We do not own Koihime Musou or Kamen Rider Gaim. They belong to their respective creators. We just thought this idea would be fun and decided to give it a try. If you like it, then that's great. If you don't, then we tried. Anyway, come along and let's see what you think.

KRC: Before reading this fic, I recommended that you read the Kamen Rider Days Saga, the Kamen Rider Showa Saga and also the Armored War Gods Saga. It's a lot of prerequisite reading, but if you want to be able to understand who the characters are, then you'll need to read about them. It's a story that requires significant background knowledge. Also, this story takes place between Season 4 and Season 5 of the Armored War Gods Saga.

Legacy Part V: Clash of the Titans

Once they had defeated Kirikaze, Gaim and Ifrit returned to their default forms.

However, the battle was not quite over yet.

As the smoke cleared and the last of the embers died, Shiro Juuyon was revealed standing where Kirikaze had met his end.

"Shiro!?" Showa - who had changed back from his Legacy Form - gasped as he saw his evil doppelganger. Shiro Juuyon was the embodiment of everything Shinichi feared and hated the most. In fact, Shiro Juuyon was originally Shinichi's clone. Upon his creation, he had all of Shinichi's memories but he was an amoral monster.

Alan and the NEO-NUMBERS were just as shocked to see Shiro Juuyon standing before them. Like Shinichi, they too had a personal history with the evil bio-android and none of it was good.

He had been engineered to be a psychopath and had taken advantage of his resemblance to Shinichi to assassinate members of his team while Gebok held him captive. Fortunately, Shinichi had been rescued by Dr. Magi and Hitomi, allowing him to destroy his doppelganger and turn back time to revive his team.

Shiro Juuyon resurfaced years later as his Spark Core had been recovered and implanted into a new bio-android body. While Shiro still shared a resemblance to Shinichi, he instead had silver-white hair and red eyes like a twisted albino. He also found a new motivation: to kill Shinichi and become all-powerful.

Shiro hated Shinichi as much as Shinichi hated Dr. Gebok, their creator. The two clashed numerous times, with Shiro formulating a plan to become more powerful each time. Shiro had also used the resources Gebok had left behind to create an army of DALEKS and Cybermen, killed members of a clan tasked with preventing the Orochi from returning, then fused himself with the Orochi to take its power. Unfortunately for him, his hubris turned out to be his downfall and he ended up absorbed by the Orochi instead. However, his head had been saved and he ended up becoming a Supreme DALEK before being destroyed yet again.

It looked like LEVIATHAN had brought him back again and given him DALEK eyes as a replacement for his original ones. They may look like goggles, but the eyeballs had been implanted into the sockets, giving him a very unnerving appearance as they glowed with a cold blue soulless light. As a result of bonding with Kirikaze, he had demonic shark-like teeth.

"Damn you, Kamen Riders! You think this is over!? No, not when I have something to say about it!" Shiro ranted like a deranged madman. Now desperate to win at any cost, he took out a wicked dagger with a demonic skull on the crossguard.

Showa instantly recognized what it was.

"The Blade of Legion!" Showa shouted.

What Shiro held in his hand was the Blade of Legion, a dagger that had been forged with the essence of 666 powerful Horrors on the night when the veil between realms was at its thinnest. It gave its wielder unimaginable dark power by turning them into a vessel for the legion of Horrors.

There was a facility in ARMOR known simply as Storeroom-X which was used to house the most dangerous objects and artifacts in the entire Multiverse. It contained things that could destroy worlds, cause immeasurable disaster and generally screw with reality. So, it only made sense for the Blade of Legion to be locked away in Storeroom-X to keep it out of the wrong hands.

Kirikaze had broken into Storeroom-X and stolen the Blade of Legion, which was why Shinichi had been tasked with hunting him down. Now Shiro had the Blade of Legion and he was going to use it on himself.

"This is it! The big one! SEE YOU ALL ROT IN HELL, MOTHERFUCKERS!" Shiro held the Blade of Legion aloft to plunge it into his chest when he suddenly froze.

It was not just him. In fact, everybody froze except for Showa who calmly approached Shiro.

"Not so fast," Showa said. His ability to freeze time was definitely useful at times like this. It definitely saved lives more times than he could count. "And that doesn't belong to you." Showa went to snatch the Blade of Legion from Shiro when his DALEK eyes suddenly flashed.

"EXTERMINATE!" Shiro screamed as he threw his hand into Showa's chest and sent him flying with a burst of lethal energy. The Rider screamed in shock as he was sent sailing as his time freeze was canceled out.

"Huh?" Gaim blinked.

"What the Hell?" Ifrit wondered as he looked at Showa who was lying on the ground.

"Too bad for you, when they rebuilt me, they managed to install a tachyon device in me. That means your time powers won't work on me," Shiro gloated as the DALEK ray gun in his hand retracted into his palm. "And now for the final act!" He plunged the Blade of Legion deep inside of his chest. The instant he did, he let out a bloodcurdling scream as all 666 Horror souls contained within the dagger entered his body and took residence in their new vessel, horrifically warping him. Black smoke engulfed Shiro as crimson lightning crackled in the cloud. The black cloud began to grow and expand, becoming bigger and bigger with every passing second.

Gaim was reminded of the numerous battles in every Super Sentai series he had seen. Whenever a monster was destroyed, or close to being destroyed, they would somehow revive and become gigantic, which would then warrant the use of a giant mecha to finish them off for good.

Gridon and Kurokage-Shin were familiar with this scenario as they had played JRPG's before. The final boss always had another form after you defeated them in their first form.

The Shoku Warriors, Riders and Armored War Gods all gaped as Shiro emerged from the cloud in a new gigantic Horror form. It appeared Rider-like, resembling Shiro's original WHITE 14 form. However, this time it was organic as the white bodysuit looked like it was made of leather and the armor appeared to be made from silver-painted bones with a ribcage-like chestplate and skull-shaped spaulders. He had '14' etched into his right spaulder and XIV carved into his left spaulder. His head sported a V-shaped antenna with Cyberman handlebars and DALEK eyes with red lenses. Instead of a faceplate, he had mandibles that were filled with razor-sharp teeth. Mounted on Shiro's left arm was a shield and he carried an equally massive sword in his right hand.

Giga-14 looked down at the assembled warriors and raised his sword.

"EVERYONE, MOVE!" Gaim shouted for everyone to retreat. Giga-14 swung his sword to swipe it through them when a green dome formed around the group, shielding them.

It was Alan and he was using his ring to erect the barrier. Seeing as his sword would not be able to break the barrier, Giga-14 fired a powerful death ray from both his eyes.

"DELETE! EXTERMINATE! DESTROY! DELETE! EXTERMINATE! DESTROY!"

"You guys better have something that can take this thing down!" Alan shouted, his forehead beading with sweat, as he struggled to hold the barrier.

"Kishamoth, Tyrain, Cyrain, get over here!" Ifrit commanded. Seconds later, a loud trumpet and roars filled the air as the DynoLiner Mammoth, Tyrano and Tricera train cars roared into the scene, riding on their individual train tracks. "Make it rain, boys!"

The Tyrano roared and blasted fire at Giga-14 while the Tricera fired lasers from its horns. This was enough to send the giant Horror backpedaling away from the barrier as it tried to swat the trains away.

"That tickles!" laughed Giga-14.

The Mammoth used brute force as it bashed itself against Giga-14, knocking him back further. However, the three trains would not be enough to take this gigantic Horror down.

Luckily, Showa had something that could tip the scales and called forth the power within him. He threw his head back and shouted loudly:

"ARISE, DRAGON OF DRAGONS! DREIGON!"

Alan dropped the barrier the moment he heard that. Something big was coming and his brother needed space to do it.

With a roar, Showa's body glowed with a bright violet light which turned to gold as his glowing body began to grow to gigantic proportions and he changed into a more monstrous form. The light soon became so bright that those around him had to cover their eyes to protect them from the glare and to prevent them from being blind as a bat.

Showa's growing body shifted into an inhuman shape as his hands and feet became armored talons while large armored wings sprouted from his back. As he dropped on all fours, a long armored tail sprouted from his rear as his neck extended in length while his head assumed a more draconic shape.

Once the light died down, everyone uncovered their eyes and gasped. Much to the shock of everyone save for those who had witnessed this before, Showa had transformed into a gigantic dragon clad in knight-like armor. The armor was made of an alloy that mixed both Soul Metal and Dragon Metal. His head was covered in a black and white helmet with a set of forward-facing gold horns and etched with the number XIII on the left side and the number 13 on the right side.

Armor plating also protected his long serpentine neck with a spike hutting upward from each plate. His wings were made of Soul-Dragon Alloy with sharp razor-edged fans instead of the normally thin membrane. His forelegs had pauldrons and gauntlets with long, gold, sickle-like blades mounted on them, just like his hind legs. His chestplate bore the crest of Eclipse on it with a red gem in the center of it as well. His tail was also covered in the same segmented armor plates as his neck and the tip ended in a curved golden blade which was the Sword of Ascalon itself. On either side of the blade was a tachyon energy cannon.

This was Showa Ascalon Form DxD Mode.

"Dude just turned into a dragon!" Kurokage-Shin yelled.

"I know!" Gridon concurred.

"Dude just turned into a dragon!"

"I know!"

"DUDE JUST TURNED INTO A DRAGON!"

"I KNOW! WE GET IT!"

With a roar, Showa Ascalon DxD stretched his wings and took off to engage Giga-14. The two giants crashed into each other and Showa Ascalon DxD viciously attacked with his claws, pushing Giga-14 away from everyone.

Everyone - except the NEO-NUMBERS and Alan - was stunned by the shocking transformation and watched completely speechless as the armored dragon fought the giant Kaijin Rider. It took a moment for them to recover from their shock.

"Did an Armored War God just turn into a dragon?" Bacho asked.

"Yes," Ryofu confirmed. These guys were so full of surprises.

"So cool!" Chouhi yelled excitedly. "Go get him, dragon-niichan!"

Giga-14 recovered from the onslaught and went to strike the train cars with his sword, but Showa Ascalon DxD caught the sword between his jaws. Giga-14 raised his shield to protect himself from the Tyranno's flamethrower and the Tricera's laser horns.

Seeing the dragon in action, Ifrit decided to join the final battle too. He leaped into the Mammoth's cockpit where his Dyno-Breaker was already docked in the control unit and mounted it.

"Alright, guys! Let's take him out once and for all!" Ifrit exclaimed.

"Ryuji, I don't think we can defeat him the way we are now," Kishamoth stated.

"Then what do you suggest?" Ifrit asked. "I'm all ears."

"For something this big, we will need to form the Dyno King," Tyrain answered. "But..."

"But what?" Ifrit asked. He hated it when there's a 'but' included.

"It requires almost all our energy. Afterward, we will go dormant. Then our memories of you and your memories of us will be erased," Cyrain explained.

"WHAT THE FUCK!?" Ifrit screamed when he heard that. "ARE YOU FUCKING SERIOUS RIGHT NOW?!"

"Ryuji, language!" Loki admonished.

"No! Fuck no! No fucking way! I don't want to forget you guys! We just started getting to know each other!" Ifrit argued furiously, ignoring Loki's admonishment.

"It'll be fine. We'll see each other again and make new memories," Kishamoth promised.

"We possess a strong bond," Cyrain added logically.

"So let's meet and be friends again!" Tyrain finished cheerfully.

Ifrit gripped the handlebars tightly. Because of what Ryuki's father, Kyosuke, had done to his family, Ryuji also had abandonment issues.

"Is there really no other way we can beat this thing?" Ifrit asked. "Banabara did just turn into a dragon."

"As strong as he is now, against this Horror, I doubt it will be enough," Cyrain observed.

"Fuck, I hate it when you make sense," Ifrit muttered. "You guys sure about this?" The three DynoLiner Imagin gave Ryuji their affirmative. "OK, but we'll see each other again after this, OK? You better promise me and no bullshitting, alright?" The DynoLiner Imagin confirmed it. "Alright, here we go! Kishamoth, Tyrain, Cyrain, let's combine!"

The Mammoth broke apart before coming back together to form the torso as the head became the chest while the wheels and rods formed the arms. Meanwhile, the Tricera and Tyranno both bent 90 degrees at the neck, forming the legs for the giant mecha form. They connected to the thighs which hung under the Mammoth torso and a human-like head with a dinosaur helm sprang out from the top. The eyes of the mecha flowed as the horns swung over to attach themselves to both sides of the head, completing the transformation.

"Combination Complete: DYNO KING!" Ifrit shouted as the Mammoth's smokestack trunk released smoke.

He shed a tear under his helmet, knowing what this had cost him.

"Kyoretsu-oh!" Gaim shouted excitedly at witnessing a legendary Super Sentai mecha combination sequence live and in-person. "It's Kyoretsu-oh! The trains made Kyoretsu-oh! I knew it!" He noticed how everyone was looking at him and he calmed down, embarrassed by his nerdgasm.

"I know how you feel," Gridon said sympathetically as he occasionally had nerdgasms too.

The Dyno King marched toward Giga-14 and punched him right in the face. He recoiled from the blow and attempted to slash the Dyno King with his sword, but Showa Ascalon DxD slashed it across the chest with his tail blade, sending him staggering back.

"Guess they've got this," Baron observed.

Dyno King fired his Cryo Cannon as Showa Ascalon DxD blasted atomic dragon fire at Giga-14. As he was being bombarded, Giga-14 began to glow and let out a roar as he seemed to grow in mass. He charged forward and bashed the Dyno King with his shield, knocking it down and then swiped at Showa Ascalon DxD with his sword. The knight dragon backed away from the sword but then an additional pair of arms grew out of the back of Giga-14 and then stretched to capture the armored dragon. He then threw the dragon on top of the mecha.

Giga-14 raised his sword to the sky, conjuring a magical circle before dark lightning struck both the dragon and mecha. Inside Dyno King, Ifrit screamed as his mecha took damage while Showa Ascalon DxD let out a roar of pain.

Giga-14 went through his final horrifying metamorphosis. He seemed to be growing larger while an extra set of four arms grew out of the primary pair. Additionally, a tail began to emerge from his rear, tipped by a trident head and a huge pair of wings grew from the arms on his back, granting him an impressive wingspan. His helmet also became adorned with a pair of buffalo horns with a crown made of fire.

"OUR NAME IS LEGION! FOR WE ARE MANY!" the colossal Legion XIV bellowed.

Kurokage-Shin and Gridon hugged each other tightly in terror.

"And now it's in its FINAL FORM!" the two screamed together as they witnessed Legion XIV's horrific metamorphosis. This was no mere demon, but a mega archdemon!

"And it's referencing from the Bible too," Baron remarked.

They all watched as Legion XIV savagely attacked Dyno King and Showa Ascalon DxD, brutally overpowering them with their six arms.

"They're in trouble!" Gaim shouted and that was when something flashed and suddenly appeared in his left hand. Looking at it, he found that he was holding the Ultra Orange Lockseed. There was also another glow coming from his Kachidoki Lockseed. Both Lockseeds were glowing as if telling him something.

He understood.

Legion XIV grabbed hold of Showa Ascalon DxD's tail and used him as a club to savagely bash Dyno King. They seemed to be enjoying themselves. But all of a sudden, they were blasted from behind. They dropped Showa Ascalon DxD and turned around to see what it was.

"Who dares!?" Legion XIV snarled.

[KACHIDOKI ARMS! IZA SHUTSUJIN! EI, EI, OH! ULTRA ORANGE ARMS! DAI-HANAMICHI ON STAGE!]

There stood Gaim, as gigantic as an Ultraman. The Kachidoki Lockseed was in the main Drive Bay of his SengokuDriver while the Ultra Orange Lockseed was docked in the Genesis Core. He was holding the DJ Gun in his hands, the muzzle smoking after firing at Legion XIV right in the back.

"Nagata-sama!?" Kanu cried in shock.

"Wait, when did he do that!?" Bacho wondered. None of them had noticed Nagata sneak away to assume his gigantic form as they had been too engrossed in the Mega Monster Melee taking place before them.

Ultra Gaim combined his Musou Saber and DJ Gun to form the DJ Taiken which he held in his right hand and then showed that he also wielded the Daidaimaru with his left hand. Eyes narrowed in determination, the giant Blue King charged at Legion XIV. They swung their sword in response but Ultra Gaim blocked the blade with his Daidaimaru before slashing Legion XIV with his DJ Taiken.

Meanwhile, Showa Ascalon DxD and the Dyno King managed to recover and rejoined the battle. Legion XIV had been a match for two opponents, but could they handle three?

Well, we're about to find out.

Legion XIV summoned up more weapons to fill their empty hands. Along with the sword and shield, they now wielded a battle axe, a spiked mace, a long spear, and a hammer. Legion XIV smashed their hammer into Ultra Gaim, knocking him back. They then swiped at Dyno King with the axe but Dyno King ducked before delivering an uppercut into Legion XIV's jaws.

Showa Ascalon DxD gathered tachyon energy in its jaws and fired a blast that slammed into Legion XIV, knocking them back. At the same time, Ultra Gaim delivered a series of devastating blows with his DJ Taiken. Legion XIV raised their shield to absorb the attacks before they slashed Ultra Gaim in the chest with the sword. They then struck him with the axe before bashing him with the mace and finally jabbing him with the spear. Legion XIV then fired their optical energy blast, knocking Ultra Gaim down with an explosion.

Showa Ascalon DxD roared and slammed into Legion XIV, sending them tumbling. The dragon then fired diamond shards from his wings, keeping the Horror pinned down.

"LET'S FINISH THIS!" Ultra Gaim bellowed as he locked the Kachidoki Lockseed into his DJ Taiken.

"Fine by me!" Ifrit agreed.

Showa Ascalon DxD concurred with a roar.

[LOCK ON! 1, 10, 100, 1,000, 10,000, 100,000,000, 1,000,000,000,000, MURYODAISU! KACHIDOKI CHARGE!]

Inside the Dyno King, Ifrit held the Liner Cross-Rod and inserted his Dyno Pass.

[FULL POWER CHARGE!]

Showa Ascalon DxD hovered between the two giants and spread his wings while charging up another tachyon charged blast.

"FINISHING MOVE: GREAT TRIPLE RIDER ULTIMATE FINISH!" Ultra Gaim roared.

They delivered their attacks which merged into a single burst of energy. Legion XIV released a haunting howl as they were consumed by the blast.

"He's done for," Ifrit concluded.

"Wait a minute," Showa Ascalon DxD countered as his eyes narrowed. "I don't think it is."

The smoke cloud was so thick that nothing beyond it was visible. When the smoke gradually dissipated, slowly but surely Legion XIV's massive body was revealed. They were wounded but still standing. Not only that, but all the injuries they had received earlier were healing at an alarming rate. However, what truly shocked them was the large growth emerging from Legion XIV's groin. It extended forward like a ridiculously large erect penis.

"Oh, come on!" Musician yelled in disgust. "Do you really have to be a sick perv like Shinichi!?"

"I heard that!" Showa Ascalon DxD irritably exclaimed.

Then the growth split apart eight ways, blooming like some kind of fleshy flower. Now it looked like Legion XIV had eight penises. While the Shoku Warriors had seen some pretty bizarre things, this was unlike anything they had ever seen before.

"KYAAA!" Ryukendo screamed as she covered her visor with her free hand. "HENTAI!"

"Oh that's disgusting," Gekiryuken spoke.

"Oh Kami..." Draco choked as he struggled to resist the urge to vomit in his helmet.

Disturbed, Kanu quickly covered Chouhi's eyes to spare her from the sight of the eight demonic dicks.

Bacho tried not to gag at what she was seeing but it was challenging as it was just so horrendous.

Chou'un was just plain horrified as she screamed and covered her eyes.

Ryofu was oddly silent. Unknown to her comrades, she was imagining Nagata possessing similarly large and numerous penises. That way he would be able to please all of them at once.

Yes, she had a weird imagination.

But then it got a whole lot worse as a dragon's head emerged from each of the long penis-like growths. Now they were draconic demon dicks. To support their added weight in front, Legion XIV's rear extended and grew hind legs, giving them a more centaur-like appearance.

"He's the Yamata no Orochinchin!" Armadillo proclaimed.

"What the Hell!?" Ifrit demanded. "Even after all that, it's not dead yet!? And now he has eight dragon dicks!?"

"The Horror has eaten up so many people that it has drawn on their souls to heal itself," Showa Ascalon DxD informed Ifrit, recalling the Orochi. "And then there's the Blade of Legion. He can't die unless we vanquish all those 666 Horrors inside of him."

"Oh, now you tell me!"

"STOP ARGUING! WE JUST NEED TO KEEP FIGHTING UNTIL IT GOES DOWN!" Gaim bellowed.

The eight dragon heads fired different elemental blasts: fire, water, wind, ice, lightning, darkness, stone, and metal shards.

The blasts hit, causing explosions to erupt around the heroes. Ice burst out of the ground as it rained, a nearby forest burst into flames as a powerful typhoon roared, there was an earthquake and a lightning storm, and finally, metal shards fell, destroying homes. Fortunately, the occupants managed to flee. Alan also used his ring to summon a barrier to shield them all from the elements.

Ultra Gaim charged forward and swung both his swords but Legion XIV knocked him back with their combined elemental blast. The titanic Armored War God went skidding backward but was caught by Dyno King.

"We do this together!" Ifrit yelled as he sent the Dyno King charging. He fired the Cryo Cannon but Legion XIV used their wings to shield themselves before swinging their tail at the mecha. Dyno King caught the appendage but Legion XIV lifted the Dyno King and smashed it to the ground. Showa Ascalon DxD roared and fired at Legion XIV who fired back with dark energy beams from their eyes. The beams collided and the explosion sent Showa Ascalon DxD crashing to the ground, causing a tremor upon impact.

"They're in trouble," Alan observed with the rest of the spectators. Legion XIV had become too powerful now and was growing bigger and stronger with every passing second. They needed a miracle. Luckily for them, Alan was wearing one. "Bazel, think it's time for us to intervene?"

"I've been waiting for you to ask me that! Now, let's do what we do best!" Bazel yelled excitedly from the bracelet.

Alan smiled and watched the three heroic titans face the monumental evil again. He rubbed his hands together and sent a telepathic message to the trio.

"Shinichi, Nagata, Ryuji, I'm about to do something that might feel weird."

"Weird? Why? What are you doing?" Ifrit asked suspiciously as he was trying to beat the six-armed monster in a fistfight. Normally, he would be angry at any invasion into his mind, but it sounded like this Alan kid had an idea so he was willing to listen.

"WILL IT HURT?" Gaim asked as he was knocked back by a tail whip. He rolled away as the dragon heads snapped at him.

"It will allow you to beat that thing but you'll have to do it as one," Alan informed them. "Just trust me, OK?"

Ifrit and Gaim were confused but Showa Ascalon DxD immediately knew what was going to happen.

"Yeah!" Showa Ascalon DxD sent back. "Do it, Alan!"

"You hear that, Bazel? Let's do it!" Alan aimed the Bracelet of Bazel at Dyno King, Showa Ascalon DxD and Gaim. "IFRIT! GAIM! SHOWA! KAMEN RIDERS, XROS FUSION!"

"Fuck," Legion XIV cursed quietly when they heard those dreaded words.

A beam fired from Alan's bracelet and split apart into three which hit the three gigantic heroes. Gaim, Dyno King, and Showa Ascalon DxD levitated, much to their surprise.

Gaim was stripped of his armor, leaving him in his Ride Wear suit as Showa Ascalon DxD and Dyno King's bodies broke apart. The Tyrano and Tricera trains connected to Gaim's legs, becoming powerful boots. His upper body then became covered in the armor pieces made up of Showa Ascalon DxD's body. The head became the chestpiece, the claws became gauntlets, and the wings fit onto his back. Also, Dyno King's arms became shoulder pads with tachyon cannons mounted on them. The Mammoth train head became a shield while Showa Ascalon DxD's tail became a lance. Finally, Gaim's head became covered by a new helmet with Ifrit's visor covering his eyes and draconic horns on the sides.

"TRINITY FUSION! GREAT DRAGON KING GAIM! COMPLETE!" the fused gigantic warrior declared as he posed heroically.

Everyone gaped at the fused titan then back at Alan, then back at Great Dragon King Gaim.

"Did you...do that...?" Kanu asked, wondering what kind of god Alan was to be able to do that.

"Yes," Alan confirmed. "But now the rest is up to them. Go get him, guys."

Meanwhile, inside of Great Dragon King Gaim, Showa, Ifrit, and Gaim were standing inside what appeared to be a cockpit. The walls were silver and clean while the three Riders stood on individual standing platforms which were color-coded to a specific Rider. Gaim's blue platform was in the middle with Showa's green platform on his right and Ifrit's red platform on his left. Behind each of them was a banner with their personal emblems.

"Where are we?" Gaim wondered while looking around their new surroundings.

"Looks like Alan fused us together and this is what it's like inside," Showa said as he studied their control cockpit. "Neat."

"And how is this supposed to work?" Ifrit asked.

"Guess we work together to control this thing," Showa answered.

"He's coming!" Gaim alerted them as he pointed to the large screen that allowed them to see through Great Dragon King Gaim's eyes and it showed Legion XIV coming at them. The platform he stood on lit up as he raised his arms. Instantly, Great Dragon King Gaim copied his movements and blocked the impact with the Mammoth Shield. The blow sent the combined titan staggering back, but Great Dragon King Gaim still stood its ground. "Huh? Did I do that?"

"Looks like it, instead of forcing us to be in sync, we take turns taking control," Showa said.

"Then it's my turn!" Ifrit's platform glowed red as he took the reins. "Hyah!"

Great Dragon King Gaim blocked the next blow with his shield and charged forward. He thrust with the Dragon Lance, striking Legion XIV in the chest. His weapon pierced through their armor and the demonic giant howled in pain. They fired their beam blast at Great Dragon King Gaim who blocked the blast with the Mammoth Shield and then retaliated with a cryo blast from the Cryo Cannon. Legion XIV recoiled before they got a swift kick to the gonads.

"That's how you do it!" Ifrit smirked while wiping his thumb across where his nose would be.

"My turn then!" Showa announced as his own platform lit up, giving him control of their gigantic gestalt body.

Great Dragon King Gaim grabbed Legion XIV and flew up. The monster tried to break free, but Great Dragon King Gaim held them tightly. The combined titan then went into a nosedive and spiraled before releasing Legion XIV. The crash was so rough, the ground shook.

The mouth on the dragon head mounted on the chest opened up and began to gather energy in its jaws.

"EL DRAGO CERO!" Showa roared.

The Dreigon Head fired a blast that disintegrated Legion XIV's weapons as they howled in pain.

"Was that seriously a 'Cero'?" Gaim asked Showa.

"Gaim, your turn!" Showa prompted.

"OK!"

Great Dragon King Gaim landed and charged at Legion XIV as they were recovering and got back to their feet. Gaim commanded the heroic titan to strike with the Dragon Lance, hitting Legion XIV in the chest with an explosive slash. He then drove the Dragon Lance forward, piercing Legion XIV right in the chest. He withdrew the lance and hit Legion XIV in the face with a shield bash.

"Now, shall we finish this?" Showa offered as all their platforms lit up.

"And this time we do it for good," Ifrit said. "And if he gets up again, we just do it again and again until he can't anymore!"

[FULL CHARGE!]

"OK, let's do it!" Gaim concurred.

[SOIYA! ORANGE SPARKING!]

The three co-pilots fed their own energy through their individual platforms to charge up Great Dragon King Gaim's most powerful attack.

"GREAT DRAGON KING EXPLOSIVE FINISH!" Showa, Ifrit, and Gaim shouted as their combined form fired a powerful beam from the Dreigon Head.

"YOU WON'T FINISH ME THAT EASILY!" Shiro screamed. "HORROCHI INFINITY FIRE!"

The Orochi heads all fired their elemental blasts at full power and the opposing beams crashed into each other. The resulting shockwave knocked everyone down as the two giants engaged in an epic beam struggle for dominance.

"YOU WILL ALL DIE HERE!" Shiro screamed from within Legion XIV as he poured more power into his attack. He held the power of 666 Horrors. He could not be beaten here!

The beams pushed against each other and it looked like Legion XIV's beam was winning the struggle as their beam started to closing in on Great Dragon King Gaim. Ifrit, Gaim, and Showa struggled to fight but were showing signs of exertion as they tried to push back against Legion XIV. The beam struggle was straining the gestalt's stability and it was threatening to break apart.

"Not a chance!" Alan shouted as he used his ring to encase everyone in a green energy dome that transported them straight into Great Dragon King Gaim's cockpit.

"Huh!?" Gaim gaped as he spun around and saw the cockpit crowded with everyone. "You're all here!"

"Shinichi," Alan said as he stepped forward. "Let's take this sucker down. Show him that when heroes unite, nothing is impossible."

"Right!" Showa agreed. "Everyone, focus! Focus your power! Let's bring this monster down!"

The Shoku Warriors, Armored War Gods, Draco, Ryukendo and NEO-NUMBERS all glowed with energy that filled the cockpit and they all shouted as they focused their power into Great Dragon King Gaim.

"ALL LEGENDARY HERO ETERNITY FINIIIIIIIIIIIIIISSSSHHHHHHHHHH!"

The power of Great Dragon King Gaim's beam intensified, firing beasts, fruits, trains and Rider symbols that successfully pushed back Legion XIV's Horrochi Infinity Fire, winning the beam struggle.

The massive demon released a loud death cry as the giant gestalt warrior's beam blasted straight into the shrieking demon as they were obliterated by the blast.

"NOT AGAAAAAAAAAAAIN!" Shiro screamed as he was consumed by a massive explosion. The All Legendary Hero Eternity Finish was also powerful enough to vanquish the 666 Horrors contained within the Blade of Legion which was vaporized as well.

Great Dragon King Gaim stood victorious.

Alan wore a proud smile while everyone cheered at their victory.

"Looks like we'll have no more trouble here tonight."

And a new legend was born here tonight as well.

After the battle, Shinichi, Nagata and Ryuji were back in their civvies along with the other Riders. With Kirikaze vanquished, there was little reason for Ryuji to stick around. He had seen all he wanted to see and even helped beat a Horror. He was satisfied with this trip. It was also time for Shinichi to go and he took back the Showa Rider powers before he left.

While many people had died tonight, Kirikaze's demise still prevented more deaths and this world avoided a terrible fate tonight. Still, Shinichi could not leave it at that. He decided to use his chronokinesis to bring back the people Kirikaze/Shiro had killed. While he could not revive the people they had devoured, he could at least undo the deaths of the ones whose bodies were left. He also used his powers to undo all the collateral damage that happened during their battle.

It was an awesome sight to see someone being able to bring back the dead. Such a thing could only be done by a god.

Shinichi didn't think much of it. It was just the usual for him. It was his duty to undo all this damage the best he could.

"Hey, Natsu." Nagata approached the Ultimate Steel.

"Yeah, Nagata?" Natsu replied.

"Thanks for saving me earlier."

Natsu looked confused.

"What are you talking about?"

Nagata appeared confused from the response.

"Huh? You know, when Kirikaze was about to kill me."

"Sorry, man. That wasn't me."

"So if it wasn't you, then who was it?"

"Alright, everyone, back in the phone booth! Let's go! Let's go! Allons-y!" Alan called the Armored War Gods to return them to their respective territories. He also needed to take the NEO-NUMBERS, Draco, and Ryukendo back to their proper places. "Shinichi, come on!"

"Just a moment!" Shinichi answered his brother before addressing Ryuji. "Hey, Ryuji!"

"What is it?" Ryuji asked impatiently.

"I know right now you think you need to be the strongest."

"I don't think I need to be the strongest, I know I must," Ryuji interrupted.

"Right, and I know why. But honestly, I think she'd appreciate having you there with her even if you weren't the strongest," Shinichi advised, patting Ryuji's shoulder. Ryuji bristled at the touch but did not pull away.

"I'll think about it," Ryuji replied.

"Oh, and I was told to give this to you," Shinichi said while handing Ryuji a Rider Pass.

"What's this?" Ryuji asked as he took the pass and examined it. It was gold with an infinity sign on it.

"It'll help you when you face something truly vicious." It was all Shinichi could say without giving too much away.

Ryuji cocked an eyebrow at the cryptic message and then shrugged.

"Thanks. See you around."

"We'll see you again!" Loki waved.

Nagata approached Shinichi as Ryuji walked back to his train.

"So, guess this is goodbye then," Nagata said to Shinichi as the NEO-NUMBERS started to enter the TARDIS.

"My offer still stands," Shinichi said to the Blue King as he pointed to the TARDIS. "Just step inside and we can take you and the others back home. Whaddya say?"

Nagata considered it for a moment then shook his head. He had made his choice and resolved to stick to it to the very end.

"No, I'll stay," Nagata declined. "This is my home now."

"Well, in that case, here's a gift from me to you," Shinichi said as he handed Nagata a Lockseed with Kamen Rider Ichigo's face in the center and surrounded by the faces of the rest of the Showa Riders - the Showa Rider Lockseed.

"Whoa." Nagata was astounded as he looked at it then back at Shinichi. "You sure about this?"

Shinichi nodded.

"I got a feeling that you might need it in the future."

Nagata smiled, grateful for the present.

"Wow, OK. Thanks."

"Alright, sayonara then!" Smiling, Shinichi waved and went into the red TARDIS and the door shut. The TARDIS made a warping sound as it dematerialized and vanished.

VWOORP!

VWOORP!

VWOORP!

"How can they all fit in that thing?" Chou'un wondered as the TARDIS vanished. From the outside, it did not look like it had that much space inside.

"Bigger on the inside, most likely," Nagata answered. It was like a clown car, probably.

Ryuji was about to enter the DynoLiner which had separated from its mecha combination and returned to its default mode. The Shoku Warriors were still awed at the sight of the time train, especially after it had transformed into a giant iron warrior.

"So, where are you headed now?" Nagata asked curiously, fighting the urge to ask for another ride on the train.

"Well, the Multiverse is a huge place. I need to find more powerful warriors out there that I can challenge to a fight," Ryuji said.

"Can I ask, why do you wish to become stronger?" Kanu asked.

"It's so I can see her again," Ryuji answered cryptically as he turned to enter the train with Loki. He paused for a moment to look at Nagata. "Hey, Oda, keep getting stronger. You're going to need your strength for what's coming."

"Huh, what do you mean?" Nagata questioned but Ryuji ignored the question as the door closed. The DynoLiner trumpeted as a portal appeared in the sky. Train tracks formed and the train rode on the tracks and flew into the portal which vanished a moment later.

Meanwhile, a cloaked female figure watched them from afar before she turned and walked away. Her cloak swept slightly aside to reveal a SengokuDriver around her waist with a Ringo Lockseed docked in the Drive Bay.

"We'll meet properly soon, Naga-kun."

Ryuji sat in the dining car of the DynoLiner with an oddly somber expression. He was strangely quiet too.

"What's the matter, Ryuji?" Loki asked as he poured Ryuji a cup of coffee.

"Not sure. Just have this weird feeling that something's missing," Ryuji said as he scanned the interior of the dining car. "Has it always been this quiet?"

"It's always just been us onboard," Loki confirmed. "I think you're just feeling a bit homesick. Maybe it's time we ended this trip and return home."

"Yeah, home. Back to Kotonoha."

She had been kept waiting long enough.

Shinichi and Alan had just dropped off Hideyoshi and Kenshin. Fuyu and Natsu were dropped off earlier to rejoin their performance troupe who was on the road at this time. Now, only Masataka Miyamoto of the AWGs remained to be dropped off.

The NEO-NUMBERS, Ryuki and Neko were elsewhere on the ship. The twins were likely taking advantage of the food fabricator to make them a huge meal. The NEO-NUMBERS were also exploring the immense interior of the time-space ship.

"So, to Son Go, right?" Alan asked.

"Actually, I was hoping you could take me back to my world for a little bit," Masataka stated. "There's a couple of people I was hoping to check up on."

"OK," Alan complied as he entered the coordinates for Masataka's home universe and the era. "Right, here we go."

Suddenly, the TARDIS shook and alarms blared lightly. Shinichi caught the railing around the console to maintain his balance while Masataka nearly fell but he caught a grip of the console as he fell forward before he accidentally bumped his head on it.

"What's wrong?" Shinichi asked.

"Hold on." Alan put on his specs and grimaced as he looked over the data on the screen. "Well, that's not good."

"What is it?" Masataka asked as he rubbed his head while adjusting his glasses to peer over Alan's shoulder.

"Masataka, did you make a deal with someone or something that would prevent you from going back to your world?" Alan questioned calmly.

"Oh," Masataka realized as he recalled what Chosen had told them. "Yes, it was Chosen. He was able to send us back to the Three Kingdoms but on the condition that we would not be able to come back to our world."

"That's why she went crazy!" Alan concluded. "Whatever deal you made prevents my TARDIS from taking you home!" He looked regretful. "I'm sorry. I'm so sorry. I don't think I can take you home."

"Then how about we contact ARMOR?" Shinichi asked. "Maybe they can help?"

"We could try," Alan said. "But, well, this seems like something really powerful, like god level."

"God level?" Masataka asked. When he thought about it, Chosen's ability to turn up and provide them with whatever they needed did seem miraculous. It would make sense that he could be some divine entity masquerading as a flamboyant bodybuilder who did not possess a shred of shame.

"So, if ARMOR can't do it and your TARDIS can't do it then Masataka and the others are stuck where they are," Shinichi realized.

"Yeah, that's kind of it," Alan said. "Really sorry, Masataka."

"Look, it's fine," Masataka sighed sadly. "You said you can't bring me back home but can you at least go without me and check on my brother and my grandfather?"

"Sure," Alan said. "After we drop you off in Son Go."

"Thank you."

The TARDIS reappeared in Masataka's office and he exited it. Looking back, he watched the phone booth vanish before his eyes.

"This really is a strange universe," Masataka remarked.

Alan just dropped the NEO-NUMBERS off where he had picked them up before sending Ryuki and Neko back where he found them. The two had been covered in food. The rough tumble the TARDIS had taken must've spilled their food all over them.

"So these 'Armored War Gods' are meant to be in that world and there's nothing we can do about it?" Shinichi asked his brother as the TARDIS flew through the time vortex.

"Exactly," Alan confirmed. "We just have to let things play out this time."

"I could report them to ARMOR and let them sort it out," Shinichi suggested.

"Well, you could, but that world needs them. You saw that for yourself."

"You know, come to think of it, you could've easily beaten that thing with one punch," Shinichi realized. As the Emerald Sentinel, Alan Smith was an incredible powerhouse. In fact, he was such an incredible powerhouse that he was pretty much OP.

"I know I could've. I just didn't want to steal your thunder," Alan answered. "So, what's it like fighting alongside Uncle Ryuji?"

"Well, he hasn't changed much, has he?" Shinichi remarked.

"Too true," Alan confirmed. "Did you give him the pass?"

"Yeah, I did," Shinichi answered.

"Good, then the 'bootstrap paradox' loop is maintained."

The Infinity Pass that Shinichi had given to Ryuji had originally been given to Shinichi by Ryuji. So, in a few years from this Ryuji's perspective, he would later give the pass to a past version of Shinichi, thus continuing this repetitive cause and effect loop.

Shinichi's own existence was attributed to a similar paradox too, strangely enough.

"Funny how that turned out, huh? I got that pass from Ryuji after he originally got it from me and so I could give it to a past version of him," Shinichi commented, amused by the scenario. "Time travel is weird."

"So, where to next?"

"Could you send me back to ARMOR first? I need to report that this hunt was successful," Shinichi requested. "Then maybe we can pick up Rena and the others for a trip to Planet Barcelona."

"OK, setting coordinates for ARMOR, in the King's Terminal, in the Sands of Time," Alan said as he set the coordinates. "And up, up, and away we go!" He pulled the lever and the red telephone box shot into the time-space vortex for their next destination...and probably their next great adventure.

While the heroes had bid each other farewell, Shiro was revealed to have survived the vanquishing of Legion XIV. He stood in the distance, watching them while making sure to hide his presence so he would not be caught. He felt that his current body would not last for much longer. It was the price he had to pay for carrying all those Horrors within him. By becoming their host, he was fated to die along with them.

However, death was only a mere inconvenience for him. He had died before and still returned stronger than ever.

This would be no different.

"Enjoy your victory, for now, 13. But as long as you live, I will always come back," Shiro Juuyon swore.

Those were his last words before his body crumbled to dust.

The Femme Fatales watched as the Rinki flowed into Dai Shi's tomb. Shiro had made good on his promise. Now they were even closer to reaching their goal of fully reviving their lord Dai Shi.

"So, is it time?" Hebihime asked.

"Yes," Shirokumahime smiled. "Once we have the Seal of Heaven, we can begin the Great Sacrifice."

"THE END"

KRC: Finally finished! I wrote this like 4 years ago and it was pretty much stored in my Google Drive cloud ever since. I don't know why I left it there. I know I wrote it for a reason, but I just forgot about it, I guess. But, after finished Season 6, Volume 2, I decided to look through my specials and found this. After reading it, I decided to give it some revisions which included separating it into multiple chapters to make it into a special miniseries. Now, this chapter had some things that appeared in my past works:

-Showa Ascalon DxD appeared in Chapter 121 of Kamen Rider X Green Lantern: "Last Ditch Attack! Final Evolution."

-Dyno King appeared in the Kamen Rider Days Volume 1: "Magical Heart OVA with a Twist."

-Nagata using the Ultra Orange Lockseed for the first time since Destiny of the Armored War Gods: "Awakening the Ultra Power".

There's also the fact that Alan Smith, the Sentinel, now has a TARDIS similar to the Doctor's from Doctor Who. It takes the form of a red phone booth.

I guess I just wanted to write a fun and awesome crossover with these powerhouses. I mean, yeah, it's published a bit too late since we're in Season 6 and this should've gone up between Season 4 and Season 5, but it's better late than never in this case.
