Instructor-Zephyr

Zephyr is a large, muscular, tan-skinned man, standing around twice the height of a typical man such as Luffy, with short purple hair and a large mechanical right arm connected to the left hip with converted mast rigging. Underneath that mechanical arm is a regular-sized and pitch black prosthetic arm. He dressed in a Marine-like coat with his Jolly Roger impressed on it, baggy trousers tucked into his boots, and a pair of triangular sunglasses.
