    I created the cover( Yes I know my drawing sucks its why i made it a story and not a comic) So as I said before this is actually a re-edited story and I decided to go ahead and change the description as well this is no longer an X reader story this is a pure fanfiction Our main character once went by Alex now turned into Kris from Deltarune, now he has to deal with the possibilities and dangers of the game is so fond of in real life. but now the dangers lurk even further then before because of his unusual presence, I wonder what will happen ( any and all pictures that I have created will be credited inside the chapters itself, any other pictures will be credited to their creators. Please do not reuse my arts/Drawings you are welcome to do a fan arts but not using my pictures) Inspired by @KarmaAkabane425

    (This is my second attempt at a remake So please enjoy this as I'm going to put much more description than the original) All characters involved are mostly out of character from their original counterparts. {This remake will bring new episodes, remade episodes, episode changes, spelling corrections, lots of editing, more pictures, more videos and new personalities from characters} (There Will also be more crossovers than before along with mentions of some of the My Little Pony creepypastas) Can even the most broken person be put back together. In This Au of MLP we will find out for ourselves. Y/n: I can't believe I did all of this to the underground.... Is it possible for me to truly change? Dusttale x My little pony friendship is magic WD GASTER: Things will be very different, this is for you to find out dear reader. This au is a very twisted version of the original My Little pony show. None of the pictures are mine all credit goes to their respective creators MLP:FIM is made by Hasbro.

    What is Ink was reborn? This is a fan fiction both inspired by the story "reincarnated Error" on Wattpad and "If Blue joined the bad sanses" on YouTube. The reincarnation part was inspired by Reincarnated Error, but the version of Ink I will be using and the backstory I'm going off of is from the story if blue joins the bad sanses. I am not at all a good writer and my autocorrect does shit without my consent so sorry if this sucks, I greatly appreciate if you correct me on some things. (no art is mine unless said otherwise. The cover is mine though.)

    Clover doesn't give up his soul because justice still needs to be delivered. The Wild East, and later practically the entire Dunes, declares independence. They declare that any human within their borders is under their protection. Civil War looms over the Underground. Would you like to see what happens? Note: This is NOT a story. This is an archive containing information about my AU, Desert Sanctuary. I might write a proper story in the future, but for now, this is where you can read about the narrative, the characters and how this massive change affects Frisk's journey. Fanart and other fan works based on Desert Sanctuary are welcome and encouraged

    Cover image made by me. Someone meets their end too soon and meets someone who gives them another chance to live a more fulfilling life. One that they would enjoy despite the problems that may come along. In other words, reader becomes Error.

    (TW: unaliving thoughts and memories at the beginning. It gets better over time, don't worry! Trauma is difficult to overcome...) You didn't want a second chance. You didn't want to survive. You wanted the sweet release of death. But it seemed like the universe was far too cruel to allow you even that. It took away your memories, your free will to choose whether you live or die...hell, it took the one thing in life you owned! Your own name! And now it seemed like you had to live yet another cruel life, doing things you never wanted done to others. But...at least you could do things your way. Maybe this second chance wouldn't be so bad... (Reincarnated as Nightmare Sans, but unlike other stories, you have no clue what Undertale even is) (WE REACHED NUMBER 1 IN THE UNDERTALE TAG YOOOOOOOO) (9/13/25)

    Why Toriel, with her creepy obsession with the fallen children and in need of Therapy. Was it truck-kun? They'd rather like to know, and really hoping this is cannon and no Genocidal children At least its after the run to the ruins portion they took over Co-written with Philippaki!
