Hito Hito no Mi, Model: Bōsatsu

The Hito Hito no Mi, Model: Bodhisattva is a Mythical Zoan that transforms its users into a  — an enlightened being who becomes a  to save all beings, manifesting as either a hybrid or full being at will, and affording them a slew of various powers focusing on the theme of "enlightenment".

It's current user is Mahesvara — noted to be the most serene and religious of the Marines, despite his infamy for conflict, part of which stems from the fruit's side-effects. Through the fruit's mastery, he's aptly known as "Enlightened Deva" (先覚天存, Senkaku Tenzon).

Appearance
When Mahesvara obtained the Devil Fruit, it was in the garden of the Kano Province where he lived; according to him, it looked like a very large bright-yellow onion crop that was uniquely shaped like a lotus flower, had various greenish spots near its peak, green stems jutting from the top, and had swirls over its surface. His boyish curiosity got the best of him, and wanting to know what else was different about the strange "fruit", he cleansed it before consuming it whole. Unlike onions, which are noted to have a powerful flavor, this one was rather tasteless, aptly related to "wanting nothing" — a key trait of a Bodhisattva, as Mahesvara compared it to eating a cloud — the fruit instantly dissolving in his mouth. From that moment, he instantly felt calmer and his thinking was much clearer — as he's reached enlightenment.

Trivia
