Blackbeard has been accompanied by countless puzzles since his debut, and if nothing else, he should be the ultimate enemy of the protagonist Luffy. As a "foreshadowing demon", Oda Sensei naturally placed a lot of foreshadowing and details on the body of the new Fourth Emperor (Blackbeard).
As the plot of "One Piece" progresses, we also know the true fruit of Luffy, which turns out to be the human fruit esper species Nika form. At first glance, it seems to be talking about many foreshadowings on Luffy's body, but in addition to Luffy himself, it basically confirms some of The conjectures on Blackbeard.com. Why do I say that? Because "Nika" has a lot to do with "Blackbeard".
Nika has an antagonistic relationship with Blackbeard
Luffy's Nika fruit is a esper breed, and Nika herself is the "sun god" in the plot, combined with Luffy's relationship with Nika, it can be understood that Luffy is a new generation of "Nika". So what does Nika have to do with Blackbeard?
First of all, Nika is the "sun god", and Blackbeard is the representative of darkness in the plot, whether it is the way of life or the dark fruit held, the word "dark" is highlighted. And Nika, as the "sun god", just represents the light, and the light is against the darkness, that is, Luffy is the opposite of blackbeard. It shows that Nika and Blackbeard have an "opposite" setting.
Nika hates octopuses, which have three hearts
Based on the above information, it is further speculated that in Japanese legend, the creature that Nika hates is the "octopus", and the octopus happens to be the only creature in the biological world with "three hearts".
I believe that many people have heard the conjecture that Blackbeard has "three hearts", and many details and bridges in the plot allude to Blackbeard's relationship with the number "3". For example, the black group's pirate flag is three skulls, Blackbeard has three pistols pinned to his waist, three beards, etc., to say one or two details, it may be just a coincidence, but in Blackbeard's body so many times to see "3", people familiar with Oda Sensei will certainly not think it is a coincidence.
In general, it has always been rumored that Blackbeard has the conjecture of having "three hearts", and the moment Luffy determines that it is "Nika", it further increases the possibility of Blackbeard's "three hearts" conjecture. Luffy is the same as Nika, Nika hates octopus, Luffy hates Blackbeard, and octopus just happens to have "three hearts". Combined with the antagonistic relationship between Nika and Blackbeard mentioned above, is it that Oda implies that Blackbeard has "three hearts"?
Blackbeard Basic Hammer has "three hearts"
Many Hymi will think that the "three hearts" are a bit ridiculous, which is pure nonsense, but don't forget that Blackbeard's body is different from ordinary people. During the War at the Top, Marko mentioned that Blackbeard's body structure belongs to the "outlier", combined with Blackbeard's setting of never sleeping, the rationality of "three hearts" is further improved. The world of One Piece itself has unexplained phenomena, and now that Luffy has become an "immortal", it is understandable that Blackbeard has three hearts.
It is worth mentioning that as long as the octopus is placed together with Blackbeard, some interesting details will be discovered. For example, octopuses have strong memory ability in nature, and Blackbeard has been familiar with carrying the Devil Fruit Atlas many years ago; octopuss still let their tentacles move when they sleep, which is not a certain fit with Blackbeard's "never sleep"? Therefore, when Luffy confirms that it is Nika, Blackbeard's "three hearts" conjecture is nailed down!
