Mohji, first mate of the Buggy Pirates and member of the Buggy and Alvida Alliance—later the Cross Guild—earns renown as “Mohji the Beast Tamer” for his inseparable bond with his loyal lion companion, Richie. His evolving appearance reflects shifting arcs: a teddy bear-shaped hairstyle in Orange Town, a pink bunny-eared helmet in Loguetown, a lion’s mane in Jaya, and a ram-like style in Impel Down. Post-timeskip, he adopts a panda-inspired hairstyle and a dark blue fur suit, his physique notably heavier.
Introduced in the Orange Town Arc, Mohji obeys Buggy’s order to capture Zoro, confronting Luffy instead. When Richie’s attack falters against Luffy’s rubber powers, Mohji flees, warning Buggy and sparking the crew’s clash with the Straw Hats. After Buggy’s defeat, Mohji and Cabaji vie for leadership until Richie inadvertently knocks both rivals unconscious. In Loguetown, his attempt to burn the Straw Hats’ ship fails due to rain; Usopp discovers him mid-slip, leaving him unconscious before he rejoins his crew.
During the Summit War Saga, Mohji implores Alvida to rescue Buggy from Impel Down but begrudgingly accepts Buggy’s presumed demise. Upon Buggy’s return post-Marineford, he tearfully celebrates his captain’s survival, later introducing himself to Impel Down escapees. After Buggy becomes a Warlord, Mohji benefits from the crew’s pardons. Post-timeskip, he operates on Karai Bari Island under Buggy’s Delivery, eventually aligning with Cross Guild following Crocodile’s takeover.
In non-canon *One Piece: Stampede*, Mohji attends the Pirates Festival as part of Buggy’s crew, aiding security and pursuing Trafalgar Law before the Straw Hats disrupt their efforts. His personality blends theatrical bravado with comedic ineptitude, exemplified by his rivalry with Cabaji and fierce devotion to Richie. He fiercely protects the lion, reacting with outrage to any harm against him. Though boasting taming prowess, his combat relies solely on Richie and a whip. Unwaveringly loyal to Buggy despite repeated failures, he adapts pragmatically to Cross Guild’s rise, maintaining his role as a secondary yet enduring figure within the crew’s chaotic exploits.
