Description
Caterpillio Zōmyōji serves as the mechanic for Goha 6th Elementary's Heavy Cavalry Duel Club, maintaining and supporting the club's equipment and dueling assets. He sports light grayish orange overalls with grayish red visible on the rolled sleeves, brown boots, spiky brown hair, and blue eyes. His accessories include ash-white gloves, a cap, and a screwdriver strapped to his back; he initially concealed his identity behind a silver mask.

In duels, Zōmyōji utilizes an EARTH Beast Deck focused on defense. His strategy involves placing monsters like Barrier Armadillo (three copies), Covered Hippo (a Level 6 Normal Monster with 200 ATK and 2100 DEF), and Mega Elephant the Mobile Beast Cavalry (a Level 8 Effect Monster with 1700 ATK and 2500 DEF that revives a Level 6 or lower Beast-Type Normal Monster from the Graveyard) in Defense Position. He combines these with Trap Cards to pressure opponents into self-inflicted damage. His support includes the Field Spell Beast Battlefield Barrier (reducing all monsters' ATK by 200 while boosting Normal Beast-Type DEF by 400), Shield & Sword for offensive plays using high DEF, and two copies of Rut Trap.

His documented duels include a loss to Tiadosia Kallister in Episode 35 and an off-screen group victory alongside Asana Mutsuba, Galian Townsend, Schubel Quill, and Tiadosia Kallister against Goha 66 members in Episodes 46–47. As a secondary member of the Heavy Cavalry Duel Club, he operates under Asana Mutsuba's leadership, fulfilling his consistent role as the club's mechanic and a participant in collaborative duels within their military-inspired structure.
