So I posted a "Luffy get's sick" story just a few hours ago, that had been this version before I changed it a bit. Personally I like this one more, but that's just me. I tried very hard to show Chopper's feelings about what's happening in the story and how he's dealing with the situation. Enjoy~

Edit: just remembered Luffy had gotten poisoned by that fish in the Whole Cake Island arc, but this wasn't inspired by that episode/chapter. I don't own One Piece.

Part 1

Luffy was enjoying himself on the winter island the crew was docked at in the middle of the New World. He wasn't very cold, but Nami and Chopper forced him to at least put on a jacket, which he promptly destroyed on accident almost immediately. Zoro was the one forced to chaperone the captain while the other Straw Hats picked up their supplies, or in the ladies' case, clothes.

After a couple hours of Luffy having fun and Zoro being bored and irritated that Luffy kept randomly throwing snowballs at him, no matter how many times Zoro threatened to injure him, Luffy predictably got hungry. They were a ways away from the ship, out in the middle of nowhere, so Luffy said he couldn't wait and went foraging through the bushes and trees, coming across several colorful mushrooms. Zoro followed behind the idiot boy and saw him stuff the unknown mushrooms in his mouth.

"You did not just eat a random mushroom," Zoro said irritably, already knowing the answer of course. Luffy swallowed and smiled, telling him it tasted great, followed by an angry tongue lashing by the swordsman, who insisted they get back to the ship. Luffy was still very hungry and willing to go back to the ship immediately, so off they went.

The two were lucky they could still follow their footprints easily since it had not been snowing for a few hours. When they finally got back to the Sunny, the log pose had set fairly quickly so they left the island and followed the direction of one of the log pose needles. Luffy would miss the snow. Who knew when the next time they came to a winter island would be?

Luffy was happy. It had been a great day even though Zoro didn't really pay attention to him the whole time. He didn't see why he always needed to be baby sat. It's not like the mushroom had done anything bad. That happened almost four hours ago and he was fine. Zoro had started to worry about the mushroom for some reason. Something was wrong. Maybe it was his weird bond with Luffy that he could tell something was off with his captain before he did himself. He felt irritation that he hadn't noticed Luffy being an idiot and eating something that he didn't even know was edible. Luffy's motto was "everything is edible until discovered otherwise". Zoro felt like telling Chopper, but he knew the young reindeer would freak. Luffy didn't like his crew worrying about him.

Sanji had wanted to make fish that night for dinner, so Usopp, Chopper and Luffy were fishing, not catching much. Luffy was laughing at Usopp's jokes, even though they weren't very funny, before he suddenly felt made a small moan of discomfort before he blacked out and fell off the railing into the sea. It was a loud splash and then it became eerily quiet.

Both Usopp and Chopper sat there for a few seconds before they started screaming that Luffy had fallen into the water, as Zoro was already running to the edge of the ship.

This time he reached Luffy fairly quickly since the waves were calm and the water was beautifully clearer than usual, but something was weird this time. Luffy looked like he was thrashing in the water, which was new. Usually his whole body locks up and he can't move when he's in the water. He grabbed the thrashing and sinking Luffy and made towards the surface as fast as he could. Luffy gasped for air when they reached the surface, but he was shaking like he was having a seizure, making it harder for Zoro to swim back to the boat and rope ladder that was thrown overboard against the side of the ship. Zoro hated that he was usually right when it came to his captains body and mind. Robin bloomed a ladder of arms and pulled the straw hat captain up onto the deck after running to the side when he heard two splashes and a panicking reindeer and sniper. Luffy was flopping around in her arms' grasps, making it difficult to pull him up without dropping him back into the ocean.

Robin became even more concerned as Luffy continued to seize and flop around a bit after he had been set on the deck, his eyes rolled back in his head. Usopp and Chopper ran over to him, Chopper immediately going into doctor mode. Zoro ran over after climbing over the railing and onto the deck, immediately bombarded by Chopper with questions. Chopper was taking Luffy's pulse as he almost interrogated the swordsman.

As Zoro informed Chopper of Luffy eating an unknown mushroom, angry that he had let it happen in the first place, Luffy stopped shaking. His skin was extremely pale, almost translucent and his veins began to be seen. It was eerily fast, his deteriorating body. Chopper had never seen a patient get so bad so fast. Luffy's condition was looking worse instantaneously. He had been fine up until a few moments ago, and now he looked sicker than he anyone he'd ever treated. Luffy then groaned in pain as he opened his eyes, which were bloodshot and hazy.

"How do you feel, Luffy?" Chopper asked quickly as Robin hurriedly went into the infirmary to get the book Chopper had asked her to bring out.

"Hurts and di- dizzy," he mumbled out. By now, the other crew members had come over, and out of the others, Brook was sure of what had happened to Luffy. He was poisoned. He could just tell. Nami was shaking in fear as she saw Luffy in such a terrible state. He looked… wrong. Weak and sick, something Luffy had never and should never look like. Weak and confused and sick. Very sick.

Robin ran out of the infirmary with the book and quickly handed it to Chopper. It was an encyclopedia of fungus and mushrooms.

"Zoro, which mushroom was it that Luffy ate?" he asked quickly as Luffy began to struggle with his breathing. He gave Zoro the book as he quickly flipped through the pages. There sure were a lot of different mushrooms. He began to worry as he got closer to the end of the book and hadn't seen the specific mushrooms in any of the non-toxic sections. Finally he found what looked like the one Luffy ate in the… very toxic section. Shit.

"Uh… This one! The red and white one but instead of circles the markings were more squarish. Chopper gasped and recognized the mushroom. It was in the same family as the Amiudake, the mushroom he had accidentally fed to his father and killed him. He had done extensive research with the help of Doctrine on how to treat what mushrooms. This was one that he had not learned to treat. Because it couldn't be treated and certainly not cured, not without a miracle, the kind no human could bestow. If there was a god somewhere, it'd be up to them to save Luffy.

"Oh no," the reindeer doctor whispered. He couldn't tell the crew there was a one percent (more like half a percent) chance he could live. He knew it was wrong to give false hope, that had been beaten into his mind by both doctors he studied under. But he couldn't tell his family that Luffy was almost certainly going to die.

"What? What is it?" Nami asked nervously.

"It's a poisonous mushroom. It's almost completely fatal. A five percent chance of surviving," he lied. "Luffy, can you hear me?" he asked calmly, trying his best not to scare the sick boy and burst into tears. Luffy didn't seem to be coherent, and started mumbling about Ace and someone named Sabo. "Luffy?" Chopper repeated louder, this time getting Luffy's attention.

"Huh? Where am I?" Luffy asked in a slur. His fingers were twitching and he had some drool pooling from the corner of his mouth. He coughed and wheezed but then relaxed, looking at the people around him, confusion apparent on his sickly face.

"On the Sunny, Luffy," Sanji said, starting to sound concerned. He couldn't remember where he was? He was directly under the sails and facing towards Sunny's head.

"Whaza Sunny?" he asked, still clearly confused. "Who're you?" Luffy asked Sanji, who was shocked at the question. Luffy sluggishly closed his eyes like he was going to fall asleep, only to be rocked awake gently by Chopper. He could sleep in a moment, in a more comfortable place. Everyone looked shocked at Sanji and then stared fearfully to Chopper.

Chopper gulped and said, "Luffy, I'm gonna move you to somewhere more comfortable. Then I can help you fall asleep and relax."

"O- ok," Luffy mumbled before going straight back to talking about his dead brother and whoever Sabo was. Chopper turned into heavy point and carried Luffy easily to the infirmary and laid him down on the hospital bed. With the help of Zoro and a still shocked Sanji, they dried him off, stripped him and then put him in a warm fluffy robe. They'd get him some bottoms in a while.

He gently spoke to Luffy and informed him that he'd need to take some pills if he didn't want an injection. It took a few minutes to get Luffy's attention and repeat what he told the sick captain a bit louder. Luffy took the pills, spilling water all over his neck and face. Chopper got a towel and wiped the water off as Luffy fell into a deep sleep and then put an oxygen mask over his mouth and nose. He would not underestimate this poison, and he needed to feel he had done all he could, even if Luffy's passing was set in stone.

Chopper didn't feel comfortable leaving Luffy by himself when he was so ill, so he called for the rest of the crew to come in and speak quietly.

"How is he? What's gonna happen to him? Is he ok?" Usopp asked, obviously panicking. Luffy looked worse than any injury ha'd ever gotten. He even looked worse than when he was paralyzed and bleeding after he beat Lucci.

"I said before… he has a... very low chance of surviving. The mushroom was in the same family as Amiudake, which kills the victim within the hour. Thankfully, he has a longer time to try and survive, around three or four days, but it's also unlucky. When he's not asleep, he's going to be disoriented and hallucinating while in pain, though I don't know for sure since he's not a normal human. He may sustain some memory loss, but if he lives… it shouldn't be permanent," Chopper said sadly, but still maintaining his professional voice. "Nothing I say might happen. I've never treated someone with a Devil Fruit other than stitching Luffy up and giving him some pain medicine and left the rest up to him…"

"What other effects with there be?" Zoro questioned. He knew it had to be worse than Chopper was saying based on the way his voice shook. But he couldn't see through Chopper's expert lie. He didn't know Luffy was in a worse situation than he could have ever been in.

"Well, the poison from this mushroom targets the blood system and brain. If his immune system fails fighting off the poison, he won't recover from the poison at all… and will die. The hallucinations will become stronger and more often as time goes on. He'll most likely have more seizures… It won't be a good experience for Luffy." He took a deep shuddering breath and continued, "I- I don't want more than two people being in there. He didn't recognize Sanji. He may panic if he's stuck in a room with a large group of people he sees as strangers. Sanji, you should only go in when you bring him meals," Chopper apologized when Sanji looked upset, telling him bringing food may help Luffy remember who the cook was. "There's also a small chance he won't be able to speak anymore…"

The crew couldn't really comprehend this. Luffy? Not talk? He wouldn't be Luffy if he couldn't talk and be annoying. But it felt better to be upset over that instead of the fact Luffy could die easily.

Robin spoke next. "Is it safe for him to be asleep?" She looked quite concerned, no longer calm, even less calm than Chopper was. Her lips were trembling. She looked more scared than she had when they had been separated by Kuma. And she was terrified then. But seeing Luffy like this is more horrible than not knowing what happened to her crew. At least then, she could hope and believe they were still alive and okay. Luffy barely looked alive right now.

"It's fine. I can give him medication to help him with the pain. But this is Luffy, and I'll say once again, he's made of rubber so I'm not positive things will go how its supposed to. And there is no real treatment for the poison, but the brain failing is the main problem. If any of his other organs were to fail, it would be possible to save them… but not the brain… A lot of his chance of surviving is based on his will to live but- but that might not be enough." He couldn't tell them they should say their goodbyes. He couldn't.

Chopper's diagnosis still hadn't hit the rest of the crew. Luffy, dying? How stupid. They were convinced Luffy was basically immortal and invincible. He'd be fine and make it through this. He'd then joke about it inappropriately, like when he was frozen by Aokiji.

Franky then asked something no one had thought of. "Wait, he's supposed to be immune to poison, so why is this affecting him?"

"We don't know how he became immune to poison, so there's no way to know why or how that works. It could be for only some types of poison, and poisonous mushrooms can be very bad. I'm going to stay in here for now. Does anyone want to stay in here with me?" Chopper questioned. Zoro was first to say he'd stay, and no one argued. Sanji informed Chopper sadly that he was going to start dinner and asked what he should make for Luffy. He couldn't even look at him lying on that bed, having already forgotten who Sanji was.

"When he wakes up, make him broth and maybe some apple sauce later. Please bring some water in a bottle when you leave." Chopper sighed, "I want him to be able to eat and drink, not need liquid nutrients and water hooked up to keep him fed and hydrated."

"I'm sure he's gonna love that. Either eating non-fulfilling food or not eating at all," Usopp said somewhat dryly. The severity of the situation still hadn't clicked with him. Nami glared at him.

"This is no time for jokes!" she whispered harshly at him. Usopp blushed and apologized quietly, though he didn't mean his words to sound like a joke. There was no point in arguing at the moment. Not while he could hear Luffy's somewhat heavy breathing.

"He may not remember what his favorite type of food is if he's going to have memory loss. If he forgot who Sanji was, it won't be surprising for him to forget something like meat," Robin mentioned.

The others left besides Zoro and Chopper. Zoro sat against the wall across from the bed Luffy was sleeping on. Zoro watched as Chopper hooked Luffy up to a machine to show his heart rate and tried making Luffy as comfortable as possible. He adjusted the bed and fluffed the pillows and rearranged Luffy's limbs so he could be in the most relaxed position. Zoro was asked to get some underwear for Luffy and then they changed him, adding a couple layers of blankets over his still form to keep him warm.

It was a little over an hour that Sanji brought Zoro and Chopper dinner, which was a simple sandwich for everyone with their favorite food on it. Luffy woke up before he should have thanks to the smell of the food in the room. Neither Chopper nor Zoro noticed him wake up until he started talking to Sabo about a tiger. Chopper became worried as Luffy moaned from being uncomfortable, so he adjusted the bed again so he was in a more sitting position.

Zoro put his food down and kneeled next to the bed as Chopped took Luffy's temperature. He said, "102.4", aloud and sighed. The fever would probably stay present. Chopper took off a layer of blankets and put a wet washcloth over his head while Luffy continued to talk to no one.

"Luffy, who's Sabo?" Zoro asked clearly and a bit loud so Luffy could hear him. It seemed that was what made him realize there were other people in the room.

"Nii-chan," he slurred. Zoro questioned that he had more than one brother. He had never told any of them about another brother. "He's dead," Luffy said surprisingly clearly and looked at his hand, hallucinating that it was covered with bubbles. "Bubbles?" he asked curiously, diverting Zoro's question about Luffy's second brother. Now was not the time. Luffy slowly wiped the bubbles he saw on the blanket, confusing Chopper and Zoro.

"I should put him back to sleep," Chopper said, reaching for the pills before Luffy mumbled he was hungry. Zoro immediately left the room to get Sanji to make him some food while Chopper was conflicted about letting him stay awake for an extended period of time. It was clear he was starting to hallucinate more than before. He looked around the room like he'd never been there before. Chopper finally decided Luffy needed some food more than sleep at the moment.

Only a couple minutes later Sanji walked in and brought the bowl of broth near Luffy and sat down next to him to spoon feed him, for once not feeling awkward about helping one of the boys while they were sick. Luffy was very sick so Sanji wasn't going to be his usual self concerning the same sex.

Luffy had gotten a lot of the broth down so there was only a bit left. He reached up to try and take the bowl, spilling the hot liquid on his neck. He felt too weak to scream at the moment so he just moaned in pain, scrunched his eyes, and touched the burning liquid on his neck.

"Shit," Sanji said, trying to take a towel and wipe him off, but Luffy turned his head away from Sanji and tried to scootch away from him a bit, but mostly barely flopped, his head lolling around on its side. He seemed to go in and out of being able to speak. Right now, he couldn't speak.

Chopper looked sadly at the scene before taking the towel himself and wiped it off before going across the room to get some burn cream he had made. The burn wasn't too bad, but Chopper didn't know if Luffy's pain tolerance had been affected. Usually he could handle things like being stabbed.

Sanji knew he fucked up here, even though it was mostly Luffy's fault. He picked up the bowl and left, depressed and furious at the same time. He ran into Zoro outside of the room and took his anger out on him.

"This is all your fault!" Sanji shouted. "You were supposed to be watching him and this happens!"

Zoro grew furious. He knew it wasn't all his fault, but it was his responsibility to keep Luffy out of trouble while he played in the snow, and looking away for just a moment had doomed the boy. Zoro actually punched Sanji in the face and told him to "shut the fuck up" and then stormed back into the infirmary, almost slamming the door behind him before he looked at Luffy and closed it quietly.

Chopper had given Luffy his sedatives and medication to help with his pain. The sick teen was now sleeping again. Zoro noticed the bright red area on his neck. "Chopper what happened to him?" he asked, concerned.

"He spilled some soup on himself. I think he's afraid of Sanji now," Chopper said sadly. Zoro now knew why Sanji had been so angry, though he still was irritated he took out his anger on the first person he saw, which had been him. At least Zoro got a good stress relieving punch. He knew Sanji would be pissd for a while and Zoro was only not kicked at because of their mutual concern for the straw hat captain.

It was another three hours that Chopper and Zoro stayed in the room with Luffy. Chopper was sure that Luffy would stay asleep longer this time since he had given him a stronger sedative. This one would last for five hours. Luffy moaned in his sleep a little bit. The poison stung all over his body. The sedatives were good for him. Zoro eventually left by Chopper's order to go take a nap or something, who was replaced by Robin. She sat next to him as Chopper took a short and much needed nap and read a book.

Luffy woke again a couple hours later, confused that Zoro and Chopper weren't there. Well, he thought he'd woken up. He was even more confused that he was surrounded by stone walls in the dark, chained to a slab of stone. He was writhing in pain and began to cough up blood and scream, feeling his body being ripped apart from the inside. He was left alone for hours and hours, coughing up blood and screaming.

He was shaken awake gently, screaming, by Robin. He looked around and saw he was no longer in a dark hole and was on a mattress, not a stone table.

"Luffy, it was all a nightmare. You're safe," she said. Though she knew he wasn't safe in his own body, and didn't look safe at all. He was still pale with his blue and red veins clearly visible through the skin. He stopped sobbing after a few minutes, and then became silent. "Do you want to talk about it?" Robin asked, though she thought he wouldn't be able to string coherent words together to make sentences.

"Impel Down… Magellan… poison… ten years… Iva-chan," he jumbled the words together. He looked at his wrists, which were free and not in chains. It was around midnight and mostly dark in the room. Chopper had went to use the bathroom, so he wasn't in the dark room, except for a single lamp next to where Robin was sitting. She could hear a bunch of footsteps coming from a room near the infirmary, so she bloomed a mouth and ear in the men's quarters, telling them Luffy had a nightmare and was fine. The footsteps stopped.

"You don't need to talk about it anymore, Luffy," she said kindly, though she was painfully curious about his nightmare. He suddenly began to cough violently. Between coughs, he moaned out "Iva-chan save me" over and over. To say Robin was confused was an understatement. Who was Iva-chan? How could this person help Luffy?

She was pulled out of her musings when Chopper came running in. "Is he ok?!" Luffy had stopped coughing and was now moaning and holding his throat, hurting from the screaming and burn. He had pulled the oxygen mask off after the started coughing, but Chopper put it back over his face.

"He had a nightmare," she said simply, planning to go into more after Luffy fell asleep. "Can he get anymore sedatives yet?"

"No, he has to wait another hour. Even if he's going through it faster than normal, I don't want to risk him overdosing." Luffy didn't react to their conversation about him as he looked around, seeing star-like glowing dots flowing through the air in the room. Chopper looked from Robin to Luffy as he tried reaching the bright dots swirling in the air above him. Chopper gently took his outstretched hand and pulled it down back to the bed, patting it soothingly. Luffy was still out of it as he continued to watch things swirl around in the air.

"I'll try reading to him," Robin said and picked up her book, one she'd read many times and that Luffy had once shown interest in it, and held his hand gently. She began to read about the Rainbow Mist. Luffy listened to the story silently for the remaining hour. She couldn't really tell if he was processing her words, but he stayed relaxed and quiet, so that was good. Chopper fell asleep to the story. He was so tired. He'd been awake for a very long time and the stress wasn't helping.

Robin felt bad when she had to wake him an hour after Luffy had woken up. Luffy turned his head to Robin as if confused she had stopped reading. He started to cough again, horrible throaty coughs that sounded painful and the seizures started again, but this time he was awake and looked absolutely miserable but still had hazy unfocused eyes. He knew he didn't like what he was feeling, but he didn't really know what it was or what could make it better, so he laid there limply and tried not to fight the motions.

Chopper took Luffy's hand again and apologized from the bottom of his heart that there was no treatment, but told Luffy he knew he could make it through this, though he couldn't. He needed to give Luffy hope. Luffy continued to seize as Chopper spoke. He had to wait for the seizures to stop to give Luffy his sedative.

Finally, Luffy's body became still and Chopper immediately made him take his medicine just in case the seizures came back and then put the oxygen mask back on. Luffy fell back asleep, but even in his sleep he looked miserable.

"Chopper, please tell me the truth about his chances. I know you have been hiding the truth."

Chopper sighed, but needed to come clean to someone, and Robin was a good choice in his mind. "He has half a percent chance to live. And even if he lives, he may come out permanently damaged. I'm trying to prepare myself for his death, but it just isn't clicking. Luffy can't die. But I know he will and I just can't feel sad about it yet. Don't tell anyone else yet."

Robin stayed quiet while he spoke, shill holding Luffy's pale and clammy hand as he slept deeply. She bit her lip to stop the tears. She wasn't usually an emotional person, but Luffy was important to her. He saved her time and time again in every sense. It was also hard to comprehend him dying in such a… pathetic way.

She hugged Chopper as they watched him sleep and breathe heavily. He still had a miserable expression on his face.

So the first day passed and Luffy's condition had gotten worse.

Review please!
