***Hello, everybody! So while I was listening to "Nitro Bot" by Sentai Express, this whole story idea came into my head. Do not worry about background being explained here, because I believe at least a good deal of it is explained within the chapter. Alphys and Mettaton belong to Toby Fox, the story plot belongs to me, and let's jump right in!

Chapter One: What Do You Think?

"You called for me darling?" Mettaton Classic asked, stepping into his best friend's primary lab. "Y-yes. Please, s-sit down. Over th-there. Stop me if y-you aren't interested in wh-what I'm gonna t-tell you," Alphys permitted, standing in front of a table.

"Okay," Mettaton said. He rolled over to the chair at that table. "...darling, you've got to remember that I cannot sit down in my main form," he deadpanned.

"O-oh...right. I'm s-stupid. Anyways, it's c-c-coincidental that you m-mentioned your form j-just now. You kn-know your three o-ones," Alphys said. "Classic, EX, and Neo. You should know that, you built all of them," Mettaton recalled. Alphys nodded.

"C-correct. W-well, I've been r-re-evaluating your Neo f-form. Its weakness is d-defense. And th-that's on me, I'm s-sorry. But the d-defense is, f-for lack of a b-better word to d-describe it with, c-crap. And with wh-what's been happening l-lately, low defense can b-be your quick d-demise," she said, her voice hushing as she said the last thing. Mettaton hummed, a solemn line of red now across his paneled face.

It had begun to spread across the Underground, by experience or by story, that a human had fallen down. And they were killing monsters left and right.

"So what is it about my form?" Mettaton asked, trying to distract both himself and Alphys. She snapped out of her trance induced by sadness. "O-oh! So, I've c-created some new d-designs for an ever b-better form," she opened. Mettaton's facial panels lit up to show a question mark. "Oh? Tell me more," he inquired.

Alphys grabbed a poster-sized paper that turned out to be a blueprint that had been previously unnoticed on the table. She held it up. "I c-call it, Mettaton N-Nitro," she announced. Mettaton rested on fist on his boxy body. "Again I ask of you, tell me more," he insisted.

"S-sorry. I, uh, g-got excited. Anyways, b-beyond the exterior-b-because I know th-that that matters to you-lie amazing s-stats," Alphys said. She handed over the blueprint, pointing to section detailing stats. Mettaton took the blueprints and looked at that particular section. "30,000 HP, 95 (25) attack, 255 defense," he read.

He looked up from the blueprint an exclamation point on his blocky face. "Darling, these...this is amazing! These stats are much better than my Neo form! Although your handwriting is chicken scratch, to be honest. But that doesn't really matter!" he said. He put the blueprints on the table next to him and barreled straight ahead.

Alphys started scrambling backwards. "D-don't hurt me, don't r-run me over!" she pleaded. Mettaton willed himself to a stop. "Sorry. I got excited and wanted to give you a hug," he said. Alphys moved away from the wall, which her back had slammed into in her attempt to not get mowed down by her own creation. "Y-you can hug m-me. Just...d-don't hurt me," she said.

"Right," Mettaton said. He wrapped his arms tightly around Alphys, who hesitantly hugged back. After a few seconds, they pulled apart. "I-I'm so glad y-you like my idea. I r-really thought y-you wouldn't like it b-because of the a-anime-like design," she admitted.

"For once, your trash cartoons have produced something strong and sleek for me. Good for you," Mettaton said. His panels lit up to show a friendly smile. "S-so, I have th-the necessary pieces th-this project. Sh-shall we begin?" Alphys asked. "Yes," Mettaton replied. "Th-then follow me," Alphys said.

As he followed her, he couldn't help but feel fierce DETERMINATION fill him. He had been Classic, EX, and Neo. Now, he was ready for Nitro.

***As for what Nitro form looks like? Don't worry, you'll see that soon. Anyways, be sure to leave a review on the way out, and I'll see you all in the next one! Bye!
