Strong Right is one of Franky's signature moves in the series One Piece, where he showcases his bizarre combination of cyborg enhancements and fighting skills. The move is a part of Franky's BF-36 weaponry, a series of body modifications made by himself. Using this technique, Franky aims at the opponent with his right arm and then discharges his chained right fist at high speed toward the target.
Strong Right showed the ingenuity that Franky had toward self-improvement. His right arm had been designed internally with a mechanism of chain links that allowed the fist to detach and extend, effectively turning the arm into a long-range weapon. This gave Franky a means of hitting enemies from afar without having to do so face-to-face, which gave versatility to his close-range attacks.
Most of Franky's techniques, including Strong Right, are powered by cola, which serves as the energy source for his cyborg functions. This weird power system is one of the characteristics identifying Franky's fight style and makes it more strategic in his battles. Franky has to be very careful with the amount of cola he drinks, since techniques like Strong Right put pressure on his energy.
This was notably reflected in the anime and manga, with the visual fighting action that Strong Right symbolized. Common expression of the technique in action: Franky detaches his right fist from his arm with a mechanical burst of energy, connected by a sturdy chain. The speed and force of the attack are commonplace and usually depicted by a more dynamic animation and sound effects, which denote its effect.
Franky has been developing and improving the Strong Right throughout the series. He added a new version of this technique to his BF-37 upgrades. This new upgraded version features a far more enormous right fist than in the original attack, increasing its power and reach. In this evolution, Franky moves much further ahead, showing his never-ending interest in personal development and being able to adapt to more and greater challenges that lie ahead for the Straw Hat Pirates.
Indeed, Strong Right has been quite prominent in a number of key fights the Straw Hats have been in throughout the series. Its versatility makes it useful for a variety of combat situations, be it by smashing an enemy at a distance or grating at them up close, or a switcheroo with an enemy or object. For example, Franky has used the Strong Right to bust through walls, grab ledges for crazy mobility, even as a surprise attack at unsuspecting foes.
The name of the technique, "Strong Right," is a play on words that reflects Franky's personality and the nature of the attack. What is combined is the English word "strong" with "right," indicating both the power of the technique and the arm used to execute it. This naming convention is characteristic of Franky's flamboyance and use of English words in his attack names.
Strong Right does more than serve as another fighting trick for Franky; it actually is representative of his character development. As the crew's shipwright, he has applied these extrapolated potentials of constant touching-up and remodeling to his own body; they also reveal his inherent talents for ship maintenance and overhaul operations, which he carries out on the crew's ship, the Thousand Sunny. In parallel, Strong Right is representative not of his fighting style, but his major philosophy in the constant change and ways of adapting in the Grand Line necessary for survival.
This popularity enjoyed by the Strong Right in the eyes of fans resulted in its presence in various One Piece video games and other media. More often than not, this technique ends up being operable through Franky when one gets to be in control of him, thus giving a feel at this attack firsthand—strong and versatile. This addition in interactive media cements the strong status of Strong Right as one of the iconic moves of Franky.
