Franky/Abilities and Powers

Abilities and Powers
As a member of the Straw Hat Pirates, Franky is a competent crewmate as well as a valuable asset for the crew. And 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. In terms of raw physical power, Franky could easily be counted as among the stronger members of the crew, surpassed only by the Monster Trio. His years of being a ship dismantler as well as bounty hunter prior to Piracy seem to have contributed greatly to his formidable strength; even when running low on cola, he exhibits enough strength to overwhelm a charging, fully grown elephant-stopping it in its tracks before dragging it around by the trunk like it was a rag doll. In addition to his strength, Franky also displays considerable skill on whatever item he lays his hands upon, be it in or out of combat (i.e. he was seen wielding with considerable dexterity a large pair of makeshift nun-chakus effectively against Talleran). And even without his cyborg functions, Franky's fighting abilities are more than enough to allow him to fight even against trained assassins. The fact that he could defeat Fukurou, a member of CP9 on his own is a testament to his prowess. His fighting style appears to revolve around boxing, but he does not hesitate to fight dirty if need be.

Cyborg Body
Franky is a human with artificial parts; commonly known as a cyborg. These modifications grant him a vast amount of strength, so much in fact that he was able to successfully overpower CP9 Members Nero and Fukurou. His back however is still wholly flesh and blood and is therefore one of his greatest weaknesses; Franky did the modifications himself, and could not reach his back. Even without modifications, his back is dense enough to endure multiple pistol shots or a Rankyaku from an experienced Rokushiki user. Additionally, despite having most of his anatomy reinforced with solid steel, Franky has somehow made it possible for his cyborg body to retain its buoyant properties, allowing him to stay afloat on the surface of deep water, which would otherwise be impossible since anything comprised of metal would normally just as easily sink as a Devil Fruit user would in the sea. It would seem that Franky is also an excellent swimmer, even before becoming the cyborg he is now. A fact made apparent by his ability to outswim the sea kings that he frequently tries to slay with his series of battle Franky's during his childhood. Using his Franky Butterfly, he can swim upstream in the waterfalls of Enies Lobby.

Franky's left arm is primarily used as a gun; a multi-barreled machine gun can pop out of his wrist, any of his fingers can fire bullets, and by turning aside his hand, Franky can reveal a cannon in his arm that uses his left hand as a targeting device. Franky's right hand is an iron fist beneath a more normal-looking cover, and the hand has an extendable chain that allows him to make attacks from a distance.

Some common attacks include Strong Right: Franky launches his right fist forward and can reel it back in with a chain, similar to Luffy's Gomu Gomu no Pistol; and Coup de Vent: Franky connects his arms with a T-shaped pipe and sends a powerful blast of concentrated air out that can destroy entire building complexes. Coup de Vent is his most powerful attack which incidentally uses up the most cola. Franky also has the power to turn into a centaur-like form with an extra set of legs strangely extending forward from his pelvis, though he has implied that its use is limited by stating he is "super powerful this week" just before he uses it. Despite his pride in it, it seems to do relatively little for any of his combat abilities, save for using his four legs to trap his enemy's limbs, leaving them completely at the mercy of his attacks.

It was shown during Franky's fight with Fukurou that depending on what kind of drink Franky has, it can change his hair style and attitude when Chopper accidentally hands him vegetable juice and tea. It also shows that Franky's strength is many times greater when he has more bottles of cola in his stomach fridge, and he needs it as a fuel for certain attacks. His hair acts as a kind of meter to the amount of cola in his stomach being tall if he is full and sagging if empty. Franky's stomach compartment can hold up to three bottles, or six liters, of cola.

After two years, Franky has drastically modified his body and became much larger and optimal in appearance and function, respectively, the most major non-aesthetic change being the metalization of his once exposed and still normal back. With that final step Franky is now entirely a cyborg, and has removed his biggest vulnerability. The true potential and abilities of his new BF-37 model have yet to be showcased, however, but it can be inferred that he is on the absolute cutting edge technology-wise, since nearly all of the futuristic and technological aspects of the Marines and the world as a whole (i.e. the Pacifistas and the assimilation of Devil Fruits into weapons) stem from Dr. Vegapunks genius, and it was using his laboratory, notes and research that Franky upgraded himself. It is also worth noting that Franky's original transformation into BF-36 was initiated as a quasi-surgical operation of necessity to save his life, and it is assumed was accomplished with some modicum of haste from a medical standpoint, since he suffered from massive external and internal injuries; Whereas the process to become BF-37 was a two year long planned process done with highly advanced machinery in a fully-stocked, albeit abandoned, scientific laboratory, on his preexisting cyborg body, so Franky's own experience being one beforehand was likely factored in when customizing its schematics and functions, as well as understanding whatever information Vegapunk left behind. Franky even went the extra-mile with his modifications, adding utility functions like his 'Franky Nipple Lights', and nonsense functions like his pop-up hair feature. With all this in mind, post-timeskip Franky is truly a force to be reckoned with.

Weapons
Though Franky is seldom seen carrying weapons (owing to the fact that he stores them on-board his person) he is has been known to wield tools and implements from time to time, most notably his carpentry tools, though at other times, he is seen carrying conventional weapons that he seems to be able to wield proficiently. Such weapons include custom-built nunchakus, handheld cannons, etc.

Construction and Engineering Expertise
In addition to his cyborg-enhanced body, Franky is also a first-rate shipwright and carpenter from working under Tom. Even his years of dismantling had not affected his carpentry skills in any way; perhaps the best proof of this was when he was able to finish the construction of the Thousand Sunny, with the aid of Iceburg and the remaining Galley-La foreman, under a short period of time. A genius of his own right, he developed a cannon-like mechanism that accumulates air rapidly within a confined space right before releasing it as a compressed air-based projectile powerful enough to bring down large establishments as well as provide a superb means of propulsion, which served as a template that gave birth to the creation of his Coup De Vent functions. He designed the Thousand Sunny himself featuring several unique functions like the Coup De Burst and Soldier Dock System, and has actually built an entire bridge over a large gap and even put in small details such as carved handrails in an extraordinarily small amount of time (though he wanted an extra thirty seconds since he wasn't satisfied with the finish). He can also somehow build stairs suspended in midair, and while they can support human weight, they do not stand for long. He calls this maneuver "Franky Skywalk," and was used fighting Oars in the Thriller Bark arc. He also quickly sealed Caribou in a barrel and made it so even with his devil fruit power he couldn't escape.
