What Is a Gomu Gomu No Red Hawk

Gomu Gomu no Red Hawk (ゴムゴムの火拳銃（レッドホーク） Gomu Gomu no Reddo Hōku, literally meaning "Rubber Rubber Fire Pistol")

A Haki enhanced version of Gomu Gomu no Jet Bullet. After entering Gear Second, Luffy uses Busoshoku Haki to harden his arm. He then stretches it back like Gomu Gomu no Bullet. Though 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. The Redhawk is a type of revolver, and the kanji name of this attack pays tribute to Ace's Hiken (火拳銃 means both "Fire Pistol" and "Fire Fist Gun"); the anime furthers this tribute by showing a flash of Ace when Luffy used this technique. This was first used against Hody Jones in his transformed state after the air bubble engulfed Noah.[17] In Funimation subs, this is called Gum-Gum Red Hawk, while in the Viz Manga it is called Gum-Gum Fire-Fist Pistol Red Hawk.
