Hi everyone, after seeing many One Piece/Fairy Tail Crossover fics I had the idea of write my own story, this is going to be my first fic so don't be too cruel if it's not good.

My story takes place when Ace fought with Blackbeard(Marshall D Teach)

I don't own One piece or Fairy Tail

Chapter 1:Sun VS Darkness

The Blackbeard pirates were having a lot of work dealing with Ace due to his Logia abilities, Auge's bullets just passed through Ace's body and the entire building that Burgass threw him was easily destroyed.

Seeing this situation Marshall yells them "Auge, Burgass , you two stay out of this!. You're still no match for him!"

Both of them regrouped with Marshall obeying his orders and Burgass tell him"Sorry boss"

Suddenly, Ace yelled "Hiken!" and the hole crew (mainly Marshall) were hit by a huge wave of fire. When Ace approached to them, he saw that Marshall was yelling in extreme pain while his nakamas were trying to turn off the flames in his body.

"Stop it!, all of you stay back" yelled Marshall when he was trying to get up. Ace could see that Marshall was breathing heavily but suddenly those paintings transformed into a laugh.

When he finally stood up he smirked to Ace and told him "I see Ace, so you wanna kill me. I know that I betrayed the crew when I killed a Nakama, but you have to understand that he found the devil fruit that I wanted, I had no choice!

Ace just stood firm, no paying attention to his words.

"Zehahahaha! Very well if you don't want to be my nakama then I'll beat you with my new powers, Take a good look!"

Suddenly dark clouds began to surround Marshall, when he was completely surrounded by those clouds he laughs again a says proudly "I'm…DARKNESS!"

Ace rises an eyebrow and asks him "Darkness?"

"That's right commander Ace, this fruit it's extremely rare even for the logias, there's no way I'm gonna lose to you!"

Ace answered with a smirk and told him "Hmph, as you like"

"I'll let you taste a little of this powerful fruit, look around you" then Marshall concentrates some darkness on his right hand and then hits the ground with it, a huge dark cloud covered the hole ground all the village and in a matter of seconds the village was completely gone.

"The Gravity of the darkness allows me to absorb anything by destroy it, now I'll show you what happened to the village, LIBERATION!"

Again, dark clouds came out of Marshall and began to form a circle over his head, then massive quantity of wood, piece of glasses, and other things came out of the darkness revealing that the hole village was completely destroyed.

"Zehahahaha!, do you get it now Ace? There's no way that you can…huh?"Marshall was interrupted when he saw some fireflies-like balls around him.

Ace was with both of his hands up and his hat covering his eyes "Hotarubi" he said, and suddenly he yells "HIDARUMA!"

Once he yelled that, all the fireflies around Marshall turned in to flames, burning him over his hole body, again Marshall was in the floor yelling in pain while the flames were over his body.

"I understand very well the great power of the darkness" Ace told him "But this is quite strange… if you really are a Logia type you should be able to dodge an attack like this, are you sure that it's not a Paramecia type?"

Dark clouds surrounded Marshall's torso in order to turn off the flames, when he got on his feet he yells "No it's not, my ability of darkness allows me to absorb anything Fire, Bullets, Lighting, Swords, even the pain! I can't dodge attacks like the rest of you do, my body takes more pain than a normal human!"

'Then why he would want such ability if it has such weakness?' Ace thought.

"But!" he suddenly said "In exchange of that I'm able to overcome to the others devil fruit abilities, and that's why I'm able to do this!" he rises his left hand and point it towards Ace "KUROUZO"

Dark clouds appeared from his hand and ran towards Ace surrounding him, Ace felt like if he was being dragged towards Marshall, but what really surprised him was that Marshall grabbed him by one of his shoulders, he was touching him!

Marshall smirked at his reaction and punchs him right in the stomach and sends him several meters away, "Zehahahaha!, what do you think Ace?, I bet that it's been a long time since someone punched you"

Ace was really surprised by that ability of Marshall, 'This is going to be tougher than I thought' he murmured to himself, but when he was trying to get up…

"KUROUZO" again, Ace was being dragged towards Marshall but he wasn't going to do that mistake twice, his arms turned into flames and he yelled "Shinka Shiranui!" from Ace's arms , two lances of fire were launched towards Marshall.

Marshall didn't have time to dodge the attack and the lances pierced his torso, incredibly and despite feeling a horrible pain Marshall didn't fall to the ground, instead of that he was able to smash Ace's neck with an enormous strength and send him flying to a house(at least what remained of the house).

"Damn it, he almost broke my neck" Ace said while he was rubbing his neck.

Marshall managed to take off the fire lances from his body and got back to his feet (again) and starts to laugh.

Seeing this as an opening Ace quickly crossed two of his fingers in a "+" like form and yelled "Juujika!", a beam of fire was launched from Ace's fingers right towards Marshall, but he just remained firm with a smirk on his face, once that the beam hit Marshall, a explosion covered him completely, but when the smoke got clear, Marshall was still there with no damage.

The fight continued by several minutes, when it reached a point were Ace was in the ground breathing heavily, and Marshall was on his feet but he was also panting.

Marshall laughs again "ZEHAHAHAHA!, Wonderful Ace!, really wonderful!, your power it's truly amazing, it would be a shame that so much power ends with the marines(Marshall was planning to capture Ace to give him to the marine), I'll ask you one more time, be my nakama!, just think about a far we can go if we work together!"

Ace was trying to get up but he stops for a second, then he looks at Marshall and tells him "Sorry, but if I become your nakama I'll be betraying in all that I believe, I definitely don't wanna live with any regrets in my life, did you understand me Idiot?"

For a second, Marshall smirk disappeared, he was a little disappointed at that answer, but his' smirk comes back and tells him "Very well Commander Ace, if that's what you want then I'll defeat you right now" A huge tornado of black clouds surrounded to Marshall "Die for the power of the darkness!"

Ace finally stood up and decided to use all his strength (or what remained of it) in one attack "DAI ENKAI!"

Suddenly, under Ace's feet, a huge amount of fire was forming, and then all that fire surrounded his right punch creating a huge sphere of light around his body "ENTEI!".

Marshall was surprised that Ace still had that kind of strength despite being fighting with him for several minutes. "The Sun or the Darkness, which one is the strongest?"

Ace smirked at this question "Why don't you come here , and find it out by yourself?"

Both fighters jumped towards each other while they were yelling their war cries

When the attacks collided, a huge explosion of Light and Darkness could be seen in the hole island and even from the sea.

Marshall knew that he had won the battle, so he just waited that all the smoke would clear "Haa…haa…that was… haa… haa...harder than…haa…haa…I thought…haa…".When the smoke began to disappear Marshall smirked and said "But at least, I'll be able catch him".

Once that all the smoke was completely gone, the only thing that he found of Ace was his hat, Marshall was completely shocked "WHA…WHAT?, WHAT THE HELL HAPPENNED?, WHERE IS HE?,HE COULDN'T ESCAPE FROM THAT ATTACK!"

The Blackbeard pirates appeared, surprised from all the destruction, but Burgas notices that his captain is surprised by something "Hey boss what happened?" Auge noticed this as well but he ask from someone else "Where's Hiken no Ace?".

Marshall recovered from the shock and tells them "I don't know, looks like he got away, hurry up and find him he couldn't have gone far!"

"Yes sir!" all the crew members answered and began to search for Ace. However Marshall didn't know that no matter how much he searchs for him he was never going to find him…

"Whe… where am I?" Ace asked while he was opening his eyes but all that he can see is darkness and more darkness "Am I dead?" he wondered, suddenly he could see a that the darkness was disappearing revealing a blue sky with a morning sun.

Then, Ace could feel something else(or not feel in this case), and was that his feet weren't touching the ground, he began to sweat nervously and when he gathered enough courage to look down he saw that he was over a city…IN THE MID OF THE AIR!

His eyes went wide and his mouth opened (in a comical way) "YOU GOT TO BE KIDDING MEEEEEEEEEEEEEEEEEEEEEE…!" Ace yelled before start to fall and fall and fall and…(well you got the idea).

And…done the first chapter, I hope you liked it, reviews are really appreciate it
