Hello everyone. Spatialphoenix here, and this here is my very first attempt at writing fanfiction. Writing is in fact a hobby I've had for a few years now, and while I haven't gotten to publishing or anything like that I have cranked out quite a few original stories.

The inspiration for Arcs of the Moon actually came from both my love of the two series it entails (Pokemon and Rwby) and the idea that Jaune Arc would be a much better pokemon trainer than he is a Huntsman, and could do a lot of good for the pokemon world, which will be explained more and will b clearly visible over the course of the story. I'd like to clarify that this fanfic will be taking place primarily in Alola, calling in elements from both Pokemon Moon, Pokemon Ultra Moon, and the Pokemon Sun and Moon anime, as well as canon Rwby, Grimm Eclipse, and a few dabbles of Rwby Chibi, as well as my own takes on certain elements such as Jaune's Semblance, which will be unlocked and used, as well as the black Z-Ring and the multipronged Z-Crystals (Like the ones for Dawn Wings and Dusk Mane Necrozma's Z-Moves), which may diverge from Canon. I might also use elements from fan-made games such as Pokemon Uranium.

Please note that I own nothing except for the storyline and the OCs I create; Pokemon belongs to Game Freak/Nitendo, and Rwby is the property of Rooster Teeth.

Another thing is that I'd appreciate any constructive criticism, as I'm quite new to this, and I will take given advice seriously and try to better the story in any way I can.

That's all for now folks so please enjoy,

Arcs of the Moon

Prologue

Deep in the confines of an artificial island known as the Aether Foundation, a young girl sprinted down the main walkway of a facility constructed mainly of a pearly white stone, panting as she ran as hard as she could, her steps echoing through the empty floor. She was clad in a white sundress that reached her knees and a rather silly hat, clutching a large Pokeball-themed gym bag draped over her arm. Her blonde hair was let down her back but two braids of equal length framed her face, slightly moist with sweat. Her emerald eyes were alight with the flames of both excitement as well as gut-wrenching fear as she ran further along the length of the path she was currently on.

"Have to escape this place... Have to keep it safe!", she muttered to herself, shaking due to a mixture of equal amounts of fear and adrenaline.

The girl skidded to a halt within a strange platform, slamming the controls to take her to the next floor, even as she saw several men and women sprinting right towards her. With a rather large lurch, the elevator platform she had walked onto suddenly began moving upwards, providing her a brief respite from her rather determined and stalwart pursuers. The girl took a moment to catch her breath, trying to regain as much stamina as she could in the few moments the chase was on hold.

She arrived at the topmost floor of the facility, which housed a beautiful environment filled with lush, vibrant and green plants that bloomed with flowers and hummed with life. Crystal clear water flowed in and out of the room, allowing all sorts of Pokémon to thrive within the area in peace as well as harmony, without competition for basic resources. It appeared to be a tranquil preserve.

But she knew better. It was a prison, a testament to mankind's cunning; a nightmare factory disguised as a haven. A place where countless suffered by the hand of a madwoman and her henchmen, even as they appeared to prosper. She took a quick glance around the area, quickly trying to deduce the quickest route out of here. As the gates shut down around her, a small pair of curious eyes peered up at the girl from within the bag, wondering why it's companion was in such a hurry and where they were going. The naive pokemon wondered if they were playing a game of sorts. Like tag, maybe?

Quietly stepping through the path, she remained as silent as she could, hoping to not drawn any attention to herself or the Pokémon she held within her bag. Sadly it was for naught, as she heard multiple snickers behind her and whirled around to see two of the guards in white uniforms standing right behind her, pointing in her direction. With a nod, the two men began running towards her, making the young girl turn on her heel and scurry off in the other direction.

"No, no, no!" the girl hissed, tightening her grip on her bag as she willed herself to go faster. But it was all for naught. In her fear, she had made a mistake, losing her way in the twisted labyrinth of the facility she was in.

And now she had reached a dead end.

The girl turned to the left, gritting her teeth, steeling we resolve and forcing herself to keep moving despite the searing pain in her legs and stomach, her stamina being taxed to the limit. She had to keep moving. Keep running. She had to escape.

She continued along the path, wheezing in pain, but still maintaining her breakneck pace, until she saw another guard in a white uniform ahead of her with his arms outstretched and a triumphant smirk on his face. The girl gasped and turned behind her, only to see the two guards before, one of them wearing a maniacal grin on his face as the two of them approached her.

"I'm sorry Nebby…", the girl thought as the men slowly approached her, grinning as they knew she had no way out.

"I... failed you."

Suddenly, a strange hole, glowing purple on the outside but blue on the inside, with a grid-like pattern on it as if it was made from graph paper, opened up, seemingly tearing right through reality, right behind the lone guard in white, and two people jumped out, one of them knocking out the guard with a swift chop to the neck and kicking him aside.

For a moment the chase was forgotten, as the three people and one pokemon who were already there stared at the newcomers.

They looked like they were wearing space suits, white with cobalt patches here and there and a strange logo like a bar of wi-fi with a stick coming from it on their shoulders. The one on the left was obviously female, with blue-purple hair framing her face and coming down along her left side. Her partner was obviously male, with a thick mustache and goatee of the same hair color.

"We apologize for the ah, abrupt entry, said mustache-man with a thick British accent (or the closest thing to it in the world of pokemon), twirling said mustache in his hand. "Oh but where are our manners; I am Phyco and this is my partner Soleira."

The three snapped out of their shock, and the girl with the bag knew that these newcomers couldn't be friendly, even if they did knock out one of the guards chasing her. She began to inconspicuously look for a way out, muttering a curse under her breath when she saw that none was available.

The two guards behind her came to the same conclusion; they were after the subject as well, which meant they had to get it first. They looked at each other and decided to throw all subtlety out the window. The test subject needed to be recovered now.

"Give us the bag!", both the guards as well as Phyco and Soleira roared at the strange girl, causing her to flinch and hold the bag tighter.

The two opposing forces then stared at each other, forgetting te girl momentarily.

"NO, give us the bag!", they yelled again in unison, then glared daggers at each other.

"The test subject belongs to the Aether Foundation, and by extension, Madame Lusamine. So we will take what is ours.", said one of the white-clad guards.

Soleira broke out into laughter, hunching over and clutching her chest. Even Phyco was chuckling, though it was hard to tell through the mask.

"You fools don't even know what that pokemon is capable of... but we do, and it is necessary that we procure it."

While they were arguing, the girl had fearfully begun to try and cut through one of the habitats to escape when she caught sight of a strange light coming from within the bag, which meant the pokemon inside had been given enough time to charge up its power. It was small at first but quickly began growing brighter, a mixture of purple-blue lights swirling within it. Soon the light enveloped the girl, forming a dome around her and growing larger and larger, cobalt and violet hues dying the mysterious barrier surrounding her as a strange thrum, like that of an airplane, filled the air, sending shivers down the spines of every one present, save the girl, who was just fine at its epicenter. The guards as well as Phyco and Soleira flinched and braced themselves, but then as the barrier exploded outwards, it quickly dissapated and seemed to fly upwards as it merged into the inky darkness of the night sky...

The two guards stared up into the sky, bewildered at what they had just witnessed. Phyco and Soleira, however, let out growls of annoyance as they realized that the target had Teleported away, leaving them at another dead end. They then slowly turned to the people who they felt allowed the target to escape. The two guards shrunk slightly and flinched at the intensity of the glares that the two strangers were giving them. After a few moments, Phyco spoke, his voice tight with anger and his suave demeanor shattered.

"You utter imbeciles allowed the target to escape!" he shouted, unhooking a pokeball from his belt.

He turned to his partner, who nodded at him in agreement.

"So allow us to demonstrate what happens to those who get in the way of the Ultra Recon Squad.", said Soliera, unhooking a pokeball from her own belt.

The two guards nervously raise their own pokeballs and got ready to fight the strangers...

And the night sky was laced with the sound of their screams...

The next morning...

"Ma'am… we have three dead guards up here, and the test subject is gone.", said one of the guards sent to check up on the team, a nervous undercurrent in his voice.

"What?!", Came the furious reply from the radio, making the guard on the other end shiver from the force of his boss' rage.

"Lillie", she spat out, and a scream of psychotic rage echoed through te radio, making the guard consider resigning from his job. He heard Kanto was nice this time of year. "That horrid little BEAST has gone too far!", she continued, beginning to rant. But the guard luckily interjected before she could begin.

"The guards were killed by corrosive poison, mam, something that the girl isn't capable of procuring. She may have taken the subject, but can't be responsible for the deaths. We think the test subject may have been responsible, but the possibility has been deemed low as the subject hasn't shown any indication of being able to produce poison from our prior tests, ma'am."

"Has the poison been analysed?", she asked, all traces of rage gone but with a strong undercurrent of curiosity.

"Yes mam", replied the guard, relieved that her rage had blown over. "Chief Faba and the forensics team were alerted immediately. They say the poison doesn't match that of any known pokemon, including legendaries and megas. Even the poison component of the Null Project aren't capable of creating such a poison."

"Very interesting", came the reply, and he could almost hear the president's musing before she gave him a new command.

"Continue to search for the subject, it has a connection to my darling and I will find a way to unite with it. Until then, keep me updated on any developments with regard to the missing Null and the... other project"

The radio clicked and Lusamine leaned back in her chair, steeling her fingers at the latest information. The little wretch would pay and be put in her place, she decided, but first she had to see about this strange assassination. Normally, the deaths of her employees wouldn't have bothered her, as Wicke dealt with the paperwork from that, but the fact that it was the work of no known pokemon even among legendaries and such certainly caught her interest... and let it be known that Lusamine was a person who never let up such interests... And she looked to the sky as she began to plot on how to reach her little darling...

Deep in the voids of space and time, Arceus sighed, mostly in relief but with an undercurrent of frustration. The girl and Cosmog had escaped, but the Ultra Recon Squad had showed up, something that wasn't supposed to happen. It was against the nature of the timeline, for they were from another world. But their interference would cause ripples, and Arceus didn't need the ability to see into the future to know that his chosen hero, Moon, whom he had decided to put into play to stop the threat in Alola, wouldn't be able to prevail against such odds. It was simply too much with the added interference from the Ultra Recon Squad and by Extension, the Dark World. Arceus knew that Phyco and Soleira were only foot soldiers compared to the horrors that could be sent from the Dark World, and Moon would never be able to stand against them. The truth is, Arceus' chosen heroes were more interested in becoming the champion of their respective region as opposed to stamping out evil, which wouldn't fly in this situation. But something needed to be done, so that the world of pokemon didn't fall...

"Penny for your thoughts, old friend?", called a voice from the blackness of the void Arceus chose to occupy.

Arceus blinked and gazed upon the newcomer, tilting his head in friendly amusement as he beheld his guest, a black haired man wearing a tuxedo, with an Asian look to him.

"Monty", said Arceus, greeting his long-time companion. "What can I do for you?"

Monty smiled. "Actually, I'm here to do something for you", he said.

"Oh?"

"I couldn't help but notice your plight, Arceus. The other side are meddling with your world, and you know as well as I do that the Ultra Recon Squad are but the first to come. More dangerous enemies will follow, and no ordinary pokemon trainer will be able to defeat them."

Arceus sighed. "You're right of course, and I honestly have no idea what to do. The people of my world aren't equipped physically and mentally to deal with this threat."

Monty smiled. "No, but the people of my world are."

Arceus looked at him sharply. "What are you suggesting?"

"A transfer. There is one person in my realm who is rather... out of place in my world, but is perfect for yours. My world's timeline will be altered drastically, but ultimately good will still triumph over evil. I'm willing to make this sacrifice, however, so that your world doesn't fall. This is the only chance the pokemon world has at survival."

Arceus knew, partially due to his omnipotence, and partially due to the strange power known as common sense, that Monty was speaking the truth, and he needed all the help he could get.

"Who do you suggest?", the pokemon god asked finally.

Monty snapped his fingers, creating an image of a blonde, blue-eyed boy with a goofy smile.

"Jaune Arc."
