The Clash of the Stone and Door

(A/N: Things to know, on the Kingdom Hearts side this is post Kingdom Hearts II. Ignore that DDD ever happened. On the Fullmetal Alchemist side please note that this is the 2003 version. This is sometime after they discover the ingredients to the Philosopher's stone, but they know about Dante! :) Treat this whole crossover as an AU!)

Chapter One - Return of a Dark Presence

"A little cold won't stop me from getting the heck off this train!"

Edward Elric stood from his seat and stared down his younger brother. "But it's not Al! If this cold has the power to make you pass out during a fight with another alchemist then it could be life threatening!"

His younger brother, Alphonse Elric, also decided to stand up and face his brother. He may have been younger but he was bigger and physically stronger than him. They both stared at each other trying to frighten one another into retreating. But it seemed that it wasn't working.

The two were now on a train that happened to be passing a very lush field full of beautiful flowers. There was a blue sky with not a cloud in sight and a large mountain in the background added to the scene. One would think that it would ease the fighting on the train. It would…except for the Elric brothers.

Edward gave up and slammed into the hard seat beneath him and crossed his arms.

"I win again…" Alphonse thought to himself. He then stood up and left toward the front of the train leaving Ed to wonder where he was going. After he was certain that his brother couldn't hear him he began ranting to himself.

"I'm not even sick! What a stupid order! I could've just stayed in Central. We didn't have to come all the way to Resembool!"

He paused with a small sigh and then looked back checking to see if he was nearby.

"So he must've gone to the train doctor to get some medicine…great." Edward waited silently until he heard his brother's clunky footsteps coming at him again. He looked up and saw him holding a small pill in one hand and a glass of cold water in the other.

Edward turned away as he tried to hand him the glass of water, making Alphonse sigh with frustration in his voice, "Come on brother. You can't stay mad at me forever!"

Ed pouted. "Just leave me alone..." a harsh tone in his voice formed.

Alphonse sat down beside his brother and sat the pill and water on a small tray. "Please don't be mad at me you're sick. You can't fight when you're sick like this." He put his hand on his brother's shoulder just as he started having a coughing fit. Edward slightly turned toward his brother and grinned.

"Fine…you win…I shouldn't be so angry at you. Sorry. Really, I am." Edward slightly turned his head and smiled at him.

The train whistle filled their ears as the train began passing over a large bridge. "Brother," Alphonse sighed with a hint of relief in his voice. "You know you should at least have a doctor look at you while we're at Winry's house." Alphonse suggested.

"I guess. I'm only taking medicine because I feel sorry for you!" Edward glared at him while he yelled.

Alphonse turned his head and muttered, "Stubborn as always and just when I thought that you had accepted being sick." Edward clinched up his face at his brother trying to ignore his comment. He really didn't have the energy to argue. He hated showing his weak side. It made him feel….small…and dumb.

He turned and looked out the window at the scenery. His mind began to rush with the memories of the two getting to Central and leaving home to go with teacher, then the time they performed it. Edward sighed and closed his eyes. But suddenly felt the urge to cough again.

He quickly coughed into his hand and leaned back into his seat and looked over at his brother. "Hey Al," Edward said his voice was now gentle and innocent. Alphonse turned towards him. "I promise that I'll make things right again. I will get your body back." His head turned to the window once more. Alphonse knew that his brother was determined to help him. He also knew the reason why Edward didn't want to leave Central was because it would put them behind in their research for the Philosopher's Stone.

"Now, come on let's not worry about that right now. Why don't we focus on getting you better? Here, take your medicine." Alphonse said, picking up the cup and pill. Edward nodded and reached for it but…

The train came to a quick halt. Edward fell forward and smacked right into the window. Alphonse lost his grip on the cup of water and pill. The water splashed on the floor and the pill rolled under a nearby seat. Passengers on the train began screaming and panicking. Alphonse lifted himself up to find that Edward was holding his head. "B-brother?! Are you alright?!"

Edward groaned and nodded, "What the hell was that?" His head was pounding, and he couldn't help but rub it from the pain.

Alphonse stood up and looked around. Suddenly, the door slammed open and black smoke began to fill that cart. Edward began coughing trying not to inhale the smoke, and other passengers began screaming from the other cabins.

"Well, what a surprise! Hello pipsqueak!"

Edward felt his heart stop. That voice! He knew that voice! Why was he here? Did he know that Edward wasn't feeling himself? "Envy?! Why are you here?!" Alphonse yelled.

Edward looked up to see Envy staring him right in the eyes. "Stop calling me small!" Edward clapped his hands and charged at him full force. Right before he reached Envy, he transmuted his Auto-mail arm into a blade. He jumped and sliced Envy right in half...or so he thought he did.

Envy had managed to flip backwards and dodge Edward's attack. Edward fell down to one knee. He had his blade to his side and was holding his stomach. His breathing began to increase and sweat was running down his face. Edward felt so drained. He already knew that Alphonse would have to do most of the fighting. "Fullmetal pipsqueak it's a shame really. You know, that you won't be able to fight at your full strength. Don't you just hate when you get sick?! It's too bad though. Since I'm not a human I don't get sick. Now who has the advantage?!" Envy teased.

Edward's face went blood red and his teeth clenched together. So, Envy did know that he was sick. "You stay away from brother!" Envy gasped as Alphonse slammed his hands together and knocked Envy back. The kid was fast that was for sure. He clapped his hands once more and split the cart in two pieces. Dust flew into the air and passengers in the other cart began screaming. Al picked up his brother and began running away from Envy.

"Al what are you doing?! Get Envy while he isn't looking!"

"No! We have to get you away from him! It looks like he's trying to kill you! Let's get off the train so that the passengers won't get injured!" Alphonse explained as he jumped from the train. They were now standing in the open field Edward saw before.

"My, what do we have here?" Someone hissed with a disturbed laugh. This voice was new. But still, they had heard it before.

"Can I eat him Lust? Can I? Can I please?!" Another one yelled, begging for flesh. His voice was very skittish and nervous. Two figures appeared from the thick smoke that still lingered the air. It was Lust and Gluttony.

"Darn! They're all here!" Edward snapped. He was now shaking and his vision was blurry.

Edward watched as Envy appeared beside them. They were now cornered. Lust extended her fingers. Alphonse gasped as she grinned and slowly walked towards them.

"This world has been connected. Tied to the darkness. Soon to be completely eclipsed..." She began to speak. Alphonse and Edward could only stare at her as she grew closer to them.

"There is so very much to learn yet you two understand so little." Envy grinned and followed behind her. "A meaningless effort…and…" Lust's voice died. A man with gray hair on his chin along with yellow eyes appeared from a dark void. Behind him…was Dante.

Edward felt his heart stop. She was grinning and looking at the terrified brothers, "One who knows nothing can understand nothing."

Destiny Islands (Night) ~

Sora held his Keyblade tightly in his hands as he wandered outside. "Oh man—I can't believe I got separated from him! This is just great this Heartless Sweepers job thing isn't working!" He looked around and paused as he heard footsteps behind him. Sweat poured down his face and his body began shaking and before he could even look behind him he felt a strong hand grab his shoulder. He screamed but then it was covered with playful laughter. His friend, Riku, was laughing with his Keyblade in hand.

"Good one Riku—that was so funny! Don't worry I'll get you back for that." He pouted, sarcastically.

Riku rolled his eyes and smiled, "Oh come on Sora! I was just joking with you. Lighten up! Besides you did the same thing to me last night!"

"Hey! But you knew I was there!" Sora whined. He summoned his Keyblade away and shook his head, "Man, these heartless are starting to be a pain in the butt. I don't remember there being this many from before."

"I know." Riku said with a serious tone. "I knew that once we defeated Xehanort's Heartless and Xemnas that there would still be some heartless around. But not like this. It's getting out of hand. We might just need Mickey's help after all." he sighed.

Sora grew a worried look on his face, one like never before. He didn't want to lose the Islands again...not like this.

"Well what should we do now…" Sora asked putting his hands behind his head and turning to a worried Riku.

Riku looked down at him and scratched his head, suddenly his face fell pale. "Oh no…"

"What?"

"We have a test tomorrow! And we haven't studied!"

"AH! That's right!" Sora yelled, "I can't fail this one! Last time I took a test I fell asleep! And the Teacher gave me an F-! AAAHHH!"

Riku and Sora ran down the dirt road and took off in the direction to Kairi's house, "Sora! You always fall asleep during tests!"

"I do not!"

~ Destiny Islands (Night) Kairi's House

Sitting in her room, Kairi was reading a book. She had to prepare for her English test coming up and so she could help Sora and Riku catch up on what they missed. Besides, she was the only one out of all of her friends that really had the time to study. She put down her book and stepped over to her bedroom window. The night sky seemed so beautiful tonight.

She sighed thinking to herself, "Sora and Riku still aren't back yet!" She wished that they would all settle down for once. Always fighting and traveling. She knew that's what Sora and Sienna lived for but everyone needs a break every once and a while.

"I'll go take a walk then." She suggested to herself. She stood up and slipped on her shoes. Just as she took her first steps toward the door, a sharp pain struck her heart. She groaned in pain. She had felt that pain before. Right before Destiny Islands had disappeared. Once the pain vanished from her heart she ran to the window and looked up at the sky. She could only stare as she saw a strange star flashing purple and red.

Something bad was about to occur…
