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 Franky Shogun.
Fishman Island Arc
When the New Fishman Pirates' Hyper Toxin Squadron tried to poison Nico Robin, Franky drove the motorcycle out to run down the squadron, having immunity from the pricks and poison. A giant fishman tried to smash Franky and the bike with a giant flail, but was taken down by another new addition to the Soldier Dock, the Brachio Tank V. After both vehicles were caught in a pitfall made by Daruma, Franky took them both over, and "docked" them to form Iron Pirate Franky Shogun.
