It's been five years since the battle with Flowey. While the monsters are all still trapped underground, they have a new, brainwashing ruler - Mettaton has usurped the throne in the absence of Undyne and the long-lost queen Toriel, and the Underground is worse than ever. Only a band of rebels hiding deep within the Ruins are what stands between total conquest of the monster kingdom and freedom. King Mettaton AU. Female!Frisk.
A/N: Hey, guys! I'm uploading this to Fanfiction from Ao3 now! Please note that in this story, things will be a little bit different. Yes, Mettaton is king, BUT there shall be plot twists! And Frisk is in there somewhere. Yes, Frisk is a girl in this. And how does Flowey tie in? Oh, just you wait. For now, please enjoy! Note that I do not in any way own Undertale. Undertale belongs to Toby Fox. Be warned: There are OCs.
Chapter 1: Five Years After
The entirety of the Underground was a terror.
Buildings, shining like gold, reached towards the highest points beneath the Mt. Ebbott. Banners flew and pink and gold were everywhere.
It was disgusting.
The shadowy monster glared at the cities in the distance. Ever since he had taken the throne, things had only gotten worse.
The monster turned to his ally. They had both grown since the human Frisk had fallen into the Ruins. Their innocence was gone; eyes like steel, impenetrable armor adorning their muscled bodies. They had become soldiers for the cause, or so they passionately claimed.
The monster's ally had gone under a change, knife gripped tightly in their fist. Their open eyes, a piercing earthy brown, had lost their childlike happiness, their lips, the bottom one split, were drawn in a heated sneer, their long, choppy hair caught in a tight bun on the back of their head.
They hadn't been the same since the takeover.
He had once been her friend, what seemed a lifetime ago. But after he took the throne, he had changed. She knew it, he knew it, the whole kingdom knew it.
It sickened her. That's why everything was the way it was now, and that's why the people weren't satisfied.
Well, at least some of them were.
It was a common rule; everyone who disagrees disappears. And she knew exactly who the monarch had picked to do it.
A tear pricked at her eye and a lump began to catch in her throat.
"You ready, Red?" The monster asked, sparing her a concerned glance for a moment before it changed back to its stony facade.
It took her a minute to answer as she wiped the tear away harshly and looked at him with determination. "Let's do this, Stripe."
The two took off in the shadows, vanishing into the night.
"Your highness, shall I get an opinion on the matter?"
"Ohhh yes, darling." He purred, wine glass in hand. The liquid inside was unknown to most; only him and his crew knew what it was. His lightly-toned legs were crossed, one over the other, his signature pink heeled boots partly visible under the cape. "I agree wholeheartedly."
"All in favor of the law of Metta Flakes, say 'I'." A male's voice rumbled, and all of the councilmembers droned in a simultaneous 'I'.
"It's settled, then. From now on, the only breakfast cereals shall be MTT-brand Metta Flakes. Temmie Flakes are hereby banned from the kingdom." An eye flashed. "Any seen eating Temmie Flakes shall be hereby...taken care of."
"Excellent, darling. Have the order out by tonight." The king's lips formed a grin as he took a sip of the drink. "Any word about the arrangements for the new prisoners?"
"Yes, your Highness." A councilmember bowed to him before standing. "The newest prisoners, a male and female human, have decided to defect from your fanclub. They were captured by some villagepeople early this morning, and their fates are yet to be determined."
"Hm, such a shame, really..." The king mused, his chin in his hand. He brought the other up in a dismissive wave. "Send them to the Tower tomorrow evening. And make sure to keep a good watch over them this time."
His bright magenta eye narrowed and his smile downturned into a frown. "We don't want the rebels to get them again, do we?"
"N-no, of course not, your Highness. I shall see to it that they remain under heavy, um, guard, that they shall be escorted to the Tower tomorrow..." The councilmember trembled under the king's harsh gaze and returned to their seat at the table, words reduced to incoherent mumbling.
One councilman looked at them suspiciously, but said nothing as another member stood up to report.
"My king, before I report, I must warn you that you will not like what I have to say." The councilmember, a female, wore a grave expression.
"...Go on." The king looked hesitant, but nodded.
The woman took a deep breath, and then meekly muttered, "The Rebels have taken control of the Ruins."
"I'm sorry, darling, what was that? I couldn't hear." The king squinted, leaning closer.
"T-The Rebels have taken complete control of the Ruins, sir." The woman looked deathly afraid; almost as if he would have her head if she continued.
There was a deafening silence. Every eye turned from the terribly shaking woman to their king, each silently hoping he wouldn't get too mad at this awful news.
The silence lasted for a minute or so as the king registered what was said. His head was bent so no one could see his expression.
Finally, he broke the silence. In a deadly, low whisper, he asked, "What?"
The woman dared not say a word, only looking at her feet.
There was a pregnant pause as the king looked up, and every member of the council, save for one, immediately grew afraid of his building wrath.
"Double the guards." His voice was harsh with rage as he stood. The woman grimaced, sitting right back down, not daring to look him in the eye as he continued. "Double the weapons. Double everything, damn it! I want those Rebels caught and tried for their treason!"
"Y-your Highness-" One tried to speak up.
"This meeting is over!" The king's voice rose in volume, and at once almost everyone stood, bowed, and hurried out of the meeting room in terror. Only two remained; his most loyal servants.
The king walked past them, but stopped. He looked back at them with a commanding expression. "Sans, Papyrus...you know what to do."
He stormed out of the room, the door shutting loudly as the two brothers looked at each other, one terrified, the other solemn, and at once, they knew what had to be done.
A/N: Dun dun dun! Ending on tension! At least we know where Sans and Papyrus are. Things are gonna heat up soon, so please stay tuned! But just as a warning: I'm in school, so this story won't get updated as quickly as I'd like it to, because I don't have good Internet. I'll hopefully update fast enough so that it doesn't get boring waiting around for me to make another chapter, but slow enough so I can actually write the darn thing. Sound good?
Also, please note: I know I haven't (and won't) hide some characters' identities well, but please, for the sake of the story, and for my sake, PLEASE DON'T SPOIL WHO THEY ARE IN THE COMMENTS. You may feel free to message me about your hunches on who they are, but whatever you do, DON'T SAY IT IN THE COMMENTS. I'm planning a big reveal about several chapters in, and I don't want anything spoiled too badly.
Thank you, and please stay tuned for the next chapter!
