-Lincon city-America- Morning - Rainy

Lincon city, far beyond a normal city. The proud city of Lincon had been through a lot over the years but recently had been destroyed due to a villain named Blackout the city was almost sounds of bullets firing were heard from below the city. As explosions were set off. At Kiwami where the resident homes were blown up and attacked by a strange force. However, the LCPD cannot suppress one particular enemy as they were killed by some sort of white needle to the chest that pierced them to bleed out. However, more LCPD reinforcements attacked the mysterious walking monster with needles like a hedgehog as the bullets were no use.

Radio free rider: "This is JokersKat and were coming live at Kiwami Lincon City, the LCPD are currently repelling these monsters known as the Smash who are the real threat to the humanity. They are currently doing their best until The heroes arrive-"

The Smash used it's needles to kill someone. Zooming out to a mysterious room where a long orange haired woman was seen wearing a black aviators jacket and fingerless gloves with a steampunk themed attire as she sighed.

"I guess I'll be going out then…" The young woman stood up from her chair as she looked next to the table, revealing to be some of device for the belt and two bottles objects that are red and blue as she takes them. "Hey, I'll be going to stop the Smash now."

On the first floor where the person wore the device like a belt and looked at the person named Raven Starr who was seen on his computer desk behind the lab equipments as she was watching the footage from the drone. But, she was wearing a black hoodie to keep her disguised away from the public.

"All right, be careful out there. The heroes might be coming soon because of that news. One of the Riders might intervene to destroy it." Raven told her as she sighed.

"I get it. All I need is to get a job done, right? Besides, You're being hunted down for being Accel" person told her as she calmly facepalms.

"No need to tell me twice, Becky, My job is to help you to find these Smash and defeat them. Please, good luck." Raven called her name as Becky cracked her neck.

"Yeah, yeah… I guess I'll have to thank the dead later on…" Becky said to herself as she waved goodbye as she left out of her lab , heading away from the building called the dexter building. Then at outside, she looks at the Kawasaki Ninja ZX-14R with a red/blue color palette as she got on and wore her helmet. "Let's do this…"

Meanwhile, the havoc continues as the monster shoots more needles as it hits the LCPD officers

LCPD officer 1: "Our guns isn't working. Not even a tank can't even land a scratch! Retreat! I repeat, retreat!"

LCPD officer 2 : "It's no use. Fall back!"

Then, all of the LCPD got into their cars and fell back while the others are on foot. The monster didn't care as it decided to continue walking towards until…

"Hey, you're that NeedleSmash, right?" Becky called at the monster as it turned behind to look at her on his motorcycle as she parked it and puts her helmet away while it was raining. "Sorry to say this, but I'm going to be your opponent today so play with me, alright?"

Becky had her device worn on her waist like a belt already as she grabs out the two bottles objects from each hand as she starts to shake them for a few seconds and twists the cap as she starts to place the red bottle to the first slot and the blue one to the second.

[RABBIT! TANK!]

[BEST MATCH!]

"Just to let you know, I'm not going easy on you." Becky said as she cranks the lever on her right side three times. "This Build Driver better function well."

Then, a melody beat of a construction theme plays as she glared at the NeedleSmash in a serious look.

[ARE YOU READY!?]

"Henshin…" Becky said one word as the NeedleSmash attacks first by shooting a barrage of needles to the ground, causing it to explode… But the theme plays as well.

[HAGANE NO MOONSAULT! RABBIT! TANK! YAY!~]

Then, the smokes of explosion disappears as it reveals to be a person in a strange suit with a black, blue/red color scheme. But the helmet has a blue tank on the left and the red rabbit on the right. However, she cracked her knuckles in preparations.

[ Excite by diachi miura ]

"Kamen Rider… Build… Let's make this showy." Becky introduced herself as Kamen Rider Build as she runs towards the NeedleSmash as it retaliates back at shooting more barrage of needles. However, Build left red leg with a white spring on it charges for a huge jump, causing Build to jump off the wall building and dives towards the Smash with a punch. "Too slow. Come at me!"

The NeedleSmash decided to attack with a punch until she dodged and performed a uppercut and kicked him away. Build continued to walk towards the Smash as it tried to land a hit but she punched him back to pressure it.

"C'mon, aren't you going to hit me back? Geez, you pretty much suck." Just as Build was about to perform a roundhouse kick. The NeedleSmash turned around and shoots out a burst of needles and knocks her away as she felt a little bit of pain. "Heh… Now you've asked for it."

Build runs towards the Smash as both continued to trade in hits numerous times but Build drags the Smash to the children's park area as she threw it to a jungle bars as the NeedleSmash crashed and covered by smoke. Then, the surprise attack of needles came out from the smoke causes Build to take damage by it as she was launched into the air as she backflips and lands.

"You're not bad, creating a sneak attack on me. But, you do seem to have one flaw. Why? Allow me to explain." Build continued. "Your attacks are barely weak, along with your needles. I was thinking… are these needles poisonous? Maybe not, you're hardly trying your best to damage me as much as possible. So what are you waiting for, don't bore me and fight."

"Becky What's your current status?" Raven asked her through her comms as she was busy fighting.

"Pretty good and doing okay. This Smash is hardly putting up a show for me and I'm getting bored soon." Build replied to her as she held NeedleSmash's left arm. "Besides, I have the upper hand."

"Great. Finish it off quickly before The riders arrive." Raven told her as she sighs.

"I was planing to do so but sure." Build simply replied as she kicks away the Smash as she does some quick warm-up stretches. "Sorry, It's been fun. You putted up a decent fight there."

Build proceeds to crank the lever again as the melody plays once again.

[READY, GO! BOLTECH FINISH! YAY!~]

"Raaaaaaaaaaa… HA!" Build jumps high as her red leg glows to charge up as she backflips one time and dives towards the NeedleSmash. "RABBIT KICK!"

Just as it was diving down towards the Smash. It reacted to shoot a barrage of needles towards Build, causing it to collide and explodes to release a huge smoke. But, the rainy clouds were blown away upon this reaction as the blue sky lights on the ground again. Then, Build lands as the smoke clears it, revealing that the NeedleSmash has made it's escape.

"Tch…" Build felt annoyed as she takes off two bottle, causing her suit to dissapears in particles.

"Did you get the Smash?" Raven said to her as she replied.

"Mission failed, he escaped." Becky replied in annoyance as she sighed. "I'll return back to the lab now-"

" Great… I wonder what happened to the riders? This should have gotten their attention." Becky said to herself as she got on her motorcycle with her helmet on and drove off.

-Becky's Lab - the dexter building - Lincon-

Then back at the lab once Becky's home until became a base operation after bringing Raven in after she was being hunted down by Kamen riders. Becky parked her motorcycle and takes off her helmet and comes in.

"I'm here. So, messin' with the lab equipment?" Becky said to Raven as she points it to her… A woman with wavy long pink hair that touches her waist and has a ahoge who was seen using his equipment. But, she was wearing a white lab coat but has a black dress under it and black knee socks and black knee shoes. However, she was a bit tanned but not that tanned.

"Hey, you there. Who are you anyways and why are you here?" Becky said to her as she turns around. She has green eyes and wore small golden earrings and oval wireframe glasses.

"Ahh! Forgive me for using your lab equipment. I hear this is used to make Full Bottles so I have experience on it." The 32-year old pretty-looking woman with breast size of b cup said to her but noticed Becky wearing the Build Driver. "Hmm? Is that a Build Driver you're wearing?"

"Umm… Yes? Who are you, by the way?" Becky asked her as she forgot.

"Ahh! Please forgive me. I am Katiplier, I'm kamen rider Ex-aid… As well as a genius gamer from another dimension." Katiplier introduced herself as she continued. "You must be Becky Lynch, Raven told me about you. Hows using the driver?"

"It's… going fine. You said your a rider right?" Becky asked her.

"Yes i was brought here by Ryu Sengoku " Katiplier mentioned one name as Becky remembers meeting Ryu Sengoku few years ago.

"Sengoku?" Becky said the name as Kariplier noticed.

"Hmm? You know him? Last time I remember, he went missing for no reason. Do you know where he is?" Katiplier asked her as she looks down but has to bring that up.

"He… He died… He gave me the Driver and the Full Bottles after i found his lab they were in it " Becky replied to her as Katiplier was shocked about that. But, she kept her composure and calmed down.

"I see… at least… he'll rest in peace now. I'll just have to find another way home one day " Katilplier continued as she pats Becky's shoulders. "But, from now on. I shall settle into the apartment next to you with my friend Jessikah strange. You still need help after all."

"Umm… sure? That's cool. But, What can you do?" Becky asked her as she happily smiles with a sexy tone.

"Gladly. You see, I can make Full Bottles for your Driver. To do so, I need the materials of the Smash so I can 'purify' them. Even relic materials." Katiplier explained of her profession as she thinks…

"Purify?" Becky asked her.

"As in, convert them into compatible Full Bottles. Though, since this is your lab equipment. This shall be mine from now on so I'll do my best to help you.~" Katiplier replied to Becky sighs.

"Sure, just don't do anything weird." Becky told her as she salutes.

"You got it!~" Katiplier continued. "Speaking of which… I could make one Full Bottle set right now if you want?"

"Wait what?".

"Sure thing! Though, I can purify it and that'll depend how long will I finish it. There's a small chance that I might finish it quickly with perfection but I have to do this right." Katiplier continued. "Time for me to do some work.~"

Katiplier becomes more confident as she starts doing her own work on a sample of her driver and gashat into a Full Bottle.

*CLING! SWASH!*

"Tch… it looks harder than I thought…" The blue haired girl with a side-ponytail on the left side of her head that is longer than the rest of her hair, which falls to just above her waist and cut straight. But, she had a light blue and black bodysuit with forearmed gauntlets, black headphones, and a blade on each of her ankles. Plus, she was wielding her katana as she was taking a heavy breathing after dealing with the NeedleSmash's attack. "I'll make sure this needs to die fast."

But, the NeedleSmash fired a barrage of needles towards her as she quickly swings her blade to deflect them all.

"Great… what now…" The blue haired girl spat in annoyance until…

"Hey, you're Korai, right?" The voice of Becky spoke as she noticed and turns around to see her taking off her helmet.

"H-Huh? How did you know my name?" The blue haired girl named Korai asked her as she approached and passed through her.

"A friend told me to… watch over you. Again, you look pretty beat. That's one flaw for you." Then, Becky had her Build Driver ready as she grabs out two main Full Bottles as she shakes them and twists the cap. "Allow me to show you of how a real professional can pull it off."

And then, she inserts to at them one at a time.

[RABBIT! TANK!]

[BEST MATCH!]

"And sup, NeedleSmash. Miss me? Because I'm about to open a can of whoop ass." Becky spins the crank three times as the beat plays as she stood where as she yawns. "I feel sleepy but I gotta do this quick."

[ARE YOU READY!?]

"Henshin!" Becky said one word as the driver plays a theme for the main form as the burst of energy circles around her. The wind spun around her and burst off as her body formed into a suit from the same on before…

[HAGANE NO MOONSAULT! RABBIT! TANK! YAY!~]

[Go go power rangers instrumental]

"Yay…?" korai was confused one bit but looked at Becky now because of her suit.

"Kamen Rider Build. Let's make this showy, Spiky." Build then rushed into attack with a kick as NeedleSmash fell down but got up as it fired a needle from it's head as she dodged. "Nice shot. Shoot better next time."

"Her fighting skills… She's dealing this monster easily but I tire myself in exhaustion… How is this possible?" Korai got up as she approached to Build who is still fighting the Smash as she drop kicks it away as it fell on the ground.

"C'mon… You're even trying? You're getting worse more than before!" Build complained at the Smash as it got up.

"You there! Build… right?" Korai continued. "Allow me to fight alongside you."

"Like I said, I don't need help but I'll let this slide." Build bluntly replied to her as they both go in to assault the Smash.

Build kneeled down as Korai jumps off from her back as she lands a slash from above. Then, Build rush in with a triple punch combo as the last hit knocked the Smash back.

"My turn. HA!" Build then jumps off on Korai's shoulder as she rider kicks the Smash in direct hit just as it fell.

"H-Hey! W-Why did you do that!?" Korai stutters and looks at Build as she shrugs.

"I dunno. Teamwork?" Build jokingly replied about it.

"At least come up with better teamwork next time." Korai only replied as the NeedleSmash got up again and fired a burst of needles and…

"WATCH OUT! GAH!" Build protected Korai as she fell and got up. "Ooooooow! That freakin' hurts! Though… not bad…"

"You okay, Build!?" Korai held her still as she raises her hand a bit.

"I'm good. But… speaking of which…" Becky cracked her back to prepare herself. "Good thing Katiplier made this new ones for me. Alright, time to put it for a good use!"

Becky then shakes the bottles and twists the caps as she switches out the Tank and Rabbit and puts the new bottle in.

[Doctor! Gamer! Best match!]

The melody plays once again as she cranks the lever again three times as the beat plays as Korai watched.

"E-Ehh? H-How?…" Korai wondered of how did she get that.

[ARE YOU READY!?]

"Build UP!" Becky said as the blue color of the Tank switches out and quickly forms into a new kind of power the red color also changes the blue becomes pink and the red becomes white/grey. But, the helmet on the left had a nes controller and the left had a stethoscope Then, on her left shoulder had shoulder what looks like a N.E.S. Controller sticking out on it and had controller cords on the right ankle that looks the same color and look like Korai had.

"W-What the… that almost looks the same as mine!" Korai's eyes widen in shocked to see Becky's new power.

"So this is called Ex-aid form, huh? Don't mind if I do!" Becky smiled under the helmet as she dashed in action as she Rotary SwordGun Drill Crusher in hand as she slashes the NeedleSmash with ease as he starts to overwhelm it by force. "Man, I feel great with this. Now… For the finisher…"

She puts his Drill Crusher away as s he cranks the lever three times again as the melody plays.

[READY, GO! BOLTECH ATTACK! MIGHTY CRITICAL STRIKE!]

"CRITICAL STRIKE?!" Build jumped and spun her right leg as the cords on her right ankle shifted as she kept on spinning like a tornado as she cuth through the NeedleSmash as she lands with a drift. Just as she stood up and didn't even look. The Smash exploded in the process. "Jackpot!"

"Phew… that takes care of it." Build then takes off two Full Bottles as she de-transforms back to her usual self. "Now… the sample that Katiplier needs."

"Hold it!" Korai stops her and looks at her. "How… or when did you get it. Tell me, who are you…"

"Me?" Becky continued. "The names Becky lynch Kamen Rider Build."

Becky grabbed out a vial flask and grabs the needle with a clip inside the flask and closes it with a cap.

"We can't here though. Raven is safe back at my base. Follow me and I'll explain everything." Becky continued. "You have a ride?"

"Y-Yes…" Korai replied.

"Then let's go." Becky heads to her motorcycle and waits for Korai to get on her ride as they both drove off in order for Korai to know everything of what's going on.

-Becky's Lab-

Just as minutes passes of bringing Korai in. Becky has to explain everything because it was a pain to her to do so. So, Becky asked her about her story. Why did she act on her own while the other users are in hiding. Some paired, some went solo.

"You see. We still reside in the same base located at Sentai Academy. However, it's been over run by Something called Jark Matter and we had to stay on the run together until I decided to split up on my own volition. Now, we can't come back. The others like Jessi are still trapped inside the base but I'm my best as I could." Korai explained the reason why since Korai is hunted by Jark Matter after the riders disappeared.

"I see… sucks that they even called you murderers but you aren't." Becky said to her as she nods to agree.

"You're right. Jark Matter falsely accused us like it was nothing. I won't forgive them of that they did." Korai tightened her hand in anger in hopes to get revenge on Shocker group. But, Korai sighed and decided to let it go. Just as that, her armor deactivates.

"Don't worry. For now, I'll give you a room to rest. I feel tired. You as well. Raven will keep doing her work and might sleep soon. While Katiplier has the sample and working on something new. Kariplier. Tell me if you finished purifying it." Becky called her as she gives her a thumbs up.

"Sure thing.~" Katiplier replied as Becky decided to head off to bed.

"Let's go to bed, Korai. Let's hope your friends is going to be okay. For me, I'm just different." Becky yawned as she headed up to stairs and into the living room. However, she decides to sleep on the couch… "Oi… Korai...You can use my bed… Night…"

So, Becky decided to sleep because she didn't care anyways. Korai shrugged of and decided to enter in her room and sleep as well…

"Damn… Katiplier… don't put shaved chocolate in my…" Becky snored as she fell fast asleep and decided to call it a day.

"Bad news… Phoebe Halliwell… is being targeted by Shocker"

Everyone except Becky: WHAT!?"
