One Piece delves deeper into the past of Rocks D. Xebec , a legendary character who has captivated fans since his first mention in chapter 907. Now, with chapter 1154, Eiichiro Oda officially introduces us to Xebec, and there's no doubt that the mangaka will explore even more of his strength and mysteries. Among the major revelations, one detail stands out: Oda has already hinted that Xebec was a Devil Fruit user .
The rivalry between Rocks and Roger in One Piece

To understand Rocks D. Xebec's power level, we must analyze his relationship with Gol D. Roger. According to Kaido, "only Haki conquers all." This statement indicates that, despite the strength a Devil Fruit can grant, the true difference lies in Haki mastery. And, in Kaido's view, Roger was the greatest Haki user of all time—surpassing even Rocks, Shiki, and Whitebeard himself.
If Roger had more Haki… what made Rocks feared?
The most likely answer is clear: Rocks D. Xebec possessed a Devil Fruit powerful enough to balance out Roger's Haki difference . This would explain why Sengoku ranked him as Roger's greatest rival—even though Roger possessed superior Haki. The same reasoning applies to Whitebeard, who rivaled Roger thanks to the power of the Gura Gura no Mi.
Therefore, if Rocks was, at some point, stronger than Roger, despite having inferior Haki, his extra strength may have come from an extremely powerful fruit. However, it could even be one fans already know, such as the Yami Yami no Mi , the Ope Ope no Mi , or the Mera Mera no Mi. However, it's equally possible that Oda created a new fruit, saving this revelation for the right moment.
Oda sets the stage for the final stretch
As Oda himself stated in 2022, he's ready to reveal the greatest secrets of the One Piece world. Rocks' appearance is another step in that direction. Readers now eagerly await Chapter 1156, which will officially release on August 3, 2025 , on the Manga Plus website.
