Hey guys and gals, welcome to my newest story My Quartzer Academia! A crossover between Kamen Rider Zi-O and My Hero Academia.

This will be a replacement fic for dragon ball because it didn't seem very popular to you guys, don't worry I'll be dating the one-shot chapter with the extended version if you want to read this.

Anyway, why Zi-O and My Hero Academia is I already have my hero academia fic… this was the only one I could think of for Zi-O, and I have had a LOT of ideas for zi-o, which I'm kinda surprised no one thought of, not even that Zi-O revised guy.

So with that said, let's do this! although spoilers because you may wanna at least watch Kamen rider build to understand some parts in this.

Disclaimer: I don't own anything except my OC's.


Dream

Third-person P.O.V.

We see in outer space two earth's slowly about to collide with each other, with a red line of energy between the two.

Within that red line of energy we see two people fighting one was a red alien, with a red device around his waist with a lever on it named Evolt and the other a red and blue warrior, Kamen rider build or Sento Kiryu who also had a device around his waist that looked the same as Evolt's but black.

The two were fighting to secure the creation of a new world.

Build was knocked to the ground, as he reverted to his base from Rabbit Tank.

"And You're back to your first form…" Evolt laughed "Guess that proves me right" he smirked, as Build slowly got back up.

On his belt was a black machine with two bottles on it, one red with a picture of a rabbit on it and one blue with a picture of a tank on it.

Suddenly the rabbit bottle began Shinning until it changed from red to gold, making Sento smirk "You sure about that?".

He then pulled a black and red sword with a slot that looked like it could fit in several of those small bottles.

He then moved the hilt of the blade so he could slot it in the golden rabbit bottle.

RABBIT!

He then took out a silver dragon full bottle and slotted that in as well.

DRAGON!

Build moved the sword back up, as it was surrounded by gold and silver energy.

IT'S A PERFECT MATCH!

He then entered a fighting stance, making the alien laugh hysterically.

"Hahaha! That hilarious, do you think that attack is gonna work?!" Evolt yelled.

"…I do" Build said, as he rushed towards Evolt who was about to hit him but then Build jumped up into the air at great heights.

PERFECT MATCH BREAK!

Build then swung his sword downward, getting a successful slash at the alien before he slashed again.

"Because Banjou and I…" he said, before turning around and swinging again "ARE The BEST MATCH!".

Evolt staggered back, as blue sparks began coming from his body "What?! My body is…!"

"Sento… you smacked me awake!" Another voice, Banjou Ryuga, said from Evolt's body as he started holding Evolt back.

"Banjou, you bastard!" The alien roared, as Sento removed the two bottles from his belt.

Sento smirked, as he pulled up the two bottles "Now then… shall we start the final experiment".

He then started shaking the two bottles, as equations started going through his mind before he opened his eyes and twisted the bottle's caps and slotted them into his driver.

RABBIT!

DRAGON!

He then started spinning the lever on the driver, as several pipes came from the belt forming into two half bodies for each bottle.

Are you ready?

"Build up!" Sento said as the half bodies slammed into him forming a new armour which was followed by a funky toon.

The rabbit half of the suit was now gold instead of red, and the tank part of the suit was now replaced with a silver dragon-themed form.

BEST MATCH!

"We've found the winning formula!" Sento said as he started spinning the lever before jumping into the air.

"Raaahhh!" Evolt roared, as he spun his lever before jumping in the air towards Sento.

READY GO!

FEVER FLOW!/ VORTEX ATTACK!

"RAAAHH!" Evolt roared, as his fist glowed with red energy while Build sent a flying kick towards him. The wasteland they were in dissolving as they did.

The two collided, as Sento kicked Evolt in the chest sending them both flying towards the ground.

Sento soon returned to his rabbit tank form, as he continued to kick Evolt "THIS IS THE END!"

"YOU THINK THIS IS THE END!" Evolt growled, gripping his leg "LIKE HELL IT IS! YOU PUNY HUMANS!"

The was a ginormous explosion sending an energy wave throughout the universe, before everything went to white, with the sound of a clock being echoed throughout.


Opening: Heroes from Ultraman Chronicle Geed and Zero


The scene starts with the sound of music as we see the images of several heroes and riders fighting villains.

Right within the shining light, the darkness is born The huge scale has lost its balance

We see Sora and Izuku standing back to from each other, both looking down

The ones howling and crawling in the dark Destroying the city, ripping it apart

We get a close up of Sora with the images of the Time Jackers and Another riders behind him

Who has the will to become zero The soldiers that have chosen a mission

It then cuts to a close up of Izuku as we see the image of the League of Villains behind him.

Face the fight, never run away, Taking the light...

The images then changed to all of their allies behind them, supporting them.

Forward, Forward, Forward!

The two then looked upward as the scene shined.

Go forth! our hero~~~!

We see the two in their Rider Form and Hero Costume as they leapt towards a large army of monsters and villains.

Pray to the sunrise and swear to the dawn

The two fought back to back as the villains and monsters kept coming.

With the bell of peace...

However suddenly two blasts shot past the, as they looked towards the blasts origins.

Let it ring, hero…

There they saw the class 1A as well as Riku and Luna standing on top of the hill.

It is you guys that taught us

The two smiled at this before they turned back to the large army when the scene flashed.

The true meaning of courage…

We see heroes and rider after the help as they looked towards the sun rise for a new day.

Praise to our hero...

OUR HERO!


Modern-day

Third Person P.O.V.

Tick, tick, tick, tock BEEP! BEEP!

"Huh?" A boy groaned, as he slowly moved around and turned off his alarm clock.

He groaned, and opened his eyes before stretching a bit "So that was the last of the build dreams Huh?".

He then got up and rubbed his own eyes before he yawned "I wonder which rider is next?".

We see him going to the kitchen after changing into his school uniform.

This is Sora Yamato, a 14-year-old ordinary middle school student. He had messy brown hair with violet coloured eyes.

He's a student at Aldera Junior High, his uniform consisted of a white shirt underneath a black buttoned-up jacket and black trousers along with black shoes.

As he did, he noticed that the TV was still on and on the table was a note over a plate of breakfast.

"In later news, several heroes have continued to go missing. The police and hero agencies are still searching to find these missing heroes".

"Geez, how scary," Sora said, as he checked the note next to the breakfast.

"Hey Bro, the agency wanted me to help out with the missing hero case so I had to leave early, sorry. From Misora"

"Huh, hope she'll be okay," he said he grabbed the toast before walking out the door with his bike.

As we see him cycling off, the scene moves up to see someone on his roof.

The person wore a long green trench coat with black trousers and shoes. He also wore a grey hoodie and silver scarf and in his hand was a strange book with the words 'Advent of Oma' on it.

He smirked before removing his hood, revealing his black hair combed to one side and his green eyes before he turned to… us?.

"Greetings, dear readers I am the one known as Woz and welcome to the world of heroes" he bowed.

He then stood back up, before opening his book in his hand "According to this book, this is the world of heroes a world where almost every single person has a power known as a 'Quirk'".

"Some chooses to live their lives normally, some choose to do whatever they wish being branded as villains and some choose to help people and stop these villains being known as Heroes"

"Among these heroes, there is a group that is only known as rumours that have saved the world from the strangest of events as well as the deadliest of monsters, the Kamen riders".

"This is the tale of a boy that dreams of riders, who will rise to rule this world and all others as the greatest demon king known to man," he said, before closing his book.

"But I am getting ahead of myself, I shall be the one to narrate the rise of one Sora Yamato to the realm of legend," he said, looking at the boy currently cycling to school.


Tokyo city

Sora P.O.V.

"Huh, I wonder what happened to Sento and Banjou after the new world was created," I said, walking to school.

Every since I was a kid, I've been having these dreams of people fighting against evil known as Kamen riders.

It's pretty cool having these dreams, it's like watching a show that only I know about but one day I hope I can meet a real one.

"Heh, maybe when I become king I'll finally get my chance" I smiled, looking up before hearing a crash "Huh?".

I turned to the sound of the crash and ran into a huge crowd of people watching a fight between a hero and a villain.

The villain was this big rhino looking guy with dreadlocks that were guarding himself against, a hero in a blue costume with bits of wood in the arms and mask.

"Ah man, don't think I'm getting to school on time now." I groaned, rubbing my head.

"WOW! That villain is huge!" I heard, which made me smile before I looked over at my classmate Izuku Midoriya.

Midoriya had curly green hair and green eyes and was wearing the same school uniform as me.

"Yo Midoriya" I waved, walking up to my classmate with my bike as he turned to me.

"Oh hey Yamato-San, good morning" he bowed, making me smile "So who's fighting today," I asked.

"It's that brand new hero, Kamui Woods! He's young, talented, experienced and has a huge surge of popularity!" Izuku squealed, making me nod "Ooh, wonder if he's strong"

"You! used your skills for illegal purposes, halting up the work travel networks and committing theft that resulted in injury!" Kamui said pointing at the villain. "You truly are the incarnation of evil!"

"Dramatic much?" The villain scoffed.

"AH! Here it is!" Izuku said excitedly. "Absolute Pre-emptive Confinement…."

"Lacquered Chains Prison!" Kamui shouted and fired branches from his arms, he was about to finish this villain when suddenly.

"CANYON CANNON!" A gigantic female hero yelled, kicking the villain off the train bridge, causing him to hit a building and passing out.

"Hi there, I'm Mount Lady. I just started today so I'm glad to have made your acquaintance." Mount Lady winked as a lot of photographers started taking photo's of her while mummering 'Money shot'.

"Huh, she's pretty" I smiled, looking up at her "Alright Midoriya, let's huh?".

"Gigantification huh? She looks like she'll be popular, and it's an amazing Quirk, but thinking about the damage to the city that'll go hand in hand with that, its use might be limited? No, but whether or not she can control the size" Izuku murmured, as he wrote down the note in his future career book.

"Ah Geez, why does he have to do this so much, but all his knowledge on heroes is what makes him great," Sora said, shaking Izuku "Come on Midoriya, we gotta get to school".

"Huh? OH, YOU'RE RIGHT" Midoriya said, running in ahead.

Sora was about to follow him on his bike when he noticed something on his bike.

It looked like a stopwatch, except its face was missing revealing the gears.

"Huh, did someone accidentally drop this?" Sora said, placing the watch on a bench before getting back on his bike and cycling to school.


Classroom

Third-person P.O.V.

"Alright, you're all in your last year in our school now! In other words, it is now or never that you pick your future!" The homeroom teacher said as we see Sora, Izuku and a few other students sitting down in their seats.

"I would hand out these forms for your plans, but you're all…." He grabbed the forms and threw them in the air. "….pretty much going into the Hero Course right?!"

"YEAH!" All the students except four of them cheered, showing off their Quirks.

"Yes, yes you all have wonderful Quirks, but you know the rules no Quirks on the school premises." The teacher scolded.

"Oi, teach!" A bashful voice snarled.

This voice belonged to Katsuki Bakugo, a teen with bright blonde hair and red eyes, who wore the junior high uniform."Don't lump us all in the same group. I'm not gonna be stuck at the bottom with the rest of these rejects!"

"That was uncalled for Bakugo!" Most of the students shouted, anger.

"YOU ALL SHOULD SHUT UP LIKE THE EXTRAS YOU ARE!" Bakugo shouted back.

"Yeah, who'd want heroes with your lame quirks anyway," Another voice said, as we turn to the source of the voice.

This voice belongs to Yozora Fujiwara, who had black clean hair with green eyes who also wore the school uniform.

"If you idiots wanna be heroes so bad, then get quirks that are a bit more… impressive" he smirked, much to everyone's annoyance.

"Oh if I remember correctly, you two want to get into U.A, right?" The homeroom teacher said making Bakugo jumped upon his table and posed quite menacingly.

"I'm not surprised that secondary characters like you are quaking! I got As in all my exams! I'm the only one who can get into U.A! I will surpass All Might and be number one! My name will be inscribed into the highest-earning heroes ever!" Bakugo's screamed as Riku smirked as well.

"Now that I think about it, Izuku wanted to get into U.A as well if I'm not wrong."

Bakugo froze in place and slowly turned to Izuku who tried to hide under his hands.

"Woah, is that true Izuku" Sora asked, impressed as Izuku slowly nodded.

"Y-Yeah, I-I thought that maybe if I tried hard enough… I could maybe… become a hero… too?" He mumbled, but everyone in the class just burst into laughter.

This caused Izuku to cover his face with his hands in embarrassment, but he didn't notice was that Bakugo was fuming with anger whilst glaring at him.

A few hours later, after class

We see Sora finishing up putting his book away, and he was about to leave but then the teacher walked up to him.

"Hey Yamato, mind if I ask you something about your career choice?" The homeroom teacher, as Sora looked over at him "Yeah?".

"Why did you write down king on your career sheet? That's not seriously what you want to do" The teacher asked, but Sora nodded.

"Yeah, that's just the only thing I could see myself doing, I've wanted to be a king since I was a kid," Sora said, but the teacher handed him another sheet.

"Stop kidding around and consider what you're going to be doing," The teacher said, as Sora nodded but there was a frown on his face.

'But I'm not kidding' he thought, before hearing the sound of a small explosion "Huh?".

He looked into his classroom only to see Bakugo's holding onto Izuku's hero book, except it was burnt to a crisp.

"W-Why did you do that, Kacchan" Izuku cried, as Bakugo frowned at him.

"The best heroes out there, well they showed signs of greatness even as students and I'm going to be the only person from this crappy public school to go to U.A. and become a hero, so what makes you think a quirkless runt like you can become a hero," Bakugo said, tossing Midoriyas book out the window as Midoriya looked up.

"B-But there's been plenty of amazing heroes without power, like the Kamen riders" Midoriya gulped, making Bakugo glare at him "You're no Kamen rider".

Midoriya looked down, a bit not noticing that his chest was slightly glowing.

"But hey maybe in your next life you'll get a decent quirk" Bakugo smiled, and placed his hand on the student's shoulder "So why don't you try taking a swan dive and see what you get," Bakugo said, but then Sora came in a smacked his hand away.

"Stop it Bakugo, you have no right in saying who can or can't be a hero," Sora said, glaring at the blonde.

"You're one to say that, Yamato" They heard, looking over at Yozora walking up to them.

"You're the one always shouting about how you will become king, you're even crazier than Izuku," he said, as Sora gripped his hand.

"I know it's a long shot, but you have no right in choosing what we can do or not do," Sora said, as Izuku looked at him.

"Midoriya has shown way more heroic traits than you two have combined, so what makes you two think you can become heroes after the way you have acted, you're more likely to become villains than heroes," Sora said, but then an energy blade stabbed the wall next to him.

"Don't ever compare me to a villain" Yozora glared, but Sora was afraid of him.

Riku scoffed, before dispersing his energy blade before walking off with Bakugo following him.

"Oh god," Sora sighed, as he fell to the ground breathing heavily, "I thought I was done for".

"T-Thanks Yamato-san" Izuku thanked, before leaving the room making Sora smile "No problem".


City

Third-person P.O.V.

In the city, we see the people doing their business or heroes patrolling the streets however what they didn't notice was that a portal was opening up in the sky.

From this portal, a large red mechanical ship flew out that was about the size of a truck.

The ship flew around a bit before it landed on the roof of a building, folding out into a large red robot with a watch as its head.

The ships then looked up at the clear blue sky "W-We did it! The plan worked I've successfully travelled to the past"

The robot then grabbed its hand before nodding "Now, I've gotta find and kill Yamato Sora before it's too late" it said, changing into its ship mode before flying away, not noticing another ship coming out of the portal following and following the red robot.


Hisashi household

Sora P.O.V.

After finishing up the rest of school I decided to cycle back home so I could get change before going out for a bit "I'm home" I called, as I walked into my house only to be met with my older sister resting on the couch.

"Oh hey bro, welcome back" she smiled, before flopping back down on the couch "How was school today".

This was Misora Hisashi, she's 22-year-old sister and works as a hero, is known by her hero name Flash sonic. She had long blue hair with green eyes and was currently wearing a red tracksuit with a yellow lining.

You may be wondering why we have different names, well after my parents died when I was young I was taken in by the Hisashi family, and I'm even considered a part of their family.

"Boring as usual," I said, pouring myself a glass of ice tea "How was that hero job?".

"Bah! It was horrible I had to run all around the city but I still couldn't find those missing heroes!" She groaned "And on my day off too".

I nodded while placing my bag on the table but this made Misora notice the career plan in my bag.

"Ooh, ~ what's this?" Misora asked, quickly yanking the sheet from my bag much to my surprise "H-Hey!".

"A king seriously, you're still going on about that?" Misora asked, making me nod "Well yeah, it's something I've wanted since I was a kid".

"Yeah, but still being a king is so far fetched you should become a hero like me," she said, striking superhero poses.

"Well yeah, being a hero is great and all but besides Japan, super villains rate shave been rising higher and higher," I said, "I just think that maybe if I was the king, I could set an example and make a world where people don't have to be afraid to go outside".

"Well yeah, but you can do that too if you were a symbol of peace like All Might," Misora said, as I smiled.

"Yeah, but you have to admit being a king is way cooler than being a hero" I smiled, making her frown.

She then put up a fake smile before nodding "Yeah, I guess you're right".

There was an awkward silence between us for a few moments after that "W-Well I'm gonna get changed then bo out and buy stuff for dinner".

"R-Right," she said, as I walked off.

As I did, Misora sighed before pulling out a U.A. Pamphlet "Now what am I meant to do with this…".


Streets

Third-person P.O.V.

We see Sora cycling through the streets of Tokyo, minding his own business as he made his way to the supermarket which had a special sale on.

He was currently wearing a blue shirt with beige trousers shorts and black shoes.

"I wonder what I should make for dinner," he said, as he made it to a staircase.

As he walked up the staircase with his bike next to him, he was about to pass by a hooded figure who moved in front of him.

"Congratulations, Yamato Sora," The man said, removing his hood revealing it to be Woz.

"Wha? Who are you? And how do you know my name" Sora asked, as Woz smirked before opening his book.

"You may call me Woz, Overlord" he bowed, much to Sora's confusion "Over-what?".

Before Sora could get his questions Woz stood back up opened his book "According to this book, today will be a very special day for you, one you have been waiting for since you were only a child but remember to beware the red robot".

"Beware the red robot?" Sora repeated, confused when he heard the sound of beeping from the cars.

He turned his head to the cars, before turning to see that Woz was gone.

"What a weird guy, must be a prank or something," he said, cycling away not noticing the red robot hiding behind the wall.

The person inside the robot then proceeded to scan Sora confirming his identity "That's him! That's Yamato Sora!".

Sora finished walking up the steps and got back on his bike, about to cycle down the downward road when he heard the sound of something behind him.

"Huh? EEEEEHHHHHH!" Sora screamed as a giant red robot was running towards him.

"I GOT YOU NOW! OMA ZI-O!" The pilot yelled, as Sora quickly began cycling down the road.

"Woah!" Sora yelled as he moved out of the way of the robot trying to grab him.

The robot then changed into its ship form, before proceeding to chase after the poor boy.

"What the heck is going on!" Sora yelled, as he cycled faster and faster but the robot was easily able to catch up "Is it a villain! But why is he chasing me!" He yelled as it fired several Lazers at him.

One Lazer was about to hit him so Sora quickly jumped off the bike as it exploded behind him.

The boy soon recovered so he ran through the alleyway while the robot flew over them, continuing to pursue him.

Sora eventually made his way to a shopping arcade, which he quickly ran inside.

Seeing the people shopping he quickly started to wave his hand frantically "QUICK GET OUT OF HERE! A VILLAINS COMING!".

To confirm his statement the robot landed on the ground, scaring everyone inside as they began running to the other exit.

The robot tried to get into the shopping arcade but unfortunately, it couldn't fit "YES! How do you like that now you can't chase me".

"Don't think that'll stop me, Oma Zi-o!" the robot said, before standing up straight as the hatch on the front opened up and moved downward before someone jumped out.

This was a teenager, about Sora's age, with black spiky hair and red eyes. He wore a black long-sleeved shirt with red lining, he also wore black trousers and boots. On his arms were two gauntlets used to hold watches that looked like the one Sora found earlier and on his waist was a belt that was white and black with two slots in the side and a white middle with a led screen in the middle, the was also a dial at the top.

"W-Who are you?" Sora asked, as the boy stood up and looked at Sora.

"I am Riku Geiz, and I'm the one who will end you're life Yamato Sora," he said, much to Sora's shock.

He then pulled out one of the watches before pointing it at Sora, as he turned the dial and pressed the button on the top.

GEIZ!

He then slotted the watch into the left slot of the belt and slammed the dial on top causing the device to tilt sideways.

As he did a large black screen appeared behind him, which resembled a digital watch.

The now named Riku's arms then shot forwards, before he swung his arms around in a circular motion before his hands rested on either side of his driver.

"Henshin!" Geiz shouted, throwing his arms to the side before rolling his shoulders as the transformation began.

RIDER TIME!

The digital watch behind him flashed with the kanji rider in hiragana before the letter flew past him.

Three digital watch straps surrounded his body as a red arm, our materialised around it.

KAMEN RI~DER!

The straps then disappeared as the kanji slammed onto his face, forming his visor.

GEIZ!

The straps formed a red bodysuit, red boots with black tips, silver anklets, deep red shin guards with black stripes on them, black watch-crown kneecaps, a black watch strap going down his chest and stopped at his waist. His shoulders were protected by a hexagonal-shaped silver chest guard with yellow markings and red protrusions like watch buttons, he had black gloves with yellow padding.

And finally, his mask, mainly black with a white faceplate except for his visor, where the yellow Hiragana lettering stuck itself to, reading the word 'Rider'; and on his wrists were the same silver straps he had before.

"A Kamen Rider!?" Sora gasped, as Geiz ran towards the boy.

He sent a punch towards the boy, forcing him to duck and roll out of the way.

Sora then got up and started running off but Geiz was easily able to catch up to him before knee if him, Knocking him to the side.

He then pulled out a red and black axe weapon which looked like it could change shape, in the middle of it was the Kanji for Axe.

ZIKAN ZAX!

"Die!" Geiz yelled, swinging his axe towards Sora who pulled up one of the items next to him to block the attack.

"Nani?" Geiz said, confused as the axe got stuck in the item.

Sora then pushed Geiz back as Sora started running towards the exit.

Geiz freed his axe before he switched it to its Bow Mode.

YOU! ME!

He then fired several energy arrows at Sora who was barely able to dodge.

As he made it to the exit, a silver version of Riku's ship lowered in front of him.

The chest of the ship then opened up in front of him "Quickly get inside" The pilot said.

"What! Luna what are you doing here" Geiz said, as Sora quickly got inside of the ship as the chest closed behind him.

When he did, he found himself in a silver room with two gear connecting to two leavers to control the ship.

The pilot was a girl the same age as Sora, she had long flowing dark brown hair and wore a white long-sleeved dress with black tights and boots, she was also adorned in a long white cape.

"Who are you?" Sora asked as she turned to him.

"Introductions can wait, we need to get out of this time," she said, confusing Sora.

A screen then appeared in front of the girl much to the boy's surprise with a picture of the current year 2018.

"Activating space-time system!" She said, before selecting a random date as the ship started flying in the sky.

A portal appeared in front of the ship, allowing them to escape successfully.

Riku watched as his target disappeared, as he pulled out the watch in his driver returning to normal.

"Luna, what are you thinking," he said, looking up.


Meanwhile with Midoriya.

We see Midoriya was walking back home taking a new route since the street I normally take was destroyed.

There was a frown on his face and a clear depressive aura around his, as he gripped his burnt notebook.

'This world… is so unfair…' He thought.

Ever since he was a child, Midoriya wanted to be a hero. He used to watch the world's greatest hero, All Might, saving people on the internet over and over again and dreamed to be a hero as well.

But when his mother took him to the doctor to find out his quirks, he discovered that he was of a few people that weren't born with a quirk.

He was sad about this, especially since he couldn't achieve his dream and only wanted someone and anyone to confirm to him he can be a hero.

That was when he decided to not care about what other people say he would keep up his chin up and keep going forward so he can become a true hero.

As Izuku smiled and continued walking, someone made of green slime came out of the drain behind him.

"Lucky me! A medium-sized body to hide in" he said, before enveloping Midoriya.

'A villain!' Midoriya thought as he struggled to break free.

"Hey, you're a real hero you know that? I was scared that hero jerk was going to capture me but now I found you" the villain said, wrapping around Midoriya "So stop struggling, don't worry it'll only hurt for 45 seconds, then it'll all be over".

'My body, I can't breathe' Midoriya thought, struggled trying to pull the villain off 'Someone… help me…' he thought, not noticing that his chest was glowing a red and blue colour but then.

BOOM!

Suddenly from the drain in the ground came a large muscular man with spiky blonde hair "Don't worry young man, for I am here!".

"What! All Might!" The villain yelled as All Might pulled his arm back.

"Texas… SMASH!" He yelled, punching the villain which created a shock wave that pushed the villain off of All Might body.

'All… might..' Midoriya thought as the glow on his chest disappeared before passing out.

A few minutes later

"Hey, kid! Kid? You okay" Midoriya heard, as he felt someone gently patting his cheek quickly.

"Ugh," Midoriya said, slowly opening his eyes only to see his idol, All Might above him "All… Might?".

"Thank goodness!" He yelled, making Midoriya back up "A-All M-Might you're here!".

"Hahaha, sorry about getting you involved with that, this is a new land to me and I still haven't gotten used to this city yet, but thanks to you I was able to capture this villain," he said, showing Midoriya a bottle of soda with the villain trapped inside.

"As thanks, I signed you're notebook as an autograph," he said, as Midoriya stood up.

"OH THANK YOU ALL MIGHT, S-SO MUCH!" He bowed, making All Might laugh.

"Yes yes, now continue your day Young man and don't forget to continue your studies," he said, as All Might was about to leap away.

"W-Wait!" Midoriya said, grabbing onto All Might as he leapt away.

"Whoa kid, don't you think this is a bit much to get your idol's attention," All Might said, trying to shake Midoriya off, not noticing he dropped the bottle on the streets below.

"I-I-I-I-F-F-F-F I-I-I D-D-D-O-O-O I'LL D-D-DIE!".

"Oh right, then I'll drop you off somewhere," All Might said before a bit of blood came out of his mouth 'Shit'.

The two soon landed on the building roof, as Midoriya shakily let go "S-Scary".

"Of all the, hopefully, the people downstairs will help you get down, I've no time thought truly," he said.

"W-Wait, um," Midoriya said, but was cut off,

"I HAVE NO TIME TO WAI-" "Can some without a quirk… become a great hero like you".

All Might went silent, as he turned to the young boy "Quirks are…GAH!".

Suddenly steam startling shooting out of All Might body 'Shit! Not now!'.

"You see ever since I was a kid, I've been picked on because of me being quirkless… so seeing you heroes saving people was always really cool," he said.

"And the way you save people, with that fearless smile makes me want to be an awesome hero like-YYYYYYOOOOOUUUUU?!" Midoriya screamed as he saw that All Might was now replaced with an extremely skinny man with shaggy blonde hair.

"Who! Wha! Huh! A-An Impostor! You're an impostor!" Midoriya yelled as the skinny man looked at him.

"I am All-BLEGH!" He said, spitting a load of blood much to Midoriya's shock "NO WAY! HOW!".

"Y-You know how people hold in their gut while at the pool? It's kinda like that" he said, much to Midoriya's shock.

"You've seen the real me kid, so don't go around telling people on the internet or something," All Might said, before lifting his shirt to reveal an extremely bad wound.

"Five years ago, before that whole Inves invasion thing I was struck by a villain which damaged my respiratory system, had to get a lot of surgery and now, I can't even do my hero work for more than 3 hours a day".

"W-Who was the villain? Toxic Chainsaw?" Midoriya asked, making All Might laugh.

"Hah! You've done you're homework kid, but that guy couldn't even touch me" he said, before looking down.

"I asked not to make this public to keep people hope in the symbol of peace, that's why I smile to shake off the overwhelming fear I feel".

"So can you become a hero without power, no I should think not," he said, said standing up "If you still wanna save people then become a police officer or something, those villain custody officers are often mocked but it's still a respectable position".

"It's not wrong to dream, but be more realistic," he said, taking the stairs to leave the building.

Midoriya's was silent, his whole body was shaking as he gripped his chest, taking all the information in.

'I-I can't become a hero… even All Might doesn't think I can without a work… t-then I-if I can't without a quirk… then!' he thought, his chest glowing brighter and brighter before purple energy enveloped his body.

BUILD!

The energy dissipated, revealing it transformed Midoriya into a monstrous version of Kamen rider build which now had a mouth and several spikes, looking more organic and on his chest was the words 'Build' and the date '2017'.

"Quirks…" he said, as the spring on his leg moved down before he leapt great leaps

As the monster build leapt through the city a young boy in blue clothes smiled whilst watching him.

Third-person P.O.V.

In the wasteland, we see a large statue of Sora with all of the top heroes including All Might and Endeavor standing around him, and on the bottom of the statue said 'To commemorate the advent of our king, Oma Zi-o'.

In front of the statue, we see an old man about 65 years old. He had grey hair and familiar purple eyes. He wore a long-sleeved black white with golden lining and white trousers. He also had a golden belt with a display screen that had golden wing extensions on the side much like the one Riku wore.

He looked up at the large statue with a smirk "Spectacular… is it not…" he said, before looking out to the distance.

Doing this he saw a gigantic army of people with quirks, weapons and even some riding giant robots.

"Try if you want, but it is pointless," he said, as the large army came running towards the man as he pressed the two buttons in his belt.

This caused the ground beneath to glow as he smirked "Henshin…".

Shukufuku no Toki! Saikō! Saizen! Saidai! Saikyō ō! Ohma Zi-O!

The ground beneath all came to his body and swirled around him as his body glowed before it all burst off.

He was now clad in a black suit he had elegant gold wing styled shoulder pads, gold lining and padding on his arms and legs, a giant golden rolled-styled watch band wrapped around his chest like a sash and coming from his back were two giant white clock hand's styled like a cape.

He wore a helmet that looked like a giant gold watch with a black face, the word 'rider' was written in red across his face in katakana in the rough shape of an eagle. On his forehead were golden watch hands set to the '10' and '2' position. And on his forehead was a silver katakana symbol for 'Kamen'.

This was Oma Zi-O, the demon king of time and space.

Some fired their weapons towards Oma Zi-O however the bullets stopped in front of him before being fired back at them.

Several people used their quirks to try and attack him, however, a barrier around him protected him.

A magic seal then appeared next to him, as he passed his arm through it making his arm grow gigantic before he swatted the people away.

Several of the robots tried to attack him, but he just waved his hand.

This caused several energy bats to come flying out and started attacking the robots and the people.

"You should've realised a long time ago… that you could never defeat me, and you want to know why?" he said, raising his hand.

"… I was born to be the king," he said, snapping his fingers.

This caused a gigantic shock wave to shoot out which turned every person in the area to dust.

"hehehehehe….HAHAHAHAHAHAHAHA!" He laughed, which echoed through the entire wasteland.

The scene froze before reversing back to a close up on Oma Zi-o's face before he transformed before the scene moved back to show that it was Luna showing Sora a video.

"This is you in the future, in fifty's years you will become the worst demon king in history, Oma Zi-O," she said, shocking Sora.

"T-That's me," he said, stepping back before gulping "I-I need some air," he said, before stepping out.

Sora now found himself in some sort of forest with plantlife he had never seen before.

"What the heck is going on today? First, a robot was trying to kill me, then turns out it was being ridden by a Kamen rider and now I've been taken to the who knows where and find out that I'm gonna be some demon king, what's next!".

As if to answer his question, a bit of saliva landed on his shirt making the boy turn around to be met with a Tyrannosaurus Rex.

"W-W-W-What!" He screamed, as the Dinosaur roared and tried to hit him.

Sora closed his eyes, preparing for the end but then Luna came in and protected him.

"Are you okay?" She asked as Sora gulped "Um Luna was it? Where did you take us".

"We're in the Cretaceous period, I thought we'd be safe here," she said.

"WHAT MADE YOU THINK THAT!" He yelled as the robot pushed the dinosaur back before picking up Sora, putting him back in its chest before turning into its shift mode and travelling to another time.


1671

Sora P.O.V.

We were now in the Edo period in Japan, it was kind of cool to be in an old Japanese village. Even if everyone was staring at us weirdly.

"So could you please explain to me what's going on like who was that Riku guy chasing after me and why did you say I was going to become a demon king?" I asked as we walked through the village.

"Okay, as you know, my name is Luna Tsukuyomi. My partner Riku Geiz came from the future of 2068 to kill you" she explained, as I nodded.

"The reason he did this was because in the future you become the demon king Oma Zi-o. A monster that has destroyed almost the entire world, there's only a few people and heroes left that can still fight him but as you saw it isn't going well" she said, looking down.

"Well… then why did you save me? If you want to save your future so badly" I asked, as she frowned.

"Because… I just didn't feel right to kill you when you haven't done anything wrong, and I thought maybe we could change your mind on becoming the demon king," she said, making me smile.

"But I wonder how I would even get that power? my quirk can't do anything like that" I wondered, as she pointed to my hand "Well with that watch in your hand you can".

"What watch in my ha-Woah!" I jumped, when I saw the watch I found earlier in my hand's "I thought I threw this away?".

Luna then grabbed my hand with the watch in it "This is called a ride watch, it's a device that allows someone to copy the memories and quirk of someone else and use those powers, it's how we've survived so far but it's also how you're future self has gotten so much power".

"Please, if you truly wish to help people then destroy this thing and forget you're dream of becoming a king," she said, making me look down.

"I-I…" I stammered, trying to make my decision when suddenly.

"I FOUND YOU!" We heard, turning around to see Riku in his rider form walking towards us scaring all of the villagers.

"Get behind me," Luna said, as she pulled out a gun that looked like it could also turn into a phone.

She fired several blasts at the rider who used his quirk to create an energy barrier to black the blasts before he broke it which created a shock wave that knocked us back.

"Come! Time Mazine!" She said as the robot picked us up before flying through another portal.

"Oh no, you don't!" Geiz said, summoning his robot before chasing after us.

We were racing through the tunnels of time, Geiz blasting us while Luna tried to get us to another period.

Geiz then got closed to us, before he rammed his ship into ours which was able to knock me out of the ship.

"Sora!" Luna yelled as I fell to another period.

"Aaaaahhhh!" I screamed, before crabbing onto the grassy floor before rolling down.

"Jeez, that hurt" I groaned, laying on the grass.

"Oi! You okay!" I heard, as two people ran up to check on me.

"Yeah, I'm alright just a little bit dizzy" I groaned, opening my eyes to see people I didn't expect.

"Ah Geez you scared us there, falling out of nowhere like that," The first person said, who had messy brown hair and navy eyes. He wore a white shirt with red arms and blue trousers with a red checkered shirt and a black and white jacket wrapped around his waist.

"Could it be some kind of teleportation quirk? Ahh! How fascinating" The other person said, as he rubbed his clean black hair, he also had red and blue eyes. He wore a navy shirt with a yellow scarf and blue trousers "Also that voice..l I feel like I've heard it from somewhere".

"Kiryu…Sento…Banjou…Ryuga…?" I asked, making their eyes widen.

"EEEHHH?!"


Warehouse

Sora P.O.V.

"Woah," I said, looking around the warehouse that Sento and Ryuga have been living in for the past few months "I never would've thought I'd get to see this stuff".

"So you're saying you're from the future?" Ryuga asked as he poured some hot water in a bowl of cup ramen "Sound's pretty far fetched to me".

"Well, it's the truth," Sora said, sitting down next to him "Though it's not that impressive, I'm only from a few months in the future, though kinda surprised you guys are back in the year 2017".

"We were surprised too, but hey thanks to us knowing the winning race tickets we were able to get enough money to buy this place," Ryuga said, as he finished pouring.

"Fascinating" Sento said as he inspected the ride watch "This 'Ridewatch' as you call it has technology I've never seen".

He then spun around and lifted the screwdriver "Mind if I take it apart?" He asked, a bit of his springing up.

"Nah," I said, taking the watch off him making his hair go down "It's apparently meant to give me this great power soon, but I still don't know how yet".

"Speaking of which," Sento said, looking at me "How did you know our names? Even if you're from the future doesn't mean you should know how our names".

"Ah, that's my quirk," I said, surprising them "Really?".

"Yeah, pretty much ever since I was a kid I've been having dreams of you guys and other riders adventures and fights so I pretty much know every rider," I said, as Sento nodded "Fascinating".

"Really? Sounds pretty creepy to me" Ryuga said, about to pick up his ramen to eat it when suddenly the door slammed open causing him to drop the ramen all over himself.

"OW! HOT! HOT!" He screamed, jumping a bit as I looked over to see who opened the door.

"Luna! You're here" I said, but then she fired her gun at Ryuga and Sento knocking which knocked them out.

"What did you do!" I yelled as she frowns.

"I'm sorry… but I can't risk the future changing because of this," she said, firing another laser at me knocking me out.

Third-person P.O.V.

We see Luna picking up Sora's unconscious body with the robot, while Sento and Ryuga layed unconscious on the bed.

But what she didn't notice was that most of the full bottles and the power-up items they use to transform look to be glitching out before they dissolved into energy before disappearing.


2018

Yamato Household

Sora P.O.V.

"Ugh, huh?" I blinked, slowly getting up from my bed before looking around "Was it all a dream?".

I looked around my body and couldn't find the ride watch anywhere "I…guess it was…"

I frowned at that, thinking about everything that happened in that dream "I… should go and get stuff for dinner" I said, getting up.

After a few minutes of getting ready, I was off in the streets again just thinking about what those two from my dream said to me.

"Please, if you truly wish to help people then destroy this thing and forget you're dream of becoming a king"

"I am Riku Geiz, and I'm the one who will end you're life! Yamato Sora!"

"I wonder… should I give up on my dream to become king… if it can cause such chaos and terror" I wondered, as I walked when suddenly I saw two heroes be knocked to the ground.

One looked to be a humanoid dog while the other looked to be hero-themed about jumping.

"Hey! Are you okay" I asked, running up to the two heroes but then they resolved into some kind of gas before being sucked away "What in the?!".

"Jumper, doggy? Not best match" I heard, looking over to see a monstrous version of Kamen rider build.

"What the? Build? No that can't be right" I said, which caught its attention as it turned to me.

"More quirks? Yay!" It cheered, as it ran toward me so I quickly covered myself with my hand but then a pulse knocked the monster back.

"Huh?" I said as I checked my hands to see that the ride watch was in my hands again "The ride watch… so it wasn't a dream".

"Now is the time to use the ride watch, my lord" I heard, before jumping. Quickly looking over to see that it was that Woz guy from earlier.

"You…" I mumbled as he turned to me "I apologize for surprising you my overlord, but never mind that now is the time for your advent, use the watch to transform and defeat Another Build"

"…I…" "DON'T!".

We looked over and saw Luna coming in while firing at the now named Another Build "If you use that watch then you'll be on the path to becoming Oma Zi-O!".

"B-But I…" I said, closing my eyes and gripping the ride watch not sure what to do.

'What do I do! I don't want to become Oma Zi-O but I still want to become king and stop that monster! What do I-'.

Suddenly all the dreams I have had about the Kamen Rider's flashed before my eyes all at once before I went silent… I knew what to do.

"I'll do it… I'll become Zi-O," I said, as Woz smiled.

"Excellent choice, my overall-" "BUT!".

"I won't become the demon king of time that you know, I'll do everything in my power… to change my path and become the greatest and most beloved king of all time!" I declared, as the ride watch shined and turned into a white and black colour.

"What…" Woz said, his eyes widening as I inspected the ride watch.

I turned the dial on its face to make it look like a head before pressing the button on top.

ZI-O!

"My lord, take this belt, you should already know how to use it," he said, holding up the belt on a red velvet cushion.

I slowly lifted it, before placing it on my waist which caused a belt to wrap around my waist securing it.

Remembering how Riku did it, I slowly inserted the ride watch into the belt's left slot before pressing the button top, causing the belt to tilt.

This caused a large mechanical watch to appear behind him with its hand moving around.

I raised my arms to the left before I moved them over my head as they eventually landed into position. My left hand held raised to my upper right side, palm outwards, while my right hand faced open palm up at my hip.

"HENSHIN!" I yelled as I backhanded the belt causing it to spin in 360 degrees before I crossed my arms and moved them to my sides.

RIDER TIME!

The hands-on holographic clock slammed together at the twelfth position, before they split to the sides, the small hand landing at 10, while the big hand settled at 2. Three pink Japanese characters formed under the hands on the clock, forming the Kanji for 'Rider' in Katakana.

KAMEN RAI~~~~DA~!

As this was happening three bands that resembled watch straps circled, forming the armour around me, as the kanji flew past me before slamming on my face, becoming my visor

ZI-O!

The black bodysuit had dark grey boots with silver anklets, pink markings on shin guards that protected my legs, silver watch-crown-styled kneecaps, on my hips were two more pink stripes, from the chest to my waist was a single silver link watch-strap, over my shoulders and chest was a watch's edge styled shoulder-guard. My hands were wrapped in black gloves with pink markings, four wrist holders that held four blank black watches similar to my own.

And finally, my mask was a watch's face, the visor having the pink katakana for the word 'Rider' on it.

"I-I did it! I-I transformed" I gawked while looking at myself.

"N-No…" Tsukuyomi sighed, looking down.

"IWAE!" Woz yelled, much to my surprise "The one to inherit all Heroes powers, the time king who will rule over the past and the future! Truly, this is the moment Kamen Rider Zi-O is born, and you all have just bare witness to his advent!".

"Now my lord, fight to your heart's content" he bowed, moving away.

"It's time…" I said, as I slowly reached for the dial on the side of my helmet "…TO RIDE!" I yelled, twisting the dial as it lit up.
