mettaton X scared child reader

a child in the underground

your name was Y/N. you were 8 years old. you were very small. you had a sister named frisk. she was 12. frisk held your hand as she fought toriel. you felt sad to leave.. she was like a mother... you looked up at frisk. " sis when will we go home?" you asked. "I don't know Y/N.." frisk said.. you started to get tired. " up," you asked softly. frisk smiled and picked you up. you fell asleep. frisk continued walking you got to a snowy area. frisk held you close to try to keep you warm. she went over a bridge. " don't you know how to meet a new pal? turn around. and shake my hand." a deep voice behind frisk said. frisk sighed and turned around and shook his hand suddenly "pffffffffff" a whoopee cushion was in his hand. " haha. the old whoopee cushion in the hand trick. it's always funny. oh, i see you have a little kiddo with ya" sans said looking down at your small form in frisk's arms. " anyways. you're a human right? that's hilarious. " sans said. " I'm sans. sans the skeleton." sans said with his usual large permanent grin on his face.  " I should be at my post looking out for humans. but. y'know. I don't really care about capturing anybody now. my bro papyrus is a human hunting FANATIC. wait. I think that's him right over there. "  sans said.  "I have an idea. go through this gate thingy. yeah.  go right through. my bro made the bars to wide to stop anyone." sans said. frisk nodded and walked with sans through the gate. 

( later ) 

" oh! the human arrives! " papyrus yelled. sans quickly shushed him " bro the human has a little kiddo with them. she is asleep try to be quiet" sans said. " oh right" papyrus said scratching the back of his neck awkwardly. " face my puzzle human!" papyrus yelled. " oh wait.. this puzzle may be to dangerous for the tiny human..." papyrus said. frisk looked down at your small form. " put the tiny human down over near that bush" papyrus said. frisk looked worried at you. she hesitantly put you near the bush. 

( later ) you had woken up.frisk and papyrus were in a fight. frisk was about to kill papyrus. suddenly sans used a gaster blaster and shot frisk with it.. your eyes widened you saw frisk fall to the ground. you ran over to her " s-sissy! f-frisk! please wake up!" you cried out grabbing hold on her bloody sweater. sans looked at you with shock and papyrus. " k-kid i-I'm so s-sorry" sans said. frisk's soul floated in front of you. it shattered. you cried for your beloved sister. you quickly ran past papyrus and sans. " k-kid come back! its too dangerous for you to run off!" sans yelled. you didn't care you just ran.  ( hours later ) you were breathing heavily.  you had been running for a while. you stopped at sometimes to take a rest. you looked around.there was lava everywhere. you looked up and saw a large sign on a building. it said " LAB" on it. you knocked on the door gently " w-who i-is it?" a female voice called from inside " c-can I come in" you asked. you felt like you were going to faint. " o-oh of course" the door opened and it showed a female lizard lady in front of you she saw that you didn't look so good... " o-oh my...  come inside and cool d-down" alphys said worried. " alphys DARLING~ who is at the door?" mettaton said coming in the room in his EX form. " i-its a human" alphys said. your face was red. you had gotten a fevor " alphys darling she doesint look so hot" mettaton said. " y-yeah your right" alphys said. she felt your forehead. you had gotten a fever. " o-oh dear she has a very bad fever!" alphys said. " oh DEAR! she must get some rest!" mettaton said dramatically alphys picked you up, she layed you in a bed. you had fallen asleep. alphys was looking up everything she could to find out what to do to help a sick human. all she found was that they needed to rest and get plenty liquids. 

( later ) you had awakened. you looked around. you saw a robot. " w-where a-am I? what happened?" you said. the robot looked at you " DARLING you've finally awakened~" mettaton said striking a pose. you shrunk in your blanket. you were scared. " darling don't be shy~, " mettaton said. he went to the side of your bed and pet your head. you shrunk back in fear. " darling I won't harm you" mettaton said. he pet your head softly. you smiled softly.  suddenly alphys came in. she had a cup of water. you didn't trust her like you were starting to trust mettaton. " i-i think she wants you to give it to her.. i-i don't t-think she exactly t-trust's me y-yet" alphys stuttered. mettaton smiled and gave you the water. you smiled and drank it. you relaxed and sighed. you got tired. again. mettaton smiled. he and alphys left the room to let you sleep. after a few days, you got better. you spent time with mettaton and alphys. mettaton was your favorite 

you woke up and smiled you went into the lab. " morning alphys!" you said happily. " o-oh! g-good morning Y-Y/N" alphys said looking away from her computer. suddenly there was a knock at the door. o-oh! that must be u-undyne!" alphys said blushing. you had heard to much about undyne. alphys opened the door. a very tall girl with an eyepatch jeans and a tank top and a red ponytail came into the room. " HEY NERD!" undyne said happily smiling at alphys. undyne looked down at you and gasped. " alphys is that a human!" undyne yelled. " y-yes she is" alphys said. " alphys do you realize what this means?! we only need one more soul! we can take that humans soul and break the barrier!" undyne yelled. mettaton came in. " oh I'm sorry darling~ but I'm afraid I can't let you harm this little star of mine~" mettaton came in putting his hand on your shoulder. you were scared. you ran behind mettaton " I'm scared!" you said. " don't worry darling. she won't lay a finger on my little star~" mettaton said confidently. " mettaton move out of the way" undyne growled. " u-undyne n-no! another h-human will fall down here soon! don't h-harm this human! she l-lost her sister!" alphys said. " so what if she lost her sister?! she will be at peace once I get her soul and we are all free" undyne said. " undyne.. sans killed her sister in front of her." alphys said. undyne's eyes widened. " w-wait you mean? papyrus's lazy brother?" undyne said in shock. alphys nodded. you looked down as tears filled your eyes. you were holding mettatons hand. your hand clenched. mettaton knealed down to you. " darling please don't cry.. it wasn't your fault.. you couldn't stop it even if you tried ok? my little star should not cry.." mettaton said softly removing your tears. " f-fine.. but if she gets her soul taken don't come to me saying I did it. alphys im o-only doing this because you asked me not to.." undyne said. " A-alright. how about we go watch some anime" alphys said to undyne.

( a few days ago ) there was a reason that mettaton called you his little star.. its because you loved going to waterfall with him and looking at the sparkly stones in the ceiling that looked like stars. from then on he only called you his little star or Y/N.

( back to the present ) 

you ran up to mettaton. " mettaton! can I call you ton ton?" you asked happily, mettaton smiled brightly. " oh course my little beauty!" mettaton said happily picking you up and spinning you around. you giggled happily. alphys was standing in the background " SO KAWAII!!!!" alphys said blushing like mad. 

( later that day) 

 mettaton picked you up " how about this my little star. we go out for a night on the town. " mettaton said with a smile. you looked up at him and smiled happily. " yay!" you said. " now let's get going!~" mettaton said. " alphys darling me and little star are going out for a night on the town!~" mettaton shouted. " A-alright. j-just try to k-keep her safe" alphys said. " will do darling!" mettaton yelled. you and mettaton went out and spent the night going out to different places. you even made some new friends! suddenly.. " oh hello mettaton!" papyrus waved to mettaton. sans came up behind papyrus and followed him. " *le gasp * sans! ITS THE TINY HUMAN!" papyrus said. you let out a cry and let out a whimper as you hid your face in mettatons chest. " metatton. hand the kid over. we won't hurt the kiddo. we just want to take her home." sans said. mettaton looked at you as if asking if you want to go with them you shook your head no. " sorry sansy darling. I cant do that. you will not be putting your hands on my little star!~ she is staying with me and alphys. " mettaton said. you whimpered and curled up in mettatons arms. " ton ton I'm scared.." you whimpered. mettaton wrapped his robotic arms around you and held you. " ton ton is here dont worry" mettaton said. " kid listen im sorry for killing the human! it was not on purpose! please mettaton just put the human down and we will take her to our place and talk this out." sans said. " my statement stays the same as before. the little star is staying with me" mettaton said striking a pose.  mettaton then walked away from sans and papyrus. he held you in his arms. mettaton got food to take back to the lab for you to eat. you fell asleep halfway there. 

( later) you woke up with mettaton's arms around your very small form. you smiled and snuggled into mettaton. little did you know alphys was fangirling and taking photos with her cellphone.  you cuddled next to mettaton. " my ton ton " you said with a soft voice. alphys was trying to hold in her squeals.
