Hello, everyone! PHANTOMKNIGHTMARE47 here, with the first chapter of a new version of my crossover between My Hero Academia and the Kamen Rider franchise, specifically Kamen Rider Amazons, AKA Amazon Riders. It's called: My Hero Academia: Amazon Riders. The plot of the story goes like this: Izuku Midoriya, AKA Deku is busy trying to relax after his adventures, when he and his friends have defeated the Shie Hassaikai and the Humarise, both groups who wanted to eliminate Quirks from the world, and feels as if he could take it easy, although he's struggling with PTSD following the death of the Pro Hero, Mirai Sasaki, AKA Sir Nighteye, who died during the raid on the Shie Hissaikai base. However, Izuku learns that Professor Kyudai Garaki, AKA Daruma Ujiko had created a new version of the Amazons Cell, and is injecting this new bio-weapon into Villains and inmates of Tartarus, turning them into Amazons that attack and eat innocent people. Izuku encounters Stain, who has become an Amazon based off of a Japanese Hornet, and is critically injured and nearly eaten, until the surviving Amazon Rider, Haruka Misuzawa, AKA Kamen Rider Amazon Omega arrives, and kills Stain/Hornet Amazon, and manages to get Izuku to the hospital. Once there, Haruka volunteers to save Izuku with a blood transfusion. The result: Izuku is turned into a new kind of Human Amazon that has the physicality of an Amazon, but without the need to feed on humans. Now, in order to exterminate the New-Type Amazons before they murder and eat innocent people, Izuku is given a Neo AmazonsDriver, and becomes U.A City's own Amazon Rider, Kamen Rider Amazon Zeta. Now, Izuku balances his life as a student of U.A High and being a Human Amazon, defending U.A City from these monsters. Along the way, Izuku finds himself gaining a harem of lovers, composed of fellow female U.A High classmates and female Professional Heroes.

Can Izuku and co. save U.A City from the outbreak of Amazons? If so, then grab a soda, pop some popcorn, order a pizza, and get ready to find out, as we take the ride in:

Chapter 1: Izuku The Human Amazon!

A long time ago, the discovery of superpowers, or Quirks was made, in China, where a baby started emitting a brilliant light. There were different kinds of Quirks, Emitter, Transformation, and Mutant. There were two different kinds of people who used their Quirks, such as the Professional Heroes, who defended innocent people, and Villains, who tormented innocent people. There were also Vigilantes as well, with some Vigilantes having lost their Quirks. However, some people did not have Quirks of their own. They were dubbed as Quirkless.

One such Quirkless youth was a young man named Izuku Midoriya, who dreamed of becoming a great hero, like his idol: The "Symbol Of Peace", Toshinori Yagi, AKA All-Might. However, Izuku was sadly born Quirkless, and was bullied on a regular basis by his rival, Katsuki Bakugou, whose Quirk made his sweat a nitroglycerin-based explosive compound. However, after saving Bakugou from a sludge-based supervillain, Izuku was scouted out and chosen by All-Might himself, and trained his body to withstand the power of All-Might's Quirk, One For All, which could stockpile strength, and afterwards, Izuku willingly ingested a strand of All-Might's hair. However, All-Might's body was deteriorating due to a mortal injury, limiting his time in his empowered form to the point he could lose One For All for good. After acing the entry exams, Izuku was accepted into his dream school: U.A High School, where he, alongside his classmates in Class 1-A, trained to become the world's next great superheroes.

Izuku and his friends fought against villains, such as the League Of Villains, and it's lieutenant, Tomura Shigaraki, the Shie Hissaikai, and it's leader, Kai Chisaki, AKA Overhaul, a man who wanted to purge Quirks from the world, The Humarise and their leader, Flect-Turn, who wanted to 'save the world' by erasing Quirks, because they believed in Daruma Ujiko's Quirk Singularity theory.

Location: U.A City, U.A High School, Boys Dormitory

Date: March 7th, 2024

It shows a young man in a dormitory decked out in various All-Might memorabilia. He had green hair, green eyes, and four freckles each in a diamond shape on both of his cheeks. This was Izuku Midoriya, AKA Deku. Izuku had dreamed of becoming a great hero, much like his idol, Toshinori Yagi, AKA All-Might, but his dreams were crushed when he learned from the doctor that he was one of several people who were born 'Quirkless'. However, after he helped save his rival, Katsuki Bakugou from a sludge-themed villain, Izuku was scouted by All-Might, who had Izuku train his body to withstand the power of All-Might's Quirk, One For All. After his training was done, Izuku willingly ingested a strand of All-Might's hair, and became the ninth and current user of One For All. After passing the written and physical exams, Izuku was able to get enrolled into U.A High-School, where he studied to become one of U.A City's next Pro Heroes.

'Things have been going somewhat okay, after all our adventures, going up against foes like Shigaraki, Chisaki, Flect-Turn, Nine, Wolfram, and other villains from U.A, America, and beyond.' thought Izuku, as he remembered his and his friends' adventures, having been to the United States, where he met David Shield and his daughter, Melissa, and several American Pro Heroes, and the times he and his friends fought against villains such as Tomura Shigaraki, the lieutenant of the League Of Villains led from the shadows by All For One, the Shie Hissaikai, and one of it's leaders, Kai Chisaki, AKA Overhaul, who wanted to destroy Quirks, viewing them as a 'disease', and Flect-Turn and his group, the Humarise, who believed in Daruma Ujiko's Quirk Singularity Theory, and also wanted to 'save the world' by erasing Quirks, Nine, a villain whose Quirk allowed him to control the weather, and was given a duplicate Quirk of All For One, but his weather manipulation Quirk was doing extreme cellular damage to his own body, and Wolfram, a villain that could control metal who wanted to use David Shield's Quirk Amplification device for himself, and other foes to name a few.

"It's been a while since mine and my friends' last few adventures. I kinda wish that Sir Nighteye was still around." said Izuku. He was saddened by the fact that during Class 1-A's mission to save a girl named Eri from the clutches of the Shie Hissaikai, one of the Pro Heroes, Mirai Sasaki, AKA Sir Nighteye, had sadly been fatally wounded by one of Overhaul's attacks, and died of his injuries in the hospital afterwards.

"Here's hoping that things are somewhat peaceful, with Chisaki and Wolfram in prison." said Izuku.

Meanwhile, it shows the lead scientist of the League Of Villains, Dr. Kyudai Garaki, AKA Daruma Ujiko, having worked on something. What he was working on was a new and improved weaponized variant of the Amazons Cell that was created by the late Professor Jin Takayama, AKA Kamen Rider Amazon Alpha.

"Soon, I'll turn the entirety of the Pro Hero community into Amazon Food, and there's nothing that can stop me!" said Dr. Garaki. He is revealed to have injected Chizome Akaguro, AKA Stain The Hero-Killer with the new Amazons Cell, and in a plume of smoke, Stain had transformed into an Amazon based off of a Japanese giant hornet.

"Success!" said Dr. Garaki, chuckling darkly. He then sent out the transformed Stain to cause havoc.

Later, we see a figure riding in on a stylized motorcycle. This was Haruka Mizusawa, AKA Kamen Rider Amazon Omega. Haruka was an Amazon who was infused with Human DNA from Reiko Mizusawa. As a result, Haruka grew to see Reiko's daughter, Mizuki as his own sister. He was given drugs and routine check-ups to keep the Amazons Cell in his body in check, one day, he skipped his check-up, and transformed into his Amazon Form for the first time in two years. He was given an AmazonsDriver, and became known as Kamen Rider Amazon Omega, and he helped the Nozama Peston Service in hunting down and exterminating Amazons that ate innocent people. He later used a Neo AmazonsDriver to transform into Amazon New Omega, and he also faced off against Einosuke Midou, AKA Kamen Rider Amazon Neo Alpha, and after one final fight, laid Jin Takayama, AKA Amazon Alpha to rest before heading off to parts unknown.

"This must be U.A City." said Haruka, taking notice of this. He then looked to see Stain as the Japanese Hornet Amazon stalking Izuku. 'Oh, no…' Haruka gulped, as he sped off on his Junglaider.

Later, it shows Izuku having seen Stain transform into the Japanese Hornet Amazon, and was shocked.

'Did…Did Stain just turn into some kind of monster!?' Izuku gasped in his mind, shocked by this. He then entered a fighting stance, and then started doing jumping-jacks. Due to ingesting a strand of All-Might's hair, Izuku also gained six other Quirks aside from One For All. The one he was currently using was Fa-Jin, which was used by one of One For All's past users, Bruce. This Quirk allowed Izuku to build up kinetic energy via repetitive actions, and store it up for later usage. He then leapt into the air, did a somersault, and came down with an axe-kick.

"FAUX 100%! MANCHESTER SMASH!" Izuku roared, as he tried to attack Stain, only for the transformed villain to grip his ankle, and slam him to the ground. He then opened his maw and mauled Izuku.

"HEY!" roared a voice similar to Adrien Agreste, as Haruka arrived. Haruka attached his AmazonsDriver to his waist, and twisted the grip on the right.

[OMEGA]

"AMAZON!" Haruka bellowed, as there was an explosion of energy, as he transformed into Amazon Omega, and fought against the Hornet Amazon as Izuku watched. Amazon Omega then gripped the grip on the left side of his AmazonsDriver, and turned it into a sickle. He then twisted the grip on the right.

[VIOLENT BREAK]

Amazon Omega then swung his sickle into the Hornet Amazon's shoulder, and tore it wide open. The blades on Amazon Omega's left gauntlet extended, and he twisted the grip once again.

[VIOLENT PUNISH]

Amazon Omega then lunged, and lopped the Hornet Amazon's head clean off of it's body. The Hornet Amazon dropped to the ground, and dissolved into a black sludge.

'Shit. He got maimed pretty bad. I'm gonna need to get him to a doctor.' Amazon Omega thought, as he got Izuku onto his bike, and drove off.

Later, it shows Izuku on life-support at the Central Hospital, with Izuku's mom, Inko with a worried expression on her face, alongside some of Izuku's classmates, Eijirou Kirishima, AKA Red Riot, Mina Ashido, AKA Pinky, and Tenya Iida, AKA Engenium II.

"Holy shit, so some monster basically maimed Izuku?" said Mina, shocked.

"Yes, and he's in critical condition. He'll need a blood transfusion." said the doctor.

"I'll volunteer," said Haruka, offering to help save Izuku's life. Haruka laid down, and the blood transfusion bag filled up with some of Haruka's blood, and then it was injected into Izuku.

"Thank you, sir." said Mina, bowing in respect. "You got a name?"

"Yes. My name is Haruka Mizusawa, otherwise known as Kamen Rider Amazon Omega." said Haruka, introducing himself. "I've arrived at U.A City to investigate some attacks related to monsters known as Amazons in this city."

"Is that what the monster that tried to eat my son was?" said Inko, scared.

"Yes. It was a Japanese Hornet Amazon that was originally Chizome Akaguro, AKA Stain The Hero-Killer, but I stopped him before he could harm Izuku even further." said Haruka.

"Bless you, Mr. Mizusawa-san." said Inko, hugging Haruka. "Wait, won't Izuku be one of those Amazons too?"

"Yes, but a new kind of Human Amazon that doesn't eat people." said Haruka, explaining everything. "The Amazons Cell in me will bond with the Quirk Genes inside of Izuku, turning him into a new kind of Human Amazon with the mentality and physical appearance of a Human, but with all the physical capabilities of an Amazon, and he can even safely pass on his genes without the offspring being a living biohazard."

(Author's Note: I am well-aware of Human-Amazon hybrids being considered living biohazards, but this is an AU, so Izuku will be able to have Human-Amazon hybrid kids without them turning into living biohazards.)

"Oh, thank Buddha." said Inko, relieved.

"He'll be needing this to combat the Amazons." said Haruka, as he set a Neo AmazonsDriver and a syringe next to Izuku's table. "It's what I used to become New Omega, like what Jin's son Chihiro used to become Amazon Neo."

"Huh. Neat." said Eijiro, amazed.

Later, as Izuku awoke, he had an omurice for breakfast, and got to his feet. He noticed that his physicality was even more advanced. He then looked at the Neo AmazonsDriver and syringe.

"A belt?" said Izuku, as he picked it up. "There's a note attached to it."

Izuku, there's something you should know:

My name is Haruka Mizusawa, otherwise known as Kamen Rider Amazon Omega. And I'm the man who saved your life.

There's something you should know: The head scientist of the League of Villains has replicated the Amazons Cell created by the late Prof. Jin Takayama, AKA Kamen Rider Amazon Alpha, and is weaponizing it as a means of wiping any and all Pro Heroes worldwide. We can't let that happen.

Which is why I commissioned David Shield to construct a Neo AmazonsDriver of your own, so that way, you can deal with the Amazons that attack U.A City.

I wish you the best of luck.

~Haruka.

Izuku now had a determined look on his face. And he grabbed the belt and syringe. As he headed out, he looked to see a Junglaider with lime-green optics. He then got a news report of there being what appeared to be a giant beehive with some Amazons based off of killer bees conjoined to an abandoned apartment complex. He then climbed onto his Junglaider and drove towards it's location.

Later, it shows two of the Pro Heroes, Enji Todoroki, AKA Endeavor, who was the father of Izuku's classmate and friend, Shoto, and Keigo Takami, AKA Hawks, who were fighting against a group of Worker Bee Amazons.

"Crap! There's too many of these buggers!" said Hawks, as one of them tried to attack from behind, but Hawks morphed some feathers from his wings into a pair of dual swords, which he used to slash it apart.

Later, Izuku arrived, and attached the Neo AmazonsDriver to his waist, and took out the silver-colored Armament Manifestation-type Amazons Injector syringe into the slot holder on the belt, and pressed down on the button. The eye on his Amazons Driver glowed golden orange.

[ZETA]

Izuku's eyes started glowing yellow, as he panted heavily, and then he uttered one word:

"AMAZON!" Izuku bellowed, as there was an explosion of energy. In Izuku's place was an armored figure that wore a green bodysuit with a red variant of Amazon Alpha's battle-scar pattern. His gauntlets and boots were a merger between Amazon New Omega and Amazon Neo. His helmet was also a merger between Amazon Omega and Amazon Neo, with Amazon Omega's optics and horn. His optics were golden orange in color. This was Izuku's own Amazon Rider form, Kamen Rider Amazon Zeta.

Amazon Zeta looked to see some Killer Bee Amazons charging at him, so he fought them in hand-to-hand combat. He snapped one's arm in half at the elbow, and tore it's arms off with his bare hands before twisting it's head 180 degrees perpendicular from the rest of it's body, breaking it's neck. He then pressed down on the syringe on his belt.

[EXTENDING BLADE]

A blade appeared on Amazon Zeta's right arm, and he slashed and stabbed one of the Killer Bee Amazons with it, before tearing it's head in half. He then raised and lowered the slot-holder and syringe.

[AMAZON BREAK]

Amazon Zeta then sliced the last of the Killer Bee Amazons in half at the shoulder with his blade. The blade disengaged, as Amazon Zeta entered the hive of Killer Bee Amazons.

Later, in the hive, Amazon Zeta looked to see several other Killer Bee Amazons with their queen. The Queen Bee Amazon was bigger and taller than the others, and looked to be wearing a 'gown' made of a hardened exoskeleton.

"You must be the one leading these Amazons." said Amazon Zeta, scowling underneath his helmet.

"That's right. And I plan on turning both the civilians of U.A City and it's Pro Heroes into food for myself and my servants!" said the Queen Bee Amazon, as he extended some Baraka-style forearm blades.

"I'm not gonna let that happen!" said Amazon Zeta, as he fought against the Queen Bee Amazon in hand-to-hand combat.

(BGM: "DIE SET DOWN" by Taro Kobayashi plays)

Amazon Zeta was using snake-style Shaolin Kung-Fu, striking at the Queen Bee Amazon, and countering her attacks. He then delivered a powerful knife-hand chop to the monster's throat, bruising her windpipe. He then grabbed the Queen Bee Amazon's forearm blades, and with a sharp tug, tore them off by the roots. The blades on Amazon Zeta's right gauntlet extended, and Amazon Zeta raised and lowered the slot-holder of his Neo AmazonsDriver.

[AMAZON PUNISH]

With that, Amazon Zeta lunged, and slashed the Queen Bee Amazon with the blades, as there was a loud, sickening *SCHLOCK!* as the attack connected. The Queen Bee Amazon got to her feet, but crumpled to the ground, having been sliced in half at the shoulder. Both halves fell to the ground with a sickening *THUD!* and melted into black sludge.

"Good fucking riddance." said Amazon Zeta. He then looked to see Endeavor and Hawks looking at him, shocked.

"Jesus Christ!" Hawks gasped, exclaiming the Lord's name in shock. "You freaking mauled that monster!"

"Yes. Hopefully, the ranks of the other Killer Bee Amazons will fall apart, now that their queen is as good as dead." said Endeavor.

"I'll take care of the remaining stragglers." said Amazon Zeta. "Afterwards, you need to burn down the hive."

"Got it." said Hawks, as he and Endeavor nodded in confirmation. Amazon Zeta then headed off to find and kill any remaining Killer Bee Amazons.

'I never would have guessed that one of Shoto's classmates, Izuku Midoriya, would be behind the mask of this new Amazon Rider.' thought Enji, taking notice of this. 'I know that he and his friends will not only destroy these Amazons, but also apprehend the man who's behind this new Amazon outbreak.'

The pro hero then watched as Amazon Zeta fought and killed the various other Killer Bee Amazons. Once that was done, Amazon Zeta got onto his Junglaider and drove off.

"Now, to finish off the hive and any other surviving Amazons." said Endeavor, as he ignited the Killer Bee Amazon hive, burning it to the ground.

Later, it shows Izuku speaking with Haruka, as well as a now-Quirkless Toshinori Yagi, AKA All-Might and Inko.

"You kicked some serious tail out there, Izuku." said Inko, as she kissed her son's cheek.

"Thanks, Mom." said Izuku, as he hugged his mother.

"Izuku, there are other Amazons that are still out there in U.A and beyond, and it's going to be up to ALL of us in order to stop them." said Haruka. "And we're going to make sure that Kyudai Garaki, the man who recreated and is weaponizing the Amazons Cell is held accountable and imprisoned for his actions."

"Agreed." said Izuku. 'One thing's for certain: my friends and I are gonna be in for one helluva ride.' he thought.

(End of Chapter 1)

Next Time, on My Hero Academia: Amazon Riders: Izuku adjusts to his new life as a new type of Human Amazon, and is balancing his life as an Amazon Rider and a student of U.A High School, hoping to become U.A's own Amazon Rider. He later learns of there being a string of disappearances related to a Shinto temple in U.A as a villain who became a Mosquito Amazon is impersonating a monk and is behind the disappearances. Can Izuku stop this nightmare? Get ready to find out in Chapter 2: The Temple Of God.

Whew! That took me a couple days to type up. Also, I have some sour news for fellow Weekly Shonen Jump fans. On March 1st, Akira Toriyama, the mangaka for Dragon Ball, Dr. Slump, Sand Land, Dragon Quest, Chrono Trigger and Blue Dragon has sadly died at the age of 68 due to acute subdural hematoma. His son, Sasuke, will be taking over as creator of Dragon Ball.

Rest easy, Mr. Toriyama-san. And may the power protect you, even in death.
