One Piece delves deeper into the past of Rocks D. Xebec , a legendary character who has intrigued fans since his first mention in chapter 907. Now, with chapter 1154, Eiichiro Oda officially introduces Xebec, and there's no doubt that the mangaka will explore even more about 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, it's necessary to 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 mastering Haki. 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 so feared?
The most likely answer is clear: Rocks D. Xebec possessed a Devil Fruit powerful enough to balance the difference in Haki with Roger . This would explain why Sengoku ranked him as Roger's greatest rival—even though Roger had 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 ever stronger than Roger, even with inferior Haki, his extra strength may have come from an extremely powerful Devil Fruit. However, it's possibly one that 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 that revelation for the right moment.
Oda prepares the ground for the final stretch
As Oda himself said in 2022, he is ready to reveal the biggest secrets of the One Piece world. Rocks' appearance is another step in that direction. Readers are now eagerly awaiting chapter 1156, which will be officially released on August 3, 2025 , on the Manga Plus website.
