As a member of the Straw Hat Pirates, Franky is a competent crewmate as well as a valuable asset for the crew. Being their official shipwright, Franky is in charge of maintaining the Thousand Sunny's condition, along with the other vehicles, instruments, or weapons that the Straw Hats may employ. He is also an accomplished surgeon as he was able to perform an operation on himself twice, despite the fact that he does not specialize in the field. He was able to do this even though he was close to death.
