غورو غورو نو مي

Debuting in the thirteenth theatrical film, this fruit falls outside the canon and belongs to the Paramecia group, granting sweeping command over gold. Gild Tesoro is its sole wielder. The fruit had once gone up for auction under the Donquixote Pirates, who never meant to sell it, before Tesoro seized it through a scheme that left many dead.

Its idea echoes the legendary golden touch of King Midas, turning whatever the holder handles into precious metal.

Every scrap of gold the wielder has touched obeys them, sliding between solid, molten, and fine powder so it can take almost any form. People can be sealed inside gold like statues, and the user may wrap themselves in golden plating or balloon into a giant golem. Soft though gold usually is, active control hardens it enough to shrug off Luffy's Gear 4 and Zoro's blade techniques, and the amount on hand can be multiplied enormously.

Awakening the power widens its reach, threading the user's senses through all the gold they have handled into an elaborate detection web that registers any disturbance. The core limit is that the fruit conjures no gold of its own, so its strength depends entirely on how much metal surrounds the wielder, and only gold already touched will answer. The standard Devil Fruit weaknesses round out the drawbacks, and immersion in water nullifies the power just as it did in the Midas legend.

Tesoro raises great fountains of liquid gold, ensnares enemies, and works dust into people's bodies to slowly petrify them or to steer everyone aboard his ship. Having awakened the ability, he treats Gran Tesoro's gold as a sensory net that flags break-ins and attacks, and his larger constructs can loose explosive beams strong enough to sink a Marine warship.

Among his named moves are Gold Splash for spectacle, Gon Bomba, an exploding gauntlet punch, and his final trump Golden Tesoro, a giant golem piloted from within that fires the eye-beam Gon Fuoco di Dio and delivers the crushing Gon Inferno.
