Undertale AUs Wiki
Advertisement

MysteriousTale is an Undertale AU created by the artist and sometimes fanfic writer MinecraftFan11 (also known as MinecraftFan11Scr/MinecraftFan11onScratch on some other accounts).

It is a crossover AU mixing different video-games, a movie, and some cartoons in the role of the monster-kind of Undertale.

Opening Sequence[]

In 2009...

There was a HUMAN girl called "Coraline".

She moved to the Pink Palace in Oregon, because of the gardener job of her parents. She couldn't get their attention, and her neighbors were eccentric and annoying to some degree.

She wished for adventure, for fun, to be loved and cared for. And then, she remembered a tale her neighbors told her.

The tale of a mountain...

Mt. Falls

The tales say that some amazing kind hides on the mountain, but that nobody who climbed it ever returned to tell the truth.

...

Notable Changes[]

General Changes[]

  • Characters from video-games, some cartoons, and one stop-motion movie replace the Undertale cast.
  • The Story is an alternative coming-of-age plot for Coraline, who, instead of finding a door to an idealized world, decides to explore a mountain shrouded in myth.
  • The mountain is named "Mt. Falls".
  • The Golden Flowers are traded for roses of orange and magenta colors.
  • The main SOUL has an orange half and a magenta half (representing the two colors of the most known shirts/sweaters Dipper and Mabel wear).
  • The main SOUL modes swap in a circle (Yellow replaces Blue, who replaces Green, who replaces Yellow). A Cyan mode, where the SOUL (restricted to a circle movement) moves in a slower velocity than the regular one, replaces the Purple mode.
  • All the areas are changed up.
    • The Hidden Palace is a fusion of the level design of the Ruins (plus a few twists) with the appearance of the level "Hidden Palace Zone" from Sonic & Knuckles.
    • Recording Snow is pretty much Snowdin, but more suited to a cartoon of the 30's/40's and more dull-colored.
    • Emeraldaqua is made of dark green emeralds and has a slightly different design.
    • Dreamland (no connection to Kirby's setting) possess cosmic and dreamy themes, instead of lava-cave-like themes.
    • The Cave Lab is pretty much the True Lab, but more cave-like.
    • Green Hill Palace mixes New Home with the colors of "Green Hill Zone", the first level of Sonic the Hedgehog, and one of the most iconic levels of the Sonic franchise.

Character Changes[]

Main Cast[]

  • Frisk is replaced with Coraline, the titular protagonist from the stop-motion movie Coraline. Just like in her origin movie, she is a tomboyish and snarky adventurous 11-years old girl that suffers great character development (but in this AU, it can be either for the better or for the worse). She speaks more clearly than Frisk does and her development can be seen over the course of the main routes.
  • Chara is replaced with Dipper Pines and Mabel Pines, from the Disney cartoon Gravity Falls. Both Dipper and Mabel are responsible for the narration of Coraline's adventure and represent both sides of the original Undertale narration: Dipper gives mostly informative and serious information while Mabel jokes around with some of the surroundings. Dipper's personal narration color is orange while Mabel's is magenta. Their armor item is "Friendship Rings" (only The Rings in the Genocide Route) while their weapon item is "Mystery Book and Grappling Hook" (only The Book and The Hook in the Genocide Route). Curiously, their weapon is the only one in the whole game who allows a dual attack.
  • Flowey is replaced with Bill Cipher, the final antagonist of the Disney cartoon Gravity Falls. Since Bill and Flowey share similarities between themselves, Bill Cipher isn't changed too much on his personality and behavior but has his power cut out to be equal to Flowey (except on levitation). Instead of "Friendliness Pellets", he uses "Blue Flames of Harmony" (or "Blue Flames of Doom", as he almost says in case his flames are avoided), and he has a pink-and-orange rose attached to his hat.
  • Toriel is replaced with Amy Rose, one of the heroines of the Sonic the Hedgehog franchise. Like Toriel, she left Sonic because of disgust over his idea to save his people, but she is far more pissed off by the choice than Toriel. She retains her regular personality from her origin franchise (hot-tempered, bossy, but ultimately having a golden heart) and uses her known "Piko Piko Hammer" in the battle on the exit door of The Hidden Palace.
  • Napstablook is replaced with Reala, one of the main antagonists of the NiGHTS games. He tends to treat the humans he stumbles with very coldly, but ultimately, he is just a jerk that somehow needs a comforting hug. Instead of the tophat, he wears his persona (a kind of mask from NiGHTS: Journey of Dreams).
  • Sans is replaced with Bendy, the titular character of Bendy and The Ink Machine. As an opposite of a common Undertale AU Sans, he is pretty cheerful, playful and an active trickster, and loves to dance in his spot without a clear explanation, something that bothers his friends a lot. But he has his serious moments, and it can be quickly found out if one does a Genocide Route.
  • Papyrus is replaced with Boris the Wolf, one of the characters of Bendy and The Ink Machine. As an opposite of a common Undertale AU Papyrus, he is much more chiller, smarter, and laid back, without an inflated ego, but very creative, and still with a wish to join the Royal Guard, so his art can be appreciated by everyone. Instead of bones, he uses pencils with black ink.
  • Undyne is replaced with Yumi Yoshimura, one of the titular characters of Hi Hi Puffy AmiYumi. Retains most of her regular personality (an impetuous and tomboyish girl that acts trough the heart, but hides maturity in herself) and, instead of being associated with the Justice trait and using spears as weapons, she is associated with the Integrity trait and uses guitars shaped to one of her trademark guitars as weapons. Once, was in a musical duo with Ami, but dropped her job to become the Royal Guard Captain.
  • Alphys is replaced with Ami Onuki, one of the titular characters of Hi Hi Puffy AmiYumi. Retains most of her regular personality (a girlish optimist girl with less maturity and a very explored comedic side), but included with the heaviness and pity over the Amalgamates she made with the accident. Once, was a musical duo with Yumi, but dropped her job to become the Royal Scientist, and tried to make a robotic jester fill their holes.
  • Mettaton is replaced with NiGHTS, the main protagonist of the NiGHTS games. Far more childish but friendly and compassionate than Mettaton, and likes to refer to Coraline as "Visitor". Although she isn't as much appreciated as Yumi and Ami where she still tries to gain her spot as the new star of the Underground. Referred to as female on this AU rather than the gender-ambiguous situation on her original games.
  • Asgore is replaced with Sonic the Hedgehog, the main protagonist of the Sonic the Hedgehog franchise. He retains his normal carefree and free-spirited personality but weighted down with the death of his close friend, the death of his adopted children, the heaviness of being abandoned by his love, and with his cockiness heavily toned down. Instead of a red trident, he uses a blue sword similar to Excalibur, but with a pine tree and shooting star (Dipper and Mabel's symbols) figure.
  • Asriel is replaced with Miles "Tails" Prower, one of the main protagonists of the Sonic the Hedgehog franchise. Remains mostly with his, overall, timid but smart and kind-hearted personality, which makes him connect well with the interest with both of his best friends, Dipper and Mabel. However, he recognized that the twin's suicidal plan was wrong and tried to stop them. However, he was unsuccessful, forcing him to go along and, eventually, die and be reincarnated on his favorite plush.

Secondary Cast[]

  • The Dummy from The Ruins is replaced with Peridot, a redeemed villain from the show Steven Universe. In this AU, she is mute, communicating with signs. Curiously, as the opposite from the original Ruins' Dummy, killing her counts on the kill count, since she is a living being instead of a doll.
  • Monster Kid is replaced with Ruby and Sapphire, two protagonists from the show Steven Universe. Both Ruby and Sapphire idolize Yumi like their heroine, but while Ruby undoubtedly loves her until finding out from Coraline that humans and the kind of Mt. Falls can live in peace, Sapphire has doubts if Yumi is all "perfect". They wear a kind of clothing that wraps over their upper body and arms, being the reason they both trip.
  • The Temmies are replaced with Ralts, a Psychic/Fairy-type Pokémon from the franchise of the same name. However, in this AU, their name is spelled as Raltz.
  • Mad Dummy is replaced with Jackle, one of the main antagonists of the NiGHTS games. He is slightly crazier than Undertale's Mad Dummy, and instead of using magic projectiles, he uses cards, just like his original fight on NiGHTS into Dreams.
  • Muffet is replaced with Pearl, one of the protagonists from the show Steven Universe. However, instead of being greedy, she tries to motivate Coraline in being a swordswoman.
  • Nice Cream Guy is replaced with Pleakley from Lilo and Stitch.
  • Burgerpants is replaced with Jumba from Lilo and Stitch.
  • W.D. Gaster is replaced with Alice Angel, one of the characters of Bendy and The Ink Machine.
  • The Amalgamates are replaced with Rayman and various forgotten video game characters. They retain their regular personalities from their origin franchises, but they can not remember anything and they can't talk well, speaking in caveman-like english. However, they can be reminded of their past selves and regain their memories, much like their UT counterparts.
  • Annoying Dog is replaced with Kat from Kid vs. Kat.
  • Royal Guard 01 and Royal Guard 02 are replaced with Timon and Pumbaa from The Lion King.

The Human Souls[]

  • Alice Liddell, from the Disney adaptation of Alice in Wonderland, takes the place of the cyan soul. Her trait is Curiosity. Her armor item is "Black Bow", while the Toy Knife hasn't suffered any changes.
  • Steven Universe, the titular protagonist of the show Steven Universe, takes the place of the orange soul. However, his soul is pink and his trait is Acceptance. His armor item is "Star Bracelet" and his weapon item is "Rose Quartz Shield". It is possible that he and Connie fell together on the Underground.
  • Félicie Milliner, the protagonist of the 2016 movie Ballerina, takes the place of the blue soul. Her soul trait is still Integrity and her weapons aren't exactly different in mechanics or appearance.
  • Connie Maheswaran, one of the protagonists of the show Steven Universe, takes the place of the violet soul. Her soul trait is still Perseverance and her weapons aren't exactly different in mechanics or appearance. It is possible that she and Steven fell together on the Underground.
  • Pucca, the titular protagonist of the show Pucca, takes the place of the green soul. Her trait is Friendliness. Her armor item is "Pigtail Bows", and her weapon item is "Red Gloves". It is possible that she and Garu fell together on the Underground.
  • Garu, one of the protagonists of the show Pucca, tales the place of the yellow soul. His soul trait is still Justice. His armor item is "Katana Scabbard", and his weapon item is "Ninja Katana". It is possible that he and Pucca fell together on the Underground.

Trivia[]

  • Some of the character-themed music makes reference to a characteristic or quote of the same character or even an event on their origin media.
    • Unravel The Mystery (following up the theory that Once Upon a Time is a Chara theme) - Dipper and Mabel, in Gravity Falls, search up about mysteries in the city of Gravity Falls during their summer stay.
    • Your Best Inspirator - Bill tricked Ford on Gravity Falls, presenting himself as a muse who chose a brilliant mind in every century to inspire.
    • Have No Fear - It is one of Amy Rose's quotes on Sonic Adventure 2.
    • The Little Devil Darling! - "The Little Devil Darling" is one of the titles of Bendy and one of the episode posters you can find in Bendy and the Ink Machine.
    • Der Schnellste König Lebendig - This name, translated, is "The Fastest King Alive", making a reference for the most known title of Sonic.
    • Take Back The Mt Falls - Take Back the Falls is the final episode of Gravity Falls, and where Bill Cipher is finally defeated. "Finale" plays at the end of the original Neutral Route fight, when Omega Flowey finally loses advantage towards the player.
    • He Believed in Himself - The Song's motif is "Believe in Himself", Tails' theme song in Sonic Adventure. Also, inspired by the lyric line "I will believe in myself!...This is! The only start for me.".
    • DEMONIAC BRAWL - Bendy's species is canonically stated to be of a demon. Coraline, alongside Dipper and Mabel, can metaphorically become "demons"/monsters by doing the Genocide Route.
  • Some instruments are changed up to specific characters. Some of Yumi's themes possess a guitar in the background while Ami's "The Super-Cute Lab of Ami Onuki" possess drums in the second part background (Yumi is the guitarist of Puffy AmiYumi while Ami is the drummer) while Bendy and Boris' main themes possess some form of piano, like in the original motifs (Build our Machine and Gospel of Dismay). Some of Amy and Sonic's related songs have Sega Genesis/Mega Drive drums and instruments.
  • It is practically a canon fact that the creator chose the song "We'll Meet Again" to serve as Bill Cipher's motif thanks to the fact that in the final episode of Gravity Falls (Weirdmaggedon 3: Take Back the Falls), Bill Cipher sang it while playing the piano.
  • Although this AU's songs are based on the theories that the songs "Once Upon a Time", "MEGALOVANIA", and "Megalo Strike Back" are Chara's motifs, there is going to be a Once Upon a Time for Coraline, a MEGALOVANIA for Bendy and a Megalo Strike Back for Alice Angel.
  • "Duel with the Japanese Rocker" (plus its prequel, "But The Earth Will Be Saved With Rock and Roll"), and Another Dream/Emeraldaqua are all composed of original motifs, or motifs heavily inspired by other songs.
  • Although this AU and Creepytale are two Undertale AUs with vastly different themes and concepts, the creator likes to insert them together, and they share the same Tumblr ask blog.
