Ramen Goddess: Okay, this is my first Full Metal Alchemist fic so please be kind with your reviews. I don't know how I came up with the idea for this story; it just popped into my head one day. Also, please take into consideration that I'm fairly new to this anime and have only seen between 10 and 20 episodes. However, I think I have a pretty firm grasp on the plot. So without further ado, read on!

Disclaimer: I do not own Full Metal Alchemist, although I wish I did.

Pairings: None.

Warnings: None.

Summary: What do you do when someone pulls a prank on you? You prank them back of course! So what happens when the Flame and Full Metal Alchemist start playing seemingly 'harmless' pranks on one another? Will chaos ensue?

Chapter One: Bad Hair Day!

"Brother, what are you doing?" Al inquired curiously. It was five o'clock in the morning and the two brothers were in the process of sneaking quietly in Colonel Roy Mustang's private bathroom.

Pressing a finger to lips, the elder sibling replied, "Ssh! Quiet Al or you'll end up waking Mustang!"

As they continued to tiptoe over towards where the shower was located, Ed silently pulled back the curtain and reached over to grab the semi-full shampoo bottle. Looking at him rather strangely, Al posed another question.

"What are you planning to do with that, brother?"

"You'll see…" was Ed's response as he pulled a small bottle of unrecognizable hair dye out of his trench coat. Al raised a suspicious eyebrow, yet decided not to question his older brother's plan. He simply just watched as Ed began to pour the unknown liquid into the bottle, which contained the shampoo.

"Okay, now let's get out here before we end up getting caught." Al nodded in agreement as the two made their way out of the bathroom and into Roy's master bedroom. When they reached the door, they heard a noise, which sounded an awful lot like someone moaning. Looking over to the bed in which Roy occupied, they noticed that he was tossing and turning in his sleep, eventually stopping when on his back. Both brothers heaved a great sigh of relief and opened the door, making their way out into the deserted hallway and back to their room.

The following morning…

Roy had woken up about twenty minutes ago and was currently taking a long, hot, refreshing shower. It was a sight that any fan girl would kill to see…literally. However, the Colonel was completely oblivious as to what would happen after he had finished his seemingly innocent shower…

Meanwhile, in Ed and Al's room…

"Heh, I can't wait to see the look on his face when he finds out what was in that bottle!" Ever since he had woken up, Ed couldn't help but laugh; he was really eager to see the look on Roy's face when he looked in the mirror. Al, on the other hand, wasn't so fit to laugh. In fact, he seemed to be more worried than anything.

"You just better hope that he doesn't find out it was you."

"Don't worry; I've got everything under control!" Even though Ed's confidence had skyrocketed, Al's was still grounded.

"I hope so…" With that said, both siblings headed out the door and made their way downstairs and into the dining room where breakfast was being served.

Upon making his way to his office, Roy had no idea that his appearance had been secretly altered a great deal. Oh well, he'll find out sooner rather than later…

When he walked into the office, he spotted Lieutenant Riza Hawkeye standing in her usual position: right beside his desk with a bundle of documents held in her grasp. Looking up, she couldn't believe her eyes. Putting a hand up to her mouth, she stifled a laugh.

Raising an eyebrow, Roy asked, "What's so funny?"

Returning to her previous composure, the young woman's response was simple. "It's nothing, Sir."

"Nothing?" Roy did not seem taken by her reply.

"Yes, Sir."

Deciding not to question any further, Roy strode over to his desk and sat down. As he began to rummage through numerous amounts of paperwork, he turned to Riza.

"Lieutenant, please inform Edward that I would like to speak with him."

"Yes, Sir," and with that said, she exited the room, not once turning to look back at her boss' awkward new look.

In the dining hall…

"Man, this is definitely worth having to put up with Mr. Sarcasm day in and day out!" Ed commented between mouthfuls of French toast. Al, however, just sat beside his brother, occasionally pretending to eat when some of the servants gave him strange looks. It would have made him feel somewhat uncomfortable if he wasn't already used to it.

Suddenly, the door to the room made an irritating creaking noise as someone on the other side pushed it open. When both Ed and Al shifted their gazes to that of the entrance to the hall, they weren't overly surprised to see just who was standing there.

"Hey, Hawkeye! What's up?" So far this morning, Ed's tone had not once lost its cheeriness.

"Colonel Mustang wishes to have a word with you."

Well, so much for cheery…

"W-What about?" Ed asked hesitantly, swallowing the piece of bacon that he had been chewing.

"I was not informed about what he wished to discuss with you. He merely sent me to bring you to him."

"Great. Well I guess I have no choice than to go, now do I?"

Riza nodded in confirmation. "Since the meeting is with the Colonel, I suspect so."

Ed heaved a rather heavy sigh. "Fine, let's go then. I'll see back in the room, okay Al?"

"Sure brother." As he watched his blonde-haired sibling exit the room with Hawkeye, Al couldn't help but think.

I sure hope that Mustang hasn't figured out that it was Brother who pulled that prank on him. I don't want to know what will happen if he's caught…

When both he and Hawkeye stood before the entrance to Roy's office, Ed took a deep breath and prepared himself for the worst.

"Go ahead. Colonel Mustang is expecting you inside."

"Aren't you coming in?" Being alone in a room with Roy usually didn't spell trouble…except on a day like today…

"Not at the moment. I have a few things that I need to get done for the Colonel. I will be in shortly so just go on ahead."

"Okay…" As he pushed the door open, Ed trudged into the room, praying to the Gods that he was not going to get reprimanded for a certain little prank…

"Hello Edward." Said male turned toward the sound of the voice and nearly burst out laughing. However, he managed to hold his tongue so that Roy would not become suspicious.

"Hey," Ed replied simply and then added, "So, you wanted to talk to me about something?" Taking a seat on the couch in front of the Colonel's desk, he shifted his gaze to that of his hands; not wanting to look up for fear that laughter would escape from his mouth.

"Yes I…" Just then, without warning, Ed burst out laughing while Roy gave him a questioning look as he raised one eyebrow.

"What's so funny?"

"Nothing," Ed snickered.

Growing even more serious, Roy would not cease his inquires until he received an honest answer. "Edward, I suggest you tell me what it is that is so funny, otherwise there will be consequences," he practically demanded of the young teen.

The laughing than stopped abruptly. Ed decided that even though it may kill him to say it, his best bet would be to come clean. As much as he disliked Roy, it would only make things worse if he didn't say anything.

Sighing, the blonde-haired alchemist prepared to admit to his actions. "Your hair…" was the first words that slipped from his mouth.

Roy looked confused but decided that a little look never hurt anyone. He opened up the top drawer of his desk and pulled out a hand-held mirror. When he brought it up to his face, he was both shocked and horrified to see the sight before him.

In fact, he was so shocked that the whole building could hear his screams…

"What happened to my hair? It's PINK!" he exclaimed.

"Uh, Sir?"

"Not now Edward! I need to think of a way to get my hair back to the way it was!"

"But Sir!"

"What is it?" he practically yelled. Ed held his hands up as a method of self-defense, hoping that he was not going to be killed for what he was about to say.

"It…" Taking a deep breath and eventually letting it all out, he continued with a newly restored boost of confidence. "…was me…" It was then that Roy's eyes grew as wide as saucers; he couldn't believe what he had just heard.

"You?"

"Yes."

"You did this?"

"I said yes, didn't I?"

As much as Roy wished to strangle the younger male, he managed to keep his cool. "Leave."

"What?" Ed was confused. Why was Roy asking him to leave when it was he who called him here in the first place?

"I said leave. Don't question me."

"Fine, I'm going, I'm going…" Getting up off of the couch, Ed made his way over to the double doors, pulled one of them open and exited the room, closing it behind him. As soon as Roy was sure that he was alone, he began cursing inaudibly under his breath.

"Who or what gave him the right to pull a prank on me, Colonel Roy Mustang? I'm in charge of his well-being while he is staying here, so why would he risk playing tricks on me?" As he continued to ponder reasons on why the prank was set up, an idea popped into his head…an evil idea at that. Roy smirked, mentally applauding himself for coming up with such an ingenious plan…

Ramen Goddess: What is Roy planning? Will Ed be safe? I guess you'll just have to wait for the next chapter to find out! So until next time, please review and tell me your thoughts on this story so far. Does it have potential? Did I do a good job at keeping all of the characters in character? I hope so; I really did try my best. Anyway, I really should end this little rant. Luv ya'll! Ja ne!
