On an island in the calm belt, a young boy lies on the sand.
"Oh my head, is this what a hangover feels like... wait minute, I don't drink!"
He looks at his surroundings, "WHAT.THE.FUCK! Why am I on an ISLAND! and why am I tiny!.... and scaly!"
He looks around his surroundings only to see an endless calm ocean.
". . . WHAT THE FUCK! Why am I in the ocean!"
Suddenly, a coconut falls on his head 'thunk'.
"AH! son of a bitch!"
The coconut splits open, revealing a note that says 'congrats, you've been chosen to be reincarnated in the world of One Piece, and where randomly given powers from a fictional character, you must be super lucky since you got Godzilla.'
"What the fuck?"
He gets up and walks to the water to see his appearance. He sees that he looks like a tiny humanoid Godzilla, he has scaly skin on his outer arms and legs as well as gills on his neck and a tail, and the icon back spikes.
"Okay, pros and cons of this situation. Pro, I'm Godzilla, therefore I'm OP as heck depending on which Godzilla I am, since some can fucking tank black holes, suck it, black beard.
Con, I'm in One Piece and I'm a rare race, or in this case, the only one of my race; therefore, I'll either get captured as a slave or experimented on, probably both if I'm ever caught by the World Government.
Con number two, I dont know much about One Piece... scratch that, I know quite a bit, but nothing that'll help me in this moment, damn.
Pro number two, this world has lots of waifus, but I dont know what time period I'm in. For all I know, I could be in the Rogers era, and I'm in the calm belt, which is full of Sea Kings. Luckily, I have gills, but unlucky since I'm in the godamn calm belt!"
Without him realizing, a sea king rose up from the water behind him, ready to eat him
'ROOOAAAAR!!'
Then, on instinct, he shouts
"SHUT UP!! I'M TRYING TOTHINK!"
The Sea King gets scared and immediately scrams
"Huh, oh shit, that was a sea king. Wait, did I just use conqueror's haki?... huh, that kinda makes sense, since if I'm Godzilla, which means I'm a king, since almost all godzillas were in a way dominant kings who conquered all, nice, welp, guess I should explore this island since I'm probably gonna be here for a while."
He then gets up and starts walking around the island
"Tree, tree, bush, oh look at that more fuckin tree, oh let's not forget the huge ocean surrounding me, ok that's my B for expecting much from this place, oh wait, look a ship wreck... SOCIAL ACTIVITY!"
He goes inside only to find skeletons
"Oh damn it, just dead people great, hmmm, judging by the size and color, plus the very obvious marine symbol, I'd say I'm on a wrecked marine ship, yep, definitely... welp time to see if there's any good loot ehehheh. 'loot goblin mode activate'"
He now proceeds to sift through the wreckage, looking for anything of value
"Welp, let's see, treasure, jewels, weapons, books, oooh, a devil fruit encyclopedia, a captain's log containing info about how corrupt they were, aka future blackmail material maybe, and a tiny chest which may or may not contain a devil fruit."
He flexes his fingers, shattering the chest in his hand
"Oh shit, I forgot I was strong as fuck, makes sense now, let's, which devil fruit are you?"
He grabs the Devil Fruit encyclopedia and starts looking for the matching picture, and flips through for a good minute before finally finding it
"Aha, there you the Mori Mori no mi but wait isnt this green bulls devil fruit how did it end up here, hmm well it was never mentioned or maybe i didn't read about how he got his devil fruit so maybe he ended up here at some point and ate the devil fruit welp to bad for him its mine now but wait do i really wanna eat this fruit hmmm, ill think about it but to be honest i dont even wanna be a pirate or even a marine i mean fuck all that crazy shit who would want all that stress man maybe be like a gardner or some shit and i mean i do have the perfect fruit for it but then i'll be weak to water and i'm a freaking godzilla for crying out loud i can't be weak to water i mean i'd still be able to breathe underwater but not swim which now that i think about it vegapunk said devil fruit are born from human imagination and desires, so i guess the weakness to the sea comes from humans innate fear of the unknown and the sea is the biggest unknown thing so maybe i can some how get rid of that weakness i mean after all i got nothing to fear from the sea i'm freaking godzilla king of the fucking monsters"
He then gets up, while still holding the Devil Fruit
"Hmm, let's try something here, HAAAAAAAAAAAAAAAAA"
He then proceeds to use his conqueror's haki on the devil fruit, focusing his sheer will onto it as he pushes more and more. He feels something push back.
"SCREEEEEONK!!!!!!!"
Slowly but surely, the will of the Devil fruit gets weaker and weaker against the constant assault of Conqueror's Haki until finally there's no more push back
"Ha, there we go, now there should be no more weakness, welp, bottoms up, oh boy, this is gonna be a hassle."
He then takes a deep breath and takes a bite
"UGHHHH yep this is disgusting oh god it's terrible"
He finally manages not to barf and swallow it
"Ugh, thank goodness, I only gotta take one bite, ugh, maybe the reason they taste so bad is because they were made from humanity's imagination, okay, time to test if my theory was right."
He walks to the edge of the beach and walks into the water, waiting to see if he will feel weak
"Huh, nothing happened. Nice, I can still swim and use devil fruit powers, now let's test out the Mori Mori Fruit."
ONE YEAR LATER
"It's been about a year, I think, since I arrived in this world, but it's kinda hard to tell since I have no concept of time, heck, I dont even know my age, but I wanna say I'm now five, I've gotten pretty good using my devil fruit abilities, i'm probably better at using it then Green bull but then he wasn't shown much so well see but, i can proudly say i've mastered quite a few a abilites, hell i can make any fruits and vegtables i want including hybrid plants, i even found out i can make some toriko ingredients i've hypothosised two reasons can do this is either because i know about plants that dont exist naturally in this world or because of that crossover event that will happen with one piece, toriko and dragon ball, anyways moving on.
I've sadley had little luck when it comes to my atomic abilites which i suspect is due to my young age at most i can only do a small puff stream like minilla and maybe also due to that, i don't have enough radiation in my body which i can guess due to the color my spikes give off is only a light green unlike most godzilla who usually have a blue tone, so until i can find a source of radiation or until i get older those abilites will have to be shelved, but that hasn't stopped me from training i may not want to be involved but that doesn't mean i don't have plans to become strong after all in this world, only the strong survive.
Therefore, I've been training my body by fighting all the Sea Kings in the calm belt, at first i started by fighting only the surface dwellers then as i got stronger i went deeper to fight stronger ones, its been a up hill battle due to my young age but, i can feel im much stronger than most well more than usual for one, due to constantly eating good food, two i've been fighting strong oppents this entire time, and three i've been tempering my body by constantly going into deep waters facing the crushing pressure of the ocean, and four i've already come quite far in haki due to all of these factors, my armament and observation haki have already advance quite far i can already coat my body with armament, but my observation haki is where i shine, which i suspect is due to Legendary godzillas ability to basically scan and sense the entire planet which he inherited from mothra when she sacrificed herself for him, so im basiclly omnipotent."
ZZZZZTTTT
"Hmm, how interesting, looks like I'm getting a special guest, well then let's see how well I do against that old Monkey."
VOOOMMMM
