Author's Note: Well, this idea among many others has been bouncing around in my head for quite a while, but this one was the only one that seemed to have a lot of staying power. This isn't going to slow down the Modern Warfare LP fic, it's essentially something I can work on whenever writer's block hits me for that story, and is in some ways easier to work on since I don't have to look at gameplay footage to find ways to transcribe.

Not that this is going to be necessarily easier as a whole compared to the Let's Play fanfiction. I've got to figure out how to get two completely different worlds, Pokémon and RWBY, to interact with one another. I've got to think what characters from those series or possibly others I want to throw in and have interact, the plot, a great deal about the environments, how to interpret the various moves in Pokémon in a non-turn based environment, that sort of thing.

And Yang feels like the best one to throw into this strange new world to me. I look forward to exploring the non-asskicking part of her character as she begins her journey.

As a side note, I'm not too much of a fan of how Fanfiction net's crossover thing works. So for now at least, the story's staying in the RWBY section since the main character is Yang Xiao Long. Hope nobody minds.


Chapter 1: Crossing Worlds the Accidental Way

Science was in its own ways a battle. At least, that was the general consensus of most scientists. A combination of caution and audacity that was different from one researcher to another. Though perhaps that way of thinking was just an effect of Pokémon influencing humans.

Whatever the case, Bill felt confident enough to test just how far at a time his new transfer device could go, but not quite confident enough to test it on anything living. He'd already checked if it could go from Saffron City to the Indigo Plateau. Now for something further, from his lighthouse lab near Cerulean to Professor Elm's lab in Johto. If everything continued to follow his expectations, by the end of the month he'd check if he could sent inanimate objects from Kanto all the way to Unova.

Item transference was only the beginning. Eventually he hoped to be able to transfer Pokémon and even people all over the world. He could just imagine it, a world more connected than ever before, where even the most extreme distance was as easy as the push of a button to overcome. Cultures, people, and Pokémon, truly unit..

..well, that was disappointing. The instant ramen on the counter wasn't teleporting. The equipment was clearly running, the fans to keep it from overheating were going loud. A little louder than his last test come to think of it. Did he run into the limit of what his technology was capable of at this stage of development? Not entirely unexpected but still disappointing.

As tempting as it was to poke at the plastic cup, he'd rather not risk losing a finger if the transfer happened just as he touched it. Thankfully the phone was right next to his computer. He could examine the readouts while calling the professor to see how things were on his end.

The phone didn't even finish the first ring. "Doctor, I could have sworn you said we were sending something small in this test."

Definitely not the hello he was expecting. "Yes, I was wondering why it hasn't gone through already! Everything's registering as green on my end but I'm not seeing a blinding white light as it teleports."

At least Elm didn't sound like he was in a panic, just confused. But then this was the first time he'd seen the equipment running and trusted Bill to know what was happening. "The equipment isn't registering any problems. At least nothing your list of potential problems would hint at.."

Great, so whatever was going on was something his calculations and various paranoid imaginings didn't come up with. That was comforting. About as comforting as seeing scavengers flying overhead and clearly expecting a feast soon.

"..but did you say 'blinding white light'?"

Something other than what he'd seen in the thirty-six successful tests. Wonderful. "Yes. What are you seeing?"

"Well, it looks like one of those cheesy science fiction portals above the point on the table you intended. Some kind of glitter around it. It's also noticeably not blinding."

It should be emitting light right at the spot the ramen was supposed to flash in at. Hell, the transfer should have happened at the same speed it took for his voice to travel by phone! And even if there was some kind of inaccuracy like the Coriolis effect, it shouldn't be in the same room but 'larger' and 'higher'. "..above? How far above?"

"It's between the light overhead and the actual ceiling. I'm surprised it's not affecting the electrical current powering the light, but it's still rather..concerning. It's sort of disk shaped. large enough I could throw my bike into it. Hell, I could probably ride my bike 'through' it if it was at ground level. I can't really say what color it is..it's shifting colors so much and going through more than even a rainbow would bother with. Does light count as light if it exudes darkness for a few seconds? That isn't my field."

Something resembling panic began to grow in Bill's chest. "Well at least we aren't accidentally angering something like Garatina, that would be a bit more distinctive. Since none of my equipment is reading anything wrong, and the equipment I sent you isn't reading anything odd, I don't suppose you have anything in your lab to try scanning what's actually happening, do you?"

It was grasping at straws and both of them knew it. He didn't know how Elm felt about that, or if he even caught that Bill was just as much in the dark as him. If anything he sounded embarrassed that he didn't think of doing something like that on his own. "Yeesh, I'm not really one to focus on anything other than Pokémon biology and abilities. Still, I might have..hold on."

Every second felt like an eternity, especially when the more cautious part of his mind was telling him to shut the machine down. As informative as learning what was going on and trying to figure out how it happened might be, the fact of the matter was that it was 'very' much something he wasn't prepared to deal with. Something completely unknown. And he was putting Elm and his assistant in potential danger to satisfy his curiosity. If it was just himself, he'd be eager regardless of consequences..

"Right, think I found something. It's typically used to figure out what type of Pokémon are in a two kilometer range..it's getting plenty of readings of numerous Pokémon beyond the portal, seems to be hundreds. At least it's not the distorted world, that would register tens of thousands right on top of eachother."

That still didn't make Bill feel all that sure about what was going on, or ease his conscience.

"Not sure why I'm not getting too much detail, I'm doing all I can to give this thing an extra boost in range and I'm getting too much static to say much more than how many Pokémon detected. There's maybe a fire type somewhere in that mess but..okay..now that's interesting."

Interesting. Such a double-edged word that could sum up pretty much everything from a baby trying to imitate someone to imminent death. "Interesting as in worth taking a closer look, or interesting as in we should both cut the power to avoid something dangerous happening?"

"Well, that fire type has to be 'very' powerful, but the static is moving. It's not interference, it's a swarm of some kind that..well, for lack of a better way to put it, registers as void."

Not darkness or ghost type. "..void, professor?"

"Well it's certainly not human, it's not any of the Pokémon types we know of. It seems to almost suck in the energies of everything around it. And there are a 'lot' of them. If I was younger, or had a damn good team on hand, I'd check to see if I found some new breed of Pokémon in an alternate dimension, maybe set up a research post on the other side, but I've seen more than enough horror movies to think I'd be able to do anything and be free to get back out. I'm also getting some odd psychic readings. Omnidirectional. Not just from the portal."

Definitely far too many unknowns to digest in a single Sunday afternoon. "Right. We'll call this experiment a failure, keep a copy of the various settings we tried today and the readings, and if we can replicate the effect try playing explorer later. For now I'd rather not.."

Bill wasn't even sure what he'd rather not. Rather not break the space/time continuum over a stress test gone weird? Rather not risk the only two people actually seeing this getting harmed in any way? Rather not make the people behind his funding decide to cut it because it was going in a completely different direction than anyone thought?

Whatever it was that he'd rather not, Elm seemed to agree. "Right, do we cut the power at the same time or do we have to cut it in a particular order to be safe?"

"Let's try cutting it at the same time. On three..one..two..three!"

If there's one thing that you can say about anyone on the cusp of being born, assuming you bother thinking about life at such an early stage, it's that they reach out and test the boundaries of their limited awareness. A kick while in the womb..or psychic wonderings while still in the vat, whatever the case may be.

The creature inside the vat wasn't really aware enough to have an identity. How could it when its nervous system couldn't tell if it was wet, warm, or the difference between a solid and a liquid? While the body was taking shape beyond an embryo, it was still not quite a baby yet.

So the fact that it didn't realize a spot it was probing was an obscene distance away would have been no surprise to the scientists that made it, at most they would have given eachother more pats to the back if they 'had' known it was looking at something so far away. Assuming looking was the right term to use. It just "felt" something that seemed "pleasant" to the only sense it had at this point, its rather potent psychic power.

Two very old, very powerful Pokémon noticed its probes and were themselves curious both about the psychic presence and the thing it was probing. That sort of range for psychic awareness was enough to make them wonder if a god was forming. Hard to say from one so young. But as ancient and powerful as they were the young mind didn't even notice. And who could blame such a young mind for being so enthralled by what amounted to a lightshow? One that its world had never seen?

Warriors of various, magnificent colors stood in defiance of shadows without number and of numerous shapes that had only enough presence to register as more than figments of a collective imagination. Weapons that were expressions of their very souls clashed with feral teeth and claws. So much to soak in, too much for even a very powerful psychic to ever have a full picture of even if it had eons of experience with such things and was actually physically there to witness it with sight, hear it, smell it.

So it divided its attention to the various struggles until it found one that it couldn't turn away from. One of the ancient ones tried to give a warning about dividing oneself like that, but that was an easily ignored distraction. What good was communication to a mind that doesn't have an identity yet?

A tired but determined warrior, standing among equally tired comrades, summoning weapon after weapon out of nothing in order to fight hollow drones that were once considered allies. Only out of sheer fatigue is the warrior knocked down, skill meaning little to the weight of numbers bearing down on them. One of the tired comrades summons a piece of a fresh warrior to help, all including the summoner are surprised. The fresh warrior dissipates, and another wave of foes comes at them. The tired comrades complain but still clash against drone and monster alike, hoping their efforts will save countless others.

A talented, peerless warrior finally being pushed to the limit against a corrupted, searing monster, not quite of the light but not of darkness either. If it was a pure contest of skill than the warrior would have won. If it was a contest of impassioned wills than it would have been deadlocked. Pure power and it would have been one sided in the monster's favor. But the combination of factors made it too close to call until the warrior took a crippling blow. Then a lethal one, the warrior's light fading. And before the light could fade on its own it was scattered in an explosion of power just to be sure the skirmish in the much larger battle was won.

It didn't matter to the young mind that it was witnessing countless deaths. How could it matter when one hasn't been born yet? What 'did' matter was a burst of energy from inside the anomaly, an uncontrolled explosion from one who 'did' care and released a power older than any on that battlefield. A burst that made even the two ancient Pokémon recoil..and jump-started the newborn's awareness. The energy carried with it a sense of anguish, despair, and flashes of memories. Memories of a place that was only temporarily connected to this planet. A name that screamed through the mind of every scientist in the building with mind numbing intensity.

{"Pyrrha!"}

The unborn creature with the designation of MewTwo nearly died before it was even born, psychically venting before the overload became too much. Trauma that would go unremembered but still leave an incredible mark. The instant they recovered from the backlash enough to stop feeling unexplained agony, every living creature in the lab, from the smallest insect to the scientists, went berserk. A woman ferally punching a random picture on the wall until her bones broke. Lab rats tearing each other apart and then contorting themselves to rip into their own flesh. The cloning lab was no longer a place of science, just a madhouse. And while the rest of the island was safe from harm, the screams could be heard for miles away despite sound not going that far..

Elm had barely touched the switch to turn off the portal when his scanner went crazy. The screen went fuzzy as its internal circuits went up in flames. Not the kind of overheated flames of overworked wiring. More like someone had been smoking next to a container of napalm, all at once and the only reason he wasn't hurt was he threw it away in shock.

Then a burst of wind from the portal shoved him off his feet. It wasn't quite powerful enough to send him flying but it came so suddenly it was like a three foot kid managed to tackle him. Thankfully there was a chair behind him. His poor assistant slammed head first against a filing cabinet, blood coming from a nasty looking cut but at least he was conscious enough to try getting back on his feet.

Elm practically leaped for the off switch, no longer caring if he'd do it at the same time as Bill. Things had definitely leaped from 'interesting questions' to 'too crazy to keep poking at'.

Elm didn't hear the cries of alarm from the phone, he just heard a blood chilling screech as the portal collapsed on itself. As if a massive bird was being eaten from the legs up, had no way to escape, and was desperately calling for help with its last breath.

Just moments before the cry ended and the portal shut, something dropped out of it. Half of Elm was tempted to rush deeper into the lab for something, probably one of the pokemon be kept around for self defense. Then he actually looked at the crumpled, motionless form. Huh, a human. At least at first glance she looked human.

Long, wild, golden mane. Rather revealing clothes over pale skin. Looked somewhere between five foot nine and six feet tall, hard to tell in a fetal position. One well muscled arm with an intricate looking bracelet, some kind of cartrages inside with some spent..and a bleeding stump where the other arm should be.

Definitely not his field. With a quick apology to Bill, Elm hung up and called a hospital. Wherever this girl came from, her injuries were beyond his first aid kit and limited knowledge of human anatomy.


Closing Notes: Yeah, kind of a cliché way to get her from world A to world B, but it's a cliché because it works. Hope you're interested enough to keep reading.
