One Piece chapter 1145 , released on April 7th, reignited discussions by bringing back Rocks D. Xebec. Although still shrouded in mystery, his silhouette was revealed in a flashback with young Loki. This was enough to send fans of the series diving headfirst into wild theories.
But among the names frequently linked to Rocks, such as Gol D. Roger, Garp, and Blackbeard, an unlikely character began to be considered as a key piece of this web: Tony Tony Chopper, the lovable doctor of the Straw Hat Pirates.
Prepare to delve into one of the boldest theories in the One Piece universe, connecting the dark past of Rocks D. Xebec with the uncertain future of Chopper—and including the insatiable ambition of Marshall D. Teach, the dreaded Blackbeard.
Who was Rocks D. Xebec?
Rocks D. Xebec is a legendary figure in the One Piece universe. Captain of the feared Rocks Pirates, he commanded a crew that included names that would later become emperors of the seas, such as Kaido, Big Mom, and Whitebeard. His downfall during the God Valley Incident marked the end of the Rocks era, but did not erase him from history.
According to former Fleet Admiral Sengoku, Rocks violated many of the world's "taboos," raising suspicions that his exploits went far beyond ordinary piracy. Thus, this dark history fuels theories that he may have transformed into something more—possibly even a Devil Fruit.
"The Will of D" and its parallels with Drum Island
A point of intersection between Chopper, Blackbeard, and Rocks first appears in the Drum Island arc. It was there that the concept of the "Will of D" was first mentioned, through the eccentric Dr. Kureha. However, it was also in this arc that Blackbeard made his debut as an antagonist.
Chopper, a native of Drum Island, had direct contact with this enigmatic heritage. The connection between the "D." present in the names of Rocks and Teech, added to the shared geography with Chopper, gives rise to a surprising theory: what if the Straw Hat doctor unknowingly carries Rocks' legacy?
The Devil Fruit model: Rocks D. Xebec?
Chopper consumed the Hito Hito no Mi, a Zoan-type fruit that grants human intelligence to animals. Later, Oda introduced "model" versions of these fruits, such as the Hito Hito no Mi, Model: Daibutsu (consumed by Sengoku), and more recently, the Hito Hito no Mi, Model: Nika, which reveals Luffy's true identity.
What if Chopper's Devil Fruit is actually the Hito Hito no Mi, Model: Rocks D. Xebec? This would explain why Blackbeard would be interested in the little renose. As a possible heir to Rocks' powers or essence, Chopper could become a key piece for Teech to claim the legacy of the infamous captain of the Rocks Pirates—or even absorb his power, if it's possible to "steal" this type of fruit.
Blackbeard, the son of Rocks?
Another popular theory claims that Marshall D. Teech is the biological or ideological son of Rocks D. Xebec. This is reinforced by the name of his ship, Saber of Xebec, a direct homage to the former captain. Thus, if this connection is real, Teech's interest in Chopper would gain new layers: in addition to power, there would be a personal component, perhaps even a sense of inheritance or revenge.
Bold theory or legitimate clue?
Although there is no official confirmation from Eiichiro Oda, the theory linking Chopper to Rocks and Blackbeard is based on well-placed details in the One Piece lore. The combination of the "Will of D," the mystery of the Model Devil Fruits, and Blackbeard's presence on Drum Island builds a plausible—and exciting—storyline.
For fans, the beauty of One Piece lies precisely in its ability to connect seemingly disparate pieces of a gigantic puzzle. And if this theory is confirmed, Chopper would cease to be just the crew's mascot and become one of the most crucial figures in the fate of the world.
