ONE PIECE GOLD
When we were introduced to Artificial Devil Fruits I didn’t really think about what this actually meant. It wasn’t until recently when I saw Sheepshead using horns for arms that I thought, how’s he doing that?! Then I thought, well Vegapunk and Caesar must have some scientific knowledge of how Devil Fruits work, but that must mean Devil Fruits are made logically and scientifically, and aren’t supernatural. This got me thinking, how can all these crazy ass Devil Fruits not be supernatural?! It was from this question that I started this theory, I undertook a scientific approach as to how Devil Fruits are made and how they work.
It’s a LONG theory as I wanted to be as thorough as possible, taking a step by step approach. From this I drew a number of conclusions, ones which made me want to analyse Blackbeard through new eyes. After doing so, I now believe I know how Blackbeard can use more than 1 Devil Fruit. Let’s begin!
Let me start with a few propositions that I’ll explain fully throughout the theory:
1) All Devil Fruits are made from a specific aspect or aspects of the One Piece universe.
2) Devil Fruits are created by a Devil Tree, the fruits are created through a scientific process with scientific components.
3) Devil Fruits need a Soul and Body to fuse/conjoin with for the Fruit to come to life.
I imagine some of you will be wondering why I’m explaining Devil Fruits as ‘aspects of the One Piece universe’. The main reason is because all Devil Fruit abilities can be explained by our understanding of the One Piece universe, both scientifically and creatively. I’ll explain this further by labelling 6 aspects of the this universe which are used to create Devil Fruits:
1 Biology (life forms)
A Devil Fruit that’s formed using the biology of a specific life form, basically DNA and other biological aspects that make a particular existence. This means Zoans and Ancient Zoans, i.e. Lucci’s Leopard Fruit.
2) Chemistry (chemical compounds/elements etc)
A Devil Fruit that’s formed using atomic structures and other aspects of chemistry that account for the inanimate matter of the One Piece universe, i.e. Luffy’s Gomu Gomu no Mi, how he can stretch etc.
3) Physics (natural laws/physical occurences of the universe)
This aspect is abour matter and it’s motion in relation to the OP universe. This being phenomena like electricity/gravity/light, i.e. Issho’s Fuwa Fuwa no Mi, being able to attract mass to mass.
Until now, the aspects I’ve mentioned can all be attributed scientifically to real life, the next two aspects will be in relation to human creation. However, I will explain how all Devil Fruits the next two aspects can be explained by biology, chemistry and physics.
4) Artificial Life Forms (mythical creatures)
This aspect basically explains how Mythical Zoans are created, by using myths humans of One Piece have created and scientific components to create them. I will now break down Marco’s Phoenix Fruit. A Pheonix takes its biological attributes from birds. The creation of wings, birds feet, a beak etc, and how they function. His blue flames have the properties of actual flames. The regenerative aspect will be based on human’s ability to heal wounds, essentially the idea of restoration is restoring that which already existed. Another example is Sengoku’s Daibutsu Fruit using shockwaves, this is an example of the physics aspect.
One question you may ask though, how do you create flames that don’t burn? I will answer this when I explain how the Devil Tree works.
5) Artificial abilities/actions
This aspect will draw upon the first 3 aspects once more, but the question ‘how is it possible’ will be asked again, therefore the ablilities here are those which could artificially work in theory (again this will be clear when I explain how the Devil Tree works).
First example, Wapol’s Baku Baku no Mi, this is an interesting fruit because I believe it mirrors a function of the Devil Tree. Wapol can take any physical objects/beings in the world, eat them, conjoin/fuse them, and create artificial objects, be them weapons or toys. A unique Fruit indeed! It’s this type of fusion that I believe the Devil Tree is capable of when creating fruits.
Another example is Kanjuro’s Devil Fruit, again I think it’s based on an aspect of the Devil Tree. Kanjuro can bring drawings to life, artificial creation. Be it a bird flying or food to eat, Kanjuro can create life forms or matter with real physical functions. The Devil Tree is similar because once a person eats a Devil Fruit the Fruit has life through the person, and therefore has physical functions, i.e. Luffy being able to stretch.
The last aspect is vitally important, because it’s not something, as of yet, we can scientifically confirm as existing. Philosophers have theorised for hundreds of years on this subject and it’s hard to believe we’ll ever be able to know. What I’m talking about is Souls. However, Oda has confirmed through a few different characters that Souls exist, but actually shows us how they work. In other words, in the universe of One Piece, Souls work scientifically.
6) Spirituality (Souls)
I’m going to analyse 3 characters who will shed some light on how Souls function in One Piece. They are Brook, Gecko Moria and Trafalgar D. Law.
I’m going to start with Brook and the Yomi Yomi no Mi, beginning with a quote from the One Piece wikia:
‘(The Yomi Yomi no Mi) enhances the users Soul to the point where they can come back after dying once, remaining alive until sufficiently damaged, and to use several other soul-based attributes’.
Brook’s body clearly has no brain (mind), so he definitely has a Soul. One could attempt to counter this by saying Brook’s Fruit has an ‘Artificial Life Form’ as humans have created the myth of humans having Souls. I’d counter by saying you can’t
scientifically create something that doesn’t physically exist (in terms of biology, chemistry and physics). We know Brook has a physical version of his Soul because we’ve seen it leave his body, to our knowledge we don’t know the make-up of Brook’s soul, but we do know it exists. Therefore, I believe spirituality is a branch of science in One Piece. I guess you could say his Devil Fruit is magical but in the next two examples I’ll explain why I don think this is the case.
Secondly, I’ll explain Moria’s ability, again with a quote from One Piece wikia:
‘(Kage Kage no Mi) gives the user the ability to manifest and control shadows, as a tangible physical form… the shadow follows the soul of it’s owner’s movement’
The word to focus on here is ‘physical’. Assuming their is no such thing as a Soul in One Piece, why would Oda allow shadows to mirror a human’s mind? I think it must have to do with how Souls scientifically exist in One Piece. Usually a shadow ‘follows the soul of its owners movements’. Let’s assume ‘soul’ is the wrong term here and a shadow is actually just your your body blocking out the light, why would Oda allow a person’s shadow to be a second personality of that person? I think this has to be beacuse in the world of One Piece shadows hold a conjoined physical relationship with a person’s Soul and Body.
And lastly I’ll explain Law’s Devil Fruit, again with a quote from One Piece wikia 
:
‘In the case of switched souls Devil Fruit powers are maintained within the original physical body’
This is in relation to Law using his Ope Ope no Mi to switch either Souls or minds between two different people. The Soul notion is backed up when Sanji used Kenbunshoku Haki in Nami’s body. This Haki has been described as ‘spiritual energy’ and I think it can be scientifically explained in the field of spirituality. I also think Busoshoku Haki and Haoshoku Haki can be explained using the Soul. In some kind of scientific way people with strong fighting Souls can harden their body via the Body and Soul connection and those with Haoshoku Haki can use their Soul to intimidate etc.
In relation to the quote, the fact that Law cannot operate on Devil Fruits when switching bodies implies that once a Devil Fruit has fused with a Body it cannot leave it until the Body has no Soul. Chopper didn’t lose his Devil Fruit when his Soul was swapped with Franky’s because Franky’s Soul kept it connected to Chopper’s Body.
The Devil Tree
I believe Devil Fruit’s come from a Devil Tree for the same reason that has been proposed in numerous other theories. It’s because biblical named Trees exist or have existed in One Piece and it just seems logical a Devil Tree will exist.
From my research I’ve come to the conclusion that the Devil Tree is God-like, I think it’s a omnipotent and omniscient Life Form that is connected to everything in the One Piece universe. I believe the Devil Tree functions like nothing else in One Piece and is capable of using all aspects of the One Piece universe like ingredients to operate with when creating Devil Fruits (similar to how Law can operate in a sphere, in fact I believe Law’s Ope Ope no Mi is scientifically linked to this process). I then believe it scientifically fuses/conjoins the aspects of the One Piece universe together to create the Devil Fruits (I’ve already mentioned how this is similar to Wapol’s Baku Baku no Mi, again I believe this Fruit is a specific aspect of this scientific process). Finally, the Devil Fruit will be eaten and will fuse/conjoin with a Soul and Body (I’ve already mentioned how Kanjuro’s Devil Fruit is similar to this phenomenon, I believe Kanjuro’s ability is to bind a type of Soul to his drawings and that’s why come to life. I think Kanjuro’s Fruit is an aspect of this scientific process.
Just to be clear, when I’m saying every Devil Fruit is a scientific process of scientific components, it’s true of what is scientifically possible in the world of One Piece. I think Vegapunk has some knowledge of the Devil Tree, that’s why Momonosuke can create clouds he can walk on and is a type of dragon, Vegapunk will have been able to replicate the process by using components of the clouds in a Sky Island with the biology of some kind of dragon.
Why Blackbeard can use more than 1 Fruit
I’m going to show a quote by Blackbeard which I think holds a deeper meaning than what’s shown on the surface:
Darkness is gravity! The power to pull everything in… and space not even a ray of light!… Infinite gravity!
We all know Blackbeard has a unique Logia in the Yami Yami no Mi. He can use his ‘infinite gravity’ to gravitate all living things/objects toward him. His darkness can suck all this in like a vortex where he can store them, and he can nullify all Devil Fruit users when touches them.
As you’ll know I already believe that for a Devil Fruit to work it has to be fused/conjoined to a Body and Soul, I also mentioned how Law couldn’t separate a Devil Fruit from a body, this is because the Soul must die first.
If we accept what I’ve said about Souls and how they scientifically work in One Piece, and we focus on the Blackbeard quote, ‘the power to pulleverything in… not even a ray of light!‘. I believe Blackbeard has the ability to suck in Souls! What?! Well, from a dead body. I also believe he can separate the three way relationship between the Body, Soul and Devil Fruit. Blackbeard can suck Devil Fruits toward him when he touches a Devil Fruit user, if he wasn’t touching the user he would be sucking the Body toward his darkness because, as I’ve said, he cannot separate Devil Fruit from an alive person as the Body and Fruit will be fused together. So what he can do is separate the Soul and Devil Fruit connection when he touches them, that is why their abilities are nullified. If a Fruit user is alive the Body and Soul won’t be separated, it works exactly like the Body and Devil Fruit connection. Even if Blackbeard could somehow suck in somebody’s Devil Fruit, he would die. Then, you may ask, how can Blackbeard use at least 2 Devil Fruits?
I’m now going to elaborate on how the Yami Yami no Mi works differently on someone who is alive and someone who is dead.
Now, if the person is dead, for example when Whitebeard died, Blackbeard would be able to suck in both Whitebeard’s Devil Fruit and Soul as they wouldn’t be fused together with the Body. Blackbeard would be able to store Whitebeard’s Soul and Gura Gura no Mi while attatching both to his body! That’s why Blackbeard doesn’t die, and that’s why it’s the most evil Devil Fruit. In this scenario Blackbeard would have 2 Souls for 2 Devil Fruits, but I believe he has 3 Souls!
This is obvious but I’ll say it anyway, Blackbeard is based on the real life pirate Blackbeard. What’s interesting though is that the real life pirate was known as Edward Teach, and also went by the name Thatch. The 2 people Blackbeard has killed are called Thatch, Edward Newgate, and of course Blackbeard himself is known as Marshall D. Teach. They all make up Blackbeard because Blackbeard has control over all 3 Souls!
I’ll end the theory by saying that no matter how many Souls Blackbeard can suck in I don’t think he can have more than 1 Devil Fruit from each class, meaning I believe Blackbeard will add a Zoan to attach to Thatch’s Soul. The Blackbeard Pirates are known to sneak in and take advantage of situations (like cowards!), such as at Impel Down and Marineford. Even Burgess attempted to take Luffy’s Gomu Gomu no Mi when he was exhausted against Doffy. So I believe Blackbeard will kill Monkey D. Dragon and steal his Devil Fruit or will sneak in once Luffy defeats Kaido, kill Kaido and take his Zoan.
