1 GOMU GOMU NO MI
The Gomu Gomu no Mi is a Paramecia-type Devil Fruit that gives the user’s body the properties of rubber, making the user a Rubber Human. It was accidentally eaten by Monkey D. Luffy.
Having undergone intense training for over ten years, Luffy is now able to supplement his stretching powers with immense strength, agility, and creativity in combat.
Luffy developed several peculiar methods of combat as time passed, adapting new forms by manipulating his elastic body, most prominent his “Gear Second” and “Gear Third” forms, allowing him to momentarily increase his strength in combat. After the timeskip, he has learned to use Haki in conjunction with the fruit’s powers, as well as having more control over his forms. Later, during the time skip, Luffy developed a form known as Gear Fourth.
