Prologue: Beginnings! Rise of the Ganmanoise!
Thirteen years ago...
Years had passed since the defeat of the Ganmeisers, a group of seemingly immortal gods who ruled over a place known as the World of the Ganma. However, over the course of 99 days these gods were destroyed by a trio of men called the Kamen Riders: Ghost, Specter, and Necrom. These three heroes believed in the infinite possibility of humanity, allowing them to overcome hardship after hardship in their war against the invading Ganma.
With the power of infinity, the Ganmeisers were destroyed one-by-one. No matter how much they attempted to improve the situation, the Riders always came up on top. The Ganma Emperor, too, eventually fell to the infinite potential of the Kamen Riders. And with that, the war ended. There was a sparkling future for humanity and the remnants of the Ganma.
Then it happened. The Ganmanoise rose. These creatures of mass destruction could turn anything they touched into ash. Once again, that trio of men would have to arise to save the world from these mysterious creatures.
Alarms went off and people retreated as another wave of Ganmanoise had arrived. However, two motorcycles whizzed past the retreating people. They eventually came to a stop in front of the approaching monsters. Three people got off of them, removing their helmets. All three of them were older men: Takeru Tenkuji, Makoto Fukami, and Alain. The three Kamen Riders who had foiled Emperor Adel's plot for his so-called utopia.
Upon their arrival, they could only really look at these creatures. Colorful and filled with an animalistic instinct to eliminate humanity.
"So these are the new Ganma?" Alain said, putting his helmet onto the back of Makoto's motorcycle.
"Seems like it, bigger and uglier than what I thought they'd be." Makoto replied, marking the obvious difference between the Ganma and these new monsters. The original Ganma were about the size of an average human, but these things were of all different sizes and shapes. However, they all shared one similar feature. A Ganma Eye.
"We'll beat them. We always do." Takeru replied, taking out a large gold belt buckle, the Eyecon Driver G. "Let's do this."
"Right." Makoto and Alain agreed, both donning their respective transformation items: another Ghost Driver and the Mega Ulorder. Alain, for a moment, felt a lingering sense of doom.
"Everyone… help me out one last time!" Takeru said, placing the belt on his waist and hitting the button on the side to activate the belt. Makoto took out a black Eyecon and clicked the button on the side to activate it, before dropping it into his belt and closing it. Alain removed an artificial looking Eyecon and hit its activation button as well, causing it to ring out, before placing it into his wrist based transformation device.
Gat~chirimi~na! (Kotchinikina!) Gat~chirimi~na! (Kotchinikina!)
Batchirimiro! Batchirimiro! Batchirimiro!
Standby. Yes Sir!
All three men took a stance in their normal pre-transformation pose before all three shouted out at the same time.
"Henshin!" The Three Riders yelled out together, as a great flash occurred, causing the advancing Ganmanoise to fall back a little. Fifteen different parka ghosts emerged from Takeru's belt and flew around. For Makoto and Alain, only a single parka ghost emerged, their personal ones. A transient suit appeared on all three of them, before their respective parka ghosts flew toward them, allowing the Riders to don their actual forms.
Zen Kaigan! Kengō, hakken, kyoshō ni ō-sama, samurai, bōzu ni sniper! Dai~ Hen~ge~!
Kaigan: Specter! Ready, Go! Kakugo! Doki Doki Ghost!
Tengan: Necrom! Mega Ulord! Crush the Invader!
The three Riders looked forward at their enemy, a huge army of advancing monsters. Specter and Necrom put down their hoods ad each took out their weapon.
"I'm going to let my soul burn brightly!" Ghost announced. "Let's go!"
Necrom and Specter nodded, as they gripped their matching weapons and charged the Ganmanoise. The giant monsters barely stood a chance, despite their large imposing size and ability to turn anything to carbon dust… That didn't even phase the three Riders. Specter landed in the middle of a group of them and began shooting at them with his trusty Gangun Hand, eliminating them almost immediately.
The sudden depletion of numbers caused the Ganmanoise to rile up. Like animals, they began attacking without question. Jumping around to avoid being hit, Specter began to float in midair and take shots at the Ganmanoise. Specter eventually landed and was hit in the back, causing him to fall back toward a wall.
"Makoto!" Ghost yelled out. He quickly hit the lever on his belt, allowing him to summon out the Legendary Heroes.
Nobunaga! Rasshai!
Houdini! Rasshai!
The embodiments of Oda Nobunaga and Harry Houdini joined the fray in order to assist their normal user, Specter. Both Nobunaga and Houdini held a copy of the Gangun Hand. The two helped Specter up. Houdini just laughed and used his back wings to fly around, taking shots at the Ganmanoise. Nobunaga, stayed on the ground and assisted Specter in taking out the ones that were in the closest area.
Likewise, on the other side of the current battlefield, Necrom used his Gangun Catcher to do much of the same. He rolled around on the ground, and shot at two of them, destroying them instantly.
"So only our weapons can destroy them?" Necrom asked himself. "Must be." He got back to his feet and continued to fire at them from a distance. However, he would then get closer and use the clubbed fist on the end to blunt force them to death. A tentacle knocked Necrom into one of the closer Ganmanoise. He shook his head as shoved the gun into the monster and fired, killing it immediately.
Ghost wielded his Sunglass Slasher and used that to take out the Ganmanoise that he was dealing with. Like a master swordsman, he managed to easily take out the monsters that stood in his way. He leapt up and kicked a group of Ganmanoise, eliminating them nearly immediately. Raising a fist, he punched another one causing it to explode. He charged up energy into his sword and spun around, releasing a circle of energy that killed off the ones that were closest to him.
He hoped to take a breath, however that was easily stopped by a group of oncoming Ganmanoise. The three Riders regrouped together.
"There's more of them." Specter stated. "No matter how easy they are to destroy with our power, they might end up tiring us out before we can finish them off."
"Let's try getting rid of them all at once then!" Ghost announced, Houdini and Nobunaga returning to their armor plates on Ghost's suit.
"Hopefully this works!" Ghost yelled, cycling through every single Hero.
Musashi! Edison! Robin Hood! Newton! Billy the Kid! Beethoven! Benkei! Goemon! Ryoma! Himiko! Nobunaga! Tutankhamen! Houdini! Grimm! Sanzo!
Let's go! Zen-in shūgō! Mega Omega Formation!
Specter agreed and hit the lever on the left side of his Driver.
Dai Kaigan! Specter! Omega Drive!
"Looks like we have no choice." Necrom said, flipping the Mega Ulorder and hitting the button on top, causing a small drop of green liquid to hit the top of the Eyecon.
Dai Tengan! Necrom! Omega Ulord!
Ghost floated up into the sky, as a large symbol appeared behind him. Specter and Necrom both leapt into the air, their own symbols appearing behind them. Ghost joined as all three Rider stuck out their legs and went flying at the hoard of Ganmanoise.
"Souls are eternal and undying!" Ghost exclaimed, as all three Riders came in contact with the remaining hoard. A brilliant flash occurred, just as an explosion enveloped the area. The
Ganmanoise had no chance, as the three Rider's combined power eliminated every single Ganmanoise. Each and every Ganmanoise was reduced to nothing but carbon ash. A large layer of dust came down from the sky like snow.
CLACK CLACK CLACK
In the dust fell some items. Two Ghost Drivers, the Mega Ulorder, and three Ghost Eyecons: two blank and the third, Necrom's Eyecon.
Among the dust a woman appeared, wearing a black cloak. She was completely hidden under it, except for a glowing red symbol on her chest. The silence was broken.
"Threat eliminated."
Song 01: Amazing! The Rise of Ghost!
"What do you mean you can't make it?"
"This is… Zwei-Wing!"
"The Ganmanoise!"
ZESSHOU KAIGAN! FINAL OMEGA DRIVE!
A/N: I wrote this a long time ago like three or so years ago. It was in 2016, it was one of my favorite fics of the time, but I purged this account of the story when I was walking away from fanfiction. Now it's back, and will update regularly once all the chapters are up. I hope you all enjoy!
