Hello, everyone. PHANTOMKNIGHTMARE47 with the first chapter of an old fanfiction I used to write that I'm rewriting. In this case, it's Kamen Rider Night. Basically, my OC Self, Nathan Ralls, is turned into a Cyborg-type Kamen Rider as a means to fight against Giganidas and his forces, all while travelling to other worlds.

It cuts to a young man with chin length dark brown hair, a youthful clean-shaven face, coffee brown eyes, a black short-sleeved shirt, blue jeans, and black sneakers reading Harry Potter & The Sorceror's Stone. This was Nathan Ralls, an autistic student of the Winter Bluffs Spectrum Center. Ever since his mother, Esmerelda, a female soldier, was killed in action, and his father was traveling abroad as a jazz saxiphonist, he lived with his older brother, Chance, his younger sister, Danna-Lynn, and their cousin, Justin Kase.

"Hiya, Mom." murmered Nathan as he knelt down to pray "I know it's been a while since you've sacrificed yourself to save your friends in Arabia, but how are you doing in Heaven? I still talk to Dad on video-chat while he's traveling abroad as a jazz musician. I'm doing a little okay, I suppose. I want you to know that me, Danna-Lynn, and Chance all miss you so much it hurts."

"Hey, little bro." said a voice similar to Ray Manchester/Captain Man from Henry Danger, Danger Force, and so on as an older version of Nathan with stubble on his chin, and darker hair arrived in Nathan's room. This was Chance Alexander Ralls, Nathan's older brother, and a newspaper editor. With him was a fourteen year old girl with elbow length brown hair, brown eyes, and rectangular glasses dressed in a tomboyish anime girl fashion. This was Danna-Lynn Hope Ralls, Nathan's younger sister, a high-school sophomore.

"You praying?" said Danna-Lynn, sounding like Leni Loud from The Loud House, looking at her older brother

"Yeah, sibs." said Nathan as he sniffled "Sorry, guys. My eyes are still a little red, and-"

"Hey, it's gonna be A-OK, little bro." said Chance "We're all gonna miss Mom. C'mon, Justin and I ordered pizza to celebrate his latest victory in the courtroom."

"We also bought a chipotle salad, so you'd still get some greens in ya too." said Danna-Lynn

"Thanks, sibs." said Nathan as he followed his siblings to the kitchen

Narration by Nathan:

My name's Nathan. Nathan Ralls. I live with my older brother, Chance, who is a newspaper editor, my younger sister, Danna-Lynn, who is a high school sophomore, and our cousin, Justin Kase, a prosecutor, in our apartment in Winter Bluffs. I attend the spectrum center there with my friends, and I have bad luck with women, to be honest. I live a normal life with my sibs and cuz, but I feel like my everyday life is gonna change in more ways than one.

Chapter One: Beginning of NIGHT

It cuts to vast reaches of space, where an alien spaceship has entered Earth's orbit. This was the Nightmare Fortress, the starship commanded by alien lifeforms known as Giganoids, beings who wanted total control of the known universe.

The Giganoid sitting on the throne was Giganidas. He resembled N-Daguva-Zeba from KR Kuuga, with the head, forearms, and shoulders of Overlord Inves Baron from KR Gaim. He had emerald green skin with gold accents, as well as Perfect Cell's face, as well as large draconic wings similar to Linehalt from Bakugan, and red eyes with purple sclera. This was Giganidas, the most diabolical warlord of the galaxy.

Giganidas's subordinates were composed of Zarkor, the swordsman, Kazdon, the assassin, Bargon, the general, and Jyrax, the jester.

"Report, Bargon." said Giganidas, sounding similar to Baron Draxum from Rise Of The Teenage Mutant Ninja Turtles

"We are over Earth's orbit as we speak, milord." said Bargon, indicating to the screen

"Excellent." said Giganidas "Soon, we Giganoids will reign supreme over Humans, Mobians, Faunus, and Monsters altogether!"

"We already have a multitude of Mutaroids, Lord Giganidas." said Jyrax "Why not send them all?"

"No, no." said Giganidas "All these monsters running rampant on this planet is more than I myself can handle."

"I well send MetaMantis to deal with the populace of Earth." said Zarkor, revealing a kaijin that resembled the Berotha Magia crossed with Guyver-Zero.

"Go forth, MetaMantis!" said Giganidas as a magenta beam sent the monster down to Earth "Raise Hell on Earth, and destroy all you can!"

Suddenly, a man noticed MetaMantis land near the city, and the monster in question growled lowly

"What the hell are YOU supposed to be?" said the man, poking and prodding the mantis kaijin, only for MetaMantis to slash him in half, prompting everyone else to scream in terror

"Yes! Run, pathetic monkeys!" said MetaMantis "Nobody can save you now!"

Elsewhere, a scientist at the Winter Bluffs Institute was watching this on TV. This was Emmet Ralls, Nathan, Chance, and Danna-Lynn's uncle, a scientist at the institute.


"I need to find someone to stop this monster, before he does any further damage!" said Emmet

Later, it cuts to Nathan at the gym in a sparring match with one of his friends, Matthew Woods. Matthew resembled a young Joseph Joestar crossed with Little Mac, he stood at six-foot-eight, had red hair, and green eyes. He was really muscular too. Nathan's other friends, Shawn Maxwell and Gage Johnson were there, watching the whole fight

"You must mean buisness this time, Nathan." said Matthew, sounding similar to Jin Kazuma "I've never seen you use dragon-style kung-fu before."

"It's time I tried something different than Muay Thai." said Nathan

"Kick his ass, Nate!" said Shawn, sounding similar to Haida from Aggretsuko's official English dub

"Whup his butt, Matt!" said Gage, sounding similar to Blaine from Totally Spies, prompting Shawn to look at him with an annoyed look "What? Am I not allowed to root for the other guy?"

Suddenly, the four friends heard a scream come from downtown, and they got out of the gym to see MetaMantis wreaking havoc

"What the crap!?" Nathan blurted out "What in the heck is THAT!?"

"Some sort of alien bug or something?" said Matthew

"Well, it's causing mass mayhem!" said Gage "We gotta stop it! If not us, then who will!?"

"That's not the best option, Gage." said Nathan with a nervous look

"I know. But it's my choice to make." said Gage. With that, Gage charged towards MetaMantis, and landed a few jabs to the mantis monster's body, then to it's face.

"Jeez, is your exoskeleton made out of lead or something!?" said Gage, until MetaMantis sent him skidding back with a smack

Shawn and Matthew were shocked to see a Mantis monster easilly beat Gage with one attack, until Shawn charges with his pocket knife to try and stab MetaMantis, only for the blade to snap off on contact

"My exoskeleton is as dense as iron!" said MetaMantis as he struck some pressure points on Shawn, knocking him out cold

"Was that mantis-style kung fu!?" said Matthew, alarmed to see a kaijin with a martial-arts style

"You've certainly done your homework." said MetaMantis, as Matthew charged at him with a lead pipe, and swung it across MetaMantis' head, only for it to bend on impact.

"Hey, ugly!" said Nathan "Lay off of my friends, and try fighting me for a change!"

"Well then, we've got a fighter." said MetaMantis as Matthew looked worried

"Nathan, I'm not sure that fighting this guy's the best choice." said Matthew, looking worried for his friend

"I know. But it's my choice to make." said Nathan as he raced towards MetaMantis, and landed a few blows to his torso, only for MetaMantis to slash one of his arm-blades across Nathan's chest, Nathan held in his screams

"Next is going to be your head." said MetaMantis "Don't think you'll be carried out of this battleground in one piece!"

Suddenly, Emmet arrived, holding a laser pistol that he fired at MetaMantis "Keep away from him!"

"The hell are you supposed to be!?" said MetaMantis

"Someone who's gonna help this boy and stop your master once and for all!" said Emmet as he grabbed Nathan's unconcious form, and carried him off


Elsewhere, Matthew, Gage, Shawn, Chance, and Danna-Lynn were in a room in the Winter Bluffs Institute of Science, waiting for Nathan to come out, until Nathan came out looking a little better

"How's he doing, Uncle?" said Chance

"He's doing OK." said Emmet "How I saved his life is simple: I turned Nathan into a cyborg."

"A CYBORG!?" Matthew, Gage, Shawn, Danna-Lynn and Chance blurted out, shocked to hear that Nathan had machine parts inside of him now

"How's that possible?" said Danna-Lynn

"Well, quoting from The Million-Dollar Man, 'We have the technology.'" said Emmet "His physical attributes have been boosted to higher levels, and I planted a gemstone of power called the Night Stone inside of him. If he's gonna fight that monster again, he's gonna need an upgrade."

"What kind of upgrade?" said Matthew

"Nathan here is gonna be a Kamen Rider." said Emmet "A Kamen Rider known as Kamen Rider Night."

"Kamen Rider Night?" said Matthew

"My Rider Motif is a Japanese giant hornet." said Nathan. Until he saw a girl his age that resembled Korra mixed with Kaname Kururugi. She had tanned skin, some muscles, H-cup breasts, and magenta, cyan, and yellow hair. This was Marceline Watson, a girl who Nathan had feelings for since childhood

"Marcy!" said Nathan as he hugged his childhood crush

"Hiya, Nate." said Marceline, sounding like Mary Test from Johnny Test.

"Marceline's been Nathan's crush since middle school." said Danna-Lynn, smiling

"We've set you up with some Rider Machines, Nate." said Emmet, revealing a Yamaha YBR 750 RR themed after a Japanese hornet, and a car that resembled Shadow's car, Dark Reaper, mixed with Tridoron.

"The motorcycle is called Night Cruiser." said Emmet. "It's got a conciousness of it's own, can change it's tires to suit any turrain, and has front mounted laser blasters. The car is called Machine Yozora. It can go at mach ten, has front mounted laser cannons, and can become either a jet fighter or a speedboat."

"Thanks a bunch, Uncle Emmet." said Nathan, hugging Emmet.

"I can get you from point A to Point-B in two shakes of a lamb's tail, Nate." said Night Cruiser, as Nathan hopped on.

"MetaMantis is attacking Byakko Square." said Emmet "Kick his tail, kiddo!"

"You got it, Uncle!" said Nathan as he drove off.


At Byakko Square, MetaMantis was fighting against armed S.W.A.T soldiers, who were armed with rifles

"Open fire!" said the S.W.A.T captain, as the soldiers opened fire, only for the bullets to bounce off

"Looks like we might have to resort to melee combat." said the captain as they charged, only to get tossed around like cookie-dough

"What weaklings!" said MetaMantis "I demand a stronger opponent!"

"YOU'VE GOT ONE, ASSHOLE!" Said a voice as Nathan arrived on Night Cruiser, and took his helmet off.

"Didn't I put you in critical condition last time?" said MetaMantis

"I got better." said Nathan "And I have a new trick up my sleeve."

With that, Nathan did the same movements that Kotaro Minami did to become Kamen Rider BLACK, and one word came to Nathan's mind

"Henshin!" said Nathan as he was enveloped in a bright neon green light. In Nathan's place was an armored figure that resembled BLACK RX BioRider, with the helmet of Super-One. His wrists, ankles, knees and elbows were grey, while his armor was black, and his optics were neon green, like the gemstone in the center of his belt

"The hell are you!?" said MetaMantis

"I'm Kamen Rider Night!" said Night "Ally to good, nightmare to you!"

"Damn you!" said MetaMantis, getting pissed off "I won't stand for this!"

With that, Night and MetaMantis duked it out in hand to hand combat, punching and kicking and chopping, Night was landing a miryiad of blows on MetaMantis

"Damn you!" growled MetaMantis "ZOMBORGS!"

With that, a group of grunts resembling X-Borgs from PR Super Megaforce with the heads of Dustards from KR Fourze arrived.

"Oh now that's just cheating!" Night groaned as he fought against the Zomborgs left and right, tossing them around like cookie dough

"I'm the villain!" said MetaMantis "I'm allowed to cheat if I want to!"

"Oh yeah!?" said Night "I'll still kick your ass!"

With that, Night began knocking Zomborgs around left and right, and sent one flying towards MetaMantis, who cut it in half

"HOW IS THIS HAPPENING!?" said MetaMantis

"You mad, bro?" said Night, trolling the mantis kaijin

"I will eradicate you!" said MetaMantis as he charged at Night, and they started fighting hand to hand again

(Cue Song: "Genjyou Destruction" by SPYAIR)

Night did a leg sweep, and a strong left hook to MetaMantis' head, before he delivered a hand chop that smashed MetaMantis' arm blades

"Th' hell!?" MetaMantis blurted out

"Rider Punch!" said Night as he delivered a right hook, his fist shining green, sending MetaMantis skidding back. Night then got a running start, and jumped into the air, doing a flying kick as his boots shone neon green

"RIDER KICK!" said Night as the kick connected

"DAMN IT AAAAAAAAAAAAAAAAALLLLLLLLLLLLLLLLL!" bellowed MetaMantis at the top of his lungs as he collapsed and then exploded, like every Kamen Rider kaijin does when they're defeated

The crowd of people cheered

"Look, that armored superhero saved us!" said a kid

"Who are you?" said a man

"I'm Night. Kamen Rider Night." said Night "And my motto's this: If there's a monster attacking your hometown, I'll be there to stop it for good!"


Elsewhere, at the Chaos Fortress, Giganidas was so angry, he crushed his wine glass in his hand.

"No. No. NO-!-!-!" Giganidas snarled "How can MetaMantis lose to an Earthling with anxiety issues that can become a KAMEN RIDER!?"

"Milord, please calm yourself!" said Jyrax

"No matter, we'll conquer the Multiverse, and make all life in the multiverse bend to our will." said Giganidas "And all Mobians, Humans, Monsters and Faunus will bow before the Giganoids!"

Later on, Nathan and his friends were shown a ship akin to the Nubian from Star Wars, but modified

"This ship will get you guys anywhere in the multiverse you need to go." said Emmet "And it looks like your first stop is in the world of Demon Slayer: Kimetsu No Yaiba."

"Looks like we'll be teaming up with Tanjiro and his friends to help slay some Demons." said Matthew

"You'll need these." said Emmet as he handed Nathan, Matthew, Gage, Shawn, Chance, and Danna-Lynn each a sheathed katana. "These are Nichirin Blades, the weapons meant for slaying Demons. They're made out of Sunlight Crimson Ore and Sunlight Crimson Iron Sand, which is found in the Sunlight Mountain. They're also called Color-changing Swords, because they change color depending on the first person who unsheathes them."

With that, Nathan faced his friends and siblings "OK, guys. On three. One. Two. THREE!"

With that, they all drew thier Nichirin Blades at once, Nathan's turning cyan, Danna-Lynn's turning magenta, Marceline's turning ultramarine, Chance's turning apple green, Gage's turning red, Matthew's turning vermillion, and Shawn's turning lavender.

"Nathan's got this trait called Ice Breathing." said Danna-Lynn "I have Flower Breathing, Chance has Storm Breathing, Matthew has Hellfire Breathing, Shawn has Poison Breathing, and Gage has Eclipse Breathing."

"We'll use our Breathing Techniques to slay any Demon that attacks innocent people." said Nathan as the friends boarded the craft, with Justin and Emmet watching with a smile
