One Piece: The One-Punch Giant

Reborn as a giant berserker, he eats a Mythical Zoan Devil Fruit and crushes every enemy!

In this world, four 'Kings' possess the power to destroy the world:

the Sea King, the Sky King, the Underworld King, and the King of the Earth, Eren D. Gaia!

He may not be utterly wicked, nor particularly righteous, but anyone who stands against him will die!

That... is the motto of Eren, the King of the Earth.

PS: Mainly action and passion, with a harem on the side.

PS2: The story won't move too quickly, and the plot will be reasonably paced. This isn't just a pure power fantasy.

PS3: Besides characters from the original One Piece, female leads from other anime will appear, reimagined in the One Piece setting. This makes it easier to find pictures, and everyone will recognize them.

This novel and its characters are entirely fictional. Any resemblance is purely coincidental. Do not imitate.
