I don't own either Naruto or fma. Just trying to write something based on my imagination

"Oi Kakashi... how much longer will this take?" Obito said, as he was panting.

They travelled few miles after deciding that they will go to the Northern Wall of Briggs. Even though Sakura healed him, Obito was in no shape to travel by foot. He was too damaged by the earlier battle against Madara and Kaguya.

"Looks like we're almost there, Obito" said Kakashi. He too was tired from the long walk.

"Let's rest here for a while,Sensei and Obito-san" Sakura said as she sat down on the patch of soft ice beside her.

"Okay, I'm gonna refuel my chakra" Obito said as he lay down to buzz off for some time.

"Looks like it will take us longer than we thought to reach there"Kakashi sighed as he put his hand behind his said.

Meanwhile in Amestris...

The train they took slowed down to stop at a station as they neared Central City.

The duo was exchanging information from the Elric brothers throughout the journey. Ling was also listening keenly as he was much interested in Sasuke's eyes.

"Seems like we're almost there." Al said as he removed the suitcase from below their seats.

"I know that Al, you don't need to remind me"Edward said as he was still fuming. Naruto broke into laughter when Ling said that Edward was the Fullmetal Alchemist,not Al.

Few minutes later, they reached the Central, the capital city of Amestris.

"I wonder how Mustang-san will react when we tell about them"Al said to Ed as they were walking on the platform.

"No worries, I'll deal with him when we go there."

Naruto,Sasuke, Ed and Al took a cab to travel to the military headquarters, where Edward works. Tailing them in a cab were Ling and his two ANBU-like bodyguards.

"So this is where you work, its huuu-ge, it is bigger than our Hokage's office"Naruto exclaimed as they walked through the entrance of the building. He had earlier explained to everyone else about their village and its working. Ling and his bodyguards waited in a lane beside the building.

"Sure it is, it is one of the largest in the country" said Al, as he put his behind his head-helm.

"Don't be shocked at this... we've got a lot more things better than these"Ed said as his eyes gleamed with pride.

"Hn..as if I care"Sasuke smirked, which made Ed angry.

"Don't you dare talk that ignorantly, you twat-"

"Guys, don't start a fight here!"Al shouted as he tried to calm things down.

"Well, that's Sasuke" Naruto said.

The quartet walked up flights of stairs and reached Mustang's office.

"Come on Al, introduce them to Mustang-san"Ed said as he was panting.

"Oh, I forgot that I am the Fullmetal Alchemist's brother, not the Fullmetal Alchemist himself"Al said sarcastically as he pushed Ed inside Mustang's office.

"Hey,don't-"

"Oh,hello Fullmetal. Do you have anything to talk with me?"said Mustang as he was reading some case studies.

"Oh it-it's nothing Colonel." "Damn you, Al" Ed answered in a low tone.

"Where is your brother, I don't find him... Ah there he is... who are those people?"Mustang tone changed from casual to serious.

Ed looked behind as Al came in, along with the duo.

"They're people we met at the train station, the blondie is Naruto Uzumaki and the other guy is Sasuke Uchiha" Al said as he introduced them to Mustang.

"Hello, Colonel Mustang, nice to-"

Before he could complete the greetings, Mustang took out a gun from his drawer and pointed it Naruto.

"Erm..what is that thing?!"Naruto asked, bewildered.

"THAT'S A GUN, YOU FOOL! IT SHOOTS BULLETS WHICH KILL PEOPLE! Now Mustang-san, why are you doing this!"Ed said as he was shocked by Mustang's gesture.

"Perhaps you don't know, so called State Alchemist, this is for our country's protection, you may be spies sent by Drachma or even Xing. Don't you know that idiot?" Mustang said angrily.

"They aren't spies, they're-"

"Now shut your mouth as you've done such a great task of introducing spies to our military facility. What else did you tell them, baka?"

"Wait a minute, I don't get it, you think of us as spies and you don't allow him to speak. FYI we aren't spies sent by Drac-whatever or any other country. Listen to your fellow alchemist before you suspect us konoyaru"Naruto said as he was fuming at Mustang's words.

"How dare you call me an idiot" Mustang said as he shot a bullet at Naruto.

There was stun silence for a second.

Ed and Al closed their eyes, terrified as the bullet was fired. Ed, then tried to have a glance towards Naruto as he was about to confirm his worst fears.

Just then, he heard something. It was the sound of the shell that had hit the floor. He then noticed something amazing, it wasn't one- there were two sounds that he heard.

Mustang was in a state of disarray as he had just seen something very unusual.

The bullet was in two pieces on the floor.

"You ought to listen to your comrades sometimes, even though you're not interested, Mustang" said Sasuke in a distasteful tone, as he put his katana back into its case.

"How dare you! How dare you do that?" Mustang fired 3 bullets at Sasuke.

"I've already told that bullets don't work on me"Sasuke said as his right eye transformed into Sharingan and had a grim smile on his face.

He dodged one,blocked one with his blade and lacerated a cut through another with swift strokes of his blade.

"Let's take this outside"Mustang said.

After listening those words, Sasuke's left eye gleamed as he used Rinnegan to transport all of them to a nearby wasteland.

"Is this ok, Mustang?"

Mustang took out a glove from his pocket and he put it on his right hand. It had a symbol of the Alchemy ring on it.

"His power is to-" Ed tried to explain Sasuke about Mustang's power.

"Just shut up, I will find them out myself" Sasuke said.

"Baka, your stubborn nature will kill you during this fight" Ed protested.

"Just told you to shut up"

Ed tried to attack Sasuke as Al and Naruto tried to hold him back. His mumbles were not clear as they covered his mouth.

"Let's start this, I'm raring to go" Mustang said

*CLICK*

Sasuke's collar caught fire as he tried to dodge from the fire attack.

*CLICK CLICK CLICK*

Mustang shot multiple flames at Sasuke, who elegantly dodged all of them.

So his alchemy is to vary oxygen density of air at various places and uses that glove to start the fire. Hn, very impressive... Mustang.

Sasuke leaped away from his flame and uttered-

FIRE STYLE: FIREBALL JUTSU

A ball of fire emerged from Sasuke's mouth as he directed it towards Mustang. He leapt away from the attack. But, he didn't think about Sasuke's next move.

There was a high concentration of electricity in his left hand and the sound was reminiscent to that of chirping of many birds. Al and Ed looked in disarray as they that.

CHIDORI

Sasuke charged towards Mustang with the electricity in his hand.

"This guy might be someone I used to know" a deep voice said.

Sasuke sent his left hand towards a hapless Mustang. There was a huge puff of dust.

Just when the smoke cleared, they noticed something amazing.

Mustang was on the ground as he was sweating profusely. Sasuke's left hand was held by a man the duo has never seen. Sasuke's move was broken down.

"Darn it, old man. He was about to have a hole in his chest."

"Like I can let that happen to him."

"King Bradley" the Elrics said in unison.

"I have already told you, Mustang. Don't fight with anyone unless it's necessary. Let's talk to them and find out what they really need."

"I don't need to talk to you, come Naruto, let's go somewhere else"

"My comrade acted hastily. Forgive him. Come with me to my office."

He's just as stubborn as that guy.

Mustang was helped to his feet by the Elrics. He and the quartet followed Bradley to the military headquarters.

IN THE NORTH:

"Come on Obito, wake up. We got to go"

"Woah, what just happened?"

"Nothing, you just woke up. Maybe you had a bad dream. It's getting dark. We can't rest any a move"

"Okay"

"Let's get going"
