"WAHHHHH~!" Chopper screamed. His wails echoed for miles out into the open sea as he ran circles around the deck of the Thousand Sunny. It wasn't unusual for the young reindeer-boy to overreact to things so it was often hard for the rest of the crew to take his cries seriously until they knew exactly what set him off. Nami sighed as she stood up out of her sun-chair and walked towards the terrified young boy.

"What is it, Chopper?" she asked, grabbing hold of his head as he darted by, stopping him in place. Tears were firing out of his tear ducts.

"It's Luffy!" he shouted, trying to make sure that everyone heard him. "Something's gone terribly wrong I've never seen anything like it!"

"Calm down!" Usopp piped in. "We can't help you if you don't tell us what's up." Chopper snorted up an elongated snot drip that had begun to fall from his little blue nose.

"Go look for yourselves!" he cried and pointed towards the mens' bedroom. Nami and Usopp looked at each other and shrugged. They followed Chopper into the bedroom to see a truly surprising sight. Luffy sat kneeled on the wooden floor and looked up with confusion. It was clear that he had no idea what Chopper was freaking out about either.

"Seriously?" he asked. "Chopper, I feel fine." Except, there was one major issue with the scenario that the young pirates were now seeing: Their fearless leader, the infamous captain of the Straw Hat pirates, Monkey D. Luffy, was now unquestionably a woman. He/she now had a distinctly large bust peaking out behind his/her open red jacket. His/her body's curves and face had become much more feminine as well. It was truly an appalling sight to the young crew. Nami and Usopp shrieked in unison.

"Yohoho... What seems to be the problem?" Brook asked as he the scene with Robin following closely behind. He sees the new female Luffy and pauses in mid-breath before falling on the floor into an outrages fit of laughter. "Yohoho! You never know what kind of perils you'll find on these waters! Yoho!" he shrieked from the floor, not likely to pull himself back up anytime soon.

"L-Luffy...?" Nami stammered. Brook continued laughing in the background. "What the hell happened to you...!?" she was clearly not comfortable with this arrangement. Luffy looked down to see her new cleavage. This was something new to her as well, but she was oddly unfazed by it.

"I don't know." she said. "Chopper and I were just checking out that weird fruit we found on the last island and I decided to see if it tasted good."

"A Devil Fruit!?" Usopp panicked.

"Not likely." Robin chimed in. "I think I've read about these things before. I was planning on studying the one that we picked up, but now..." The archaeologist was always so calm in these situations.

"Then what is it?" Usopp asked.

"Since it's just a legend it currently remains unnamed, but there have existed faint records of a strange fruit, a type even rarer than the Devil Fruit, that can manipulate a person's gender."

"Eh...?" Luffy cooed. "You mean like Iva from Impel Down!?"

"What're we gonna do about this!?" Nami cried. "Is it temporary? I don't think I can spend the rest of this voyage with my Captain looking like... that!"

"That's the problem with there being such little information out there." said Robin. "Our best bet is probably to turn back to the island and speak to the man who sold it to us."

"We can't just turn around on the Grand Line! The island's not even in sight anymore!"

"Well, you're the navigator." Robin smiled. "I'm sure you could figure something out!"

"Well... There's no helping it, is there?" Nami said with a big sigh. Chopper scooted over to the new Luffy and started poking her arm, almost like he was afraid of catching the disease himself.

"Does it feel weird?" he asked.

"Not really." Luffy shrugged. "My chest feels kinda heavy, though..." Nami holds her arm out to help the feminine Luffy up.

"C'mon, let's see what we're dealing with here." she said. Luffy grabbed Nami's hand and stood up with her help. It was now even more clear that Luffy was just as curvy and well-endowed as either of the other ladies on board. Nami blushed.

"Wow. Aside from the boys' clothes you make a shockingly cute girl!" she exclaimed.

"What do you mean?" asked Luffy. Nami waved her hand back and forth in dismissal.

"Nevermind... Let's just try to figure this situation out." she said. Nami led the group that was huddled together in the bedroom back out onto the deck. "Franky!" she called out. "We're changing course!"

"Huh...? What for?" the hulking cyborg asked. He turned his head from where he was standing at the front of the ship. The new Luffy caught his eye and his heart sank and he immediately broke into a fit. "What the hell is that!?" he shouted, grabbing onto the rail and almost shattering it underneath his bulking mechanized hands. "Something's clearly not right here! This is a joke, right?"

Zoro was sleeping on the edge of the Thousand Sunny's lawn when Franky's commotion woke him up. The group's heads all turned towards him in unison. Zoro noticed Luffy. He held his gaze on her for a few seconds to let it sink in. Then he fell right back asleep. The rest of the crew's jaws dropped in disbelief that he could have such an underreaction.

"We're gonna have to explain this to everyone, huh?" Nami said with another big sigh. "I guess now everyone's at least seen Luffy except..."

At that moment, Sanji burst out of the kitchen, pirouetting with a couple of freshly made dishes. His one visible eye sparkled with hearts as was often the case.

"Nami-swan~! Robin dear~!" he swooned. "Dessert's ready!" He continued to spin around in his own little world with little awareness of his surroundings. He then sharply stopped in place. "Huh...? Why does it feel like something's wrong?"
