Note from the Creator

Freaktale is still under development meaning the story and some of the characters will change with time. This also means the wiki page will changed with the updates new info.

Freaktale is an Undertale AU where Frisk, after seeing every possible ending in Undertale, adds a mod into the game, hoping it would add something new. Little did Frisk know that the mod they installed in was a virus.

After the virus was installed into Undertale, Frisk loaded up the game, but before Frisk was able to start the game. The virus started destroying everything in its path and turning any monster it could find into horrible mutations.


Most of the characters in Freaktale are horrifying mutations due to the virus.

Undertale Characters


Frisk looks and acts relatively the same. The only different from classic Frisk is they are fused with Chara and forced to share a body with them. Frisk is female.


Chara still looks and acts the same, the only difference is that they grew out of Frisk's left side and are now fused with Frisk forcing them to share a body. Chara is Female.


Flowey is a massive red flower with white warts, also known as a rafflesia flower, the largest flower in the world. Flowey smells likes rotting flesh.

When you first encounter Flowey, he is gasping for breath and his voice sounds watery. When Flowey sees Frisk attached to Chara, he starts to twitch rapidly, his roots come out of the ground and are used as legs, Flowey then charges at Frisk and tries to burrow his roots into Frisk. If Flowey is successful, he will start absorbing Frisk's bodily fluids, giving Flowey nutrition, however, Flowey kills both Chara and Frisk in the process.


Toriel looks like a cross between a deer and a goat. Toriel has a second body coming out of her stomach, her arms have grown longer while her feet became hooves. Toriel's horns are more like antlers. Toriel still wears the same outfit as classic.

Toriel went mad and started torturing and eating other monsters just for sport, often tricking her victims by playing hide and seek. Toriel however is nice to Chara and Frisk as she has no interest in eating humans.


Napstablook looks like a ghost version of Chara or Frisk. Napstablook is very aggressive and will kill anything in his path. Napstablook still likes making music.


Sans doesn't look too different from classic Sans, the only difference is he has a massive hole in his skull right above his left eye socket. This isn't Sans's true form, when Sans sees Chara, he has a sudden burst of rage, his ribcage opens up and turns into legs while his real feet fuse together to make a massive tail, or stinger. Sans is a lot more aggressive in this stage and has much more HP.


Papyrus is more aggressive than UT/Classic Papyrus. When Papyrus mutated, his skull got destroyed and he now has a hole in his skull above his right eye socket. Both his arms fell off and were attached to his back, Papyrus's right arm was replaced with a second, non sentient head while his left one was replaced by a syringe. Papyrus uses both of his new limbs as weapons. Papyrus has two bones that stick out of his back making him look bigger. Papyrus lost his leg and replaced it for a robotic leg, Papyrus still wears the same outfit as UT Papyrus.

Canine Royal Guard

All the dogs in the royal guard (including the annoying dog) were all amalgamated beyond recognition. They are all fought where Greater dog is normally found.

Nice Cream Guy

Nice Cream Guy went mad and started killing other monsters. After killing his victims, he freezes their blood and organs and puts them in Nice Cream. Nice Cream Guy has a knife for an ear and his face is horribly disfigured. He kills his victims with an axe.

Monster Kid

Monster Kid is like a wild animal, he is quite aggressive. Monster Kid has a massive mouth with many razor sharp teeth and blank, soulless eyes.


Grillby is a red molten liquid monster with one eye. Grillby is always dripping liquid that is extremely hot, He still acts the same as UT Grillby.


After Undyne was defeated in a battle with the virus, her right arm was cut off and her scales were bleached, turning them white, her eyes fused together to make the impression of 1 eye. Meanwhile, Undyne's right arm was growing back, but it wasn't an arm, it was a spear. While it was happening, Undyne felt a lot of pain. Undyne is always in her Undying form, as when she fought the virus, she was in her undying form. Undyne can't take her armor off as it is fused with her body.


Gerson started believing that the virus was the work of the Gods, so he started to make himself look like the virus by painting his body with blue paint. The virus found this amusing and made Gerson's head into a fox head.

Mad Dummy

Mad Dummy has lost his mind, he became critically insane. Mad Dummy is almost impossible to recognize as he shape shifts into a horrific Voodoo Doll. Mad Dummy may have Rabies.


Temmie looks like a demon ghost cat, with blood coming out of one of her eyes and a strange blue liquid coming out the other one. Despite looking scary, Temmie still acts relatively the same.


Alphys face looks demonic. Alphys is a mad doctor, experimenting and torturing on many monsters just to see if they can free them from the underground. Alphys has a growth on her head which she accidentally injected with determination, thus it's melting.


Mettaton is in all three of his robot forms. Because of this, Mettaton is in failed fusion between his three forms causing him to have two heads in the square panel of his chest. Mettaton is all mangled up and broken. Mettaton EX's head has his lower jaw dropping to the floor, full of razor sharp teeth, Mettaton also has red eyes. Mettaton NEO's head has a demonic face. His voice box is also broken, causing him to have a screeching, static like voice, mixed in with metal scratching.


Muffet in Freaktale has a massive mouth full of massive fangs. Muffet is blue due to a mutation found in spiders that makes them blue.

So Sorry

So sorry still acts the same as classic, however, he is in a lot of pain due to two massive spikes coming out of his cheeks, ears and feet.

Bratty & Catty

Bratty went mad and started eating Catty just for sport, then Bratty took it a step forward and ate her own hand. Then she carved a smile into her face and grew a 3rd arm.

Catty, despite looking dead, is alive and well. Catty seems like she's in pain, but states she feels nothing even though her face is gone and her ribcage is exposed.


Burgerpants still acts relatively the same, the only difference being his appearance. Burgerpants has a club for a tail and is missing his left arm. Burgerpants has bloodied bandages covering his eyes. Burgerpants also carved a smile into his face with a knife.


Asgore looks relatively the same, however, he has four horns instead of two. Asgore has dried blood stained on his cape, his head is a lot bigger and his mouth is filled with razor sharp teeth. Asgore has a second pair of jaws in his throat which are used for grabbing on to food. Asgore has beads that he wears that look like human and monster souls. Asgore will eat anything he can find, from humans to other monsters.


Asriel has red eyes, four horns that are meant to represent his parents, and darker, more torn up clothing. Asriel still acts relatively the same.


Gaster does make an appearance, but he can only be accessed if you hack into the games file, revealing a hidden fight that you couldn't access on a normal play through.

Gaster looks relatively the same to what Gaster may have looked like before he fell into the core, apart from him having 3 eyes, Each eye is a different color with his two big eyes having red pupils, Gaster has a massive smile cut into his mouth, giving him a bloody grin. Gaster is the only monster besides Sans that has a non freak form. Gaster's freak form has two tentacles coming out of his back, and two extra arms that come out of his sides.


The Integrity Soul wasn't attacked until they reached Judgment Hall, there the virus mutated her and gave her 2 extra arms.


The Bravery Soul lost one of his arms, his face is also horribly disfigured and melting.


The Justice Soul was brought to Freaktale after getting tricked by the Virus calling for help, when the soul got to the hole, the virus pushed him into the hole, he then cut his arm off and made a gun grow out of it, he also fused the Justice Soul's eyes together like what he did to Undyne.


Kindness was turned into an albino and lost their face.


The Patience Soul lost both their arms and had a smile carved into their face from the Virus.


The Perseverance Soul was the one who created the Virus, the Virus tricked her into falling into the Underground, after this, she was mutated. She grew a third Eye, and their skin started to turn into scales.

Added Characters

The Virus

The Virus takes 3 major forms through out the AU.

  • His first form is that of a blue Foxy, with a top hat and green bow-tie.
  • His second form is of a young boy, wearing a blue jacket with the same top hat and green bow-tie as his first form. this form, according to the virus, is his true form.
  • The Viruses last form is a Mutated version of the first and second form.

The Virus goes by the name of Sky, Sky is a charming yet insane kinda guy. Most of what we know about him is shrouded in mystery, all we know about Sky is that he is a God, a God who loves seeing others suffer and making his creations suffer.

When Sky made all the monsters in the underground freaks, he thought he made them look "better" and did them a favor. Sky is also the final Boss for the each major Route.


Aya may look like a human at first, but she is actually a monster who was turned into a freak, she is emotionless, she has stitches on her mouth, making it look like she's always smiling, if you cheer up Astral, she will help guide you through Waterfall and Hotlands, However, Aya was not intentionally in the game, which means she could have been added into the game along with the Virus.


Sephtis is a skeleton monster who has a giant red centipede for a pet, He is also the replacement star of Mettaton, he wears jeans and has his pet crawling around him, he also has fangs and cracks around his eye sockets. At this current moment, it is unknown if Sephtis is related to Sans and Papyrus.

The Amalgamates Final Fusion

The Amalgamates stay relatively the same, up until the end of the True Lab, at this point, all of them fuse together to make a melted, disfigured, humanoid being, this being also wears a skeleton mask, The only way to defeat this Amalgamate is to use all the combination from the other amalgamates. After the fight with it, they will all become one sentient being.

Chara's Replacement

Due to Chara being fused with Frisk, Chara has been replaced, she was replaced by a fallen human after her, this human goes by the name of Rouge, he seems like a normal kid at first, but if you agree to give him your soul, he will grow 4 Tentacles on his back, and his left arm will turn into a scythe, this will still happen even if you don't agree. You then get to fight him.
