Disclaimer: I don't own Kingdom hearts/Legend of Korra/Fullmetal alchemist. They all belong to their owners; Nickelodeon and Square Enix. I also added a little bit of the FMA broken angel game train sequence in this story. Enjoy! ; P

P.S: This story is my inspiration of Fullmetal Kingdom: Disc 1 and my theme song is inspired by Zanpaktuo to the heart.

Last time: Sora and his friends bumped into the Elric brothers then asked about Alchemy meanwhile a woman named Korra called her friends, Mako and Bolin to know where they are. After a while of explaining, Sora and the others finally understand alchemy and the ways of this strange world.

Chapter 2: First use of Alchemy part 2

"So that's alchemy, huh?" Sora wondered, "So cool!" Riku sighed while Kairi giggled as Sora looked amazed at the whole alchemy thing. Al scratched his metal head, "Hey, would you all like to come to HQ to help you find a place to stay while you find your way back home?" Kairi bowed, "Thank you! We'd love to!" "Yeah, we could be friends or something, right?" Ed looked at the spikey head then said, "Sure. Why not." "Cool! Just one condition, don't call me weak! Ok?" "You don't call me short; I won't call you weak, Ok?" The two glared at each other as Al tried to break them up. Donald looked at the building and asked, "Is that it there?" Ed stopped his glaring and turned to the duck. "Yep! That's it."

Inside HQ...

They walked down the halls, into the office, where they saw a woman in a blue uniform. She turned and stared at the newcomers, then spoke to Ed, "Fullmetal, you know the rules! No visitors allowed here!" "Come on, lieutenant Hawkeye, they just want to find a place to stay till they find a way to get back home. Can they here to see the Colonel, please?" Riza sighed as she unwillingly accepted them to stay for a while. "Ok, I'll inform the colonel that their here."

After a while…

Lieutenant Hawkeye came out of the doors to find the group sitting in the corner, waiting. She walked towards them to say the good news. "He said that he accepts." They all had smiles on their faces, as if all yelling out 'Yes'. "You! The spikey one." Sora looked up and said, "My name is Sora, ma'am. And yes?" "I want you to fetch that kettle over there and put boiling water in it." Sora then put his hand together and bowed. He went over to kettle then touched it and suddenly, a flash of light and sparks of blue electricity appeared and when they stopped, the kettle was boiling.

"…"

All were shocked, then Ed spoke, "Hey Sora, call me crazy, but I think you just used alchemy!" "But he didn't use a transmutation circle, brother" Riza looked closely at the boy then went back in to inform the colonel.

Riza then came out and told to come in that the colonel want to see them. They walked in to the colonel and listened. "Good evening, I am Colonel Roy Mustang and I have heard from my lieutenant that you, young lad, have the same alchemy powers as our newest alchemist and the Elric brothers."

Ed and Al looked at each other then asked, "Newest alchemist? I didn't know somebody joined." "You will see her in a minute. Now, as for you, Sora, I would like to recruit you as a state alchemist!" Sora wanted to be one! "YEAH! I do!" Riku put his hand on his friends shoulder. "Sora, think about this!" "Don't worry guys, I'll be fine. Really." "Ok." Then it was decided that Sora should become a state alchemist!

After a few months of training…

Sora came in the office wearing a coat like Ed's only brown with a Keyblade sign on the back. He had alchemy gloves like Roy's. Roy looked impressed then said, "Alright, Now that you're a state alchemist, your alchemist name will be the Light alchemist and you will be teamed up with the Elric brothers and you will be staying at lieutenant Hawkeye's home. You also will be taking care of your friends while they stay with Major Armstrong. Understood?" They saluted to the colonel, "YES SIR!" "Good! Also, I have another teammate for you. Welcome, Korra, the Elemental alchemist." A woman came in wearing the same coat but blue instead and with alchemy gloves and alchemy boots. The left glove's transmutation circle is blue, meaning water, the right glove's circle is red, meaning fire, the left boot's circle is green, meaning Earth and the right boot's circle is white, meaning air. She smiled at her new teammates and said, "Well, this will be fun! I can't wait to beat up the weakling and the shorty."

"WHO'RE YOU CALLIN SO WEAK THEY CAN'T EVEN LIFT A PILLOW?!"

"WHO'RE YOU CALLIN THE WORLD RECORD BREAKER FOR BEING SO SHORT?!"

"Oh, looks like I've hit a nerve for you two."

Ed had the maddest face on him, ever. "Shut up!" Sora agreed, "Yeah!"

As the three of them were at each other's throats, Roy told them that their first mission was in a small town filled with little black creatures, as Sora identified them as Heartless. He explained everything to them; about other worlds, the Heartless eating hearts, the Nobodies, the Keyblade and their quest to stop the Darkness. They then caught the train to the town and arrived to find anything there, much to their surprise; the town was deserted with nothing but empty houses.

A nearby phone rang and Ed picked it up and then hangs up, telling them that it was Roy saying that the town information they got was a week late so they had to come back.

On the train back, they were waiting for the train to get back to Central. Then the train slowed down a bit and then the speaker came on with an announcement; "Attention all passengers! This train is now under the control of the People's Easton revolution Front!" Al wondered, "People's Easton revolution Front? Sounds like a bunch of names cut and pasted together."

Two men came in, shouting, "Hey, who are you freaks?! Didn't you hear the announcement that this train is now under the control of the Easton Liberation Federation!" " I guess they changed their name since the announcement." Sora looked bored and huffed. Then he realised, "Hey wait, weren't we in a situation like this?" "Yeah, we were."

"Okay, take the goods from the lady and the armour; I'll take from the weakling and the shorty!" Sora and Ed had anime anger marks then said, "What did you call me?!" "Who are you calling 'shorty'?!" "Ha! You! Who else is there? Weak and shorty!"

Oh no!

(Clap) "WHO'RE YOU CALLIN WORLD'S SHORTEST SHORTY?!"

(Clap) "WHO'RE YOU CALLIN WEAKER THAN A PIECE OF A STICK?!"

The two alchemists punched the men out of the train, when one more man walked in and saw them and tried to get ready to fight but Korra clapped her hands and her left boot's circle glowed and then she swung her arm around then the floor moved and pushed the third man out of the train.

Ed saw the napkin that the man dropped and it had a transmutation circle on it. "Looks like we've got alchemists on our hands." They then agreed that Korra and Al would check inside the train, while Ed and Sora would check on the roof. "LET'S GO!"

They fought all the way through the train and then they caught up with each other and found a man on the roof, he had an automail left arm and a military uniform.

Ed then spoke to him, "Okay pal, who are yo- wait that uniform and badge. Are you a former military policeman?" the man said nothing. "Wait brother that badge means 'senior colonel'. You don't think it's…" "Hey, pal, you wouldn't happen to be called 'Genz', would ya?"

Genz then smirked and laughed, "Yes, I am! The armour-piercing alchemist and strongest in the military! Wait, you're not Fullmetal, Element and light, are ya?"

"Wow! Only a few hours of being a state alchemist and I'm already that famous!"

"Hahahaha! Yes! I've waited for this! Alright, Fullmetal, It's you and me! Your right arm and my left arm and see who really should deserve the name 'Fullmetal'."

They fought for a while, Genz tried to crush Ed's arm but Sora and Korra transmuted Genz's arm into a golf club and then Sora kicked him in the stomach which pushed him away.

"No way! I CAN'T LOOSE!" "Looks like you're beginning to understand that I'm way out of your league!" Sora laughed at Ed comment and Korra just snickered and said, "Strongest in the military? I think the Flame alchemist is stronger." Then Sora said, "This guy just had it easy all his life you know no real challenges." Genz growled and shouted, "I'll show you, little weaklings!" Sora twitched at that last part. "See you later, Snotty shorty!" Ed twitched at that also. (Sora & Ed: clap) "WHO'RE YOU CALLIN A WEAK WEAKLING?!" "WHO'RE YOU CALLIN SNOT NOSED SHORTY?!" They both transmuted a canon and shot at Genz but he jumped out of the way and the cannonball missed and went in the tunnel and caused a cave in. They all looked shocked then Al sighed and said, "Oh man."

"Our bad."
