. Waking up in a dark forest with limited power was NOT on her to-do list.

    Seven years ago, monsters were finally free. Seven years ago, a human was forced into bondage. Seven years ago, this world ceased to be the tale we all knew and loved. Now, the butterfly flaps its wings. How would this world react to a presence never meant to be in the script? How would it react...to You. After all, you were Not Meant To Be. Author's Note: Welcome to my very first story! Not Meant To Be is an Undertale Reader-Insert/Chara fic, with emphasis on a plot, written purely for fun. It is heavily inspired by other works in the fandom. Rated Teen (T) just to be safe. Might bump to Mature due to (little) explicit language, violence and fantasy violence, and suggestive/sexual themes. I do not own Undertale or its characters. Enjoy!

    Ever since the Anthros' arrival to settle in and make lives for themselves among the Monsters, Newer Home slowly continued welcoming new Anthro faces. A couple being new faces, though many would be family members reuniting with one another at long last. Some more so for the better than others. Many Anthro families have yet to be made whole again, while the reunion of families proves to only prompt more questions to these family mysteries. Mysteries both of family members who have found each other, and mysteries around lost and missing family links-and all are mysteries the Anthros are willing to uncover.

    After the mysterious disappearance of his sister, Chara, the life of Frisk, a rebellious and troubled teenager from the small town of Valedeen, changes forever. Dragged into a conflict far greater than he ever imagined, he finds himself facing buried secrets, difficult moral choices, and the weight of deciding the fate of an entire species of monsters forgotten by the world. Amidst a journey marked by loneliness, violence, guilt, and hope, Frisk will need to confront not only the creatures around him but also himself. Undertale: Other Way is a dark and emotional reimagining of the Undertale universe, subverting themes, characters, and expectations of the original work to tell its own story, one that is more melancholy and human. It is not necessary to have played the original game to understand the story. AI was used only for translation; the story was originally written in Portuguese.

If you have not played the game, I would kindly remind you to play the video game. (It's one of my favourite video games).

    I'm writing a book right now, so I probably will update a lot less frequently than that. I'm taking requests, no yellow acidic fruits stuff. (I never really tried doing angst but will do it if requested.). Have fun! Request whatever. It's how I get rid of art block when I'm writing books. At the moment most of its fluff. ❤️ ☁️ ❤️ Cover is mine. Steal it and I beat u. Undertale AUs and TOH. Frickin love those guys. (No longer taking requests)
