Y/n has been trapped in her own mind as the monster was beginning to take control. Everything around her was pitch black, and the silence was sickening. She stood up and stared down. Her reflection showed her in her human form. Y/n scoffed and tried to grow her wings. When they didn't come out she turned her head confused. "That's odd..." Her voice echoed, and she could hear something closing in.That something seemed to be flying twords her at a great speed. She frantically looked around but didn't see anything. The void around her shook, and she fell down to the floor. A glitching sound suddenly filled the void and someone began to appear in front of her. "☜︎☠︎☺︎🏳︎✡︎🖐︎☠︎☝︎ ❄︎☟︎☜︎ ☼︎🖐︎👎︎☜︎✍︎" Her eyes widened as she watched the rest of the person appear. "You're that guy from the party... That was sitting in the corner alone." The person smiled. "🖐︎🕯︎💣︎ ✌︎☹︎💧︎🏳︎ ❄︎☟︎☜︎ 🏳︎☠︎☜︎ 🕈︎☟︎🏳︎ ☹︎☜︎☞︎❄︎ ❄︎☟︎☜︎ 👌︎✌︎💧︎😐︎☜︎❄︎📬︎ 💧︎🏳︎ ☝︎☹︎✌︎👎︎ ✡︎🏳︎🕆︎ ☼︎☜︎💣︎☜︎💣︎👌︎☜︎☼︎ 💣︎☜︎📬︎" Y/n stood up again and glared at him. "You're the one who left the basket... You brought me into this mess?! I was better off there!" He shook his head and glitched for a second. " I've been watching you since you were a child. I know what's better for you."
Y/n felt another quake, making her wobble a bit. "What do you mean you've been watching me? And how do you know english?" He laughed with a glitched voice. "I created you and others like you. You were test subjects that were supposed to break the barrier." She gasped and stared at him in disbelief. "Who are you.." Y/n growled and clenched her fist. "And what are you talking about, I was born from my mother and father!"
He walked closer to her, stepping into the little light left. "They never told you? Interesting. My name is W.D. Gaster and your parents stole you along with the others. When they realized they couldn't take care of you, they sold you off to that circus. When I finally found a way to interact with your world I left a basket for all of you to open together." He paused and waited for her reaction.
"W-what?" She asked. His smiled widened as he continued. "The reason why Nightmare wants you so bad is so that he can give you to me. You see. Me and him made a deal. He gets you to me since you're the only one that touched the basket. And I give him all the power he's ever wanted." She fell to the ground on her knees and stared in shock. "So I'm just... A science experiment?" She choked out. "That's right." Black tentacles rose from beneath her and wrapped around her. Y/n's eyes lost color and she was emotionless. Gaster disappeared with a smirk. Y/n began to be dragged into the darkness.
Outside Y/n's mind
"WE HAVE TO FIND OUT HOW TO STOP HER!" Blueberry yelled. "SHE COULD LOSE FULL CONTROL ANY MINUTE NOW." Blueberry dodged another attack from Y/n and Ink painted spikes around her. "Y/n can you hear us bruh?!" Fresh shouted. She screeched at him and cut at the spikes. "I don't think she knows us well enough for us to bring her back." Dream said. They looked at each other worried. "Let's hope she can fight it off."
As Ink said that the feathers and black skin started to fade from Y/n. Her eyes blinked a few times before closing. She started to fall to the ground so Ink took away the spikes. Fresh ran and caught her before she could hit the floor. He put her down gently with a slight blush as the others surrounded her. Dream checked for a pulse and sighed in relief. "Will she be ok bro?" Fresh asked. "I sure hope so." Dream replied.
A portal began to appear below her. They all noticed and went to grab her at the same time. They bumped skulls and fell backwards as Y/n fell into the portal. They rubbed their heads and sat up. Y/n was gone and Ink sighed in annoyance. "Where did that portal even come from?!" Fresh shouted. "I'm not sure, and I don't have enough Ink to create one. I'll have to restock." Ink sighed. "BUT SHE NEEDS US NOW." Blueberry said worried. "Don't worry blue, we'll get her back soon." Dream patted Blueberries shoulder and stood up. "We should regroup first." He walked away and started at the sunset from under the tree.
Y/n POV
I groaned as I sat up. "What... Happened?" I asked and looked around. "You fell through a portal and landed on my sister." Growled a tired voice from behind me. I quickly stood up and looked to where I landed to see another version of Sans. "I am so sorry!" I apologise and helped her up. "It's no biggie. You were completely limp while you were falling." While she continued to talk I felt nauseous and blacked out.
The AU in the next few chapters is not mine and was created by panpankate here on wattpad! They gave me permission to use their AU for my story. If you'd like to know more about their AU (Makertale) you'd have to ask them.
