Zoro had just made his way back onto the top deck, looking around for Franky to show him who was the REAL super guy around here when the entire ship suddenly rocked back and forth, nearly tossing Usopp (who had been fishing) over the edge. Likewise, below deck, Sanji had nearly spilled a vat of soup all over himself due to the shaking which also caused a multitude of vegetables to go spilling onto the floor. Zoro was able to easily keep his footing thanks to his larger size and more stable body mass. He quickly ran over to the side of the ship where Usopp was slowly getting back to his feet and peered over the edge of the ship. The water was calm and serene. It was incredibly unlikely that any sea creature had slammed into the boat. His eyes scanned the horizon, looking for any sign of an enemy ship. Nothing. Still, it didn't hurt to be sure! With a swift movement his meaty fist enclosed around Usopp's collar lifting the cowardly man into the air, Zoro's fierce eyes staring into his own.

"Z-Zoro?! Is that you?" Usopp managed to squeak out, his feet kicking wildly in the air.

"Yeah, yeah, but shut up for a second!" Zoro ordered, tightening his grip. "Did you see anything that could have caused that shaking? A sea king? A ship? Anything like that?"

"N-No! Nothing! I didn't even have a bite on my line!" Usopp rattled off, trying to free himself from Zoro's grip. "Now let me go!"

"Feh. Fine." With a casual flick of his wrist Zoro sent Usopp flying into the mast. With a sharp crack he was knocked unconscious. Zoro couldn't help but smirk, flexing his arm, his veiny bicep erupting from the thick appendage. "Damn! I wasn't even trying! Guess I really don't know my own strength!"

He chuckled before cracking his knuckles and moving towards the lower decks. Whatever caused this was probably down there. "Maybe Chopper finished the next dose for me!" He thought, a dark grin slowly stretching across his face. All of this power was starting to go straight to his head.

Zoro's shoulders scraped somewhat uncomfortably against the walls on either side of him as he moved into the lower decks of the ship. "Nnngh...I'm going to have to get Franky working on expanding this ship as soon as possible!" Zoro had grandiose plans for the Thousand Sunny and the whole Straw Hat crew. Although now that he was captain they were going to have to change the name. He'd come up with something later. Right now his mind was preoccupied with the idea of a massive war ship, something that would strike fear into the hearts of anyone who would oppose him as he took his place as the greatest swordsman in the world! And why stop there? As long as he had Chopper mixing this formula he would keep getting stronger and stronger until the whole world would be under his command! The World Government was already beginning to weaken in this New Age of Pirates. Why not put a pirate in charge? And why not make it the biggest, strongest one of all? Zoro grinned as he began searching the lower decks, kicking open any door he came across, a few of them breaking off their hinges.

Chopper heard the heavy footfalls of Zoro's boots as the muscle bound swordsman slowly made his way closer to him. Panicking, he turned to his Heavy Point and started laboriously dragging Luffy over towards the closet. If Zoro saw Luffy in this state he would surely be angry and the subject of that anger...would be him! With the crunching sound of heavy wooden doors being forced off their hinges filled his ears, Chopper managed to pull up as much strength as possible and shove Luffy into a closet, barely managing to shut the door before Zoro burst in. Chopper jumped, reflexively shrinking back down to his normal form as Zoro widened the door frame with his broad shoulders, splintering the wood on either side of him as he walked slowly inside. Chopper gulped, his knees shaking as he stared up at this looming mountain of muscle before him. Luffy, while a few inches bigger and nearly twice Zoro's mass, was not even half as terrifying as Zoro whose face made it clear that no games would be played with him.

"O-Oh! H-Hey Zoro!" Chopper said, trying to sound cheerfully optimistic. "W-What's up? The potion isn't...isn't quite ready yet!"

Zoro's cold gaze fell onto Chopper as he walked up to him, barely able to see the little reindeer creature beyond his thick pecs. Chopper cowered in Zoro's shadow, his legs feeling as weak as wet noodles.

"Do you know what caused the ship to shake like that?" Zoro asked.

"Shake? What? Shake? What do you mean? Shake? I have no idea what you're talking about...shake?" Chopper babbled.

Zoro rolled his eyes and said, "How much longer until the potion is ready then?"

"Um..." Chopper glanced back at his equipment. Technically he had all the separate ingredients ready except for the concentrated dose which he would need to remake so it could all be done in about ten, fifteen minutes. "Soon!"

Zoro smirked and said, "Good! You're an invaluable member of this crew Chopper! I'm counting on you."

Chopper chuckled, suddenly forgetting his fear as he heard the praise. He was a sucker for compliments. It made him feel special~ Obviously Zoro knew that and with guys like Chopper it was better to be loved than feared. "Don't worry Zoro! I'll have it done really quick for you!"

"Keep up the good work kid." Zoro said, waving a little as he headed out the door.

As soon as Zoro's crushing presence was gone Chopper suddenly realized what had just happened. "Ooooh! I can't believe I fell for that!"

He almost opened up the closet again before remembering how Luffy was set up in there. If he opened the door the gigantic captain would tumble down onto the floor, shaking the ship once again! "Well...he'll be fine in there! I hope he wakes up soon though! He's the only one who could stand up to Zoro!"

Chopper went back to his duties, wondering what the extent of this once seemingly harmless experiment would be.
