Design[]
It is a giant black motorcycle with three wheels and the armored head of a rhino. It is very powerful, and capable of barreling through multiple enemies. It has the trademark star on the two back wheels. It is made of Wapometal and can "dock" with the Brachio Tank V to form the Iron Pirate General Franky.
