Wanze is CP7's melee fighting expert. He fights on roller skates, and can make ramen noodles by eating flour and using his nose hairs to cut it. Despite this, Sanji declares that Wanze is not fit to be a cook, due to Wanze being wasteful and disrespectful towards food. He is quite analytical, as he was able to figure out Sanji's weakness (in that immobilizing his legs makes him powerless) after fighting with him for only a few minutes. He fights Sanji with his "Ramen Kenpo" (noodle style), shooting ramen out of his nose and using them in various other ways, as well as using kitchen knives as darts and swords. At one point he uses this ramen to make a battle suit.
