After the Sirens were defeated by Twilight & her friends, the Sirens escaped, shamed of what had occurred! But then one day, they figured out that they can still manipulate others into fighting each other! So, they find musicians that they can easily sink their devious fins into and use them to cause harm to others! And with that chaos, allowed them to restore their power! Finding out about this outrage, Princess Twilight Sparkle began a secret organization, based on music that she hopes to finally find then apprehend these 3 and stop them once & for all! The name of this organization? It's name is...

Saving
Horses
In
Trouble

Or...S.H.I.T for short. All of S.H.I.T.'s agents sent all across Equestria to protect the harmony from the Sirens and their minions of evil music.

You're probably wondering which universe we're in, well, as it turns out, the Sirens snuck back into Equestria, that should clear up some confusion. Anyways...Spike, one of Twilight's top agents/adopted son/#1 Assistant has been assigned a partner on this next mission that may very well mean the end of the Sirens once & for all!

He was walking to the house of said partner and knocked on the door. Vinyl answered.

"Oh, hey Vinyl Scratch, is Octavia ready?"

"Hey Tavi, your date is here!"

"Oh ha ha, go back to your regular canon volume!" Then Octavia appeared. "Good day young dragon, let's roll." Then they were off.

"So, what did you mean by regular canon volume?" Asked Spike.

"Well, the fans will go into a rampage if Jessica Nowack AKA Nowacking isn't the one voicing Vinyl." Octavia replied.

"Oh, that's sorta like how in Episode 100, Derpy's voice actress did the Balddumborat version of Derpy's voice."

"Exactly, though I doubt the brony community knows a lot about Balddumborat unless they watch MLP Tumblr Dubs of Lovestruck Derpy or her I think 1 appearance in Bronies React by ACRacebest the arch nemesis to M.A. Larson."

"Yeah, I guess."

"So, where are we going?"

"Las Pegasus, another Elvis impersonator has been manipulated."

Soon they got to the train station and purchased a private booth for the trip. Both took their own seat as they faced the other.

Spike stared at Octavia.

"What's wrong Spike?"

"N-nothing it's fine."

"Spike, if we are to be partners, we must have trust in the other."

"F-fine! It's just that, I worry sometimes."

"Worry?"

"Yeah, I worry about what'll happen to my partners."

"Why?"

"Well, it happen back when I had my 1st ever mission, I was partnered with Sweetie Belle, it was bad, very bad! Sweetie Belle's singing voice was no match for Tantalizing Taste, his corrupted power was enough to badly damage her! The only reason we survived was because I managed to knock him back into his senses with my piano playing!" Then he closed his eyes! "Every time my eyes close, I can see Rarity, her parents, AB, and Scootaloo's angry faces looking at me, silently saying that I broke my promise to bring her back safe!" That's when he collapsed!

Octavia's eyes widened as she got up form her seat and pulled Spike close to her chest.

"There, there Spike 'Wow, someone so composed as an adult, being able to break down like this.' don't cry, I'm more experienced in music, I should be able to take anything this Elvis impersonator has waiting for us."

"Thank you Octavia, you're so nice."

Octavia smiled and got back on her seat with Spike in her arms as she figured he could use the emotional support.

"So, what are things like now with them?"

"Only one won't forgive me, and refuses to even speak to me..."

"Well, whomever this last one is, let's forgive that one together."

"It's Sweetie Belle's sister, Rarity!"

'Okay, so helping him get forgiveness will be harder than I thought.'

"Ironic since I've always wanted her to return my affections." he let out a bitter chuckle.

"Aww, don't add insult to injury to yourself Spike, anyone 'besides her considering everyone's forgiven you' can't stay mad at you."

"You really mean it?"

"Of course." she smiled.

Soon, they made it to their destination, Las Pegasus.

"Where shall we start?" asked Octavia after they got off the train.

"Hey! That's my Banana!"

"Gimme back my 3DS!"

"Hey punk ass, screw you!"

"I suggest we start with the trail of everyone fighting."

The two of them walked down the path where ponies were in some kind of fight.

"Alright Octavia, begin playing your Cello, I'll play my Keytaur!"

"I thought you played the piano."

"Piano's are too heavy to carry around."

"Good point."

Then as they played, magical sound waves countered the negativity, causing everyone to forgive, forget, and to an extent for some, they even fucked!

"Good Work Octavia."

"I appreciated the fine job you did as well Spike." Spike blushed at the compliment until...

"Honka Honka, what the hay do you 2 think you're doing uh huh huh?"

"It's him!"

"Sir, you have been corrupted by evil, let us help you."

"No way momma! I'm Peter Goodfella, and all's I need, is the sirens!" That's when he began singing, firing sound waves at Spike & Octavia which they countered with sound waves of their own!

"Pour it on!" called Spike moving his claws as fast as he could.

"No! I don't wanna leave the buildaaaaaaaaaaaaaaaaaaaaaaaaaah!" The Impersonator cried as he was sent flying towards a bill board forcing the dark magic out of him!"

"Time after time, you always beat our strongest!" Complained Adagio.

"Yeah, and I will defeat you this time!"

"Hah! Ooh look girls, Spike here has another pretty partner with him!"

"Let's crush her!" Said Aria Blaze!

Then all 3 Sirens began singing while flying around the 2!

"Quick, we gotta find higher ground!"

So they ran into a huge hotel, climbing the steps, until they made it to the top! The Sirens fired evil notes, but the dodge rolled out of the way! Then, Spike & Octavia were back to back!

"Any plans?" asked Spike.

"Yes, actually! I learned how to use my Cello as a melee weapon back in Cranky & Matilda's wedding day."

"So? Also, who were you going to fight?"

"D-doesn't matter, what does, is that you should charge up an attack, and I'll smack the orb of stored energy into them!"

"Alright."

Spike then played fast, and once the orb was as big as Octvia's head, she smacked it with her Cello!

"Ooh, shiny!" Said Sonata Dusk.

*BOOM!*

"Ow..." Said the dazed Sonata.

"Dammit Sonata, I thought we already taught you to stop touching every last shiny object you see!" Said Adagio.

"You did, I didn't."

"Yeah, you were fooling around with that stupid boy."

While they bickered, Spike got another orb all ready. Octavia smacked it once again!

"Hey, you're just jealousy that I'm dating a badass!"

"Yeah, a badass who steals his mom's make-up!"

"Hey, at least my guy isn't a tool like your dild..." *BOOM!*

The energy orb engulfed the sirens an sent them flying.

"Yeah! We got them!"

"You think so don't you?" Said all 3 in a dark tone!

"Huh?!"

That's when all 3 of them flew to ground level! All 3 then fused! The bright light flashed! That's when...

"Whoa..."

"What had appeared was not the sirens anymore! Oh, no! It was much, much worse!

What stood before them, was a giant golden, twin tailed, 3 headed, arm less dragon!

"Are you seriously kidding me?!"

"What's wrong Spike? Do you know this creature?"

"Yeah! That's..K...K..."

"Out with it!"

"That's King Ghidorah! All this time, the Sirens were Ghidorah! We're doomed!"

"Oh come now. There must be some contingency plan you have in store."

"I do...but, it all depends if you want to do it."

"For someone as amazing as you, I'll do anything!"

"Well...I can summon the king of the monsters himself if we play this sheet music." Then Spike handed her the sheet music.

"Let's do it."

"Wait, are you willing to live with the fact that you summoned an unstoppable force of nature powerful enough to not let even the princesses, Discord, and the mane 6 combined get in it's way?!"

Then she kissed him. "Well then, guess we'll be making great music together in the afterlife."

Then they played the song, summoning Godzilla to destroy Ghidorah!

'SHIT!' thought the sirens as Godzilla charged and slammed into them.

Godzilla then ended Ghidorah as he blasted them to nothing as he used both his atomic breath & red spiral ray!

"We did it Spike!" Octavia said while hugging Spike.

"Yeah, but now everyone will die..." Said Spike, losing hope.

"Don't cry Spike, we succeeded at the mission." Then she hugged him closer as Godzilla turned around and destroyed the entire building they were on!

Later...

"What the?" Octavia asked herself.

"I'm here, and yet there's me up there with that red headed Alicorn?"

"Where are we?" asked Octavia.

"You're in the afterlife, and this here is my husband/grandson!"

"Ew!" They both replied.

"Oh, don't you contradict your love of older mares grandson!"

Spike looked away as Octavia looked at him in surprise. "Well, I do go for older mares, BUT THIS VERSION HAS NO INTEREST IN GRANNY AGED MARES!!!"

"Then what is your type of mare?" asked Octavia.

"Pure & elegant mares, such as Rarity, such as Fleur De Lis, despite her being with Fancy Pants..." Then he looked at Octavia. "And even mares such as...you..."

Octavia couldn't help but blush at the compliment.

Spike then took Octavia by the front hooves.

"Well, since the world is ending...mind throwing us a wedding...grandma?"

"Why of course, I love throwing your wedding! I remember when I threw a wedding for this one Spike & his Siren harem!"

"Wow Spike, the tastes of these other versions of you sure know how to surprise me."

"Yup." nodded the dragon.

So Spike & Octavia watched as Godzilla got all the guests ready for their wedding, drinking smoothies while leaning heads together.

"Even though smiling while watching this is messed-up, I love being here with you Octavia."

"I feel the same way about you as well Spike." Then Octavia put a hoof around Spike's back to hold him closer.
