A Blue Gorilla
by the Impel Down guards and prisoners, is a large masked gorilla-like beast with a skull painted on where its face should be. Blue Gorillas wield double-sided battle-axes and have incredible physical prowess, to the point of hunting Sea Kings for food. However, they are mindless creatures and are under the command of Saldeath, who controls them with a flute. They first appeared in Chapter 526 and Episode 423.
