Chapter 1
Erin's New Mission
My first One Piece fic and my second Fullmetal Alchemist crossover. Those of you who read "Alchemists and Monsters," I just want to let you know that Erin is a multiuniverse OC. While she may be Ed's granddaughter in one fic, in this one, she is the gender-swapped version of Ed himself.
I do not own One Piece or Fullmetal Alchemist. Just Erin.
"Ugh~! Why couldn't this 'Cocoyashi Village' be in Xing or Amestris? Then I wouldn't be feeling like crap right now." Groaned a girl who was half in a small boat and half in the sea.
She had blond hair that reached the middle of her shoulders, braided and with an 'antenna' over the center of her forehead and between parted sharp bangs. She was dressed in a black tank top with a black undercoat over it with a white strip in the middle. She wore black pants and black boots. She also had a red trench coat with the Flamel symbol on the back in black and had white gloves on her hands. In her pants pocket was a silver pocket watch with a lion insignia on the cover.
This was the Fullmetal Alchemist: Erin Elric. According to Amestirian State Records, she is the youngest person to ever join the military as well as the first female State Alchemist. She is also a prodigy with a high I.Q. and the ability to perform alchemy without transmutation circles.
"Sister! I told you to take those pills to prevent seasickness!" griped a giant suit of armor holding onto the girl so that she didn't fall over.
This was Erin's younger brother, Alphonse Elric. No one but those close to Erin's superior, Colonel Mustang, knew the truth of why he wore armor.
"I've been on boats before, Al. Not once was I seasick-ugh-till now." Erin replied, heaving.
"The Colonel told you that the ocean can get choppy."
Erin's eye twitched at the mention of the Colonel. After all, he was the one who gave her the mission.
Flashback—A week ago
"You called, Mustang?" Erin asked bluntly as she entered the Colonel's office.
The black-haired man in front of her looked up from his desk as the Fullmetal Alchemist took a seat on one of the chairs in front of him.
"Fullmetal. I have an interesting mission for you this time."
"Really? Like the last mission and the one before that and so on?" Erin asked sarcastically. "Seriously, Colonel. None of the missions you gave me have been 'interesting' lately."
"Well, is the word 'Fishmen" in your dictionary of interesting?"
This caused Erin to raise her eyebrow.
"Fishmen? You mean, like chimeras?"
"No. Actual Fishmen."
And like that, it was hook, line, and sinker.
"So, what's with this Fishmen thing?"
"I'm glad to have you take up this mission, Fullmetal."
A vein on Erin's forehead became visible as the Colonel continued.
"There has been a…development in a village across the East Blue. For eight years, the village, known as Cocoyashi Village, has been under the iron rule of a Fishman pirate by the name of Arlong. We've been holding back, hoping that the Marines that are in charge of the area would take care of it. But it's been strongly suggested that those water-bound slackers might be in on whatever Arlong is planning. After a few months, I managed to receive permission from the Fuhrer to send a State Alchemist to Cocoyashi Village, expose the Marines there, and take out Arlong and his Fishmen."
"So…why do you want me to do it?"
"Because of your abilities and your record, you are the perfect candidate for this job. Just try not to blow your top. We're already on edge with the Navy. No need to turn this into a war."
"What about Al?"
"He goes with you as always."
"And what happens if I say no?"
"Then you will be court-martialed, stripped of your rank and privileges, and get kicked out of the military. And if that happens…"
"Alright! Alright! I get it! No need to pull that card out."
"Excellent. You and Alphonse will leave tomorrow."
"Why do I get the feeling that I'm gonna regret this?"
She definitely was feeling that she was going to regret it. It doubled when Al had to force her to take the pills to cure her seasickness.
"Remind me to kick Mustang's ass when we get back."
Al sweat-dropped at his elder sister's comment.
"You remember that we're indebted to him, Sister. Anyway, we should be more concerned with this Arlong business. I mean, from what we have learned from the Colonel, these Fishmen are dangerous. Especially when in the water."
"Then we'll just have to stay out of the water. We can't swim, so there's no need to go into the water to fight some Fishmen. If they go under, then we'll just have to use alchemy to bring them back up." Erin answered simply.
Al continued to sweat-drop. When she should be worried, she's the opposite and she was always looking for a fight. He was surprised that Erin wasn't born a boy with the name Edward.
As they continued to talk, an Amestrian soldier approached the pair and spoke.
"Excuse me, Miss Fullmetal Alchemist. We have spotted Cocoyashi Village dead ahead. We will be landing shortly."
"Great. Get us there, a.s.a.p."
"Yes, ma'am." The soldier replied before he headed to the helm to give the alchemist's order.
Erin looked ahead to see a small landmass on the horizon.
Upon setting foot on the island, the Elric Siblings immediately felt the despair that the island had gone under. Looking at the destruction of one of the villages nearby, which the place was upside down and deserted of all life, the siblings became cautious to the Colonel's warning that Arlong was both strong and dangerous.
As they entered Cocoyashi, they were greeted by stares and murmurs.
"Who are those two?"
"Don't know."
"They don't look like Fishmen."
"I think the one in red's a girl."
"Are you sure? It looks like a boy."
"And what about the armored one? Why is he wearing armor like that?"
Erin huffed as she whispered to her brother.
"Jeez. It's like these people never saw an outsider before."
"Sister. Arlong is the reason why no outsider comes here."
"Still, it's a pain that they're acting like this. Let's just find the damned Fishman, kick is ass, and head back to Amestris."
"Amestris? What's that?" A voice spoke from behind.
The Elric's freaked out in surprise at the sudden sound of the voice, which caused them to jump to look behind them. There, standing behind them, was a boy close to Erin's age.
He had a scar under his left eye and black hair. He was wearing a red button-up sleeveless shirt, jean shorts, and sandals. On his head was a straw hat with a red ribbon around the brim.
"Wha! Where the hell did you come from?" Erin yelled in surprise.
The boy, with a blank look on his face, pointed to a palm tree.
"From over there."
The Elric Siblings sweat-dropped at the boy's answer.
"That's not what she meant." Al replied.
Erin sighed in annoyance and turned around.
"Sorry, but we have no time for this."
But it was then that the boy asked, "Hey, how come you're so short."
Al sweat-dropped as his older sister turned toward the boy and began to flail angrily.
"WHO ARE YOU CALLING A PINT-SIZED MIDGIT THAT'S THE SIZE OF A GRAIN OF SAND, YOU BASTARD?"
But to Al's surprise, they boy laughed at the alchemist's outrage.
"Ha-ha, you're funny. Do it again, Shorty!"
It was then that Erin grabbed the boy by his shirt collar and began to throw him.
"I SAID DON'T CALL ME SMALL!"
She then threw the boy across the village, sending the villagers into a state of shock.
But instead of groans of pain, there was laughter coming from the other side of the village.
"Ha-ha, oh man that was hilarious!"
The villagers and Al sweat-dropped at the boy while Erin remained seething with rage. But as the girl planned to go over and beat the boy up, Al placed a hand on her shoulder.
"Sister. Maybe we should just do what we came here to do and not cause a fight."
Though still livid, Erin gave a sigh of defeat.
"You're right, Al. We got more important things to worry about."
She then turned to the villagers.
"Hey. Do any of you guys know where I can find a Fishman named Arlong?"
Immediately, the villagers' looks changed from sweat-dropping at Erin's temper to looks of absolute horror at the siblings. A man with dozens of scars and a pinwheel on his hat approached the siblings.
"Are you crazy or something, kid? Arlong will snap you and your friend into pieces."
It was then that Erin brought out her pocket watch and showed it to the man.
"Where we're from, watches like this one don't just tell the time. They also serve as to verify the identification of State Alchemists."
It was then that the man's eyes widened.
"Th-then you're…?"
"That's right. We're from the Amestrian Military. I am a State Alchemist known as the Fullmetal Alchemist: Erin Elric." Erin then gestured to her brother. "And this is my younger brother, Alphonse."
Upon introductions, they straw hat boy immediately returned to the scene, stars sparkling in his eyes.
"Wow! That sound's cool!"
The Elric's sweat-dropped, but Erin shook her head and returned to her explanation.
"Anyway, I have orders to take out Arlong and free the islands under his iron rule. All I ask is the location of this Fishman and any other information that can help us."
After a few minutes of silence, the man spoke in anger.
"How can we trust you? You may have the silver pocket watch of the Amestrian alchemists, but how can we be sure you're telling the truth."
Sighing, Erin took a few steps back until she was a couple of feet away. She then clapped her hands once and placed them on the ground, a blue electrical light shining. The villagers covered their eyes while they boy watched in amazement. When the light died down, the people saw an elegant fountain where Erin had placed her hands.
"WOW! THAT'S SO COOL!" The boy yelled.
The man, now convinced on Erin's identity, huffed.
"Very well. But we're waiting for news from Arlong Park. You'll have to wait until then. But that doesn't mean we'll trust you. The marines already broken our trust, don't expect us to think differently of the Amestrian Military."
"Fine by me. As long as I can kick Arlong's ass." Erin thought.
After that, the villagers went back to what they were doing. Well…except for the straw hat boy. Annoyed, Erin asked him, "Well? Aren't you gonna go back to your tree."
The boy just smirked.
"Nope. I'm gonna hang out with you guys."
Erin groaned mentally.
"Somewhere in the world, a village is missing its idiot." (1)
Trying to avoid a possible fight, Al then asked a question.
"So…what's your name?"
The boy grinned as he answered the younger Elric.
"My name's Monkey D. Luffy. And I'm gonna be King of the Pirates!"
