In another world, the Canterlot High students known as the Rainbooms were all hanging out after practice whilst one of them was laughing.
“I still can't believe that happens when we play! Ooh! I've got to look into some new accessories! Something that looks good in a longer ponytail. Ooh! Maybe some clip-on earrings for when I get those adorable pony ears,” a girl with White as snow Skin and purple hair, named Rarity, stated.
“I just wonder why it happens. Princess Twilight took her crown back to Equestria. Shouldn't that mean she took all the magic back with her?” A girl with tan skin, blonde hair, and a Stetson on, named Apple Jack said curiously.
“Who cares why it happens? It makes my band totally awesome!” A blue skinned girl with rainbow hair, named RainbowDash, said confidently.
“Save your money and breath, amateurs. You won’t even make round one! You certainly won’t make it to finals, not against something as glamorous as me!” A box-shaped robot said as he rolled by.
“First off, Your band? Secondly, are we letting boxes into the competition? How sad,” Rarity of Eques-Earth said behind the Robots back.
“A: Duh! It was my idea to start the Rainbooms so we could be in the showcase. Plus I'm the lead singer and guitarist, and B: Totally agree,” Rainbow Dash of Eques-Earth said acknowledging Rarity’s comment about the robot before they all heard something crash land outside the portal.
“Woah, what was that?!” A girl of bacon looking hair, amber skin, wearing a jacket, violet shirt, and of Equestrian magic, named Sunset Shimmer, said worried and cautious. Immediately she saw people were going to where the crash was heard, and decided to head there by running to where it was.
“Wait, Sunset! We don’t even know what it is at all!” Pinkie shouted as Sunset Shimmer bolted straight to where the crash was heard.
“Excuse me, Pardon me, Coming through, Sorry!” Sunset said to multiple students as she ran past them while they were trying to get to class. Eventually, she arrived where it was, she saw that it was a Blue Police Box, burning and almost destroyed. After two minutes of viewing it in close detail, the doors opened up, and a man with brown hair, green tunic with a silver pauldron on his left shoulder, pouches on the side, red cape, sword, shield, and a burn mark on his right arm jumped out of the box, and landed in front of her.
“Well then, I think that we made it. Oh, right! Where are my manners? Salutations madam, My name is Daphnes Nohansen Hyrule, or Zeldalord if you prefer,” Daphnes said, being polite to Sunset Shimmer, even bowing to her as a sign of respect.
“You really don’t have to be so formal, name’s Sunset Shimmer,” Sunset responed.
“Let’s make this simple,” Serif said, then pulled out one of his AKs “WHERE ARE THE DAZZLINGS!”
“D-Dazzlings?! What’re you talking about?!” Sunset said.
“SERIF, ENOUGH! They probably don’t know about them yet!” Daphnes said.
“It is best if we don’t get involved for the time being,” The Doctor said.
“You don’t get it. This is personal. I got beef on this chick, and it goes way back. And oh, this just got a whole lot more complicated,” Serif said as a blue-skinned boy wearing second-hand clothes rounded the corner. “Doc, get us outta here!” Serif said.
“I don’t care if it’s personal, Serif. You need to let go of the past, for it doesn’t define who you are,” Daphnes said, before dragging Serif away from that student. Before being dragged in, Serif hit Sunset with a memory eraser.
“Well played” The Doctor said.
“If being a standby is necessary then so be it. We’ll wait until Mettaton shows up, and throw him out of the building, and I’ll have to try to use Time Alteration to catch him off guard,” Daphnes said.
Pit was doing aerial recon for Mettaton when he noticed something strange. “Hm? What is that?” he said as he flew closer. The strange happenings were among a trio of teenage girls, one of whom seemed to be under pressure from the others.
“He never would have wanted this,” she said.
“Aria, what’s wrong?” The leader of the group said.
“He wouldn’t want us to do this,” “Aria” said.
“Oh don’t worry about someone who’s dead,” The leader said, and magical energy hit Aria.
“You’re right. Let’s do this. For Her Majesty,” Aria said, then the group approached Canterlot High.
“Her Majesty?? Who’re they talking about?” Pit said, silently flying after them as best as he could.
The Rainbooms, as with the rest of Canterlot High, were sitting at lunch when Sunset Shimmer arrived at their table.
“So how was the tour?” AppleJack said.
“I don't know. I mean, these girls, they were... There was something off about them,” Sunset Shimmer said.
“Like, off like this?” Pinkie Pie made a face. “Or off like this?” She made another face, using carrots and lettuce from her lunch. “Or... Oh, oh! Like—” Pinkie Pie said, before being interrupted by Rainbow Dash.
“Maybe we should just let her tell us,” she said.
“That's just it,” Sunset said. “I can't put my finger on it. They just acted sort of... strange around me. Maybe someone already talked to them. Told them about what I did. So much for making a good first impression,”
“Uh-huh. Oh, that's probably not it,” FlutterShy said.
“Preparing your plan of attack, I assume?” Mettaton said, noticing them. “You know, with persistence like that, you could challenge me, if only you had a little more, pizazz.”
“WILL YOU SHUT UP?! IT’S JUST A MUSIC SHOWCASE!” RainbowDash said, furious at Mettaton.
“Oh, you are so ignorant. But of course, you’re from the past. You have no idea what is to come. It’s hilarious!” Mettaton said. “But wait,” Mettaton said.
“Oh brother,” Shyren said, knowing what was about to happen.
“The scene: a crowded, noisy, disgusting lunchroom, within which the sole inhabitant of any importance is the star of the show, Mettaton,” Mettaton said, posing dramatically.
“Oh give me a break, you’re being too flamboyant,” FlutterShy said.
“He is here, addressing those beings that, in spite of their quintessential inferiority, believe that they can challenge the most beautiful thing to ever set foot in this uncultured pigsty,” He continued.
“Uh, you’re on a wheel,” PinkiePie said.
“Besides, it’s not even a battle of the bands at all, it’s just a music showcase like Dash said,” AppleJack said.
“When suddenly, he is struck by an epiphany: could these seemingly worthless pebbles on the mountain in fact, be hidden geodes of talent and glamour? Could these so-called “Rainnoobs” be in fact, the sirens which he has sought for so long?” He finished, with a dramatically thoughtful pose.
“What do you mean sirens? There are no sirens here anyway!” Sunset Shimmer said.
“Compelling as his thoughts were, he could not be sure. Thus he returned to the vehicle that had become his home away from home on his long and perilous journey, to retrieve a device that could confirm the musings of his mind. Exit Mettaton, Shyren, and Napstablook, stage right.” Mettaton then left the Rainbooms, the lunchroom, and the school, along with his band.
“Who even was that? Why is he here? And WHAT DID HE EVEN MEAN?!” RainbowDash said, still trying to make sense of what happened.
“I’m... just as confused as you are, RD.” Sunset Shimmer stated.
