Greetings denizens of the internet and welcome to my first ever fanfiction. I have quite a bit of info I'd like to share with you on how I plan to update this story and the future of it but I'll save that until the end of this chapter (well prologue technically). So if anyone happens to enjoy the inner machinations of my mind you should read the info below. But enough stalling I present to you my RWBY x Pokémon crossover 'Trainer to Huntsman' enjoy!

Note:

RWBY is owned by Roosterteeth and Pokémon is owned by Game Freak, please support the official release.

-Night Time, City of Vale-

Loud footsteps echo in the empty streets. Most people at this time of night would be fast asleep or hanging around some club, that's what this man wanted to do anyway. His name was Junior and is the owner and bartender at one of Vales seediest and dirtiest night clubs, and currently was running for his life.

'Oh God, why did I think it was a good idea lending my men to him.' He thought to himself as he ran into an alleyway and found himself facing dead end, forcing him to stop. He panted heavily in place and wiped some of the sweat of his forehead with his sleeve.

Another set of footsteps were heard behind him, Juniors heart skipped a beat and he cautiously turned around. The owner of these footsteps was none other than what many considered Vale's underground crime kingpin; Roman Torchwick.

"Why do you people always run?" Torchwick asked taking a puff of his cigar. "I just wanted to talk to you about some… Compensation after your men couldn't even help me with that job I mentioned."

"Compensation." Junior said annoyed. "You come into my place of work, shoot the ceiling calling out my name, and that's your idea of compen-" Junior stopped talking when Torchwick raised his cane at him.

"Well that's just an occupational hazard in our line of work." Torchwick said as he dropped his cigar and crushed it with his foot. "It's just business."

Torchwicks cane had a sniper lens appear out of it as Torchwick massaged the canes trigger. Junior gulped and raised his arms in front of his face as he prepared for what was about to happen next.

"Excuse me!"

Torchwick and Junior both flinched at the sound of another voice, both looked to see where it was coming from and saw a young boy.

He was in his late teens, but had a round face that made him look a bit younger. His eyes and hair were both brown but his hair was short and brushed neatly to the right. He wore a bright cobalt blue jacket that was grey under his arms and was currently zipped down revealing a plain yellow T-shirt. He also wore blue jeans and a pair of black boots. On his back he was carrying a yellow backpack with black stripes and lots of zipped pockets and finally, he also had a plain grey fedora with a black lining on top of his head.

Torchwick eyed the boy up and sighed.

"Look boy scout." He said in a mocking tone. "Trust me you don't want to get involved and you definitely don't want to stick around and see what happens next."

"Oh, I believe I do." The boy responded. "I can't help it really, ever since I was young I couldn't stand by seeing someone else in trouble. And that man cowering in the corner definitely qualifies."

He gestured towards Junior who looked like he was going to respond but instead just stayed silent in the corner.

"Well you're not wrong. But I don't have time to deal with you, luckily I have people who do." Torchwick snapped his fingers and four figures entered the alleyway: two men and two women. They wore primarily black, had small horns appearing from under their hoods, and alarmingly wore white masks.

"You're working with those White Fang extremists!" Junior exclaimed. "I didn't think you were that insane!"

The four members gritted their teeth and the boy shook his head.

"Look I know this is stressful for you, but please do yourself a favour and shut up. Trust me, I'll get you out of this."

For some reason Junior seemed calmed by his words, either this guy had something up his sleeve or was the biggest idiot this side of Vale. Regardless he was glad he was here.

"All right guys I'll give you all one last chance. Surrender now and we can all pretend this never happened."

The boy placed his backpack on the ground and stood with his arms crossed waiting for an answer. He was met with one of the male White Fang members charging at him with a clenched fist.

"Guess that's my answer then."

The boy pushed the punch to the side and grabbed the members arm, he swivelled himself to the side and used his other hand to grab hold of the members waist. In one swift motion he threw the member over his hip tossing him to the pavement. As the boy turned away the man got back and threw a punch which barely missed the boy. Seeing the failed punch, the boy quickly elbowed the man in the face before swiping his arm to the side striking him across the cheek with a closed fist causing the man to step back. The man readjusted himself as the boy delivered another punch against his jaw making him flinch, before the boy delivered a side thrust kick straight in his gut winding him, making him collapse unable to continue.

The other members saw their comrade get beaten and quickly took out a weapon of some kind. One woman held a dagger, another had a katana and the other male member held a large club. The boys' eyes widened.

"You'll pay for that you human scum!" One of the women said. The three of them started to corner him and Torchwick laughed in the background.

"What's wrong boy scout. Realised your mistake yet?" He taunted.

The boy looked down at his waist and saw six round spheres each roughly the size of a golf ball attached to a brown belt. The top half of the sphere was red and the bottom half was white, each colour separated by a black line in the middle that extended outwards from a white button right in the centre of the front.

'Don't say I didn't warn them.' The boy thought as he grabbed one from his belt, the White Fang members cautiously stopped after seeing the device in the boys' hands. He pressed the centre button and it grew to the size of a baseball. They braced themselves but none of them could have prepared for what was gonna happen next.

"Come on out pal!" The boy shouted.

He tossed the ball into the air and it exploded into a bright white light blinding everyone around him. When they looked back they were astounded. In front of the boy was a mysterious creature.

It was a large, frog-like humanoid. Its body and legs were dark blue, with single large white bubbles on its legs and arms and white spots over its eyes. On the sides of each of its upper thighs is a light blue, four-pointed star, which resembles a shuriken. Its back feet have two toes, while its front feet have three toes and both feet are webbed. It has a yellow chest and a yellow-and-blue face. It has eyes with white sclera, red irises, and white pupils. A large, projecting dark blue stripe runs down the middle of its head, with projecting light blue stripes in between its large, yellow ears. Its mouth is hidden behind a large, pink tongue that wrapped around its neck and extended outward behind its head.

"What the hell is that thing?!"

The creature took reasonable offence to this.

"Let's get introductions out of the way then." The boy said smugly. "This here is my good pal Greninja. And Greninja… You know what to do."

"Greninja." Greninja said with a grin.

The second male member quickly charged at Greninja and brutally swung his club against it, only for the Pokémon to nimbly avoid it by jumping in the air.

"Aerial Ace!" The boy commanded.

Greninja's right foot began to glow light blue and it began falling at great speed leaving a golden trail before delivering a swift kick directly on the members head knocking him out. The member with the dagger went next and attempted to stab Greninja only for Greninja turn around with a blue fist and delivered a swift punch to the abdomen knocking them against the wall. The member was winded but quickly went for another stab, and Greninja quickly grabbed her hand and lifted its leg into the air, delivering a third and final golden slash of aerial ace she collapsed face forward into the ground causing her to drop the knife. Greninja suddenly felt a sharp pain in its back and quickly turned its head to see the final scared member holding a katana. Greninja responded by summoning its own blade made from a dark energy and turned to fight the final member. Meanwhile Junior seeing a chance to escape started to crawl away from his dead end.

'Heh. I love this kid.' Junior thought. 'Maybe with some persuasion I can get him to work for-'

Junior suddenly felt his hand getting crushed and looked up to see Torchwick above him with his foot on his hand and the end of his cane in front of his eyes.

"Not today." Torchwick taunted.

Torchwick started pulled the trigger and suddenly felt himself getting shoved to the ground causing his shot to miss. He landed hard and turned to see the boy on top of him.

"Sorry, but I won't let you kill him!" The boy yelled.

"Get off me!" Torchwick retorted.

Torchwick slammed the boy across the face with his canes handle knocking him away.

"Ugh I am so tired of kids ruining my plans."

He looked to see the boy rubbing where he was struck, he looked at Torchwick with annoyance and Torchwick could see that the area was already beginning to bruise.

"Wait a minute…" Torchwick murmured to himself. "Wait a minute!" He said much more enthusiastically. "You don't have aura, do you?"

The boy just stayed silent. And Torchwick began laughing callously.

"Oh wow. I'll give you credit, you've got the spirit of a huntsman in you and you'll die just like one, but come on boy scout, this was stupid don't you think?"

The boy just stayed silent before looking back at Torchwick with a grin.

"Forgetting someone." He hinted.

It took Torchwick a second to get what he meant but by then it was too late. Greninja appeared standing in front of the defeated White Fang members with a blue swirling energy in its front feet.

"Use Water Shuriken!"

Greninja quickly threw the attack at Torchwick and it transformed into five blue shuriken's made of water. They flew so fast that Torchwick couldn't even react, each shuriken made contact cutting him and driving him back. Torchwick quickly recovered and shot at Greninja, only for him to block the shot with his arms and visually showing very little damage.

"What the-" Torchwick started to say bewildered.

"Use Aerial Ace!"

Greninja jumped quickly at Torchwick and performed a spinning kick launching him against the wall hard before he slumped to the ground. The boy and Greninja looked at each other in victory.

"We did it pal." The boy said patting Greninja on the head.

"Ja." Greninja responded happily.

Torchwick slowly got up and the boy and his creature readied themselves.

"You wouldn't happen to know a girl in red with a scythe, would you?" Torchwick asked in an annoyed tone.

"Can't say that I do." The boy replied. "But I already know I like her."

The boy smirked, Torchwick frowned, Greninja stood with its arm crossed and Junior didn't dare do anything.

"If you turn yourself in now, then I can have Greninja leave the imminent pounding to a minimum."

"Not a chance boy scout! Besides, you're not the only one with close friends."

Suddenly the boy felt a painful blow in the back of the head and got knocked into the wall.

"Greninja!" His companion said panicked.

Greninja got into its fighting stance and saw where the attack came from. What stood in front of Greninja was a young girl with: brown, and pink hair. She also had two different coloured eyes and held an open umbrella.

"Ninja?" Greninja responded.

"Excellent timing as always Neo." Torchwick complemented. "If you wouldn't mind."

Neo nodded and closed her umbrella and projected a thin blade from its tip, she then gestured the young boy and Greninja charged at her in retaliation. Greninja's fists went blue and it started using Aerial Ace. Neo however parried every hit with the golden light not even touching her and made Greninja tumble in front of her, before reopening her umbrella. Greninja regained posture and went at her with its dark blade only for her to shatter when the attack made contact.

"Grenin… Ja?"

Greninja looked around and saw Neo standing next to Torchwick, Torchwick himself giving a salute.

"Greninja."

Greninja put his hands on the blue stars on his legs and got two stars of water, he then put his hands together applying pressure and power before throwing two Water Shuriken's at Neo and Torchwick… Only for them to shatter into millions of pieces when the attack made contact and the two disappeared into the night.

The boy slowly got up clutching the back of his head with his left hand. He scanned the floor before finding his most precious item… His plain grey fedora.

"Phew. Glad I didn't lose you." He said to himself.

He grabbed it and placed it neatly on his head, and removed his left hand. He then looked around and saw that not including himself, only Greninja and a stunned Junior were left standing. The four White Fang members were down for the count.

'Greninja really went to town, but that Torchwick guy must have gotten away. Darn it.' He thought before patting himself down to try and remove any dirt on him.

"Hey Greninja you doing alright?"

There was no response and the boy was about to check on Junior when…

"I… I…"

The boy looked back at Greninja with a raised brow and Greninja looked at him.

"What just happened?!" Greninja yelled into the night.

"Um Greninja." The boy said sheepishly.

"She shattered! They shattered! They shouldn't have shattered." Greninja interrupted.

"Greninja." They boy said again.

"I couldn't stop them… I couldn't protect you… When you got attacked… I… I…" Greninja trailed off into silence before taking a deep breath.

"Gre-"

"I'm fine." Greninja interrupted again in a much calmer tone. "I'm disappointed but I'm fine. Are you okay?"

"We're not alone Greninja." The boy said slightly annoyed.

Greninja acted confused but then saw Junior on his knees.

"That thing can talk!" Junior cried.

Greninja then facepalmed and groaned.

"I am suuuuuuuch an idiot."

The boy just shrugged.

"It happens, just try not to do it again unless I say its okay. Besides we've got other things to do right now."

The boy started walking to Junior and Junior got himself up.

"Look man, thanks for the save. You know if you want a job then maybe I can hire-"

"Who said I'm here to save you?" The boy said with a sinister tone.

"Excuse me?" Junior replied.

"You're Junior right?" The boy continued. "You own a night club: Bear DJ, Twin girls, Black suit and Red tie dress code."

Junior started to get annoyed.

"Yeah, that sounds like my place. What about it?"

"Oh, it's nothing. But there has been some talk about what your men do on the side."

'Oh no.' Junior thought.

"Illegal smuggling, 'protection fees', incidents at rival clubs…and as Torchwick said, occasionally lending your men to do someone else's dirty work."

Junior started walking slowly backwards only to bump into Greninja startling him.

"Going somewhere?" Greninja said in a sarcastic tone.

"You may not be as bad as Torchwick but you're still up there, and as long as you're free then who knows who you'll hurt next. And I won't let that continue." The boy told Junior seriously.

Junior ended up getting on his knees with his hands clasped together.

"Oh brother." Greninja commented.

"Please don't kill me." Junior begged. "I know you're a good guy. You're a huntsman right, keep me alive and I can make it worth your while."

"I'm not a huntsman." The boy complained. "And I'm not going to accept some petit bribe."

"Please I'm begging you! I'll do anything!"

"Anything?" Greninja asked with interest.

"Anything!" Junior confirmed.

The boy placed his chin on his fist and thought for a moment.

'Alright he took the bluff.' He thought. 'Just don't mess this up.'

"Two things!" The boy demanded.

Junior gulped and Greninja signalled with his front foot to 'turn it down a bit'. The boy cleared his throat.

"Firstly, if you focus only on your bar and no longer delve into some of your more…seedier practices. Then I think there's no harm in leaving you around."

"Oh, thank you!" Junior praised. "Thank you, than-"

"And the second!" The boy interrupted. He paused for a second and breathed outwards nervously. "I am aware that you have some spare rooms in your club for when some of your patrons are too…intoxicated to leave safely. Or if they would prefer to stay with one of their…guests." He said as nicely as possible. "And while I'm here I would prefer-

"Take it!" Junior interrupted.

"Excuse me?" The boy said surprised.

"A room right. You want one, it's all yours you won't even have to pay rent."

Greninja and the boy quickly glanced at each other and both gave sighs of relief.

"Yep, that's all." The boy responded.

"Good, good just one small thing." Junior added suspiciously.

Greninja and the boy ceased up.

'Did he call my bluff!' He thought alarmingly.

"If I'm keeping you in my place of business, then I'm gonna need a name. And I need your story, who are you guys?" Junior told them.

The boy just smiled in relief.

"Well there's not too much to say. The names Kai; Kai Emblem and he's Greninja over there."

Greninja raised his front foot.

"Sup."

"And as for our story." Kai continued. "… Let's just say we're some unlucky guys who have lost our way and are trying to get it back."

"That it?" Junior asked.

"Pretty much." Greninja answered.

"No wait!" Kai interrupted surprising Greninja and Junior. "Greninja's not my only friend with me."

Kai gestured to the other balls on his belt.

"I'm no huntsman. I'm a Pokémon Trainer!"

And that to those still reading has been the prologue of my first ever fanfiction!

*Crickets Chirping*

Wow tough crowd. But back to what I was saying at the top of the page (remember that) I should probably mention that the first two arcs of this story have already been completed. Those being the 'Intro Arc' and the 'Semi-Volume 1 Arc'. I have done this for two reasons:

Firstly it's so that anyone who's dedicated to reading this doesn't have to wait that long for updates. There are thirteen chapters after this one that I will try and post once a week, they're of varying lengths unfortunately but they will mostly be longer in the future.

The second reason is that I don't really know how far this story will go. I have ideas but this isn't the first time I've had a really good idea and then just burned out. Or what if people hate this story, do I really want to be spending so much time and effort into something that people don't want? But I figured that if people do end up liking this and I decide to stop; then I might as well give them a sizable amount for them to enjoy instead of a couple of chapters.

As for when I finish the second arc of posts... Who knows? This may become a hit and I'll start writing again while I'm posting, or this could be a one-hit wonder. Regardless I hope that you, yes you behind the screen. No not that you, you the person next to you. Have I got you? Good! I hope that you have enjoyed and will enjoy the future adventures of Kai and his Pokémon for however long this story lasts. So until next time this is Kallerston signing out!
