THEORIES & OPINIONS

Hello guys! There is something that came to my mind when I thought about Jewelry Bonney and her connection to the WG. Something that I couldn’t just keep for myself. I am excited what you guys think about it. So here I go…

So first of all, I know all the theories out there concerning her possible connection to the WG, more specifically being the one that keeps the Gorosei alive. I am not gonna argue against the idea in general, but there is one part that bothers me ever since I first read it. Most people think that Bonney was able to escape Akainu/ the WG because she and her powers are so important to the Gorosei. Therefore, they had to keep her alive and she somehow managed to get away. But for me, this really seems like a contradiction. If Bonney really was that important, how could they let her get away? Wouldn’t they do everything to keep her locked up somewhere deep inside Maryjois, especially when they already made that mistake and let her escape once before?

I mean, we have already seen how good the WG is when it comes to keeping certain people as prisoners. The Whitebeards + Luffy couldn’t rescue Ace. Even the most dangerous pirates couldn’t escape Impel Down for 20 Years. Yet, Bonney – who isn’t even close to the power level of an Ace – could escape them? Without any help? I can’t really believe that.

As I already said, I don’t doubt that she actually is the one who keeps the Gorosei alive. Yet, I doubt Bonney would have been able to escape once again if she got caught by the government. So here is what I think that happend: Akainu never captured Bonney!

Remember, in chapter 595 we only see Akainu talking to Bonney. But we never actually saw him take her away.

Akainu is not the type of guy that lets prisoners escape easily. So I think what happened is that Akainu actually freed Bonney and told her to get away and stay incognito (that’s why we’ve only seen her covering her face afterwards). Maybe he killed all of the remaning crewmates and maybe even some of the marines who witnessed the conversation between Bonney and him. This would totally fit his ‘absolute justice’.

The big question that should come to your mind now is: why would Akainu let someone with that power, someone that is so important to the Gorosei, run away?

My answer: Akainu is actually planning a coup d’état and wants (the marines) to take control over the Government.

As we can see in chapter 793, Akainu holds a grudge against the Gorosei. He disagrees with their way of doing things and obviously hates the fact the he has to take orders from them.

But Akainu has been shown to be loyal to the Government so far, some of you might say.

Yes, that’s true. I am not saying he wants to destroy the Government or something. He just wants to gain the power over it, which – at the moment – belongs to the Gorosei. Plus, he had to be loyal to become the fleet admiral in the first place.

I also think that this kind of move would totally fit his character. He has shown to be a very strict man who would rather surpress his enemies with force than negotiating or even compromise with them. So a lot the government respectively the Gorosei does (for example the Shichibukai system, spreading false information, etc.) does not really fit to his way of thinking. A coup d’état would make perfect sense for him.

But Akainu ain’t stupid. Actually fighting the Gorosei would make him an enemy of the Goverment and therefore he would never be able to take controle over it. So when Blackbeard called to offer the deal to him, Akainu came up with the idea to free Bonney. This way, the Gorosei will start to get older again and since most of them are already pretty old, they will sooner or later die. And this is the moment Akainu and the marines make their move and take the power over the World Government.

In short:
Akainu wants to take over the control of the Government, because he disagrees with the Gorosei’s way of doing things. But since he can’t risk to openly fight them, he uses Bonney ,who’s Power keeps the Gorosei alive. When Blackbeard captured her, Akainu let Bonney escape so that the Gorosei coldn’t make use of her power and therefore would sooner or later die of age. This way, Akainu could take over the Government without risking to look like a traitor or enemy.

Please tell me whether you think this is possible or not! Thanks for reading.

Time for another theory based on extrapolating predictions from references Oda makes to other works. But I have something a little different for you this time. The subject of today’s theory is J.R.R Tolkien

Yep, Tolkien. Of course the author of one of the most beloved fantasy series of all time. But where are these references in One Piece?

I suppose i’ll start with the trees since I mentioned them first in the title. We’re all familiar with One Piece’s Adam and Eve, but did you know that Tolkien’s universe also features two important trees? More specifically, the Two Trees of Valinor. The Two Trees of Valinor were sources of light, one representing the sun and the other the moon. Now Eve’s affiliation with sunlight is entirely obvious, and i’m sure people who have been reading my series for a long time are familiar with my assertion that Adam is on the moon. Furthermore, the Trees of Valinor were created by Yavanna, referred to as the “giver of fruits”. This further links Adam and Eve to the origins of Devil Fruits

But the title mentions the trees dying, and i’m sure you’re wondering where i’m going with that. So moving on. The Two Trees of Valinor were eventually destroyed by Ungoliant. Ungoliant was the first spider, and was said to consume light and excrete darkness. Surely this sounds familiar to all of you –

That’s right, Blackbeard. I believe that at some point Blackbeard will be responsible for the destruction of Adam and Eve, perhaps as part of his ongoing goal to monopolise powerful Devil Fruits

Not that this will be permanent of course, as in Tolkien’s universe it is prophesied that the trees will be revived from the breaking of the Silmarils, which contain the last traces of their light. The prophecy also refers to the flattening of a mountain range, which in this case refers to the destruction of the Red Line at End of Series

Now to the second part of the title – The weakness of Devil Fruits. I’m sure some of you have seen a theory going around which makes reference to a substance called Pyrobloine

Pyrobloine is a substance found in Seastone which is ejected by volcanoes. Given that it is present in island cloud it must also logically be present in sea cloud, which weakens DF users as normal water does. But what people seem to have missed is that the sea itself would also have a very high concentration of this substance. Why? Underwater volcanoes. Of course, made a huge deal out of on the journey to Fishman Island, underwater volcanoes will also expel this substance into the surrounding waters

The surrounding waters are of course host to something significant to this mystery. The roots of Eve. I stand by my prediction that Eve is where the Devil Fruits grow. Logically this means that they contain Pyrobloine, as it would be absorbed by Eve’s roots as they draw nutrients from the surrounding sea water. I’m currently unsure of the specifics of why this weakens Devil Fruit users but for some reason the Pyrobloine in their bodies seems to react to other substances containing it. Given that Devil Fruits affect the bodies of their users and not their souls (confirmed by Tashigi’s use of Smoker’s power after their body swap)

it would be reasonable to assume that their cells are being altered, meaning the weakening is likely tied to that. Speculative guess would say that Pyrobloine in some way affects the Mitochondria, which of course generate energy for cells and if stopped would result in the loss of their powers and energy. Given it’s presence in Skypiea it’s reasonable to assume that Pyrobloine is very easy to transfer airborne, which means it may also be the cause of DFs transferring to nearby fruits as it alters the cells of it’s new host after travelling through the air

This can also be tied to Tolkien. If a Devil Fruit were to be thrown into a volcano, what do you think would happen? The cells and Pyrobloine that cause it to have it’s power would likely return to the massive concentration of it in the magma, erasing it and permanently destroying the fruit in question. But why is this relevant?

“One Ring to rule them all, One Ring to find them,
One Ring to bring them all and in the darkness bind them”

What do you get if you replace “Ring” with “Fruit”? The Yami Yami no Mi. The Yami will be destroyed after Blackbeard’s death to prevent another like him appearing, mirroring the end of the Lord of the Rings trilogy

*Theory by Go D. Usopp

1. Why Kaidou and his men are hunting Kinemon, Kanjuro, Raizou and Momonosuke?​
2. Why is Momonosuke so important to everything?​
3. Why the Kogetsu Clan and the Minks are allies?​
4. Does Ryuuma play a role in the history between the Minks and the Samurai?​

The Boshin War was a civil war in Japan that was fought from 1868 to 1869 between forces of the ruling Tokugawa shogunate and a radicalized group of nobles and samurai who believed in returning political power to the imperial court. The dispute was over the Shogunate’s handling of foreigners since Japan’s opening of its borders in a previous decade.

The parallel I’m suggesting here makes the case for a far more devious plan. Maybe the Kogetsu Clan are like the Tokugawa, who supported the opening up of Wano to outside influences and some of the other powerful clans or maybe the Imperial Family themselves (which could set them up as joint antagonist with Kaidou) didn’t agree, suggesting that opening up the country would dilute the authenticity of the original culture.They thus rallied together and enlisted the strength of a powerful pirate, namely Kaidou, to overthrow the ruling Kogetsu Clan and take control of the Shogun monarchy. And re-instituted the Imperial Style of rule. In fact, in the Boshin War, the radicals and the Emperor were supporters of a publication known as the “Order to Expel Barbarians“. The ideas were extremely anti-foreign and the ruling emperor of the time agreed with the sentiments expressed here, and actively tried to interfere with the Shogunate.I like this idea the most because it sets up a Samurai villain as well, that could be an appropriate match for a particular swordsman. Obviously I mean BrookeWhatever the reasons, I think it’s very probable that this is the structure of Wano’s current political system. Now onto the next half.

THE MINKS AND THE KOGETSU CLAN

Our theory will take us back a few hundred years to the past to theorize the events that made the Minks and Samurai become allies. If there is one thing that can bring two races together, especially two warrior races like the Minks and the Samurai, it’s a common enemy. So I’ve been thinking on it and I’ve come up with what I believe is the common enemy. It all starts, with a ……

If you are not familiar with Oda’s One Shot Monsters, I would suggest going and taking a look at it, following the link I provided. The events are considered canon and I think it’s important because it’s entirely relevant as we go towards Wano.

I’ll summarize as I know some people are lazy. In the story, Monsters, we deal with a story about a town who was terrorized by a dragon which they thought was a natural disaster, but was the work of two criminals controlling the creature with something called the Dragon’s Horn. Ryuuma, a wandering Samurai who is just passing through. He’s misjudged, people think he’s low down crook, but in the end, the Swordsman they revered turned out to be a swine and Ryuuma was the true hero.

Now I don’t expect us to see Oda retread this story in One Piece with updated characters and settings. It has its place in OP lore, but to me the most important elements aren’t the story and the plot, but these key things.
​

• Skypeia and Zou both follow two arcs that are also very similar (Dressrosa/Alabasta)
• They both are islands where the people live at high altitudes.
• They both are extremely hard to reach
• Both involve groups of people who are connected to legends from past individuals (Norland/Ryuuma)
• They both appear to be very closed off societies at the beginning.

A bizarre statement, right? Well, there is a little bit of evidence scattered across the manga that indicates he may still be alive. In fact, he may be this guy:

It’s popular belief that this guy is Scopper Gaban, the Second Mate of the Roger Pirates, but there is no reasoning for this at all beyond the assumption that the hat he is wearing comes from Wanokuni.

There is some logic behind my thesis. Firstly:

• The entire ‘From the Decks of the World’ cover story only contains characters the Strawhat Pirates already know. They do not know Gaban.
• This means that the mystery man is also known to at least one of the Strawhat Pirates, and yet Oda hides his identity because it is very important.
• Laboon is happy. This is very bizarre given his idiosyncrasy of bashing his head against the Red Line when waiting for the Rumbar Pirates. Why is he enjoying himself?

Yorkis favourite drink is Sake and his favourite song is Binks Sake. What are they drinking in the cover page? Sake. He’s also friends with Crocus, obviously, and they are on friendly terms. The cover story shows characters celebrating the fact the Strawhat Pirates are not dead. These covers celebrate specific characters’ being alive, for example, the cover story mostly features old close friends:

Luffy

But that’s wrong! Brooks close friends are not all dead. He has Crocus and Laboon! If you connect the dots it’s perfectly plausible to think that’s Yorki, right?

But wait, isn’t he dead? – UNCONFIRMED! We’ve already had an instance in which a presumed dead character has returned, and Oda even hinted at this. Remember Sabo?

But Oda didn’t hint at him still being alive!
Oh?

The only confirmed conclusion we can actually make from his “death” is that the crew partially split up. In fact, Brook told Yorki to “treasure his life”, which indicates he would live on but would simply be unfit for Piracy. A common misconception is that everyone else contracted this disease when in fact they all died from poisoned wounds:

Plus, the virus is “unknown” and it’s clearly never explained as to whether he will die or not. I speculate that he made the journey across the calm belt and, during the timeskip, completed his promise to Laboon. Do you guys think it’s possible for Yorki to be alive? I certainly do, I think that old man (with the same hair colour as Yorki) drinking Sake (his favorite drink) with two of his friends (Laboon and Crocus) at Reverse Mountain (where he promised he would return) is in fact Yorki in his 80’s.

Note: Captain Yorki is also based on Calico Jack, his name is actually Calico Yorki. Calico Jack made a disappearance from Piracy only a few years after he became famous, he later returned from his Hiatus. I won’t go into immense details but Yorki’s own journey parallels that of Calico Jack who supposedly became ill.

Am I being a lunatic or am I making sense?

*Theory by L o g i a

If CP0’s main trio that we saw in Dressrosa has Devil Fruit abilities, there is no doubt these will be incredibly powerful powers. Afterall, given their role and likely amount of power as the ultimate shield for the Tenryuubito and Gorosei against external threats, it would be ludicrous to think they would have less powerful Devil Fruits. Of course there is the possibility that they do not possess Devil Fruits, but I find this unlikely.

In another theory of mine, I explain the significance of the name ‘AEGIS’, you can give that a read here:
http://www.onepiecegold.com/the-purpose-of-cp0-aegis/

One important thing to note is that AEGIS is a defensive ability that the Ancient Greek Gods possessed. This and other factors considered, I will rule out Logia Devil Fruit powers for the following reasons:

• Rokushiki is most effectively used when a users body is enhanced, Logias do not do this, however, Paramecia can and Zoans always do
• There is a limited number of Logia fruits Oda can use at this point

Now, as I said, as Rokushiki is a heavily body-dependent fighting style, the members of CP0 all likely have very powerful Kenbunshoku and Busoshoku Haki.

According to One Piece trivia, Oda has namedropped another Rokushiki technique called ‘Chokkai’, it’s name means ‘to bother’, although nothing more is known, whether Oda is joking or not is also questionable. If Oda is being truthful about this, having not seen this technique before, we will likely see CP0 using this. If Chokkai is real I suspect the technique will involve after images and immense speed the same way Rokuogan involved immense strength.

From what we know so far, this is a list of abilities they likely have:

• Busoshoku Haki
• Kenbunshoku Haki
• Chokkai
• Rokuogan
• Kami-e
• Geppo
• Soru
• Tekkai
• Rankyaku
• Shigan
• Combination of Haki and Rokushiki

As for Devil Fruits:
Aegis to our best knowledge has three different possible source materials in Greek Mythology. There are three of these CP0 agents and therefore I believe that they each have a direct link to every singular part of Aegis.

The first instance will relate to this man:

Basilisk Mythical Zoan – Hebi Hebi no Mi Model: Basilisk
This is because, in myth, the shield first contained the skin and hair of a Gorgon, granting it incredible invulnerability as it could use Stone for protection and manipulate stone as well as turn enemies into stone. Although the ability to turn people into stone is taken by the Mero Mero no Mi and the Gorgon-based character is embodied in Hancock, a Basilisk Zoan is still very likely and powerful

Powers:

• Flight
• Turn opponent to stone upon contact (not automatic)
• Extra speed and agility
• Size advantages
• Greater muscular power
• Regenerative ability to external wounds

Secondly, the right hand man from the long arm tribe:

Chimera Mythical Zoan – Neko Neko no Mi Model: Chimera
Legend also states that a Chimera-esque creature of unspecified appearance had formed a part of the Shields construction. The creature is likely strongly related to Chimera. Therefore it’s highly probable that Oda would use the actual Chimera for this guys powers

Powers:

• Flame breath
• Poisonous bite from tail
• Claws of incalculable strength (swords slashing?)
• Horns of incalculable density
• Enhanced speed
• Enhanced strength and power

Lastly, the tallest of the three characters:

Iron Paramecia – Tetsu Tetsu no Mi
There was a giant killed by Athena called Pallas, and another called Asterus, both of whom had incredibly strong hyde/skin that was resistant to any mortal damage. At the time of the Greeks, Iron was the strongest metal discovered, hence this is a good choice. This guy is huge anyway and can be considered a symbolism the giants in question, his ability will greatly enhance his ability to defend himself

Powers:

• Enhanced defence (absolute defence? +Tekkai + Busoshoku Haki)
• Greater muscular strength
• Power and density increased greatly
• Ability to create and manipulate pre-existing Iron
• Slight magnetic properties

Well, whether I’m right or wrong, these guys are totally monstrous, but this is a little bit of fun, hope you enjoyed! Do you like these choices of Devil Fruit?

*Theory by L o g i a

As you know Nami has consistently been fighting with the clima-tact, however i do not believe the clima-tact has reached it’s final form yet. That is why i believe Nami well gain an ultimate clima-tact.

WHAT WILL HER POWER BE
Well i have had 2 ideas

• The ability to create iron clouds and merge them with her thunder clouds, to create a destructive lightning-

-Ohm’s weapon is made of iron cloudsword

• She breaks up her new clima-tact; and straps each piece to her body. When this happens, she will be able to release thunder clouds just by moving; however she will gain a lightning tolerance and won’t be affected by the shock. She will then use fishman karate to manipulate the clouds.

I personally think both of these would be good clima-tact power-ups, since they would require little to no charge up time; something that all her attacks need.

FISHMAN KARATE-ENHANCED CLIMATACT
This clima-tact works by Nami breaking up a clima-tact(not the clima-tact she currently has) then strapping each piece to her body. With this she will be able to create different clouds depending on how she moves her body. She can then use fishman karate to create different techniques such as tornadoes, hurricanes and lightning punches

I believe this would be a good power up for Nami for a couple of reasons.

1. She doesn’t need a huge distance to be effective- for most of her attacks, she needs to keep a distance since it takes a few seconds to create lightning and in those seconds she is very vulnerable. But with the new clima-tact, she won’t need to run away from her opponents to gain distance. Rather she could run towards her opponent; by moving her body she would create more thunderclouds around her, she could then use fishman karate to use enel-like techniques by launching all the lightning clouds at her opponents.
2. Would increase hand to hand combat, Nami is really bad at this so it would help her a lot; it would also allow her to use CoA more effectively

IRON CLOUD-BASED CLIMA-TACT
This clima-tact works by creating island clouds inside itself, compressing the island clouds; then creating iron clouds, which can be turned into thunder-iron clouds to give them lightning properties. How would she make a clima-tact like this? Well if you didn’t know, island clouds are created by sea stone 

This leads me to believe that she will get a sea stone clima-tact. I believe this is very likely because the SMILE factory is coated in sea stone and when it’s destroyed Franky will most likely take that sea stone to make weapons. I also believe she will use a breath dial, as sea stone only creates island clouds when a certain compound is released due to high temperatures. With this sea stone clima-tact, she will be able to create large amounts of island clouds rapidly. Then due to the narrow space inside the clima-tact, these island clouds would be compressed and turned into iron clouds. She could then spin the iron clouds rapidly to turn them into iron-storm clouds that shoot lightning.
Here are just some of the techniques that she could do with this:

• iron-lightning blasts; same thing as her wind gusts, but with iron lightning instead.
• iron-lightning sword; creates a long sword with iron lightning that can be used to fight with
• iron-lightning island; creates an entire sky island of iron lightning; she could use her clima-tact to launch this island at opponents
• iron-lightning tornado; creates a tornado of iron lightning. Imagine a regular tornado, then image what would happen if the air inside that tornado was as hard as lightning and shot out electricity

*Theory by Monkey D Theories

Jerma 66, or Warmonger, is an evil ‘mythical’ army lead by Sanji’s family, the Vinsmokes, with Sanji’s father being the head. They are most likely very powerful, seeing Nami’s reaction. She viewed it as ‘a load of crap’, meaning that Jerma 66 was so crazy it almost seemed like the organization was sculpted out of a tall tale.

Notice their choice of words. She says ‘make believe’, with Pekoms telling her it does indeed exist. It most be widely known, and to assuage normal people’s fears, someone has been telling them it is make believe and a myth.
The influence that they have is massive. They can easily get the WG to give/change bounties. This in my opinion can only mean two things.
1. They have something the WG wants.
and
2. The WG acknowledges them as a threat and gives them what they want before they lash out against them.
What I am trying to make out of this is that Jerma 66 is a crazy strong organization that is feared by the WG and is powerful enough to be considered a myth.
Now, to Capone. Capone has been in Big Mom’s ranks for an unknown amount of time. He is the leader of the Fire Tank Pirates, as well as a Mafia Boss. I have previously theorized about him betraying Big Mom, and I’ve been starting to think about a few things. What does Big Mom want that Capone have, or what she may have that Capone will want in the future? I think Jerma 66 may possibly hold the key to that.
Right now we do not know much about Jerma 66 other than what we have already been presented in earlier chapters. But, I am leaning towards Jerma 66 having something the WG wants, since they would have to be absurdly powerful to rival them. I started thinking about the wedding/tea party. We don’t know much about the tea party, but I am assuming that they would be lavish parties that took a long amount of time to plan. Capone may have join once he heard that Jerma 66 may soon be affiliated with Big Mom.
What does Capone want from Jerma? He may want to take over and use it to ascend to a higher ranking in the pirate world, or they may have something they have.

*Theory by Fishman Ibra

Alright, I would like to premise this theory first with a statement that I always thought that Luffy and his allies would ultimately clash with the World Government and the Marines at the final war (excluding the final battle with Blackbeard)

But, some developments happened along the way and kinda made me think of possibilities so, I would get this out of the way immediately:

The Marines (at least some of them) would breakaway from the World Government and execute a Coup d’Etat.

Now this faction would be very different from the Revolutionaries.

The Revolutionaries wanted to overthrow the government and got no problem affiliating themselves with outside forces like Pirates.

But the Breakaway Marines (we will refer to them as X-Marines) are the guys who still detest pirates, the same way they detest the World Government.

There are several instances in the manga why this thought came to my mind.

First is the apparent disappointment of the Fleet Admiral over the decision of the World Government.

Second is the desire of Admiral Fujitora to defy the government privateers called “Shichibukai” system and his obvious disdain for the World Government.

Now, the other reasons I have are just a speculations, but I believe I got good grounds for it..currently in Zou arc, some parts of Sanji’s backstory had been revealed, and it was said that this “Vinsmoke Family”, which Sanji is a relative of, leads a group called “Warhouse / Germa Double Six”

Now with the involvement of Capone “Gang” Bege, who obviously had been inspired from Al Capone, a famous Mafia Leader, it would be fair to assume that Capone was hired to bring the news to Sanji by another Mafia Group.

Which is kinda confirmed in a way because they are said to be a “Family of Assassins”, well either way, moving on….

With “Germa 66” name as well, I would assume that Oda used this name in order to reference a group/organization from the movie “Kill Bill”, by Quentin Tarantino (Oda loves Tarantino Films)

The Crazy 88, which is led by a Mafia Leader / Underworld Leader.

(wouldnt be surprised if the Vinsmokes hide their faces like this to hide the eyebrows. LOL.)

I’ll dive into this topic in another theory (and Germa 66 connection to a card game), but lets just say, the head of Vinsmoke Family lured Sanji into doing what he wants by using someone Sanji loves as a bait.

The point i’m trying to make (which is kinda confusing coz I rambled on) is that the Vinsmoke Family is a Mafia Family.

I’ll just get straight to the point.

Each of the Gorosei leads their own organizations, so that makes it 5 organizations including the Germa 66 and Cipher Pol.

Simply said, in the game of chess, those 5 organizations are the real “guys” of the World Government.

The Marines?: Pawns, disposable pawns who always get fronted in battle and dont know the real “identities” of the World Government, especially the Gorosei.

So I believe some Marines would breakaway from the World Government and start a new faction.

So in the final war, we have:

1. The Strawhat Pirates and its Grand Fleet.
2. The Blackbeard Pirates and its Grand Fleet.
3. The World Government (Science Division, Germa 66, Cipher Pol etc.)
4. X-Marines.

And yes, I don’t believe the Red Hair Pirates and the Revolutionaries would be there for the Final War…

*Theory by beck

I would first like to state that there are a few things that make the StrawHat Grand Fleet different then most fleets we’ve seen so far

1- They don’t stay together the entire time, each division of Luffy’s fleet travels the New World on their own adventures which will help them develop in different ways.

2- They all joined Luffy not out of fear but out of respect

3- A lot of the individual captains/commanders have their own goals/dreams, they might not be as big or important as the straw hats but they are dreams

1 Cavendish wants to be a star and a great pirate known all over the world
2 Bartholomeo wants to be of use to Luffy and help him and the crew in every way
3 Sai wants to raise the happo navy to greatness
4 Ideo wants to be a great fighter kinda like Ussop wants to be brave warrior
5 Hajrudin wants to rebuild the giant pirate crew
6 Leo and co want to help Ussop and Luffy as much as Bartolomeo
7 Orlumbus seems to love adventure like Luffy

Now their potential growth is the main point of this theory

But first i want to bring up one of my theories on kings haki and haki in general. Now i believe the reason why we have not seen a Marine or any strong member of a Yonko’s crew with king haki is because they serve under someone, kings do not serve others. Also ranking systems are in almost every crew or organization in One Piece except the Straw Hats. In this way the Straw Hats are all on equal ground with Luffy, they do not shy from making their opinion known like in most crews, Luffy has been shown to take their advice when making important decisions like with Ussop on Water 7 and Sanji here on Zou.
With this freedom i believe that the Straw Hats and fleet members are not limited in how strong their haki can be trained and developed. I believe that the fear to constantly please and obey Yonkos like Big Mom and Kadio limits the overall power of someones haki because haki is a form of willpower and fear weakens willpower. In saying that I do not believe Yonko crew members are weak just not as strong as there maximum potential. The Straw Hats and fleet do not serve Luffy like most fleets serve there captains, they assist Luffy in his quest to become pirate king, this change in mind set can cause many of the main fighters to develop new attacks and unlock higher levels of haki like with Ussop when unlocked his coO haki.

Sai could improve his dragon drill tech adding the power to his staff gain kings haki like Chinjao.
What if Hakuba is Cavendish’s personal haki demon like the Zoro has and he learned to control him?
Barto could learn to crate more then one barrier and shape them into weapons animals or other shapes..
Others could develop spiritual power up like Sanji’s fire, Brook’s ice, Fishman Karate and unknown tech

Please let me know what you think below
