Undertale x Child!Reader Scenarios

Mini-Me(ttaton) [Mettaton x Robot!ChildReader]

Another Mettaton one because he is best fab robodad! And in this one he will switch back and forth between his boxlike form and EX form. With that, enjoy the story!

Even stars get bored sometimes. Just because someone has a busy schedule doesn't mean they can't want something more, something more fulfilling.

Which is why Mettaton asked Alphys for a child.

"Y-you want a wh-what?" The reptilian monster asked, adjusting her reading glasses.

Mettaton put his hands on his hips (or lack thereof, since he was currently in his less extravagant mode). "You heard me, Doctor! A child! I need someone to look after, someone to teach the ways of stardom, a mini-me, if you will."

"I s-suppose I could make another robot..." Alphys muttered.

And another robot is exactly what she made.

In just a few weeks, it was built. It looked like Mettaton's EX form, but a lot smaller, with flat "shoes" instead of high heels, and the pink areas were instead (F/c).

Mettaton himself decided to switch to EX form for the occasion, in order to make a good first impression. As Alphys put the finishing touches on the new robot, the old one kept rambling excitedly about all the things he was going to do with his protege.

"Oh, I'll have to bring them onto my shows, they'll learn to love the spotlight! I can teach them my cooking skills too! I'll introduce them to Frisk too, I hope they become good friends!"

"Mett—"

"I wonder if I shall homeschool them or send them to a regular school?

"Mettaton!

"Yes?"

"It's almost ready," Alphys announced. "I just need to input a name into the memory presets."

"How about......"

Just a few days into your existence, and you were already being overwhelmed by fans of your father. They were calling you things like "Mettaton-Mini" and "The New Mettaton". Your father was usually there to step in and drive away the ravenous fans, news reporters, and occasional haters.

But today, as you sat on a park bench while waiting for your dad to get done doing autographs for the swarm of fans that had showed up and demanded his attention, you failed to notice a human kid sneaking up behind you.

The kid dumped a full bottle of water on you, then ran away laughing. You screamed, which caught the attention of your dad. He pushed his way through the crowd of fans and knelt down next to you.

"(Y/N), darling, what happened?! Why are you soaked? You know water isn't good for you!"

You were already starting to spark and fizz. "Someone ran up and dumped water on me, I didn't see who..."

Panicking, he picked you up and sprinted out of the park. "Oh goodness, I must to get you to Alphys before you short-circuit, or worse, rust! Hang in there, my shooting star!"

Everything afterward was a blur. You could recall the lights of Alphys' lab, your father's voice tinged with panic, and above all, so much pain.

It was unclear how long after the initial incident you woke up again. You were in an unfamiliar part of the lab, and you were alone.

You tried to move, but found that your limbs were gone. You looked down and— wait, you couldn't do that either! It seemed that you were reduced to your basic structures: Head and core. You were suspended above the floor and kept running by wires and tubing hanging from the ceiling. From what you could feel, your artificial hair and some of your facial plating was gone too. Was the water damage really that bad?!

You tried calling out, but it appeared your voice box was gone too. All you could do was wait for someone to come to you.

Luckily, it wasn't long before Alphys came in. She smiled upon noticing you were awake.

"Everything will be ok," she reassured. "The water did a number on you since it took a while for Mettaton to bring you to me, but I'm working on new accommodations for you right now! I'll tell him you've woken up."

Alphys left, and within moments a flustered Mettaton EX rushed in. He took one look at your incapacitated state and gasped dramatically.

"Oh, my darling! I can't believe this... it's all my fault for not watching you properly! I'll make it up to you! I'll have Alphys make your new body better than the last one!"

You desperately wanted to tell him that it wasn't his fault, but of course you couldn't talk, and he rushed out right away after that.

All you could do was wait, again.

Hours later, Alphys returned with a cart holding a slew of parts wheeling along behind her. You watched curiously as she attached the parts to you one by one, building a brand new body piece by piece.

It ended up being a little bit taller than your last one, and your hair was now (your hairstyle) and multicolored. When you finally left the lab to see your father, he immediately gushed over your new form and embraced you.

"Oh, it's like you've gotten older! You look glamorous, my dear!"

"Heh... thanks, I didn't make it," you remarked.

"Oh of course!" He turned to Alphys. "Thank you so so much for fixing my precious blossom, Doctor! I owe you."

"Erm, n-no problem," Alphys said coyly, although you sensed she was quite proud of herself.

Mettaton turned back to you. "Shall we go show off the new you? I'll try not to let any nasty haters get you this time."

"Yeah... let's go, dad."

And together, you and your father were absolutely fabulous.
