Luffy Gomu Gomu no Mi

The Gomu Gomu no Mi is a Paramecia-type Devil Fruit that enables the user's body to stretch like rubber, making the user a Rubber Human . "Gomu" means rubber in Japanese. In the Viz Manga, 4Kids and FUNimation dubs, it is called the Gum-Gum Fruit. It was originally a treasure that Shanks and his crew took from an unspecified enemy, but was accidentally eaten by the series protagonist Monkey D. Luffy. In the second version of Romance Dawn, it originally belonged to Luffy's grandpa who took it from an unspecified enemy.
The Gomu Gomu no Mi is a violet, spherical shaped fruit with a stem sprouting out of the top, with swirls that go in a curly "S" like-pattern. Its overall appearance greatly resembles a Yubari King.The fruit's major strength, as demonstrated by Luffy, is that the person's body can stretch like rubber even when the ability user himself is nullified . It also makes them almost entirely immune to blunt attacks, including hand-to-hand combat, bullets or even cannonballs, an ability which can be further reinforced with the application of Busoshoku Haki.
