In the War on the Top, Blackbeard, who originally possessed the Dark Fruit, took the opportunity to kill Whitebeard and rob Whitebeard of the Shock Fruit.
A person can possess two Demon Fruits at the same time, the first ever, so Blackbeard's presence became the greatest threat above the sea.
Blackbeard claims that dark fruit can devour everything, so many people believe that Blackbeard can plunder a variety of demon fruits through dark fruit.
But this is not entirely true, otherwise why would Blackbeard give the Invisibility Fruit to Hiryu, and why would he give the Burnt Fruit to the Fighting Champion. Blackbeard is not a person who is good at sharing, so it can only mean that he can bear a limited number of demon fruits, and although the dark fruits can swallow everything, they cannot swallow the demon fruits.
So how did Blackbeard take Whitebeard's Demon Fruit, and how much of it he was able to devour?
The rebirth of the Devil Fruit
Demon Fruit has the ability to be reborn, and after the owner dies, the Demon Fruit transforms into a fruit near it.
After the death of the Pangdao Salamander, its demonic fruit abilities were transformed on a nearby apple, and why the burned fruit fell into the hands of Mingo, how Blackbeard got the Invisibility Fruit, and Whitebeard's Shock Fruit, all of which were reborn after the owner died.
Blackbeard's conjecture of plundering the Devil's Fruit
When Blackbeard seized the Whitebeard Demon Fruit, he covered it with a black cloth, and then the black cloth was unveiled, and Whitebeard did not look out, but Blackbeard announced that he had captured the Shock Fruit.
When the Dark Fruit works, the capable person's hands will turn black, the body will emit black smoke, and it can swallow everything related to darkness. Blackbeard may have covered it with a black cloth so as not to hurt anyone else, but why Whitebeard was not swallowed by him, according to this, the Dark Fruit can devour the Demon Fruit, and it needs to be a question mark.
Did Blackbeard use other means to seize Whitebeard's Demon Fruit, was it some kind of superpower, or was it because of the structure of the body? In the War on top, Marko once said that Blackbeard's body structure is different from ordinary people, and what kind of structure is unknown.
Blackbeard kills Thatch and leaves the Whitebeard Pirates to form the Blackbeard Pirates and comes to magnetic drum country. Why did Blackbeard come to Magnetic Drum Country? Magnetic Drum Country is a medically developed island country, Blackbeard came here, mostly because of abnormal body structure, or to transform the body.
Blackbeard seized the Shock Fruit because of his body structure, not because of the Dark Fruit, the unusual body allowed him to have two or more Demon Fruits, and he granted the Invisibility Fruit and the Burnt Fruit to others, indicating that he had a limited number of Demon Fruits.
Blackbeard can devour the number of demon fruits
Blackbeard has already eaten two demon fruits, is the number has been capped, after all, ordinary people can not have two kinds of demon fruits at a time, blackbeard who can have two kinds of demon fruits is already invincible.
Will Blackbeard have the ability to devour multiple demon fruits?
Blackbeard meets Luffy Sauron and Nami in the Magnetic Drum Country, and the conversation between the three of them when they leave is also very meaningful, and Luffy Sauron also says that it is not that person, but those people. Nami asked incredulously, obviously a person, why do you say those people? Blackbeard is a man, where do those people come from?
Presumably Luffy Sauron saw Blackbeard's body structure, and how many of those people were there? Two people are not called "those", so "those" are probably "3" or more, but most likely "3", why do you say that?
There are two aspects that can be proved, one is: the flag of the Blackbeard Pirate Regiment, the flag of the pirate corresponds to the characteristics of the captain, Luffy wears a straw hat, so the flag has a straw hat on it, the flag of Whitebeard has a white beard on it, and the flag of Blackbeard is above three skulls linked together, which is very much like a Siamese.
In medicine, there have been many conjoined people with two people connected together, they either share a heart or a body, and there are two organs in the body, or the external connection of the body. Among the various Conjoined people, only those who have two complete organs have the possibility of surviving.
There are about three people in Blackbeard's body, and they all have their own complete organs, but in what way they coexist, it is impossible to guess, it will not be shadows, nor will they be souls, their existence is a living body.
Two: Blackbeard has two younger sisters, but has not yet been missing, Blackbeard's prototype is the historical Sea Thief Edward. Titch, he is a family pirate, so the Blackbeard Pirates will also be a family pirate group.
That is to say, Blackbeard's two sisters are also among them, but they have never appeared, and it is very likely that they are in Blackbeard's body, and the three of them coexist in one body. Conjoined people survive because they have independent hearts, even independent organs, and the three Blackbeard brothers and sisters, in order to achieve their own goals, through some kind of surgery, the three people are integrated into one, and this operation will have side effects.
After the battle between Roger's Pirates and Whitebeard's Pirates, interns Shanks and Bucky both discover that Blackbeard never sleeps, and Marko has said that Blackbeard lives twice as long as others, which may be a side effect.
This is why Blackbeard uses a black cloth when plundering the shock fruit, so as not to expose the special body structure to others, so he covers it with a black cloth.
Blackbeard memorized the Demon Fruit by heart, so they were very clear about the Demon Fruit they wanted to plunder. First of all, it is the strongest natural dark fruit, followed by the strongest superhuman system earthquake fruit, and finally it will probably be the animal line of the strongest creature Kaido, the fish and fish fruit.
In summary, the Dark Fruit can devour everything but not the Demon Fruit, Blackbeard's body structure is his method of capturing the Shock Fruit, Kaido and Luffy's battle is nearing the end, if Blackbeard will appear on the Ghost Island, then the above speculation will be confirmed.
If so, then Kaido will have the same ending as Whitebeard, who will become Luffy's ultimate boss on his way to One Piece.
