Jozu

ジョズ

Jozu commands the 3rd division of the Whitebeard Pirates.
First Appearance: Chapter 234; Episode 151
As the 3rd division commander of the Whitebeard Pirates, Jozu holds authority over lower-ranking subordinates. He was among the few individuals unaffected by the potent Haki emitted by the Yonkou Shanks. He is highly experienced and a veteran of the Whitebeard Pirates dating back to the era of Gol D. Roger.
Jozu ranks as one of the strongest members of the Whitebeard Pirates, evidenced by his role as 3rd division commander. During the Marineford War, Jozu possessed sufficient power to fight on equal footing against the Shichibukai and the Marine Admirals.
Jozu possesses exceptional brute strength, comparable to that of the Giant Squad Marines. He lifted and hurled a massive iceberg over a great distance at the giants guarding Marineford. The iceberg was so colossal that it appeared to be at least ten times larger than any of the giants. Consequently, Jozu has demonstrated one of the most significant strength feats in the series. Furthermore, despite his massive physique, his speed and reflexes match his brute force; when he attacked Crocodile after the latter attempted to kill Whitebeard, Crocodile remarked on both the immense speed and strength of the assault.
Jozu has consumed a currently unnamed Devil Fruit that enables him to transform parts, and most likely all, of his body into diamond. This ability has earned him the nickname "Diamond Jozu". It remains unknown whether this is a Paramecia-type fruit, similar to the Supa Supa no Mi.
Jozu's powers allow him to significantly boost his offensive and defensive capabilities. His already powerful physical attacks are amplified by the density of his diamond body. His defenses appear to increase exponentially, enabling him to block the world's strongest slash from the world's greatest swordsman, Shichibukai Juracule Mihawk, without sustaining visible damage. However, when his entire body is not in full diamond form, he remains vulnerable to Aokiji's freezing abilities. Aside from this, Jozu is susceptible to standard Devil Fruit weaknesses.
