One Piece/WMG/Confirmed

=== These are Wild Mass Guesses for the series One Piece which have been confirmed by the series or by Word of God. If a WMG on one of the open pages is confirmed, please move it here. ===

Please add new confirmed entries to the bottom of the page.

Luffy will faint from the invigorating hormone overdose after the war is over, allowing time for the other Straw Hats to have their stories fleshed out and for them to return to Sabaody.
By the time Luffy awakes, he'll be elated that his crew is safe and sound around him, and that the ship is ready to enter Fishman Island.
 * In the meantime, none of the crew are going to be sure whether or not he'll ever wake up, but because this is One Piece, they'll hold on to faith that he'll come back to them soon enough. The story at that point will be about the crew's efforts to take care of and protect him, with some deeper character studies on the way as a Breather Arc.
 * This came true.. Luffy's woken up on Amazon Lilly and is being taken back to the Saobody with Rayleigh, while the rest of the crew is making their way to meet up with him.
 * Not quite.

Kuma sacrificed himself for Luffy and his crew
. His disobedience on Sabaody in saving the Straw Hat crew led to a full reprogramming by Vegapunk which essentially "killed" him. He was fully aware of this, but willingly saved Luffy and his crew. This explains why he told Luffy before sending him flying with his DF powers that this would be the last time they saw each other, despite Luffy coming to Marineford. This also explains why.
 * Its seems you were right on the money, at least where the.
 * Almost.
 * Which would explain why

Buggy's plan will fail spectacularly and he'll nearly get himself killed for it, but be rescued by his crew at the last minute after they decide to turn back and go get him.
Because, come on, Buggy's set himself up for a painful fall, and in OP, friendship is always shown to be more important than power and dreams in the grand scheme of things. An event such as this could finally nail the manga's absolute main friggin' point into Buggy's thick, blue-haired skull.
 * Well, they didn't save him when he got over his head, but they have indeed rejoined him.

Akainu will have a plant/earth Devil Fruit
Akainu has a rose on his suit, has what appears to be a flower tattoo, and has a flower pattern on his shirt. The red in "Red Dog" could be because he specializes in roses.
 * Sort of confirmed. Akainu does have an earth-based ability. He's a  .

Crocodile's hook is hiding something
It looks awfully bulky. A good place to hide something...
 * Confirmed - it was revealed in his final fight with Luffy. It turned out to be...another hook. This one was smaller and was filled with venom; Croc only used it as a last resort.
 * Yep, it goes from hook to poison hook to hidden blade.
 * Ah, but what if all those are to hide the fact that he has something else hidden even further under? Like maybe the fact that he isn't missing a hand at all? Maybe there's an embarressing/important tattoo or something on his left hand, and the easiest way to keep it hidden was to make it look like it doesn't exist.
 * Yeah - the base is large enough to hold his hand, that hidden blade and other secret goodies. Also, a hand in there would have prevented the whole thing from snapping off when Luffy stomped on it unless it's fused to Crocodile's wrist bone or something. I say he's hiding the mark of the Tenryuubito in there, that would go well with his trust issues and some of the WMG here.
 * Dude is made of sand, and can turn his clothing, cigars and hook into sand as well. He could be holding pretty much anything in his anywhere, just in a sandy form.
 * Penis Blade?
 * He could have a slave tattoo 0_0

Mr. 3 will join Buggy's crew
Hey, they seem to get along, and I won't be surprise Buggy gives him an invitation.
 * He did.

Shiliewu Will Join Blackbeard
Currently, Blackbeard doesn't have a direct counterpart to Zoro. Shiliew seems to be a skilled swordsman and Blackbeard managed to get away from him completely unharmed. It's possible the two men may have came to a agreement.
 * And that's exactly what happened. Shiliew has joined the party! * 8-bit jingle*
 * Isn't it a great feeling when a WMG becomes true?
 * It's easy to become addicted to the high that produces and make billions of theories at once in hopes that at least one turns out to be accurate.

More Impel Down prisoners will join Blackbeard, and the remaining silver medalists join in the fight against Whitebeard
Luffy said he wanted 10 crewmates not counting himself. Blackbeard is Luffy's Evil Counterpart and has shown he's looking to increase his crew. Blackbeard and the rest of his crew were last seen heading down into ID, and as far as we know the only thing of interest down there would be the prisoners in Levels 5 and 6, such as Basco Shot. Also, said Level 6 contained prisoners who expressed a desire to kill WB.

Luffy's adrenaline will wear off, and he'll have a monster of an adrenaline crash at the WORST TIME POSSIBLE.

 * Confirmed, in a way:.

is screwed
The real purpose behind  is to be a more succinct version of the Really Dead Montage, to drive the point home that yes, he's dead, and he's not coming back.
 * Only problem is that NO ONE in One Piece, besides people in flashbacks and, have died. Oda specifically stated that he hates it when people die in stories just to get sympathy from the audience.
 * I think an exception can be made though if it's of world shattering, plot-shaking importance, rather than just killing characters to make the villain look more evil, which may be what Oda was referring to. Either way, it would be pretty silly if no named or significant character died in the upcoming battle, given how much it's been hyped up as a world shattering, plot-shaking event.
 * In chapter 573 it

is screwed.
Is This Troper the only one who thought "Ominous Foreshadowing" when Jinbe questioned what would happen if  suddenly kicked the bucket?
 * In the most recent chapter, Crocodile stated his intentions to take the old man out himself, and Jimbei intends on preventing this. It would be perfect dramatic irony that neither of them get what they want if  just dies from health problems.
 * This Troper doubts that Oda will break from his convention and actually kill one of his characters. Instead,  will be severely weakened and lose the bulk of his forces, thereby weakening the position of the Yonkous. This will leave room for the Rookies to muscle into his territory and still cause chaos without having   die.
 * The most recent chapter all but confirms that  about done.

The fate of an individual who consumes two devil fruits will be more important than it already is.
It so far exists to explain why nobody has two different powers, but the possibility exists that someone, like Kuma or Blackbeard because of their Game Breaker powers, will be killed by being force-fed a second devil fruit. Although with Blackbeard, his devil fruit may negate the second one without harming him anyway.
 * The reason it hasn't been explained is because Vegapunk, according to a member of CP 9 (Lucci I think) discovered it to be something to do with how it changes your body, presumably DNA or the like, and a second attempted change results in over-stressing the eater's body, killing them.
 * Seeing how now has the ability to also use another's DF powers....

Crocodile keeps helping because of Defeat Equals Friendship.

 * Basically, Luffy convinced him he was WRONG. But, he knows that Luffy won't buy it so he isn't even trying to argue it. He volunteered to help save, he makes sure to rescue Daz Bones, he stopped attacking Whitebeard on command, he saved Ace from the executioners, he stopped Mihawk from attacking Luffy, he rejected Doflamingos offer of alliance (which might have let him back into the Shichibukai) and he stopped Akainu from pursuing Luffy any farther. He's been so consistently helpful and loyal even when it's not in his best interest that something HAS to be going on with him. He'll still keep acting like a jerk because he kicked way too many dogs in the Alabasta Arc for anyone to buy anything like a heel face turn.
 * Consider this: Crocodile is like the Shiki to Luffy's Roger. Just like Shiki, Crocodile sees in Luffy his ultimate rival. NO ONE gets the privilege of doing in Luffy before he does, and he's willing to go to ANY length to preserve that.
 * But why save Mr 1 and Ace? Mr 1 is a strong fighter, but doesn't really carry that much weight when compared to the other extremely powerful marines and pirates in the battle. Crocodile has no real reason to save Ace, either.
 * He may be doing all this because he sees what he once was in Luffy and what sentimentality remains with him is driving him to stop Luffy turning out like he did. Maybe Luffy relit a spark of who he once was and it makes him ashamed, whether subconsciously or not.
 * Considering that he's planning to go to the New World, with Mr. 1 tagging along as his Dragon, it's quite likely.

There are more models of the Hito Hito Fruits.
Outside of humans, what other sentient species are there? Giants, Skypians and among others. Fishman and Merfolk however...
 * There may be Zoan Fruits for the One Piece universe's own animals.
 * Confirmed via the SBS via Volume 60. There is at least the normal one and a Mythical Zoan-type of the Daibatsu.

The straw hat once belonged to Rogers
It is not, however, One Piece. Rogers meets a young Shanks and gives him the hat, just like Shanks did with Luffy. The difference is that Shanks wouldn't let Luffy join his crew.
 * As good as confirmed in chapter 603, Roger is shown meeting Rayleigh wearing a strawhat

We're getting a time skip
Theories are that the 'message' Luffy left his crew is in his newly-gotten tattoo, visible in the newspaper picture. This tattoo supposedly says "SA 2 Y". Sabaody Archipelago, Two Years. This is why the rest of the crew suddenly change plans: their meeting is 2 years from now.
 * This would explain Oda saying this was Luffy's last adventure in as an 18-year-old. Or whichever age it was. Here's the picture if you're confused.
 * Spin off theory: Zoro won't get the message and will go straight to Sabaody Archipelago, and will proceed to wander around for two years until he finds the Going Merry.
 * That, or clueless Zoro will need Mihawk to explain the message, which conveniently lets Oda explain the message to the reader.
 * I thought that SA 2 Y meant Sabo Ace 2 Yujin (Japanese word for friend). Maybe it's a duel meaning.
 * The armband is just a Red Herring for us, and tribute to Ace for him. The true meaning is the ringing of the Ox Bell. Which, given Killer's explanation, seems more like a one year time skip.
 * There's the possibility that the Ox Bell is the Red Herring and the tattoo is the real hidden message
 * And ringing the Ox Bell sounds more like something Luffy would do out of a whim than getting a tattoo. Rayleigh said it himself, the message is in something Luffy would otherwise never do.
 * Unless the tattoo (which, whatever it says is very similar to ace's) is Luffy's way of memorializing his brother
 * All but confirmed, since everyone is preparing for staying a while on wherever they are.

Mihawk will train Zoro
Every other Straw Hat is at an island perfectly convenient to help them get stronger. So who better than the world's greatest swordsman to train him? I know its not likely, but hey its a WMG.

The character with an eye patch planned will be Zoro.
Look at the latest chapter title. His right eye is closed and has a great scar over it. It's possible he's just got the scar anyway and the eye escaped untouched, but it feels a bit weird closing that eye when he's just standing there.
 * That would be AWESOME
 * As of ch. 599, it looks like
 * Probably fell down the stairs.
 * Mihawk fell down the stairs carrying his sword, nicked Zoro in the process and then impaled himself at the bottom of the stairs. Zoro looks at him, then at the stairs, and decides he can brag that he lost his eye when he defeated the world's greatest swordsman. Then he empties his bar and leaves. That's why he was early to Sabaody - he started his journey before the others.
 * Actually,

Fishman Island is the next destination.
Bear with me here, folks, but it's a high possibility given that they can finally go underwater. I know it sounds crazy, but it could happen!
 * As of Chapter 607, they've finally arrived there.

The reason there's been no water-element (ice yes, water no) Logia user yet is because they wouldn't have the normal weakness of Devil Fruit users

 * ...uh, yeah. That's not really a WMG, since its more-or-less obvious. Less of a guess nor is it wild.
 * Uhm, Chapter 603 is out, so...wow, great timing on this WMG. Still, it could turn out Caribou has something like slime or, more in character for Caribou, blood... I mean, the filler Logia's were both semi-liquid and still had the standard weaknesses. A slime Logia would most likely completely solidify. But then, we're underwater now...next chapter should prove to be interesting.
 * Well, they would have one non-standard weakness: Crocodile would be able to neutralise their power by absoring their moisture. On the flipsode: They (in this case Caribou) would be able to neutralise Crocodile's sand defense and hurt him. So basically they both neutralise one-another abilities, which makes them pretty much natural enemies, like Luffy to Enel. Also, rooting for Crocodile Vs Caribou now. And then there's probably the fact the things get mixed in liquid easily - for example, if sea water got mixed in with his body, Caribou would probably need to take time to get the sea water out of his body in order to use his abilities. Also, Akoji could proabably one-shot him really quickly with his Ice powers, since Caribou is made of an unidentified liquid...
 * Caribou's power is more mud-based, as Franky reveals.

The 601st issue will be the start of a new voyage
The 600th issue being special was a Red Herring, the 601st issue start the voyage because it was 600 issues after Luffy's first journey started.
 * Well, all depends how quickly A. the Fakers and/or the Marines are taken down, and B. How fast Brook can get back.
 * Sorta confirmed. The chapter was titled "Romance Dawn of a New World," and when Luffy re-declared his ambition, though they didn't actually launch until the next chapter.

Things are only going to get worse for a while.

 * Isn't it inevitable? Absolute best-case scenario (unless it was All Just a Dream), with Oda's level of storytelling, he'll eventually have to deal with, which will be just as depressing as the actual event. And that's excluding that currently, he's up against some of, if not the, the most powerful people in the OP-verse, and Whitebeard is likely still to die. Worst case scenario... can you say "killing spree"?
 * Sort of confirmed; dies,  shows up,  dies, and now (chapter 577) . Can you say FUCKED?
 * Then there's the hell the World Nobles have promised for the Strawhats when they return, Merman Island losing Whitebeard's protection and falling victim to pirates and slave traders and Luffy's body still being strained and losing his years of life.

Sengoku's fruit is actually a Zoan type.
He has a Buddha form and a half-Buddha form.
 * Confirmed as of SBS Volume 60. Mythical type, too.

When Zoro returns, he'll pull a Mihawk and utterly wreck whole ships.
The Straw Hats that'd gathered so far will be in a jam, surrounded by enemy ships... until Zoro makes his dynamic entrance.
 * Well,.

Oda knows about the Luffyko April Fools joke and found it incredibly amusing.
Expect to see Luffy genderswapped for real some time coming up.
 * Confirmed via SBS, and the whole crew is with him.
 * That genderbent image of Robin is probably the funniest thing I have seen in a long time.

After the "Save Ace" arc there will be a Time Skip wherein the winner of the war will control the world and Luffy hides with the survivors
Luffy's Nakama have scattered around the world and seems to be finding niches of their own to fill (Franky finding Vegapunk's lab, Robin being saved by the Revolutionary Army, etc.) they would all take levels in badass to be competent enough whenever Luffy finds them again after the time skip.
 * Also, since Oda's favorite manga of all time is Dragon Ball and there were a few time skips there, it would seem that the Time Skip is inevitable.
 * Also the Marines would probably win. For plot's sake.
 * Correct as far as the time skip and taking levels in badass goes.

The straw hats separation is a Gambit Roulette by Kuma to make the straw hats stronger for some reason.

 * Luffy landed on an island with the one person (Hancock) who would sympathetic to his cause, have knowledge of Haki, and in an easy position to help him.
 * Clima-tact-using Nami landed on an island dedicated to the study of weather.
 * Cyborg Franky
 * Sanji is on an island that perverts his greatest love. He'll come out stronger by being able to hit women, as stated above.
 * Alternatively, all that running will have increased Sanji's leg strength.
 * Chopper is on an island with birds. Many paralells have been drawn between Chopper and Rudolph, but one key difference? Chopper can't fly.
 * Robin, due to her revolutionary status, is probably the most dangerous member of the Straw Hats bar Luffy and Zoro.
 * Zoro was sent to that island not to learn anything, but to recover. In his current state, any attempt to train him would likely kill him, so Kuma sent him to a mostly deserted island where no one can hurt him while he recovers. He sent Perona there too, because he didn't know what else to do with her.
 * He sent Perona there cause that what she asked for. If this theory is true, he must have plans for Perona, like knowing she might aid Zoro, or another Gambit, like them forming an Enemy Mine.
 * Maybe Zoro trains by subjecting himself to her negative hollows and by conquering ultimate despair becomes a stronger swordsman.
 * Alternatively, Zoro may discover a ridiculously powerful sword on that island.
 * Yet another theory: The island is Mihawk's birthplace. He sails around in a coffin surrounded by candles and generally gives a Dracula vibe, down to his name. Him coming from a spooky, gloomy island would fit with his theme.
 * Zoro can't do any physical training (not that he needs it), but his attitude, and general cockiness will probably take a hit from hanging around with all of the ghosts. In other words, he's going to be doing character training.
 * Also, Usopp is training with a great (and possibly cyborg) warrior.
 * If the Longarm tribe are anything like Scratchman Apoo, music plays a big part in their lives. While Apoo's explosive power is most likely from his devil fruit, the music connection may be beneficial to Brook.
 * And in relation to this...
 * If the Longarm tribe are anything like Scratchman Apoo, music plays a big part in their lives. While Apoo's explosive power is most likely from his devil fruit, the music connection may be beneficial to Brook.
 * And in relation to this...

All their power-ups will go something like this...

 * Luffy: Boa will help him master Haki and it will allow him to hit Logia-users (such as how Rayleigh was able to stop kizaru's attacks).
 * Zoro: Related to the 'spooky castle is Mihawks home' guess, Zoro will meet the person who trained Mihawk/find out how Mihawk got so strong, then after healing, will train.
 * Nami: She will get the weather scientist to help her power up her clima-tact with more advanced weather abilities.
 * Usopp: On the dangerous island, with the warrior, he will become stealthier and faster, along with being more durable.
 * Chopper: The whole 'Chopper will learn to fly' guess seems to be the most effective for the bird island he is on, that or he will become more independent and brave.
 * Robin: She will get smarter then she already is and become a great tactician or.. something(sorry, not much I could think of, besides being with a group of clever revolutionaries).
 * Sanji: The other guesses (able to hit women, running will make his legs stronger) work.
 * Franky: He will steal some of Vegapunks blueprints and equipment, hide somewhere, and power himself up.
 * Basically confirmed.
 * Brook: He will learn many different musical attacks (similar to his lullaby thing from the Flying Fish Riders fight).
 * Pretty much all confirmed.
 * Basically confirmed.
 * Brook: He will learn many different musical attacks (similar to his lullaby thing from the Flying Fish Riders fight).
 * Pretty much all confirmed.

Kuma and Garp are secretly allied with Dragon

 * Garp seems to still be in contact with Dragon and doesn't seem to be too terribly distressed about Luffy's actions in Impel Down. Since he's a higher up in the World Government, he'd make the perfect inside man to help Dragon take care of the Gorousei and staging an ultimate coup to bring down the World Government.
 * It also seems rather convenient that Kuma is such a trusted ally of the World Government, yet has constantly failed to eliminate the Straw Hats whenever ordered. It's also a little too convenient that he The rest of the Straw Hats are also in places that seem either valuable resources or potential Power-Up stations.
 * Also, both of them are in on a great big, centuries long conspiracy that seeks to...do something awesome but horrible and dangerous that could get some crap blown up by accident.
 * Never would of thought of any of this, but it makes so much sense it's scary.
 * Third panel on this page. Now doesn't he look familiar?
 * That's
 * *Ahem* He means third panel when reading right to left. is only in the third panel if you're reading left to right.
 * *Ahem* He means third panel when reading right to left. is only in the third panel if you're reading left to right.
 * *Ahem* He means third panel when reading right to left. is only in the third panel if you're reading left to right.

The Impel Down Arc will culminate in a major case of Nice Job Breaking It, Hero
Specifically, Luffy will accidentally cause Whitebeard's death, throwing all the islands he claimed into chaos and ruin while successfully rescuing Ace.
 * And then, the stress from discovering Whitebeard's death will throw Ace over the edge, making him lose the will to live, and die in Luffy's arms. Do the Trauma Conga Line, my candies!
 * Sorta confirmed...

Whitebeard is eventually going to be a Supporting Leader for Luffy
Granted, Luffy and his allies would be unable to rescue Ace without their help, but all this set-up seems be to echoing previous battles such as Wyper and the Shandorians versus Enel. It's very likely that all these incredibly overpowered pirates are going to end up Worfed in Luffy's favor.
 * Well, once could say they did in a fashion in helping Luffy to the execution platform.
 * Well, once could say they did in a fashion in helping Luffy to the execution platform.

The next time we see Usopp, he'll have become vastly more powerful.
Consider Oda's perspective on this: Why send the weakest protagonist off alone, with only an obvious Badass Grandpa/Old Master type for company, and then make him absurdly fat? To surprise the reader when the character comes back absurdly muscled and ass-whooping of course! Though, knowing Oda, he could well keep (some of?) the fat but still be ludicrously strong.
 * That could ruin Usopp's Badass Normal trait, considering Oda said he's suppouse to be as close to a normal human.
 * Nah, Sogeking didn't ruin it either. Why should this one?
 * Sogeking was just Usopp using different gadgets and a slightly more confident personality. Giving him an actual power like super strength would indeed wreck his Badass Normal status, and go against Word of God.
 * So then, does the ability to take a four ton baseball bat to count as a normal human trait? Admittedly, in this story, it is hard to tell.
 * Who says we want to give him super strength or anything stupid like that? No matter how you look at it, Sogeking was still a significant upgrade, as far as Badass Normals go. Give him another one like that, and he'll be a real powerhouse.
 * Here's an idea. Who else have we seen whos fat, but also increadibly fast and stealthy in One Piece? Lucky Roux. Somehow Ussop is going to increase his speed and stealth by training while bieng fat. And for a Sniper, that's a great upgrade.

Humans, fishmen, and mermaids are one species and can all interbreed
The possibility is touched on when it's shown that humans and mermaids can have children. Presumably, mermaids and fishmen can as well, if Caimie's attraction to Hatchi is any indication. Humans and fishmen seems the next logical step.
 * We know Fishmen and giants can interbreed, as we see with Big Pan of the Foxy Pirates; the half breeds are called wotans. Humans and Fishmen are the next logical step. Maybe a halfbreed will join the crew at Fishman island.
 * We also know that humans can interbreed with mermaids, having seen that is the 3/4 human granddaughter of mermaid.
 * And Fishman/Merman mixed marriages are quite common on Fishman Island, and they can have children together.
 * The Blue Databook confirms that Sapi, a fisherman from Loguetown is a human-fishman hybrid, so all three species can indeed interbreed.

In the New World just as in the first half of the grand line each had it's own climate, the islands here will have different physics and related Raftel and Will of D WMG
As above, each island and it's surrounding ocean will have slightly different but progressively weirder physics and native wildlife. Stuff like icebergs melting upwards creating pillars of water going into the sky, the ocean curling over itself, volcanoes erupting continuously, bizarre skies, low hanging moons and insane gravity. This will get progressively weirder and weirder til you reach Raftel which has no set laws of physics. If anyone here has read Roger Zelazny's Nine Princes of Amber series, I'm thinking something like approaching the Courts of Chaos here. The Will of the D is needed to approach Raftel as otherwise it's formless chaos with the One Piece sitting in the centre of it completely untouchable, but someone with the D can shape Raftel to reflect themselves by force of will. When Roger went to Raftel it looks nice like in the flashbacks because that's what Roger wanted it to be. When Luffy and probably  fight there it's going to considerably less pleasant. Basically Raftel is literally a place created by dreams and only the most determined are able to reach there. The series entire ongoing theme made manifest.
 * Almost certainly confirmed, at least partially--with the weird gravitational anomaly pulling Capone's ship out of the ocean, Urouge coming across an island with perpetual lightning where umbrellas are of utmost importance, and Scratchman Apoo discovering they're sailing in midair, we can safely say that the New World has Wackyland physics.

Sabo is going to die
Lessee...character-building flashback? Check. Intriguing and well-designed character? Check. Probability of dangerous pirates willing to kill children? Double check!
 * Alternatively, he's going to get kidnapped and enslaved by the World Nobles.
 * Or, he betrays Ace and Luffy.
 * Before Ace died, he mentioned Sabo as one of his good friends.
 * More proof:
 * Confirmed, his ship was blown up.

Hodi Jones was the main cause of Otohime's death
All right, this one's pretty easy to figue out, but seems funny some random pirate just happened to die when he was all alone with Jones, a guy who hates Otohime enough to comitt fumi-e on her in the present, isn't it? And how his little speech is lees "Oh my God, she's dead!" to "Oh my God, a human killed her!" in a attempt to get people away from her ideals and the intergration thing. Either he forced the guy to kill her, and then cut the loose end, or he did it, then killed some random guy that just happened to be there. And Hodi has shown have anti human tendancies before her death,there were several panels with him and his mates cheering on Tiger when they heard of his attacks and hero worshipping Arlong. All this besides the fact that he was, when Otohime was clearly shot from the front. And before you suggest that. Besides my previous arguments, nothing leading up to or during the 'compulsory crewmate troubled past flashback' had any slightest suggestion or foreshadowing of. If, now that the flashback has finished, it was revealed that, that would be a complete and utter Ass Pull, and frankly a low point in Oda's otherwise excellent storytelling.
 * I have to dispute this one, considering that Otohime's death fell right in with . Plus, Hodi's anti-human stance didn't really crop up till after Otohime's death.
 * From a different Troper to the original poster, while Hodi being respnsible for Otohime's death may be the obvious answer, i highly doubt was in any way responsible for her death, as.
 * From the troper who supports being the one behind Otohime's death: one doesn't have to be interested in the local politics to assassinate an important political figure. Such an assassination can happen purely for one's own personal motives, which may have nothing to do with politics..
 * While its true whoever assassinated Otohime didnt have to have done it for political reasons, they still would have had to have some motive. however has not shown any possible reason for wanting to kill Otohime.
 * But Hodi's not shown to have any real reason to actually kill Otohime, whether he agreed with her campaign or not. Plus, nothing in the current-day events or in the flashbacks even remotely suggests that he or any of his crewmates had a hand in her death, either. On the other hand, it would be just like to create a very convenient distraction (i.e. the burning of the signatures followed by Otohime's shooting) to pull away all attention so that . And it wouldn't be the first time such an underhanded tactic has been used in the series, either...Crocodile created the civil war in Alabasta to cover up his own search for the Pluton weapon; Spandam created the whole fiasco with Robin, and then tried to take advantage of the Straw Hats' Big Damn Heroes at Enies Lobby, in order to score points with the World Government; and Blackbeard used the Whitebeard War to his own advantage.
 * Actually, there is one. In Chapter 625, when the Tenryubito comes to Fishman Island, Jones makes a comment about him and his ilk being "the worst trash in the world". Given their slavery of Fishman, it's not hard to say Jones hates them among all other humans, and so when Otohime spared him, in his mind, it's not hard to say he thought of her as a Quisling type, and due to his extremly rascist views, also probably wasn't a fan of her wanting to bring the Fishmen in human lands.

A variation of Tactics 15 will show up later in the series and important in a big fight.
Knowing Oda, it was intentionally never shown, so later on a full-sized version where all the Straw Hats participate will be revealed to be highly powerful and take down some big opponent.
 * Confirmed: Franky's new Giant Mecha "General Franky" is based on "Docking," as noted by Chopper and Usopp.

Luffy has learned how to vulcanize himself
When he used Gear 3rd against the Kraken, his hand turned black. While the Haki he imbued the attack with may have something to do with it, other people have used Haki without changing colour. Vulcanizing rubber makes it harder and tougher, so it would be an apt power-up for him.
 * The translators that do the first version of the weekly chapters were noted to say they messed up on that. It was supposed to be read Vulcanization instead of hardening.
 * Ah, but that just goes right around into Fridge Briliance - after all this IS Luffy we're talking about. Do you honestly think he'd use the term 'Vulcanizing'? Alternativly, it could be a way of Luffy's Body showing when he's using Haki... which, while it helps the reader with a visual clue (for those who miss the SHOUTING AT TOP OF LUNGS), also probably clues in Haki-savvy opponents of what he's doing.
 * Confirmed: He has used the ability subsequently.

Jones will...
, pop some steroids in his mouth, and.
 * Might as well toss this in Confirmed, as what happened was close enough.
 * Might as well toss this in Confirmed, as what happened was close enough.

Scratchman Apoo is a member of the Longarm tribe.
Not only does he have unusually long arms, but they also seem to have an extra joint, exactly like the other longarms. Given that Brook fought the longarms after he was sent away by Kuma, this may hint at a future confrontation between the two music-themed pirates.
 * Given he also has the same type of old Chinese dress, I'd say this is a given.
 * He has two elbows, he's of the Longarm tribe. In fact, he was the first member of the Longarm tribe to be introduced.
 * This was stated the first time we saw him, it is hardly a theory.

The straw hats separation is a Gambit Roulette by Kuma to make the straw hats stronger for some reason.

 * Luffy landed on an island with the one person (Hancock) who would sympathetic to his cause, have knowledge of Haki, and in an easy position to help him.
 * Clima-tact-using Nami landed on an island dedicated to the study of weather.
 * Cyborg Franky
 * Sanji is on an island that perverts his greatest love. He'll come out stronger by being able to hit women, as stated above.
 * Alternatively, all that running will have increased Sanji's leg strength.
 * Chopper is on an island with birds. Many paralells have been drawn between Chopper and Rudolph, but one key difference? Chopper can't fly.
 * Robin, due to her revolutionary status, is probably the most dangerous member of the Straw Hats bar Luffy and Zoro.
 * Zoro was sent to that island not to learn anything, but to recover. In his current state, any attempt to train him would likely kill him, so Kuma sent him to a mostly deserted island where no one can hurt him while he recovers. He sent Perona there too, because he didn't know what else to do with her.
 * He sent Perona there cause that what she asked for. If this theory is true, he must have plans for Perona, like knowing she might aid Zoro, or another Gambit, like them forming an Enemy Mine.
 * Maybe Zoro trains by subjecting himself to her negative hollows and by conquering ultimate despair becomes a stronger swordsman.
 * Alternatively, Zoro may discover a ridiculously powerful sword on that island.
 * Yet another theory: The island is Mihawk's birthplace. He sails around in a coffin surrounded by candles and generally gives a Dracula vibe, down to his name. Him coming from a spooky, gloomy island would fit with his theme.
 * Zoro can't do any physical training (not that he needs it), but his attitude, and general cockiness will probably take a hit from hanging around with all of the ghosts. In other words, he's going to be doing character training.
 * Also, Usopp is training with a great (and possibly cyborg) warrior.
 * If the Longarm tribe are anything like Scratchman Apoo, music plays a big part in their lives. While Apoo's explosive power is most likely from his devil fruit, the music connection may be beneficial to Brook.
 * And in relation to this...
 * The heart of this is true, though some of the more specific guesses are false.

Dadan is another Chekhov's Gunman
It seems rather suspicious that we have yet to see even a silhouette of Ace and later Luffy's trainer/guardian and don't even know his/her gender, age, or rank. He/she might even be an already-established character with which Luffy and Ace have yet to interact.
 * Dadan is The Pandman? ... Actually, that would probably be both hilarious and awesome.
 * Confirmed. She was the one that took care of Ace and Luffy when Garp was away.

Blackbeard will become one of the Four Emperors.

 * While he DID  he did it when he was in a weakened state, and needed his entire crew to help him. Whitebeard was pwning Blackbeard's [bottom] until he called for backup. If it had been a fair fight Whitebeard would have whupped him in seconds. So Blackbeard doesn't immediately become Emperor level because Whitebeard was basically at [OneHitPointWonder: 1HP] by that point.
 * Following that Video Game-related wording, one could say.
 * Seems likely; the Gorusei even point out that Blackbeard has a major advantage over the competition, having two Devil Fruit powers, a crew made up of some of the worst criminals ever, and an intimate knowledge of Whitebeard's former territories. His only real competition for the position is Marco and the remains of Whitebeard's crew, and

Jinbe's reason for wanting to meet with Luffy is one of three reasons
Either he wants to join Luffy's crew (either because he respects him that much or he wants to look after Luffy for Ace's sake), he admits he wants to join but there is a reason he can't, or he wants to tell Luffy how to defeat Hodi, which is why he told Luffy not to fight him. Of course, if you can think of other possible reasons, please be my guest.
 * I'm inclined to agree with you, re Jimbei joining Luffy. Actually, I was going to put it in a separate WMG that Jimbei will in fact join Luffy, for these reasons: (1) he promised Ace he'd protect Luffy; (2) he and Luffy have both lost someone important ; (3) he presumably has a tragic background in that he was (very likely) one of the slaves freed by Fisher Tiger; (4) he promised Luffy he'd wait for him at Fishman Island, and is currently waiting still in the Sea Forest area; (5) it would be both very cool and very useful for the Straw Hats to have a Fishman member. If there are any more reasons that I've forgotten, I'll remember and add them as necessary, but yes, Jimbei really should join the crew and would make a fine addition (perhaps as their quartermaster/tactician or helmsman).
 * Position is a non-issue, the Straw-Hats have an archaeologist for Bink's sake.
 * Yeah, an archaeologist who can translate the Poneglyphs for them and thus guide them accordingly in their journey, plus one who's had extensive experience in assassination...
 * Partly confirmed, namely the bolded part of the original WMG

Akainu is the current fleet admiral.
Sengoku's recommendation that should become the next fleet admiral was just a red herring. It's awfully suspicious that after the time skip, the new fleet admiral would be mentioned but not named. Akainu also has the credit for the kill on Ace and did a substantial amount of work towards Whitebeard's death.
 * Makes sense. He's probably the most fanatically loyal to the concept of Absolute Justice in the world, and has no mercy, when the Five Elders think is needed in the Rampaging Era. And since it's likely that the WG will fall apart by the end of the series, the worst choice because his soliders might not be so willing to be so cruel as he at the end, causing a rift of Justice.
 * If that is the case, then Akainu would be in the perfect position to become the entire series' Big Bad (assuming Blackbeard won't already have that slot by Oda's reckoning). Or, at the very least, Akainu will perhaps be The Dragon to whoever Sengoku's superiors are, whether the Five Elders or whoever else sits at the helm (assuming isn't already fulfilling the role of The Dragon for that entity).
 * Confirmed, he faced Aokiji in a duel and won. Aokiji left the marines.

After the Whitebeard War, Akainu will become the new Fleet Admiral. Smoker will be promoted to Vice Admiral.
"# ) Garp, Helmeppo, and Coby get imprisoned for insubordination and their relationships with Luffy (and in Garp's case, Dragon and Ace as well). If any of them are slated for execution (probably Coby), this could also give Luffy a chance to redeem himself for failing to save Ace.
 * Akainu just earned himself a truly infamous position, and proved himself a great planner in addition to being a General Ripper psycho. He could be the first Admiral in line for a promotion if anything happens to Sengoku. Meanwhile, Smoker will get a promotion to Vice Admiral to become a Generation Xerox of Garp.
 * He still has to go through the rank of Rear Admiral, though.
 * I can see this happening. Sengoku will confront the five old guys about their cover-up of the Level 6 incident, and they'll in turn have him removed from his position. Akainu rises to Fleet Admiral for reasons above. And with Akainu in charge, a lot of things can go wrong:
 * 1) ) Sengoku is driven to exile. He blames the Strawhats and hunts them down personally.
 * 2) ) Luffy now has a real reason to fight the marines: the guy who killed Ace is in charge."



Aokiji and Akainu fought on Punk Hazard Island
Punk Hazard was an abandoned marine outpost where Aokiji and Akainu chose as the location of their big battle. The fight was so intense that it turned the island into a Hailfire Peaks-themed island.
 * Problem with that. Smoker and/or Tashigi state the island got closed off due to a disaster that happened four years ago. We've only had a two year time-skip.
 * They could have chosen it precisely because the disaster made it deserted and forbidden to step on. Also, whoever was on that distress call to the Straw Hats alternated between complaints of being hot and cold, supporting that the Admirals's battle happened there and had lasting effects.
 * Confirmed! As of chapter 658, We're told that Akainu and Aokiji did fight there two years ago. The result of which changed the weather of the island.
 * As for the accident four years ago, it's revealed that the place was a wasteland before the battle due to one of Vegapunk's experiments.

After the Time Skip Trafalgar Law became a Shichibukai.
Tying in with the above WMG. In chapter 656 the guy cut in half(who is probably a samurai) were asking Luffy and co. if they are the ally of 'that Shichibukai',and not in a friendly tone. This implies that it was 'that Shichibukai' who stuck the lower half of his body to the dragons neck,and we all know whose power is that.

Had he already entered the new world, where the marines have little power, he would be heading for raftel and would be in no position to accept the role of shichibukai. It is my beleif that he has taken a leaf out of Blackbeard's book, rather spending the last two years hanging around the grand line making an even bigger name for himself as so to be offered the position of shichibukai to further his own goals. Which leads to my next theory that...
 * If Law is the person responsible for the samurai's dismemberment as i suggested in the above WMG, and so is a shichibukai, it would support my argument that he has waited two years to enter the New World.
 * Confirmed. At least the part about Law becoming a Shichibukai
 * The second part is now confirmed. The samurai head says, while everyone is running away, that it was Law who cut him up.

Buggy will become a Warlord of the Sea.
C'mon-given the loyalty and everything he's been getting, it's not a far stretch.
 * From this page, it seems to be very likely. And it will be hilarious.
 * Confirmed. According to an official museum exhibit, with bounties obtained from Eiichiro Oda himself, Buggy's bounty has been canceled with no other indicators, meaning he has been inducted into the Seven Warlords.

Trafalgar Law created the centaurs, satyrs, and harpies.
We know via the marked Den Den Mushi that the harpy and the centaurs are connected. As of 660, it's pretty safe to say that if Law knows about the children, he knows about the satyrs. If the satyrs are connected to the centaurs and harpy, then Law is connected to all of them. We know that Law has the ability to chop people up and put them back together with others' bodies. Since the mythological humanoids we've seen thus far are pretty much all-human in some parts and all-animal in others, they being the product of Law's Lego Genetics doesn't seem so far-fetched. They are probably the new forms of his old crewmates. With this, there are two additional theories if this one holds true: Doesn't explain what that living gas/liquid boss thing that moves and can talk is. Though I wouldn't be surprised if Law has some connection with it as well.
 * Jean Bart is not only a centaur, he is the centaur boss. Jean Bart is quite the large guy. So is the centaur boss. It hasn't yet been confirmed that the boss is indeed a centaur, but if it is one and it is Jean Bart, that would add a lot of credence to the main theory.
 * The 100 hearts Law sent to the World Government to become a Shichibukai are the byproducts of the centaur/satyr/harpy/etc. creation. If each creature is the literal mashup of a human and an animal, then there would have been two bodies to work with. Now, there is only one body, which only needs one heart (same with the other organs). Assuming there are 100 of these creations of Law, he probably thought, "Hmm, I have 100 spare hearts from turning my pirate crew into mythological beings. Why don't I send them to the government to become a Shichibukai, which would protect myself and my crew from persecution?"

Oda is toying with us, and will bring the timeskip coverstory Up to Eleven for a big reveal
The last couple of chapter's covers have covered the Impel Down arc. Meaning that at any moment we are likely to get a reveal of what happened to Mr 2 Bon Kurei and Magellan. So Oda spends 3 chapters covering Hannyabal, Minochihuahua, and Sadi-chan with Saldeath. Surely the next chapter must cover at least one of the aforementioned two. Cue Chapter 664, and Oda has a colourspread instead of a cover. I think he's postponing the reveal as long as possible because the information will be important and will have a lot of impact.

My theory is that;
 * Mr 2 Bon Kurei is alive, and is possibly running New Kama Land for any new incoming prisoners, becoming the new equivalent of Ivankov.
 * Confirmed! Bon Kurei is alive and living in Level 5.5.
 * Magellan is out hunting Level 6 escapees, and may or may not have gained the rank of Admiral.
 * My assumption that he is an Admiral is based on the fact that he is likely that powerful, and that there are two unrevealed Admirals (assuming Kizaru hasn't resigned). The reason that he isn't at the prison anymore (obvious since Hannyabal is Warden) is either because he died of his injuries or because he is out there.
 * Jossed, Magellan has been demoted to Vice-Warden.
 * And now, One Piece is on break for a week. Dammit Oda, you Magnificent Bastard.
 * Nah, its just Golden Week.
 * Oda is the biggest f**king Troll in the buisness, it turns out Magellan is in fact.
