Transmigrating from birth into the world of One Piece, he became the World Government’s strongest talent in 800 years: the CP9 killing machine, Rob Lucci.

By all rights, this should have been the ultimate overpowered transmigration. But thinking of his future self—first sent to work as a shipwright in the trenches, failing the mission, then treated like a roadside nobody, and finally returning as a king yet still mocked as “the Ultimate Brother” by the world—Lucci felt his prospects were completely doomed.

He faced Red-Haired Shanks head-on with fierce dominance.

Duels with Mihawk in swordsmanship.

Brawled with Garp in hand-to-hand combat.

Travel through the world of pirates, carrying a treasure appraisal system with you. An apple was identified as a Devil Fruit. A gold coin was identified as a Destiny Coin, which can withstand three fatal attacks. Ace's necklace was identified as the Entei Necklace, doubling the wearer's fire power. The beads can be manipulated to transform into giant fireballs that chase enemies, and any enemy hit with the beads restores health. The Alabasta Golden Scepter was identified as the Horus Scepter, allowing two or more Devil Fruit-bearing objects to exchange their Devil Fruit abilities. This can only be used once! Smoker's cigar, Nami's weather stick, and Usopp's slingshot all underwent dramatic transformations after being identified. So much so that Im exclaimed, "A fruit even more powerful than the Sun God Nika has appeared!"...
