Why Is Luffy Made of Rubber? (2026) — Gomu Gomu No Mi Explained

Devil Fruits — The Power System

Devil Fruits are mysterious fruits found across the world of One Piece. Eating one grants a unique supernatural ability but permanently removes the user's ability to swim — a significant weakness in a world dominated by the ocean. Each fruit grants a different power, and each power can only exist in one person at a time.

Paramecia Type — Body Modification

The Gomu Gomu no Mi is a Paramecia-type Devil Fruit — one of three types. Paramecia fruits give the user a superhuman body ability, generate a substance, or manipulate their environment. Gomu Gomu transforms the user's entire body into rubber — including internal organs, bones, and skin — making them immune to blunt impact and electricity while allowing stretching.

The Shocking Truth (Manga Spoiler)

In the manga, it is revealed that the Gomu Gomu no Mi is not actually its real name. The fruit is actually the Hito Hito no Mi, Model: Nika — the Mythical Zoan fruit of the Sun God Nika, a legendary figure who freed slaves through laughter and whose abilities are described as giving its user a body with the properties of rubber and the ability to make anything possible with imagination. The World Government had been hunting this specific fruit for 800 years. Luffy eating it was not an accident — the fruit chose him.
