Author note will now be at the beginning of every chapter! Also, the text will be centered. I want to thank you all for 300+ reads as well! Now continue on fellow Undertale lovers! The AU mentioned to be Y/n's was created by Le fun shark. I give all credit to them! There will be a use of bad words in this chapter. (Idk what else to call it)
"And that's what my world is like!" Y/n finished. Dream put a finger to his chin in thought. "A mutation AU? That must be a new one that was created by the upper creators(You and me)." Dream pondered. "Upper creators?" She asks with a tilt of her head. Dream nodded in response. "They create AUs, Ink only helps them with it." Dream explained. Y/n was still a little confused, but got the gist of it. A black inky portal opened from the floor. Ink jumped out with a few cuts on his bones.
"There you are Ink! Where have you been?!" Dream shouted, sounding like a mother. "I ran into error." He replied flatly. Ink then took a vile from his satchel and drank it. "Did you find out what AU she's from?" Ink asked, still having a monotone voice. "It's some kind of a mutation AU. I'm thinking it's a new one." Dream replied. "Do ya have anything similar to that bro?" Fresh asked. Ink stared into space for a little. Then nodded his head. "It's called Freaktale. She might be from there. Though I'm not sure." Ink said, a bit of emotion in his sentence. Y/n frowned at the name. "That would make sense. We are called 'freaks' and 'monsters'." She says with a sigh. Dream and Fresh look at you with sympathy. Ink looking slightly sympathetic.
"The Sans in Freaktale has two forms. It is a recent one, so I'm not sure if other people do. Besides the Virus of course." Ink explained. They all sat in thought as Y/n spaced out. The three skeletons began talking again. Y/n came back to and listened to their conversation. "So if they have two forms... Does that mean that Y/n and the other mutation humans do too?" Dream asked. Ink shrugged and turned to her. "Y/n, try turning into something else." Ink ordered, catching Y/n off guard. "Wha- I don't- What?!" Y/n shouted in confusion. "Try thinking of a different form than the one your in now." Dream suggested. Y/n looked between the two of them. Then slouched and sighed. "Alright, I'll try." She mumbled. She stared off into space and began to think about herself looking human. She pictured a normal s/c with no darkness. Eyes being a normal e/c instead of dark and empty. The wings on her 'perfect self' were gone, and so we're her tail feathers. She heard Dream gasp and looked up. Her 'perfect image' disappearing from her mind.
"What?" She asked. "It worked! Sort of..." Dream said. Y/n looked behind her to see her wings shrank and her tail was gone. She checked her skin to see it was almost normal. She looked to Ink. "What color are my eyes?!" She asked. Ink stared at her and his eyes went wide. "They're bright and e/c." Ink said with a smile. "Nice! Let me complete the rest." Y/n said. She closed her eyes and thought of the same image. She felt her wings shrink more, until she couldn't feel them anymore. Then her skin tingled, and stopped. She opened her eyes and checked again. Her wings were fully gone and her skin was normal.
"Whoa." Was all she could say. "I'm human!" She rejoiced. "I thought ya were already human bro." Fresh stated. "Well, not really, especially with the mutations." She says. They all shook their heads. "Mutations or not, you're human." Dream states, Ink and Fresh agreed with him. Y/n smiles at what they thought. Bringing them all in for a group hug. "Thanks guys." She says, then lets go. "I'll use this to my advantage when I get back home." She states.
Ink nods as he takes out his brush. "Wait- before you take be back home. Can I say bye to those I got along with?" Y/n asked. Ink thought for a second, then looked at the others. The three of them nodded. She smiled and jumped up and down. "So, who do you want to say bye to?" Ink asked. Y/n thought for a moment. Trying to think of who she meet and got along with. She knew classic Sans and Papyrus, Fell Sans, Reaper Sans, Underswap Sans and Papyrus, Aftertale Sans, Birdtale Sans and Papyrus and the three in front of her. Of course she's meet a few others, but she doesn't know them too well. Y/n looked up at Ink and smiled. " I would like to say bye to Underswap, Undertale, Aftertale, Birdtale, Reaper Sans, and Fell Sans." She said. Ink had wide eyes. "That's a lot but ok." He then used his brush and swiped at the grass. Everyone you chose popped out. They looked around confused untill they all saw you. "Y/n?" They all said, besides Fell Sans. Who was nervously sweating.
"Hey everyone!" She exclaimed with a closed eye smile. A few ran forward and hugged her. Them being Undertale Papyrus, Underswap Sans, and Birdtale Papyrus. Y/n hugged back, then they exited the group hug. "Why'd you bring us here Ink?" Classic Sans asked. "Y/n wanted to say bye to all of you. She's going back home." Ink said. Fell became more nervous and made his way to Y/n. He grabbed her arm and the others looked at him with suspicion. "I'm sorry." He whispered. She was now back in her cell. She began to panic, not realizing that Fell left and locked the door. Nightmare appeared out of nowhere and fed off your negative energy.
You looked up and saw Nightmare reward Fell. "Why?" You asked Fell. He looked down in a guilty manner, avoiding your gaze. "Because he wants to protect his home. The lives there matter more to him than you do. You did just meet the other day" Nightmare answered for him. A tear fell from Y/n's cheek. Nightmare had a wide grin. They both teleported away. Revealing Error standing 6ft from your cell. His smirk was sinister as he approached the bars. "WeLl, wElL, WeLl. LoOkS lIkE tHeY cOuLd'T kEeP yOu 'SAFE' fOr LoNg." He spoke with a chuckle. She glares at him then sits on the floor. Bringing her knees to her chest. "NoT eVeN g-gOinG to ReAsPoNd?" He teased. Y/n 'tsked' and looked away. "By tHe Way, WhY dO yoU lOoK d-different?" Error asked. Y/n rolled her eyes and went back to her 'normal' form.
His eyes widened then went back to normal. "So YoU'rE a FreaK." He asked and raised a 'brow'. This definitely hit a nerve. Y/n lunged at the bars and glared at him. Error stared at her with annoyance. She wished she had power- ANY power, to beat the living shit out of him. Then a lightbulb came up. 'What if I have more than two forms?' She thought. Y/n then looked at Error with and evil smirk. This caught him off guard. She thought of a new form quickly. Black claws that faded into the hand and replaced your fingers. Smaller wings to enhance agility. Pointed and thin tail feathers. Then her eyes, she wanted to strike fear in people. Her eyes were pitch black, like and empty void. Y/n stared at Error, then realized his eyes had a slight hint of fear.
She chuckled, which echoed like a demonic voice. Error used his strings to try and grab her soul before she moved. She sliced them with her claws and gave Error a dead look. He backed away from her cell as she sliced the bars, chipping them a little. "NIGHTMARE!" Error shouted. Y/n, along with Error, were witnessing her TRUE power. Y/n's soul glowed a bright f/c, and she cut the last of her bars off. Without a second thought, she lunged at Error.
