Rainbow Sentai: Guardians of Harmony

“Yes little pony yes! Keep dancing!!!! Keep entertaining me!”

Hissed Crescendo as she kept Sunset’ at a distance by using Wailing Cadence in its whip form constantly lashing and whipping at the air and ground around Sunset forcing her to have to dodge or block with her sword. The large lashes of her blade left in the ground and trees as the two battled upon the hills of Canterlot Park.

Crescendo whipped the blade at Sunset again and again attempting to catch her off guard however Sunset proved to be quite agile in using both her foot speed and her wings to evade Crescendo’s barrage of attacks however she was finding it difficult to get in any attacks of her own because she couldn’t get close to the Banshee without that ear murdering wail of her sheath constantly keeping her from getting in close enough to do any actual damage.

‘Dammit this isn’t working…and I’m running low on magic…if this keeps up I’m as good as dead and that could only mean the other girls aren’t fairing nearly as well having to deal with those two…’

She thought to herself trying to use her fast thinking to find a solution to her problem. In truth while Sunset knew elemental combat spells all in the realm of fire and energy she’d never gotten a real chance to flex her battle skills while learning under Celestia nor did she ever get a chance to learn how to defend against black magic of this caliber since Celestia always forbid her from going into the dark magic wing of the royal library.

It didn’t make any sense! Her power had been overflowing intensely along with the others before the Banshee showed up and while she knew her harmony magic would drain out over time forcing her to have to recharge it wasn’t supposed to be draining this fast and even then she felt weaker in her new form, as if she was out of sync with herself and her powers and she wasn’t unleashing her full power. Were the Banshee casting some sort of dampening spell?

"Wait a second..."

Looking back on the events since the Banshee arrived she remembered them screaming at them to surprise them, their introduction and then Crescendo put up this barrier to keep outside forces out. The realization finally hit her as she dodged the whip again causing it to peg into a tree and she gracefully landed on one of the blades with the tip of her golden booted foot and jumped high into the air and using her wings she got up high enough and her theory was confirmed as she flew back down to cease the intense screeching and then looked down at Crescendo who was absorbing a red mist through the gem embedded in her neck.

“I finally understand…”

“So at last you get it little pony? Hmph…took you long enough” Cresendo said with a haughty grin as she retracted her whip into its blade form and slugged it over one shoulder as she realized that Sunset had discovered what she’d done.

“This barrier; it runs on the same magic you do and the long it stays up, the more our magic gets drained through a magical sound wave barrier that produces a song of your choosing not only to throw us off…but to DE harmonize us!” Sunset snapped as she felt her magic weakening still glaring hatefully at Crescendo who simply threw her head back and laughed, her sinisterly bubbly laughter echoing loud enough for her to hear even while flying through the air.

“Very good little pony! You always were the clever one weren’t you? Indeed, the more you fight…the more your precious harmony slips away…ordinarily this barrier would cause mass rage and discord between you fools but your light is strong so we have to beat you down first…which is fine by me!” Crescendo snapped as a pair of black devilish wings sprouted from the back of her outfit and she shot into the air after Sunset.

“Thanks fat mouth you just gave me an idea how to turn the tables!” Sunset gripped her sword and raised it to the sky and channeled as much of her energy as she needed and the blade radiated a bright yellow and Sunset closed her eyes.

“SOLAR FLASH!”

A beam of light burst from the blade and blinded Cresendo and made her hiss in pain and snarl at Sunset as the intense light sheered and burned her and her wings causing her to recoil and when she got the stars out of her eyes Sunset was taking off towards her friends and her sisters.

“Tricky little pony! This is more fun! A game of tag hm? YOU’RE ON! READY OR NOT HERE COMES CREE!! HAHAHAHAHAHAHAHAHAH!”

She shouted as she shot after Sunset who flew at breakneck speed with a trail of fire behind her. As she came over the next hillside she found her friends doing battle with Melody and Ballad having already made quick work of the grunts they’d summoned. Twilight and Starlight were trying to combo attack Ballad whom was blocking and deflecting their attacks with her hellish skeleton dual scythes that doubled as high powered demonic pistols and she even had the afterimage of a grim reaper appear at her side to dish out even more attacks and even protect her when need be.

Meanwhile Rainbow Dash, Applejack, Pinkie & Rarity were doing their best to tag down Melody but she gracefully skated around them and using the jet system in her cybernetic like suit she managed to catch them with a variant of surprise attacks like hidden explosive charges and lasers from her hands and chest and her massive axe made it easy for her to block their weapons and its manipulation over ice helped too. Spike in his dragon form was doing his best to shoot fire at the pair of Banshee and protect the stage where Vinyl Scratch was hiding out since she couldn’t escape the barrier but she was exactly the person she needed right now to help them out of this mess.

“Girls!” Sunset shouted to her friends as she joined the fight helping Twilight and Starlight get in a few strikes on Ballad forcing the banshee to jump back.

“Sunny! You ok?!” Twilight asked with heartfelt concern.

“I’m fine Sparky but we’ve got a problem…this barrier is de-harmonizing us!” Sunset said as she put up a small barrier around them along with Twilight and Starlight by combining their magic, luckily she’d asked Shining Armor to lend his powerful shield magic to the matrix otherwise Ballad probably would have busted through it already.

“What?! How is that possible!?” Starlight asked in shock

“It’s a part of musical spell, much more powerful than the one they usually use, they may have changed their names and looks but deep down they are still sirens…and theres only one way to fight sirens…”

“How? Twilight asked”

“With music of course! I forgot you weren’t here for the battle of the bands but I know what we’ve gotta do…can you hold them off? I need to get to Vinyl…time to pump up the volume on our own song for this party…” Sunset said as she opened up the barrier enough for her to get out and make a Beeline for her other friends.

“Good to see your alive Sunset! We could really use your help here!” Rainbow said as she jumped back floating in the air, her wounds healing slowly as she panted in exhaustion. “We’re startin’ to fade here…”

“Don’t worry Dash, I’ve got a plan to-oh shit!”

“Miss me little pony?!” Cresendo hissed as she shot off a sonic scream down at Sunset and the other girls which Sunset tried her best to block with a magical barrier which was helpfully reinforced by Rarity and her magic glyphs.

"I've got your back darling, Pinkie be a dear and handle this heathen!" Rarity shouted

As the barrier held Pinkie ducked and rolled to a new position and turned her hammer back into its grenade launcher form and pumped the handle a few times and target locked on Crescendo. The cylinders in the chamber having switched to ‘Firecracker’

“HAVE A BLAST!” Pinkie shouted as she fired off a grenade that split into smaller ones and they surrounded Crescendo flickered and then exploded in a flurry of confetti and streamers that caused the banshee to howl and shriek as she was then also wrapped up in said streamers and Pinkie laughed.

“Haha all wrapped up nice like a present! Go Sunny! We’ve got this!” Pinkie shouted to Sunset.

Sunset made her way to the stage where Vinyl Scratch was hiding in her compact DJ booth transforming car and seemed to be tinkering with it even in the heat of everything going on and she noticed Sunset.

“Sunset c’mere quick I think I know a way I can help!”

“Me too, how loud can the speakers of your car get?” Sunset asked putting up a shield so they could speak without fear of ambush.

“Loud enough to shake this entire park on a full tank but its batteries are low after we harmonized you, I’ve been trying to divert all extra power to the primary speakers, and this barrier is messing with your grooves big time!”

“I know, it’s draining our magic and taking us out of harmony with each other, we need to resync and fast otherwise this is gonna get real ugly…”

“I’m gonna need Pinkie for this one; she’s the only one with enough exceess energy to pump these to the volume I-“

“You rang?!” Pinkie appeared out of nowhere in typical Pinkie fashion which at this point didn’t surprise Vinyl or Sunset

“Right on cue” they both said.

“Pinks I need you to power up my car with your magic, time to pump this party up the 11…” Vinyl pushed up her shades with a grin.

“Righty-o Scatchy!” Pinkie hopped on top of the car and channeled her magic into it and made it transform into a larger more futuristic high tech version of itself with even more neon lights and ports along the entire thing and Sunset would call out to her friends.

“Girls! Regroup! It’s time to really get this party pumping!”

“Right!”

The girls all regrouped to the stage and the three banshee regrouped together as well, Ballad slicing Crescendo free of her bindings since they only grew tighter the more she struggled.

“Rah these little pests are beginning to test my nerves!” Crescendo hissed.

“Yeah you bitches are really startin’ to urk me!”

“Ditto to that sis! You little cunts are gonna be BEGGING to let us kill you once we get our hands on you!”

“Pft we’ll see about that…time to pump up the party!” Vinyl said with a grin as she turned her transforming car towards the banshee as the Rainbooms stood in front of it, the large subwoofers towering over them. Crescendo, Ballad and Melody all looked at the device and rolled their eyes and scoffed.

“The fuck is that thing?” Ballad sneered

“Looks like big ass subwoofer out of a cheap sci-fi movie to me…”

“And just what do you plan on doing with that…whatever that is?”

“Oh this? Oh it’s nothin’ special…” Vinyl cracked a smirk as she’d been dying to actually use this function of her car since she’d had it installed but it wasn’t exactly street legal to have a giant cannon in your car but at this point she was REALLY glad Pinkie gave her the idea for this.

“JUST MY BASS CANNON!!!”

Vinyl slammed her fist on a large red button and the woofers grew in size and then extended outward looking like the barrels of cannons as they filled with a sparkling energy that was a variant of different colors and the woofers shook and vibrated for the beat to drop and when it did as Vinyl smashed the button a massive sound wave of magical energy blasted forward from the barrels sending the Banshee flying back crashing through the trees and the barrier was now changing colors more befitting of the Rainboom’s and Vinyl Scratches style and a new song played through the sound waves and the girls began to feel reenergized as their amulets lit up and they began to heal much faster, especially Fluttershy whom after fully healing cast a spell that healed the others in a quicker fashion as well. Feeling empowered again the girls looked to one another as the catchy and rather heroic music played around them as if calling them in to battle and this time the tables were turned because now the Rainbooms would be able to fight at full strength. Grinning Sunset would pound a determined fist into her palm.

“Well girls I think it’s about time we show these Banshee’s how to Rainbow rocks…You with me?!”

“LET’S ROCK!!” The girls shouted in unison as they barred their weapons, the Banshee having now come back into the line of sight obviously angry and ready for a fight.

“Looks like we may have underestimated you little brats…that’s good…I was beginning to think this was too easy!” snapped Crescendo.

“Now you bitches are making this interesting!” Ballad sneered

“You struggling will only make it more fun when we finally kill all of you!” Giggled Melody.

“Oh yeah?! Well let’s have another dance and see who’s the last one standing!” Rainbow shouted.

“Your funeral…” the banshee said in unison
