Brachio Tank 5-gou is a mechanized tank vehicle used by the Franky Family in One Piece. It is one of Franky’s “Battle Franky” support machines, designed for combat mobility and heavy firepower. The vehicle resembles a small armored tank and can be used in coordinated attacks alongside other Franky machines. As part of Franky’s arsenal, it reflects his engineering skill, flashy combat style, and the Straw Hat crew’s growing technological support during major battles.
