Hailing from the Bow Wow Wow Cluster, Bochi shifts between two forms: an unassuming dog and a powerful, bipedal warrior. Sustaining his muscular warrior state consumes immense energy, causing reversion to canine form upon depletion. Historically, this ability enabled the assassination method called the Wicked Fist of the Beloved Dog, infiltrating territories as a dog before executing surprise attacks. Bochi now rejects this technique, considering its stealth approach cowardly.

He serves as the pet dog to Manya Atachi. Bochi's warrior transformation occurred publicly during one of Manya's Rush Duel training sessions. To downplay the incident for observers, Manya attributed this sudden change to the "power of TV."
