Franky

"Iron Man" Franky, the shipwright of the Straw Hat Pirates and one of the Senior Officers of the Straw Hat Grand Fleet, plays a crucial role in the crew. He holds the distinction of being the eighth member to join the Straw Hat Pirates, coming on board at the conclusion of the Post-Enies Lobby Arc. Originally named "Cutty Flam," he opted to adopt the moniker "Franky" at the behest of Iceburg, who encouraged him to conceal his true identity.

Franky hails from the South Blue and endured abandonment by his family when he was just four years old. His journey eventually led him to Water 7, where he became a valued member of Tom's Workers. Unfortunately, an unfortunate incident left his body severely damaged, necessitating extensive cybernetic enhancements. Upon returning to Water 7, Franky assumed the role of the leader of the Franky Family, a faction of ship dismantlers and bounty hunters. Initially, Franky and his followers were adversaries of the Straw Hats during the early stages of the Water 7 Arc. However, circumstances compelled them to forge an alliance by the end of the same arc and the Enies Lobby Arc. Franky's dream is to construct a ship capable of circumnavigating the world, and he realized this dream by building the Thousand Sunny and joining forces with the Straw Hat Pirates. Franky's bounty increased progressively over time, reaching 394,000,000 Beli after the Raid on Onigashima.

During the Egghead Arc, he underwent a change in attire, donning a full-body hooded jumpsuit with unique features and a distinctive headset. Franky is a human augmented with artificial components, commonly referred to as a cyborg. His frontal body is heavily armored and resistant to most forms of attack, while his vulnerable back remains exposed. He possesses an array of weaponry, including rockets, an extendable right arm, the ability to unleash powerful flames, and the capacity to release formidable air blasts from various body parts. His abdomen houses a refrigerator compartment capable of storing up to three cola bottles, which he uses both as a power source and for his attacks. Interestingly, his personality can be influenced by the type of beverage stored in his refrigerator. Franky's engineering prowess extends to the creation of a cannon-like mechanism that rapidly accumulates and releases compressed air-based projectiles, powerful enough to bring down large structures and serve as a means of propulsion. This innovation laid the foundation for his "Coup De Vent" capabilities. Franky designed the Thousand Sunny, imbuing it with unique features such as the Coup De Burst and the Soldier Dock System. Remarkably, Franky can complete complex construction tasks with incredible speed and precision. He once erected an entire bridge over a substantial gap, complete with intricate handrails, in record time. He even mastered the "Franky Skywalk," a technique involving the creation of mid-air suspended stairs, though their stability is temporary. This maneuver proved invaluable in his battle against Oars during the Thriller Bark Arc. Additionally, Franky's craftsmanship is highly regarded in Wano Country, where he went undercover as a carpenter and earned praise for his exceptional work. Franky demonstrated exceptional leadership skills when he led a group of Wano carpenters in the full restoration of damaged ships in preparation for the raid on Onigashima. With assistance from Usopp, he also single-handedly restored the Thousand Sunny to pristine condition overnight, despite extensive damage caused by Big Mom and later the Beasts Pirates.
