A/N I don't own Kingdom Hearts nor Captain America. They belong to Disney, Square Enix and Marvel. Okay guys... this is the first chapter. Yeah I know I said I would do MCU-KH Oneshots but I wanted to get this out of the way first. The first half of this chapter will have Cap racing Sam. Then after is the wedding. Chapter 2 will have Cap's mission and SoKai's Honeymoon but with a twist. I can't wait for you guys to read that part.

It was a beautiful day in Washington DC as Steve Rogers who is also known as Captain America is jogging. He was running around a circuit until he finds another man jogging. He has dark skin and a beard. Steve runs past him shouting...

"On your left." The man said nothing in return and Steve kept running.

"Oh, it's on," he murmured under his breath, pushing himself to go faster, a grin on his face.

He hadn't managed to catch up to her though, despite looping back around the path he'd been taking. He spotted the man from before and called out another, "On your left," as he passed.

"Uh-huh," The man muttered, "On my left. Got it." Within maybe ten minutes, he was upon the man again. He must have heard Steve coming because he turned his head slightly.

"Are you serious?" Don't say..."

"On your left."

"Oh, Come on!" The man cried out. Steve gives him a laugh. After that, he had enough jogging. He sit under a tree to catch his breath as he took a stop at a park.

"Need a medic?" Steve asks.

The guy laughs. "I need a new set of lungs." He pants, "Dude, you just ran, like, 13 miles in 30 minutes."

"I guess I got a late start."

He chuckles, "Really? You should be ashamed of yourself. You should take another lap." He looks away for a second. "Did you just take it? I assume you just took it."

"What unit you with?" Steve wonders.

"58th Pararescue. But now I'm working down at the VA." He holds up a hand "Sam Wilson."

Steve helps Sam up, "Steve Rogers."

"I kind of put that together." Sam pants, "Must have freaked you out, coming home after the whole defrosting thing."

Steve sighs. "It takes some getting used to. It's good to meet you, Sam."

Steve was about to leave when Sam calls out.

"It's your bed, right?"

"What's that?"

"Your bed, it's too soft. When I was over there, I'd sleep on the ground, use rock for pillows, like a caveman. Now I'm home, lying in my bed, and it's like…"

"Lying on a marshmallow. Feel like I'm gonna sink right to the floor." That's not the only reason why I'm down. I wonder how Jackie and Arthur are doing. "How long?"

"Two tours." Steve nods in appreciation. "You must miss the good old days, huh?"

"Well, things aren't so bad. Food's a lot better. We used to boil everything. No polio is good. Internet, so helpful. I've been reading that a lot, trying to catch up." Thanks to Jack, I'm almost current on what's happened these past few decades.

"Marvin Gaye, 1972, Trouble Man soundtrack. Everything you missed jammed into one album."

Steve nods. He pulls out a little notebook. "I'll put it on the list."

On his list was...

I Love Lucy (television), the moon landing, Berlin Wall (Up & Down), Steve Jobs (Apple), Pisco, Thai Food, Star Wars/Trek, Nirvana (Band), Rocky (Rocky II?) and now Trouble Man (soundtrack). Star Wars has been crossed out already. He had a Star Wars marathon of the original trilogy at the apartment with his friend Sora (They haven't seen the prequels yet, because Tony didn't mention them. When Sora found about them he asks Tony why he didn't mention the prequels, Tony said "Three words... Jar Jar Binks so they dropped the subject) Speaking of Sora, Steve's phone begins to ring. He flips it open to see the text was from Sora.

"Hey Cap, where are you? The wedding starts in 6 hours. Do you have the ring?" Steve went to check his pocket and inside was a black box. He looks over to his new friend.

"Sorry, Sam. I gotta wedding to go to." He shakes his hand.

"You take care, my man. Any time you wanna stop by the VA, make me look awesome in front of the girl at the front desk, just let me know."

Steve smiled at the young man. "I'll keep it in mind."

"Okay." Sam replied.

St. Patrick's Cathedral, New York City.

In a well designed room, Sora is preparing for his upcoming marriage with the love of his life, Kairi. Things like Heartless, Nobodies or Evil villains don't make him nervous but today to say he's nervous is an understatement. He is so nervous that he is pacing all over the room, irritating all of the groomsman Tony sighed, he and the other groomsman are waiting for the Best Man Steve Rogers whom hasn't come back from Washington.

"Sora would you calm down? You're making me nervous." Tony said. Sora looked at the man who is gonna give Kairi away.

"Calm? I am calm I mean how could I not be calm, I've been dreaming of this day since Kairi came to the Islands. Why would I be nervous?"

"Because your wedding is being televised because you helped saved the world and everyone is treating it like the Royal wedding?" Asked Bruce. Sora's face started to turn green. Tony gives Bruce a glare.

"Thanks a lot dipshit."

"Language. After all we're in a Church." A Familiar voice called them. Sora turned around and relieved to see Steve finally made it. He is dressed in a black tuxedo with a white shirt, blue tie and a rose attached to it.

"Finally Cap. Did you bring the rings?" Steve Smiled as he gives the ringbox to the groom.

"Thanks, Cap. And thanks again for being my best man." Steve puts his hand on Sora's shoulder.

"No problem, Sora. You've been through a lot of crap, you deserve happiness. Kairi is a special woman. Enjoy the moments with her... like I wish I had with Peggy." Sora felt bad for Steve that he didn't have a chance to be with the woman he loves. He gives Steve a pat on the back.

"Don't worry, Cap. I will savor every moment with her." Steve smiled.

Sora jumps and gives Steve a hug. Steve felt awkward at first but he hugged his friend back. After they heard a knock on the door.

"Come in." Sora said. The door was opened by the wedding planner with a clipboard.

"Sora, it's almost time. Are you ready?"

"One moment." He said. He walks over to a table and picks up Kairi's lucky charm. She gave him Last night before they could see each other. He pins it onto his tuxedo. He takes one more look at the mirror and admires his handiwork. He turns to the Wedding planner.

"Okay, now I'm ready."

"Well then... better go get the bride. She's waiting for you." Tony said as he walked out of the dressing room first. Sora stayed for a moment with Steve, Bruce and Clint.

"You know it's too bad Thor couldn't come." Sora commented.

"Yeah, well he's probably busy up in Asgard." Bruce said

"I talked to Thor a little while ago. He said 'while I couldn't come, give Sora my regards.'" Sora smiled.

"Yeah, well next time you tell Thor, I said thanks. I understand why he couldn't come. He has to keep an eye on Loki. But for now let's not worry about that." He exclaimed as he jumped off out.

"Time to get married."

This was it. After years of waiting. After years of playing with one another. After fighting together, stopping evil like Xehanort, Maleficent and Loki. Now he is having the biggest day of his life. Today is the day he and Kairi become husband and wife. He stands there patiently for the bride. He looks at the church which is filled with New Yorkers, Politicians and fans. Ever since their encounter with Loki, Sora and Kairi grew quite a popularity. They got on Talk shows, threw out the pitch and sometimes spends days at the hospital telling sick children about their adventures. He looks and sees up front is Nick Fury dressed in a black suit coat and pants. Clint Barton wearing a white shirt and black tie. He smiles and mouthed "Thank you for coming." He felt a hand on his shoulder. He looks behind and sees his best man Steve Rogers giving him a vote of confidence.

After a moment the door open as the bridesmaids walked in. First came in was Natasha Romanoff. Ever since Kairi came to Earth, both women became good friends. You could almost say they're like sisters. She was holding a white bouquet of flowers. The next Bridesmaid came was Pepper Potts, Tony's girlfriend. Like Tony becoming a father figure, she became a mother figure to Kairi. The Final Bridesmaid was Maria Hill, One of S.H.E.I.L.D's best agents. Even though they didn't talk to each other a lot, Kairi still considered her a friend and asked her to be her bridesmaid a week ago. She accepted. Once the bridesmaids finally reached the aisle. The Orchestra started playing "Here comes the bride" As the door opened revealing Kairi in a gorgeous sleeveless floor length wedding gown. Her face was covered with a veil. Sora gasped at the woman who was being walked with Iron Man himsef: Tony Stark. Even Steve was in awe so he whispered to Sora.

"She looks so beautiful. You are so lucky."

Kairi was indeed beautiful in her dress and Kairi blushed as she thinks Sora looked so handsome in his white tuxedo with her lucky charm pinned to it. Once Kairi reached the aisle. She lets go of Tony's arm then she kissed his cheek.

"Thanks, Tony." She whispered. Tony patted her on the back then he turns to her soon to be husband. Sora took a look at Tony and he swears he looks teary eyed.

"Take care of her." He murmured. Sora smiled then he takes Kairi's hands and looks up at the priest.

"Dearly beloved, we are gathered here to present this man and this woman in holy matrimony. Who gives this woman away to be married?" He asked.

"Well... due to her actual father not being here, I took the role as father so... I do." Tony said. The priest nodded. Tony let Kairi go then stands beside Bruce with the other groomsman.

"Now before we go ahead with the 'I dos' Sora may read the vows he wrote to his bride. Sora grabs his vows from his pocket. Unfolded it then clears his voice as he reads it.

"Kairi, ever since we were little I've had this crush on you. I knew it was something bigger once I drew us sharing a paopu fruit at Secret place. But I didn't know how much I loved you until you saved me at the final world. When Xehanort struck you down at Kingdom Hearts, I never felt so scared in my life that after his defeat I had to use the power of waking even though there was a high chance that I will never see you again. Once you saved me at the power of waking with the power of true love... I vow that I will never be apart from you again and that's my promise of a lifetime. Whether it's here on Earth or back at Destiny Islands I hope someday we see our kids playing together in the backyard." Sora finished then he puts his vows back in his pocket. Kairi's eyes began to tear up. She wiped it then she releases her vows from her pocket and reads it to him.

"Sora, I love you. I loved you ever since I first met you. I didn't know about it until you used Riku's dark Keyblade to save me that I truly loved you and I knew you loved me when I saw your drawing of you giving the paopu fruit to me. I teared up and drew one giving it to you. Later when you saved me at the power of waking, I could no longer stand being away from you so I was determined to save you and I'm glad I did. Even if we never go back home, I will always stand by you and we will fight together. I love you more than anything in the world and I will continue to love you and our children when we have them."

Sora's eyes started to cry as she puts her vows back in her dress pocket. The priest smiled then turned to Kairi.

"All right, now that you're finished with your vows. Do you Kairi, take Sora to be your lawfully wedded husband for as long as you shall live and in sickness and in health until death do you part?" Kairi grinned then looked at her soon to be husband and said...

"I do." The priest smiled then he turned to the groom.

"Sora, do you take Kairi to be your lawfully wedded wife for as long as you shall live and in sickness and in health until death do you part?" Sora smiled then turned to look at his beloved Kairi and said...

"I do." The priest grinned as he began the words they were looking forward to for a long time.

"Then by the power vested in me in State of New York, I now pronounce you husband and wife. Sora, you may kiss the bride." Sora felt butterflies after hearing that. He sighs then he lifted Kairi's veil off her face. Kairi feels chills over her spine as She feels Sora's lips touching her lips as the crowd cheered at the couple kissing. The couple then released from each other then bowed to the crowd then left from the alter to leave the reception. This is the beginning of the rest of their lives. And they would not trade it for anything.

A/N Yep it's official. Sora and Kairi are married. Like I said, Next chapter is Cap's first mission in the movie. Hope you enjoy Iron Man, Clint and Bruce's cameo. We won't see them again till Age of Ultron. I'm gonna write a reception one shot. I hope you liked this chapter. Can't wait to write the rest. To quote Tony Stark. I love you 3000.
