Tirek, the dark conqueror has used the Rainbow of Darkness on himself in a last ditch effort to conquer Equestria.
Thanks to the combined efforts of the ponies, and the Straw Hat Pirates, Applejack has been rescued and turned back to her former self, and the Elements of Harmony restored.
Now Luffy and the others are preparing to take on Tirek himself.
Luffy, with his body steaming from his Gear Second activation, merely scoffs of his threat, while Sanji and Zoro stood at his side.
"You done gloating, or are you going to fight?" Zoro said, bemused.
"You will regret such insolence, human." Tirek says has he charges up his scepter.
He unleashes a thunderbolt, as Zoro and Sanji jump away, while Luffy, just stood still. The bolt strikes Luffy, as the ponies all watch in horror.
"Oh no!!! LUFFY!" Fluttershy cried out.
"Don't worry," Chopper assured her as he puts a hand on her back. "Trust me, he's ok."
Fluttershy, confused, and concerned looked on, only to see that Luffy was still standing, as if nothing happened, with a smirk on his face.
"WHAT??!!" Tirek yelled in surprise. "You were hit directly by the lightning bolt. Yet you still stand, as if nothing had happened."
"Hee hee," Luffy giggled, as he pulls his cheek. It streches out to abnormal lengths.
"Your electricity won't work on me. I'm a rubberman. I ate the Rubber Rubber Devil Fruit."
"Ah, the legendary cursed Devil's Fruit of the sea. So they do exist." Tirek said to himself.
"No matter, your abilities are still no match for the darkest of magic."
He then shoots a stream of fire out of his mouth at the Straw Hat Captain. This time around Luffy, using his Gear Second super speed, easily evades the attack.
"Gomu Gomu No, Jet Pistol!"
Luffy sends out a strike, and his fist slams right into Tirek's arms, as he blocks the attack.
"Whoa, this guy's pretty strong if he can block my attack like that." Luffy declared, slightly impressed.
"You are a weakling, and are finished. You should never have defied me." Tirek yells as he now turns his attention towards the ponies.
"Look out, he's coming this way!" Twilight Sparkle called to the others, as Tirek fires several laser like beams from his eyes.
The Mane 6 began to run for cover, as Chopper steps up.
"GUARD POINT!"
Chopper transforms into a giant ball, and deflects a number of the blasts, shielding the ponies, but at the same time, he could feel the burning pain from the blasts. He immediately turns back into his tiny brain point form.
"HOT!!! HOT HOT HOT!!!" he yells.
"Chopper, you ok?" Usopp asked.
"I'll be fine, just need to recover."
Meanwhile, Applejack finally gets herself together after her transformation back into a pony.
"How are you feeling dear?" Rarity asked.
"Much better now Rare, Ah'm gonna join in on the fun!" The cowmare declared.
"Again, thank ya all, fer savin' me. An' you guys too," She addresses the rest of the Straw Hats.
"Ah don't think we've been properly introduced, Name's Applejack, best Apple Bucker this side of ole' Equestria!"
"Well, nice to meet you and all..." Sanji said as he jumps away from another one of Tirek's blasts, "But we're kinda busy."
Sanji, using his sky walk technique, runs up in mid air to Tirek's head region, still with his glowing leg from Diable Jamble, unleashes a counter attack.
"Bien Cuit: Grill Shot !"
Sanji delivers a heavy blow, as if his leg was on fire, To Tirek, as the giant Centaur blocks again, but it leaves a massive burn mark on his right forearm.
"GYYYAAAAAA!" He howls in pain.
"I will make you regret that, little man!" Tirek shouts, as he takes a swing at Sanji, who is swatted down to the ground.
"SANJI!" Chopper yells, as he runs up to check on him.
"I'm fine," Sanji says, as he gets up casually, as if nothing had happened.
"Whoa, What kinda guy just gets up from a poundin' like that, and brushes it off like nuthin'?" Applejack said, amazed at how tough the pirate cook is.
"Someone who's been through Hell, and back." Sanji said, reliving his moments where he was stuck on the Okama Island. He shudders a bit.
"Nice try Pervert Cook, but now it's my turn." Zoro said, as he ties his green bandanna on his head.
He then, with two swords drawn in each hand, and a third, clenched in his teeth flies up to Tirek, and unleashes his bladed fury.
"Oni Giri, DEMON SLASH!"
Tirek was able to parry with his scepter, and they begin to battle one another with their respective weapons.
While Zoro and Tirek duel, Sanji, and Luffy also launch their own attacks.
"Poêle à Frire: Spectre" Sanji unleashes a barrage of flaming kicks.
"Gomu Gomu No, Jet GATTLING!" Luffy also releases a flurry of punches.
Tirek spins his scepter like a shield, attempting to block the attacks, most were deflected, but some landed on his chest, and he begins to back away.
"Now's our chance." Twilight said to the rest of the Mane 6, "With Luffy and his friends keeping Tirek busy, We can now use the Elements to finally bring him down, and end all of this madness."
The rest of the ponies agree, and they begin to prepare for the finishing blow.
However, a number of undefeated lizard troops begin to advance towards the ponies.
"Looks like we got company!" Rainbow Dash yells, as the ponies stand ready.
"Don't worry, we got you covered." Franky said as he raises his right arm.
"STRONG RIGHT!" His fist shoots out and slams into several lizard troops, then using the chain at the end of his hand, retracts it back into his socket.
As the rest of the lizard troops converge, Franky locks his left arm, and points it at them.
"Weapons Left!"
Franky fires a barrage of bullet like shrapnel at the remaining troops, knocking them all out.
"This guy's really awesome" Apple Bloom says, now with the other Cutie Mark Crusaders, aboard the Sunny.
He's like some cool robot!" The young apple filly said.
"No way!" Sweetie Belle said, "The Skeleton guy is even cooler. He can use music as a weapon, and runs really fast, maybe even faster than Rainbow Dash!"
"Nuh Uh" Scootaloo interrupted, "No pony's faster than Rainbow Dash, and besides, the long nosed guy with the slingshot is the coolest human. There isn't a target he can't hit!"
"The robot!"
"The Skeleton!"
"No, The sniper!"
As the three fillies argue over who is the best human, the battle continued to rage on.
The six remaining dragons began to advance on the Mane 6 and Straw Hats.
"Big Macintosh Apple! Ya gotta remember me, Ah'm yer sister, Applejack!" She pleaded with her transformed brother.
But it seemed like no use.
"What do we do?" Fluttershy asked, "They're our friends who have been turned into monsters. We can't hurt them."
"Spike please. Remember who you are, remember who I am.... You're family to me...... I love you!"
The giant transformed dragon only roared, and let out a stream of fire at the purple unicorn.
"Gust Sword!"
Nami unleashes a powerful wind, that blows the flame away before it could roast Twilight alive.
"Eyes forward kid." She said, as Twilight comes back to her senses.
"Thanks for saving me, but I can't believe Spike just tried to fry me."
"He's not Spike, at least not anymore." A voice said from behind.
It was Scorpan, he had regained conciousness, but was limping towards the others, it was clear he was badly injured.
"Scorpan, let me take a look." Chopper said as he examines him. "Keep those goons away while I treat him."
"You got it," Usopp says as the Big Mac Dragon converges on the ponies and pirates.
"Pop Green Star: Bamboo Javelin!"
Usopp fires a shot at the Big Macintosh Dragon, the pop green explodes, and turns into sticks of sharp bamboo, as it rains on the dragon, who quickly withdraws.
"Storm Cloud Rod"
Nami unleashes a number of bubbles from her clima-tact, each one containing a storm cloud. The bubbles pop, and each of the clouds are released and attach to each other. Forming a cloud like whip, she unleashes it on the transformed Spike. The electricity knocks him unconscious.
"Don't Worry," Nami said to Twilight and the other ponies, "He'll be ok."
"Neat trick!" Rainbow Dash said, as she sees this, "I got one of my own."
Rainbow flies into the sky, as the transformed Derpy and Cheerilee try to intercept her in the air.
Rainbow Dash then suddenly releases a burst of speed, and a shockwave of rainbows blows them out of the sky, sending them crashing into the ground and knocking them out.
"The Sonic Rainboom, it never fails."
"WHAO THAT WAS AWESOME!" Franky, Usopp, and Chopper yell out in unison, their eyes shining like stars.
"A cool rainbow explosion!" Chopper gleefully shouted.
"SUUUUPPPPEEERRR!!!" Franky shouted out.
The transformed Big Macintosh, Carrot Top, and Vinyl Scratch attempt to attack.
"Ah'm sorry big brother, but I do this cause I love ya."
Applejack jumps onto her brother's back.
"YEE-HAAH!"
She rides the back of the dragon like a rodeo steed. Big Macintosh tries to buck her off, but the cowmare's skill from previous rodeos made her unshakable.
"NOW PINKIE PIE!"
"Okie Dokie Lokie!" Pinkie reponded, as she throws a number of banana peels under Mac's feet.
The dragon slips, and Applejack immediately jumps off, and hogties him in record time.
"My turn.... Usopp POUND!" Usopp uses a hammer, and knocks Big Macintosh out cold.
"Sorry I had to hurt him like that, he must be someone important to you."
"He's mah brother. And Ah forgive you, it's fer his own good. When this is over, We gotta find a way to turn him back."
As Vinyl Scratch and Carrot Top continue the assault by shooting jets of fire at the rest of the pirates and ponies, Brook begins to play his violin. Vinyl stops as soon as she hears the music start.
"Yes, that's right. Let the melody soothe you."
He continues to play...
"Party Music!"
Vinyl now, completely drowned in the melody of Brook's music begins to calm down.
However, she quickly comes back to her senses, and tries to attack the skeleton.
"Ah, I've already struck you."
The transformed DJ pony looks at him in confusion.
"Quinto Tierce Fantasia!" Brook sheaths his cane sword.
Vinyl suddenly feels a sharp pain, and falls to the ground. Defeated.
All that's left now, is the Carrot Top dragon, as she attempts to make another swoop to attack.
Scorpan seeing this attempts to fly up, but Chopper holds him down.
"You're not fully healed, you don't stand a chance."
"I understand doctor, but I can't just sit here and do nothing." Scorpan replied.
"Allow me." Nico Robin said, as she crosses her arms in front of her and closes her eyes.
"Mil Fleur"
Suddenly, what seems like thousands of arms sprout from the ground. They seem to combine into two larger appendages, and soon form into two giant pairs of arms from the ground.
"Gigantesco Mano..... Grab!"
The two giant hands grab the Carrot Top dragon, as it struggles to get free.
"SLAP"
One of the hands then begins to slap the dragon repeatedly, until it loses conciousness.
"Amazing, so this is the power of the Devil Fruit." Scorpan watches in awe.
"I know," Twilight added, "I have so many questions. I wish to learn everything about them."
"So now that the bad guys have been taken care of," Fluttershy said, "Do we use the Elements to stop Tirek now?"
"Indeed Fluttershy," Twilight answered, "Let's get to it!"
As the "Monster Trio" Continued to do battle with the dark demon centaur, Tirek summons a giant fireball with his scepter, and fires it at the pirates.
Zoro jumps forward, and slices the fireball, and it extinguishes. Sanji releases another massive flaming kick with his firery leg, as Tirek is struck in the shoulder. Luffy jumps up and unleashes another jet pistol, right into the centaurs neck.
"We're not doing enough damage." Sanji said.
"That's because your kicks are too weak Pervert Cook."
"Shut your mouth Moss Head."
"Make Me!"
"Hey, Zoro, Sanji, you can't just kick and slice him!" Luffy yelled, as he prepares another attack, only to be swatted aside by Tirek's scepter.
"Gah, that actually hurt. This guy's tougher than I thought." Luffy said to himself.
"My dark magic is more than enough power to defeat your abilites. No Devil Fruit Power can withstand the Rainbow of Darkness!" Tirek gloated as he points his scepter at Luffy.
"That little toy of yours has caused us enough trouble." Zoro said, as he jumps at the demon.
With his swords in play, he positions himself for one of his strongest strikes.
"Purgatory...... ONI GIRI SLASH!"
With a massive flurry of bladed slashes, he strikes at the Centaur.
"You missed, swordsman." Tirek taunted.
"Did I?" Zoro answered.
Suddenly, the scepter in Tirek's hand falls apart, and crumbles into pieces.
"MY SCEPTER! You Fool! Do you have ANY idea of what you have done?!"
Zoro gives a grin.
Tirek, now infuriated, channels dark magic through his hands. He began throwing flaming fireballs at the pirates.
The trio jump, dodge, and run to avoid being hit.
However, one of the explosions got too close to Luffy, and it sends him flying, and knocks him into the side of Carousel Boutique.
Luffy is knocked out of his Second Gear by the impact.
He gets back up as Sanji and Zoro converge to his side and take defensive stances.
"So tell me human, why? Why do you defy me? This matter never concerned you from the beginning. I will rule this land, or destroy it if the ponies reject my rein."
"I won't let you." Luffy said in defiance, "This may not be my home, but the ponies are important to Chopper, my friend, and they in turn are also my friends. I will PROTECT the Ponies, and you will not DESTROY their home!"
"You? Protect them? What a pointless joke." Tirek taunted. "You'll sooner be ground into dust."
Tirek then advances and prepares for another attack.
"Look at you. None of you have even remotely did any damage on me. You are WEAK!"
"Then I guess I'll just have to hit you even HARDER!" Luffy yells. "GEAR SECOND...... ARAMAMENT!"
Luffy pumps his muscles again, and activates his Gear Second once more, except his right arm begins to darken in color.
His right fist has become almost metallic. Then it appears to burst into flames.
Luffy winds up for a blow as he jumps towards Tirek.
"You fool, no physical attack can ever defeat me!"
"We'll see about that." Luffy yells
Zoro and Sanji look on intently,
"He's in for it now." Sanji said, as he puffs on his cigarette.
As Luffy and Tirek are about to collide, the Straw Hat Captain unleashes one of his most powerful attack.
"Gomu Gomu No...... RED HAWK!"
The flaming fist plows into the Demon Centaurs chest, as flames protrude out of his back.
Tirek falls over, and begins coughing.
"Hmph, was there any doubt?" Zoro said with a smirk.
"Impossible.... I cannot, WILL NOT be beaten by pirate scum!"
Tirek begins to chant.
"What's he doing?" Luffy wondered.
As Tirek continues to chant, he starts glowing. Suddenly, the wound on Tirek's chest seemed to heal instantly, and he gets back onto his feet.
"HUH? NO WAY!" Luffy shouted, as Zoro and Sanji also look on in shock.
"A healing spell, granted I can only use it once every two hours, it's more than enough for me to destroy you."
Tirek then turns his attention towards the others, and also sees the Thousand Sunny.
"What was it you said? You destoyed my treasure? Then I'll destroy yours..... YOUR SHIP!"
Tirek then gallops towards the heart of Ponyville where the Thousand Sunny rested, and begins to channel dark magic through his hands again.
"NO! He's going after The Sunny, we have to stop him!" Luffy yelled to the swordsman and the cook.
"No he won't!" Zoro yelled as he gives chase.
"I'm on it!" Sanji said as he runs up next to Zoro.
The ponies, and the rest of the Straw Hats look on as Tirek charges towards their direction.
"He's coming this way, we're not ready!" Rainbow Dash yelled.
"Oh no, this is bad, we haven't begun to charge up the Elements, if he attacks us head on, we'll be obliterated." Twilight said.
"YYIIIIIIKES! What do we do?" Usopp asked in a panic.
"Whatever we can, we MUST hold him off." Twilight said to the sniper.
The Mane 6, the Straw Hats, and the Dark Lord Tirek, all in one final climatic clash, for the fate of Equestria, and possibly the rest of the world. The final battle is at hand.
