Kira Kira no Mi in One Piece

Jozu was sixteen years old when he ate the Kira Kira no Mi.

As the fruit hasn't yet been shown in the anime, we don't know a lot about its appearance.

This fruit allows the user to turn their body into a diamond. As a diamond is the hardest substance on earth, the user's defense was very enhanced. They are able to block almost any attack that comes in their way.

One weakness of this fruit is that when the user transforms into a diamond, their body seems to stiffen and they need to wait to transform into their original body in order to move properly.

They're also very susceptible to freezing even though they have immense toughness. They also have the standard devil fruit weakness: the inability to swim.

Jozu uses his devil fruit abilities to greatly increase his defense and offense. His attacks are already enhanced due to the density of his diamond body. He is also able to act as an effective barrier for long-range combat. When he uses Busoshoku Haki with his devil fruit powers on Logia Type users, it is more effective. He has yet to transform into a diamond.

The techniques used by Jozu are:

Brilliant Punk

In this technique, Jozu rushes toward his enemies at high speed and slams the person with his diamond-transformed forearm.
