Moz, born into a warrior lineage, demonstrated extraordinary combat prowess from childhood. At seven, he nearly fatally struck his abusive father in self-defense, remaining undefeated in battle thereafter. Within the Petrification Kingdom, he and Kirisame rose as its elite fighters. Five years before the central narrative, he encountered Amaryllis and fleeing children on Treasure Island. While Kirisame petrified the group, Moz spared Amaryllis, compelled by her potential beauty and an unexplained urge to witness her adulthood.
During the Treasure Island Arc, Moz joined a harem selection, drawn to Kohaku’s strength and appearance. Unmasking her as an intruder, he dueled her fiercely. He later infiltrated the Kingdom of Science, forming a fleeting alliance to seize the petrification weapon, intending to conquer the island. Posing as an invader, he sabotaged comrades to incite turmoil. In his climactic clash with Hyoga, whose adaptive spear techniques overwhelmed him, Moz accepted defeat as a worthy end, humorously proposing a rematch if resurrected.
Following the island’s mass petrification, the Kingdom of Science recovered his statue. Revived at Hyoga’s urging, he joined the combat unit, training alongside Tsukasa, Matsukaze, and Hyoga. In New America City, he battled alligators and Stanley’s forces, integrating Hyoga’s Kan-style spear methods. His tactical pragmatism emerged when he advised adversaries to spare captives for strategic leverage.
In the South America Arc, Moz aided the mission to reclaim the petrification device. He sliced Brody’s necklace keychain, enabling Homura’s retrieval, but sustained gunshot wounds before Joel’s weapon reactivation re-petrified him. Depetrified once more, he later appeared in a tailored suit at a wedding, his striking modern look garnering attention.
Moz’s personality merges cockiness, cunning, and a thrill-seeker’s zeal. He venerates strength and beauty, openly admiring rivals like Kohaku and Hyoga. Though self-serving, his strategic intellect surfaces in deducing Kohaku’s true identity and manipulating battle dynamics. Combat mastery includes spear expertise, stealth, and raw power to overwhelm foes.
Physically, he boasts a muscular frame, brown dreadlocks in a low ponytail, and facial markings mirroring Kirisame’s. Initially armored with stone pauldrons—later replaced after destruction—he adopted contemporary attire post-revival. His capabilities peak in combat and romantic pursuits, contrasting a notably lackluster work ethic.
