before we get really going I have to say a few words that you will hopefully take to heart. There is no way that you don't disagree with parts of this theory because it tries to look at powers in One Piece in a completely different way. Needles to say that only Oda understands what is possible in the One Piece world and how he justifies the powers he creates. Though we are so far into the series that I estimate that Oda gave us enough to puzzle out what is really going on with devil fruits, haki, the Grand Line and what have you. I am not saying that I have the perfect answers, far from it. This is an attempt to make sense of "One Piece logic" and I don't say its the correct one, but that the angle I will take is undeniable. To understand the presented ideas we are going have to go into abstractions and rethink our assumptions. Our road will include implications and following things to their logical conclusions. I promise you that if you keep an open mind this theory will be compatible with your understanding of One Piece.
Without further a do, let's begin!
The world of One Piece
We have encountered many things within the One Piece story, giant sized creatures, magical fruits that give one superhuman abilities, oceans with unbelievable currents and extreme weather conditions. There are abilities to get in tune with your own aura, going so far as to be able to foresee the future and defeat enemies without touching them. You name it, One Piece probably has it but can it be that there is a common force that connects them all? Don't worry, this will not go anywhere nonsensical(I hope at least ).
I can't write anything as close as brilliant as @CAMUNAI 's theory about what devil fruits are. I was following many plot lines and had a lot of puzzle pieces with dead ends. I knew for example the importance of electricity when it comes to Conqueror's haki but couldn't figure out why it was related. So I can't give enough praise and credit to him/her for making me understand what devil fruits really are.
What Camunai discovered is that devil fruits act according to physics and are basically containers of electromagnetic energy(radiation technically but that would be even more abstract). If you hear this for the very first time you might be skeptical but I am telling you this is almost a certainty. I will show you what the manga has been stating soon enough and it is the key in understanding the world of One Piece. Let's begin with the first component which is magnetism and in particular magnetic fields.
What is magnetism?
Magnetism is the natural phenomenon of attraction and repulsion. Magnets are bodies(one of the first discovered and most commonly found are magnetite)that emit a magnetic field which repels and attracts objects that are in its influence. The earth is a classical case for a magnet and therefore a magnetic field, which is symbolized by the lines around it.
A magnet always has a north and a south pole. The flow of the magnetic field goes from the north to the south one. We are still in middle school territory here and this all feasible for a mangaka like Oda to understand and incorporate into his work of fiction. We know that Oda knows about this phenomenon because our journey is mostly occurring in the Grand Line and that is where things aren't how they supposed to be.
The Grand Line itself is a magnetic anomaly which has various minerals that makes it impossible to determine south or north, hence the usage of Log Poses.
Buggy & Shanks confirmed that the One Piece world has an "official" north/south pole(is this a hint to One Piece? Possibly). That is a given in a world of navigation but nonetheless its interesting that Oda pointed this out before we entered the Grand Line, his mind was already on the subject.
Log Poses pick up on a magnetic field from the current island you are on. (I don't think the pun is lost on Oda that we follow a "current" that is influenced within a magnetic field, which is a clever way of saying "electromagnetism") Once you travel to the next island the process repeats itself. What has this to do with the powers of One Piece you might ask? Let me begin with something that happened within the very same chapter where the magnetic field of the Grand Line was introduced.
Crocus tells us that Luffy has quite a "mysterious aura" about him. Crocus confirms to know Roger but makes no remark about Luffy's straw hat(its to be expected that some people just wear one). This might sound like a lose connection and you would be right to think so but this is just the beginning. Oda is connecting the concept of Log Poses who track an "aura" to the one of a human. How does the "Log Pose story line" continue? It continues with the introduction of "Eternal Log Poses".
They also pick up the magnetic field of an island but remain with the "poling" of its respective island. Does this remind you of something that we have encountered in the very same Baroque Saga but Oda intentionally didn't reveal its true purpose yet?
Oh yes, we have picked up on Oda's trail and Vivre cards are confirmation that human beings have a pole that can be tracked. Vivre cards act the same way(they move towards their "target") as Log Poses do and the reason the second works is the unique magnetic field of the Grand Line. Maybe it is the same for Vivre cards and we have very good reasons to think so. As a side note, is that the reason why Oda didn't reveal the meaning of the Vivre card in the Baroque Saga so it wouldn't be too obvious that the "2 new things" are related? I think so but let's continue the trail. Where can we find the vivre cards?
There is something in the world of One Piece that is related to magnetism which enables you to track islands and people. Oda gives us a major clue that will hopefully rock your socks off. Lola tells us that you can create vivre cards through the usage of "fingernails". You might be thinking(like me before I researched this) that there is a secret ingredient that can only be found in the Grand Line but there probably isn't. If you would have to tell me a trivia about finger nails, what would it be? What is the one thing you know about finger nails which is important for your day to day life? Its when you have white spots on your fingernail it means you have a calcium or magnesium deficiency. What did I said again was the main "material" which had magnetic properties?
Its magnetite and look at the Carbonates section. Oh indeed, magnesium is magnetic(the name already shows a relation). We have gone full circle with basic middle school physics and if you are a keen reader you have probably picked up on the "ore" reference and yes, it is important to the deepest lore of One Piece.
This might be the material with which you can create Poneglyphs. Though, this is another rabbit hole that I don't want to go down tonight, except for a small detour. Let's solve one of the older mysteries in the series that is often taken for granted.
This is confirmation that the Poneglyphs aren't simple stones. They have a magnetic aura that can be tracked as well. After all, Roger found this when nobody else including Enel could. Of course Roger didn't hear the "aura" of the gold but that of the Poneglyph. Later on we get to know that he could understand the "voice of all creation" and whatever this explanation entails. I think that saying its a "natural ability" while stating its not haki is missing the point. That is what haki is, it is your will/emotions manifested through an agent(electromagnetic energy) and your control of it. We are going beyond what is stated in the source material now and have to take away the blinders that disables us to see the whole picture. I don't blame you for sticking to your ideas but mind you, why did Luffy "unlock" the "voice of all creation" after mastering haki? Is Oda just retconning everything or is there a design that has a solid internal logic? Mind you, the mystery about Roger and the Poneglyph was dropped in Skypia. It confirms that there was a method that Roger used to found the Poneglyph and read/write in the Ancient language. It is to note, every living thing has an aura that can be tracked via Vivre cards("card of life";life is haki, hence why every living creature has it). The islands on the Grand Line have unique "auras"(magnetic fields, same thing) that can be tracked through the usage of Log Poses. The same is true for the Poneglyph that Roger found because it emits a certain type of energy. From now on, I use the words electromagnetism(both components), aura, energy interchangeably because they are the same thing in the One Piece world.
The missing pieces
Let's continue with the missing pieces and put them all in the same basket. I am talking about the nature of the Grand line, haki, races/tribes and devil fruits. You might be thinking that they are completely different things but once we connect the last dots we notice that they are all related and have a common cause, the magnetism of the Grand Line. Have you ever noticed that all races outside of regular humans originated from the Grand Line? Oh yes, I am going there. You are probably thinking to yourself "Oda didn't thought about all these things beforehand! He can't have his entire story down 20 years before he writes it." That is true to a certain extend but mind you, do you really believe that Oda didn't know in which direction his series would go? He already introduced Fishmen in the East Blue saga and told us that they originated from the Grand Line. I don't claim that he had the entire story down on day 1 but certain things like devil fruits, different races like giants, prehistoric islands where clearly intended from the beginning. Today we know about the quality of Oda's imagination but that wasn't a given. He found a solution to this problem and how he could incorporate his ideas into a world where these things are possible, hence why he created the Grand Line.
This is the first thing that we seen once we have entered it. This isn't a normal place but where the impossible is normal. It is a place more a kin to the "Bermuda Triangle"and this is how it is advertised. All the races we have met originated from the Grand Line which leads me to believe that the Grand Line is the reason for this evolution. The magnetic field that exists in the Grand Line caused this change and mutation. It is the same reason why certain tribes of their respective islands learn a specific type of haki.
For illustration, does the magnetic field of Wano encourages the learning of "ryou"? Ones aura is being influenced be the "aura" of the island and an adjustment of ones"poling" occurs? Is that why tribes like the Kuja and races like the giants evolved the way they did in the One Piece world? Is this why the Supernovas(captains only because Zoro/Killer followed theirs) are drawn to the Grand Line, the place where the aura(races, devil fruits, specific haki like Luffy) they posses originated from? This is a big claim and I still haven't connected all the dots yet. I understand if you at this point are not buying the whole premise, we haven't talked about the last mystery yet, devil fruits.
"Big guy, did you forgot about "ELECTROmagnetism"?"
We covered magnetism up until now but we haven't touched on the 2nd component yet that is fundamental in understanding the world of One Piece.
Electricity and magnetism are related and both stem from the phenomenon that is "electromagnetism". For simplicity sake we are only focusing on how electricity is influenced within a magnetic field. This sounds more complicated than it is if we don't go into any math. Let's illustrate this visually and you will get the drift soon enough.
The human body is like the earth a magnet. We have two magnetic fields, the inner zone shows the magnetic field of the heart and the outer of the body.
Does this remind you of something within the One Piece world? That your mindset, beliefs and emotions can manifest itself in certain powers? That your emotions shape reality? This control of your own "current" within your magnetic field is what is called "haki". This of course is a concept that Oda has from the real world. Your brain uses electricity to give signals to your body and hence your emotions, will manifests itself in your physical competences. The inspiration is clear and Oda is right to equate haki with electromagnetism. It is simply true and our ancestors accepted this for thousands of years. That for example light which is emitted by the sun is the source of life on earth. Light is a form of electromagnetism and the justification in terms of Anime logic is quite sound. Its even less abstract than most Shonen powers and is based on common knowledge.
Rayleigh is literally calling it "aura"(Crocus foreshadowed this earlier) as well but there is something way more tangible to prove the claim. What does one perceive when observation haki is being used?
This is the most important piece of evidence to support this theory in conjecture with another reveal. It is indirectly confirming some of the premises of this theory if we assume Oda didn't made some sort of mistake here, which I don't think he did. Oda shows us Luffy's perspective of observation haki when he is about to learn future sight which doesn't make much sense. He would show us what Katakuri saw with Pudding if the reveal was about future sight but he didn't.
He showed us something that we haven't seen before. We see how devil fruits and haki manifest in people. Let's look at the reality and see what Oda tried to show us.
I don't want to rush it here and really want drive this point home. Katakuri is using haki and his devil fruit ability but his body isn't changed into mochi. What do we see?
All of the energy looks the same and both(devil fruit/haki) have the same color , which means they emit both the same energy that is called willpower/electromagnetism. If they would emit different types of energies we would clearly see a difference in colors but they aren't. Why devil fruits emit the same energy as haki will be explored in the next part which will be linked at the end. Let's just say that haki is required to cycle them in the first place. For further confirmation I promised you another piece of evidence which confirms the premises of this theory.
Oh yes, do you see it? Humans who aren't using haki or use devil fruits have a white aura to them. Katakuri's body wasn't white but it had the same color as the dust in the air. I tried to think of many explanations for this pattern because it must mean something. Oda didn't unintentionally made the dust the same color as devil fruits/haki different to "normal" humans beings, Oda is connecting the dust with those two but how? Why can't we perceive the island but the dust?
There is a magnetic field within the Grand Line which screws up navigation and Oda showed us a swirling motion before. One doesn't perceive the magnetism of the island which is shown as black but the "current"(in this instance grounded dust in the air which causes friction) that is emitted by it. If "energy" is released within a magnetic field(islands, people with haki/devil fruits) the "grey" color can be perceived through observation haki. Oda is connecting devil fruits, haki and islands himself through the usage of the same color and how it functions.
I am going to show you now one of those "dead end puzzle pieces" I had before reading CAMUNAI's theory. I knew there was a connection because of the pattern but I didn't had any solid reasoning. This is from chapter 1 after Shanks used haki for the very first time.
Shanks uses an unknown ability and creates a whirlpool that has a swirling motion. Did Oda had this idea from day 1, that the swirling motion is related to abilities? Can it really be?
Yes, they are all connected and are the same thing, electromagnetic energy. Humans and others are able to use a current/swirling motion/electricity within their magnetic field to create ones respective ability. If one ate the mera mera no mi and uses its wavelength it results in fire. The same is true if you use the wavelength of your body which results in haki. Let's listen to a person who studied his devil fruit and was able to alter its effectiveness.
Chopper confirms that devil fruits emit a wavelength that can be manipulated to alter its power. This is a kin to haki and related to the magnetic fields of humans and the strange place that is the Grand Line, the place where haki, devil fruits and different races(they have different traits which is another way to say "ability") originated from.
I know this is a lot to take in so let's take a small detour before finishing up on this segment with the last connection. Let's talk about how Blackbeard ate two devil fruits. After I have done research for this theory I found a solution that was aligned with the head cannon I had for years. For some reason I thought that Blackbeard consumed Whitebeard's heart and that is how he obtained the gura gura no mi. After all there was a reason why Whitebeard took these two hits so close to the heart and Blackbeard covered Whitebeard's body because he doesn't want the world to know how he does the trick. The most gruesome body part would probably be the heart and it reminds me of some barbaric practice where it was believed that one could obtain the power of the enemy through the consumption of their heart. I have already shown you this but let's look at it again with that in mind.
The heart is directly related to electromagnetism and in particular electricity(megahertz). I think Oda might have seen an illustration like this and came up with a justification for how devil fruits would operate in a human body. We will return to this very soon but it might be fun for you to think about it yourself and see if we find the same answer.
I promised you an undeniable connection to the swirling motion and its relation to "power" in the One Piece world. It would be too much to go into every ability in the series and frankly I wouldn't want to try explain everything but I am going to give you a case study for this theory's premise.
Is it a coincidence that all the Vinsmoke children posses these swirling motion eyebrows when they exchanged their emotions for their respective abilities a kin to devil fruits? No, the latest chapter(C.924) proves that emotions/haki/aura/will manifested are necessary in creating devil fruits but that is for another theory where I will go in depth about the swirling motion and in particular Vegapunk. The hint is the devil fruit within the Pacifista, which is the yami yami no mi. Light is a form of electromagnetism and this is what Vegapunk has discovered. To finish the undeniable connection between the swirling motion and "powers" in One Piece I would refer to Oda's words in an SBS.
This is not a troll answer but one of the greatest keys in understanding the powers in One Piece and Oda makes the connections for us. He explains to us that he believes the swirling motion(circular energy) to be a truth of life itself. Everyone "lives in circles" and he connects objects(sun,moon & earth) with humans(Sanji) and this is how he rationalizes the pattern. The same "tidal waves" we can find on devil fruits are seen with the eyebrows of the Vinsmokes and they represent "circular energy". Oda is even using the word "gravitation"(which is true, it is one of the four fundamental forces of nature. Another one of those four fundamentals is electromagnetism) and the importance of it will be cleared up in the next segment. With the ground work laid we can finally talk about devil fruits.
Now that we have done some readjusting the concept of devil fruits falls into place. They are retainers of a certain electromagnetic wavelength(aura, will, emotion) that one can consume. This wavelength is likely stored in the heart and enables you to use an ability in exchange for being a "hammer". Isn't a hammer made out of metal, which is a classic example for being influenced by magnetism? Whatever, another coincidence probably and no hint at all! How does this usage of a specific ability function? Well, we are neck deep into magical territory but I think there are hints to figure out how it could work. I have showed you the two magnetic fields of the human body and this might be an elegant solution for the problem. Especially why one can't eat two and maybe how Blackbeard was able to do so.
I think that the inner magnetic field of your heart changes and adapts to the wavelength of the devil fruit one consumes. Your outer magnetic field is the one from your body and the control of this area is what we call haki.
Luffy takes the energy out of his body and emits "electromagnetic waves" that are clearly seen(again same waving motion a kin to devil fruits). Perceiving your magnetic field is what observation haki is and so forth. I won't bore you with long explanations because I put many theories about the subject out and would only repeat myself. Though if you are interested in the subject here is my unifying haki theory.
We have been talking about devil fruits and how they are related to electromagnetism/haki/aura. Once you consume a devil fruit your inner magnetic field changes and a particular ability can be used. Both of your fields require energy and draw it from your body. This would explain why rarely people will even learn haki because its counter intuitive to "waste" energy. Only in extreme circumstances would this ability be even expressed.
Lucci is calling devil fruits a "curse" because it drains something from you the user in exchange for a specific power. Its not simply that you are a "hammer" but this energy has a cost to it. Also, Blueno is saying that "Grand Line scientists" have proven the "ability transfer theory" which implies that in fact devil fruits are from the Grand Line. If anybody would know this and hadn't forgotten it would be the world government.
Another relevant thing is that Blueno brings up the consequences of eating two devil fruits. This theory claims that devil fruits and haki are both electromagnetic wavelengths(hence the swirling motion) and we know that haki negates devil fruit abilities. Wouldn't this be expected if they are the same? That one can't "overwrite" the other and can't share the same place, therefore one pushes the other out? Though what would happen if you consume two of those energies within your body? Well, the same thing, both energies would push against each other and because you have now 3 wavelengths(yours that is in symbiosis with a devil fruit but the 3rd will push against your devil fruit and can't fit in the same place) fighting each other you explode. With all that being said, how did Blackbeard eat two devil fruits? He has two hearts and probably more inner organs than we know. I can see him having multiple stomachs and this is what Marco is referring to.
Blackbeard has shown that his body is not ordinary and he probably has shown this by eaten 100 cherry pies in one sitting or something of the sort which shouldn't be humanly possible. Let's return to the "curse" and some more exposition.
Devil fruits have a "gravitational force" and again, we see the electromagnetic waves that we are now very familiar with. They are attracting/repelling something within their magnetic field that is being contained in them and are the key to their functionality. To confirm our hypothesis about devil fruits we have to consider how you lose its powers besides haki, maybe we can find another truth here. There are three known methods: haki, yami yami no mi and falling into the sea(sea stone mimics this effect, so for simplicity sake I combine the two).
Blackbeard connects his devil fruit to gravity which Kaku told us is being emitted by devil fruits. What is darkness? It is the absence of light and not really a thing. 0 cars are not cars but the absence of cars. That is why he can't transform himself and take the shape of darkness because its more of a concept. It is the negation of light, which I already told you is a form electromagnetism (kudos again to CAMUNAI for this point!). Boom, it confirms that devil fruits are a "form of light" which is electromagnetism.
"Why does your power get drained when you fall into the sea? (sea stone as well)"
If we accept that the wavelength of your heart changes according to your devil fruit and that it consumes the energy of your body in exchange for the ability what would happen if your "devil" goes wild? What if he comes in contact with something that disrupts the wavelength so much that you are unable to use haki?
If you have eaten a devil fruit you lose your ability to use haki in sea stone cuffs. Doesn't this prove that they both are related somehow? Isn't this exactly what we would expect of the inner/outer magnetic field of the body and the symbiotic relationship between them? We are getting deep now and its getting more and more abstract. It is difficult to formulate the next segment so please give me some leeway here. Let's write down some premises to find the common denominator.
- Devil fruits have a gravitational force
- They use the energy of your body for their respective effect
- Devil fruits are stored within the heart of your body(inner magnetic field)
- Haki is the control of your outer magnetic field and uses the energy of your body as well
- Devil fruit users can't use their respective ability or haki in sea stone cuffs
- You can't use devil fruit abilities and haki in the same area
- When devil fruit users come in contact with sea stone their energy generally gets drainedSea stone accelerates the energy that your devil fruit takes from you and in the process disrupts the usage of haki/devil fruit. That is less abstract and actually comprehensive. Is it because sea stone is a magnet which attracts the electromagnetic energy of your devil fruit? That would exactly create this effect because it pulls the electromagnetic energy of your devil fruit out of your body, it drains your stamina and you can't any longer use your devil fruit. Though it also disrupts your usage of haki, how is that? I haven't told you the entire truth and the exception to this rule that I would be remis not to mention. It is about the usage of the "flaming pattern" and being able to perform both devil fruit and haki at the same time. Camunai's theory answers that question with "resonance" and gives a good perspective on the subject. I would just encourage you to read his theory if you want to know more about it.
The point is that after a certain amount of time ones aura resonates with the aura of your devil fruit(both electromagnetic fields mix) until your able to one day use both in the same area. Case and point is Gear 4 and how Luffy is able to remain with the properties of rubber while using haki(something Doflamingo has never encountered before). That proves your auras can in fact mix and be used at the same time which confirms why Luffy can't use his haki while in sea stone cuffs. When your aura starts to merge they are tied together and if you are wearing sea stone cuffs you lose the ability to use both. The higher the dosage and the magnetism of the sea stone cuffs the more energy gets drained.
Let's finish up with haki and in particular the color of Conqueror's!
Color of Conqueror's
We are on the last spurt and I hope you will enjoy this part greatly. This is where some crazy shit will be revealed that you have noticed tens of times but thought it was just a "stylistic" choice. Electromagnetism explains everything about haki and especially the most elusive that we will focus on, the color of conqueror's(CoC from now on). We have talked previously about aura and every living being having one. Controlling this is what haki is and it can typically be divided into two shades. Though there are some individuals who have such strong auras that they are able to emit it in a particular way.
It is to create an electromagnetic pulse(EMP for short) to shut down the brain of those who's aura is far beneath theirs.
Only those with a strong enough aura relative to the user can resist it but there is more to it. If we understand that haki is within every living thing why doesn't everyone have it? By its nature it shouldn't something different and its "typically" divided into two shades but why can't certain people use it?
Sanji explains it to use, it is talent. This might sound like a cop out but really, CoC is the emission of electromagnetic energy and this shuts down the brain of people with a "weak aura". It is electricity and requires a huge wavelength to be effective. I think that everyone has CoC but its useless for most. Only those who have a strong enough wavelength can "impose" their will onto others.
If a normal guardsman has 10 "douriki"(again, a waving motion) you need maybe 100 or 1000's to impose your aura on someone else. That is talent and the "disposition to stand above others". Though there is more to CoC and its relation to electricity and in particular what I call "black lightning".
Kaido is able to incorporate CoC in his fighting style and has a named attack called "Thunderclap". He uses his wavelength around his club and concentrates it to create "black lightning". In return this attack is able to one shot Luffy, who is on Katakuri level. That explains why CoC is the most feared ability on the sea because like the primitive people used to say "fire is power" and they considered lightning to be fire. Lightning(electromagnetic energy) is the absolute representation of power in One Piece and justifies this fear. Oda hinted on this evolution in Dressrosa and showed us where CoC is moving towards(Don Chinjao and Luffy talked about exactly this subject).
Luffy has already shown that he possesses a control of CoC even outside of the EMP usage.
Even though he didn't reach the level yet where he can use black lightning he will in Wano. I have talked about this already in the haki theory posted so I will not repeat myself too much here. Instead, let's put on the 10th layer of tinfoil! If we follow what CoC is to its logical conclusion we understand certain things can be a byproduct of it, something like this for example...
Right after they become heated and the conversation takes a wrong turn the air gets charged around them and the weather changes.
Look at them clouds! Two of the best CoC users emotions go stormy and the atmosphere changes accordingly. This is a foreshadow into what is to come on the top level. We have encountered this phenomenon a few more times and every time it is related to a CoC user.
If that many big shots gathered in one place and in particular Roger this could have caused the raging weather. Though there is even more. Marineford, Punk Hazard, even Ennies Lobby. The weather can get altered through emotions, will and therefore CoC. Though I like to think about this scene because its the most ambiguous. This is what occurred right after Luffy was captured by Buggy in Logue Town.
The weather instantly changed the moment he was caught on the execution stand. Did Luffy save himself after he was captured?Doflamingo saved himself similarly but with the other component of CoC. The easy solution of course could be Dragon's CoC, who's haki is causing storms wherever he goes. Is this why the "D's" are known for causing storms? Their island had a specific magnetic energy that enhanced the CoC of the citizens? Is that how they advanced their technology thousand years ahead of their time? Maybe, emotions are definitely essential in the manifestations of abilities but that is for another day.
Next time, we will talk about "sad smiles".
Anyways, I hope you enjoyed it!
EDIT: The follow-up is uploaded.
