Fifth Gear: Nika Form	11	Declared as his ultimate power during his battle with Shanks at Elbaf.

Appearance

Luffy is identified by the Straw Hat entrusted to him by Shanks. In Gear Fourth, his black hair rises and his body is marked by dark-purple Armament Haki patterns; in Nika Form, white coloration spreads across his clothing and hair while white, flame-like clouds circle his shoulders. 12 272 11

• Wears Shanks's Straw Hat as a symbol of their promise. 12
• Emits white steam and turns red while using Gear Second. 63
• Expands his Haki-hardened body in Gear Fourth: Bounce-Man. 272
• Takes on white hair accents and streamer-like clouds in Fifth Gear: Nika Form. 11

Personality

Luffy is carefree, impulsive, and driven by whatever he feels is right. He is often unconcerned with status, background, or danger: he does not know what a navigator is when first told the crew needs one, and he dismisses the importance of his father's position as Revolutionary Army leader. 15 146

His simplicity is paired with fierce loyalty. He treats crewmates as unquestionable nakama, accepts Robin despite her past, and refuses to abandon those being threatened or oppressed. 74 110 He also rejects positions that would compromise his freedom, turning down Kuma's Shichibukai invitation because his goal is to become Pirate King rather than anyone's subordinate. 168

Abilities & Skills

Gum-Gum Physiology

Luffy is a rubber man who ate the Gum-Gum Fruit, granting him an elastic body and the foundation for his self-developed combat forms. 14

• Can stretch, inflate, compress, and propel his body for unconventional attacks and movement.
• His rubber body lets him safely use Gear Second's accelerated blood flow, though the strain remains severe. 63
• When his powers were sealed, he still forced himself into Gear Second by precisely accelerating his circulation, suffering painful backlash. 400

Gear Second

Gear Second turns Luffy's body red and produces white steam as it accelerates his blood flow. 63

• Greatly increases close-range speed, enough to overwhelm Enel despite Enel's Observation Haki. 103
• Supports techniques such as Gum-Gum Jet Pistol, Jet Stamp, and Gum-Gum Gatling. 103 135
• Initially causes exhaustion after use and can shorten his lifespan if used too frequently. 62 63

Gear Fourth

Gear Fourth uses inflated muscles reinforced with Armament Haki to produce a major increase in force and mobility. 272

• Bounce-Man — Uses compressed, Haki-hardened muscle inflation for powerful attacks such as Gomu Gomu no Elephant Gun and King Kong Gun. 273 313
• Snake Man — Emphasizes speed and rapid attacks, including Gomu Gomu no Black Mamba. 288
• Maintaining the form consumes enormous amounts of Haki and temporarily prevents him from using Haki after it ends. 273

Fifth Gear: Nika Form

Luffy calls Fifth Gear: Nika Form his ultimate power. 11

• Activated against Shanks after he is pressed to reveal his full strength. 11
• Alters his appearance with white hair accents and cloud-like white streamers around his shoulders. 11

Haki

Luffy uses all three major forms of Haki in combat.

• Observation Haki — Predicts Zephyr's movements and evades a counterattack before it lands. 272
• Armament Haki — Coats his body and attacks in hardened Haki, including his Fire Fist Pistol and Gear Fourth forms. 272
• Conqueror's Haki — Clashes with Garp alongside Lina and Ace, causing massive destruction in Impel Down; later knocks out spectators during the battle for the Tremor-Tremor Fruit. 200 305

Ice Powers

Luffy has demonstrated ice-based abilities in battle, including an Ice Age that freezes the battlefield. Aokiji countered it with an Ice Age of his own. 393

Equipment

• Straw Hat — Shanks's most precious possession, lent to Luffy when he was seven. Luffy promised to return it only after surpassing Shanks. 12
• Going Merry — The Straw Hat Pirates' ship, used throughout their voyage and retained after its Water 7 renovation. 20 149
