Any many cases there are things beyond comprehension, and sometimes these things are so incredible that most people don't believe that it is true. One of these worlds is main of entirely pirates and another of wizards. But what happens when the justice system of One Piece meets the one in Fairy Tail.

Marine Headquarters:

A tall and light-skinned man was walking down the corridor while flexing his shoulders in pain a permanent scowl etched on his face, this was Admiral Akainu one of the more powerful members of the marines. It had only been 3 short days since the Whitebeard war had concluded, and although he wouldn't admit it, Whitebeards punches hurt like hell. However as he was walking down the steps he bumped into an unusually tall man with a bright yellow suit on, a fair amount of wrinkles on his face and a thin beard.

"Oooohh Sakazuki, what have you been uuupp tooo", he said in a lazy drawl.

Akainu then looked towards him as his scowl somewhat lessened before you looks towards the tall man, " Kizaru your looking well as usual, but I'm curious aren't you supposed to be heading towards the meeting with Sengoku.

The now named Kizaru then looks towards him with a lazed smile on his face before it turned into one of confusion.

"Oooohhhh so thats what the meeting was aabooout, he said lazily. "Too be honest I just skimmed it".

Akainu was going to respond to his laziness before another figure emerged that made his scowl return full force. Kizaru turned towards the direction he was looking at before smiling at what he saw.

"Helllooooo Kuzan".

The man known as Admiral Kuzan was wearing the same coat as the others only with a white tux and blue shirt underneath, his tanned skin and curly hair was even further framed by the bored expresion he had on his face.

"Hello Kizaru are you and Bakainu here for the meeting as well", he said with a dull look on his face.

Akainu was livid at the nickname his "friend" gave him but decided to let it go for now, " Yes Aokiji we where called for the same reason as you", Akainu said once again giving a serious expression. "According to Sengoku it is an emergency of the highest order".

At this statement both Admirals paled knowing that it must be really urgent if all three admirals were called. Without saying another word all three of the Marines powerhouses then walked towards the meeting room and opened the door preparing for the worst. However, as they walked inside they noticed several more people then usual. First there was a tall man with an incredibly long next with stiches running down it, and two horns atop his head. This was Gecko Moriah a member of the shichibukai.

Next was an equally tall man with a panda like suit on along with a pair of glasses, and a bible in between his gloved hands, this was Bartholmeo "Tyrant" Kuma.

Then there was a pale skinned woman with a revealing pink dress on, a large bust, and long black hair with a snake right behind her. This was Boa "Pirate Empress" Hancock.

Leaning against his chair is a man carrying a hat with a single feather a cross around his neck and a large black sword strapped to his back, with piercing yellow eyes. This was Dracule"Hawk Eyes" Mihawk.

Sitting in chains were 2 men currently chained togethor, one was a man with black hair, a golden hook on his left hand and a fur coat over his back, this was Crocodile, otherwise known as Mr.0.

The other chained man, didn't look like a man at all but was covered in blue skin with red gill like markings on his neck and pointed lower teeth, this was "Knight of the Sea" Jinbei.

And finally was a man with long pink feathers as a scarf short blond hair, red sunglasses, and a devious smile. This was Doflamingo"Sky Demon" Donquixote.

Sitting at the head of the table was a tall muscular man with a long braided beard and an Afro, with a very serious look on his face, this was the Fleet Admiral Sengoku.

Next to him where two men, the first was a man with gray hair and a white navy suit who had a angered look on his face once Akainu walked in, this was Monkey D. Garp.

And at the far right there was a blind man who had on a purple shirt underneath his navy suit along with a cane and short black hair. This was Vice-Admiral Fujitora.

After seeing everyone here Sengoku was quick to quite everyone down, "Now I'm sure that all of you are wondering why i gathered the admirals and the shichibukai, it is quite simple", he said with a grave tone in his voice. "We are hearing reports of a portal that has opened up a few miles of the coast of Marineford, and all the marines who were sent in have yet to return".

"I understand that this is important sir", Akainu said with a serious tone in his voice. "But why call in all of us, surely the Admirals will be enough for this".

"Kishishishi whats wrong Akainu, don't think we will be much help", Gecko Moriah said laughing.

"Why is is that you called us here?" asked Boa Hancock with a Skeptical gaze. "And why did you bring two former Shichibuki with you?"

Sengoku then took a deep breath before explaining, "This is a serious issue that I feel requires a grand meeting between all of us, if any of you want to leave be my guest, but leave you titles as Shichibuki at the door".

At hearing this many of the shichibuki paled, execept for Kuma and Mihawk. However, before Sengoku could explain any further a marine soldier busted through the door breathing heavily.

"Fleet Admiral Sengoku, we have a major problem", the Marine said breathing heavily.

"What is it?"

The soldier then began taking breaths before he said in fear, "The portal began moving sir before 7 creatures emerged from it".

Garp then stepped forward with a serious face, "That can't be all surely you didn't interrupt this meeting because a few animals got loose".

"Its not that sir, its the creatures themselves, they've already destroyed several of our fleets sir, and they took out our giants with ease".

"Well what creatures are they?" Akainu asked angrily. "Whoever decided to attack the marines would pay dearly", he thought.

A roar then cut off Akainu's thoughts, and he was suprised that the whole room began shaking from the force of the war.

"Dragons sir", the Marine said after hearing the roar. "7 dragons have appeared in Marineford".

Authors Note: Hello everybody this is my first fanfic in quite a few years, so I hope that you go easy on me. This is my first crossover and I'm hoping that you guys enjoy it. And for those fairy tail fans they most likely know which 7 dragons these are. The question is, can the Marines handle this threat or will they be wiped out.
