Natsu and White…

These two men were battling out in the old ruined city, the pink haired mage was attacking White with his fist of flame. White was delivering blows to Natsu as well, "I'm impressed Dragonslayer I've not seen anyone else keep up with me!".

"Well I don't know if I should be happy by that comment. Knowing that you killed people before you bastard.", he soon unleashed a Fire Breath attack. White jumped back away, in trying to avoid the attack.

The two of them stood in front of each other. Natsu stared with eyes rage and White looked at his eyes, "Hahaha", The assassin began to laugh, but the kind of laugh that someone was enjoying themselves.

Natsu was agitated by the man's actions, "Hey, you jerk why are you laughing at! Do I have something on my face?".

White wave off the boy, "No, I'm sorry. It just that your eyes remind me of a friend of mine.", he told the dragonslayer, "He the same eyes of determination.".

Natsu was surprised by the man's words, "Really a friend? What happen to him?".

The man gave the dragonslayer a shrug, "Don't know was taken from villages a few years ago, to the tower of heaven.", Natsu eyes widen when he heard those words, "He was lucky enough to not get capture. Now, I hear you went and destroyed it along with your brother. That was quite impressive.".

"What that means you know Erza and Jellal!", Natsu yelled at the man, "Erza never mention you or anything.".

White scoffed at his words, "That woman! Don't you dare say that name.":.

"Why? Is there something wrong with her?', Natsu wanted to know the man's beef with his friend, "Did she do something wrong?".

White took off his fur trim coat and hat, "I was know in the tower of heaven, as the White Tiger of Hell",", Natsu felt chilled from his spin, "I had a reputation of killing the guards at that place. For that many feared me except Erza.".

"Why is that so bad?', Natsu asked the assassin, "She was afraid of you.".

"That was the point!", he yelled in frustration, "Just how does someone me not be feared by one single person! It doesn't make any sense!".

"She probably has a reason!", Natsu explained to the man, "If you and her talk maybe.."

"SHUT THE HELL UP!", White screamed at the dragonslayer, "The time of words have ended! I will give you every single bit up of my strength!". The man soon began to grow, his skin grew fur that was white with black stripes, claws grew from his nails, his teeth began to grow into fangs. He had turn into a humanoid tiger creature, "Get ready.".

Natsu was in awe, in what he had witness, "Are you a take over magic user?".

"No", he then appeared before Natsu punched the slayer in gut, "I'm a devil fruit eater." and soon sent him flying in the air.

…

On the ground…

Kuzan and Jinbei were exhausted from stopping the moving castle, "Man this thing wouldn't go down!".

"Yes, even with the combination with my water and your ice. Thing has some strong legs.", Jinbei told wizard saint. But they soon saw the structure charging up it's beam, "Oh, no it going to release it attack!".

As he finished his words Kuzan went up to the air, "I"ll block the attack with Ice!".

"Kuzan, are you crazy!?', the fishman told the the iceman, "You'll die!".

"I have to stop it or else other people will die!", Kuzan soon released his ice, "Ice Age!". Kuzan soon created a giant ice ball. The structure fired it beam and collided with the ice ball. The giant ball began to crack, Kuzan continue to create more ice.

"Kuzan!", he look to see it was airship of his guild up in the air, "Don't worry, we here to help!".

Kuzan couldn't help but smiled at his fellow guild members, "Thanks guys!", the ship came at the direction where the beams was and absorb some of the blast.

The dragonslayer was up in the air, he was in shocked what he had heard, "That impossible. Devil fruits only existed in Ace's world! How could he have one?". Natsu soon recovered and stared down where White was and saw he was there.

He soon swung it down at Natsu. The dragonslayer received an electrical shock from the attack, "AAhhh!". White soon garb Natsu by his leg and flings him to the ground, causing the ground to crack from the impact.

White gracefully lands on his feet and stares at Natsu, "Is that all you can do boy? I was expecting more!".

The dragonslayer soon picked himself from the ground, he was panting heavily and barely able to stand, "Don't worry punk. I ain't done yet!", he ignited his fist on fire, "I'm all fired up now!'. He soon pounced at the tiger man, he flung his fist at his gut. White let out a grunt, Natsu smiled at delivering damaged, but the Tiger man gave smiled, his hand had block Natsu attack.

"Damn it! I can get out this grip, His tail is...His tail", Natsu soon had an idea, he open his mouth and bit White's tail.

Crack….

"Ahhh!", White soon threw Natsu somewhere else and began to pet where the dragonslayer had bit him, "What in the world kid why did you bit my tail?'.

"You were choking me first you jerk!", Natsu responded as he got up where white had thrown him, "And your fur taste discussing!".

A tick mark appeared on White's head, "Screw you man I brush my hair everyday and used the best conditioner. I make sure my fur is the best their is!".

Natsu was shocked and began to laugh at his words, "Really mean? You groom yourselves? Man, I expect Happy to do that, but not you man!".

Tiger eyes began to twitch at the boy comment, but soon began to chuckle, "Ha, I guess your right this pretty funny.".

Natsu looked at the man, "Hey, I got to say why are you with those guys. You seem kind of a nice guy if you asked me.".

"What?", White was shocked by his words and soon let out a sigh, "Let just say that I have a debt I have to pay off. But, let end this chit chat. Once again kid I want you to come at me the best you can. If you don't. I will kill you!".

Natsu soon pounded his fist together and ignited them, "Okay, I make sure you'll lose and bring down this walking piece of junk.".

Erza had defeated Nightmare, Jellal saw flames in the background and he turned to Erza, "Erza, I need to go where Natsu is he's in trouble. Only I can help him.".

Erza looked at Jellal, "Is he fighting White?', the bluenette nodded, "He was there with us, at the tower of heaven, right?".

"Yes, was the same as us.", Jellal began to explain to his friend, "He was known to act violent and would kill guards constantly. He was soon sent to solitary confinement, since the guards were too afraid of killing him. But, soon a man came into Tower and took him away and gave him a fruit ".

Erza eyes widen from his words, "That fruit would happen to be a Devil Fruit?", Jellal looked at the red haired woman, and gave a nodded, "What that impossible! Those only exist in Ace's world the grand line! There no way.".

"Yes, impossible but what I can remember now is that, Metro is the one who has them", Jellal explain to Erza, "I do not now how they have him. But, I do know that Natsu will have a hard time in fighting. I must go!". He soon ran where Natsu was fighting, Erza only stan d and watched as Jellal ran.
