Jozu as in Diamond Jozu, the commander of 3rd Division in WB's crew. He fought against Aokiji, Crocodile, defended against Mihawk's air slash, and threw a giant iceberg back then.

Oda revealed Jozu's DF is paramecia in the SBS but that's all we know so far. He did transform but most of the time, he can transform part of his body into diamond. Not sure why he doesn't transform fully into diamond.
