Author's Note: This is an idea I got from various Yu-gi-oh fanfics, which showed a different duel between random duelists chosen each chapter by the author or from the suggestions of the reviewers. Basically, I'm taking the idea and applying it to Kamen Rider fights.
Disclaimer: I don't own Kamen Rider.
Decade vs. G3-X
Reason: Tournament to determine the strongest Rider.
Tsukusa stood at one end of the large coliseum. He stared straight ahead, waiting for his next opponent to emerge from a shimmering white wall. Yuusuke, Natsumi, and Tsukikage watched from the otherwise deserted stands.
Deserted because as soon as the battle ended with his victory, Dai-Shocker's castle would rise up and the stadium would be reduced to rubble. Yuusuke and Natsumi could probably survive it, but then they would know he'd betrayed them.
No, he'd never been on their side in the first place. Amnesia or not, he'd always been Dai-Shocker's leader, destined to save the worlds and rule over them. Could he really do it though? Could he inflict suffering on the denizens of the worlds he'd journeyed through?
Tsukasa raised his head at the sound of a barrier opening. The shimmering white wall covered the opposite end of the arena. If he squinted, he could make out the shapes of buildings through the distortion. The hum of an engine filled the coliseum and an armored figure rode out of the barrier.
The Rider pulled his bike to a stop. He wore bulky blue armor. The lenses of his mask were two red orbs, a pair of metal antennae stuck out above these 'eyes.' He leaned his large white motorcycle down on its kickstand and dismounted. Only Tsukasa stood close enough to make out the lettering on his shoulder, but Yuusuke recognized the Rider, having spent a short span of time in the role.
Pulling the Ride Booker open, Tsukasa drew a card from it. He held it out, clutched between two fingers. He flipped the card around so the back faced his opponent. "Henshin!"
"Kamen Ride!" the Decade Driver droned as the card slid into it. A red holographic ring appeared around the white buckle. Tsukasa pushed the belt's sides in, closing the driver. The barcode-like symbol of Decade appeared in the center of the ring. "Decade!"
The symbols of the first nine Riders Tsukasa derived his power from appeared in a circle. Each emblem morphed into a shimmering grey silhouette, the nine shadows pulled back toward Tsukasa, overlapping on top of him and becoming his suit. The barcode hologram split into several red cards, which hovered up to Decade's helmet and inserted into it, becoming black lines through his mask, which turned magenta along with the grey areas of his suit.
"The next round," exclaimed the announcer. "Decade has been progressing well, but can he beat the mechanical precision of Kamen! Rider! G! 3! X!"
The announcer was starting to grind Tsukasa's nerves. He preferred the drone of his belt to the hyperactive stadium-filling voice.
Decade knew he could not give G3-X enough time to pull the large square box off the back of his motorcycle and convert it into the massive chain gun. The weapon could destroy an Unknown simply by laying thousands of rounds into it.
Sure enough, his opponent went right for the box. The clamps on it released and the weapon's owner entered the code on it.
Tsukasa charged forward, pulling the Rider Booker off his belt and pulling the handle back. He squeezed the trigger and unleashed a burst of gunfire. The bullets struck the chain gun, knocking it from G3-X's hands. Decade pulled the handle further back and a long thin blade unfolded from the Rider Booker. G3-X pushed a button on his bike and a compartment hissed open, he reached in and pulled out a large blue chainsaw.
He blocked Decade's sword and knocked it back. He swung his weapon and it buzzed across Tsukasa's chest armor. Sparks flew from the hit and Tsukasa dropped back. He landed on hard ground, rather than green linoleum. Rolling to his feet, Decade quickly surveyed his surroundings.
The arena's dimension warping had landed him in a forest this time. No, not a forest, he could see a concrete walkway a short distance through the trees. A park maybe?
G3-X took advantage of his momentary lapse in attention to pull another weapon from his bike. He aimed the large black handgun and pulled the trigger. Decade noticed just in time to roll to the side.
The blue Rider holstered his pistol, attaching it to his leg armor and pulled the handlebar off his bike, holstering that on the opposite side of the pistol. He took the chainsaw back into both hands and blocked Decade's sword.
He knocked the blade to the side and tried for another slash at Tsukasa's chest, but the magenta Rider leapt back. He rolled under another swing of the saw.
"I know what to do against you," Tsukasa said, holding up a card in his freehand. The Rider depicted on the card wore a navy suit with light grey armor. He inserted the card as he ducked under another swing.
"Kamen Ride! Blade!" the belt announced, releasing a blue rectangular screen with a stag beetle emblem on it. Decade dashed through the screen, emerging on the other side of it as the Rider shown on the card.
Tsukasa spun around to face G3-X. The blue Rider raised his chainsaw, while the transformed Decade held up two cards. He tossed the first into the Decade Driver.
"Attack Ride! Magnet!"
G3-X charged at the navy Rider as a blue projection moved from the white belt buckle and absorbed into his chest armor. Tsukasa pulled the buckle back open and inserted the second card.
"Attack Ride! Metal!"
A second projection absorbed into Decade's chest armor and a steel aura surrounded his form. The chainsaw slammed into his side and buzzed against the metal. G3 gasped and tried to pull his weapon away, but it stuck fast. Tsukasa meanwhile took advantage of the other Rider's mistake by raising his sword and slashing it across the defenseless Rider's chest armor twice.
His opponent stumbled back, letting go of his weapon. Decade pulled the Driver open and it ejected the Blade cards. Tsukasa's suit blurred red and black forming back into its original magenta, black, and white form.
G3-X drew his firearm and gripped the trigger. Bullets exploded against Tsukasa's chest armor. He stumbled back under the barrage before leaping to the side, taking cover behind a tree. He pushed the Rider Booker's handle back in, retracting the blade and returning it to gun mode. He dashed out from behind the tree, firing away at G3-X, who retaliated with his own shots. Decade avoided the shots, rolling to a stop behind another tree.
He peered around the trunk and watched as his opponent slowly stepped back towards his bike, gun trained on Tsukasa's hiding place. He wondered why the Rider would be heading for his bike instead of cover.
Unfortunately, Decade was about to find out. G3-X broke into a run for the motorcycle and slid to the ground, grabbing his chain gun. He punched in the code and the gun's handle pushed out of the box, while he swung up the barrel into place. He attached the handgun to the larger weapon and a hatch popped open. Pulling a red missile from the hatch, G3-X attached it to the front of the chain gun. Finally, he took hold of the handgun's trigger and leveled the weapon at Tsukasa's hiding place.
Tsukasa didn't think he simply reacted. Pulling the Rider Booker open, he grabbed a random card from it and inserted it into the Driver. "Kamen Ride! Kuuga!"
The black and red armor formed around Decade, replacing his helmet last with a black one bearing red lenses and a pair of golden horns. Tsukasa drew a second card and quickly tossed it into the Driver.
"Form Ride! Kuuga Titan!"
The missile launched with a pull of the handgun's trigger. It struck the tree and sent an explosion of fire and wood splinters at the changing Decade. G3 lowered his weapon to the side and stared at the smoking flames created by his handiwork. He gasped as a figure emerged through the cloud.
Decade stepped out of the haze, now clad in heavy grey armor with purple lines. The lenses of his mask changed purple. He still resembled Kuuga, just with more armor and a change in color scheme.
Tsukasa charged at his opponent, his speed hampered by his heavier armor. Still he reached G3-X before he could separate his two weapons and fire either one of them. He punched the Rider's helmet, knocking him to the side. His hand found its way to the handlebar-themed police stick and pulled it free of its holster.
The stick grew larger, much larger as Kuuga's inherent powers reshaped it into a massive grey broad sword. Decade slashed the weapon across the other Rider's chest, leaving a long slash mark in the armor, exposing the circuitry and wires underneath. Tsukasa got in a second slash before thrusting the sword forward, piercing G3's shoulder armor and knocking him back.
G3-X crashed down on the linoleum floor. With his armor too damaged to continue, Decade had been declared the winner. The white wall, which he originally arrived through, appeared and swept up the defeated Rider.
Decade stared across the arena, waiting for his next opponent…
Author's Note: I will take all proposed battles suggested by viewers into consideration, but I make no promises to use a battle and I will determine the outcome myself. If you have any problems with the way I conduct any of these fights I trust you'll be able to express your feelings in a comprehensive mature review and not just go "you suck!".
