Well... this is it. To quote Cartman from South Park... Civil War's going down! I don't own Kingdom Hearts nor the Avengers.

In the year of 1991, at the HYDRA Siberian Facility in Siberia, of the Soviet Union, where a group of HYDRA operatives, inside the Soviet, soon to be Russian, Armed Forces does their operations there, Russian Colonel and HYDRA operative Vasily Karpov types in a code before a small door opens to reveal a red book with a black star on the cover. He then revived a person from a cryostasis chamber. The person is known as James Buchanan 'Bucky' Barnes, a former soldier of the US Army and the childhood best friend of the war hero known as Captain America. Unfortunately, he was thought to be killed during a fight on a HYDRA train back during the war. In reality, he actually survived, albeit with the loss of his left arm. Brainwashed and armed with a new cybernetic limb, Barnes ultimately became an enhanced HYDRA operative known as the Winter Soldier. Over the next several decades, he would eliminate anyone who posed a threat to HYDRA. Anyway, Karpov has revived Bucky and, along with other HYDRA operatives and scientists, subsequently put him under the Memory Suppressing Machine to wipe his memories and emotions. During Bucky's brainwashing session, Karpov is reading the red book to trigger and activate the Winter Soldier.

"Longing. Rusted. Seventeen. Daybreak. Furnace. Nine. Benign. Homecoming. One. Freight car." He read in russian.

There was only silence as Bucky looks at Karpov closing the book and sets it at a nearby table.

"Good morning solider." Karpov greeted.

"Ready to comply." The winter solider said.

Bucky arrived back at the HYDRA Siberian Facility with the briefcase to deliver to Karpov. Bucky then opens the case. The case shows five blue packets of the Super Solider Serum, the same serum that created Captain America. Karpov is impressed with Bucky's mission success.

"Well done, solider." Karpov said.

However, this event was only the beginning.

In the present year of 2016 at a local café at Lagos, Nigeria, Sora and Kairi meet a woman was adding sugar to her coffee while wearing shades and a baseball cap. The woman's name is Wanda Maximoff, but she is better known as the Scarlet Witch and a member of the superhero team known as the Avengers. They are currently on a mission to find an old enemy of Cap, Natasha, Sora and Kairi.

"You know, I wish your suit wasn't faulty right now. Kairi." Sora said while taking a drink of his coffee.

"We'll worry about it later, Sora. Right now we gotta find Rumlow and stop whatever he is planning." Kairi whispered. Sora nodded then he turns to his commlink to listen to his friend Captain America.

"All right, Sora. What do you all see?"

They looked around. Standard beat cops. Small station. Quiet street. It's a good target." Wanda said as she surveys two police officers and the street.

Cap, who is positioned inside a building, looks out the window seeing the street as well.

"There's an ATM on the south corner, which means?" Cap said.

"Cameras." Wanda replied.

"Both cross streets are one-way." Cap said through the comlink.

"So, compromised escape routes." Kairi said.

"Means our guy doesn't care about being seen. He isn't afraid to make a mess on the way out. You see that Range Rover halfway up the block?" Cap asked.

"Yeah, the red one? It's cute." Wanda said.

"I prefer blue." Kairi stated.

"Focused Kairi." Seethed Natasha. "Its also bulletproof, which means private security...which means more guns...which means more headaches for somebody. Probably us."

Wanda thought that maybe they were worrying too much. "You guys know I can move things with my mind, right?" Wanda asked.

"Looking over your shoulder needs to become second nature." Natasha said.

Meanwhile, Sam has also positioned himself at the rooftop of another building, overlooking the city as well.

"Anybody ever tell you you're a little paranoid?" Sam asked.

"Not to my face. Why? Did you hear something?" Natasha asked through the comlink.

"Eyes on target, folks. This is the best lead we've had on Rumlow in six months. I don't want to lose him." Cap said.

"If he sees us coming, that won't be a problem. He kind of hates us." Sam said, knowing about Rumlow. After all, he fought him two year ago.

"Don't worry, guys. We'll get him." Sora said. Cap gives out a chuckle.

"This is one reason why you're a keybearer, Sora. You have optimism."

Brock Rumlow was a HYDRA agent within S.H.I.E.L.D., and a former STRIKE Team commander, and he used to work with Cap and Natasha back in the past. He is a world-class hand-to-hand combatant, with extensive experience in various street fighting, martial arts, and military combat techniques. During the HYDRA Uprising back in 2014, Rumlow was ordered to lead the HYDRA team and assassinate Cap and Sora, until he was nearly killed during the Battle of the Triskelion at Washington D.C. when an Project Insight Helicarrier crashed at the side of the Triskelion building, gaining horrific facial scars. Once he recovered, and hearing that HYDRA leader Alexander Pierce had died, Rumlow escaped from the hospital where he was staying and assumed the code name Crossbones, became an independent terrorist, setting out on a path to exact revenge and make anyone involved in his downfall suffer the same pain and loss he endured.

They had been looking for Rumlow for almost 2 years, and they'd finally track him down here in Lagos.

Cap was was looking out the window and noticed a garbage truck on the street, heading towards the direction of the Institute for Infectious Diseases.

"Sam, see that garbage truck? Tag it." Sam then deploys a drone from the back of his jetpack. Sam pilots the drone, known as Redwing, via remote control and flies it towards the garbage truck. The drone flies underneath the truck.

"Give me X-ray." Sam ordered.

The Redwing then use its special camera to scan the truck. It shows the truck's max capacity and the driver carrying a gun as well.

"That truck's loaded for max weight. And the driver's armed." Sam said.

"It's a battering ram." Natasha said.

"Go now." Cap ordered through the comlink.

What?" Wanda asked.

"He's not hitting the police." Cap warned before leaving his hideout.

Sam jumps off the building and deploys his jetpack's wings before flying off to intercept the truck.

At the entrance to the Institute for Infectious Diseases, a group of security guards were on the lookout until they see an incoming garbageg truck. They then see the driver bail out, leaving the truck to head straight for the entrance. The guards were about to take action, but the truck has driven through the entrance. Suddenly, two moving trucks enter the facility before a group of Rumlow's mercenaries appears out of the trucks and open fire on several security guards. Rumlow, in his Crossbones battle suit and wearing a gas mask, exit one of the trucks and starts making his way to the facility. Rumlow's men then starts shooting poisonous gas at the building, causing the people inside to panic and cough as they breathe the gas before passing out.

One mercenary was on alert until he hears a whooshing sound from the sky. The mercenary didn't have time to react as Cap rams into him with his shield, crashing into the window of a nearby car. Cap then use his shield to take cover from machine gun fire before using his superhuman strength to kick a pickup truck to knock down one mercenary. Cap then threw his shield to strike another merc before the shield came back to him. Cap then charged at another mercenary on top of another pickup, making him crashed at the wall of the building, knocking him out.

Wanda uses her powers to create a red force field to repel bullets before using her telekinesis powers to make the gunman stop.

"Sam." Wanda said before using her powers to throw the mercenary towards Sam. Sam then catch the guy and threw him back at the concrete.

"Four." Sam commented.

Wanda then use her powers to create a force field again to give Sam and herself cover from machine gun fire from three mercenaries. Sora and Kairi followed through and got into a battle with a couple of terrorists. Apparently, they were no match for the Keyblade couple. One tried to shoot but Kairi blitzed a couple of mercs while Sora launches a spinning attack knocking a merc down.

"Three." Both Sora and Kairi in unison. While they took of the three mercenaries as Sam uses the Redwing to find and confirm Rumlow's location.

"Rumlow's on the third floor." Sam informed.

"Wanda, just like we practiced." Cap said.

"What about the gas?" Wanda asked.

"Get it out," he said. The move they had practiced involved her using her powers to throw Cap across distances too far for him to jump. It worked to perfection. Red energy reached out to him and catapulted him up and through a third floor window. He landed and knocked the nearest gunman sprawling, then ran farther into the building, looking for Rumlow, punching various gunmen and removing their mask on the way. Meanwhile, Rumlow busted through a glass door and yanked a technician before opening a vault containing some hazardous chemical.

"Pack it up," Rumlow ordered.

Outside, Falcon deflected the incoming fire from Rumlow's men while Wanda used her powers to draw the gas out of the building. She built it into a tornado that spun up into the open air, dissipating where it wouldn't hurt anyone else. Remote controlled mini missiles from shoulder mounts on Falcon's armor took care of the closer gunmen, but there was still a lot of them.

Meanwhile, Rumlow and his remaining men exited out of the facility when Rumlow spotted the gas tornado. "He's here."

Inside the building, Cap reached the vault, only to find that Rumlow has already left.

"Rumlow has a biological weapon." Cap informed.

"I'm on it." Natasha said.

"I'll follow you." Kairi replied "Sora, you go find Cap and go after Rumlow." Sora nodded and rushed to follow Cap as Kairi finds Natasha on a Motorcycle. Kairi jumped and held onto Natasha.

Natasha use her bike to knock down a mercenary before firing her Black Widow Stingers to take out another and use the advantage to knock out a third. Kairi uses her Keyblade to knock off the truck's door. . Natasha then fire her stingers at another before Rumlow grabbed her by her hair and pulled her to the top of the AFV. Natasha struggled to get out of his grip and send several punches before sending a stinger at his neck, but it had no effect since he can no longer feel pain.

Kairi tried to help her but a merc stood in her way. The merc had a sword and twirls his sword trying to intimidate Kairi. She gives him a deadpan look and uses her fire spell making the man drop his sword and running out of the battle trying to get the fire out.

"I don't work like that no more." Rumlow said before throwing her inside the AFV. "Fire in the hole." Rumlow said before throwing a grenade at her and closes the door.

Natasha then combat two mercenaries before using one of them to shield herself from the blast.

Cap and Sora made it to the exit before Rumlow fires a shell at him. Cap use his shield to shield themselves from the blast. Rumlow continued to fire at his enemy until eventually he was able to shoot him out of the building where he fell several floors down to the ground. Sora deflected some of his attacks.

"Sam, Nat, Kairi. He's in an AFV heading north." Sora said as the AFV started ramming into cars.

Inside the truck, Rumlow handed the crucial sample to one of his men. "Take this to the airstrip," he said. "We're not gonna outrun them. Lose the truck."

The truck rammed through cars and an outdoor market before Rumlow and his mercenaries bail out, causing panic among civilians. "Where are you going meet us?" one of the mercenaries asked.

Runlow's answer was grim. "I'm not."

Sam was in the air, soaring over the crowded streets. He used his goggles to spot the hostiles. Sam didn't see Rumlow. "I got four," he said. With the help of Wade, he found them using facial recognition software. "They're splitting up."

"I got the two on the left," Natasha said.

"I'll get the guys on the right." Kairi said.

Meanwhile, Cap and Sora also arrived at the scene, looking for Rumlow and spots that his men dropped their gear while innocent bystanders look on.

"They ditched their gear. It's a shell game now. One of them has the payload." Cap said before a magnetic bomb lands on his shield.

Cap threw the shield way to prevent the blast from killing the bystanders before Rumlow punches and knocks down Cap from behind.

"There you are, you son of a bitch." Rumlow said as he walks towards Cap and preps his gauntlets. "I've been waiting for this." Rumlow said before sending a massive right hook to Cap and t the face, knocking him down.

Meanwhile, Kairi, Natasha and Sam are in pursuit of Rumlow's men. Sam knocks one man down before using his wings to take cover from gun fire. Sam knocks the gunman down before checking for the bio-weapon.

"He doesn't have it. I'm empty!" Sam informed.

Kairi was in pursuit of the two men who trying to escape.

"Who says you can leave?" Kairi quipped, landing on of the men. One merc tried to punch her but He countered with a payback strike, Sora taught her.

"What's wrong?" Kairi taunted. "Can't handle a woman like me?" The two mercs growled and rushed over to him but Kairi uses her ice spell to knock them out cold. Se then goes to check the bio-weapon.

"I'm clean. They don't have it, either.

Natasha was in pursuit of the final two men. One of them has the bioweapon.

"Out of the way!" Natasha said to the bystanders.

Natasha managed to knock one man down before she started to exchanged punches to both men before grabbing a pistol and aiming at one of the mercs, but the man also held a pistol and aim at Natasha.

"Drop it. Or I'll drop this." one mercenary said, threatening to kill everyone in the surrounding area with the bioweapon. "Drop it!"

"He'll do it!" the second mercenary yelled.

Before Natasha can reluctantly comply, the Redwing suddenly appeared and killed the mercenary carrying the bioweapon. Natasha killed the second before managing to secured the bioweapon before it can hit the ground. Natasha then looks at the Redwing.

"Payload secure. Thanks, Sam." Natasha said.

"Don't thank me." Sam grinned.

"I'm not thanking that thing." Natasha said, refusing to thank the drone.

"His name is Redwing." Sam commented.

"I'm still not thanking it." Natasha said through Sam's comlink.

"He's cute. Go ahead, pet him." Sam commented.

"Good job, guys. Now we gotta get Rumlow." Kairi said.

Meanwhile, Rumlow continue to pummel Cap and Sora. Both exchanged punches.

"Come on!" Rumlow shouted.

Rumlow then headbutted Cap before giving a right hook. Rumlow then managed to pinned Cap at a nearby wall.

"This is for dropping a building on my face." Rumlow said before exposing a blade from one of his weaponized gauntlets.

Rumlow attempted to kill Cap however tripped. He looked behind to see the Keybearer glaring at him. Cap took the time to recover and elbow Rumlow. Rumlow exposed another blade from his remaining gauntlet. However, Cap was able to dodge out of the way of Rumlow's deadly attacks. Rumlow continued fighting until Cap delivered several powerful punches followed by Sora slashing him, damaging his mask and, with a final power kick which sent Rumlow flying backwards, overthrew him out of his chance for victory. Cloud looks over at Sora and grinned.

"Good work, Sora." Sora grinned.

"Thanks, Cap." He said. Cap grabbed Rumlow "I think I look pretty good, all things considered." Rumlow said.

"Who's your buyer?" Cap demanded.

"You know, he knew you. Your pal, your buddy, your Bucky." Rumlow said, making Cap look emotional and distracted.

"What did you say?" Cap asked.

"He remembered you. I was there. He got all weepy about it. Till they put his brain back in a blender. He wanted you to know something. He said to me... 'Please tell Rogers. When you gotta go... you gotta go'." Rumlow said before having a serious look on his face. "And you're coming with me."

Rumlow armed the bomb applied in his own suicide vest, intending to take Steve's life along with his own. Just as Rumlow activated the bomb, Wanda used her powers to contain the explosion as Rumlow screamed in horrific anguish as his body was consumed in the fireball. She was able to whisk his exploding body away from Capbut unintentionally placed him next to a building filled with several Wakandan nationals. Wanda couldn't contain the blast and the explosion killed Rumlow and the Wakandan nationals. Wanda looks at the building and covers her mouth in horror just as Kairi arrives at the scene.

"Oh, my..." Cap said in horror.

"My God..." Kairi said with wide eyes.

"Sam... we need Fire and Rescue on the south side of the building. We gotta get up there." Capsaid as Wanda starts to hold back the tears and Sora and Kairi rushes over to comfort her.

Meanwhile not far from here, a man with a Organization XIII coat looks from afar. He was atop of a building studying the two Keybearers comforting the Scarlet witch.

"Sora is stronger than I remember..."

And that's the first chapter. What does this man mean that Sora is stronger then he remembers? Well we won't find for a couple of chapters. I hope you enjoyed this first chapter and please read, review and stay safe. Bye!
