AN: I just read the last chapter of Fullmetal Alchemist, and it was sooo great! I totally cried. I'm so glad to know how it ends, and yet, it's over! What am I supposed to do with my life now? Well, I guess I'll start by finishing this story. Roy makes his debut! I was originally only going to include a few FMA characters, but the cast keeps growing, and I keep coming up with slightly altered Kingdom Hearts inspired designs for them! I gotta try and draw them, and maybe post them on Deviant Art or something. Anyway, Enjoy!

Disclaimer: I wish I owned KH and FMA, but alas, I do not.

Roy Mustang had seen many strange things since leaving his world; magic, heartless and he'd met some strange people too. He'd been relatively open minded and accepting towards every new thing, but the concept of being able to travel through space in a brightly colored rocket was something he was having a hard time wrapping his mind around. So he wasn't surprised at the utter disbelief he felt when he saw said brightly colored rocket ship come hurtling out of the sky.

"What was that?" Roy turned to see the man he'd come to know as Leon walking towards him to get a better view of the cloud of smoke rising over the hills from where the ship had crashed. "Hmmm, don't tell me, they crashed the gummi ship?"

"Good guess," Mustang smirked, the name 'gummi' seemed rather ridiculous to him.

Leon sighed; "I guess we should go see if they're okay…" he started towards the crash site without waiting for a response, and Roy followed.

"WHAT DID YOU DO TO IT?" Cid Highwind was on a warpath, it didn't usually take much to set the guy off, and if nothing else, the things he cared the most about were his gummi ships. So the fact that one of his prized ships was in a mangled mess on the floor of the crystal fissure was not sitting well with him. He'd come running to the crash site as soon as he saw the ship go down and had beaten all of the other townspeople, which meant there were no witnesses if he decided to kill them all.

"DAMMIT! THIS IS WHY I DIDN'T WANT TO LEND IT TO YOU!" he shouted. He took a deep breath to try and calm down. "Who was driving?"

Sora, Ed and Goofy all pointed at Donald almost simultaneously.

"Ah…Wah…HEY!" The duck tried to defend himself but it wasn't really working. "I-I wouldn't have crashed if you hadn't been making such a racket! It's your fault!" Cid turned his attention to the boys who both flinched under his gaze.

"Let it go Cid, we all know you'll have it fixed in a heartbeat anyway." Came a voice from behind them, Sora turned around, he recognized that voice…

"Yuffie!" The ninja girl waved to Sora in response and then looked at the Elric brothers.

"Well, I see you made it back alive after all, guess I lost that bet." She smiled.

"What bet?" Ed stared accusingly at Yuffie.

"Don't worry about it, it doesn't concern you." Yuffie smiled.

"Funny, 'cause it sounds like it does!" Ed glared at the girl but she ignored him and instead went to give Sora a hug.

"Long time, no see! How ya been?" she asked.

"Uh, good, I guess." Was Sora's response.

Yuffie's smile disappeared and she looked at him seriously, "You're worried about those heartless aren't you?" Sora nodded, "Yeah, it's troublesome that they're so much stronger than-"

"Wait, what was that?" Sora interrupted. "I thought they were stronger, but, I was really hoping I was just imagining things…"

Yuffie looked at him confused, and then looked at the Elrics and then at Donald and Goofy. "Didn't you explain?"

"Like I actually know what's going on." Was Ed's response.

Yuffie smirked, "Shortie." She mumbled under her breath.

"GAH, WHAT DID YOU SAY?" Ed screamed.

Sora and Yuffie started laughing together, "It's fun isn't it?" she asked.

"Hilarious!" Sora answered.

"ACK! GROW UP!" Ed fumed, but it only made the pair laugh more.

"Well, I guess we were worried for nothing," came a new voice from behind the group. Sora turned around, Leon was coming towards him with a man he didn't recognize. The stranger was tall with dark eyes and black hair. He wore a short blue jacket over his clothes that had some badges and tassels on it like a military coat. He wore white gloves with the same type of circle diagrams that were on the Elrics' keyblades. Must be a friend of theirs Sora thought.

Leon examined the Elric brothers, "Yuffie, you owe me 500 munny." He said calmly. Yuffie mumbled something under her breath about hoping he'd forget.

Leon looked at Sora, he looked tired, like he hadn't had a good night's sleep in a while. Sora swallowed hard, exactly what were they getting into.

Leon gestured for the group to follow him. Everyone complied except for Cid who was still mourning over his poor gummi ship.

"Let's go," said Leon, "the King's waiting."

AN: Dang, another short chapter. Sorry, they'll get longer as the story picks up. Also, don't be shy, leave reviews! I want to know what you all think. What's good, what's bad, what needs to be changed, any suggestions are welcome. Hope you liked it!
