Few of the characters in One Piece are as evil as Marshall D. Teach, better known as Blackbeard. Initially a member of Whitebeard’s crew, Teach betrayed his surrogate father and siblings when he killed Thatch to steal the great Yami Yami no Mi. As if that wasn’t enough, Blackbeard captured Portgas D. Ace and handed him over to the World Government to earn warlord status. All this in order to provoke a war that will allow him to gain the crew he wants, kill Whitebeard and steal the powers of the Devil Fruit.
Oddly enough, Blackbeard is the first human in One Piece history to be able to use two Devil Fruit powers simultaneously, which is said to be an impossible feat. Agent CP-9 Jabra himself reveals that he is proving that this limitation was not an elaborate plot of the World Government. In addition, Marines and pirates were shocked to see Teach wielding two different powers. But how can he do this? Below is a dive into the most popular theories.
Cerberus Theory – Blackbeard ate a Devil Fruit before
The Cerberus theory, one of the most popular ideas in the One Piece community, posits that Blackbeard had already eaten a Devil Fruit before eating Yami Yami no Mi. Specifically, the legendary Xuan fruit is probably called Inu. Inu no Mi, Cerberus Form. Theorists believe that due to the actual mythical nature of Cerberus, which has three independently minded heads, it allows Teach to use more than one Devil Fruit. The rationale for this theory comes mainly from the way Blackbeard and his actions tend to revolve around the number three.
First of all, Jolly Roger of Blackbeard is supposed to represent the captain of the ship. Its specific flag includes the usual skull, but also, curiously, three skulls very close together, like that of Cerberus. Then there’s his weapon of choice, a three-bladed claw he’s been using since joining the Whitebeard Pirates. This claw is actually the origin of Shanks’ famous scar on his left eye, or it could be a hypothetical blackbeard’s zwan shape claw. The fact that the legend of Cerberus exists directly in the universe of One Piece gives this theory even more credibility.
Chimera Theory – There are multiple entities inside Blackbeard
Like Cerberus’ theory, Chimera’s theory is based on the idea that Blackbeard had several entities. While the former suggests that it originated from eating a devil fruit, the Chimera theory asserts that this is how Blackbeard was born. Since Marco the Phoenix said during Marineford that Blackbeard’s body is unique, there is some evidence included in One Piece to support this theory.
Although this is rare, there are many cases where fetuses absorb each other in the womb before they are even born. This is commonly referred to as the “vanishing twin”. This process essentially creates a person with many DNA and combinations of genes, which can lead to abnormalities in the body after birth. The same fetus can give rise to multiple organ groups.
It’s entirely possible that Blackbeard’s body contains multiple “objects”, which is why having so many Devil Fruits doesn’t kill him. If a person could only obtain one Devil Fruit and the Blackbeard was actually made up of several people, it was entirely possible that their body would use as many Devil Fruits as possible.
Yami Yami No Myth – Disable Devil Fruit User Powers
The One Piece theory is unique in that it deviates almost completely from the idea that Blackbeard’s body is responsible for his ability to use the multiple powers of the Devil Fruit. This ability comes from Yami Yami no Mi instead, which is why he was willing to kill Touch to get it. The Yami Yami no Myth legend also confirms the idea that Blackbeard’s Devil Fruit is as special as it claims.
Since his fight against Ace, Blackbeard has stated that Yami Yami no Mi is unique among Devil Fruits, especially Logias. While it doesn’t offer him the same intangibles that Loggias is famous for – and actually make him more susceptible to damage than he would be without him – Blackbeard has made it clear that his other abilities more than make up for it. Thus, his mastery of darkness has given him some control over gravity, allowing him to bring things and people closer to him against their will. He is even able to absorb things in his darkness and then expel them with great force.
However, his greatest strength was his unique ability to quell the powers of a Devil Fruit user, which Blackbeard first demonstrated against Ace. Many fans believe that it was this power, or an extension of it, that allowed Teach to seize Blackbeard’s Devil Fruit abilities. If that was the case, this could easily explain why he was so keen on obtaining this particular demon fruit, since he had even admitted to waiting for decades on the Whitebeard Ship in hopes of obtaining it.
Vegapunk Effect – Blackbeard’s body has been improved
Perhaps the most unusual theory is the Vegapunk effect, which came up with the idea that Vegapunk upgraded Teach’s body so he could use multiple demon fruits. This theory is considered one of the least likely, as it requires many different details to prove its validity. In particular, the infamous Dr. Vegapunk, who has worked with the World Government for years, had to meet Blackbeard sometime before the events of One Piece.
Given so little is known about Dr. Vejapunk, it is difficult to deny the validity of this theory or to accept it. After the Straw Hats split on Sappodi, Frankie lands on Karakuri Island, a winter island on the Grand Line where Vijapunk grew up. It has been confirmed that Blackbeard was also born on an island in the Grand Line, although the exact location has yet to be revealed. If any experiments were carried out, it is likely that it took place on the island of Karakuri, but without knowing the origin of Blackbeard, it is impossible to be sure. While it is possible that these experiments occurred after Teach joined the Blackbeard Pirates, it is unlikely that the World Government was aware of the threat it posed.
There are many possible explanations for how Blackbeard used a devil fruit in One Piece. In fact, if he could use two, there’s no reason to believe he couldn’t use three, especially given the character’s – and the show as a whole – obsession with the number three. Blackbeard uses up to three pistols and has three missing teeth. Whether the real reason is good or bad, one thing is for sure: One Piece loves to take her time to make it happen.
