Okay, this is a bit of foreshadowing for how the kingdom hearts games will go, but again, if you're a kingdom hearts fan, don't think, this is how the game will end, i'm just using a much darker ending for the series could go. I for one can't wait for KH 3 game and i've pre-order it, so can't wait! Anyway, this will be a long story, with xero being younger for reasons, but a full fledged keyblade master and user of the darkness. Why? Because, light and darkness, in my opinion are one and the same. If xehanort was right about one thing, it's this: darkness can't be destroyed, only channeled. He was right, just don't let it control you, and DON'T Become an asshole like him. Anyway, i will need other characters form different anime's to fill out both the harem and the first year's and both allies and enemies. As always, i don't own RWBY, kingdom hearts or any of the characters form the different animes.

Chapter 1:The hooded hero

Blake belladonna was a conflicted young woman. She knew what she wanted out of life, make no mistake of that.

She wanted peace between her race, the Faunus and the other race, humans. The white fang, an organization her mother and father created whose soul purpose was to be the bridge between her people and humans.

But it wasn't that simple, even after everything, after the great war, after the years the white fang was formed, things only got better a little bit. Faunus are still treated like freaks by people, the SDC, still have faunus treated as slaves, rather then workers and those in power did nothing.

So, with little to no results, Blake's father, Ghira, step down and sienna khan took over and things began to change. And not for the better. The people began to respect the faunus, but out of fear then wanting to.

Peaceful protest's turned to all out war against all those who disagree with the white fang, and began killing people, both human and faunus alike. In Blake's opinion they were misguided and simply needed time.

However, not everyone didn't agree, especially what's many people have come to call the "hooded hero" a person, in a black coat, wielding a strange Key shaped blade, with what appears, to be an element semblance, but no one's confirmed it. Hell no one's even knows his name, as he or she calls themselves," I'm nobody."

He or she was not a big fan of the underworld, nor the white fang either. As he's not only put a number of them in jail, they've turned more then a few against them and even killed the more...ones that think like Adam. He or she has even stopped many raids all over remnant as well, putting them on their shit list.

However Blake began to have second thoughts, as many, both human and faunus praise the hooded person, as their hero and even began to become more friendly with one and another. Those who have hated each other for years, now act like their cousins and are actively opposed both the white fang and those who are still racist, and thus doing what the old white fang tried to do.

Bring equally and peace between the two race's. Hell people have also began to oppose those in power, who try to kept faunus down, making those in power, very nervous and wanting the young vigilante to be put behind bars, but it was getting more and more difficult, as many are now supporting him. It did piss off a few people and one of them being the white fang.

For one, they have tried for years to achieve result's, and soon they go down their current route, some nameless person pops out of the blue and some how undoes years and years of hate in just under a year? It was infuriating to say the less. Oh and don't get her started on their personality either.

Their rumored to be cheerful, taunting, not a care in the world and what's worse, even the strongest among them, get beaten with one or two strikes of that odd sword of their's. It was very infuriating, and it doesn't stop there either.

They've been said to wipe out entire hordes of Grimm, in the blink of an eye, saving villages all over. How can someone so strong just appear out of no where without anyone knowing?

It's an unspoken thing, but when someone powerful, one that can kill powerful Grimm, tend to become quite famous, yet here was someone with an unknown weapon and abilities that just can't be a simple semblance, tends to draw attention to one's self. So how the fuck has they've hidden for so long and just now come out of hiding. And what's more, is their said to be able to sense the Grimm.

That, made everyone who considered the Grimm an enemy, which was everyone, made him invaluable to many, as he could tip the scales in humanity's favor. the Grimm, are apex hunters, they sense humans/faunus not the other way around. To hear such a thing, it was inconceivable. That spurred the hunt for the hooded person even more. But at the same time, it came with it's own problems, as the grimm, seem to go to him, like flies to a fly tarp. Grimm seem to be even anger at him, or quite possible...Afraid of him, making them even more desperate to kill him. If that was true, it sacred Blake.

Just what in the name of all that is good and holy, could be so strong, so powerful, it sacred the beasts of extinction? It really painted a terrifying picture for Blake.

The hooded hero, was an unknown and to many, an unknown was a danger to everyone. At least to a few in power, especially atlas, as they've sent a warrant out for their arrest. It was more of bullshit charges, as many could see he's done no wrong, thus is invaluable, and those in power who have been helped by the hooded hero, and are pressure everyone to drop the charges, but atlas was the most stubborn of them all. The fact, he could sense grimm, only made them more desperate to find them, and find out how he can do it and harness their power. Huh, jerks.

One of the hooded hero's support's was the headmaster of beacon, ozpin, who felt this young person has done nothing but good and should't be arrested for simply being an unknown. He believes that the unknown should be welcomed, not aliened for simply being different, that only causes trouble. And turns potential allies into enemies. It's been proven, with how the white fang's taking a turn for the worst.

Many have given up trying to arrest, as after on year, many of the people, human and faunus, men and woman, even huntsman have all thought, it was best to leave him alone and just let them do what they do best. Only atlas, hasn't given up, but are more discrete about it.

Stubborn bunch, i'll give them that.

Anyway, after much thought, Blake has come to one conclusion, the white fang and Adam, she once knew, are both long gone replaced by these monsters. So on today's mission, she would do what she always do: runaway. After hearing how Adam simply disregard innocent lives, it showed her, he's change and not for the better. And after finishing off the spider drone, she was going to put her plan into action.

However, her plans have hit a bit of a snag. As after destroying the robot, they heard the sound of...clapping?

"clap,clap,clap,clap, alright, fight,fight,fight." Spoke a new voice, causing, the two faunus to turn and, "It's them!" And sure enough behind the duo, clapping their hands, was a person, clad in a black jacket,pants,boots and wearing a hood completely covering their face. He had a sliver chain around the front of his hood.(Think organization 13 coat.)

"Gotta say, i'm impressed, not only with your teamwork, but you're semblance's really compliant, one another."Their voice sounded male, so the duo assumed it was a he. In a show of pure confidence he jumped of the large box,standing up to their full height of 6'0 foot tall. But it also put the two faunus off, did he not know who they were, and thought he was in no danger.

He more then likely seen what they can do, so were they just not a threat to him? Did he think they were nothing? At that thought, Adam got anger, as he pointed wilt at him. "Who are you?" he demand, as the man, boy maybe? Just simply gasped mockingly, as he said in a tone, like a parent scolding a child.

"Now, that's just rude. Don't you know, it's impolite to demand anything?" He even add a waving finger, something that severed to piss Adam off more. As far as he can tell, the pain in the ass for the white fang, was just messing with them. They were no threat to him, and he knew it.

"Then, why, why are you here?" Asked Blake in a calm voice, causing him to look at her. She thinks, hard to tell, with his hood covering his entire face. He clapped again, and said,"Ya see, that's how you get answers, by being polite." It did nothing more but piss Adam off even more, as he continued, " So as to why, i'm here, well it's quite simple." Then the air turned form joyful, to tense and cold, as of the air turned form warm to down right frosty.

"You two are here to steal this dust." His voice, was also replaced, form carefree and happy, to down right cold and menacing, as he VANISHED, form their sight, causing the two to look around, only to freeze upon feeling gloved hands on the back of their necks. "Dust, that not only makes it harder for people to get, but gets those who need it, be it human or faunus, who have nothing to do with this, killed. All for you're so called righteous cause." He spat out, like he sallow something foul and disgusting.

Then before either could react, "Boom" A sudden explosion, and the two faunus were flung back into the wall, their aura's flicking to life, protecting them form any permanent damage, but still hurt like hell.

As the two slowly got up, they saw, what has become the end for many Grimm, human and faunus alike. A black sword in the shape of a key. It had a bladed guard, with red and purple gems going up the spine of the sword, with a cage like style at the end, with a pointed tip. The key chain at bottom of the halt was black, holding a red wolf head, howling, within a red spiked circle, his personal symbol.

The two stared, the fuck did it even come form?

With a roar, Adam, shot forward, raising wilt on a down word arc, the man simple brought his odd sword up, making a loud"clung" as sparks appeared, Adam, struggling to hold, as the man didn't even budge, not an inch. Blake tried to come up form behind, but with a simple spin, he knocked back, both opponent's like they were flies. Her aura shattered like glass as a result, as she slammed into the large container, with blood running down her forehead, as her head slammed into it.

The sheer force of the attack made Blake puke out blood. Oum above, it was like getting hit by a goliath, and it was nothing more then a single punch. Her eyes widen in horror, just who what is this guy?! And just what in the hell, has she gotten herself into?!

She knew, while she had a little higher then average aura pools, something normal for someone her age, she knew a normal attack would't have just shattered it like it was glass. It just should't be possible, yet this man, no this monster had just proven her wrong.

"Clung,clung,clung." She was brought back to the present, as she saw Adam, also bleeding form his lower lip, as the hooded figure broadly block each of the bull faunus strikes, till "Blizzaga" and Adam was once again sent back, only to have his entire right arm and wilt frozen. It was shocking to say the least, but the man didn't give Adam, the chance to break free, or even try to, as he was upon him, fist cocked back posed for a punch.

Naturally, he rolled out of the way,"Crack" Barely avoiding, an earth shattering punch, as the train car rocked a bit, but other wise kept moving, scaring the living hell out of both faunus, both thinking they've really, really in over their heads in facing this man, no this monster.

"He can't be human or faunus." No one had strength like that, it was simply inhuman. No one, had ever displayed such feats and the man wasn't even winded!

"W-what the hell are you?!" Adam yelled, as the man simply stabbed his sword into the ground and said simply," I am nobody. No i am the living retribution of all those lives you've taken, human and faunus alike. Those who lost their lives for your pathetic cause of bloodshed. Let me tell you something Adam taurus , you aren't the solution, you are a problem, along with the rest of your followers, and as such, must be purged, so you can't hurt anyone ever again, now DIE! Oblivion ball!"

The man shot and black,gold,red orb form his free hand, but Adam did something unexpected, as his arm, that he'd been thawing, had broken free and rather then dodge, he moved wilt to absorb the energy ball meant to end his life, turning it into power. If his glowing hair, clothing and sword were anything to go by, he got alot.

"Ha ha ha, fool, you've done nothing but give me more power then i thought possible." Blake looked on and shock and the man... not sure, can't see his face, though he did tilt his head, if only a little. "NOW YOU DIE!" Adam went charging forward with a super powered wilt and blush, and went for a killing blow with blinding speed.

"CLAP." So image Blake's complete and utter surprise and Adam's as he their opponent simple caught the blade, with...HIS. BARE. FUCKING .HAND! "Is that all?" he asked in a tone, full of boredom, as the red blade began to crack. Both faunus were simply stunned into silence, A feeling began to well up in Adam and it wasn't hate.

It was Fear. Simple, fear that gripped his heart,mind body and soul, filling it with an unknown sensation, as he and Blake began to tremble. And no one can blame them. It's not everyday, you see someone, brush off an attack that can destroy entire war machine's into dust with a single thrust, only to be brushed off, like it was a fly. So yeah, in short, the hooded hero was an absolute terrifying enemy.

"W-what the hell are you?!" Adam yelled again, but this time, fear laced his voice, as Blake was simply to afraid to move. His response was this,"C-crack,BREAK." to shatter the red sword, with only red dust remained, as Adam, fell back due to both loss of balance and fear crashing into him, as the man simply summoned his blade again, in a flash of dark light, as he said simple,"I am nobody." But then Adam did something unexpected.

He threw the red dust at the hooded man's face and without seeing if it worked, ran and jumped off the train carts.

The hooded man just stood their for a few seconds and said, while de-summoning his blade,"well knew, he was a coward, but that was unexpected, sigh. All well, their's always next time." With that, he silent opened up a portal, made of black and purple flames, before stepping through it, as he left a very, shocked Blake belladonna alone, wondering one thing.

"What just happened?"

Slowly, Blake pulled herself up, holding a hand to her ribs. Yep at least three broken ribs and possible internal bleeding, she frowned. Damn, that guy just simply can't be human, aura or not, if he was aiming to kill her, she be dead on the floor.

She shivered, but sighed in relief, it was over. Sure, her leaving the white fang wasn't going to be like this, but it would help her get to vale now, Adam would wait a while before, he realized she had defected. By then she be in beacon and would't make a move, while on beacon grounds.

He might be bloodthirsty manic, but he wasn't stupid enough to attack a huntsman academy. Right?

Shaking her head, Blake knew, she would never cross paths with that monster again. Clearly he was here for Adam and not her. Which was good, meaning he'd have no reason to come after her again. Hopefully.

Poor, poor Blake. You've got no idea how wrong you are.

With the hooded man

The hooded man stepped out of the portal, into a fancy apartment, before pulling back his hood. Long pitch black hair, in the shape of a raven's quill's spilled over his back, reaching past his knee's. It has six sliver streaks going through his hair in an even fashion. His pale skin went well with his blood red eyes, that had four redder lines going to his pupil(Basically like the founding titans user eyes in attack on titan season 3.) He had a young face, looking to be about 16 or 17 years old, with a small "x" scar over his right eyelid. He sighed, as he pulled his coat off, revealing his true outfit under nether. He wore a black choke collar with a golden cross being held by a sliver chain, with an equally blood red gem with a silt pupil in the middle.

He wore a black sleeveless shirt that hugged his slender but muscular body, that had a 12 pack hard abs,, with red buckles at his board shoulders. His right arm had blood red armor, that of a knight, but smaller, covering his arm with a large button shape on his shoulder armor. He wore a black belt, with a sliver chain, and armored red and black combat boots, but only at his feet, as not to hinder movement.

He had a black chain tattoo on his left arm, going form his wrist to his shoulder, where on his neck was a red wolf head, howling, within a spiked circle. On his right arm was a black flame tattoo, going form his palm, up his shoulder, where it connected to a purple flame tattoo, that went up to his neck.(Think Revy's tattoo form black lagoon.)

He was also a faunus, with four visible traits, of a black red tipped tiger ears atop his head, with two ear clamps one sliver and the other clear. His nails were claw like painted black, a black red stripped tiger tail and his pupils were silted. he had visible black tiger strip's across his arms and the back of his neck.

This young teen, was named Xero Mazoku, the Keyblade grand master, the first Keyblade master to use darkness and not fall to it and the last of the guardian of light. The other six were unfortunately destroyed during the second Keyblade war and the final battle against the 13 darkness. And he was human, but how he turned into a tiger faunus with more then one animal trait was beyond him. He just figured it was one of the "Rules" upon entering this world, after he escaped the realm of darkness. He was 21 years when he fought in the second war, but he regressed back to a teen to now being 16 going onto 17. Again, he had no idea how he became a teen again, but played it off as side effects of being in a realm with no time in it.

"Sigh, it's been a year since..." He could't finish that thought, as he gained a lost look in his eye, looking at the setting sun, thinking on how all this happened. Since the war, since he was banished to the realm of darkness by a sore loser, since he lost everything.

The final battle against the 13 darkness, the 13 different versions of xehanort against himself, Riku, Lea(Axel), Kairi, king Mickey, Donlad, Goofy, Aqua and an awaken Ventus to fight them. The battle was long and hard, but soon they were able to defeat xehanort, but not before, he destroyed everyone and in a last act of spite, banished xero to the dark realm. After a bit of wandering around, he found a hole in the realm and escaped to remnant.

He spent god knows how long in the dark realm, to the point he de-aged back to a teen again. He merely assumed it was due to certain effects the dark realm had on people. But his past mistakes being shoved in his face, were without a doubt, the dark realm's doing in trying to break him. And it almost worked too. Especially when it showed Riku's final moments, the idiot using himself as a human shield against the younger xehanort's attack.

Not that it mattered as after Riku fell, the others followed shortly after, and with his anger rising, xero did something the 13 darkness didn't expect.

He used the power of darkness, but combined it with his light powers to create the X-Blade, the guardian of kingdom hearts. He accepted the darkness in his heart, made peace with shadow xero and truly became one, to reforge one of the very first Keyblades and defeated the 13 darkness. But not before he was banished to the dark realm.

Anyway, while fighting a horde of heartless and letting lose a stray spell, it cracked open a hole within the realm, allowing xero to escape to a new world, a new dimensions all together, where he was transformed into his new form and has stayed ever since. He had no problem with being a faunus, as he's been turned into other things, such as a merman, a walking Halloween decoration, A lion cub, a walking card, a dice, hell even got turned into a five inch toy for crying out loud.

So while born human, he was pretty much use to being something else entirely, so having animal parts was no problem to him. Being able to see in the dark, his sense's enhanced and having claws for finger nails, was just a bonus.

However some people didn't have such tolerance as him. And quite a few tried to make his life hell, but with everything's that's happened, he still friendly, he was much more ruthless and would't hesitate to kill someone. It's that same hesitant that got everything taken form him. Hence why he took it upon himself to not only stop the white fang, but kill all those who deserve death.

Those who like to kill innocent people, the rapist's, bandit scum, etc. But as of late, the white fang has been getting desperate and recruiting younger and younger faunus, he decide to do something about it.

Not killing them, mind you, they had no idea of what they were getting themselves into and helped them see that before it was too late. In just under a year, he had earned himself a reputation as both a Grimm killer, slaughtering entire hordes of Grimm, to stopping crime, the common folk have followed his example and have taken it upon themselves to stop the criminal's.

It made him a vigilante for sure, and the fact he can sense the darkness inside the Grimm, aka the Grimm themselves, it's made him the most wanted man on remnant, with the search slowly declining, with only atlas, that Pyrrha nikos and that amazon girl looking for him. Oh and half the underworld and white fang to kill him, but who was he kidding, trouble always seem to find him, no matter what world he's in.

How could he sense the darkness you ask?

Well, one does not spend the better part of nine years doing nothing but going form world to world and destroying the heartless and even his time spent in the realm of darkness, with his newly acquired darkness powers, you tend to pick up a thing or two. Even then, master yen sid mad sure to teach him, EVERYTHING their is to know about in using the powers of the Keyblade and shadow xero, after their merging, gained access to power he didn't even know he had. But yeah he was being chased by three people he can say by name.

Atlas, for his abilities, Pyrrha, because he beat her, with only a single punch to the face, with enough force to knock out an enraged goliath, to get a "Rematch" not that it make much difference, and that amazon warrior girl, for the same reason, only he humiliated on purpose to knock her down a peg or two. Of course that just made her madder, and she swore to hunt him down to the edges of remnant to see he pays.

His response? Bow mockingly and said," I'll be waiting" And left a swearing amazon, cursing up a storm. So after a while, he took up home in this nice apartment in down town vale. after coming out of his thoughts, he decide to visit that shady bar in the bad part of vale, where a man called hei xiong aka Junior, had an information on everyone.

Maybe, it's time he paid the man a visit. And hopefully figure out why he felt like he was being followed!

Unknown to xero, a raven bird with red eyes was following his every move.

My fucking god, took me a mouth to finally write all this down. By the way, all thoughts i had about how easy this is, and insulting you writers, i take it all back, Big fucking time. So yep, this is my second story and it'll be a long one. Next, xero will meet the sun dragon and things will go about as well you expect,"BOOM".

Devil out.
