DISCLAIMER: Square Enix and Disney own Final Fantasy and Kingdom Hearts respectively. Blizzard Entertainment owns Overwatch.

Okay, so this MAY NOT be what you would be expecting or anything, but I began to love the upcoming game Overwatch as much as I enjoyed the game Kingdom Hearts. And since they were stuck in my thoughts, I decided to make a story that included their memorable characters. I personally thought "why not imagine a crossover between Kingdom Hearts characters and the colorful Overwatch heroes?", so that's basically what I did with this story.

Also, if possible, please leave a review. I want to know what you guys think of this story afterwards. Constructive criticism, regarding grammar and other important writing features, would be nice too. Thanks and enjoy.

A New Light of Heroes

Prologue

A man had leapt into the pool of blackness, and behind him was a powerful army of colorful oddities.

Overwatch. These strange yet extraordinary people all shared the common inability to show even a speckle of fear in their eyes, as they instead had mixed expressions of hope, courage, determination, and harmony.

Every last one of these brave warriors had undergone a common process that would allow them to make use of the power of Light in order to fend off the threatening forces of Darkness.

Many men, women, and even a gorilla were ready to risk their lives and fight an oncoming force of doom in the name of both peace and justice. Many of them ranged from wielding strange firearms, to largely improbable melee weapons.

The man leading everyone into the fray had carried a large rifle in his hands. He had short blond hair and blue eyes, one of them covered by a blue scouter. Over him was a blue trench coat fitted with blue shoulder pads and gauntlets over the sleeves. Underneath was a blue chest plate, followed by a pair of black pants fitted inside two metal combat boots.

Strike Commander Jack Morrison was ready for what was coming to him and his army-like team. He was confident enough that everyone would make it out alive after this battle was over. He believed this because with him was not just an army, but a whole family completely willing to always be at his side no matter what.

Morrison and his extraordinary army gracefully landed into the middle of the black swirl of dark monsters. One half opened fire and sprayed colorful projectiles onto the creatures, while the other half rushed in and slayed them with swords, hammers, etc.

The gunners ran and leaped around as they shot down numerous monsters. Not one single thing was able to touch them. The warriors, on the other hand, went up close and personal as they swung and vanquished much more monsters than their gun-wielding comrades.

Several of them happened to be carrying around key-shaped swords. One of those key-wielding warriors also happened to be a small mouse with big round ears. There were two more men, one of them having darkish purple hair tied into a ponytail while the other one was bald and had yellow eyes and a small white beard.

Members of Overwatch instantly cleared about a radius of two feet between themselves and those dark monsters.

Heartless. That's what everyone and everything called them. Monstrous beings that spawn from the Darkness and also the lack of people's Hearts. They hunt down anything that contains a Heart, due to the lingering Darkness that lies dormant in each and every one of them.

Blackened skies and dark fumes were currently surrounding the heroes and the Heartless. The sandy shores of beaches were being crushed down upon by the strong tidal waves. The buildings were crumbled and trees were cut into pieces.

This was what was left of the so-called Destiny Islands.

Luckily, everyone who lived here was safely evacuated before the Heartless could wreck any more havoc around him or her.

As Jack Morrison shot down many more Heartless in the area, another one lurked behind him as an attempt for a quick and easy takedown. The creature leapt towards the Strike Commander…

BANG!

A blue line instantly pierced through the Heartless, evaporating into dark fumes. Morrison quickly turned around to see the source of the gunshot.

The shooting man pulled back his silver revolver. He carried a cowboy theme with his outfit. He wore a brown wide-brimmed hat that covered his brown unkempt hair. He had a messy-looking beard across his jaw, along with a tobacco sticking out of his mouth. He wore a brown shirt underneath a metal chest plate. A red poncho draped over his shoulders and hid his metallic, prosthetic left arm. He also had brown pants and boots with spurs attached to the back.

"McCree." Jack Morrison acknowledged.

McCree chuckled as he shot several more Heartless. "Can't be too careless now, Morrison. You don't wanna die just yet, do ya?" He said with a Western accent.

Morrison smirked and nodded at McCree, who tipped his hat to him in response. They returned to the fray right after.

The key-wielding mouse jumped into the air right before swinging down his golden weapon onto the Heartless. Numerous Heartless were slain right after the landing.

The mouse wore a short-sleeved jacket with white lining. The top half of his jacket was black, while the bottom half was red. There were also two yellow straps dangling in front of his jacket. He wore red pants, which sported a zipper that went down the front of each leg. Each leg had a yellow pouch with a black strap, along with a blue strap on the outer side of each pant leg. He also wore very large, yellow shoes with grey backs and two orange, intersecting straps attached to the front of each shoe.

Many more Heartless rushed at the mouse, but he immediately notices them and slashes them down with his weapon.

Nearby the mouse was a ninja-like cyborg. His body looked almost entirely robotic as he was covered in white plated armor and tannish muscle fibers. He wore a silver helmet with a slit green visor, along with a long grayish cloth tied to the back of his head.

"RYUUGEKIKEN!"

The ninja quickly pulled out a green-edged katana from his back and twirled it around; his metal armor shifted easily as if it was his own body. Briefly following the unsheathed blade was a green dragon made of spiritual energy. As the cyborg held his blade with a firm grip, the dragon roared before dissipating into green particles of light.

"The dragon and I are one!" The cyborg ninja shouted in a thick accent.

With a strong battle roar, the cyborg ninja rushed in and cut down the groups of Heartless that stood in his way. He swung his katana left to right, up and down until his foes were vanquished into black smoke. He made sure that every one of those dark monsters had tasted the deadly edge of his Dragonblade.

Running past the cyborg ninja was a large man wearing silver bulky knight-like armor. Every piece of the crusader's armor was abnormally huge, from the shoulder pads to the armored gloves and boots. There was even a small rocket engine on his back. On his head was a helmet with a yellow visor on the front to allow proper vision.

In his large hands was a rocket-propelled hammer that was ready to smash its foes. The crusader largely swung his hammer across the sides, hitting and smashing at the groups of Heartless that dared to stand in his way. After two more horizontal swings, he pulled his hammer above his head.

"HAMMER DOWN!" The crusader smashed his weapon into the ground.

The force of the smash allowed the crusader to create a powerful shockwave that blew away a wave of Heartless in his path. He lifted his hammer and twirled around before letting it rest in his hands again.

The crusader let out a hearty laugh. "I'M THE ULTIMATE CRUSHING MACHINE!" He screamed valiantly with a thick accent, as he ran towards more of his Heartless foes.

Spotting a larger Heartless ahead of him, the large crusader activated his back rocket and launched himself to the impending foe.

Meanwhile, rocketing into the air was a duo consisting of a gorilla and a woman.

The gorilla was wearing a black bodysuit covered by white metallic armor. Over his eyes was a pair of glasses.

The woman rocketing up with him wore a blue, bulky rocket-propelled suit. Covering her head was a helmet shaped like a bird's beak.

The blue-armored woman pulled her arms back as she unleashed a barrage of missiles at numerous Heartless.

"JUSTICE RAINS FROM ABOVE!" The woman shouted.

The gorilla, on the other hand, smashed every single Heartless that fought him. He swung his arms around in order to smash and hit his shadowed foes.

Jack Morrison continuously opened fire against the forces of Darkness before eventually launching a set of missiles onto a small group of Heartless.

The mouse leaped by Morrison's side as he swung and struck down many more oncoming Heartless. He had barely yet to reach to a point where he would be exhausted.

"…Help…!"

Morrison flinched. A civilian? Still within the area? He quickly looked around, making sure that he wasn't losing his mind already.

"…Somebody…Help…!" The voice called out again.

Morrison heard more clearly. It sounded like a child. He quickly turned his head to his right, seeing a somewhat destroyed building. That may be where the voice is coming from.

"Mickey!" Morrison called out.

Hearing his name, the brave King Mickey Mouse turned his attention to his friend, Morrison, who had a somewhat worried look on his face.

"Jack?!" King Mickey responded.

Morrison started shooting at the extended lines Heartless in front of him. "I need you to hold the team together! I'm going to head over to one of those buildings down by the beach!"

He was confident enough to be capable of going on his own, while the rest of his teammates were able to fend off the swarming Heartless in the huge area. He knew his own team very well, and he highly doubted that any of them was going to fall to any of these horrid creatures.

King Mickey, however, surprisingly widened his eyes after swinging his key at several more of the leaping Heartless.

"What?! Why?!" King Mickey yelled.

In an instant, Morrison sprinted down his forged path while shouting, "Just keep everyone alive! I'll be back!"

King Mickey could only do as he was told as he stood alongside the rest of his teammates. He swore to himself that no one was going to fall on his watch. Besides, they had a medic that was capable of reviving the near-dead.

The Strike Commander sprinted his way across the sandy shores while spraying blue bullets at every single Heartless that jumped at him. Each and every one of his foes dissipated into blackish fumes, which Morrison also ran through.

Morrison paid no mind to the Heartless that stood beside him as he continuously sprinted his way down to the nearly destroyed building.

One larger Heartless suddenly stood in Morrison's path, but he quickly unleashed a spiraling barrage of three small missiles directed at the bigger beast. The swirling projectile successfully made contact with the Heartless and it was blasted into more fumes like the rest of them.

"Help!" The young voice shouted again.

Morrison heard it getting louder and turned his attention to the oncoming building to his right. He tilted his running direction towards there.

He was getting closer to the source of the voice. However, more Heartless stood in his way. They seemed so keen on killing him, but it never works out well for them. Refusing to stop moving, Morrison quickly reloaded on ammunition and then tapped onto his scouter eyepiece, causing it to open up a large holographic rectangle in front of his face.

On his holographic visor, all present Heartless were covered in crosshairs. "I got you in my sights!" Morrison shouted.

As if he was controlled by an aimbot, the Morrison aimed his rifle at every single Heartless in the vicinity with perfect accuracy. Every single bullet managed to tear them into nothing but fumes and pieces. Morrison continued to charge forward as he riddled his enemies with his blue bullets. Every last one of the Heartless continued to vaporize into thin air as they were utterly destroyed by the lone Strike Commander.

He finally made his way to the source of the voice. In front of his vision was a damaged house, slowly crumbling apart, bit by bit. Having no time to lose, Morrison rushed his way to the broken building. He didn't want to come all this way for nothing.

Kicking the front door open, Morrison quickly walked inside with his pulse rifle aiming forward. He checked his front and then both sides, before closing the door shut. He carefully eyed around the vicinity, checking for any enemies from any direction. Lucky for him, there were none, for now.

A dim ray of light suddenly shined down from a cracked hole on the ceiling, giving Morrison a clearer view of the surrounding environment. All there was were just torn up furniture, broken glass picture frames, and piles of stone torn from the ceiling.

Morrison lowered his rifle and stepped forward.

"Hello?!" He called. "Anybody here?!"

The Strike Commander walked more slowly and more carefully, as the silence had started to creep up on him. Strange though, he could've sworn that someone was calling for help. Was he wrong? Was it just some sort of delusion?

Morrison cautiously eyed around the current room once more. He walked further and further with his rifle still being held in his hands.

He shouted, "Hello?!"

No... it couldn't be, could it? Then again, wasn't he the only one who even acknowledged that cry for help? He needed to know.

Morrison took one more step forward...

CRACK!

Startled, he quickly pointed his gun downward, but calms down as he realizes that his foot was on a picture frame. The glass was already shattered and he couldn't see the photo under his foot. Morrison pulled it back and knelt down to get a closer look.

When Morrison examined the picture, he noticed that it showed a small family, consisting of a mother, a father, and a little spiky-haired boy who happened to be the son. To him, they looked really happy together. Their arms were wrapped around one another and all of them had expressions filled with joy and laughter. They looked as if they would never leave each other for anything else.

Where were they now though?

Jack Morrison stood up and turned his head side to side. He checked to see if that happy family was still present somewhere. All he could see, however, were torn fabrics of clothing, and ruined necklaces and other accessories. There were also scratch marks, which he didn't even notice until now, all over the floor, walls, and ceilings. The walls had small dents onto them as well. It looked like there was some sort of struggle.

To his shock, unfortunately, Morrison's eyes caught the sight of several suitcases currently filled with personal belongings and articles of clothing. The owners of this house hadn't left at all, it seemed like. The Heartless might've had broke into their house and ambushed them. The only outcome he could imagine right now, was death.

Morrison could only close his eyes and let out a heavy, heartbreaking sigh.

He had actually believed that everyone had safely evacuated out of the Islands. And he even believed that everyone was going to make it out alive of this place. Was he wrong about that? He didn't want to think about the answer. Perhaps that desperate cry was just a delusion after all...

"Hello…? Anybody…?"

He could still hear the voice in his head, echoing in fear. Maybe that was just his emotions playing with him.

"Is anyone out there? Can you answer me, please?"

The voice was already starting to get louder and louder. It was almost too real for Morrison. Almost.

"I need some help! Can someone hear me?!"

Wait. That voice IS real!

Jack Morrison surprisingly opened his eyes. He quickly turned his head side to side, desperately searching for the voice again. He then spun around in search of the young voice.

"Yeah! Hello?! Where are you?!" Morrison called out.

"Under here…!"

Morrison turned around behind him. There was a pile of stones by the end of the room. There was a large space that was enough to fit in a small person. Speaking of a small person, there was actually a young boy who was lying safely under those stones.

He looked like he was about seven years old.

The boy's head stuck out, showing his blue eyes and somewhat spiky brown hair. He had a mixed expression of concern and fear as he looked up at a kneeling Morrison. Morrison sighed with relief as he was grateful that at least one person was still alive.

The Strike Commander slowly placed his rifle on the ground as he looked at the boy worriedly.

"You okay?" Morrison asked.

The boy nodded hesitantly. "Yeah…"

Morrison got a better look at the boy. It didn't look like he was hurt or anything that was considered to be worse than that.

He gave a quizzical look. "What're you doing under there, kid?" Morrison asked.

"…Hiding. From the monsters." The boy answered.

Morrison could see the fear and sadness that lingered in the boy's eyes. They looked like they just saw death not too long ago. They looked like the kind of eyes that wanted to forget everything that they just saw. The kind of eyes that would receive a form of pity by someone else.

Morrison nodded slowly. "Oh…" He responded.

The boy looked at the ground. "You're not one of them, are you?" He asked. "You're not one of those monsters?"

Morrison shook his head politely. "No. Course not, kid. I'm one of the good guys. You've heard of Overwatch?"

The boy's eyes widened and he nodded his head. Morrison only smiled.

"Well, I'm here to save you."

The boy looked back at the older man. He had a new expression consisting of surprise. Morrison could already see the boy's eyes glimmer with hope and slight happiness. It was already safe to say that he was going to be all right.

"Really?" The boy asked hopefully.

Morrison nodded and smiled. "Yeah. You can call me Jack, if you want." He offered.

The boy started to smile and nodded back. "Okay. You can call me Sora, if you want." He repeated to Jack Morrison.

The Strike Commander let out a small chuckle. "Okay, Sora." Morrison grabbed his rifle. "I think it's time I got you out of here. Don't you think so?"

Morrison extended his left hand to Sora, who slowly reached for it and smiled.

"Okay!" Sora replied.

Morrison smiled. "Okay."

Perhaps Lady Luck hadn't abandoned everyone after all.

Sora safely got out of the rubble and stood up beside the tall soldier. Morrison hefted his rifle over his shoulder as he readied himself for any more threats that came in his and Sora's way.

They walked to the door and Morrison kicked it open. To their surprise, however, no Heartless were present around the area. To Morrison, it was actually relieving. He then looked and smiled at Sora.

"Guess the coast is clear." Morrison said.

Sora only chuckled as he continued to hold the soldier's hand. They calmly walked their way to the rest of Morrison's team. Sora was going to meet the team that made up Overwatch, the colorful peacekeeping force.

Back to the rest of the team, King Mickey watched as the rest of the fallen Heartless faded away into more black fumes. Half of the warriors placed their firearms back into their holsters. The others either sheathed their melee weapons or just rested them over their shoulders.

Hearing the footsteps of two people, everyone turned their attention to the oncoming people.

The team of Overwatch looked as Morrison and Sora walked towards them. Coincidentally, a bright ray of light pierced through the dark sky and shined down on the entire team, including Morrison.

King Mickey was shocked to see Morrison bringing a young kid with him since he did not expect any more civilians to remain at the Islands after the evacuation. Within the crowd of warriors, one suspicious-looking old man looked and smirked at both Morrison and Sora.

A surprised Sora looked up at Morrison. "Are these people good guys like you?" He asked.

Morrison nodded kindly. "Yes, Sora. They're just like me. They're good people. People who are willing risk their lives to do what is right. People who are able to protect those they love and care about. Some just call us a team of heroes, but…we're more than that." He pointed out. "We're also a family."

"Oh…" Sora shyly looked at his feet. "So, do you think…that I could be a part of this family too?"

Morrison chuckled. "Of course. You're already a part of it."

Sora quickly looked back up at Morrison with a very happy expression. Morrison patted Sora on the head.

"From now on, you'll be under my care. You all right with that?" Morrison asked.

Smiling immediately, Sora nodded excitedly.

"Yeah!"

Heads up, backstory of Overwatch and its characters WILL BE SLIGHTLY DIFFERENT/TWEAKED from the original versions. Just saying.
