This is a list of silly, or Just for Fun wild mass guesses for the series One Piece. More serious entries should go in one of the open pages.Please add new entries to the bottom of the page.
Zoro secretly loves sappy romance musicThe zombie with his shadow had a shirt with the words ''Your Song'' printed on it. A famous Elton John song. Zoro keeps it a secret because Sanji would never let him hear the end of it.
One Piece is one peaSounds close enough to "one piece". Maybe people misheard Roger, who said "peas" instead of "piece", and calling the treasure "One Piece" instead of "One Peas" caught on.
Boa Hancock is based off of Megan FoxBoth are considered the most beautiful person of their world, are next-to-emotionless, and have this... squicky thumb problem. Doesn't help that their names can be taken sexual and are animal related. It's not too unlikely, considered many characters like Django and Donquixote are based off of foreign celebrities.
Portgas D. Rouge was a Bene Gesserit witch from DuneIf she was able to have such absolute control over her body, particularly the growth of her unborn child, then it's conceivable that she had special training. Her mission was to extend the line of the Ds in a gamble that one of the Will of D would become the next Pirate King and bring further changes to the era of Pirates.
One Piece is the after-afterlife of The Demon OroronSince Ororon was from the afterlife already, where would his spirit go after dying? It's clear that he didn't go to Heaven or Hell, so there must be a further afterlife - one where his spirit was reborn as Sanji. They both smoke; they both have dirty blond hair that covers one eye; they both wear black suits with boots (to compare, look here◊ and here◊; and they both have similar personalities. The only difference is Sanji's women obsession, which probably stems from losing the love of his life because he died. He tries to woo every woman he finds so he can have the relationship that he and Chiaki never got to have. The Devil Fruits are likely powerful demons as well; but they were not given a human body, but a fruit form which can transfer their powers to whoever eats them.
The secret of how the One Piece world gets babiesEvery seven years, all sexually mature One Piece characters go through Pon Farr, and have a mating frenzy, hence how this infamously No Hugging, No Kissing world gets it's babies.
Usopp is a descendant of Drosselmeyer from Princess Tutu, which why his lies come true.Okay, this just HAS to be said:
The One Piece is a Core DrillLuffy and crew will discover it, freak out over how it's just this tiny useless thing, and then notice the odd impression in the wall behind the chest. Luffy experimentally inserts the Core Drill, and cue Raftel Island (or perhaps some hidden "secret weapon" of Gold Roger's hidden within Raftel Island) activating and transforming into an enormous face-battleship. Thus the second chapter of the One Piece saga begins, taking the Straw Hat Pirates to the stars to fight for their claim to the title of King of the Spirates. I apologize for the horrible pun, and am fully ready to admit that I'm mainly saying this because I can't get the image of the Dai-Gurren-Dan crest sporting Luffy's hat out of my brain.
One Piece is the Pirate King from FLCLIn FLCL, we find out that the Pirate King can be imprisoned and that his power can be absorbed. It makes sense, then, that absorbing the Pirate King would make you the new Pirate King. This is exactly what One Piece is supposed to do. The next question, then, is if Naota is related to Gol. D. Roger. And did Gol. D. Roger ever fight with weapons he pulled out of his forehead?
Usopp is a Time-Lord, and the Merry-go was his TARDISThis is why it was so hard for him to let it go.
The World Government is run by The PatriotsIt would fit because of their similar desire to control information throughout the world and bring about "peace". The Void Century is the 100-year period that it took for the Patriots to reduce the world from the state of technology seen in the Metal Gear games to the low-tech seen in the One Piece Universe. They did this largely so that they could more easily control information without the threat of the Internet. They used their mass-produced Metal Gear RA Ys and a large number of nukes to blast the world into fragments and screw with the world's climate to create the Grand Line and the many islands throughout the world. Isolated islands were easier to control than unified countries connected by the internet. They genetically engineered the Transponder Snails themselves. They then circulated false information about the history of the planet and did their best to eliminate any information of the tech level that used to exist. However, the events of the Void Century were too dangerous for anyone to go into, so they left it blank. The Poneglyphs are incredibly dangerous for the Patriots because anyone who discovers the old tech could reverse-engineer it and use it as a weapon against the World Government and the Patriots. The "weapons" like Pluton and Poseidon are, in fact, various forms of Metal Gear; REX and RAY, respectively. As outlined in the Metal Gear WMG page, the ending of MGS2 was Raiden undergoing a psychotic break, which means that Arsenal Gear did not break down. Instead, the Patriots have it hidden. The last island of the Grande Line, Raftel, is no island; it is Arsenal Gear, kept in storage. As Raftel is also where Devil Fruits come from, it explains why the powers they give are so many and varied. The Fruits are full of Nanomachines, which means that they can have any number of bizarre, magical effects.
The World Government is run by TemplarsAnd the Poneglyphs are Pieces of Eden. Alternately, Roger collected all the Pieces of Eden and left it in "one piece". The Revolutionaries are Assassins.
The Grand Line is a Hellmouth.It would explain all the weirdness.
The world One Piece takes place on is Imperial.Look at the World Government for a moment. It's the Imperium of Man in miniature.
Boa will get into a Romantic Two-Girl Friendship with Tashigi, except not really.Think about it: on Amazon Lily, "Strength is beauty." By the end of the Alabasta Arc, it's practically canon that Tashigi will get way, way stronger. Boa hates the world government, and Tashigi is one of the few genuinely good people in it. Boa and Tashigi are likely going to be in close proximity this arc. Somehow, Boa will be impressed with her like whoa and become convinced that they are in a Romantic Two-Girl Friendship. BUT...Tashigi will have lost her glasses, and due to not being able to SEE Boa, not fall for her charms like certain others. This will not hinder Boa at all due to her complete inability to understand that not everyone ([Oh my gosh!]!) is in love with her.
Sanji returns from Kamabakka with the power to HIT WOMEN!Pretty self-explanatory.
Pell is an AlienIn movie 8, the sound played when he lands on the clock tower sounds like he's warping. Then a ray of light sucks him in all tractor-beam-like, and then he survives a giant explosion. By deforming himself into a liquid-like alien state (rain) and then recomposing. Think about it.
Devil Fruits are, in reality, Alien Fruits.They just cause these effects on people because the Bizarre Alien Biology inside them made it possible. To the aliens that brought the fruits to the planet, they don't have any bizarre effects. Or just a slight indigestion.
Indiana Jones is Robin's father.He got himself killed by the Marines while studying the Poneglyphs, pissed off a Yonkou or Shichibukai, or the Indy Ploy failed disastrously.
Zoro and Perona got poofed to Silent HillFreaky Mind Screw moments and emotional trauma for everyone!
The "D" in the Will of D refers to the EndlessD can stand for Death, Dreams, Destiny, Despair, Delerium, Destruction, and Desire. All of the Ds, to some extent, seem immune to the powers related to the Endless. They are unafraid of Death, they fight for their Dreams rather than succumb to them, other than Blackbeard they rarely leave things up to Destiny and would sooner fight for what they want, they rarely give up in Despair, they encompass rather than are affected by Delerium and Destruction, and (from what we've seen thus far) seem immune to Desire.
Luffy's straw hat is one of the Pieces of EightShanks gave it to him after placing a bet on the new era, in other words entrusting him with one of the legendary objects used by the New World Pirates as they gathered. If the pirates ever meet up together, it'll play a large role in their war against the World Government.
Spanner created the lollipops used by the 4Kids Sanji, as well as created the 4Kids timeline.In all honesty, this'd make crazy sense. Ten Year Bazooka malfunction sends Spanner to the Golden Age of Pirates (or an alternate timeline, ala the Paradox and assists Sanji in his leg training, giving him his special lollipops to enhance his abilities. It'd tie together both series oddly well. Not to mention, it'd give a valid reason for the other things 4Kids did, such as the super-soakers and the cut story arcs-when he came, tech became developed differently, and things happened in a different way.
Ace will be reincarnated as Zuko.Well, they do both have fire powers and are like rivals to the protagonists of their respective series.
Oda really can read english and is secretely a troper.He reads this page to find out what everyone seems to think will happen, just so that he can continually throw us off. Only plot points that he's had planned since the beginning stay in place.
Oda is deliberately trolling the fanbase.
"One Piece" is actually a spaceship."One Piece" is actually a spaceship and when the crew finds it they'll spend another entire series sailing through space and fighting evil Space Pirates.
One Piece is specifically designed so that every Wild Mass Guess about it sounds sane.I shall demonstrate: Zoro will come to the rescue on the back of an army of giant, rapping flamingoes. See?
One Piece is actually...A full collection of the One Piece manga, Gol D. Roger found out that his entire life and world was nothing but a manga and decided to hide the knowledge for someone worthy to find out the truth...from it he knew he was going to die and that his words before his execution would lead to the world becoming just as the book said...
Iva is a Time Lord and their Hair is their TARDIS.
Luffy will ask Chopper where babies come from.Poor, poor Chopper would be too young and inexperienced to be able to explain it to Luffy without getting really nervous and scared, seeing how he likely would only have second-hand knowledge. He'll break down and just shove the book with the relevant information under Luffy's nose while running away crying like a little baby.
Sanji will learn Death Wink from IvankovWhen he uses it though it takes a new form because of his eyebrow, SPIRAL DEATH WINK! His wink will be the wink that pierces the heavens and the distance between man and woman. OKAMA SANJI!
Smoker's scar is the result of a chest-waxing Gone Horribly Wrong.Just what it says.
Akainu is Clifford.It's not just a name thing, Akainu transforms (or once was, maybe in a past or future life) into a red dog. A big red dog.
Sanji will gain a new move durring his training, and it will be...Him shouting "I AM A MAN!" while
X Drake is Dio from Steel Ball Run.HE TURNS INTO A DINOSAUR. What more do you need?
The World Government is 4Kids EntertainmentWhen localizing the scripts of the Poneglyphs, they censored out all references to the Void Century because it was deemed too violent (or too raunchy). The only way to find out about the Void Century was through the original material. The scholars of Ohara were planning to do release an uncut, subbed version using the Poneglyphs, which would have infringed on their copyright (the main reason that the World Government hates pirates), so Four Kids had them killed.
Coby has a serious case of Osgood–Schlatter
Oda, his assistants, and the people who make the anime draw tons of One Piece Rule 34 for fun/to blow off steamLook, these guys are only human. And it's gotta be tempting for the creators, who are likely mostly very world-weary adults, to explore the seamier side life of characters from a children's manga/anime. And given the sensibilities they display in interviews and such, it's probably hottest, yet most utterly bizarre, insane yet strangely heartwarming porn ever. And it wouldn't end there; it's not unheard of for animation teams to make gag animatics (videos with storyboards/voices) with with really, really violent/sexualized material they'd never be able to put on air. In other words, somewhere out there is a virtual mountain of One Piece porn that we'll probably never get to see unless someone decides to be a jerk and risk the inevitable controversy by posting it online.
The sea bear wasn't stopped by hakiIt stopped because Luffy was standing inside an anti-sea bear circle.
One Piece takes place in the same universe as Stargate SG-1The Void Century in One Piece is actually the period of time where their world was under rule by the Goa'uld. The Ponyglyph contain Goa'uld writing and the ones about that weapon are for an alien device used for war/destruction. Since the Goa'uld were known for their experimentation, that's why the people in One Piece are so messed up. Their world was one of the few that imported animals as well as humans so the Goa'uld experimented on them too.
Mihawk and Doflamingo do comedy routines when they're not busy doing Shichibukai stuffMihawk's the Straight Man and Blue Oni, Doflamingo's the WiseGuy and Red Oni.
Post time-skip Blackbeard is a vegetarianTo make him further opposite from Luffy
The treasure One Piece is truly a ticket into another world.
The Straw Hats hang out with the villains behind the scenes.Examples: partying with Arlong, busting out dance moves with Don Krieg and Gecko Moria, having secret rendezvous with Crocodile and the Baroque Works agents, sharing slapstick with Doflamingo...
Regarding everything that's being done by the World Government....Palpatine's behind it all!
Eneru's favorite song is Savage Garden's "To The Moon And Back."After all, he goes to the moon and forms a whole empire there.
Arlong can be kept in check by threatening to make shark fin soup out of him.Exactly What It Says on the Tin.
Vander Decken IX's power is not that of a devil FruitNo the Mato Mato power doesnt come from a devil fruit it comes from a devil vegetable
One Piece doesn't existEveryone is lying about it being real
The entire series is being scripted along the way by an in-universe characterThe character in question is drafting the entire plot on a script-board, drawing actions as the need arises or simply to be a Jerkass, similar to what Bugs Bunny once did to Daffy Duck in a Looney Tunes cartoon and what Elmer Fudd did to Bugs himself as well. The question is, which character is responsible? There are possibly several good candidates for the post, but the best one: Gold Roger himself.
One Piece isa single gold coin. Gol D. Roger sqandered the rest and sent everyone on a wild goose chase
One Piece is Rouge's PantiesCan't believe no ones suggested this yet. This would lead to Sanji and Brook feeling a great respect for the Pirate King, and the rest calling him a pervert. Alternately its were hid his porn, after all highly doubtful Rouge would think to look there.
Sanji and Shanks are relatedPower of Coincidence being what it is in One Piece, having two characters, both from the same sea, with similar looks (Or is it just me?) and similar personality flip tendencies (Shanks is happy go lucky, but don't 'F' with his friends, Sanji can become calculating, manipulative and down right scary if you 'F' with his crew, plus both are good at Convenient Speeches of Awesome) plus Sanji's level of Badass Normal makes me think that they are related. Illegitimate son mebbe?
Someone is going to ask Oda about the time he met Moritaka Mashiro in a future SBSIn Chapter 130 of Bakuman。, some of Mashiro's classmates ask if he has met Oda, and he says he has. Considering some of the SBS questions and Oda's answers to them, it's possible that if someome asks this in SBS, he:

Pandaman is the father of Roger
One Piece's world is actually IscandarA planet that's mostly water, with a strip of land crossing it, dotted with islands. And it turns out iscandarium is actually Sea Stone.
Theories on the end of Blackbeard
The triangle-headed guy that keeps showing up in SBS will be made a Shichibukai after all.Cause hey, it's Oda.
Theory on Devil Fruits and FishmenThis idea won't leave my brain alone so I may as well post it. In chapter 641, one of the mermaid princes keeps asking Hody Jones "What are you?" and at the end of the chapter declares that he knows Hody's "true form." This would seem to imply that Hody has some sort of connection to humans he'd rather not acknowledge. Perhaps Hody was once a human who ate a devil fruit, specifically the Fish Fish fruit: White Shark model (or something similar). But how is he not affected by the sea if that's the case? We've seen that when Chopper gets dunked in water, he reverts to his half and half form rather than full human or full reindeer. If Hody's half and half form is his "fishman" form, it makes sense then that he wouldn't change underwater. And since that form has gills he doesn't have to worry about drowning. Another WMG for this series speculates that if a water logia fruit exists, its eater could be immune to the effects of the sea. If there are Fish type zoan fruits, perhaps the same is true for them. Alternatively, Fish type zoans may not be immune to the sea, but as long as they're in a form with gills they won't drown. Given what else has been done in this series due to determination and willpower alone, it might be possible for a Fish zoan to train him/herself to be able to move around when submerged despite the effects of the sea. As the flashbacks show, Hody's been a fishman for well over 10 years, so he's certainly had the time to train his abilities if he is a DF user. I could even take this a step further and say that a long long long time ago, there were no fishmen but there were a lot of Fish zoan fruits. The first fishmen were humans who ate those fruits, and never went back to their human forms. Perhaps they saw their human selves as weak or something. It wouldn't be the first time in fiction that humans gave up their humanity for such a reason. Somehow the half and half form got embedded into the population's genome, and their decedents (modern fishmen) have the strengths and benefits of the form without the downside of the fruit's curse. The trade-off is, they can't change forms any more. It would explain why fishmen and humans are compatible enough for blood transfusions with each other (that is, if cultural taboos are ignored). If these Fish zoan fruit didn't have any weakness to the sea (or just seemed dangerous enough in general), then the early World Government could have hunted down the fruit once the original power holders died and the fruit respawned. The WG then locked these fruit away and as time passed, people forgot that fishmen were ever human. Then Hody somehow got his hands on a Fish zoan as a boy and he discovered the truth. Maybe something happened in his early childhood that caused him to view his human self as weak and frail once he ate the fruit. Whatever the case, this knowledge influences Hody's rage toward humans and would even contribute to how in recent chapters Hody seems to have abandoned his idea of ruling Fishman island and is willing to let the ship Noah crash into the island and kill all its inhabitants including other fishmen.
Blackbeard is a rogue member of the Nara clan, or at least closely related.I mean, he can use shadows and is obviously an EXCELLENT tactician. Odds are that he could give Shikamaru a run for his money in a shogi match.
Doc Q is going to have a Let's Get Dangerous moment against ChopperI mean, Blackbeard says he doesn't let weaklings into his crew, but let in the sickly frail doctor. Add that to his speed defending Blackbeard against Whitebeard, and he's probably going to reveal himself as a Lightning Brusier.
Zoro converted to Judaism.From a conversation: "He's clearly been circumcised. That was the most rebellious thing he could come up with while training with Mihawk (who I'm convinced is a good Roman Catholic with the conquistador look and all)."
Nicolas D Wolfwood is the first or the last holder of the Will of DHe's a D and that means he has some sort of importance. Either the planet that he is on had OP take place either in its real far past or future. Also for this WMG to work Wolfwood totally knocked someone up before he died and carried on the Will of D, or humans had lived on the planet previously and died out because of the cataclysm that turned it into Arrakis. So he is either the last holder of the Will of D or the first holder. Also if the OP world is the far future, Vash is One Piece and he has been guiding Wolfwood's decedents for a long time from Raftel. He's their best bro. Because why not?
Boa Hancock will end up with AlvidaShe will get tired of Luffy not returning her feelings. Alvida is in a similar position, so yeah. And then the world will explode from the fanservice.
Hercules is gayHe has an Imagine Spot with a muscular Usopp clad only in a loin clothe, and when we cut to reality he's blushing..
There is some connection between the Spy and Crocodile.
Shanks will grow out his facial hairAnd become Redbeard
Roronoa Zoro is the long-lost older brother of Ryoga Hibiki from Ranma 1/2.He went out to get some milk one day, ended up in the One Piece world, and never noticed. This would explain everything about Zoro's character. EVERYTHING.
Oda was influenced by My Little Pony: Friendship Is MagicLets do an experiment. Look at Shirahoshi◊, now look at Fluttershy◊. Now look at Shirahoshi again, now look at Fluttershy again. What do you see?
Knuckles the Echidna was living on Angel IslandThe reason that he wasn't there during the Skypeia Arc is because Eggman stole the Master Emerald again and he was on the surface getting it back.
Zoro and Sanji will become an intimate coupleThink about it, the way these two fight clearly they secretly want each other. It's a psychological fact that the tension between these two is most likely sexual frustration.
Possible future Devil FruitsIdeas for Devil Fruits that haven't shown up in canon or filler, but that could possibly show up (or we wish they could):
One Piece is...
If One Piece was an tabletop RPG...
Luffy is trying to save Boa Hancock's life by not Marrying her
My headphones are a Pacifista
Pekoms is related to Smoker.
Sanji is going to die when the Strawhats have to go to Amazon Lily.
Eiichiro Oda actually writes each chapter in English first, then pulls out the english and inserts the Japanese when he submits it to Jump.It would explain why all of the dialogue in each speech/thought bubble seems to fit fairly well when translated into English. At least, in the scanlations. Considering that English is supposed to be the actual language of One Piece anyway, it would make sense for Oda-san to write it all in English first to see what it would look like.
The One Piece will be a piece of paper with the number 1 written on it.Luffy will be glad to have discovered it anyway. He'll put it on himself and declare that he's now Number One! I dreamt this last night so I might as well put it here on record.
Law cut out Davy Jones' heart.The 100 pirate hearts he gave to the World Government to become a Shichibukai were the 100 pirates Jones claimed from Jack Sparrow in Dead Man's Chest.
Caesar Clown and co. are taking orders from the Joker.
One Piece is a time machine
if One Piece treasure is anything but valuable, then Nami will hit Luffy like there is no tomorrow.
D means Danger.That's why almost all with D initial are dangerous, be he one of Marines(e.g. Garp), Pirates(Roger, Luffy) or Revolutionaries(Dragon). So far seemingly only Jaguar is exception(at least not dangerous), but he is, by no mean, a pushover either: a vice-admiral, after all.
Zoro's closed eye is a Sharingan
Akainu wrote Frigid Winds And Burning Hearts.All the Moral Dissonance is because Braveheart is his Author Avatar. Especially the victim blaming. When Applejack apologizes for how he was 'forced' to attack Sweet Apple Arces, he's imagining having Robin apologize for what he did to Ohara.
Haki is actually Spiral PowerI looked up the basis for Spiral Power...and I realized that both Haki and Spiral Power are very similar to eachother...though Spiral Power must be rare on this world.
Gol D. Roger was a pastafarianThe world of One Piece is in some aspects similar to ours, but it has a bigger proportion of seas vs land. The weather is crazy and in the Grand Line is just nonsensical, and the same can be said of the behavior of the sea. Technologically, they are the same or more advanced than us in some fields, they use electricity and electronic devices, and have instant communication based on electromagnetism just like us, they even have cyborgs armed with laser rays, but they rely on wind propelled ships to navigate (and, even weirder, their ships have the same commodities than our modern houses). It seems that one of the technological fields that they are way behind us is in the use of fossil fuels. My theory is that the world of One Piece is the future, the chaotic weather and weird natural phenomenons are the results of years of natural disasters due to global warming, and that's why they eventually stopped using fossil fuels (or they run out of it). Gol D. Roger was worried about the world eventually becoming uninhabitable for humans and, as a good pastafarian, knew the solutios: the world needed more pirates. So, he started the Big Age of Piracy to increase the number of pirates in the world and save it from destruction.
Nami can use Busoshoku HakiWhy else would she be able to injure Luffy (who is otherwise immune to blunt force) with her slaps and punches? I mean, come on! We got guys several times stronger than her not being able to bruise Luffy at all with their fists, yet Nami can do it? Just think about it. And don't say it's just for comedy!
The One Piece is a one-piece swimsuitBecause come on, it's too obvious.
Brook isn't exactly humanStrong roots. And how do you get strong roots? By not being human. Obviously.
Brook soul is green, Changeling magic is green......and if magic color is the same as soul color, it means that Brook is a Changeling!
Fake!Luffy ate the Gut-Gut fruit.And it turned him into a flubber man.
Brook's afro can deflate like Pinkie's hair"My friends don't like my music and they don't wanna be my friends anymore…"
Yorki was a ChangelingAnd he died because of a lack of happiness/love caused by his own disease, not the disease itself. Guys, that dude had an actual need for love and smiling and stuff like that.
Brook has a crush on Robin and Zoro
One Piece is just Brook being delusional.He survived the Rumbar Pirates' death and he made up the Florian Triangle and all of the Strawhats' adventures.
Brook got his afro because of something supernatural that happened to himHe had the straightest hair ever before that.
Brook lived again because……reincarnation is a common thing in One Piece's universe. Except, whoever was in charge forgot to erase Brook's memories of his previous life and sent him back to his previous body. His Devil Fruit just gave him soul powers that can be used only when you experience something so sad you lost your sanity.
The Seven Warlords of the Sea represent the Seven Deadly Sins.Something we've all heard a million times, but hear me out:
They represent the Seven Heavenly Virtues.
The One Piece contains...
Thousand Sunny's gonna transform into a giant robot
Lola will propose to Baby 5, and she will acceptIt will be be the grand co-dependant love story of the century.
Everybody wants UssopMaybe not everybody everybody, but way too many people. Let's review shall we:
Marco's Devil Fruit is a pineappleBut took a lethal fall down the stairs soon after.
Blackbeard is another son of Gold Roger.Mainly as a gag with Blackbeard's voice actor Akio Ohtsuka being the son of Roger's voice actor Chikao Ohtsuka. Also, because imagine how awesome it would be for Blackbeard to be Luffy's final rival for the Will of D.
Someone else has already found the dang treasure.Considering all the wacky side adventures and 30 episode arcs the Straw Hats and their enemies find themselves in I wouldn't be surprised if some ignorant schmuck has already found One Piece. Meaning when they get there they'll discover its empty and find a note saying "Captain (insert name here) claims One Piece and title of King of Pirates!" Resulting in the ending being a mad dash to find and beat the guy up.
Laboon is a female.They didn't check out Laboon's genital, did they?
Laboon is a four-dimensional space whale......that fed off the Rumbar Pirates' obsession with music.
The Strawhats will enter Sniper Island.It is a noted Running Gag that Usopp's lies turn out to be true. One of his lies (or at least deceits) was being Sogeking, the King of Snipers from Sniper Island. According to Usopp (or according to Sogeking, either way) Sniper Island is located "in your hearts". Trafalgar Law, captain of the Heart Pirates, is canonically from the North Blue. Therefore, it is the most likely geographic location for Sniper Island. Considering the North Blue is adjacent to the New World half of the Grand Line, where the Strawhats currently are, it seems very likely that if the Strawhats were to lose their course and temporarily leave the Grand Line and enter the North Blue they could end up on Sniper Island. Cue many a Face Fault from Usopp.
Luffy becomes the Pirate King, then Haruko captures him for world domination.In the final episode of FLCL, Haruko rides off on her vespa into space to find the pirate king or some intergalactic bullshit. Through the power of Oda, as soon as Luffy finds the One Piece on Raftel, we will see a yellow motorbike come out of nowhere, grab Luffy, and proclaim him as her lover as they take over the galaxy.
Brook is a mutated human.His hair has strong roots, he was very skinny when he was alive, his eyes were one of his mutant traits(and this is why he always wore his shades).
Calico Yorki is related to Nami.Because it's silly, OK?
Zoro is a deep-cover Ork.Albeit one that doesn't care much for dakka, but decides that having three choppy bitz instead of one or two is pretty well orky.
Brook comes from Equestria.Because he's a unicorn.
Spandam is a lot more badass than we were led to believe.Spandam's sword is an elephant. An elephant never forgets. Oda never forgets. Therefore, since Oda is too Bad Ass to work with a weakling, Spandam must be badass!
Shanks is the ancestor of Yujiro Hanma and Baki Hanma from Baki The GrapplerBoth have bright red hair and are insanely badass
Brook sometimes can see the readers.
Possible future fight...Franky versus Daz Bonez. Explanation? Man of steel who was a bounty hunter turned pirate versus man of steel who was a criminal turned pirate. Supa-Supa versus SUPER. It actually does make sense.
Brook will create a Stable Time Loop by travelling back in time and making Yorki contract the disease he had.
Brook's eyes didn't match the rest of his face.In fact, his eyes were downright creepy when they were seen together with the rest of his face.
Death is a female.And she's totally a Soul King fangirl.
Brook has Danny Phantom's powers.Not only he can separate his soul from his body, he can also turn his skeletal body...into a soul.
Brook is heterosexual and biromantic.
Cavendish is Calico Yorki reincarnated.
Brook's afro got replaced by a parasite that looks like his hair at some point during the year before his revival.
Brook is a disguised broom.
Ryuma was Zoro's Father or Grand-FatherNeither knew this, and never will, but Zoro basically burnt the corpse of his father/grand-father to ash.
Brook will be seduced by a crossdressing woman who's interested in the undead.
Gol D. Roger was really a dimension Traveling AtosmkBecause you know from one pirate king to another, it doesn't make sense for them to be different.
Pica of the Donquixote Pirates will be voiced by Ikue OhtaniI'm calling it now. In-story, he's a huge muscular man with a very high-pitched voice. Once the anime reaches the point where Pica finally speaks, what better way to do this than referring to another Pica (or rather, Pika) whose also voice by Ikue Ohtani? It helps that she's already in the cast voicing Chopper and the main cast has voiced secondary characters numerous times, so why not?
