However, that life is turned upside-down, when aliens known as Giganoidians, attack Earth with the intention of taking over the world and other worlds much like it. Nakashima fights one of the kaijin created by the Giganoidians known as a Darkmare, a kind of bio-organic monster known for causing problems for mankind. However, the members of the government-funded group known as the Allied Multiverse Protection Squad, or AMPS for short, led by Raymond Thompson III, save Nakashima's life by performing surgery on him, making him into a cyborg warrior meant for combatting the Darkmares.
Now, Nakashima, along with his friends, travels through various worlds as a means of defending them from Giganidas's monsters. And along the way, Nakashima starts getting a harem of lovers.

He had help from Akira Date, AKA Kamen Rider Birth, and others to name a few.
Years later, in Japan, a young highschool student named Gentaro Kisaragi, who had a delinquent look to him, but a drive to befriend everyone, became known as Kamen Rider Fourze, and fought against monsters called the Zodiarts, which were people that became kaijin based around the 88 modern constellations.
Time passed, and we were introduced to a young man named Haruto Souma, who became known as Kamen Rider Wizard, and fought against monsters called Phantoms, which were born from humans who succumbed to despair. Haruto had an ally in the form of Kosuke Nitou, AKA Kamen Rider Beast.

Shinnosuke had allies in fighting the Roidmudes, such as Gou Shijima, AKA Kamen Rider Mach, and an antiheroic Roidmude known as Chase, AKA Kamen Rider Chaser. The three Riders fought the Roidmudes, as well as Gou's father, Dr. Tenjirou Banno, and the Singular System.
Time passed, and a young man named Takeru Tenkuji, a ghost hunter, was killed by interdimensional monsters called the Ganma, and became a Ghost himself. Now given a 99-day time limit to come back to life completely, Takeru must find the 15 Historical Figure Eyecons, and use them at the Monolith in the Daitenku Temple. To do this, Takeru had to become Kamen Rider Ghost, and fight against the Ganma. Takeru's allies were Akari Tsukashima, who believed in science, Onari, a monk of the Daitenku Temple, Makoto Fukami, AKA Kamen Rider Specter, Makoto's sister, Kanon, and Prince Alain, AKA Kamen Rider Necrom.

The Riders faced off against the Bugsters, a new kind of computer virus that infected humans, as well as Kuroto's father, Masamune Dan, AKA Kamen Rider Chronos, who was an index-case just like Emu.
Following the defeat of the Bugsters and Masamune, in another area, Japan had been divided into Touto, Seitou, and Hokutou, after Pandora's Box was found on Mars, causing an event called the Sky Wall Crisis. An organization called Faust had caused monsters called Smash to appear, and the robot soldiers of Hokuto, Seito, and Touto, the Guardians, were reprogrammed into serving Faust. However, the people of Japan had a common hero named Sento Kiryu, an amnesiac scientist who originally went by Professor Takumi Katsuragi, but he had his memories altered by an alien being named Evolt. Sento used the Build-Driver and the Fullbottles to become Kamen Rider Build, defeating the Smash before extracting the Fullbottle Essence from people. Sento had help from Ryuga Banjoh, a prison escapee framed for a crime he didn't commit. Ryuga was given his own Build-Driver, and became Kamen Rider Cross-Z.

Sogou had an unlikely ally in the form of the Resistance Fighter, Geiz Myokouin, AKA Kamen Rider Geiz. Woz became known as Kamen Rider Woz. One day, while fighting the Time Jackers' leader, Swartz, as Another Decade, Sougo became Ohma Zi-O when Geiz was killed, and after defeating and killing Swartz, the timeline had been altered.
Time passed, and a company called HIDEN Intelligence, manufactured androids with artificial intelligence known as HumaGears, to improve the lives of the people of Japan. One day, when HIDEN Intelligence's old CEO, Korunosuke Hiden, had passed away, Korunosuke's grandson, Aruto, a struggling standup comedian, had succeeded his late grandfather as the company president. When the terrorist hacker cell, MetsubouJinraiNET started hacking ordinary HumaGears, and causing them to become Magias, Aruto became the heroic Kamen Rider Zero-One, defending humanity from the rogue HumaGears. Aruto had unlikely allies in the form of the members of the Artificial Intelligence Military Service, or A.I.M.S, specifically agent Isamu Fuwa, AKA Kamen Rider Vulcan, and technician Yua Yaiba, AKA Kamen Rider Valkyrie. Aruto had a rival in the form of Gai Amatsu, AKA Kamen Rider Thouzer, the CEO of ZAIA Enterprise, who had a hand in the awakening of the Ark, a malevolent A.I. But, Aruto and co. managed to defeat the Ark.
Following Aruto's adventures, a bookstore owner named Touma Kamiyama, who was also an aspiring author, had an encounter with monsters called the Megid, and in order to fight them, was given a Seiken SworDriver, and became known as Kamen Rider Saber, the Swordsman of Fire.

We now turn to a new chapter in history, where we meet a new Rider. This is the tale of…
仮面 ライダー星雲
KAMEN RIDER NEBULA!
Location: Winter Bluffs
Date: April 21st, 2023
We turn to a town located north of Domino City. This is the town of Winter Bluffs, home to 3 supermarkets, a wonderful school-district, a bookstore, a library, and 6 different bakeries and cupcake shops, with some using vegan ingredients.
We turn to see a young man with dark reddish-brown hair and emerald green eyes, wearing a black t-shirt under a white hooded jacket, indigo-blue jeans, red Nike sneakers, and white fingerless driving gloves. This was Nakashima Kazuma, a college student who lived with his aunt and uncle following the day his parents died in a car-crash when Nakashima was 10 years old. He was currently visiting his parents' grave.
"Hi, Mom. Hi, Dad." said Nakashima, sounding like Haruo Sakaki. "It's been a while, hasn't it? I've been doing OK in school, and I've been helping Auntie Retsuko and Uncle Yoshida out at home." he teared up a little. "Words can't describe how much I miss you guys, and how I wish you were still around." he sniffled. "I just wish things were different." he then laid a bouquet of flowers at their tombstone. "I love you guys, and I miss you very much."
He then got to his feet, and walked to his college apartment, until he looked to see a group of bullies harassing and bullying an elderly blind woman. This triggered Nakashima, knowing that he can't stand bullies.
"HEY, YOU SCUMFUCKS!" Nakashima snarled, as he stormed up to the bullies. "WHERE THE FUCKING HELL DO YOU HEARTLESS BASTARDS GET OFF, PICKING ON A POOR OLD BLIND WOMAN!?"
"Get lost, Boy Scout. You'll live longer if you don't get involved." said the thug, shoving Nakashima.
"Oh I'm fucking getting involved, alright!" said Nakashima. He then proceeded to whale on the thugs, he popped the first thug in the nose, shattering it like fine chinaware. As the thug reached for his face, Nakashima grabbed the thug's wrist, and broke it. Nakashima then kicked the second thug square in the balls, and knocked him down with a leg-sweep. The third thug lunged at Nakashima with a steel baseball bat, only for Nakashima to disarm the thug, and grab his arm, ready to break it.
"Please don't break my arm." the thug gulped, scared.
"No." said Nakashima, as he slammed his elbow down, breaking the thug's arm in two different places. The thug screamed like a goat, and Nakashima knocked him down. The lead thug then drew an army knife.
"YOU'RE DEAD MEAT, YOU LITTLE SHITFUCKER!" the leader snarled, as he rushed Nakashima with his knife. Nakashima then broke the leader's hands, and stabbed the knife into the lead thug's leg, drawing blood.
"GAAAAAAAAAAAAAHHHHHHHHHHHHHHHHH! HE FUCKING STABBED ME!" the lead thug yowled. His goons got to their feet.
"We'll remember this! Watch your back, you little washout!" said the lead thug, as he took off with his goons.
"And don't even THINK about coming back, unless you want your asses kicked again!" said Nakashima. He then turned to face the woman. "Are you alright, ma'am?"
"Yes. Thank you for saving me from those thugs, young sir." said the elderly woman. "Not a lot of you brave folks, who'd beat the snot out of someone to help save another these days."
"I'm the kind of person who looks out for the little guys, ma'am." said Nakashima, with a small smile. He and the elderly woman parted ways.
Nakashima's Narration
"My name is Nakashima Kazuma. I'm 21 years old. I'm a college-student, who majors in literature and art. I've lived with my aunt, a chef, and my uncle, a former soldier, following my parents' death in a car wreck. I live in an apartment with some of my closest friends. I never would have guessed there'd be actual aliens, or even other worlds aside from ours. Until now, it seems. This is my story."

Chapter 1: I Am The Child Of The Stars!
Nakashima headed to his college apartment, where he looked to see his friends and housemates, Daigo Kanezawa, Courtney Tezuka, Carter Tezuka, and Masato Hozuki. They have been close friends since childhood. Daigo had brown hair and chartreuse-green eyes, and wore a t-shirt themed after Kamen Rider Kuuga, indigo jeans, and white sneakers. Courtney and her brother, Carter, were Japanese-American twins. Courtney had strawberry-blonde hair and cyan eyes, and wore a Sailor Moon t-shirt, a magenta skirt, and purple ballet-flats. Carter had russet-brown hair and brown eyes, and wore a Gundam t-shirt, jeans, and white sneakers. Masato has black hair, indigo eyes, a jean jacket over an Attack On Titan t-shirt, jeans, and gray Nike sneakers.
"Hey, guys." said Nakashima, waving hello to his friends.
"Yo, Nakashima!" said Carter, as he and his childhood friend then did a knuckle-bump. "How goes it?"
"Good. I managed to save a blind old lady from a group of thugs." said Nakashima. "I dunno why some people are so horrible nowadays."
"I dunno, man." said Masato, shocked. The group then decided to get some studying in.
Meanwhile, in Earth's orbit, it cuts to an alien starship hovering over Earth. This ship was known as the Hell Fortress. This ship was owned by the Giganoidians, a race of aliens who wished to rule over the Earth, and other worlds like it. Onboard the craft was the warlord, Giganidas, the master swordsman, Zankord, the war general, Gextral, the assassin, Kenvardon, and the jester/royal fool, Gyrax.
Giganidas looked like Absolute Tartarus mixed with Overlord Inves Baron and Olympius. His body was emerald green, dark gold, and amethyst purple in color.
Zankord resembled Delu-Knight mixed with Absolute Titan, Jugglus Juggler, and Kamdor. His head looked like Kamdor's mixed with Villamax.
Gextral resembled Damaras mixed with Wreckmate and General Schwartz
Kamdor resembled Snide mixed with Ripcon, but wore armor similar to Deathstroke crossed with a Mandalorian
Gyrax resembled Reala crossed with Laughing Jack and Gork.
"Report, Zankord." said Giganidas, sounding like Baron Draxum in Rise Of The Teenage Mutant Ninja Turtles.
(Author's Note: Giganidas's VA is John Cena)
"We are in Earth's orbit, as we speak, my liege." said Zankord, kneeling before his master.
"Excellent. Soon, this world, and others like it will be under the control of us Giganoidians!" said Kenvardon.
"Now, which monster shall we send down to Earth, milord?" said Gyrax "We have several Darkmares at our disposal, so why don't we send them all?"
"No, my underlings, one monster at a time shall be enough." said Giganidas. "All these monsters released at once can cause serious problems." he then looked to see a humanoid biomechanical spider with six arms. "Ahh, Arachnitron shall do quite nicely." he then manifested the monster.
"Milord." said Arachnitron, as he kneeled before the Giganoidian warlord and his subordinates.
"Everyone, what I have here is a Darkmare that can spin a sticky webbing that's as strong as steel." said Giganidas. "He'll make short work out of humanity."
"Excellent." said Kenvardon, as Arachnitron beamed down to Earth.
This was being noticed by people who were affiliated with AMPS, the Allied Multiverse Protection Squad, a government-funded organization of soldiers, scholars, and scientists, dedicated to protecting all worlds from the likes of Giganidas and his forces. The leader of AMPS was a man named Raymond Thompson III, who came from a family of soldiers. Raymond had a square jaw with some stubble on his chin and cheeks, black hair, and indigo-blue eyes. With him was Professor Jeremiah Broslowski, a Jewish-American scientist who came from a family of Holocaust survivors who survived the events of World War 2.
"Are you seeing this too, sir?" said Jeremy, concerned.
"Yes. The Giganoidians are planning to take over our world and others like it." said Raymond. "We need you to find someone who's brave enough to take on threats such as these."
"Yessir." said a soldier. Jeremy, and a couple AMPS members then headed off into their Jeep, and drove off.
Later, it shows Nakashima and his friends heading back from their usual hangout, the Galaxium Cafe, which was an internet cafe crossed with a video arcade. Suddenly, Nakashima caught the whiff of smoke, and his eyes went wide with shock. A house was on fire. Nakashima doused himself with water, and rushed inside. Courtney and Carter then grabbed some fire-extinguishers, Daigo was helping get people to safety, and Masato was dousing the fire with water. Nakashima managed to bust down the door to a baby's bedroom, and managed to scoop the crying infant into his arms, and rushed back outside to hand the child to its parents.
"Bless you, young sir," said the woman. Suddenly, Nakashima heard a snarl, and looked to see Arachnitron arrive.
"Lookie what we have here. An insignificant little worm playing hero, my favorite." said Arachnitron, with a cold expression on his face.
Nakashima then entered a fighting stance, and managed to land some jabs on Arachnitron, but to little effect.
"My turn." said Arachnitron, as he then shattered Nakashima's left leg.
"AAAAAAAAAAAAAAAAAAAAAARRRRRRRRRRRRRRRRRRRRRRRRRGGGGGGGGGGGGGGGGHHHHHHHHHHHH!" Nakashima yowled, as he let out a gut-twisting scream of pain.
"Now for your arm!" said Arachnitron, as he shattered Nakashima's right arm. Nakashima wasn't able to stand up and run, or fight back, and at the rate things were going, he was about to be turned into a rotting corpse
"Who even are you?" said Nakashima, shocked.
"I happen to be a Darkmare, and the name is Arachnitron." said the monster in question. "Say your goodbyes, you worthless NINGEN!"
"Not on my watch, monster!" said a voice, as Jeremy arrived, holding a blaster-pistol similar to the guns used by Cyborgs 001 to 009, and shot Arachnitron with it.
"GAHHH! We'll meet again, Humans!" said Arachniterror, as he took off. Nakashima was lifted into a gurney, and the scientists got him into their jeep. Masato, Daigo, Carter, and Courtney then got into the jeep, and the vehicle drove off.
Meanwhile, onboard the Hell Fortress, Giganidas had taken notice of what had just happened, and scowled.
"This proves to be problematic." said Giganidas, having taken notice of this.
"What's the problem, milord?" said Zankord, surprised.
"It appears that Arachnitron's progress was impeded by a government-funded organization of dimension hopping soldiers, scholars, and scientists." said Giganidas, with a scowl.
"This proves to be a problem." said Gextral.
Meanwhile, in the home base for the IDDB, we see an unconscious Nakashima being operated on by Jeremy and his fellow scientists. He was being outfitted with cyborg enhancements, and cyborg augmentations to his right arm and left leg. They finished the operation by implanting a gemstone called the Cosmic Jewel inside of Nakashima's body. Then, once the operation was done, Nakashima woke up.
"Whuh…?" Nakashima groaned, as he slowly got up.
"Easy there, son." said Jeremy, as he helped Nakashima up. "You've been through literal hell."
"What the hell happened? Where am I?" said Nakashima.
"You're in our base. My name is Professor Jeremiah Broslowsky, but everyone calls me Jeremy for short." said Jeremy. "With me is my colleague, Doctor Jonas Bogard and his apprentice, Josh Taylor."
"Hello there." said Jonas, facing Nakashima. Ian had a lab coat over a science-themed "Bazinga'' shirt, jeans, and boots. He had black hair, gray eyes, and full-moon glasses. Josh had auburn hair, and chartreuse-green eyes, and was dressed similar to his mentor. Nakashima then got to his feet.
"That's odd. Normally, I wouldn't be able to stand up on a destroyed leg, or be able to move a damaged arm." said Nakashima, perplexed by this.
"Well, when that monster severely injured you, we performed surgery to save your life by outfitting you with cyborg augmentations." said Jeremy. "Long story short: In order to save your life, we converted you into a cyborg."
"Wait, WHAT!? You put machine-parts in me?" Nakashima blurted out, shocked by this news. "How were you able to do that?"
"Well, quoting from The Six-Million Dollar Man: "We have the technology"." said Raymond, as he walked into the room. "Hello there, Nakashima. My name is Raymond Thompson III, and I'm the leader of AMPS, which stands for Allied Multiverse Protection Squadron. We're a group of soldiers, scholars, and scientists dedicated to protecting this world and others like it from the forces of evil."
"So, you're an organization funded by the world government?" said Nakashima, with a curious look on his face.
"That's quite correct." said Raymond, as he introduced Nakashima to some more members of AMPS. "Right here is our field captain, Genjiro Shimada, and his son, Chosuke."
"Hello there, young man." said Genjiro, introducing himself. Genjiro had a square jaw, dark hair, and reddish-brown eyes. Chosuke had indigo-blue hair, green eyes, and wore a Hunter X Hunter t-shirt, jean shorts, and Nike sneakers.
"Yo!" said Chosuke, with a smile.
"And here is our newest arrival. May I be pleased to introduce our Lieutenant, Ayame Kanazawa." said Raymond, a woman who looked like Sakurako Hono crossed with Erza Scarlet arrived at the building. She had indigo hair styled in a fusion of Yang Xiao-Long from RWBY and Poison from Street Fighter, magenta-colored eyes, and was stacked, muscular, and busty, and stood at 6 ft. 9 in. tall.
"Hiya, Nakashima. My name is Ayame." said Ayame, sounding like Blair from Soul Eater, but more seductive in tone. "I'm new here."
"Uhhh, h-hi, Ayame." said Nakashima, blushing madly.
"Nakashima, we've called you and your friends here, because we need your help in stopping the Giganoidian Army from taking over this world, and others like it." said Raymond. "So, we saved your life by modifying you into a warrior who can defeat the Giganoidians and their monsters, the Darkmares."
"Nakashima, you have been chosen to become…Kamen Rider Nebula," said Jeremy.
"Kamen Rider….Nebula?" said Nakashima, perplexed. "Ummm, well, I don't wanna be themed after a bug, though."
"Not to worry. Your rider motif is a lion." said Ayame. Nakashima was then taken into a room, where he saw a modified 2023 HONDA CB400SF, with a lion's head at the front, similar to Brave Leon from Madan Senki Ryukendo, as well as a modified 2023 Lambhorgini Hurrican NEO with a lion motif.
"These are your Rider Machines, Nakashima." said Jeremy, showing Nakashima the vehicles. "The motorcycle is known as Stellar Striker. It has form changing tires, as well as front-mounted laser cannons, and the ability to enter a robot form."
Suddenly, the motorcycle transformed into a humanoid robot that was a human height. He resembled Cruise, but with a lion theme.
"Hiya, Nakashima." said Stellar Striker, "Anywhere ya wanna go, I'll get you there in a zim-zam second!"
"Stellar, no need to brag about yourself. Only I get to do that." said Jeremy. "Sorry, Nakashima. He's a tad conceited."
"It's understandable." said Nakashima, with a small smile.
"The car is known as Cosmic Hunter. It can change from a car into either a jet-plane or a speedboat-submarine hybrid, and it has front-mounted laser cannons and missiles." said Jeremy.
"In the words of Sonic The Hedgehog: Way past cool!" said Nakashima, with a smile on his face.
Suddenly, the group heard an alarm sound, and they saw the viewing screen, where they saw Arachnitron causing problems in the Business District.
"That's the monster I went up against!" said Nakashima, shocked.
"That would be Arachnitron, a bio-mechanical Kaijin known as a Darkmare." said Raymond, explaining everything.
"Time to kick some monster ass." said Nakashima, cracking his knuckles. Stellar then converted into his motorcycle mode, and Nakashima climbed on.
"Your transformation call is 'Ectophase Activate', much like how Prince Dex of Edinoi used to become Masked Rider, as a means of combatting the monsters of Count Dregon." said Raymond.
"Good luck, Nakashima." said Daigo
"Give that overfed spider Hell!" said Carter.
Nakashima smiled at his friends, and drove off.
Later, it shows the SWAT Team confronting Arachnitron. "FIRE AT WILL!" said a soldier, as he and his friends opened fire, only for their bullets to bounce off of Arachnitron's armored exoskeleton.
"Beat him up at will!" said another soldier, as the group tried to thrash Arachnitron.
"My turn! Monster Art: Cutting Web!" said Arachnitron, as he formed some ultra-sharp razor webbing to slash some of the SWAT team's skin, and severed some of their limbs.
"Face it, you overly-evolved monkeys, nobody can save you now!" said Arachnitron.
"That's where I most passionately disagree, jackass!" said a voice, as Nakashima arrived on his Rider Machine.
"Hey, you're that pleb I maimed!" said Arachnitron.
"Yeah, and I'm back, and ready to break your ugly face!" said Nakashima. With that, he did the same transformation poses as Kotaro Minami crossed with Ryo Murasame, as a belt formed on his waist.
[HENSHIN]
"ECTOPHASE ACTIVATE!" said Nakashima, as he transformed into Rider Form. He wore lion-themed armor that was colored similar to God Ryukendo, but the optics were golden-yellow in color.
"Masaka! This can't be happening!" said Arachnitron, shocked. "Who even are you!?"
"I am the Child Of The Cosmos." said Nebula, as he did the same poses as BLACK RX and ZX "Kamen Rider…NEBULA!"
With that, Nebula then fought against Arachnitron in hand-to-hand combat, the two traded punches and kicks. Arachnitron then spat out a shot of webbing at Nebula, who evaded the shots.
"Keep still, damn you!" Arachnitron snarled, getting frustrated.
"Not gonna happen, jackass!" said Nebula, as he then smashed his fist into Arachnitron's solar-plexus, making the spider Darkmare hack up blood.
"YOU LITTLE WRETCH!" Arachnitron roared, furious "You're gonna fucking SUFFER, you know this! You're gonna suffer, and you're gonna die screaming!" he snarled. "The only way you're leaving this place is in a fucking coffin!"
(BGM: "Vandalize" by ONE OK ROCK Plays)
"That's where you're wrong, jackass!" said Nebula, as he then fought against Arachnitron, with all his might. Nebula's right gauntlet glowed yellow.
"RIDER PUNCH!" said Nebula, as he then cracked Arachnitron in the jaw. Nebula then jumped into the air, and did a flying side-kick with both boots glowing yellow
"GALACTIC RIDER KICK! AIYAAAAAHHH!" went Nebula, as his kick connected, sending Arachnitron flying back
"DAMMIT AAAAAAAAALLLLLLLLLL!" Arachnitron bellowed, as he then exploded.
Nebula took a deep breath, and then exhaled. The other SWAT soldiers rushed up to Nebula.
"Thanks for your help." said a soldier.
"No problem." said Nebula, smiling under his helmet.
"You got a name, Kamen Rider?" said another soldier.
"My name is Kamen Rider Nebula." said Nebula, the lion-themed Rider introducing himself. "And my motto is: if there's a monster out there causing trouble, I'll be there to send it on their way to Hell!" He then did a selfie with the SWAT troopers, before heading off on his bike.
Meanwhile, on the Hell Fortress,, Giganidas was absolutely furious.
"NO! Our monster's been felled, and it's all because of a new Kamen Rider!" Giganidas bellowed, furious.
"Hmph. The Rider who fought and killed Arachnitron is green as fucking grass." said Gextral, scowling. "Barely any combat experience whatsoever."
"He could prove to be a worthy opponent, in due time." said Zankord.
"Nonetheless, we could always try again next time." said Kenvardon.
Meanwhile, back on Earth, the group were boarding a ship that resembled the Astro Megaship from Power Rangers In Space mixed with a Defender light-class corvette from Star Wars: The Old Republic.
"May I be pleased to introduce: The Nebulonius, our own dimension-traveling craft." said Jeremy, as everyone got onboard.
"I hope my auntie and uncle are OK with this." said Nakashima, worried about how his aunt and uncle would react.
"Not to worry, they've been informed ahead of time, and they're OK with it." said Raymond. "Plus, we asked your local college to fax you and your friends your homework, so you don't fall behind."
'Thank you, Jesus.' thought Nakashima with a sigh of relief.
"Our first destination on our trip through the multiverse is the universe of Totally Spies." said Jeremy. "We'll be helping the agents of the World Organization Of Human Protection, as well as the paranormal investigators of The Center in Beverly Hills, California."
Once everyone got onboard, the Nebulonius then lifted off, and flew through a dimensional portal.
