I have always wanted to do this but I never can think how I can write it until now... This is a crossover between Kingdom Hearts and the Batman Arkham games. Since the title is called Arkham Asylum, it will take place in KH1 and Arkham Asylum. This story is about Batman and Sora finding the Joker but it's also gonna be also about Sora and Batman's relationship.


Prison... an unusual landing spot for Sora, Donald and Goofy. They all walk through an island. Sora crossed his arms there's something... different about this place. This place felt dark while the other worlds felt light like Wonderland.

"Donald, do you know what world this is?" He asked his feathered friend.

"According to the world map on the gummi ship. We are a place called Gotham City." He answered his friend.

"Gotham City, huh?" Sora looked up at the prison that had a sign on top of it called Arkham Asylum. "Well it sure looks gothic." He chuckled before noticing a door. Sora went to open the door but it opened automatically. Before they reached inside they see Heartless attacking... a man dressed as bat whom got off the vehicle. He attempts to punch one but it has no effect. Suddely a Soldier Heartless hit his face, knocking him on the ground. Sora growled. He has to help this guy. No matter how strange is dressed up as. He jumped of him, surprising the Dressed bat.

"What are you doing?" He demanded.

"Saving your butt." Sora grunted as he raised his hand and magically summoned his Keyblade. The man's eyes widen in shock.

"Can it be? Is that the Keyblade's chosen one?" But before the Heartless knew it they were all vaporized by Sora's Lightening. Seeing that there were no more Heartless. He helped the man up.

"Are you okay?" He asked. The Man nodded.

"I'm grateful that you saved me." The Man said but didn't smile. Sora noticed something... familiar about him. It was like he met him before.

"No problem. I'm always glad to help people when Heartless are involved." The man's turned away from him then looked up at the sky.

"So those things that attacked me are the Heartless. And you must be the Keybearer." Sora gasped. Except for Traverse town, he's never met people who heard of the Keyblade mythos.

"How did you know?"

"I read about it a long time ago when I first started fighting crime." He said then turning back to him. "But let's cut to the chase here. You are here from other worlds to stop these creatures and only you can stop them. Once I get done here, you can help me discover more Heartless at my hideout." Sora was still surprised but nodded his head.

"Sure I can help you. What is your name?" He asked. The man stopped then gave Sora glare. "Can you tell me who are?"

"My real name shall not be named under any circumstances." He said silently. "But everyone calls me... Batman."

"Batman, huh? I'm Sora. This is my friends. Donald and Goofy. You won't tell anyone we are from other worlds, right?" Batman nodded.

"My lips are sealed." He then looks at Donald and Goofy. He narrowed his for a minute because he heard the name Donald and Goofy before. He then looks at the two creatures. One of them appears to be a duck in a mage outfit while the other is wearing a long green jacket with golden pants. He then snapped his fingers.

"Of course. I've heard of you two before. Your king came here." Both Donald and Goofy happily gasped.

"He did?" Asked the duck.

"Where is he?" Goofy asked. Batman lowered his head down.

"I have no idea. But I need to two to do something for me. I am sending the batplane to pick you up to my hideout called 'The batcave.' Your king gave me something and told me that only you two should see and wait to give it to Sora when the time is right."

"Well why can't they give it to me now?" Asked Sora.

"Because he told me that you are not experienced much yet. And he plans to give it to you when the time is right." Batman told him. Sora pouted but nodded. In just a few seconds the Vehicle called the batwing came by and picked up Donald and Goofy. Sora looked up and waved goodbye to his friends. He then turned up to Batman.

"So now what?" Batman didn't answer him. Instead He opened his Batmobile door and grabbed a man with... white skin, green hair red lips and purple clothing. He was laughing crazily while hancuffed. Sora gave a disgusted look. There was something... awful abou the clown. He just keeps on laughing.

"I gotta take this clown back to Arkham. C'mon." Sora didn't say anything but followed Batman to the Asylum. The doors opened as Batman pushed the clown down to his knees. Sora stood next to Batman as the doors slide open. Batman yanked the clown and pushed him forwards.

"Get in there, Joker." Batman grunted. Sora followed him still amazed by the prision's imagery.

"Hey Sharpie! Love what you've done with the place." The Joker commented at the old balding man wearing a suit and holding a cane.

"That's warden Sharp to you." The man glared. Not noticing Sora beside Batman. "Boles." He turned to the buzz cut tough looking cop stomped over to the Joker."Yo Frankie! How's the wife and kids? You miss me?" Joker exclaimed as if he was seeing an old friend.

"Shut it clown! A lot of people really want to talk to you!" He growled before pushing the tying up the Joker in the trolley then tightened the straps.

"Get that filthy degenerate out of here" Warden Sharp snarled as the madman's giggles bounced eerily over the walls. Batman stood there. He had a bad feeling about the Joker.

"Warden, something's not right. I'm going in with him. C'mon Sora." He said. Sora nodded and followed, Batman the doctors taking the Joker. He turned to one cop.

"Is Commissioner Gordon here yet?" He asked him.

"Yes sir, he's, err, waiting for you down at Patient Handover. He got here just before you did," the guard replied. He then noticed Sora with him.

"Who's the kid?" He asked Batman. Batman looked back at Sora then answered his question.

"Let's just say that he and I need to talk about something. Important." The Guard raised his eyebrow but shrugged it off. After all he's safe with Batman. While Batman walks with Sora, He lowered his head and whispered to his ear.

"Listen Carefully Sora. The Joker may not look threatening but believe me, that's a part of his act." Sora nodded in agreement.

"I bet. There's something about him that's extremely... insane about him."

"Well I hope this is only time you see him." He said while they enter a small room.

"New patient in the Intensive Treatment lobby. All non-essential staff are to vacate the area." a female voice sounded out.

"It's always nice to return to my sweet little haha-hacienda!" the Joker said as he was continually dragged by his stretcher. Sora tried to shake the feeling of dread from his mind as they entered into a smaller room.

"Tunnel's full. Start the scan!" they heard another voice say.

"Scan initializing," another voice said, several machines began scanning the room with cobalt light.

"Y'know what? I prefer the good ol' cavity search. Much more personal. I bet you had one kid. C'mon tell me her name. Karen? Sharen?" Sora blushed while giving the clown a glare.

"Don't let him get to you." Batman whispered.

The scan began flashing red, letting out a loud beeping sound.

"Multiple prohibited items," the voice said.

"I want Joker searched again!" another voice responded, obviously irritated.

"Err, it's not the patient. It's, err..."

"Ooh! Whatcha sneak in with you, Bats? C'mon, tell me! Batarangs? Batclaws? Bat-snacks... Bat Credit Card."

"A Bat Credit card?" Sora asked. "For some reason... that sounds really stupid."

"Scan is green on Joker." The voice said.

"Open the gate! Get him out of there!" the last voice shouted.

"I want weapons on him at all times. Do not let him out of your sight," the door opened to reveal a man with darker skin pointing his own gun at the Joker. Sora noticed that this man had a hook where his left hand should be, he guessed that it was most likely lost in an accident.

"There'll be enough time for you later, Cash. Speaking of time, tick, tock, tick, tock. Is that a crocodile I hear?" He asked while laughing insanely. They walked through a prison came to another huge, steel door where a doctor and a couple more guards were waiting.

"Just got to check your prisoner, Officer Boles," the doctor said. He was dressed in a plain, beige scrub top and matching colored pants and holding a clipboard.

"Whatever, just be quick!" Officer Boles replied.

"Just following procedure! Patient seems to be in satisfactory condition. Looks like he suffered minor lacerations, probably in the last 2 hours. There seems to be…"

"BOO!" the Joker screamed, then started laughing. "Need to take my temperature? I'd be happy to drop my pants."

"He's all yours. Get him out of here," the doctor said.

"He's good. Get the door open," one of the many guards surrounding the Joker ordered.

Then the giant door slid open and the guards, once again, pulled the Joker through.

"Alert in Intensive Treatment. Category 9 patient in transit. Pacification system active. Shoot to kill permissions granted," A female voice echoed through the room.

"You heard the lady. We got another psycho on the way!" another guard shouted, the creaky sounds of an old elevator ascending.

"Can you smell the excitement in the air? No? Must've been one of the guards..."

Sora widen his eyes as something big, really big, emerged from the old elevator, having to crouch to even fit inside the old machine.

This beast was dressed only in orange pants, it's body was covered in green and grey scaly skin.

"Croc, old boy! Is that you!?" the Joker turned to see the beast that was being carried by the old, creaking elevator.

Then it did something strange. This crocodile's head shot up and began sniffing the air before turning to face Batman and Sora.

"I've got your scent, Batman. I will hunt you down," he spoke in a dark and scratchy voice before the collar around his neck lit up, causing him to growl in pain as electricity coursed through his neck.

"A toy collar won't keep me from killing you, Batman. I will rip you apart, eat your bones." Croc threatened as he was lead away from the guards before stopping. Sora looked at him and gulped.

"Don't worry. He's being put in his prison. He's all locked up there." Batman reassured. Sora nodded as they walked towards the elevator.

"Wee! Great night for a party!" the clown squealed in sick delight as they descended inside the elevator.

"Not where you're going." Batman sneered.

"Oh... The night is young, Bats. I still have a trick or two up my sleeve. I mean, don't you think it's a little funny how a fire at Blackgate caused hundreds of my men to be moved here?" he asked before chuckling quietly.

"I thought I told you to stay quiet!" Boles yelled, shaking the gun in his arms threateningly.

"Oh Frankie..." Joker replied. "You really should learn to keep that fat mouth or yours shut. It'll get you into trouble."

"Tell me something. You've never let me catch you this easily. What are you really after?" Batman demanded.

Oh nothing much, Hundreds dying in pain and fear. All their meaningless lives brought to a horrifying conclusion. All thanks to you and a book of matches. Was that the answer you wanted?"

Sora rolled his eyes then heard the warden continue to speak. But he tuned out his voice as he tried to understand what this guy was talking about. It was almost as though he wanted to be he...

"Ha ha ha." Joker suddenly burst out laughing as the lights suddenly went out, watching as the two guards nearly panicked as they tried to see in the dark.

"What's he doing!?"

"Stay where you are!"

"Get a flashlight! Get a light on him!"

His deranged laugh was cut off by a choking threw his head at the back of the cart.

The elevator stopped.

"Our guest has arrived," a guard announced and the doors opened.

"So, you're back. You killed 3 of my crew when you busted outta here," an angry male voice growled at the Joker.

"Only 3? Hahaha! I'll be sure to try harder next time! What say we aim for a hundred?" the Joker laughed.


This is chapter one of what I think the crossover. I know some people don't like this crossover but I think it can work. I can't wait to write Sora and Batman's relationship. It will be developed in the next few chapters. Until then see ya.
