Hey guys! Here's the part everyone's been looking forward to- Zoro! Now, I kept saying this was a complicated fight scene, but it turned complicated for a different reason than I anticipated, while I was writing. So Vegapunk finally appears, and I'm still editing Dr. VegaPunk's conversation with Conan, which is the next chapter, but there are several things I need to say. First of all, everything I have down about VegaPunk is pure theory, he hasn't actually shown up in the anime or manga, so I guessed completely on his appearance and personality. I did what suited my story best, and if you don't like it, feel free to complain. So, without further ado, here's the next chapter of my crossover! Please read, enjoy, and review!

"Er…I came here with a pirate crew who knows the owner of this island. Then they ditched me out here, and I ran into those things, and you guys saved me. What were those things anyways?" Conan pointed to the strange animals.

"Those things are humandrill, their so intelligent that they can imitate humans without a problem." Perona whimpered. "So intelligent, that they can wield a weapon."

'Yet another weird creature to add to the ones I've already seen.' The detective inwardly sighed. "So, what are you guys doing out here?"

"This idiot's trying to prove himself to that Mihawk-bastard so that he can learn swordsmanship from him!" The gothic girl exclaimed.

"Mihawk?" Conan repeated.

"Eh. Dracule Mihawk, he's the master of this island, that your friends claim to know." Zoro explained. "He's the world's greatest swordsman, and I intend to surpass him one day."

"Well…those pirates aren't really my friends, they brought me here out of pity." The detective admitted sheepishly. "So…what are you guys doing out here?"

"Mihawk had said that if I make it through the forest of this island, then I become his apprentice." Zoro explained.

"Uh…80% of this island is forest. Are you sure he just didn't mean for you to reach a certain point to show that you're serious?" The detective pointed out.

"He did! This idiot just wouldn't listen!" Perona complained. "Anyways, we're supposed to go to the cathedral of this island, which apparently is about two miles that way." She pointed to the woods behind Conan. "It's the prime of the humandrills' territory, and apparently they're guarding something big."

"Really?" The young detective wasn't sure if he wanted to be caught up in this. "I'll just get out of your way then."

"Once these things have decided on prey, they won't let you go." Zoro eyed him sadly. "I'm afraid you're stuck with us, at least for now."

"I don't think I'll be any use to you, though." Conan tried to reason.

"Doesn't matter, I already accepted the challenge from Mihawk, and going back for any reason is considered throwing in the towel. You're with us until this whole thing is over." Zoro replied and walked ahead of Conan. "Let's go, we're wasting time."

"B-but, it's dark! They outnumber us! Roronora-san!" Conan shouted after him. "Do you even have a destination point?"

"Ah. As she said, the cathedral; we're supposed to retrieve a rosary from there." The swordsman replied. "Now, you idiots keep up, otherwise the humandrills will get you. They've imitated the army that they had wiped out before Mihawk got here, and the strongest one, even has a replica of Mihawk's sword."

"Why didn't I stay at the castle?" Perona whined.

"Enough wasting time, let's go." Hesitantly, Conan and Perona followed; wandering into the darkness.

3hrs Later

After wandering through the woods mindlessly, Conan concluded that he had officially met person with the worst sense of direction. They had double back around the woods twice, even winding back at the ruins. Conan had thought it was strange that they came from the beach, and had already been past through the area, but it soon became obvious why. Zoro couldn't keep track of where he was going, and Perona was too scared to leave his side; so they had gone in two complete circles with an approximate two mile radius. The detective had no idea where this supposed 'cathedral' was, but he had to find it. He knew Shanks had set them up, so he was certain VegaPunk was in the church. It was poetically ironic, an evolutionist scientist in the church of God.

The detective was relatively atheist with hint of agnostic; he had to keep his indifference to religion for the sake of his analysis. Speaking of analysis, Conan was currently trying to wrap his head around the situation he was in. He went from being lead around by Shanks and his crew, to an accomplice of an invasion. Those monkey-like creatures didn't look particular friendly or weak, and even with his upgraded utility belt, he wasn't sure how much it would defend him. The swordsman didn't seem too bright, the gothic girl seemed useless, and it was obvious that neither of the two of them trusted him. Not that the detective blamed him, his appearance couldn't have been timed worse for the swordsman. Ironically, he found himself to be the group's navigator, making himself useful to the warrior. Speaking of which, he wondered what position the man had in the Strawhat crew- enforcer? Look out? Bodyguard? Deciding to strike up a conversation, he spoke.

"So, Roronora-san…how come you're on this island?" They hadn't spoken a word in the past three hours.

"I was sent here flying by some bastard." He gruffed.

"Ah. You don't say, sorry to hear that." Conan sweatdropped. 'He's a lot less open than the other Strawhats.

"So…are you a bounty hunter, or…?"

"Why is is it your business to know if I'm a bounty hunter or not?" He turned back to the boy with a glare.

"Oh honestly! He's the first-mate of the Strawhat crew!" Perona exclaimed.

'Called it.' Conan thought.

"Quiet woman!" He snapped at her and looked back to Conan. "Why do you want to know?"

"Because…I'm doing a report for school!" The detective couldn't believe he came up with such a lame lie. "You see…I'm supposed to record everyone I might on an independent expedition of self-discovery, including names and occupations of said people!"

"Ah really?" Zoro's eyes widened. "Geez, the things teachers do to their students sometime…sorry I doubted you."

'He actually bought that?' Perona and Conan were hanging their mouths open in shock.

"No way! You're buying this? Are you completely stupid?" The ghost girl exclaimed.

"I'm not being stupid, what other reason would he have to be here? He's just a little kid." Zoro replied. "Keep close, I sense some of them up ahead. Kid, we going the right way?"

"Uh…" Conan looked at his watch, which also functioned as compass. "If the directions Mihawk-san gave you are correct, then the humandrill's territory should only be about 500ft ahead."

"Okay, listen up." The swordsman turned to his weaker companions. "According to that Mihawk, these things a strong as they are smart; they took out the previous humans who lived on this island and took it upon themselves to copy the ranking system in their army."

"Wait, these things are actually imitating humans?" Conan exclaimed. In his world, he had never come across this type of intelligence in animals.

"Ah. Not just that, but they also took the army's weapons and tactics too. The only person to defeat them is Mihawk, and soon to be me as well." Zoro drew one of his swords. "Perona, use your powers to watch over the boy, I don't want either of you getting in my way."

"Why, I never!" She huffed.

"You actually plan to take on a whole army on your own, Roronora-san?" The boy asked.

"Ah. The Strawhats have taken on worse, ask those Enies Lobby bastards." He smirked, not noticing Conan's wide eyes of surprise.

"But still! Do you even have a strategy for fighting these things?" Conan tried to reason with the man.

"Sure, cut them all down, until none of them are left standing." He smirked and drew his other sword. Peron and Conan followed closely behind him.

"Roronora-san! Think about this! You can't just blindly charge into an army, like that!" He argued.

"Maybe, you two can't, but I can." To the detective's astonishment, Zoro drew his last sword into his mouth. Never, in his cases, had he seen this. Even with Makoto's matches, he had never seen it. He gulped, realizing that he hadn't actually seen any of the famous Strawhat pirates fight until now. And if he was strong enough to take on a full army by himself, then just how strong was their captain?

Conan's thoughts were cut-off when Zoro abruptly stopped in front of him, causing the boy to bump into him. "Stay sharp, we're here." The detective blinked and went around to Zoro's left side, only to be kicked aside harshly by the man.

"Hey, what was that-" Conan was cut off by the sight of an axe occupying the space he had been in merely seconds ago. He stood up, and looked ahead and his eyes practically bugged out of his head. In front of him, was a large clearing of grass about a mile long, with trees and shrubs around the sides of it, giving it a natural lawn. But down the grassy lawn, was a large, stone, cathedral that looked to be about thousand years old, it had several stained glass windows, and was about half the size of Buckingham palace with the same medieval architecture. But on the grassy plain and all in front of the cathedral, was the promised army of humandrills, carrying the same kind of armor and weapons he had encountered earlier. Narrowing his eyes, the detective immediately knew, that was where Dr. VegaPunk was; he had to get in there. Looking at the humandrills, things suddenly made sense, no one could find Dr. VegaPunk because they were all vanquished in the search, or people simply wouldn't think to look here. Either way, Shanks and this Mihawk-san set things up to where the scientist would be both safe, as well as prosperous, at least he hoped for the second one.

"Kid, stay back and hide with Perona. Under no circumstances, enter this battle. My captain would never forgive me, if I allowed a kid to get hurt in a fight." Zoro positioned himself, and prepared to attack. "Perona!"

"Hai!" She quickly grabbed the boy, and levitated a safe distance into the air.

"Hey!" Conan struggled to get out of her grip. He looked down at the man in panic. "Roronora-san!"

"Call me Zoro, I don't like how my last name sounds." He snorted. "Just sit tight, this won't take long." As soon as he said that, he charged forward.

"ZORO-SAN!" Conan exclaimed. The detective had never once seen active combat, sneaking out of places, being people's hostage, and outsmarting armies were completely different. He had never once seen this kind of fight before, and he couldn't say he particularly cared for it. It was terrifying!

In a few short blurs, Zoro had successfully taken out the first wave of them. The swordsman's movements were so fast, that Conan honestly couldn't keep up. He briefly wondered if Makoto could keep up with these kind of movements. "He's incredible."

"Duh! He's the first mate of the Strawhat crew, of course he's powerful! This crew's famous for taking out armies, warlords, and forces of nature! They took on Enies Lobby, the World Government, the Tenryuubito, Oars Sr., Gecko Moria, the list goes on! These guys are serious business!" Perona quacked.

"I'm just going to assume those are very nasty people to fight." Conan had no idea who she was talking about at this point, there were too many characters to memorize. But his breath was shaken, when it looked like Zoro took out one of the commanders. "Still though, if the first mate is this strong...just how strong is their captain?"

"Oh! Luffy-san's way stronger than this! He did defeat master Moria on his own, after all." Perona answered.

"So it wasn't a joke when Magallen-san said that Luffy took on Impel Down on his own." Conan muttered, almost wincing at the narrow escape Zoro made from a battling ram.

"Nope. Strawhat Luffy's the most well-known rookie pirate in the world, only second in bounty to Eustis Kid." She informed him.

"You don't say." Conan remembered the bounties of the Supernovas back at Marineford. "So Luffy-san's a scary person, huh?"

"Hm...depends on what you mean by scary." Perona shrugged.

"Uh..." Conan was about to answer, when, "ZORO-SAN!" The swordsman was thrown back by a gorilla of the primate army, and it had a battle axe, bigger than his hand. Jumping out of the girl's arms quickly, Conan readied his taser. "Zoro-san!" He cranked it up to full power, and shot the electricity out. Sentomarou did an awesome job with his gadget upgrades, an entire lighting bolt shot from his watch and hit the gorilla straight on. The detective stopped in his tracks, stunned at what he just witnessed.

Suddenly, the army of humandrills' attention was suddenly on the boy, giving the swordsman a chance to breathe. Very slowly, Conan went to his belt, and got out his soccer ball. If his taser shot lightning, let's see what a projectile would do. About three humandrills came at him, and he took his chance to shoot the balll. Conan knew the ball would hit the gross primates, what he didn't realize was that it would aim for all of the monkeys coming up against him as well. In a matter of ten seconds, twenty human drills lay unconscious, while soccer ball rested at the detective's foot.

"Whoah..." Perona landed beside Conan. "Er- I mean! Hey! You're supposed to stay with me!"

"Sorry-"

"GRAH!" A giant mandrill-humanoid jumped up behind them with a katana, but it was kicked away, the second it appeared. Zoro quickly grabbed the both of them and charged towards the cathedral.

"Zoro-san! What are you planning to do?" Conan demanded.

"Simple. Since you're not as useless as you look, you and this woman are going into that building to get that thing Mihawk wanted." The swordsman dodged giant hands and axes from the primates.

"But what about you?" Conan demanded.

"I'll be fine, just stick together and get out as fast as possible." He replied.

"Oi! I don't want to work with him!" Perona complained.

"Too bad." The marimo grunted.

"But-" Conan never got to finish his sentence, as he and Perona were thrown into the Cathedral, shattering the stained glass in the process.

Landing on the ground, Zoro turned to the rest of the humandrills coming up to him from the forest, determined to protect whatever was in there. "Tch. Damn bastards." Zoro charged forward, ready to get his revenge on these primate-bastards. Damn them from keeping him from his crew.

With Conan

The detective groaned and got up from the floor, he looked up to see the shattered window he fell through. He looked around himself, and found that he was in a chapel or worshiping room of some kind. It was dark, had traditional church aisles, and a traditional catholic alter. Frowning, he called out. "Perona-san?" No answer, Zoro must've unintentionally thrown them into different areas of the church. Shrugging, the detective decided that this oppurtune moment was the best time to find VegaPunk. Perona had the power to control ghosts, she'd be fine. Really, out of all the devil fruits Conan had seen so far, hers was definitely the most useless.

Sighing, he left the alter and walked down one of the various passageways in the building. This was honestly the creepiest gothic church he had ever been in. The church was as black as 'The Exorcist', there were dead roses everywhere, and he was sure the place hadn't been cleaned in ages. Really, all it it needed was Dracula's coffin and Van Helsing would come in and have sex with a random girl. 'God! I miss home!' He hated Van Helsing movies, yet he was referencing one; that just showed how homesick he was. Frowning, Conan tried to think, if he was VegaPunk, where would he hide in this old place. With all the security and isolation this island provided, he couldn't imagine why the scientist would need to hide, but then again...he had just learned that truly anything was possible.

Noticing a library was coming up, Conan decided to try his luck there. Walking into the place, it reminded him a darker version of the Mariejois library. Deciding that it couldn't hurt to find a light-switch, Conan felt around for one, but was shocked to not only find one, but it also worked. The light went on, which meant this place most likely had running water and indoor plumbing. "That means someone actually is using this place." The boy quickly glanced at the bookshelf, and his eyes bugged out of his head! They were all books on the Void Century and other related to topics. One book in particular caught Conan's eye, and quickly took it out of the shelf. He checked the copyright date, and noted that it was last updated this year, meaning that VegaPunk was more than aware of what was going on with the world. The title of the book: The World's rulers and servants, was a collection of documents and records of people who not only ruled over the Void Century, but also had detailed notes regarding it.

Conan took out the pictures he stole from the Tenryuubito's lockbox and compared them with the pictures in the book. His eyes widened, five of the men in the first picture he stole, matched the Gorosei's pictures in this book, and according to this picture and the book, this was 800 years ago, and there were originally twenty men, not five. What happened to the other fifteen? If what Conan was theorizing was true, how was this possible? Did that mean they achieved immortality? How had they succeeded? Frowning, Conan compared the second picture in his hand, which featured the very lovely couple from Kong's office. After turning to the royalty section, Conan smirked in satisfaction. "Bingo." The picture in the book was an exact copy of the picture in his hand, the last king and queen of the Void Century. The detective quickly tore out the pages of the information, and placed the book in his backpack.

"It's not nice to steal, yah know." That was the last thing Conan heard, before a sharp pain struck his head, knocking him out.

With Perona

"Oh...where is that brat? That swordsman's going to kill me for losing him!" The gothic girl whined. "I even got the stupid mark too!" This mark, was nothing more than Mihawk's sword-cross necklace that he was seen wearing. Apparently, it had accidentally fallen off him sometime ago, due to a broken string, and it was picked up by the humandrills, and then VegaPunk. To prove themselves, they had to retrieve a pocket knife! A pocket knife! Perona was so pissed! And now, she was stuck in this creepy place, looking for that brat. Suddenly, the sound of a closing door got her attention. "Oh screw this!" She summoned a persona. "Go find him!" She ordered it!

The ghost sauntered off, looking for the source of positive energy.

With Conan

The boy struggled to open his eyes, and inwardly cursed at the pain in his head. He rubbed it, only to find that it had been bandaged, he looked down to see his belt was on him, but it had been taken off. His backpack lay on a wooden chair beside the bed. He looked around himself, to find that he was in a very simple bedroom. It had a dresser, a lamp, a bathroom, and a bed, but that was about it. Conan carefully got out of bed, and went to open the door, which was unlocked surprisingly. The detective walked into the most advanced technological laboratory he had ever seen, even Agasa didn't have this many computers and electronics. He frowned and looked around for the jerk who captured him.

"Anyone ever tell you, it's rude to steal, Kudo-kun?" Conan jumped at an unfamiliar voice, spinning to his left. There was a large man with a purple mohawk and labcoat sitting at a desk, his back turned to him. He wasn't looking at the detective, but Conan could easily feel the animosity.

"Anyone tell you that desperate times, call for desperate measures." Conan retorted. "Who are you? What is this place?"

"You've been looking for me, for awhile, I'm sure you know who I am." The man turned around, allowing Conan to see him fully. The lab coat covered a black leather, biker outfit, he was very muscular, had tan skin, roundish eyes and body, and had dark sunglasses. To complete the look, he had full-on combat boots, an inch off the ground. He looked at the detective expectantly. "Well?"

Conan sucked in a breath. "Sentomaru-san said that you were the one who first established communication in my world, but due to conflict of interest, you went hiding from the World Government and ended up here. Ivankov-san said you were a traitor, capable of the worst kinds of deeds. I hope you'll be honest with me, regardless of what kind of person you are."

"A good answer, it's nice to meet you, Kudo-kun." The man nodded.

"Good to meet you too, Dr. VegaPunk."
