Bana Bana no Mi

Introduced in a One Piece live stage production, this power sits outside the main story and was consumed by the pirate Bounty. Rather than drawing on an outside element, the fruit feeds on an emotion, taking the wielder's jealousy and turning it into thermal energy and fire.

The naming plays on bānā, how the English term burner is spoken in Japanese, which fits a power built entirely around scorching heat.

Output scales with feeling: the greater the eater's envy in the moment, the more intense the heat they generate. The user can wreath their own body in flame, and they can also channel that warmth into anything they hold or anyone they lay hands on.

Beyond the ordinary drawbacks that affect every Devil Fruit eater, no additional limits have been documented for this ability.

Bounty is the only wielder. He fights by battering foes with heated blows and by seizing hold of them to cook them from the outside in. His named techniques run through a series of burner-themed strikes, among them Burner Knife, Burner Gun, Burner Knuckle, Burner Chop, and the finishing Burner Explosion.

Heat generation is not unique to this fruit within the franchise; four other powers, the Kachi Kachi, Atsu Atsu, Gutsu Gutsu, and Netsu Netsu fruits, also produce warmth by various means.
