Jozu is the 3rd fleet commander of the Whitebeard Pirates. He ate a Devil Fruit that allows him to change his body into diamonds.
Jozu is a supporting character from the anime/manga series One Piece, created by Eiichiro Oda. Jozu first appeared in One Piece Volume 25, CH. 234 "Please Be Sure to Remember it", and his first anime appearance was in One Piece - Episode 151 "100 Million Man! World's Greatest Power and Pirate Black Beard!". His character in the Japanese series is voiced by Takashi Nagasako.
Jozu is a very serious person, he doesn't talk too much but he still worries about his comrades. The only important change in the character was the supposed loss of his right arm as consequence of his battle with Aokiji in Marineford.
Jozu was among the men that resisted Shanks' "spirit" when he went on board of the Moby Dick to talk personally with Whitebeard about Ace and Blackbeard.
Jozu went to Marineford along with the rest of the Whitebeard Pirates and 46 New World's captains and their crews to rescue Ace. Jozu showed a great defence when he transformed part of his body into diamond to block the stab of the world's best swordsman, Mihawk, with no injuries. A few moments later Jozu made a notable demonstration of raw strenght by hurling a huge iceberg (which he got from the frozen sea water that Aokiji created with his "Ice Age") to the giants that were protecting the execution platform, unfortunately Akainu used the power of his Devil Fruit to destroy the iceberg a turn it into several volcanic rocks that damaged the nearby area. An interesting fact of this is that Jozu left a huge hole where Luffy and the Impel Down prisioners would fall into later.
In the course of the war, Jozu had other 2 important fights, in the first one he surprised Crocodile (who was getting rid of some pirates in the company of Daz Bones) and used his attack "Brilliant Punk" to hit him. Crocodile bled a little and quickly recovered but before Jozu could attack him by the second time, Doflamingo stopped him with his special ability to talk with Crocodile about a possible alliance between them. Crocodile refused to do that and created a sand tornado to get rid of both Jozu and Doflamingo. Time later, after the Whitebeard Pirates invaded Osiris Square, Jozu helped Whitebeard by hitting Aokiji when he was about to use his attack "Ice Block: Partisan" against the old man, Aokiji flied away and fell into pieces but he quickly regenerated with only a little bit of blood falling from his mouth as injury. Afterwards when the Kizaru's laser attacks went through Marco, Jozu got distracted and let Aokiji freeze his left arm, moments later Jozu is seen totally frozen and with his right arm almost cut into slices. Blenheim was the one who carried Jozu's frozen body in order to get him out of Marineford.
In the funeral of Ace and Whitebeard Jozu is seen again (covered with bandages) among the rest of the Whitebeard Pirates and their allies.
As one of the commanders on the Whitebeard pirate crew. Jozu has shown that he is a powerful member of the crew. He possesses great physical strength as well as incredible speed to compliment it. It is presumed that he can utilize Haki to some extent.
Jozu has an unnamed devil fruit power which allows him to turn his entire body, or just parts of his body into diamond. This gives him the nickname Diamond Jozu. With this devil fruit power, his durability is unsurpassed making him resistant to all types of physical attacks.
He also appears as a playable character in the videogame:
