Zambai

Zambai (ザンバイ, Zanbai) is Franky's right hand man who leads the Franky Family when Franky is not around.
In terms of fighting ability, Zambai seems more competent than most members of the Franky Family in both melee and long range, armed with a bazooka and a pair of katanas, he was able to fight toe-to-toe against Baskerville (all three) before he, Galley-La and the rest of the Family was captured by the Marines.

First Appearance: Chapter 324; Episode 230
