Sonic, Shadow and the Equestria Girls

Chapter 6:Harmonic Chaos

The principal and vice principal both entered the stage.

"Well, we have had a lot of great acts tonight, but now the final round has been decided," celestia said.

"The two groups that will move on to the finals are…" Luna continued, "The Rainbooms and the Dazzlings!"

"What?" literally everyone said at the same time.

"How, but we…" twilight started before getting elbowed in the gut by rainbow to shut up.

"We look forward to see you all tonight at the final round," celestia finished.

Sonic, shadow and sunset all held back to talk to each other.

"The dazzlings told them who to put next, this all part of their plan,"

"Okay, so their plan goes on, but why have the rainbooms compete still?" shadow asked.

"I don't know," sunset said, "unless they know about the magic."

"How would they, we've been keeping a lid on it?" shadow questioned.

"Well, they also said I have magic, magic that somehow adagio got," sonic said remembering adagio's discolored eyes and pendant, "what if they want to take their magic too?"

"Well, I don't know anything about any magic you have, but having three different kinds of magic at their disposal would be a serious threat," sunset said, "if that's the case, then we can't let them in while the rainbooms practice."

"So we've been demoted to security, of course," shadow sighed.

"It'll all be over soon, bro," sonic said.

Later that day the rainbooms were rehearsing at the stage for the final round. Sonic, shadow and sunset were also there making sure the dazzlings didn't come anywhere near them.

"Check, 1, 2…" rainbow dash said tapping the mic.

"You know it just doesn't make any sense," fluttershy said, "we were awful last round, does anyone else find it strange we're the ones in the finals?"

"Very strange," trixie said as her band came up to them.

"What are you doing here, trixie? Pretty sure the losers sit in the cheap seats," rainbow dash mocked.

Trixie scowled, "the great and powerful trixie is the most talented girl at canterlot high! It is I who deserve to be in the finals, and I shall not be denied!"

She snapped her fingers and one of her bandmates pulled a lever causing trap door underneath, the rainbooms, sonic, shadow and sunset. What they didn't realise was spike didn't fall through and saw the whole thing.

"See you never rainbooms," trixie laughed, "oh, and sonic nothing personal, you were just in close proximity to them, so you're down there by accident."

The dazzlings looked at this display and laughed.

"Looks like someone was willing to give the rainbooms a shove in the wrong direction," adagio said.

"But she didn't shove them she pulled a lever," sonata said confused.

"Go back to sleep, sonata," aria said face palming.

Later that night the final round began. Trixie had made up the excuse that the rainbooms were out sick and couldn't make it, which in the principal's hypnotised state, they got away with.

Underneath the stage sonic, shadow, sunset and the rainbooms were still trapped. Rainbow dash kept slamming into the door, trying to break it down.

"Oh, give it up already, dash, you've been try'en that for hours!" Applejack yelled.

"Maybe it doesn't even matter that were trapped down here," twilight sighed, "I don't even think the counter spell would of even worked."

"Of course it would of, twilight," Applejack said before shifting her glance towards rainbow dash, "Assumin' a certain band member didn't try to hog the spotlight the whole time we were tryin' to play it!"

"Hey, if you wanna tell twilight that she's getting a little too caught up in being the new leader of the band, you don't need to be so cryptic about it!" rainbow dash said.

"Are we really doing this?" sonic asked.

Rarity ignored this and yelled, "She's talking about you, Rainbow dash!"

"Apparently we are," sunset sighed.

"Me? I'm just trying to make sure my band rocks!" rainbow dash defended herself.

"OUR BAND!" A.J., pinkie, rarity, and fluttershy all yelled.

"It might of been yur idea to start the band, but it doesn't make it your band!" Applejack yelled.

"Well I'm the one who writes all the songs!" rainbow shot back.

"I write songs, you just never let us play any of them!" Fluttershy yelled.

"I had the perfect outfits for us to where," rarity complained.

"Again with the costumes? No one cares what were wearing!" applejack yelled.

"I care, Applejack!" rarity yelled back, "so sorry if I enjoy making a creative contribution to the group!"

"Hey anyone remember fun, here's a hint, it's the exact opposite of being in the rainbooms!" Pinkie pie yelled.

The five of them fell into an all out argument, negative energy pouring out of them and rising to the ceiling. Above them the dazzlings felt and absorbed this energy sending a chill up aria and Sonata's spines, while adagio took a pleasure in devouring it.

Trixie's band had just finished and were walking off stage.

"Try to beat that!" trixie said cockily.

"Oh, I don't know if we can," adagio said sarcastically before laughing.

The three walked on stage and began singing. Below them the rainbooms continued to argue, eventually sonic decided he'd had enough, "Everybody, Chill!"

This got all five of them to stop arguing and turn their attention towards sonic.

"Huh, that actually worked better than I thought," sonic said.

"Don't you guys see, this is what they've been after the entire time!" sunset said, "they're feeding off the magic inside of you."

"By how can they be doing that? Our magic is the magic of friendship!" applejack questioned.

" Ever since you started this band, you've been letting little things get to you. I never said anything 'cause I didn't feel like it was my place. Not when I was so new to this whole "friendship" thing. I still have a lot to learn. But I do know that if you don't work out even the smallest problems right at the start, the magic of friendship can be turned into something else," sunset explained.

"Something darker," sonic added.

"Something that can be used against you," shadow finished.

"I can't believe all this tension was happening right under my nose and I didn't realize it. I'm supposed to be the one with all the answers. And all I've done since I got here is let you down," twilight said.

"I don't think anyone is supposed to have all the answers. But you can count on your friends to help you find them," sunset said making her perk-up.

"You already have," twilight said.

"Alright, let's figure a way out of here!" sonic said.

The 9 of them all rammed the door at the same time. The door was unlocked from the other side and it opened letting all of them hit the floor. A familiar purple and green canine came up.

"Spike!" twilight exclaimed.

"Sorry it took so long, had to find someone who wasn't under the dazzlings' spell," the dog replied. A girl with white skin, spiky blue and cyan hair, pink tinted sunglasses, cyan headphones, and a white jacket-dress with purple tights and blue sneakers.

"Vinyl?" rainbow dash asked, "why aren't you under the spell?"

"Never take my headphones off," vinyl shrugged.

"Come on y'all, now's our chance to show we still got the magic of friendship inside of us," applejack spoke up.

"And there's only one way to do that," twilight said.

"We're getting the band back together!" pinkie pie exclaimed.

"We're getting our band back together, and I think we have room for two more," rainbow dash said eyeing sonic and shadow.

"Which version of the counterspell do we play?" rarity asked.

"Honestly, I don't think it matters what song we play, as long as we play it together," twilight said.

"I know just the song," dash said, to which fluttershy druped a bit, "fluttershy wrote a really great one."

"Were about to save the world, I think we should do it in style," applejack said which was rarity's que to grab a ton of outfits, "I thought you'd never ask!"

The dazzlings at the moment were in the middle of their final song.

(do I even need to say it?)

Adagio: Welcome to the show…

Sonata and aria: ah ah ah ah,

Adagio: were here to let you know…

Sonata and aria: ah ah ah ah,

Adagio: our time is now…

All: your time is running out

Meanwhile at the top of the hill the rainbooms were prepared to rock the entire school out of the trance, each of them wearing a multi-colored outfit.

"How are we supposed to play over them from up here?" rainbow dash asked. They suddenly heard a car horn sound behind them. They turned to see vinyl pulling up her car. She pressed a button and the car started to shift.

"What is that?" shadow asked confused.

"Oh, nothing too special, it's just…" vinyl started as the car finished transforming into a DJ booth, "My Bass Cannon!"

"Rad!" sonic exclaimed.

The dazzlings below continued their song, everyone being dragged deeper into the trance.

Dazzlings: Feel the wave of sound,(oh ah oh) as it crashes down,(ah, ah) you can't turn away, we'll make you wanna stay! We will be adored, tell us that you want us, we won't be ignored, it's time for our reward, now you need us come and heed us, nothing will stop us now!

While they were singing, aria and sonata ponied up, they expected adagio to do the same but something else happened. While she did get the ears and tail like the others, her skin and hair turned a dark purple, and her hair stood on end. her eyes became a deep red with no pupils, and she sprouted giant bat wings. Her outfit changed to a golden color and became for riged, when the transformation was complete, a dark voice yelled, "Armageddon Adagio." This transformation shocked the other two dazzlings but they held their tongues.

At that moment there music was instantly drowned out by other music.

Rainbooms: Oh, oh, oh, oh, I've got the music in me! Oh, oh, oh oh...

twilight:Don't need to hear a crowd, cheering out my name!

Sonic: I didn't come here seeking infamy or fame!

Rainbooms: the one and only thing, that i am here to bring, is music, is the music, is the music in my soul! Gonna break out(OUT!) set myself free, yeah! Let it all go(GO!) just let it be, yeah! Find the music in your heart, let the music make you start, to set, yourself, apart!

They all ponied up with the exceptions of sonic, shadow and vinyl. Armageddon Adagio took this as a challenge, "so the rainbooms want to make this into a real battle of the bands, then lets battle!"

Dazzlings: What we have in store(ah, uh) All we want and more!(ah, uh) we will break on threw, now it's time to finish you!

The other two dazzlings eyes turned red and from there pendants came giant, spirit-like horse- shark hybrids, one blue, one purple. The creatures began to circle the rainbooms as adagio flew up above them. Pinkie did a drum solo knocking the three of them back. Rarity played some notes on her keyboard causing a hurricane of blue diamonds to be flung in the direction of aria's familiar, Fluttershy shook her tambourine causing a swarm of butterflies to attack sonata's, and finally twilight sung abit which solidified in mini-stars that were thrown at adagio, unfortunatly adagio countered with her own musical attack. The three sirens focused their attacks on the group, the sound making it impossible to stand, let alone counter.

One sound wave knocked the microphone out of twilights hand. It fell at Sunset's feet and she picked it up. Sonic noticed this and called to her, "Sunset! We need you!"

Sunset took a deep breath, and then walked in front of the group, taking of her leather jacket. Sonic struggled to her side and began playing some notes on his guitar while sunset sang.

Sunset: You're never gonna bring me down! You're never gonna break this part of me! My friends are here to bring me round, not singing just for popularity!

Sonic and sunset: we're here to let you know, that we won't let it go, our music is a bomb and its about to blow! And you can try to fight, but we have got the light, of friendship on our side!

Sunset started radiating yellow energy, as sonic's pendant radiated in blue. The two gained ears and tails, while sonic gained wings. The two's energy combined creating a shock wave knocking the three sirens back and destroying their familiars. Aria quickly realised what would happen next and jumped off the stage.

"Where are you going?" sonata yelled.

"She who fights and runs away, lives to fight another day!" aria said making a run for it.

The rainbooms: got the music in our hearts, were gonna blow this thing apart! And together we will never be afraid of the dark.

Energy from each of the rainbooms began to flow into sonic's pendant causing him to be engulfed in a rainbow light. Armageddon adagio prepared to attack but was shocked when sonic emerged from the light. His hair and clothes had turned a bright gold with blue streaks, his eyes were completely white, and he was radiating in rainbow light. A god like voice exclaimed, "Super Sonic!" when the transformation was complete. As the rainbooms ended the song, the now proclaimed "Super Sonic" charged a final attack, "Harmonic, Chaos Blast!" a rainbow beam was shot in the direction of adagio, who tried to counter, but the blast overpowered her voice, the blast destroyed her pendant reverting her to her normal human body, and she was knocked back to the stage landing on sonata.

As sonic landed, he returned to normal as everyone ponied down. When he landed sunset ran up to and excitedly hugged him.

"Sonic, that was amazing! how did you do that?" she questioned.

"To be honest, I don't really know, it just felt like everyone's energy was backing me up, especially yours," sonic said. The two just stared into each others' for a moment then noticed adagio regain consciousness.

She got up and noticed her pendant in pieces on the ground, but she tried to sing anyway, "Wee wiill be ado..red, tell us.. That…" but it was an off-key mess that the crowd booed. She ran off stage and right into sonic.

"Hey, big blue, when I said that I didn't care about you, that… was just the negative energy talking," she said trying to sound convincing.

"Adagio, you're lucky that even if I called the cops they'd never believe it, if anything, you deserve to have your voice taken, and to have the entire school hate you, so beat it," sonic sneered, "just take it as, bad break up."

Adagio jaw dropped than just ran for it, soon being followed by sonata. Sunset came up and examined the remains of the pendants.

"Looks like this was why their pendants were so important to them, without them, they're just three harmless, teenage girls," sunset said.

"Two," shadow corrected, "we only saw two leave the stage, and the remains of only two of the pendants, one must have realised winning wasn't an option and ran for it."

"Well, if she was smart enough to leave before she lost, we likely won't be seeing her again," rainbow dash said.

"I suppose," shadow said before pinkie pie shot up behind him, "aw yeah, shady! Rainbooms rule, dazzlings drool!"

"Stop calling me shady!" shadow yelled.

The group all exchanged laughs, and then rainbow dash said, "hey sunset, since twi has to leave soon, we could use a great singer to help fluttershy on back-up vocals."

Sunset smiled for a bit, then grabbed a guitar and did a solo she had clearly been practicing, she then stopped and said, "I also play guitar."

"Uh, we'll see," rainbow said dumbfounded.

The group realised that the crowd was cheering for an encore to their performance.

"I don't see why not?" sonic said grabbing his guitar.

While the rainbooms played, a cloaked figure watched from the shadows thinking to himself, "interesting, sonic was able to use the positive energy from those girls to go super with only one emerald, if i were to tap into this power, my goal would come easy. Enjoy your victory, hedgehog, it might be your last."
