One Piece Wiki

Mad Treasure is the main antagonist of the Heart of Gold special.[1] He is the captain of the Treasure Pirates and a notorious treasure hunter hired by Gild Tesoro to find the extraordinary treasure Pure Gold.[2]


Mad Treasure without his glasses.

Treasure is a dark-skinned (pale in character designs by Oda and in Movie 13) muscular man with very wild and spiky purple hair. He wears dark gray pants pulled up to the knee, a red belt, and gray boots with red lining. He has two tattoos of gears with spirals inside them; one is on his left shoulder, and the other is on his right hip. He wears a pair of sunglasses and his body is decorated with chains that he can create with his Devil Fruit ability. Under his glasses, he has pink eyes.[1]


Mad Treasure is greedy, thrill-seeking, and psychotically driven by his unrelenting dream of hunting for all the treasure in the world; whether through discovery or piracy. Unlike his crew, Treasure has little to no interest in money nor the loot he already acquires. His single-minded drive for the excitement of finding a treasure is the only thing that he values in life, and will more excited the more challenging obstacles become in his quest to obtain it. He also has a selfish desire to steal the Pure Gold for himself as an exception to become immortal and live forever hunting his namesake; even going far as to walk in Bonbori's stomach acid to savor the moment of acquiring it.[3]

Treasure's desire for hunting his namesake makes him view friends and people alike as mere tools whose only purpose is to assist him in his quest when needed. Treasure will enslave anyone he finds useful enough to his hunt, and puts them in servitude with his Devil Fruit ability with no care for their well-being. He even goes far as to believe having both dreams and friends is too "greedy" to go together; prioritizing his treasure-hunting dream over his crew at any cost.[3]

Like many other people, he has a unique laugh: "Jararara".[3]

Abilities and Powers

Mad Treasure is well reputed in the New World and beyond as an infamous treasure hunter that even Tesoro would acknowledge his merits and employ him as his sponsor. As the captain of the Treasure Pirates, Mad Treasure has full authority over his crew in addition to being its strongest member.[3]

Physical Abilities

In battle, Mad Treasure is a formidable fighter with tremendous strength combined with his Devil Fruit abilities; being able to fight an agent of CP0 and come out the victor. He was also able to fight toe-to-toe with Monkey D. Luffy, a pirate from the Worst Generation, and hold his own before defeat. His body also has considerable endurance in hazardous environments, as he was able to survive submersion in Bonbori's stomach acids while not expressing any feelings of pain.[3]

Devil Fruit

Further information: Jara Jara no Mi

Mad Treasure ate the Jara Jara no Mi, a Paramecia-type Devil Fruit which allows him to create and control different types of chains from his body. He uses chains primarily for combat, which he effectively wields them as powerful blunt weapons offensively and defensively in a variety of different uses. Treasure also uses his chains for capturing and binding people into submission, and they cannot be broken without sufficient force.[3]



Treasure catches Nami and Carina.

Treasure caught Nami and Carina while they were trying to steal his treasure. Carina managed to use Nami as a decoy to escape while Nami was nearly killed by Treasure.[3] However, as Nami was about to be executed, Carina returned and lured Treasure away, allowing Nami to escape.[4]

Heart of Gold

Treasure fights a CP0 agent to get Myskina Olga.

Treasure was hired by Gild Tesoro to find the valuable treasure known as Pure Gold, and he tracked down Myskina Olga, the only person with knowledge of its whereabouts. Treasure and his crew attacked the Marine convoy carrying Olga by surprise, dispatching all the Marines that got in their way. Treasure went belowdeck to confront the CP0 agent and Marines who were guarding Olga. Treasure clashed with the CP0 agent, and eventually managed to overpower him as he returned above deck and captured Olga. However, Olga managed to escape on her steed Elizabeth, and Treasure decided to continue the pursuit.[3]

Treasure later confronted the Straw Hat Pirates, who were harboring Olga on the Thousand Sunny. While his men unsuccessfully attacked, Treasure pulled Olga back to his ship, but was unsuccessful as Roronoa Zoro freed Olga and caused her ring to slip off her finger. A giant fish named Bonbori then arrived to eat the ring, and Treasure decided to sail into its mouth along with the Straw Hats. Treasure rammed the Shark Emeralda into the Thousand Sunny, which led to Monkey D. Luffy becoming separated from his crew. The Shark Emeralda and Thousand Sunny then fell into Bonbori's throat, which excited Treasure. The fall rendered Straw Hats Nami, Nico Robin, Tony Tony Chopper, Brook, and Usopp helpless, and Treasure captured them.[3]

Treasure captures some of the Straw Hats and regains Olga.

Treasure later confronted Luffy and Olga inside Bonbori's first stomach, and after a brief clash he showed Luffy his captured crewmates. This allowed Treasure to bind Luffy and recapture Olga, and he left Luffy to be dissolved by the tide of stomach acid as he, his crew, and his prisoners departed. As the Shark Emeralda was sailing for Alchemi, Treasure came to the bottom deck and forced the Straw Hats to work, and he recognized Nami.[3]

Treasure's group later arrived at Alchemi, and prepared to enter a temple where the Pure Gold was located. However, the temple was full of traps, and Treasure used the Straw Hats to pass them. After the first test, Psycho P returned from his mission to report that Luffy was still alive, to Treasure's shock. Treasure stationed Psycho P and Naomi Drunk outside, and his group came to the Final Gate. Treasure laughed as the Straw Hats were unsuccessful at opening it, but the gate was suddenly destroyed by Luffy. Treasure battled Luffy, but Luffy's companion Myskina Acier suddenly intervened as he opened a trapdoor underneath the Straw Hats and Olga. Treasure confronted Acier, who activated a sequence for the temple to self-destruct in order to bring down Treasure with him.[3]

Treasure is defeated by Luffy.

However, Treasure captured Acier and leaped outside, right where the Pure Gold lay. Treasure picked up the Pure Gold and became ecstatic about finding it, but Luffy suddenly interrupted him. The two fought once more as Treasure struggled to comprehend Luffy's valuing of friends over treasure. After exchanging blows, Treasure wrapped his entire body in chains, but Luffy eventually managed to break through the chains and send Treasure flying into the wall of Bonbori's stomach. This caused the Pure Gold to fall off Treasure, and he waded through Bonbori's stomach acid to look for it despite the pleas of his crew. Treasure survived the acid, but was unable to find the Pure Gold. Now left stranded in the belly of the beast, he resigned to his fate and later ate meat on the shore of Alchemi with Naomi and Psycho P.[3]
