#10 – Gomu Gomu no Pistol
This is Luffy’s signature attack; he stretches his arm back then throws a devastating punch. In other words, it is a standard straight punch, augmented with stretching. This attack can be used from short to long range. Luffy would typically increase the striking reach of fist by ‘charging up’ by means of first repeatedly swinging his un-stretched punching arm around before using the spinning force to both stretch his arm to its limits, and to maximize the hitting power
#9 – Gomu Gomu no Jet Pistol
Luffy delivers a Gomu Gomu no Pistol so fast that the fist’s movement is invisible, and it truly seems like he shoots his opponent, except that the resulting impact is not akin to an actual pistol, but to a small hand-held cannon and powerful enough to propel the unlucky recipient several meters away. The incredible speed both makes the strike far more powerful, and harder to dodge. This was first seen being used against Blueno.
#8 – Gomu Gomu no Jet Bazooka
Luffy charges at his opponent at high speed, and delivers an incredibly fast and strong Gomu Gomu no Bazooka. This was first seen being used against Blueno.
#7 – Gomu Gomu no Gigant Pistol
Luffy delivers a Gomu Gomu no Pistol with extreme force due to the larger size of his fist. This was first fully seen being used against Rob Lucci. Its sheer power was able to fling him from the Bridge of Hesitation on to a Buster Call Battleship.
#6 – Gomu Gomu no Kong Organ
The Gear Fourth version of Gomu Gomu no Gatling and rapid-fire version of Kong Gun. After compressing both fists into his arms, Luffy moves his arms horizontally in a rapid fashion before releasing a flurry of heavy punches. This was first used against Cracker’s Biscuit Soldiers, and each individual punch was powerful enough to smash through a biscuit shield.
#5 – Gomu Gomu no Cannonball (Gear Fourth Tankman: Full Version)
After trapping an enemy within him by compressing and withdrawing his stomach, Luffy launches them forward and into the air with incredible power and speed. This technique was first used to defeat Charlotte Cracker, who, when launched, plowed through several of his immensely hard Biscuit Soldiers and was sent flying far away.
#4 – Gomu Gomu no Leo Bazooka
The Gear Fourth version of Gomu Gomu no Bazooka. After retracting both of his fists into his arms, Luffy “fires” them at his opponent with a double open-palm strike. This was first used while airborne against Doflamingo, and its power sent him flying over Dressrosa and caused him to create an enormous crater when he slammed into the side of the King’s Plateau.
#3 – Gomu Gomu no King Kong Gun
The Gear Fourth version of Gomu Gomu no Gigant Pistol and Gomu Gomu no Elephant Gun, and one of the most powerful techniques Luffy has ever utilized in any form. After Luffy compresses his fist, like he does for Kong Gun, he blows a large amount of air into his arm, drastically increasing its size, then unleashes it for a devastating blow. This was first used to defeat Doflamingo, and was powerful enough to break through the Shichibukai’s Spider’s Web and God Thread techniques simultaneously, while still maintaining enough momentum to send him flying into the city below with enough force to completely level the town and cause the ground to fold in on itself.
#2 – Gomu Gomu no Red Hawk
After entering Gear Second, Luffy uses Busoshoku Haki to harden his arm entering in Gear Second Busō. He then stretches it back like Gomu Gomu no Bullet. When cocked back, his arm ignites, releasing a stream of fire. When the attack hits, it creates a fiery explosion even underwater and deals immense damage. This was first used against Hody Jones in his transformed state after the air bubble engulfed Noah.
#1 – Gomu Gomu no Jet Gatling
This is Luffy’s strongest technique in Gear Second. Luffy stands still, bends forward and moves his arms upwards at speeds which they can no longer be seen, leaving only jet streams in their place, very much like how the Jet Pistol looks. The hits land so fast that, after a volley, they seemingly connect simultaneously. The circles of air bursts from the punches surrounding Luffy, resemble the many barrels of an actual Gatling gun. This was first used to defeat Rob Lucci.
