I don't own Kingdom Hearts or Frozen. They belong to Disney and Square Enix. Alright, let's get some things outta of the way, first this story isn't connected to my other Kingdom Hearts and Frozen crossover, Prince of Arrendelle, in anyway minus the first chapter title. This story is going to be a bit more on the serious side so no breaking the forth wall as much. There will be other worlds to go to most will be Disney and some won't be. I plan to more focus on finishing my other KH Frozen crossover before really getting into this one. I thought about it for awhile before deciding to start the first. Enjoy.

Kingdom Hearts: Infinity War

Chapter 1: Prince of Arrendelle

In the Kingdom of Arrendelle, Queen Elsa looked through the her library, before turning to around gasping in shock, "Oh my gosh... I didn't see you there!" She calmed down, "Sorry... I guess I'm still a little new to company." Elsa smiled, "Welcome to Arrendelle, I'm Queen Elsa of Arrendelle."

"Okay... so you all know my story... well technically it's my sisters . I was born with ice powers. I hurt my sister. I started an enteral winter. Love thaws. However, there's a side you may not quite have heard off. In fact, in most versions, you've heard of are just the brief versions. This is actually's Sora's story as well as Anna's." Elsa smiled before turning to the turning to the screen, "Who's Sora?"

She chuckled as she pulled out a book from a self and sat in a chair, "I gotta start you way back. In fact, it's start's when my father was just a prince..." She opened the book as she read, "Many years ago, my father was taking my mother through the garden..."

The young couple walked through the garden, the young prince, picked a rose and handed over to the young princess. She giggled as she took the rose and smelt it. She then leaned in to kiss him as he leaned in as well when the heard something coming. They looked up to see something coming down from the sky a crashed in the ground, they looked away when it crashed, when they looked back, they were shocked to see what they saw, "...a shoot star had crashed into the ground... well that's my parents believed it was until they got a better look..."

They walked up closer to the mysterious object, "It was some kind of sword... in the shape of the giant key." The couple turned to each other what it was, the prince told her, "Wait here..."

She nodded as went to take a better look. He examined the key like sword. After a minute, he held the handle and tried to pull it from the ground, "My father tried to remove the weapon from the ground... but it refused to budge. No matter how hard he tried." He struggled to the weapon from the ground but it refused to budge. He eventually gave up as the princess walked to her boyfriend's side, "What is it?"

"I'm... I'm not sure." He admitted as he couldn't look away from the blade. "He reported at what happened to my grandfather... he's never seen anything like it. No one on our world has... It was insane! Fortunately... my grandfather new just who to call..."

Later, that day, the King, Prince, Princess, and the troll walked up to the key shaped sword, "His name is Grand Pabbie. That's right... the same troll who save Anna the first time, the same troll who helped raised Kristoff and Sven, and warned me fear would be my enemy. He's been around a long time. I gotta remember to ask Kristoff how old he is." Grand Pabbie placed a hand on the blade, the King asked, "Well... what is it?"

"A Keyblade..." Grand Pabbie answered in awe. The Prince asked, "A what?"

"Listen to me... this brings much news... bad and good. A great evil is coming... and it will reek chaos on all life as we know it. Not on this world... but all worlds." The royals gasped, as the Princess asked, "How much time do we have?"

"I could not say... days, years, it could be even eons from now." Grand Pabbie admitted. The King asked, "You said there was also good news."

"Yes... hope. This Keyblade... it has the power to repel the coming darkness. It coming here means... someone can take the blade and maybe the only human alive that can stop this evil." They all smiled at that, they were given the weapon by God to try to stop the evil, Grand Pabbie added, "However... only one pure of heart... a heart of a hero... can take the blade. No one else can."

Grand Pabbie turned to them and rolled up to the king, "Your Majesty... if we are to stop the coming darkness we must find this hero."

"My family took his words to heart. He's never been wrong before. My Grandfather call out wide, from Weaslton to the Southern Isles... for someone... anyone to wield the blade..." Weekspast and men and women a like came along to try to pull the Keyblade from the ground, "But none could lift it. I swear... it was like the story of King Arthur."

The King and Prince watched at the failed attempts, "Eventually, my grandfather past and my father married my mother and took the responsibility of trying to find the heroes. Years past, and well, I was born... Anna came along a few years after."

The two young Princesses giggle as the played in the garden when they spotted the Keyblade, "Of coarse out parents told us of the story... Anna really wanted to be the hero..." The little red headed girl tried to pull the blade but failed and fell on her butt. Elsa giggled at Anna's attempted as she joined in the giggling, "I, of coarse, had no interest of being the hero..." Elsa and Anna walked off to play some where else...

... when Elsa returned to try to pull the Keyblade from the ground. "Okay... I lied... I attempted to pull the Keyblade as well when Anna wasn't looking..." Elsa stuggled when she turned to see a giggling Anna. "And I couldn't even do that right."

The older sister smirked as she used her magic to throw a snow ball at her little sister. Anna shook off the attempt as she ran after Elsa, who both laughed, "Of coarse as you know... our fun didn't last."

Elsa had accidentally struck Anna with her powers trying to catch her, "ANNA!"

"Yeah... the tragic day... this is the part where Grand Pabbie had to save her... and my father had to lock the gates, reduce the staff, limit her contact with people and keep my powers hidden from everyone... including Anna."

Anna, with a new white streak in her hair, rushes to the hall to see Elsa shut the door to her new room. Anna watches, confused and sad.

"That didn't mean she didn't give up on me..."

Little Anna skips up to the window. She lights up at the sight of the snow and rushes down the hall and knocked on the door, "Elsa?" She sang, Do you want to build a snowman? Come on, let's go and play!" Anna peeked under the door, "I never see you anymore... Come out the door... It's like you've gone away..."

"We used to be best buddies... And now we're not... I wish you would tell me why!" Anna played with two dolls, but gave up. Anna peeks through the key hole, "Do you want to build a snowman?" Anna calls through the keyhole, "It doesn't have to be a snowman..."

"Go away, Anna." Elsa told her. Anna turned away sad, "Okay, bye..."

Years later, an older Anna ran up to the door singing, "Do you want to build a snowman? Or ride our bike around the halls?" Anna rides a bicycle built for two in the hall by standing on the back seat until she crashed into a suite of armor. She then ran into a room full of paintings, "I think some company is overdue... I've started talking to the pictures on the walls!"

"Hang in there, Joan." She told the painting of of the courageous Joan of Arc. Anna then laid at the base of the grandfather clock, playing with her braids, bored out of her mind, "It gets a little lonely... All these empty rooms... Just watching the hours tick by..." Anna's eyes follow the grandfather clock's pendulum as she clicked her tongue, "Tick-tock! Tick-tock! Tick-tock! Tick-tock!"

"I wanted to say yes... Every time she sung that song I wish I could say yes! But... I couldn't I feared my powers would hurt her and countless others. And my powers were only getting stronger. On my eighteenth birthday with no luck with finding the hero or having any luck controlling my powers, our parents left to search for the answers for both... and... they were both lost at sea. It was a sad day for the whole kingdom... even more so for myself and Anna..."

After the funeral, Anna walked up to the door and knocked, "Elsa, please, I know your in there. People been asking where you've been... They say have courage and I'm trying to... I'm right out here you... Just let us in. We only have each other... it's just me and you... What are we going to do?" Anna slide down the back of the door and asked once more, "Do want to build a snowman?"

"You know, why I didn't opening dispute the fact, I wished to morn with my sister... anyways, you know what this means... just three years and they'll make me Queen... So, with nothing left to do, I began to prepare for the day..." Elsa sat alone in her frozen room. Weeks past as she prepared for the Coronation Day, just then a knock on the door, she opened the door to see the mailman hand over serval packages, as the future queen signed for them, he left them in her room. She closed the door, "Then weeks after, my packages came in for my dresses for the big day... however... this was the day when my life changed forever..."

Elsa walked to her bed and sat on it as she began to cry to herself. Suddenly, one of the packages made a light tap startling Elsa. She waited until she heard the tap again walked up to her new packages. she lifted up one of them and seperated from the other packages. She slowly and carefully opened the package. "Now, I remembered everything I ordered had came... the new crown, hair brushes, my new dress... except there was wasn't just the dress in the package..."

Elsa gasped at what she saw, and took a few steps back. "There was also a tiny cubby baby boy as well." The baby yawned as he just woke up and smiled at Elsa's presence, "Ga..." Elsa was speechless, "What... what the..."

She the catiously looked around... "There was no note, no letter... nothing... of where the boy came from..." She reopened the door and the delivery man was long gone, "I... Waited for someone to come... Looking for him. But no one did."

Elsa paced around waiting for someone to come a long, staring at the door as they baby sucked his thumb. She sighed as she went to pick up her others packages, as she turned to away, the baby started crying. Elsa paused as she turned to the baby as he reached out to her. She quickly put here things down and quickly returned to the baby. She almost picked him up but remembered that was bad idea so she picked up the package he was in and began shaking it. The baby stopped crying before looking at Elsa in confusion. She simply stated, "Trust me. This is the best for both of us."

She then placed the package on the bed, she sighed, "Okay... clearly... no one's coming for you..." Elsa paused as she thought what to do next, "I guess I have someone from the castle drop you off at the orphanage and they'll find you a new home." She then reached for here desk to grab some paper and a pen but when she touch the objects they froze instantly. Elsa gasped, "No... no... no..." Elsa closed her eyes, "Conceal it... don't feel it... don't let it show..."

She then heard a tiny sneeze and snow appeared over her head, she didn't do that. She then turned to the baby who was trying to climb out of the box, the box tipped over and the baby landed on the bed with a thud and snow appeared around him. The baby looked around and giggled at that. Elsa stared in amazement. She for the first time slowly removed her gloves and picked up the baby boy. They baby didn't even flinch at her cold hands. Elsa stared at him as the baby reached out for her as tiny snowflakes came out of his palms. Elsa slowly began to smile, "You're... you're like me..."

Slowly as she brought the baby closer in her arms the baby touched her free hand with his own. The baby cooed as she smiled. "It was amazing... the cold didn't bother him... for the first time in forever... I wasn't alone."

The baby giggled as she gave a soft chuckle before she frowned and sat on the bed, "I can't hand you over to the orphanage... they'd... they'd never understand..." She then looked back at the baby as he turned his head and giggled. Elsa smiled as she stood up.

"I brought him inside." Elsa carried him to her bath room.

"Gave him a bath." Elsa filled the sink with soap and water and began wash the baby. As she washed his brown spiky hair, he managed to grab the soap and was about to suck on it as she quickly pulled it away accidentally freezing it making the baby laugh.

"Feed him." She managed to warm up some milk for the baby and used an old baby bottle to make him drink it.

"Changed his dipper. Which was not easy for someone who never learned to do it." Elsa threw away the old dipper and tried to get his new cloth dipper on him. As she read a book how to do it. Took a few times before she got it to stay on. She then wrapped in in some of her blankets in her room. The baby smiled and giggled, as Elsa gave a smile back. "And then I made the decision, that would change my life forever... to raise him as my own son."

The baby gave a small burp. Elsa giggled, "Excuses you." She then realized, "I suppose you need a name."

She gave it a thought, "How about... Peter? No... that name's a bit overused... Mosses? No, that doesn't really work..."

She gave it a deeper thought, she noticed his eyes were blue like the sky. She then remembered a Japanese translation for it. She smiled, "I know... I'll call you... Sora... my little Prince."

Sora beamed, "Ga... ga...!" Elsa smiled as she failed to notice her own room was thawing out. "And from that moment on, my life had been that much better. And that's just the beginning of the story."

"With every ending comes a new beginning... Two worlds, one family... Trust your heart... Let fate decide... To guide these lives we see!"

Put your faith in what you most believe in... Two worlds, one family... Trust your heart... Let fate decide... To guide these lives... To guide these lives we see! Put your faith in what you most believe in... Two worlds, one family!"

And that ends the first chapter of the story. To answer a few Questions, from time to time, Elsa does narrate part of the story... but not always. I thought I'd give it a try. Yes, in this story, Elsa rasies Sora as her own son. Oh, and I'm not planning to make an over complicated Avengers/ Heroes Of Light team in this. It'll just be Anna, Kristoff, Sven, Olaf, Sora, Riku, and Kairi... Maybe Donald and Goofy as well. Only parings so far are Sokai and Anna/Kristoff with a little Hans/Anna because you know the story. However, things do go a little differently from here. And yes Thanos is a major villain in this story. Next chapter, we'll see how day two is going for Elsa raising baby Sora. What do you think? You like it so far. Be sure to leave a review and please be nice. Oh and don't forget to follow and fav. as well! See you next time!
