One Piece: I Use the Gomu Gomu Fruit to Devour Everything

He accidentally transmigrates to Drum Island and, from the start, gains a soul-mutated body that can seize Devil Fruit powers, along with the power of the Mushroom-Mushroom Fruit he has taken. But this isn't the ability Gust wants. What he longs for most is Wapol's Munch-Munch Fruit.

A few years later, he kills Wapol and takes his power. With his goal achieved, he devours ice, snow, frost, rain, soil, wood, sand, stone, and everything else under the heavens, turning them into his own strength.

Devour ice and snow to become an ice-and-snow man. Devour magma to become a molten monster. Devour wind and sand to become a desert reaper.

When the Flame-Flame Fruit combines with magma, it creates a one-of-a-kind hellfire of molten rock. He challenges Akainu to see who truly rules the flames.

When fire and lightning combine, he blazes along with sparks and thunder. Enel, you're a fake God of Thunder.

When ice and snow fuse with ice that has endured for ten thousand years, Aokiji, your freezing powers don't seem like much after all.

By the time Gust has gathered the powers of a hundred Devil Fruits within himself, he has become the strongest monster in the world, utterly unique.
