Episode 4: Battle at Arlong Park! Rage That Transcends Reason?!
[Third Person]
Nami felt... she didn't know. She wasn't sure. She wanted to cry so badly as she felt the straw hat on her head. Heck, she did cry.
Luffy... Even after all she'd done, after all she'd said... He still wanted to help her this much, without any hesitation. Nami knew how much Luffy treasured his straw hat, and to give it to her... It was such an immense sign of trust.
Nami didn't feel like she deserved it, and yet it had been given with almost no hesitation.
Luffy, Zoro, Usopp, even Sanji had walked to Arlong Park to fight. To fight for her. The ones she betrayed, like she had so many others.
Was this... what having true friends was like? She wasn't sure but... She wanted it to be true. She wanted it to be true so badly.
"oooooooarh!" Nami was broken out of her thoughts by a distant cry. And it was coming closer, rapidly. "ooooooOOOOOAR!"
Rounding the corner of a building rushed a person with the most vividly red hair Nami had ever seen and cold blue eyes that caught Nami's attention. They radiated more anger and rage than Nami had ever seen in her life.
That and they were tied to what looked like a broken mast. That was... something, to be sure.
"OOOOOO- huh?" The person skidded to a halt right by her and stared at Nami with those cold eyes. "You! I know that hat! Where is he?!"
Nami blinked, not sure what to feel right now. This person was obviously looking for Luffy. '"Uhh..." An intelligent and informative answer, truly.
"I ASKED WHERE THAT RAT BASTARD WENT!" The red-head screamed at her face before something weird happened. As if snapping from a trance the red-headed person flinched and backed off a bit, eyes widening. The anger in those eyes was gone, like smoke. "Wait... aren't you... You're Nami, right?"
"Uhh... yes." Nami manages to reply. She follows the stranger's gaze to her injured shoulder, still bleeding from her stabbing that detestable tattoo that had tarnished her skin for so many years. The red-head's brow furrowed.
"That knife. Cut these ropes." They turned and gestured at the ropes tying them to the broken mast using their head.
"H-huh?"
"Just cut the ropes! It's not a complex request!" The red-head snapped at her.
"Ah, yes. Wait." Nami muttered and used her good arm to cut the ropes as fast as she could. Soon enough the ropes gave away and the mast fell to the ground with a loud thud.
"Wheew, thanks for that!" The red-head said, rolling their shoulders, elbows and wrists. Immediately they started to sprint off, but stopped and returned. They grabbed the broken mast and lifted it on their shoulder with ease. "Still taking this. Got something to do with it. Where is Arlong Park?"
Nami, a bit flustered at the time only pointed at the direction. The red-head nodded and was about ot run off again before stopping, again. They looked back with a grin showcasing very familiar looking rows of sharp teeth. Just like his. The sight unnerved her somewhat.
"Oh, by the way. Should really consider cutting the habit of playing with knives. It'll really slice years off your life if you take a stab at it- oh fuck me, I'm so mad I'm punning! GOD DAMNIT! LUFFYYYYY!"
And the person with red hair sped off towards Arlong Park, leaving behind a somewhat confused Nami.
"... Who the heck was that?"
[First Person, Megalon]
Okay, was probably not thinking very straight if it took me a bit to recognize Nami. At least that sobered me up a bit but I'm still mad as hell! All that did was help me focus a part of my anger to that other motherfucker.
I ran at full speed, the broken mast on my shoulder. I'd thought of some use for it now that it wasn't being a stupid training weight. A kind of ironic vengeance, at least for me. But first I needed to get there before Luffy starts anything. I refuse to miss this fight, damnit!
I can already see Arlong Park and pick up speed as I ready the mast. The gate has been busted open, Luffy's doing. So at the very least he has punched Arlong in his prick face already. The mere thought of missing out on all this is kindling the fire that is my anger.
When I am close enough I begin my entrance.
"LUFFFYYYYYY! SANJIIII!" I scream at the top of my lungs as I see that red-vested rat and the blond-haired prick on the other side of the gates. I ignore the large amounts of people, inhabitants of Cocoyashi as well as Johnny and Yosaku, and jump straight over them with a superhuman leap.
"Megalon-aneki!" I faintly hear Yosaku exclaim in surprise by the gates, but I am too busy. I spot Luffy, and he is turning towards my voice. Perfect!
"YOU BASTARD!" I scream bloody murder as I swing the mast down onto his head, smashing his rubbery face into the ground. The impact left a nice crater behind. God damn I love being strong! "THAT'LL TEACH YOUR JERK FACE, JERK!"
No one had expected me, so I drew an array of reactions.
Usopp was shrieking in terror that I had just assaulted Luffy out of nowhere. Zoro's hands were at his swords, registering me as a threat(I'm honoured). And then there was...
"Megalon-san?!" Sanji exclaims in wide eyed surprise. I immediately lift the mast and swing it again, slamming him in the face with it. He flies a bit back before hitting the ground face first. I know he is tough enough to take it.
"ONE FOR YOU TOO, JACKASS!" I yell at the top of my lungs. "HOW DARE YOU TWO JUST DITCH ME! DO YOU HAVE ANY IDEA HOW MAD I AM RIGHT NOW? JUST MOMENTS AGO I WAS READY TO KILL YOUR BETRAYING ASSES!"
"Hpmh, another human-" Arlong pipes up and I reflexively throw the mast like a javelin at his prick face, sending him flying to the wall surrounding the park, like Luffy did with his punch before I showed up.
"YOU STAY OUT OF THIS YOU FISH FUCK! I'M COMING FOR YOU IN DUE TIME, SO SIT YOUR ASS DOWN AND SHUT THE FUCK UP!" I voice my displeasure at the sawshark fishman. The rest of Arlong's crew gape at my anger. That, or the fact I had the gall to strike out at Arlong so casually that it was close to an afterthought.
"... What the heck is going on?" Zoro asks, clearly no knowing what is going on.
"AAAH! It's another monster!" Usopp shrieks in fright. I send a toothy scowl his way. "AAAH! IT IS A MONSTER!"
"YOUR NOSE IS A MONSTER, DICK!" I shoot back at him.
Luffy get's up from his own personal crater and dusts his clothes. He doesn't even look like I hurt him that bad(which frustrates me). Then he sees me. "Oh! Hey, Megalon!"
"Don't you 'Hey, Megalon!' me like nothing happened! You rat-brained fuckers ditched me!"
He tilts his head to the side. "We did?"
"I was tied to the fucking mast, remember?! Come on!"
"Would somebody please tell me what's going on." Zoro speaks up, eyeing me warily.
"That's... Megalon-san. She's part of the crew." Sanji says, getting up while holding his head. "Sorry, we... might have gotten a bit sidetracked."
"Oh. Sidetracked? That's your excuse?" I growl venomously. "Be glad I ran into that Nami chick or else all my anger would be on your sorry asses and you'd be DEAD!"
"Ah! Sorry, we kinda forgot." Luffy says unhelpfully.
"THAT'S EXACTLY WHY I'M MAD, YOU MORON!" I snap at him.
Zoro keeps looking at me funny. I hate it. "So you're an ally?" I make an attempt to relax my posture and stand straight while returning his look with a glare of my own.
"Name's Megalon Grandwhite, and against these fish-bastards, yes. After that, I might beat Rubber Boy and Curly Brow senseless if I feel justified or unsatisfied enough after this is done." I say as calmly as I can. Which is not much.
After a moment of sizing me up, he relaxes a bit. "Sounds reasonable."
"Yosh!" Usopp gives me a thumbs up. "Nice to have another guy on my team!"
"Girl! I'm. A. Fucking. GIRL!" I snap my jaws at him. He cowers in fear. Pussy. I crack my knuckles and let a feral grin dominate my face. "But anyway. I'm glad I made it in time. I didn't want to miss the fight."
"You've got some nerve." I turn just as Arlong is climbing out of that rubble pile I sent him to, looking insultingly unaffected by a mast-to-the-face. "Barging here and giving me orders." He notes my teeth and his eyes narrow. "You bear fishman blood?"
"As if I'd want to be associated with the likes of you even if I did." I sneer at him. "I'm one hundred percent human, fish-dick!"
"Makes little difference then." Arlong scoffs. "One more human will not change the fact that you will die for standing against us fishmen."
And the condescending supremacist bullshit begins! Well fuck you, I'm part shark! Come to think of it, doesn't that make me a sort of pseudo-fishman?
... Nah, probably not! Can't even go hybrid, so fuck me I guess.
I glance at Luffy. "I take it you want that sharp-nosed asshole, right?" He nodded. "I'll just assume everyone else is free game. Should warn you though. I'm pretty fucking livid right now, so I can't promise I'm able to fully control myself."
"You think pretty highly of yourself." Zoro speaks up, eyeing me. "But do you have the strength to back it up?"
I flash him a predatory grin. "You'll see soon enough, Roronoa Zoro." I allow my grin to turn into a borderline psychotic smile. "After all, it was I who defeated Don Krieg with a single strike." I was hyping it up a bit, but it was still practically true so I didn't care.
"Y-y-y-you beat Don Krieg? IN A SINGLE STRIKE?!" Usopp exclaims, looking both amazed and horrified that he was in the presence of yet another monstrously strong individual. Poor guy just can't catch up.
Zoro was suspicious. "Luffy?"
"Yup." The Straw Hat confirms my words. "Megalon is really strong."
Ahh~, my ego! Such large presence you have!
"Good enough for you, Mr. Moss Hair-"
A lone fishman seemed dumb enough to try and charge me while I wasn't paying attention. He was sorely mistaken and I backhanded my fist into his face and rocketed his ass straight into the ground with a crack. I don't know if it was the floor or the guy's bones. And I made it look like I barely tried.
I sent one of my most potent glares at the rest of the fishmen and growled through my teeth. "Haven't you been taught it's basic manners to not interrupt someone in the middle of a conversation, sea food?"
Hypocrisy aside, my terrifying presence has a notable effect on the fishmen, save for Arlong and his three strongest men: Hachi, that weird lip-guy whose name I can't bother to recall and Kuroobi.
Arlong seemed highly displeased that a mere human made his fishmen shiver in their boots. Kuroobi and the weird lip-guy seemed unimpressed. And Hachi... Well, Hachi was not the smartest. He laughed and stepped to the side of the pool in a confident stride.
"You guys are idiots." Says the real idiot. "You think Arlong-san will waste his time with the likes of you?! He'll be enough for the job!" And then he blew some sort of call from his tube-like mouth. I allow myself to grin widely. I knew what was coming up.
The ground began to shake and, as if a tidal wave was approaching, the sea beyond the seaside gates of Arlong Park began to rise as something approached through the waters .
"You guys can be his next meal!" Hachi exclaimed. "Come on out! Mohmoo!"
And lo and behold, out of the pool emerged a rising pillar of water, cloaking the creature within.
"It's... It's a monster!" Usopp cries pathetically. "The monster from the Grand Line that crushed Goza Village!"
Then the familiar form of a green-spotted sea cow emerged, looking absolutely pathetic with a bruised face and a big bump on his head. Almost makes me feel sorry for him.
"It's huge!" Usopp shrieks in fright. I take it as my duty to knock him upside the head.
"Be quiet. It's annoying." I say to him and take a few steps at the sea cow, waving lazily at him as if greeting an old drinking buddy. "Oi, it's been a while!"
Mohmoo lays one glance at me and in an instant I see a look of dread in his eyes as he cries fearful tears. Memories of me utterly dominating him no doubt flashing back to his mind, he just turns to leave.
"HEY, YOU DARE RUN AWAY NOW? MAN UP AND FIGHT ME!" I scream after him, feeling somewhat insulted.
"You wanted to fight that?!" Usopp cries in shock at my apparent lack of self-preservation.
"Wait, Mohmoo? Where are you going?" Hachi calls to the fleeing sea cow. It does not seem to be working, his desire to be far away from me trumping all loyalties.
"Mohmoo... What are you doing?" Arlong speaks with eerie calm as Mohmoo stops in his tracks. Guess he fears Arlong more than me. I take offense to that. "Well, if you want to run away, I won't stop you... Would I, Mohmoo?"
With fear now overriding all hesitation the sea cow turns and charges us, some fishmen joining in the attack at our little group.
"It's coming!" Usopp scream in panic.
"Hell yeah, about time!" I pump my fist, ready to fight.
Zoro prepares to draw his blade, Sanji smirks while Luffy is all ready to act, stepping forward.
"I'll take care of it! This is a waste of time!" And then he sinks both his feet into the stone flooring.
"... What." I say in dull bewilderment.
"What the hell is he gonna do?" Sanji questions.
"I've got a bad feeling about this." Zoro says.
With Mohmooh and the fishmen charging Luffy, he spun his torso around many times in a way only someone made out of rubber could. Then he extended his arms to grab Mohmoo by the horns and... wait... Why does it feel like I am forgetting something?
"Oi, run!" Zoro says quickly.
"What? What is he gonna do?" Sanji asks.
"I dunno but it won't be pretty!" Zoro says as the two run off. I turn to their direction in confusion.
"... Whaaaa-" I drawl out slowly, wondering what they are so scared about.
"Gum-Gum..." Luffy screams. My eyes widen as I remember! "Windmill!"
Luffy lifts Mohmoo's massive body and then spins it in a circle, hitting the fishmen, the main building and, because I am slow and forgot this was a thing, I too got hit by Mohmoo's hulking body.
"Gaaaaah!" I screamed as the sea cow crashed into me, knocking the breath out of my lungs and I stuck to his body because of centrifugal force and got spun around too. It was dizzying and a bit sickening. Just before Luffy released and threw Mohmoo back into the sea I slipped out of that spin and it flung my ass really high in the air.
"GOD DAMNIT, LUFFY!" I screamed furiously as I gained altitude. Normally this would be a good time to transform, but I was above land and the landing would've hurt like a bitch and I'd also become a sitting duck with how big I was. So I was left with the only option I had, as per laws of physics.
Scream loudly as my ass stopped ascending and begun to rapidly descend back down. Right at the Arlong Building. I crashed right through the top spire, went right through the ceiling and the numerous floor on the way down before everything came crashing down onto the bottom level. My landing sent a tremor through the earth and made a big crater.
And let me tell you, if I didn't have Zoan durability I'd be out cold, likely even dead from egregious internal damage. Everything hurt like a bitch. I think I got a several broken ribs, my back feels like absolute shit and I'm pretty sure I landed on my left arm, so that is likely broken too. I think I might be bleeding from places. I may also have taken a solid blow to the head when my skull connected with the floor, so I might have a concussion. Maybe.
I don't know for how long I just lied there and grit my teeth at all the pain in my everything. I didn't cry, I was too badass and proud for that, but that didn't make it hurt any less.
But I was conscious. I was alive. And more importantly, I was pissed! Pissed enough to ignore all the signs of my body just wanting to stay the fuck down. I pushed myself up with a growl. I used my right arm - lefty was definitely broken with how limp it was – and got onto my feet and began drudging my ass towards the front door. Which I kicked off it's hinges, along with some of the surrounding wall, with an angry shout because FUCK THE DOOR!
I stepped outside with a dark look in my eyes and a vicious snarl on my lips, my left arm limp at my side.
"Megalon?!" I heard Sanji exclaim and based on his tone I was presuming I must've looked pretty bad.
"Oh, you're still alive." Arlong noted condescendingly. I ignored his prick face for a second to see what exaclty I had missed.
Usopp wasn't here, must be fighting that weird fishman elsewhere. There was Zoro and Sanji. Kuroobi and Hachi were still here, as was Mr. Fish-Fucker... Wait...
.. Oh no... No...
I felt something primal within me stir and I clutched my right hand into a tight fist. "Sanji," I spoke quietly as my eyes narrowed dangerously. "Where is Luffy?"
"Luffy..." Sanji said with a grimace "He was-"
"Shahahahaa!" Arlong laughed cruelly and spread his arms wide in an almost theatrical fashion. "That Devil Fruit eater is down in the sea, a grave he deserves! Shahahaha!"
My eyes set on Arlong, laughing like the heartless monster he is. My insides felt like they were burning with the anger- no, the pure rage I was feeling as he continued to laugh and laugh. My whole body shivered and trembled as that rage grew, and grew...
I don't know what came over me, but I began to chuckle softly.
Arlong stopped laughing and sent one of his condescending looks at me. "What is this? So afraid to die you cannot do anything but laugh? Seems you finally realize the futility of your efforts, human."
"...he...heheh...hehehehe..." I chuckled a bit more before it suddenly grew into a full blown laugh. A loud laugh. A mad laugh. A distinct laugh. "Samemememe! Fear? You? Is that supposed to be a joke? You are such a FUCKING comedian! Samememe!"
Then I feel that primal sensation. As I continue to laugh I could feel my muscles tense up and shift. I felt myself growing in size and stature, my body morphing into a new shape. I felt a dorsal fin sprout from my back and my teeth growing along with my jaw as my head restructured itself. And as I did all this, I hear my laugh grow deeper and deeper until it sounds borderline masculine and manly.
I felt all eyes on me, even Arlong's. I can see a look of shock as he grows smaller and smaller from my perspective. And that is the last thing I see before my brain just shuts down.
[Third Person]
Sanji was a cook of the sea. He had seen and heard some pretty unbelievable things over the years, but sometimes things just surprise you. One of those things was the first time he saw Megalon transform into that massive shark – a creature big enough to drag Baratie under by itself – to take Krieg on. And while she didn't use it much in the actual fight, Sanji could tell that Megalon could have theoretically smashed into Krieg and taken him and the Baratie in one decisive movement.
There was no doubt in his mind that Megalon was a powerful lady. A crude, anger-prone and impulsive lady. But what he bore witness to made him lose his cool.
He knew some things about Devil Fruits, such as that the one Megalon used was a Zoan type. He had seen her in her Shark Form, but not in any kind of hybrid form that all Zoan users possessed. She had even briefly mentioned, while bored, that she hadn't managed to transform into it yet while on their way to Arlong Park.
But Sanji was absolutely sure that was exactly what was happening at this very moment.
Laughing madly like something inside her had snapped and broken, Megalon began to change. The change was slow, taking place over the course of seven seconds that seemed to drag on forever. Her form grew larger and more muscular, her head took a more shark-like shape and more or less fused with her body, her mouth and jaws grew bigger and wider along with her teeth and a large arching dorsal fin grew on her now hunched back.
When it was all over, in the place of Megalon stood a monstrously giant figure. It's body proportions were a bit off with smaller, short but thick legs and long, excessively muscular arms. Arlong was pretty tall and big, but he looked absolutely tiny in comparison to the hulking monstrosity. It was three times Arlong's height, him reaching only it's hip. The hulking shark-thing had dark grey hide, with white on the front of it's body starting from the lower jaw.
If Sanji didn't know better he'd think it was just a massive shark fishman, with emphasis on the man. While she was transforming, Megalon's laughter began sounding less and less like herself, and now it sounded like a deep-voiced man was laughing in her stead.
"Megalon... san?" Sanji asked himself weakly. The hulking figure had all the same clothing, as they changed along with the user to fit them. The same tank top, the same patterned cargo pants, the same sandals and the same bandages she wraps around her arms and knuckles. Even he could barely recognize her, and he saw it happen right in front of his eyes. The change was so drastic.
"Oi, what the hell is that?" The Marimo asked, hands at his swords.
"Megalon-san is a Devil Fruit user." Sanji explained. "Although... something feels very off about this."
Arlong was shocked by the drastic change that had taken place. Instead of a frail looking human now was... that. A mockery of a fishman! "You... You ate a Devil Fruit as well. Who are you?!"
Then the massive laughing giant shark-man stopped laughing and inclined its head to look at Arlong. "I ARE..." The man-shark spoke in a loud, rumbling voice as it raised its massive fist and Arlong knew he had to dodge. He jumped out of the way of the relatively slow punch that exploded and obliterated the floor he once stood on. "SAMEHADA!"
Arlong grimaced. This thing was powerful, extremely so. It drew back its fist and let out a bellowing, feral roar.
This thing was dangerous.
"Well, looks like Luffy wasn't lying. She's really something." Zoro said.
"... No, something is wrong." Sanji said. "Look closer."
"Huh?" Zoro asked. "What are you talking about?"
"Her eyes..." Sanji said, pointing at the massive brute. Its eyes were stark white, lacking any signs of intelligent or rational thought. They were the likes of a shark during a blood-frenzy. "I don't think Megalon-san is quite herself right now."
Zoro seemed to get it, a hands going to his swords. "Which means, we ought to be on our guard."
The man-shark roared so powerfully that for a moment you could've thought that the air reverberated with it.
Kuroobi took a fighting stance and readied himself. "This is quite a surprising twist of circumstance. No matter. We must defeat this adversary. Mere size does not equal strength!" He then charged the massive man-shark. "I'll show you the power of my Fishman Karate!"
"Wait, Kuroobi-san!" Hachi yelled after his comrade.
"Fishman Karate," Kuroobi begins his attack and jumped high enough to be on the massive man-shark's chest level and struck its chest with his fist. "Hundred Brick Fist!"
The attack landed fully, but had no other effect than making the man-shark flinch slightly. Kuroobi stared in wide eyed shock at how little the technique accomplished.
He was so shocked he didn't notice the massive fist that struck him. The punch held massive power behind it, pounding him straight to the ground below with a large earth shaking crash. When the fist was lifted, Kuroobi was beaten and battered, barely conscious. And even that left him when the fist descended again. And again.
Sanji, Zoro, Hachi and Arlong could only stare with varying levels of shock as the massive man-shark continued to pummel the unconscious Kuroobi with its right fist, stuck in a state of violent frenzy. The left arm clung limply to its side and slightly flailed with each strike.
A scream came from one of the citizens by the gates, and immediately the man-shark's fist stopped mid-punch.
"... Oh hell." Zoro spoke, having a really bad feeling. His worry was proven justified when the man-shark turned its mindless eyes at the group of people behind the fallen gates. Then it roared and turned. "Oi, seriously?"
"Megalon-san, don't-" Sanji tried to shout at the frenzied being.
"That won't work! She's beyond our reach right now." Zoro said gravely, drawing his swords. "You should quickly see about Luffy."
"Oh, shit! I forgot about him! But... Megalon-san..."
"I'll take care of it." Zoro said firmly. "Now get going!"
Just then the massive man-shark moved in a slow half-run, straight for the citizens of Cocoyashi Village. It let out a feral roar as its lips drew back, revealing its teeth in their full deadly glory.
It was also when Zoro zoomed at it, all three swords – two in his hands and one in his mouth – ready. He placed the two blades over his mouth blade in a formation and spun them in his hands while he ran. He didn't like the idea of using this on an ally but... this situation left little options. This thing was extremely strong and dangerous, so he knew he had to end it fast.
Zoro jumped to meet the man-shark midway.
"Santoryu Secret Technique: Three Thousand Worlds!" He passed the giant man-shark in an instant. The massive being took a few more slow steps before stopping dead on its tracks. Three large gashes appeared on it's right side and right arm and the man-shark bellowed – in rage or agony, Zoro couldn't tell.
What he could tell was that cutting that man-shark's hide had taken more effort than he had anticipated. The thing had thick skin, he gave it that. But before he could do anything more he winced in pain. Using that technique and the extra effort he had to put into it had opened up his old wounds from his fight with Mihawk.
That would be an annoyance.
But what about the girl wearing a monster's skin? The massive man-shark had been quiet. As in absolutely silent. Zoro turned just in time to see the man-shark fall on its knees before the rest of the body followed, slamming into the ground with a tremor and setting off a cloud of dust.
When it began to shrink and shift back into the girl – Megalon, Zoro recalled her name – that Zoro knew he'd succeeded in stopping a rampaging monster from harming the villagers. A job well done.
But that left him to deal with everything else. That bastard cook had done as ordered and likely went to see if Luffy was still even remotely alive while he was left with the octopus fishman and Arlong.
Zoro grinned. He could take those two, he bet. He did, the octopus at least, before his injuries got the better of him.
It didn't take long after for Luffy to reveal that he was alive, freed from the sea bed by Sanji and kept alive and breathing by Genzo – the village's leader figure – and Nojiko – Nami's sister – and the Straw Hat fought Arlong by himself. He'd prove his friendship towards Nami and his dedication to have her in his crew by defeated Arlong with an attack that completely leveled Arlong Park.
The Straw Hats had won.
But now they were left with the severely bleeding and unconscious body of the red-haired, foul mouthed and highly temperamental girl with three deep gashes in her right side and arm.
Her fate lied uncertain.
Episode 4
Fin~
Next Episode: Awaken for the Aftermath! Goodbye Cocoyashi!
A/N: Of course, being the Main Character with ridiculous and obligatory Plot Armor, she will survive. Now for some interesting ~Trivia~!
And it's about Megalon's forms! [*Off-screen cheering*]
An estimated size of a real Megalodon ranged somewhere from 15 to 18 meters in overall length. Megalon's full Megalodon/Shark Form is much larger, a whopping 25 meters long. This makes her much bigger than Going Merry, and maybe even Thousand Sunny, and makes it correct to classify Megalon's Shark Form as a lesser Sea King. Her rough hide is thick and rubbery enough to stop bullets and can take direct cannon ball fire. In this form Megalon is at her strongest point while in the sea. (The form is also utterly useless on land, obviously.)
Her hybrid form, debuted in this very episode, is approximately 6 meters tall, muscled as all fuck and sounds like a macho, grizzled man. It has no tail. It is slightly bigger than Chopper in his Monster Point. If you want some sort of visual aid, think along the lines of Street Sharks. And, as it is seen in this Episode, it can be quite vexing to control, especially while angry. Its hide is thick enough that cutting it with a sword takes some extra effort. We don't know yet if this form is capable of swimming in any capacity. In this form Megalon is at her strongest while on land. (And it does not help people assume that Megalon is a girl. Poor gal.)
We also find out that Megalon now has her own distinct laughter, as do a large number of people in the One Piece-world. Hers is: Samememe! Same, of course, is the Japanese word for shark. Theming!
Fun – if fairly obvious – fact: Megalon's name is a combination of two shark species. Megalon is, of course, from the ancient and mighty Megalodon, while here surname Grandwhite is from still kicking badass of the seas, the Great White Shark. Two badass sharks equal our heroine who has confidence pouring out of her ears.
Also, no way would Zoro have taken her out that easily under normal circumstances, even using Three Thousand Worlds. Zoans are tough like that. But as it stood, Megalon was already quite damaged from the consequences of Luffy's improvised attack. Zoro just tipped the scales enough for it to matter.
Overall, this was fun to write, if only because Megalon is absurdly powerful for someone this early in the series. It's not even Grand Line yet! My justification is that Zoan powers are the most static of the Devil Fruits, so they give instant bonuses but are harder to develop further. But trust me, things won't always be this easy for her. No way Jose. This is One Piece, motherfuckers!
~Till Next Episode!~
