Disclaimer:I don't own One Piece

A/N:Thank you for feedback and welcome to new readers! My last chapter was sent early in a morning with a sinus ridden head…after practically no sleep due to an annoying cold I decided to write some more as I can't be bothered to do anything else right now! So, this has come about faster than I anticipated and may be a bit pants compared to my last chapter but I hope you can forgive me.

Body Swap

Chapter 4

Their lunch time together was not far from their usual experiences, good food and commotion, although with a few minor differences. Luffy for one suddenly realised the disadvantages to Franky's body when he could not sneak more food into his mouth. When he decided to try to use one of Franky's fists, which came out of his body via a chain it was difficult to control and resulted in food and plates going everywhere. The reaction of his friends was far from amused.

Usopp however found a use for Luffy's extendable arms by agreeing to wrap one around their captain to prevent him from causing any more drama. Although Luffy appeared to maintain his appetite for more food Franky's body was not the same as his own and he watched Usopp eating meat by the mountain full and felt a little jealous. Usopp, unlike his captain, was able to restrain himself a little and made a point to try to teach his captain some manners, by asking for more instead of taking from his friends.

Nami and Zoro remained silent for a majority of the time. An ominous aura surrounded them resulting in some concerning looks and nods between their friends. Sanji placed a plate of healthy food in front of Zoro as much to his dismay. The cook argued the importance of keeping Nami's body in shape. A nod of agreement and a threatening stare from said navigator soon told Zoro that he had better eat what was in front of him and not what he would rather have. Although Sanji had produced the same good food for Nami she preferred to tease Zoro by eating the doughnut he wanted right in front of him. Zoro did his best to ignore her actions.

Deciding to break the awkward silence Franky turned to speak with the swordsman, "So bro, I managed to finish making spare weights for you. I put them in the training room". This comment immediately caught the swordsman's attention.

"Great" Zoro grinned, looking forward to trying them out. He needed to work of some steam.

"Um sorry to interrupt" the voice of the navigator caused Zoro to stiffen in irritation, "but you aren't thinking of training when in my body are you?"

Zoro shrugged, "so what if I am? Your body could do with some training" he retorted. The verbal acknowledgement of how weak her body was did not go down well with Nami, her face turning into a frown.

"Moron! Nami's body is explicitly toned and perfect!" Sanji shouted in a threatening tone and still frustrated with the fact he couldn't fight the moss head on equal ground while he was in Nami's body.

Zoro chose to ignore the cook. Instead he finished his meal and headed out the door. He didn't have to put up with any of their crap and decided to go ahead and do what he wanted instead of being told what to do. Besides, training was his thing and if he stopped doing that then what else did he have? It was what he needed to feel himself and in control. After his experience with Nami in the bathroom that morning he needed to reassure him self that he wasn't going to turn into a woman.

"Where are you going?" Nami asked from behind him. Zoro ignored her and kept walking, but this did not dissuade her in the least. He grew more annoyed at how she insisted on following him wherever he went as if he would try to do something dangerous or disgusting with her body.

Nami stood by the hatch as she watched Zoro walk around the training room checking his equipment and approaching two large round metallic shapes in the centre of the room. Given the quality of the finish she could only assume they were the new weights provided by the cyborg. Zoro knelt and studied them closely, running a hand over the metal with a grin appearing on his face. He walked over to a long metal pole and positioned it in the centre of the room, readying himself to add the weights to it.

Nami watched him with arms crossed and a hint of concern on her face. He was planning on trying to lift that with her body? This she had to see.

As predicted, Zoro tried to lift the pole with the added weight and struggled. He tried to breathe through his nose and bent his knees, pulling with all his might, but they would not come even a millimetre off the ground. Nami could not help but snigger as she watched him start to sweat and go red in the face.

Zoro was irritated by his audience and stopped what he was doing. "What's so funny?" he muttered, feeling something he had not felt in a long time, inadequate and weak.

Nami walked over to him and said, "What did you expect? You are in my body after all and if you don't mind I would prefer it if you didn't give me an ulcer"

Zoro gave a "humph" in response and went to try a lighter weight, then another and another until he found one which was light enough for her petite body. Nami sat and watched him sighing at his pig stubborn headedness.

Growing irritated at his back seat expert Zoro demanded that if she thought she could do better then to try it herself. Nami could not help but think how much he really appeared to act like a girl at that moment in time. She shook her head, "no way" she said, she wasn't falling for that one.

Zoro wiped his face with a towel and picked up a small weight by his side then threw it in her direction. Nami shrieked and went to move out of the way of the oncoming missile but Zoro's body instinctively caught it. This action surprised her. She sat staring at the object in her hand.

Zoro grinned and he was pleased to see his body was not letting him down. We walked over to it and pulled Nami up onto her feet, dragging her over to the weights. Deciding to break her in gently he started with a lighter weight that he knew even she could have managed in her own body. He pointed to it and said "my body needs training and exercise" his tone implied she do as he says. Nami ignored him and went to walk away.

"Are you the type of woman who would get in the way of a friend reaching their dream?" Zoro asked using her own tactics against her like she did with him back at Whiskey Peak. His words caused her to stop in her movements. She turned around with an annoyed expression, stormed up to the weights and picked it up with one hand.

The speed in which she picked it up compared to how light the weight was, took Nami by surprise and she struggled to maintain her balance a little. Zoro helped to catch her and she felt small hands on the base of her back and her bicep.

"That one seemed too easy. Try these" Zoro said, adding one weight at a time and instructing Nami to lift each more than once.

Nami was surprised at how light most of the weights appeared to be at first. Although she felt stronger and a little more confident, it was a little disheartening to be forced to recognise the clear difference in ability between her and the swordsman. She always knew how weak she was compared to her friends and how she had to rely on brain power instead of brawn, but it suddenly dawned on her how hard Zoro had to train to get where he was. If he didn't do this religiously then he would have never been able to help them out all those times.

Zoro watched as Nami's expression changed from irritation to one of concentration. She started to sweat as the weights got heavier but didn't give up immediately, which he was surprised about. It was as if she had suddenly gained some determination to see this through and do as he requested. He was secretly impressed with her sudden obedient side and willingness to help his body get stronger. After a period of time Zoro, with Nami's assistance, managed to get the new weights onto the pole.

"Are you sure about this?" Nami asked, feeling the strain already from her work out. She had half the mind to give up but she found herself not wanting to disappoint the man before her for some reason. She put it down to her competitive side.

"Won't know until we try" Zoro was not sure how his body would react to this but he needed to know for his own piece of mind.

Nami positioned herself as he instructed. Zoro placed his hands on her to indicate how to hold her body position. She bent her knees and tried to keep her back straight, ignoring the slight spasm running through her side. Zoro guided her hands to get a good grip on the weight and then stepped back. Nami looked at him and then at the weight. She tried to lift it and failed. The weight came off the ground by less than a centimetre.

"What the hell are these made from?" she thought out loud. Bending over and wiping her forehead. Zoro stood and watched her with a frown on his face.

"Try again" Zoro ordered. Nami looked at him as if to say 'No' but when she caught his concerned expression for some reason she felt obliged to.

This time Nami tried to put her whole might into it and breathed carefully as she lifted the weight. It reached a quarter of the way up her shin. She dropped it and the ground vibrated as she panted over the weight, ready to give up.

"Again" was all Zoro said in response.

Nami looked at him, growing slightly irritated, "I can't!" she snapped.

Zoro wore a fearsome expression and stepped forward "Don't underestimate me" he said with a firm tone, forcing her to remember whose body she was in.

Using her new found anger to her advantage Nami tried once more and managed to get the weight near to her knee. She felt her body resist against the motion and knew she had done too much. It was as if the aching she had been feeling throughout the day increased ten fold. She yelled out and dropped the weight. The weight made a hole in the floor, falling to the deck below and embedding itself deep within the ship. The action caught their friend's attention and she could hear blasphemy from their shipwright.

Nami collapsed to her hands and knees and started to struggle to breathe and wretch slightly. She felt dizzy and her vision blurred, closing the single eye of the man whose body was in her control, she prayed that the pain would subside. If this is what Zoro felt like every day he trained then the guy went up in her estimation. She for one wouldn't want to be doing that again.

Zoro looked from the hole and over to Nami, "Hey are you alright?" he asked with genuine concern.

Nami kept her eyes closed and felt her body heating up, "No" she said with a hint of panic in her voice. She heard the sound of light feet move towards her. A hand placed itself on her back while another on her head.

"I can't move…it hurts so much" Nami felt as if she was going to faint and tried her best to fight it.

"Sorry, I shouldn't have pushed you so far…I forget you aren't used to this like I am" he said. If it had been him he would have been able to control the weight so as not to lose it but he had to admit that Nami's willpower was impressive to have held on for so long even if she lacked control over his strength. He may need to teach her how to meditate and learn to control her mind and body better. But for now he knew it was best to try to help alleviate the muscle spasms running through his body. It needed to do a warm down.

"You need to stand up" Zoro ordered, placing a hand under her arm pit and pulling her up. Nami tried to resist him and argue that she needed to lay down instead but he wouldn't have any of it, "Look I know what is best for my body so just trust me for once!" he snapped. Nami looked at him. She could see a blur of orange and forced herself to blink a few times to adjust her vision.

"Where are we going?" she asked through panted breath.

"To warm down" he replied, placing her arm around his shoulders and a hand around her waist.

"Huh?" Nami was suddenly unimpressed to hear that they had not finished yet but followed him reluctantly. "I seriously don't know how you do this" she muttered. She did not see the small smile from the swordsman. Was she finally beginning to understand what hard work was about and what he had to go through in order to ensure she was safe?

…

Zoro approached the anchor of the ship and gave Nami a sideways nod. She looked at him and said, "You expect us to set anchor here? Out in the middle of no where?"

Zoro nodded, "The best way to warm down and prevent your muscles from cramping up is to swim"

Nami thought about this a little. She had muscle cramp once or twice in her sleep in the past and knew it could be really painful but what she felt right now was insane. She couldn't begin to imagine this pain getting worse. She felt herself go pale. Sighing and muttering at how much he was going to owe her for this she gave some orders to their friends and dropped the anchor.

"Hey why are we stopping?" Luffy demanded to know.

"Nami needs a swim" Zoro replied helping Nami down into the waters below.

"Swim?" you could see the cogs working over drive in their captains head. He looked down at the hands of his new form and a grin appeared on his face. "Hey! I can swim now without getting weak!" he realised with a new found eagerness.

"Does that mean I can to?!" Chopper asked, having identified he was in Sanji's body and following Luffy in a small dance before jumping into the ocean after Nami and Zoro.

Usopp watched from the sidelines with Sanji, both of them suddenly realising the disadvantages to having devil fruit powers.

"Yoohoohoo!" a shout from beside them came as the figure of Kinemon jumped over board after his friends.

Usopp sweat dropped, "does he even realise that Kinemon has devil fruit powers?" he asked.

"Moron" Sanji muttered, throwing a rubber ring over board so Zoro could attach it to his friend and they could pull him back up. Brook collapsed on the deck of the Sunny commenting on how the water was good for his bones. The others left him to it.

Robin sat with Franky and their guests as they watched their friends dive willingly into the ocean. "Are you not going to join them?" Robin asked the cyborg.

Franky shook his head then looked over at the hole on the deck, "I have work to do".

…

Law looked up at the metal object protruding from the ceiling a mere inch away from his head. He had not seen that one coming.

He let out the breath he had been holding and slowly and gently moved away from the weight and remained grateful that it didn't cave in on him. He could not help but wonder if that was intentional or not.

"What a mess!" the voice of the cyborg could be heard from the other side of the hole. Law didn't know why he had the sudden need to hide, but he found himself tucked in the shadows behind some boxes. When he got the chance he would sneak out.

…

Mononsuke watched as Zoro supported Nami in the water until her body relaxed enough to support herself. They then had to focus on teaching Luffy and Chopper how to keep afloat. It had been a long time since Luffy had swam in the sea and Chopper had never been swimming before. Mononsuke couldn't help but feel a little envious. He wondered if Law would be willing to swap him into one of the straw hats who didn't have devil fruit powers, even if just for a short time, so he could see how it felt to swim.

"Woohoo! I am doing it, look, look!" Luffy shouted out to his friends, happy to be swimming once more.

"I thought it would be easier" Chopper stated, sinking slightly and accidentally swallowing some water. Zoro pulled him up from the scruff of his neck. "Thank you" Chopper murmured as bubbles came out of his mouth.

Having helped their friends get the hang of things Nami started to feel better in Zoro's body and could feel the muscles become less tense as the water washed over her. "You were right, this does feel good" she praised the man's advice. Zoro looked at her and nodded. He may not be as smart as she was, but he had his moments and he knew what helped his body to relax better than anyone else.

"I have an idea" Luffy announced "let's have a race!" Chopper did not look keen, he had only just gotten the hang of it, a race wasn't going to be in his favour.

Zoro smirked and said "You're on"

"Hey!" Nami protested, "Not in my body you don't!"

"Then you will just have to keep up" Zoro replied with a mischievous grin, resulting in Nami's expression to become thunderous. Fine, if you want to play it that way we will! She thought to herself.

Nami scanned their environment and spotted a rock like island several metres ahead of them. "See that" she pointed and they all nodded, "the first one to reach that rock is the winner."

"Um guys, can I skip out on this one?" Chopper got the feeling that he was not being listened to.

"Yo Chopper, have faith in my body, I am a pretty good swimmer" Sanji called out, reassuring the little guy, "besides, I don't like the thought of losing to that moss head". Chopper looked up at his own form looking back down on him and felt that if he tried to board the ship he would be thrown back in.

"USOPP!" Nami shouted up and caught the figure of their captain looking down at them. "You be referee" she called out, the man nodded.

"Go Nami-swan, show them what you are made of!" Sanji called out batting for his favourite female and secretly urging Chopper to stay in the lead so he could appear to be a knight for her when her body weakened.

Usopp gathered from his friend's expression that he had momentarily forgotten that Nami was now a man and so the whole damsel in distress thing wouldn't work. The image of Sanji carrying Zoro in a bridal way was actually quite disturbing. He shook his head and turned to look at his friends, "Okay, ready…steady…go!" he called.

They all pushed off from the ship and started to swim. Chopper was surprised to find that when giving his all Sanji's legs took control and the small kicking action provided him with significant power as he sped ahead in front of his friends. Nami and Zoro moved with smooth actions and glided through the waves, almost neck and neck.

Luffy was slightly peeved off that his friends turned out to be better swimmers than him and found the cyborg's metal body heavy in the ocean. Having an idea he paused to doggy paddle and pointed his hands in a triangle like position.

"What is that idiot doing?" Sanji asked, Usopp followed his friends gaze and a bead of sweat poured from his head.

"Um Franky…did you teach Luffy Coup de Burst?" Usopp called out to their shipwright, who came to the edge and followed the gaze of his friends.

"No" he said in response.

They watched in horror together as Luffy shouted, "FART ATTACK!"

Franky was not amused.

A blast of air came out of Franky's rear end and sent Luffy flying into the air and landing on the rock with a loud bang - a small dust cloud forming where he had been.

"Hey that's cheating!" Nami protested as she paused to watch their captain take flight. A mass of orange over took her and she suddenly realised she was falling into last place. She dove into the water and swam with all her might.

"Help me! I can't stop!" Chopper screamed as he saw rock appearing before him and was unable to stop Sanji's legs from moving. He went head first into a metal hand and started to sink into the water. Luffy picked his friend up and sat him on the rock next to him.

"Thank you" Chopper whispered, rubbing his head a little then looking up and scanning their surroundings.

"Come on Zoro, Nami!" Luffy called out, jumping up and down as his friends came up behind.

The shouts of their captain made Nami bite hard on her lip as she sucked in more air. She used her sudden rage of anger to help her push further.

Zoro sensed Nami coming up beside him and fought to push himself harder, pleasantly surprised at how Nami's body reacted with ease. She may not be as physically strong as him but he had to acknowledge she was physically fit.

"Come on Nami!" Sanji shouted from the ship.

"Go Zoro! Go Nami!" Chopper and Luffy called out, not wanting to play favourites at that point in time.

Usopp noticed something in the water and nudged Franky. He pointed to the figure of a huge shadow with a shaking hand. "D…d…do you see that?!" he shrieked.

Franky followed where Usopp pointed, as did Sanji.

"Damn that is huge!" Franky gripped onto the railing.

Sanji spun around and immediately called out to the others, "Luffy there is something in the water!"

"Eh?" their captain struggled to hear them.

The three men started waving their hands and pointing to the water below them.

Luffy waved back and wondered what it was they were shouting.

"Um Luffy…" the wavering voice of the doctor spoke beside him, "s..s..sea monster!" he shouted in fear.

…

Zoro made it to the shore and pulled himself up, already feeling slightly fatigued at the effort he had to put in. He breathed deeply and tried to steady his beating heart. He knew Nami had been right by him and turned to see her approach. She stopped at the edge of the rock, breathing hard and looking irritated. Zoro grinned, he reached out a hand to help her up and she took it reluctantly. He pulled her up but soon struggled to do so.

"Geez" he muttered, now using two hands instead of one, "help me out here!"

"It isn't my fault you are heavy!" Nami snapped. Zoro held back his desire to say that it was more plausible her body was weak.

He tugged at her hand and fell backwards. Nami fell on top of him. He was surprised to feel like he was being crushed and tried to force her off him. Nami managed to get to her knees and moved away slightly, aware of how weird it was to be so close to her own body. She looked down at Zoro whose gaze went past her and to something behind her. She froze and did not dare to turn around. Zoro gritted his teeth and took immediate action, he reached forward and grabbed Nami by the arms, forcing her to fall sideways.

Nami looked up at her own figure kneeling over her in a protective stance. Zoro looked at her, "You alright?" he asked, she nodded slowly, "good" he said. His expression then changed completely as something latched onto him and pulled him back into the sea.

"ZORO!" Nami called out, jumping to her feet and running close to the edge to see if she could see him.

"Nami!" Luffy called as he and Chopper ran to their aid. He looked around, "Where is Zoro?"

Nami pointed into the water. Luffy immediately understood.

"Gum Gum…" Luffy suddenly stopped, forgetting for a second that he could not use his own attacks and suddenly finding himself struggling to figure out what to do next.

Another tentacle swiped at the surface in their direction. Nami shrieked.

The blond figure of the cook ran past them and sent a flying kick towards the tentacle forcing it to retreat. Luckily for them Chopper was used to close combat fighting.

"What do we do now?" Chopper asked, aware that they were limited in their current forms and lacked battle experience in them.

The three backed themselves up to cover all angles.

"I could shoot it" Luffy announced, but I don't have a good aim like Usopp or Franky…I will have to wait until it rises again.

"I could dive in and attack it using the power of Sanji's legs…" Chopper suggested.

"No" Nami announced. "You are not a strong swimmer Chopper, one mistake and you are screwed down there"

Nami waved at her friends on the Sunny and caught Usopp's attention. She gave him a hand signal and he nodded in response.

"What does that mean?" Luffy asked curiously, pulling Nami and Chopper back instinctively as another tentacle came to the surface to find them.

The sound of a cannon gave fire and something clattered behind them. Nami turned and ran to the net that held three colourful metallic blades. She knew Zoro wouldn't be too happy with the fact she just got Usopp to shoot them out of a cannon, but she also knew that without these he was screwed and as good a swimmer as she was her body wouldn't last long under the water.

"What are you doing Nami?" Chopper asked in a panicked voice as she ran to the edge of the rock.

"Distract it for me" she ordered, looking at Luffy who nodded in response and said "Yosh".

Nami tied the swords to her waist and dove into the ocean.

…

A/N: Well just a little bit of action to spice things up…I wonder how they will suffice *smiles mischievously*

Now I am going to go dope myself up and try to sleep! Please let me know what you think! Thanks again for reading and keeping me motivated!

Just to warn you…I go back to work on Monday so my posts may not be as frequent, which isn't necessarily a bad thing as it keeps up suspense and enables people to have time to catch up, but as I can be unpredictable with several posts in space of days to nothing for weeks I thought I should warn you!

I promise I will finish it though! So keep your eyes peeled.
