Gaster AU x Reader ONESHOTS

Fell x Bubbly! Kind! Hurt! Reader 1

You were from (AU name), and your friend Dream gave you some of his powers to help people. Living with the Gasters reminded you when your family was in poverty. You decided to do something for the guys, give them each a different gift.

You walked into the lab to see WingDing looking tired. A small flashback came and you saw your mother looking tired with all her paper work. You gave your head a shake before walking over to WingDing. "Hey!" WingDing looked at you and your usual smile. "Ah, hello (y/n)."

You pulled out a bracelet aligned with orbs that held stars. "Here." WingDing look the bracelet before seeing you taking his other hand and laying it on top of the bracelet. You stepped back before the two of you saw a large light show. "Those are your hopes and dreams," WingDing and you looked at each other as you smiled, "keep them close."

WingDing nodded before you walked out to find Stars. It didn't take long. You gave him the same bracelet as WingDing and showed him how it works. You walked into the kitchen to see Swap. "Hi Swap!" Swap looked at you and smiled.

"Hi (y/n)! What do you need?" You pulled out a frying pan, it was aligned with stars and other designs. "Wowzer! This looks cool!" You smiled as Swap ruffled your hair. "I'm guessing B and Fell are in the living room?" "Fell is. B is resting." You nodded understandably.

"Hey Fell!" Fell groaned. He thought you were too happy in a place like the void. Even though he would never admit that he thought you were cute, he thought you were pretty annoying. "Here!" Fell saw you holding a bracelet. "I made it with my magic, so, don't break it."

Fell didn't pay attention as you gave him the bracelet and left. He huffed, not knowing what you meant by 'magic', before he snapped it in half. Suddenly the whole house was filled with your screams in pain. Fell got up and raced into the hallway you were in.

WingDing, Stars, and Swap were behind him as you covered your mouth. Blood trailed down as tears filled your eyes. WingDing pushed past the others and got you to your feet. "Swap, make her something to eat." Swap nodded and raced into the kitchen. Stars helped WingDing get you to your bed.

Fell just stood there, his face read horror. 'What the f@!k did I just do? No, that wasn't me. ... was it?' Fell thought to himself before hearing you crying in pain. Fell trotted by your door, making sure WingDing, you, or Stars couldn't see him, as he listened.

"It huurts!" "We know. We know. By Asgore, your soul..." "It'll be ok. I promise." "Aaaaahaaaa... Make it staaaaap..." Fell quickly left as Swap carried a plate of (fav/food) to your room. Fell never felt so much guilt. You did nothing to him and he stabbed you in the back.

~ Time Skip ~

You laid in as your soul looked about ready to shatter. You closed your eyes as tears rolled down. You KNEW Fell broke the bracelet because you felt it before. You made the EXACT same bracelet for your older brother before he got hit by a truck, his bracelet broke in the process.

B did find out what happened and he allowed you to use the blanket you made him (which was suppose to heal his soul quicker). You couldn't move your legs without help. "I... never wanted to feel like this again... why..? What did I do..?" You whimpered as you hugged yourself.

You heard a knock on the door before opening your eyes. "Yes?" You said as you kept your back against the door. "(Y/n), it's me. Fell." You growled as your eyes glowed red for some reason. "Go away. I know you broke the bracelet." "But-" "I SAID GO THE F*CK AWAY!"

Fell backed away before leaving. He huffed before seeing Swap. "You... broke something she made for you?" Swap asked. "I didn't know that would happ-" Fell started, "Not the point! She did nothing to you and you stab her in the back!" Swap barked before walking away.

Fell sighed. He'd hate to admit, but Swap was right. You did absolutely nothing to him except help him. Fell went to his room and laid on his bed.

"I'm so sorry (y/n)."
