Princess Luna, Princess Cadence with her husband Shining Armor and Eddy's brother were waiting patiently around the blue and black portal for Discord's return. The can of spinach that Eddy's brother have provided them to fully recover their strengths and magic while reducing their fatigue.

"What's taking Discord so long!? He knows that Twilight and the others need our help as soon as possible!" Shining Armor said, beginning to grow impatient.

"Shining Armor, do understand that this is a tremendous task that Discord took upon himself. Even as the Lord of Chaos, it would not be easy to figure his way around an entirely different world." Luna tried to reason with the Prince of the Crystal Empire as she looked back at the portal "Especially one that is far out of our dimensional plane." she claimed.

Suddenly the ponies could see a rippled in the portal and the Draconequus in questioned have reemerged from it. The four ponies then ran up and gathered around him in worry.

"Discord, how was it? Did you find them?" Cadence asked, hoping for a yes.

The being of chaos scratches his head with his eagle claw "Well the ride there was certainly bumpier than I imagined, but I did find our solution." he said.

"And what did they say?" Eddy's brother questioned concernedly.

Discord gave him a smug look as he steps back and show the portal to them. Several more ripples appeared around the portal as the ponies could make out five silhouettes inside it. The two unicorns and two Alicorns both eyes widened and smiled optimistically as the five silhouettes stepped out of the portals and appeared before them as they all yelled one familiar phrase.

"HENSHIN!"

Back on the Exodus ship, the Riders and stallions turned around to see where the Kaijin mares once were. Once the smoke and dust have settled, the five original bearers of the Elements seemed to gently floated down and rested quietly on the hull of the ship. Their original appearances have restored along with their cutie marks, there are no signs of any Kaijin corruption on them and all five of them appeared to be resting peacefully.

Each of the Riders quickly and carefully picked up the mares before them as they and the Colt-de-sac gang rushed over to where Eddward, Twilight and Spike were. They gently placed the five ponies down before Twilight as the Princess slowly bent down and gently nuzzled each of her friends as Spike too tried to rouse them awake.

"Miss Fluttershy, please be alright." Prince Eddward said with grief in his voice trying to gently shook Fluttershy, sure they only knew each other during their time on the Crystal Empire, but he knew in his heart that Fluttershy was the right kind of mare for him.

"Pinkie! Please be okay!" Ed pleaded as he slowly shake Pinkie without being to forceful on her.

Suddenly, the five mares began to moan and groan, not before long their eyes started to flutter open. Applejack was the first to regain her senses, she looked around from left and right to see the stallions and the Riders. Rarity was the next one, her hooves going to her head as she touched her mane and felt a sense of relief when she confirmed it wasn't a literal nest of serpents. Fluttershy awakens while remained hidden behind her long bangs and cried softly, Pinkie Pie woke up next and Rainbow Dash was to last one to regain consciousness.

"Girls...you're all alright!" Twilight said with pure joy.

"Thank Celestia!" Spike exclaimed in relief.

"Pinkie! You're okay!" Ed smiled as he hugged the pink mare tightly.

"Miss Fluttershy, you are a sight for sore eyes." Eddward said with happiness, but he noticed her fearful response "Miss Fluttershy, what's wrong?" he gently asked.

"W-We-We...w-w-were s-so s-sorry." Fluttershy said in a pained voice before looking toward Twilight "I-I-I h-h-hurt you Twilight, I al-al-almost k-k-killed you." she stuttered and shivered while hiding behind her mane.

Applejack nodded "She's right, we couldn't stopped ourselves. We're all mighty sorry." she said in shame.

Twilight grimaced, there was no denying that that was a fact. Twilight had come as close to death's door than she would've liked. "But I'm okay now, I'm alive thanks to them." she said as she gestured to the Colt-de-sac stallions and the Kamen Riders.

"It still doesn't excuse for what we did! We tried so hard to stop it! But we couldn't…" Rainbow Dash stated frustrated.

"I took away your smiles…I'm supposed to bring smiles to ponies, not take them away." said Pinkie as she starts to sniffle.

But Ed hugged her tighter "Pinkie! It's okay, you're back now! That's all that matters!" he said happily.

"You're right buddy!" Fourze agreed as he looked towards Pinkie Pie "This wasn't your fault. It was those Foundation X bastards that are to blame." he stated.

"Why else all of you shed in tears when you all saw that she was hurt and when she was alive?" OOO's pointed out as well.

"Aye aye! These monstrous menaces are the ones that deserved to be guilty!" Rolf agreed with the Medal Rider.

The five mares recalled that moment, when they heard Twilight was alive, they felt such a sense of joy and relief that it was strong enough to manifest physically even in their Kaijin forms.

Twilight moved closer to her friends "Not once did I ever think you were lost. I knew we just had to try to bring you back with the Elements, Eddward, his friends and these six heroes, have helped us in doing that, and now I have my best friends back."

The girls all broke into sobs as they lunged for the princess and hugged her tightly, uttering apology after apology. While the six stallions and five Riders (six if Philip counts) merely looked on and smiled at the six pony friends reunited.

"UNACCEPTABLE!" the furious Retsu yelled, getting the Rider's, ponies and dragon's attention to him "THIS IS ABSOLUTELY UNACCEPTABLE! All of my hard work and dedication are now ruined because of all of YOU and that damn MAGIC!" The mad scientist said with pure rage.

"Oi! Don't start spouting crap right now Retsu! You're about to get what's coming for you in a second." Double said with Shotaro's voice with his left eye flashing as he raised his double edge sword.

But the mad scientist began to cackle instead "It can't be helped Rider! It can't be helped! All scientific breakthroughs required radical and drastic measures!..." he said as he reached into his coat pocket and pulled out a syringe with an unknown substance in it "EVEN IF IT MEANS USING ONE'S SELF AS A GUINEA PIG!" Retsu took the syringe and plunged it into the vein at the crook of his right arm.

The Kamen Rider's entered a defensive stance, unsure if it was wise to attack. Retsu's eyes glowed bright green as his body underwent a horrifying transformation. His skin became gelatinous, and completely green colored. At the core of his being was a green sphere, and soon the green light sphere created a humanoid body. The gelatin substance began to reform around that core, taking on a different shape. In a flash of light, the body solidified, and the heroes beheld Retsu's new experiment.

This Kaijin was unlike anything the Riders had seen before, it had a silver insectoid exoskeleton. Upon its chest were five embedded crystals which formed a star pattern, ranging from red, blue, yellow, navy, and purple. On its head was a crest in the shape of two large pincers like that of a stag beetle, where its eyes would be was a visor that had a compounded pattern on it. Retsu's hands had become armored claws, and around the elbows were elongated blade-like protrusions that gleamed in the light that he generated. All throughout his body were intricate engravings that pulsated with yellow energy, all of which led right back to the center of his chest where the gems rested.

Retsu looked upon his newly transformed body, examining his transformed flesh and bone, and relishing in the feeling of the immense power that now flowed through his body "Hahahahahahahahahaha! AHAHAHAHAHAHAHAHAHAHA!" The psychotic scientist let out a mad laugh "Such incredible power! I should have done this from the start! HAHAHAHAHAHAHA!" he exclaimed in pure delight while laughing diabolically again.

"Anypony get the feeling that this just went from bad to worst?" Duncan asked with a deeply disturbed tone.

"Eeyup." Applejack answered in agreement.

"I'm with ya." Gaim added with the mohawk stallion and the cowpony's respond.

Without warning Retsu disappeared, causing our heroes to be on guard. However, Retsu reappeared a moment later, but this time he was behind them, now standing a good five meters away from where the group was. Everyone quickly turned around once they had spotted him, and quickly went on the defensive. But Retsu didn't attack yet, indeed, he seemed more interested in his new form. He quirked his head to the side and threw a swift kick, followed by a few punches, and ending with a jump into the air before landing back down with fluid ease.

"Hhhmmm...I'm faster than I thought, it might take a while for me to adjust to this new form." Retsu said to himself before focusing back to our heroes "Riders, ponies, reptile."

"I'M A DRAGON!" Spike exclaimed.

"Would you all be so kind as to help me to test out this new body of mine?" It was more of a rhetorical question as Retsu didn't wait for a response. The blue and red gemstones on his chest began to glow, and the etched in lines began to glow with the same two colors. Into his right hand, which now resembled that of Demushu's forearm, a flash of red light went off and from it formed Demushu's signature sword. While Retsu's left forearm takes on the form of Nazca's forearm, with a flash of blue light ignited and now he was holding Nazca's sword. At that same time, the fiery wings of Nazca flared from Retsu's back. The newly transformed Kaijin took one step, and in no time, he had closed the distance between himself and the heroes.

Double and Gaim reacted quickly, with Double blocking the Nazca Sword with their Loyal Sabcalibers and Gaim blocking Demushu's sword with his Honesty Smasher. The action created a shock wave that forced the others back, thankfully Twilight and Eddward used their magic to kept their pony friends from being thrown off the ship, while the Riders were able to stand their ground under their own will.

"What in the world...is this!?" Shotaro said with a shocked voice.

"He's much faster than regular blue Nazca. As if he was Red Nazca!" Philip exclaimed in concerned.

"Not only that, he feels stronger than Demushu. But how is that possible?" Gaim shouted in puzzlement.

"They're right! He's even faster than when Rainbow was still a monster!" Taro said in a stunned voice, a pony bearing the speed element he could tell that Retsu was even faster compared to Rainbow who was previously Nazca, earning a burned hiss from the said rainbow mane pegasus.

"And from the feel of it, that force is a lot more intense than when cowgirl here clashes with orange guy there." Duncan commented before he realized who he's talking to "Um...no offense." He said to the apple farmer and the orange rider.

"None taken!" both Applejack and Gaim said.

Retsu mockingly laughed at them as he took a step forward and pushed them back. "It's a lot more simple than you all think." he pulled his weapons back, and with one swift, he slashed Double across the chest and on the back swing struck Gaim with the other sword. Both Riders were sent flying away as sparks erupted from their armor. Twilight and Eddward used her magic to catch the two Riders before they were completely blown away with Rarity and Eddy threw in their magic to support the Alicorns, slowing the two Riders down enough for them to stand up right again "Princess, remember when Chrysalis mentioned that we had something special for you?" he said, getting Twilight's attention.

"Just what sort of scheme does such a vile abomination have for the Princess of Friendship!?" Rolf demanded with an edged in his tone.

Retsu on the other hand seemed pleased, as if he felt complimented to how Rolf addressed him "I glad you ask pony. You see, what I have just injected into myself...was originally meant for you, Princess Twilight!" the mad scientist revealed.

"WHAT!?" everyone on the hull was shocked to the core.

The mad genius chuckled at their stunned expressions "You see, experimenting with Changeling DNA has opened up so many new possibilities of genetics and magical experimentation! Some of you have already seen Chrysalis' new form, but...I wanted to try something more...outrageous!" he said with a sadistic glee.

"What do you mean by 'outrageous'?" Prince Eddward asked.

"I have always wanted to combine different Kaijin abilities together, but I hit a roadblock in my studies. A Phantom's magic could not mix with an Inves powers, nor could a Greeed mix powers with a Zodiart or Dopant, it was so frustrating!" he said with rage before he looked back at them "But then Chrysalis and her Changelings come in! Their genetic makeup and magical energy allows them to change practically everything about themselves! They can change their gender, copy their appearances with other beings and even change to match with inanimate objects!" the mad scientist said with glee "When i extracted their DNA and use it as a base before combining Kaijin powers, I got my results!" he said in pure excitement.

"And I though Double D was the science geek." Eddy whispered to Duncan who nodded in agreement.

"I tested this further with those five!" Restu said as he points at the five mares that were once monsters "The Changeling cells allowed the power of five different types of Kaijin to meld with their DNA without any severe side effects!" he declared proudly at himself.

"YOU TURNED US INTO MONSTERS! YOU MADE US HURT OUR FRIENDS!" Fluttershy yells in absolute rage, surprising everyone around her, though none of them blame her for it.

The silver Kaijin only shrugs in respond "Well it does have some personality alterations, but once I saw that it was easy enough to correct for the next batch and it's much easier to control you all that way thanks to Chrysalis's mind controlling spell. I have always wanted to create the ultimate Kaijin." Retsu said with a enthusiastic manner as he points right at Twilight herself "And what stronger kaijin could I make by combining five different Kaijin types into the body of one of this world's most powerful beings and the wielder of the Element of Magic, Twilight Sparkle herself!? Could you imagined how powerful you would be!?" The monstrous being exclaimed.

Twilight was paled for a moment, realizing that if Eddy and his friends haven't intervened as they did and that the events in the lab were to gone out like Chrysalis and Retsu had initially planed. Then she would have become the very thing that was standing right before her right now.

"I see that you understand how things could have turned out. But due to the inference of that lizard-" Retsu began to explain.

"DRAGON!" Spike corrected.

"And then these interlopers interrupted." Retsu said, referring to the Colt-de-sac gang "My original plans have been halted. But no matter, since you're back to full health, I'll just take in all of you again, but this time we'll go for ten different Kaijins instead. There might be some cellular damage during the process, but I'm confident that it will-" The mad scientist was about to explain further until.

"OH JUST SHUT UP ALREADY!" Eddy who finally got fed up with the mad scientists' babbling yells as he unleashes a massive gust of wind at the monster. But Retsu hold his ground, then Wizard stepped in and fired several diamond aura shards from his spear at him. But the yellow gem on Retsu glowed and suddenly he splits into two just like the Gemini Zodiart and avoided the attack.

Fourze then aims his party bazooka and fires several sparkling energy cannonballs towards the two Retsu's, creating an explosion upon impact which kick a cloud of smoke and dust which obscured him from view. Double and Gaim charged back in with the half and half Rider aiming for Retsu #1 while the fruit themed Rider targets Retsu #2.

Retsu #2 summons Demushu's powers as he's glowing with red energy before creating the Overlord's signature sword and swings it right when Gaim strikes his Honesty Smasher axe. While Retsu #1 was dueling with Double, their attacks were quick as the ring of sword blades clashing rang out through the air.

"You really should remember, you're not only fighting an Inves, buuuuuuut…" The navy crystal shined and suddenly, octopus tentacles sprouted from Left Retsu's back and shot forward, wrapping around Gaim's arms and legs. "You're also fighting a Greeed as well!" Electricity coursed through the tentacles, hitting Gaim and making him cry out in pain from the electrocution.

Seeing Gaim in trouble, the Colt-de-sac stallions prepared to joined in, but Fourze halted them with his arm out "No! You guys look after Twilight and her friends! We'll hold him off!" he said.

"What!? But!" Duncan tried to argued.

"He's right! We can't let them capture Twilight and her friends again!" OOO's agreed with the space Rider as he spread his wings and flew up high, not before long he drops back down as he struck Retsu #2's octopus tentacles, releasing Gaim as he stutters from the electrifying shock.

OOO took this chance to attack, but this time used his horn and eyes utilized Fluttershy's Stare. The purple crystal on Retsu's chest glowed, causing his visor to change to the same color as it released a flash of light. The two stares in turned cancels each other out as the intensity of the attack could only be felt through the atmosphere.

Meanwhile, Double was still engaged with Retsu #1, but with a red gem glowing, Retsu was channeling Demushu's strength along with Nazca's speed, making Double have to be on the defensive as each blow knocked him back. The silver Kaijin and the cyan blue Rider clashed blades once again, the reverberating force causing Double to stagger. The mad scientist took this chance and closed in for another attack. At the last second, Fourze appeared and grabbed a hold of Double, the two of them disappeared as a balloon appeared where they once were just as Retsu #1 slashed at it and popped it.

As Retsu #1 searched for his opponent, he realized too late that in the small window of time between when Double was saved by Fourze, the sky was littered with dozens of cannonball sized crackling balls of energy. In a split second the crackling firework cannonballs all launched at the same time, which converged on him, creating a massive explosion. Fourze and Double waited for the smoke to clear, but their observation was cut short as the silver Kaijin burst from the smoke and smashed into the two with a clothesline attack with both his arms. Fourze and Double were dragged across the battlefield at great speeds until they were upon OOO and Gaim.

Retsu #1 stopped suddenly, sending Fourze and Double flying from the sudden stop in momentum. Fourze crashed into OOO while Double hit Gaim. The Honesty Rider managed to dig his heels into the hull of the ship to catch Double. OOO flared his wings at the last second, acting as a parachute to slow them down and stop their forward movement. All four Riders stopped at the same time, each of them physically worn out from Retsu's attack and their battle to free the true bearers of the Elements earlier.

Both halves of Retsu reemerged into one being, the Super Kaijin laughed manically as the five gemstones on began to glow. "All your wondrous powers amount to NOTHING!" he said as he builds up more power in the gemstones before all five of them released a burst of energy that streamed towards the five Riders, an aurora of colors that roared with fury as it drew closer and closer. Wizard stepped up before his allies and switched out one of his magic rings on his right hand as he placed his right palm on his Driver.

DEFEND! PLEASE!

Wizard stabbed the blade of his Di-Assail into the hull and immediately formed a dome around them made of pure white diamonds. The beam crashed against the barrier, washing over it like a stone in a raging river. Inside the dome, Wizard was visibly straining to keep the shield up, but fissures began to show with each passing second, cracks are connecting to other fissures that formed.

"I can't hold it much longer!" Wizard said in pure struggled.

Princess Celestia the co-ruler of Equestria had been defeated. The Alicorn of the Sun was barely standing, her legs shaken, her breath shortened and her once vibrant mane was now dull and limp. She was standing on the far other side of the ship and a few feet away from her was the Queen of the Changelings Chrysalis, now in her Kaijin form and appeared to be very pleased with herself.

"You really did put up a fight I will give you that Celestia. But it's a shame that it wasn't enough to save you." Chrysalis mocked.

"Oh it was enough alright..." Princess Celestia said in a raspy voice as a smirk formed on her muzzle "...Considering that all of this was nothing but a distraction." she revealed.

Chrysalis eyes widened as rage began to fuel within them "WHAT!?" she yelled.

"I have been keeping tabs on what's been happening on Eddward's side, I felt the magic from the Elements of Harmony resonate moments ago. By now the original bearers have been freed from your and Retsu's control!" Celestia gathered her strength and stood tall before the Changeling Queen "It's over Chrysalis!" she declared confidently.

At that moment, an aurora beam roared past both Celestia and Chrysalis. The beam struck against the hull, setting off an explosion that made both rulers turn away from the brightness. Smoke and dust were kicked up, obscuring whatever was inside the smoke cloud. A gust of wind blew through, pushing the cloud away and bringing into view that which was hidden. Much to Celestia's dismay and Chrysalis' delight, all five Kamen Riders were on the ground, each of their forms were in various states of armor damage. Damage that their Elemental forms could not bear as Wizard, Gaim, Double, OOO, and Fourze each had their new forms disengaged as they returned to civilian form.

The five Elements of Harmony floated before them, but only for a moment before changing back to their original state and falling onto the ground. Before Celestia could call out to the heroes, Chrysalis had crossed the distance between them in a matter of seconds and was now holding the Alicorn by her throat, lifting her up as she watched Celestia struggle against her iron grip.

"AHAHAHAHAHA! Behold your brave heroes and your ultimate weapon! Defeated! This is just perfect!" Chrysalis shouted in triumph.

The Changeling Queen tossed Celestia like a rag-doll far across the hull, her body landing before the six defeated Riders. Chrysalis flew towards them with her insectoid wings, but stopped short of the Elements, her horn glowed as she waved her claw tipped hand over the ancient items, making them float around her in an orbit as she admired Equestria's legendary artifacts.

A purple magical beam shot towards Chrysalis, but she merely used her staff to swat the attack away from her. To her displeasure, Twilight Sparkle and her apparently freed friends alongside the six stallions of the Arayan Kingdom were galloping towards them, in a matter of seconds the twelve ponies and one dragon were forming a protective semi-circle around Celestia and the Riders. Chrysalis sneered at them, but her attention was drawn elsewhere when she felt a presence approach them. Walking towards them was a silver insectoid type Kaijin, even in this form, Chrysalis could sense the familiar presence, but still had to be sure.

"Retsu?"

"Indeed Chrysalis, this is the fruit of my labor and your contribution to science! I now have the power to wield five different Kaijin types within one body. Your kind are truly remarkable." Retsu complimented.

Chrysalis chuckled as her body was engulfed in green flames, changing her back into her normal form. Silver flames engulfed Retsu, returning him to his human form, and looking quite pleased with himself.

"We now have five of the Elements of Harmony, while we may not have the Element of Magic, these five alone hold a power not to laugh at." Chrysalis said as she proudly have the Elements in her hands.

"Indeed, considering what I just witnessed." Retsu straightened his suit out and then snapped his fingers. All at once, different Kaijins ranging from Inves, Phantoms, Yummies, Dopants and Zodiarts descended around our heroes "My minions, kill them all. But make sure not to completely kill the Alicorns, half dead will do. I need them alive enough to run experiments." he ordered the monsters.

Chrysalis scoffed. "You and your experiments, it would be better to disposed of all of them." she proclaimed.

"Don't start, Chrysalis." Retsu warned as the two villains make their way into a hatch that led them back inside of the ship. Leaving the Riders and ponies at the mercy of their Kaijin minions.

"Well, this sucks! We finally break free of that mind control, only to be killed by a bunch of monsters five minutes later…!" Rainbow said in a deflated tone.

Shotaro managed to get on one knee. "We're not done yet!" he said determinedly.

Philip managed to stand up and offered his hand to his partner, helping him back to his feet. "That's right, so long as we breathe. We will continue to fight!" he agreed.

Rainbow Dash had a cocky grin after hearing the duo speak "What was I thinking? That's quitter talk, and I am no quitter! You guys are right, let's go!" she declared.

"Now you're talking some sense here." Taro commented as he stood by the rainbow mane Pegasus.

Kouta chuckled and tried to rise, but only to wobble a bit before Applejack and Duncan rushed to his side to keep him from falling back "Thank you, sorry for being a burden." he replied.

Applejack vehemently shook her head. "Fella, after all you did for us, yer definitely not a burden." she said.

"Yeah, you guys were awesome back there." Duncan agreed "Despite how weird your powers are." he whispered the last part quietly.

"We can't let hope die out, not here, not for this world or any world. We've come too far to let them win now!" Haruto declared as he stood back up on his feet.

"I must agree, my hopes and dreams, those of my friends and of my little sister. Everypony precious and dear to me, I won't let them fade away!" Rarity added.

Eddy grins in respond "You two are speaking my language!" he agreed.

"I normally can forgive a lot of things…but…I will NOT forgive them for making me hurt my friends." said the infuriated Fluttershy.

Eiji stood beside the yellow mare and smiled at her. "You're right Miss Fluttershy, we mustn't let them get away with their deeds!" the vagabond agreed.

"Aye, aye! The poor excuse of a queen and the delusional monstrosity must be served with the taste of justice!" Rolf declared.

Pinkie Pie looked at the teenager with the pompadour hair and the large yellow stallion with a grin "Ready to kick some tail?!" she asked.

Gentaro smiled back and beat his right fist against his chest before extending that fist to Pinkie Pie. "Always ready, I just caught my second wind!"

Ed smiles at the pink pony "Yeah! I'm with you Pinkie!" he said cheerfully.

Twilight, Eddward and Spike helped Celestia back on her hooves. The Princess of the Sun looked to the group and smiled warmly. "The Elements couldn't have chosen better candidates to come to our aid, wouldn't you two agree?" she asked her former pupil and the prince.

Twilight looked back to her friends, ponies and human, and smiled a broad smile as the despair of this situation began to melt away with her growing confidence.

Eddward nodded positively "I do agree, and everybody's right. We have to press on!" he declared.

Spike smacked his left fist into the palm of his right claw and snorted out emerald flames "I got your back Twilight, I still owe them payback for what they did to you!"

"Still…" Twilight eyed the Kaijin who were steadily getting closer. "A moment to catch our breath wouldn't hurt…"

Just then, the sound of thunder erupted behind the small army of Kaijin, suddenly a portal of swirling blue, purple, and green light emerges as it seemed to be expanding more and more with each passing second. When the thunder stops, another sound took over, the unmistakable sound of roaring motorbike engines.

All at once, four motorbikes leaped out of the portal and atop those vehicles, were the Secondary Kamen Riders. On the far right, wearing a knight like armor that resembles a banana (no seriously a banana!) while riding a rose decord motorcycle. This was the leader of the Beat Riders group Team Baron, Kamen Rider Baron.

Next to Baron was a space themed Rider much like Gentaro, but this Rider had a helmet with the top half blue with four comet-like tails coming from it, and a suit that appeared as if the vast space itself was stitched into it, along with a single blue shoulder pad on his right shoulder that resembled a planetary ring system. He is one of Gentaro's close friends, Kamen Rider Meteor.

On his left was a Rider in black, green, and silver armor, with a jade colored orb mounted in his right chest plate while riding a yellow and black motorcycled called the Ride Vendor, this was Kamen Rider Birth.

The last Rider was donned in gold and black armor suit, his left shoulderpad had a lion's face and mane, and his helmet was in the shape of a lion's mane with green compound eyes. Another magic user, one who wields ancient magic, Kamen Rider Beast. Compared to the other motorcycles, the one Beast rode looked like another Rider, it was red and silver, with a blue visor. Actually, it was another Rider! This was none other than Kamen Rider Accel in his Bike Form.

"Well it's about time!" Eddy exclaimed angrily.

"Accel!" Philip said with a smile and pure relief.

"Terui?!" Shotaro shouted in surprised.

"This is completely undignified!" Accel shouted in annoyance with Beast riding on his back.

"Well I'm sorry if I'm the only Rider here without a bike of my own! I mean seriously, how unfair is that?!" Beast replied.

"Guys! Focus on the task at hand!" Meteor scolded the two as he leaps of off his motorcycle which turned into star like particles before disappearing back into the portal. The space theme Rider landed on the hull of the ship, skidding to a halt as sparks erupts from his boots. Using his momentum, Meteor spun around as he neared the first Kaijin and delivered a spinning roundhouse kick to the creature's head, sending it flying across the hull and off the side.

Two other Kaijins moved in to engage, but Meteor was ready, blocking the first Kaijin's fist with his forearm. Meteor gave a loud "Hooo-Wah!" before slamming his fist into its chest, making sparks fly off from its body. The second tried to swipe at his legs but he jumped up at the last second to avoid a direct hit, while in the air Meteor pressed down one of the levers on his Meteor Galaxy device.

MARS! READY?

OKAY, MARS!

Kamen Rider Birth landed next, dismounting from his bike quickly and having it return to the portal as he pulled out his weapon, a grey metal gun with a auxiliary grip like pod that was mounted on the fore end of his firearm fuel with Cell Medals. He aims his gun at the incoming Kaijins as he fires it numerous times at them, hitting every single mark on them.

Meteor's right fist was surrounded by a red energy construct that resembled the planet Mars. The construct planet ignited into flames as Meteor descended and struck the Kaijin with his Mars Breaker, making the monster explode in a magnificent blaze.

Kamen Rider Baron revert his motorbike into it's Lockseed mode as he began slicing through one Kaijin after the other with his lance like spear, which fittingly resembles a peeled banana. One creature after the other tried to attack him, but each one was met with a quick sidestep and spear through their guts before either exploding or dissolving into nothing, dependent on Kaijin type.

"Is it just me or is that guy somehow reminds me of a banana." Duncan commented and the rest of the stallion gang could see it as well.

"Kazuraba!" Baron called out, getting Kouta's attention "You have some explaining to do as to why I was brought into this ridiculous situation!" Baron demanded while pointing his weapon threateningly at Kouta before turning back to fight the army of Kaijins.

Beast was driving Accel in his bike form around the hull, striking the Kaijin with the front wheel or balancing on the front wheel and smacking some unsuspecting Kaijin in the face with the rear tire. After about half a minute, Accel then got Beast off his back like a bucking bronco, having him landed on his rear.

"Hey! What gives Terui!?" Beast exclaimed.

"Get off my back and do your own fighting!" Accel scolded the other mage Rider.

"Well you didn't have to throw me off like that!" Beast huffed as he crossed his arms and legs.

Accel stopped and turned around to glared back at Beast who appeared to be nervous, thinking that he might have ticked of the policemen. Suddenly the Rider shifted back to his humanoid form and brandished his Engine Blade, which appeared to be a combination of a sword and a motorcycle engine and throws it right at a Kaijin right behind Beast as the monster growls in pain, before Accel rushed towards it and pulled his blade out of the monster and kicking it away.

"Stay on your guard, this isn't the time to be sitting around!" Accel told the maged Rider as he turned around to see several Kaijins charging right at him. He immediately slams the blade of his weapon on the hull of the ship as he squeezes the clutch on the left handlebar of his Accel Driver.

ACCEL! MAXIMUM DRIVE!

The belt announced as it emits a roaring motorcycle engine sound before he grips the right handlebar and keeps turning it multiple times, causing his entire suit to charged up in orange flames. He then charged at the Kaijins before he jumps up high and performed a spinning heel kick right at them, creating a red energy attack resembling red motorcycle skid marks on the monsters as sparks erupted from their damaged bodies before exploding in the process.

Birth then removes the auxiliary grip like pod from the fore end of his Birth Buster and reattached it on the muzzle of his firearm.

CELL BURST!

The weapon announced as it was charging with power as he aims it right at the incoming enemies before he pulls the trigger. Firing a massive energy bullet that resembled a large Medal coin right at the monsters, destroying the majority of them in an explosion.

Meteor then removed his Astroswitch from his belt and inserts it to the Meteor Galaxy device on his right wrist.

OKAY! LIMIT BREAK!

Meteor ran straight ahead, meeting the ongoing Kaijins halfway there. Once he was in range, Meteor began throwing rapid fire jabs with his right fist, each fist was coated with blue cosmic energy that made it look like comets were hitting down on the monstrous minions. The punches kept coming until the majority of the monsters exploded from his attack.

Beast took one of the magic rings which molded in the shaped of a falcon and pressed it into the right side of his Driver.

BUFFA, GO! BU-BU-BUBUBU-BUFFA!

Upon Beast's right shoulder, formed a mantle like pauldron which bore the head of a red bull with gold horns, and a red cape. Beast drew his Dice Saber and charged straight ahead for the Kaijin, the first blow was struck with a shoulder bash into a Shark Yummie, the super strength that was granted by this mantle made the Yummie fly into another group of Kaijins that were gunning for the Mane Six and Riders.

Baron then grab the knife attachment on his Sengoku Driver and pressed it down on his Lockseed twice.

BANANNA AU LAUT!

The fruit themed Rider swung his weapon around and thrust it into the hull of the ship. For a moment nothing have happened, but seconds later, the metal beneath the feet of the Kaijins began to rumble violently, until banana shaped projections erupted from the ground that skewer all of the Kaijins that were around Baron as they exploded in the process.

Suddenly Princess Luna, Princess Cadence, her husband Shining Armor and Eddy's brother emerged from the same portal which brought forth the five additional Riders have now landed on the hull of the ship and all four fired magical bolts from their horns to zapped a number of Kaijins around them.

"I don't get it, how are you all here?!" Kouta asked the Secondary Riders.

"The plan worked!" Phillip revealed in excitement.

"Plan? What plan?" Rarity asked curiously.

Prince Eddward cleared his throat, getting the mares and the 5 Rider's attention "Mister Philip and Discord have came up with the idea of bringing forth more Kamen Riders from the world that our current allies were summoned from." The Arayan Prince revealed.

"But without using the Elements of Harmony as conduits, the summoning spell should have taken a toll on all of our magic!" Luna explained.

"Fortunately Eddy's brother brought this can of spinach just in case, it really helps us to recovered from our fatigue and regaining our strength and magic back." Cadence said in gratitude.

"Good thing me and pipsqueak each brought one on us." Eddy's brother pointed out proudly "Otherwise one can alone won't be enough to fix up all of us." he stated.

"Hey I learned from the best big bro!" Eddy complimented his brother to received a noogie from said big brother.

"Everyone, hurry after the ones responsible!" Birth reminded the ponies and the main Riders.

"We'll provide support from up here, go and end this invasion!" Meteor added.

The Main Riders nodded as Philip take out a can with the remaining spinach inside and he took a small bite of it "Guys! Have some of these too." he handed them to Shotaro as he too take a small chunk of it before passing it around to Eiji, Gentaro, Haruto and Kouta. Once the five Riders are fully healed and energized, they ran towards the hatch that Chrysalis and Retsu retreated into. The five young mares quickly ran after them, each running beside the chosen substitute of their Elements.

"This is going to get dangerous, you guys may want to hang back." Shotaro suggested.

"Oh please, after what those plot holes put us through! It's time for some payback! No one makes me hurt my friends!" Rainbow Dash countered.

Phillip chuckled "Well, she's as hardheaded as you are, that's for sure!" he teased, earning a glare from his partner.

Haruto looked like he was about to say something, but Rarity cut him off by saying "Now dear, just because I'm a lady. Doesn't mean that I cannot 'kick butt' as it were!" she insisted.

"Never even crossed my mind." said the smug Haruto.

Eiji glanced to Fluttershy in worry "Are you sure you want to do this?" he asked concernedly.

Fluttershy nodded "I have to do this! I…I hurt my friend…those meanies made me hurt her! I can forgive a lot of things, but not that!" she stated with determination.

"Yeah! I bring smiles, not frowns! Friendship power!" Pinkie exclaimed.

"Friendship power!" Gentaro echoed along with her.

"Hope y'all can keep up with me, Sugarcube!" Applejack teased.

Kouta gave a confident smirk. "I'll try, Miss Applejack!"

"Call me, AJ!"

"Kazuraba!" Baron yelled, getting his semi-rival to stopped and turned around "Take this!" he said as he tossed a Lockseed to him.

Kouta looked at the new Lockseed, it had a shape unlike any he had seen before and it's bronze in color "Kaito, what kind of Lockseed is this?" the member of Team Gaim asked.

"It's a pick me up from Sagara." he explained to Kouta "He said you might find it meaningful. Much to my dismay." He said, feeling bitter to give away a valuable item to his so called rival.

Kouta simply sighed and rolled his eyes from Kaito's usual attitude before he followed alongside with Applejack.

Eddy's brother marched toward his younger sibling as he patted him on the back "Go kick their hind quarters Pipsqueak." he said proudly.

Eddy nodded determinedly as he looked back to his gang "You all heard him! Let's roll!" He said.

"YEAH!" All the stallion gang roared before they all joined alongside with the Kamen Riders and the Mane 5.

Twilight and Eddward looked to her friends and the Riders. The two then glanced back to Princess Celestia, Luna and Cadence and Shining Armor.

"Don't worry, we'll be safe and help the rest of the Riders to keep the monsters at bay. Go now, and end this plight upon our land." Celestia said confidently.

"She's right, just be careful out there." Shining Armor warned his sister concernedly.

Twilight nodded, unfurled her wings and raced off to join with the rest of the group. Prince Eddward nodded "You all take care now." He replied as he too flap his wings alongside with the Princess of Friendship.

The three Alicorn Princesses looked down at the young dragon who remained in place beside them "We're surprised that you didn't run of to join them Spike." Luna said.

"Nah, I think I helped them enough. Besides this is something that they need to do, especially since Eddy and his friends are with them now." Spike answered before he looked back at the incoming army of Kaijins and Changelings "Besides, I know that they will come back!" he determinedly said.

Cadence smirked teasingly "Well then the Great and Honorable Spike, I guess you can show how Brave and Glorious you can be." she said.

Spike grinned back as he put the collar back on and immediately his entire body flashed in a bright light as he turns himself into an Ursa Minor as he roared at the incoming minions.

"Whoa! Where did that thing come from!?" Beast screamed in surprised, sure it's not as terrifying as his Chimera Phantom, but it was still an unexpected sight.

"Don't worry, that's a little trick I gave to a little dragon." Eddy brother said with a smug as he slashes a Kaijin behind him with a sword.

Chrysalis and Retsu made their way down into the heart of the ship, a wide open platform made for hundreds of dozens of workers, at the center of the room was the giant power core that fueled the ship, a swirling ball of energy that was being contained within three oscillating rings. The two villains paused when they heard multiple explosions going off outside, but what concerns them was that now they were hearing a few of them from the inside, and they were getting closer.

"Impossible, they were surrounded and weakened. Why is there so much resistance?!" Chrysalis asked.

Retsu reached into his lab coat and pulled out a device, with a push of a button he was able to get a view of the outside and it was there he saw five more Riders, the three Princesses of Equestria, a different pink pony and the lizard now as an Ursa Minor, fighting off their forces outside. The Foundation X scientist flipped it around and showed Chrysalis what was happening topside.

"Obviously, they got more help somehow. Damn Riders, just when you think you have them on the ropes, something happens to turn the tide in their favor." Retsu said with irritation.

"Then that means Twilight and the rest are heading towards us." Chrysalis concluded before she noticed a very familiar pink Alicorn Princess on the screen "Wait...is that?" she was about to said.

Until an explosion rocked the room as the doorway to the reactor room was blown open, and in came the heroes of Equestria, Twilight, her friends along with Eddy, his gang and the five Kamen Riders, ready for one last battle with the villains who attacked this peaceful world. The six mares and six stallions glared at Chrysalis, while the Riders kept their eyes on Retsu, ready to defeat them once and for all.

"It's over, Chrysalis! No more running!" Twilight stated.

"Same with you Retsu! You've caused enough pain and suffering, it's time to end it!" Shotaro said.

Retsu put the device away and chuckled at the Riders and ponies "Please, you could barely keep up with me. Chrysalis thoroughly trounced your princess, and that was without my help. What hope do you eleven have against the two of us? Especially since we have five of your six Elements of Harmony?" he crossed his arms and continued, "Face it, you've lost. Chrysalis and I will take this world and Foundation X will gain new test subjects and Chrysalis will have a land to rule!" he claimed.

"Actually, I'd rather just rule." Just then, a beam of emerald light struck Retsu at his back and sent the scientist to the floor. The Riders and ponies all looked at Chrysalis in shock of what she just did.

For Retsu, he managed to get onto his hands and knees and glare daggers at the bug horse behind him "Chrysalis, what the hell are you doing?!" Retsu demanded.

"I have five of the Elements of Harmony, a whole hive of enhanced Changelings thanks to you, and I'm strong enough to take down Celestia herself without feasting on love first. Just think of how powerful I'll be once I start siphoning love energy from the ponies! No one will stand above me!" At that moment, emerald flames erupted around Chrysalis, transforming her into her Kaijin form "And that includes you, Retsu." she said while menacingly pointed her weapon at him.

The Foundation X scientist glowed as his body reverted back to his Kaijin form, now standing before the traitorous Changeling Queen. "Think about what you're sayin, Chrysalis. Without me, you'd be scurrying about this land, plotting and failing at trying to defeat these fools! Within less than a couple of days I granted you the power to fell your enemies! And now you're turning on me!?" he accused.

"I'm a Queen! I don't need you or Foundation X to rule these ponies. I thank you for giving me and my hive these powers, but now that we have it, I can create more just like them." Chrysalis said "And once we feast on love, we'll be far stronger than anything you or any world could muster as we spread out across Equestria and eventually, other worlds!"she declared triumphantly.

The Riders went wide eyed at this declaration. For the four, their homes and cities were free from threats after long and hard fought battles, but to have creatures like the Changelings coming in and destroying that peace was unthinkable. It was worst for Kouta, the threat of Helheim and the Inves were still looming over his city and his friends, if there was one thing they couldn't take, it was an invasion from another world and right now, Kouta wasn't sure which was worse.

For the ponies, all they could think about were their homes, their friends and families. The first Changeling invasion was bad enough, but now that they were empowered with the ability to change into powerful monsters from another world, monsters strong enough to overwhelm Celestia and Luna, and possibly Discord, no creature native here will be safe from them.

"You ungrateful wench!" Retsu shouted as he sped towards Chrysalis.

The Changelings Queen still kept the Elements in her telekinetic grasp, raised her right hand just as Retsu threw a punch at her, and caught it in her palm. The resulting shockwave shook the room and platform and made Chrysalis dig her feet into the metal "Do you know what the difference between us Retsu?" she said.

"What's that?!" he demanded.

"You have no real imagination. You develop a serum that could grant you the power of five Kaijin, but you don't know how to wield them properly. But thanks to your experiments. I have not only their DNA, but through that DNA I have evolved!" Chrysalis' body erupted with emerald flames, Retsu, the Riders, and ponies watched as Chrysalis underwent a transformation. The body of the Changeling Queen shifted until she was now in a new Kaijin form, one that Retsu wasn't aware of as his eyes widened and strangely, so was Eiji.

Her new form was scaly and blueish purple in color, she had a pteranodon head attached on each two of her shoulders with a pair of pteranodon wings on the sides, acting as capes. Along with purple arms and legs with reptile like hides resembling of a dinosaur's skin, plus a triceratop's head on her chest with two horns on it, her head resembles a T-Rex's skull with a red visor where here eyes should be.

Eiji shook his head back and forth "No…it can't be!" he said in horror.

"Mr. Eiji, what's wrong?" Fluttershy asked. "Do you know that thing?"

"That's…the Kyoryu Greeed, Maki Kiyoto!" Eiji answered in panicked.

Retsu didn't understand what he was seeing "This isn't possible, I never coded your DNA with this Kaijin?!" he said in shocked.

"No, you didn't. But you did provided the roadmap that allowed me to get to this form." Chrysalis squeezed her hand around Retsu's fist and made the Foundation X scientist flinched in pain. She then whipped Retsu to her left, throwing his body off to the side.

However, Retsu splits into two. The clone caught him and dug its heels into the floor, stopping his momentum. Retsu growled with anger as his red and blue gemstones glowed, summoning Demushu and Nazca's swords, while also drawing on their strength and speed. With a single step, both Retsus dashed across the platform to engage with Chrysalis. But Chrysalis' body erupted with emerald flames and her body shifted again and when she did, Retsu felt his body grow extremely heavy to the point that it was like moving through tar.

The new form of Chrysalis was white, black, grey and gold armor like skin along with a bit of bronze, half of her face resembles cities and skyscrapers with similar matching shoulder pads. Along with a red cape and she's holding a cane as she uses it to comand the two Retsu's to stop. Shotaro and Phillip recognized this new form, and they weren't happy about it.

"That's…" Shotaro began.

"Utopia Dopant!" Phillip finished.

Chrysalis flicked her cane down, forcing the Retsus to go flat onto the ground. With another flick, Chrysalis sent the two flying into the air. The Changeling Queen changed her form again and this time it was Gentaro who recognized this new form. It was black, gold, orange, and red, she had a yellow cross on her abdomen and she had a roman centurion armor look to it, along with a crossbow-like weapon attached to her left arm.

"Sagittarius!" Gentaro exclaimed in shocked.

Sagittarius Zodiart created a bowstring made of orange light, she then drew the bowstring and released several energy arrows that homed onto the two Retsus. Dozens of arrows struck the two Retsus, exploding in midair both Retsu's fell to the platform and forced to merge back into one. The Foundation X scientist's blue gem shined as he channeled the Greeed Mezool, and transformed his body into water to try and advance on Chrysalis.

The Queen scoffed as her body shifted for a fourth time, now she was something else. A green and gold, almost insect-like humanoid being, wearing a formal green robe and gold jewelry like accessories on her head, while wielding a gold halberd-ax in her right hand. Kouta knew this one, this is one of the Inves Overlords.

"Redyue!" Kouta gasped.

Redyue raised her weapon and struck the butt of the halberd against the platform, she then focused the soundwaves towards the water, raising their frequency to the point that it would cause intense pain. The soundwaves struck the water form of Retsu, making him stop his advance and change back into his solid form, on his knees and gripping his head with pain.

"Let's end this shall we?" Chrysalis changed for a fifth time. Now her body was white with a few grey streaks, with several blade like edges, only a mouth and nose with no visible eyes and a purple stone orb at the center of her torso .

Haruto knew this form well and was loathed to see it again, clenching his fists as he spoke its name "Carbuncle…"

The Phantom reached out both hands, purple magical energy covered them and then that energy shot towards Retsu. The silver Kaijin locked up as he felt his body grow weaker, the crystals on his chest were going dimmer and dimmer, until Retsu was forced to change back into his human form just as Chrysalis stopped her attack.

Retsu panted, both exhausted and in pain from the battle. "You…how dare you backstab me you insignificant bug!" he yelled

Chrysalis returned to her previous Changeling Kaijin form, and slowly strutted towards Retsu "Oh don't be mad, Retsu, you should be proud of yourself. You created a powerful Kaijin, one that will eventually topple all others in every world. I'd say you've completed your greatest work, and now you can die knowing you accomplished something great." she stated cheerfully.

Retsu reached into his lab coat and took out a remote control like device "Did you honestly think that I wouldn't have a contingency plan?! Did you really think I trusted a creature like you?!" he said sinisterly.

Chrysalis took a step back "What are you saying?" she said confusedly.

Retsu stood up and began to chuckle darkly. "I figured you might try and betray me. I never believed for a second that you didn't have an ulterior motive! So, I implanted a device in your body when I was working on you, one that will kill you the moment I activate it!" he revealed.

Chrysalis had a panicked look on her face as she began to pat down her body, as if trying to find the device.

"DON'T!" Eddward shouted.

"STOP!" Twilight yelled.

"Goodbye" Retsu said as he pressed the button on the device.

"AAAAGGGGHHHHH!" Chrysalis screamed in agony as she clutched at where her heart would be, then she fell to her knees and took one last breath before she plopped onto the floor, completely still as the Elements fell a few feet away from her grasp.

The whole room was silent as everyone stared on in shocked "Okay, I saw a lot of backstabbing before. But this is just messed up." Duncan commented which the other stallions nodded in agreement.

"Hahahahaahahahaahahahaha! HOW DO YOU LIKE THAT YOU STUPID BUG!" Retsu shouted as he kicked Chrysalis' body on the side. "THOUGHT YOU WERE SMARTER THAN ME?! I GAVE YOU YOUR POWER! I GAVE YOU NEW LIFE, AND I CAN TAKE IT AWAY!" he said with a psychotic mad smile.

Fluttershy looked away and placed her head on Eddward's neck, she never thought a creature could be so cruel as to take joy in ending someone's life as the Prince too looked on distastefully. Rainbow Dash and Applejack had no words to express what they just saw, Pinkie was just as silent as Ed wrapped his hoof around her in shocked. Rarity found the display more than vulgar, more than cruel.

Duncan, Taro, Rolf and Eddy were beyond disgusted at the act, sure they seen messed up things before, but this takes the cake. The Riders unfortunately had seen such things before, but that didn't make it easy for them to witness.

Retsu walked towards the Riders and ponies, stopping about halfway "OH DON'T GET SO WEEPY OVER HER! You can admit how you're all glad that she's dead now!" he rhetorically said.

"Actually Retsu, I'm not."

Retsu felt his blood run cold as he slowly turned around, and much to his and the heroes' surprise. Chrysalis stood up, alive and well. "WHA! BUT H-H-HOW?!"

"I know my own body, Retsu. Changelings have an innate knowledge of all their body parts, we have to if we want to mimic whoever and whatever we want. So when I felt somethings off inside my body, I immediately removed it." Chrysalis explained.

"H-How long–?!"

"How long have I known? Almost an hour or two after you were finished enhancing me. It was then that I realized you had planned to kill me at some point, and with that knowledge, I decided to turn the tables on you before that happened. So I ripped it out of my body, painful, but thanks to what you did to me, I was able to heal very quickly." Chrysalis used her telekinetic magic to grab Retsu and bring him towards her. Along with that, she extended her weapon and at that moment, Retsu was impaled by the blade of it as Chrysalis held him in place. "But I'll be honest, I had planned on double crossing you from the beginning, that device you put just cemented my resolve to do so. Now, begone!"

Chrysalis whipped her weapon towards the reactor and flung Retsu in it, releasing him from her telekinetic hold and she let gravity do the rest. As he flew, Retsu could only yell, "CHRYSALIIIIIIIIIIIIIIIISSSSSSSSSSSSS…!" Before his voice went silent, no doubt continuing to fall. If there was a thud, it was drowned out by the whirring of the reactor.

Author's note: Now that's definitely a shocking betrayal on the villain's part, thought I bet that some of us could see it coming. Anyways, we're at the end game of this story. So expect the final battle to be explosive, hype and beyond your wildest imaginations.
