OK, so this is a crossover story between Kingdom Hearts, Digimon Fusion, and Pokémon up to XYZ.

before I go any further, I'd like to address the few people who are going to say 'well, if this is a crossover story, then why isn't it in the crossover section of the website?' Well, I would put it in the crossover section if they would allow me to have three different tags for the three different universes. Unfortunately, they must limit it to two. So, I figured that I would only produce this story in the main category that it's in. Pokémon.

Now then, this I hope you enjoy reading this, as it took me a good two years to come up with this idea. I'll try to update frequently, but between the several stories that I'm beta-reading, it's going to be a challenge.

Anyways, on with the story!


The Kalos Region.

Like many other regions, a beautiful place where people and Pokémon live in harmony, reflecting each other's thoughts and feelings. When people smile, Pokémon smile. And when Pokémon cry, you'll find that people cry as well.

And here, a certain young man is about to arrive at Professor Sycamore's Pokémon Laboratory. A young man seeking new dreams, and new adventures.


Standing in the biggest city in Kalos, Lumiose City, was a young man who looked about 15 years old. He had on a blue jacket with white highlights, a dark blue shirt underneath the jacket, navy blue pants, black and red shoes, black and red fingerless gloves, and a red hat with a white half-Pokéball symbol on it. He also had a hopeful look on his face. On his shoulder, a yellow rat with three brown stripes on its back going perpendicular to its spine, two red spots on it's cheeks, and a tail that looks like a thunderbolt.

He walked into the building, and was immediately greeted by a small library with a couple of researchers here and there reading on a few different topics while other researchers were carrying small Pokémon through hallways, doorways, or using them to look for specific books to read.

Honestly, it just looks like every other laboratory in the world, the kid thought.

"Ash! I've been expecting you!" the child heard from one of the hallways to his left.

Ash looked for the source of the voice, and he sees Professor Sycamore, the lead professor of the entire Kalos region. He was in his mid-30's with wavy black hair, wearing a blue dress shirt underneath the signature white lab coat that can be seen on any professor known in this world. He also had on a pair of black pants and a yellow belt holding it up.

"Welcome to the Kalos region, Ash! Quite different than Kanto, isn't it?" Sycamore asked.

Nodding his head, he said "Quite, Professor. It seems that each new region contains its own share of adventures, with new places to explore, new friends to make, and new Pokémon to befriend."

"Quite so, Ash," The professor says with a smile on his face. "And speaking of Pokémon, why don't we get you set up with another starter Pokémon?"

"Yes, I do believe it is." Ash responds.

The Professor then steps aside, and reveals three Pokéballs on the table.

"These are the three Kalosian starter Pokémon; the Fire-type Fox Pokémon Fennekin, the Grass-Type Spiny Nut Pokémon Chespin, and the Water-Type Bubble Frog Pokémon Froakie."

Ash thinks for a while, and after looking at all three Pokémon, something nagged at the back of his mind.

Suddenly, he felt nauseous, and grabbed onto the table.

The professor's face went from a patient look to one of worry. "Ash, are you alright?"

Ash takes a few deep breaths. "Prof…" He takes a few more. "I'm not…"

And that's all he can muster before he blacks out completely.


Ash wakes up to a black void, with a feeling in the pit of his stomach similar to that of someone free-falling, yet he felt no rush of the wind past his ears.

He looks down, and he sees a platform of some kind. He feels as if he's moving at a thousand miles an hour, yet the platform he's falling towards makes it look like he's slowly floating down, at around 5 miles per hour.

Then, he touches the platform with his feet, and he sees the three Pokémon standing before him. Then, they immediately evolve into their final forms, yet with slight alterations.

Greninja was in his usual ninja stance, except he was holding a sword made of three different materials. One side of the sword was made of a material that glowed a bright white, the other side was a dark purplish-black material, and instead of a normal cross-guard and handle, it was two razor-sharp spiked pointing outward, and a third going down the handle that the Ninja Pokémon was holding, as if he were combining the moves Cut, Night Slash, and Water Shuriken into one sword.

Delphox was in her usual stance, looking slightly to the left with a smile on her face, and a huge, yellow tail with a red 'dress' made of her fur covering her midsection and feet. Except instead of a stick or a branch in her hand, she had a staff made of a wood-like material that had a pointed bottom section, and two branches forming out of the one for the top foot and a half, which then split into four smaller roots that held in place a perfectly cylindrical Fire Stone.

Chesnaught was standing tall and proud with his fists ready to strike, and he smiled in a bloodthirsty-like way that made you think that he was born for battling, and that he knows nothing else. He was his usual white and green body, but instead of a cream-colored shell, it was a blackish color that reminded Ash of obsidian, and the spikes on both his shell and his arms, as well as his claws, were pure diamond. Guess that explains why he had that smile; he thought he was indestructible.

Suddenly, a powerful being appeared. It was a huge, white being with a blue scarf, and a body that reminded him of an enemy that he used to read in a book when he was younger. It had a strange symbol on his forehead as well; a four-sided throwing star with an upside-down heart as the bottom piece.

The three of them turned around to face this being of great power, and got in their battle stances.

The being looked at them, and then at Ash.

No, not looked. He glared at him.

And Ash knew that he was coming for him.

The three Pokémon noticed this, and as the white being reached out to a petrified Ash, the three Pokémon leaped into action.

Delphox started chanting a spell, Chesnaught positioned himself between the being and Delphox, and the Greninja leapt at the being in an attempt to keep it distracted.

However, before any of the Pokémon could do anything, the huge being unleashed a flash of bright light that blinded the four. Once they could see again, Ash saw the three Pokémon held in the air, their hands and feet stuck to four balls of whitish-lavender orbs, unable to do anything. The huge being then closed it's hand, reeled back, and struck each one of them, earning cries of pain.

As they were struck, the orbs holding them in place seemed to have disappeared, sending them flying backwards and into the void.

However, just before they could get too far, the being then stretched out it's arms long enough and fast enough to grab all three of them, instantly halting them and giving them whiplash, and bringing them back to the platform and the great being. It then threw them up in the air, causing all three of them to give cries of fear as they were thrown upwards at incredible speeds. Noticing how high she was getting, the Delphox pressed its dress between her legs to keep Ash from seeing under it. On their way down, the being looked like it was ready to throw something. As the Pokémon were on their way down, the being then swung it's arm down, both hitting the three Pokémon and increasing their speed, damaging them from both the impact with the being's hand and the platform itself, causing the platform itself to crack around them.

Ash looked at the three Pokémon on the ground. Chesnaught's shell had cracks in it, the diamond spikes cracked and broken in several places. Delphox's dress was in tatters, her staff snapped in two and the fire stone shattered in multiple pieces. Greninja's sword was broken in the three pieces, and those pieces further broken into shards of their former forms.

Ash looked upon all of them with hopelessness. If these three Pokémon, who were at their final evolutions, couldn't stop the great being in front of them, then what hope did he, a normal human being, have?

Suddenly, a bright light shone on Ash, causing the great being to shield its eyes and back up, causing it to trip over itself and fall over the edge of the platform.

Then, a majestic woman's voice spoke to Ash from the source of the light, which was too bright for him to see, saying "If you had the power to save these Pokémon… would you?" the being asked. Before Ash could respond, the voice also said "Think before you speak, for your answer may induce actions whose consequences you may not like."

And without a moment's hesitation, Ash said "Yes, I would. Helping others is what I do on a daily basis. I would give my life if it meant someone else would live."

"What are you called, child?" The mystical voice asked.

"My name is Ash Ketchum, Champion of the Orange Island League, first victor of the Battle Frontier, and Aura Knight-in-training."

"Ash Ketchum…" the voice repeated. "Sounds like an appropriate name. However, I think 'Chosen-One' has a better title than the others."

Ash kept looking up at the bright light as he said this, and an object starts floating down from the light source. As it gets closer, he can start to make out what it is. It gets within reach, and he can make out a black and grey device with gold trimming similar to the Unova Pokédex, yet instead of the bottom half being just the grey casing, it has a multicolored tri-symbol logo. The top right third of the symbol was green, with the logo in that third being the mega-evolution symbol he'd come to know through his brief time studying the Kalos Region during the plane ride, yet the other two symbols were completely new to him.

The top left third of the symbol was blue, with the logo being similar to the one on the forehead of the creature that the pokemon have been fighting. The bottom third is red with a symbol that looks somewhat like a face. In the middle of all three thirds, a purple trifecta seems to keep them separate from each other, yet also keeps them connected to one another.

The mystical voice then said "Use this Fusion Loader wisely, Chosen-One."

Ash reaches out to grab it, yet before he does, he asks "What does this… 'Fusion Loader' do?"

The voice goes quiet, then the female voice says "See for yourself."

The voice goes quiet, and just as Ash grabs the Fusion Loader, the light disappears, and the laws of physics applies to the device in his hand.

There's three buttons on the device; a red one with the red face portion of the symbol on the front of the device, a blue button in the shape of the symbol on the white being that feared the light, and a Pokéball button. Pressing the third button, the device pops open, scans the three Pokémon, and deposits this information:

Delphox, the Fox Pokemon. Using pyrokinesis, it generates a fiery vortex of more than 2900 degrees Celsius, incinerating foes swept into this whirl of flames. It can also gaze into the flames started by it's Flame Staff to achieve a focused state, which allows it to see into the future. This Delphox is female, and has the ability 'Magician', which allows this Pokémon to steal an item from an enemy that it hits with an attack.

Greninja, the Ninja Pokémon. It appears and vanishes with a ninja's grace. It toys with it's enemies using swift movements, while slicing them with throwing stars it creates from compressed water. Thrown at a high enough speed, these stars can split metal. This Greninja is male and has the ability 'Protean', which allows it to change it's typing to the move it last used.

Chesnaught, the Spiny Armor Pokémon. It's tackle is forceful enough to flip a 50-ton tank. When it takes a defensive posture with it's fists guarding its face, if can both withstand a bomb blast, and shield others from the same blast.

Recommendation: recall the Delphox and Chesnaught, and summon your Serperior and Typhlosion in order to Poke-fuse them into a new being with greater power than all three of them separate."

Ash thinks about this for a moment, and before Ash could do anything, the device says "If you agree with my recommendation, then press the third button twice, and I'll take care of the rest. Of course, that is if you have a better idea."

Ash almost dropped the device after finding out that it could talk on it's own.

"Look, we can talk all you'd like when we're out of this situation. But right now, I need you to trust me. Once they get here, press the red button that looks like a face. It'll combine them into a being of Legendary power. In case of emergencies, press the blue button."

Still skeptical, he pressed the Pokéball button, and both the Delphox and the Chesnaught turned into red and green beams of energy respectively, and were absorbed into the Loader, only for the Loader to spit out two more beams to where the two Pokémon were, one green while the other red. Both Snivy and Quilava appeared in a flash, then they turned into blobs of energy with their respective colors, and then grew in size and shape until the energies turned into their final forms of Serperior and Typhlosion respectively.

Once they were open, Ash pressed the red button, and the device's second screen appears, and both screens light up. The top screen has four crystals while the second, lower screen has a Pokéball. Off the sides of the second screen, two miniature radio antennas appear while a third one appears from the top section of the second screen towards the right corner, and all three Pokémon were turned into their respective colors of energy and absorbed into the fusion loader.

Once their energy was done loading, three of the crystals lit up in different colors, and shattered to reveal the Pokémon. The fourth crystal disappeared, and then all three images were transferred to the Pokéball on the bottom screen, which turned into an actual Pokéball that appeared in Ash's hand that wasn't holding the Fusion Loader.

The Pokéball itself was pretty much emanating with power. Suddenly, images of the Pokémon began to appear in his mind, along with a name.

Just then, the white being from before appeared in a flash of movement. And in that moment, Ash knew what to do.

He threw the Pokéball, and said "Appear, Tyserninja!"

A golden light appeared from the Pokéball, and radiated around the area that Greninja was in, and then it disappeared to reveal a magnificent being.

It was a slimmer Typhlosion with white fur on its underside, frog-like legs that were green on the upper thigh with white bulbs on the sides, gold skin for the lower half of the legs, and white feet with golden webbing. It also had a tail like Mewtwo's, except it was white on the bottom half and green on the top with a 3-inch gold ring about a foot from the base of the tail. On its chest was a piece of Serperior's body, and it had arms that were the reverse of its legs, with golden, frog-like skin for the upper arms and green skin from the elbow to the wrist with white bulbs on the arms, and three-clawed paw-like hands. There were also several places around the body that was spewing out fire; where the green and black of the chest met the black and white of the neck, the elbows, the tip of the tail, and opposite sides of the tail 6-inches from the tip of the tail where the green fur meets the white.

This new being, now known as Tyserninja, roared with such a power that would rival that of the Legendary Pokémon Rayquaza.

The great white being just stood there, either unimpressed or uncaring. Then, a flash of white blinded everyone again, and when Ash found his sight again, he saw the same situation that the three Kalos starters were in before; the Pokémon was suspended fifteen feet above the platform, spread-eagle.

Out of mild curiosity, Ash looked at the back of the Loader, and found a camera on the device. Pointing at the great being, the Loader scanned the being, and spewed out some information.

"Twilight Thorn, a Giant Nobody with multiple thorns and strong fists. It has the ability to dodge many enemy attacks and to summon Creeper Nobodies to his side and to create a huge ball of energy, which he uses to throw at his enemies."

After the Loader said this, the being, now known as Twilight Thorn, took a closer look at the new being in front of him, then reeled back his fist in an attempt to punch Tyserninja just like he did the other three Pokémon.

But what Thorn didn't expect was the fact that that Tyserninja swiveled its body around his left arm, keeping that one orb from moving, and somehow managed to hit the fist coming at him with an even greater strength than Thorn anticipated. This caused thorn to spiral backwards into the void behind him about thirty feet away from the platform before he stopped moving and regained his balance.

He then extended both his hands towards Tyserninja, and dispersed the orbs holding him in place by grabbing him, and threw him into the air.

Doing the same as before, Thorn prepared to slam Tyserninja into the ground on his way down, but yet again, he wasn't prepared for Tyserninja's counterattack.

Tyserninja started gathering energy into his fist as he reached his highest point from the throw, and just before Thorn could impact him, he summoned a giant elemental fist that was part fire, part water, and part solar energy, which Tyserninja used to pummel Thorn into the ground just before altering his body's angle to land on it's feet, which cracked the platform even further and caused no damage to Tyserninja himself.

The Thorn fell face first into the platform at the opposite end of the platform from Ash, and then he fell off the platform itself.

Thinking that it was over, he sat down and brought out the Fusion Drive. I was about to press the red button again, but Tyserninja growled, and started to look around as if he were confused.

Ash looked at him confused, then brought up the Fusion Drive and said "Twilight Thorn."

The information he learned earlier pulled up, and as he was reading through it, one section of the information confused him slightly.

'…creates a huge ball of energy…'

'wonder how long it takes to charge up an attack that sounds that powerful.'

Unfortunately, he was about to find out. As soon as he thought that, the platform tilted rather quickly, causing Ash to tumble down the far end of the platform.

Just before he fell over the edge, Tyserninja punched his arm into the platform with one arm, and caught Ash's left arm with his other arm. Once they stopped sliding down the platform, which was just inches away from the edge, Tyserninja roared in anger. He looked over, and the Thorn was on the other side of the column that the platform we were battling on was on, along with a huge ball of energy bigger than he was. He cocked it back, prepared to throw it, and probably kill Ash and his new Pokémon.

Ash looked down at the fusion loader, and he figured that this was more of an emergency than anything.

Ash pushed the blue button.

It was surrounded by a mystical white light for a split second, and then it elongated to about four feet long before the light was absorbed into what was being created, and then Ash found himself holding a four-foot-long blade that looked a little bit like a fusion between a blade, a key, and a pokemon he'd only seen a couple times before.

The weapon he was holding was mainly white with a golden circle about seven inches in diameter with two golden parenthesis on either side connected by four golden spikes, and where the spikes met the parenthesis, four jewels were fused into the gold; one green emerald, one red ruby, one blue sapphire, and one yellow amethyst. The "blade" itself reminded him of the Legendary Pokémon Arceus, with a gray patch of metal about six inches long three inches from the handle, and half of the crossguard symbol on the end to make it look somewhat like a key as well as a sword, except it's got another spike protruding from inside half of the golden circle, and crossing over Arceus' forehead. And even though he's seen Arceus before and she never had one, her muzzle was golden on the blade.

As he was holding the blade, he was filled with confidence. His mind sharpened, his eyes focused, and one seemed to slow down a little as he analyzed his surroundings. Tyserninja noticed this, smiled, and started swinging Ash back and forth a little. Ash noticed this, caught on to his plan, and he swung himself forward as the Twilight Thorn threw the giant orb of energy at Ash.

Pulling back his arm, he used his own momentum to throw his keyblade at the orb with even more force than him swinging at it could, which caused the orb to explode with energy, knocking Ash back with a little bit of force, and throwing the Twilight Thorn into the void.

Somehow, as they were falling further down into the void, they hit another platform that looked exactly like the one they were fighting on. Both Ash and the Twilight Thorn hit the platform on their back, and a few seconds later, Tyserninja landed on the platform on his feet and helped Ash up to his own. Looking at the Twilight Thorn, it steadily got to his own feet, and turned around to face them.

Suddenly, Tyserninja started glowing white, and was enveloped in a white light, being absorbed into the Amethyst of the blade Ash was holding, and the energy was transferred to the Ruby, Sapphire and Emerald, which was then shot out of said jewels, and formed Greninja, Serperior and Typhlosion. Once the three formed, the keyblade disappeared, and on Ash's right wrist was a small chain with three metallic symbols on it; one in the shape of a blue heart, another in the shape of a red face similar to the one on the logo, and the third one being a pokeball.

The Twilight Thorn then started stumbling around in place like a drunk person would, and then it started to dissipate into black orbs as it fell over, completely dissipating before it hit the quadet.

However, once it completely dissipated, a dome of bluish-black energy formed around the platform. Then the energy started to slowly creep towards the center, trapping the four.

Typhlosion threw a flamethrower at the dark barrier, however it did no damage, the flames turning into black as soon as it touched the barrier, and travelled up the flamethrower like a flame to a hose shooting gasoline. As soon as the black energy touched Typhlosion, the pokemon froze in place, the black energy beginning to surround the pokemon. Once it was engulfed in energy, it turned into that same energy.

The remaining three were surprised, and started backing away from the darkness, Greninja staying close to Ash while Serperior was trying to bat away the darkness with a couple Vine Whips.

Unfortunately, the darkness clung on to one of the vines as it was being withdrawn, which started crawling it's way further up the vine like a virus of some kind, turning the Unovan Grass starter into more black energy.

Ash and Greninja were back to back in the middle of the platform, the darkness closing in on them from all sides.

Ash clenched his fists. He started to get angry. Angry that after all he did, after finding out he could do all these things, after creating something that nobody's ever seen before in a way that nobody even knew about, that he would be defeated. And just as he was about to come up with a couple more ideas, his only weapon to help defend himself disappeared on him.

He turned around to look at Greninja, and Greninja turned around to look at Ash. And Ash saw something in Greninja that he didn't expect at this point.

Defiance.

As if Greninja refused to believe that this was his last moment.

And then it started to grow in Ash, turning his thoughts from anger to courage.

Greninja refused to believe that this was the end. There's no reason why he should.

Then, a blue fireball ignited and floated between the two, and the darkness stopped it's advance. Ash looked around at the darkness that stopped, then back at Greninja, it's own confidence building up Ash's.

Ash smiled, and so did Greninja.

"Greninja… I choose you." Ash said, holding up his hand to one side of the flame.

The pokemon smiled, and brought up it's webbed hand to the other side.

Then, as one, they brought their hands towards each other, touching the blue flame and grasping each other's arm in their grasp, causing the blue fire to explode around them, destroying the darkness and turning their vision white at the same time.


Suddenly, Ash opened his eyes, and found himself in a room he didn't remember entering, lying in a bed he didn't own, with an IV in his arm connected to a heartbeat monitor next to the bed.

It was a simple room, a queen-sized bed, a desk next to a window, and a set of double doors about five feet away from the bed.

He looked down to the foot of the bed, and saw his little Pikachu sleeping peacefully.

He smiled at the sleeping pokemon, a blissful look on his face. He decided to see if he could get a couple more hours of sleep after that.

The next morning, he was leaving the Professor's lab out the front door after explaining everything to the Professor. Unfortunately, he couldn't make the device or the key-blade-thing reappear, so he didn't really have any proof of what he said. However, the professor believed him anyway. In his own words, all our dreams always have a shed of truth in them. However, i think he meant that the shed of truth wasn't the device, the key-blade, or the poke-fusion, but was me choosing Froakie as his starter pokemon.

Go figure.

Ash took a deep breath, and started walking towards the Lumiose City Pokemon Center to have him registered to the Kalos Gym Challenge and Kalos League, then off to the Lumiose City Gym to challenge the Gym Leader there.

He brought out the Kalos Water-Type starter pokemon, Froakie. He appeared with a smile in his face, and had a courageous look about him… no, not courage. Hope? No, it didn't look like that either.

That's when it hit him.

Defiance.

He saw a similar look in that Greninja that he was battling with.

Confused, he recalled his Froakie, and started walking down the streets to the Pokecenter, thinking that it was all a big coincidence, and that his vision was nothing more than a dream.

However, he failed to realize that he still had the chain on his wrist with the three keychains on it.


Further down the street behind Ash was a girl with a similar chain on her left wrist. She was wearing a black v-neck shirt, a red skirt, black leggings, black sneakers, a pink hat with a stripe of black cloth around the brim, and a pink purse on her right shoulder, a single pokeball on her skirt belt. Her blonde hair was covering half of her face, yet one of her piercing blue eyes were following a strange man that she doesn't recognize with a name that she can't seem to forget.

"I can't believe, that after all these years… I finally found him…"


So how was it? Reviews would be awesome, be they good or bad.

Stay dangerous, Lunar Knights!
