Description
Kenzo Hyodo debuted as a 9-year-old Earth-born card battler in *Battle Spirits Shounen Gekiha Dan*, boasting tournament victories. His appearance features blue-green hair, matching eyes, a yellow ladybug headband, a green-and-white shirt, plaid shorts, and long yellow socks. His battle form manifests a yellow horned skull. Kenzo wields a green deck anchored by his X-rare spirit, *The BladeKingBeast Byak-Garo*. Though mature for his age, he reveals childish tendencies—frequent fright, impatience, and anger when provoked—alongside a noted genius intellect.

During the Grand Rolo Championship, he defeated a possessed Suzuri using *Byak-Garo* and advanced to battle Dan Bashin, declaring his wish to become invincible while revealing himself as the true green core soldier. After losing to Dan, he threw a tantrum but accepted Dan's friendship. Reluctantly joining the core soldiers' mission, he expressed concern for Kajitsu and suggested traveling to the green world to heal her. Underestimating multi-color tactics led to his defeat by Leon, who planted a tracker on his bag. Kenzo later re-challenged Leon to motivate Dan into battling; Dan intervened to share the loss. Tasked with destroying Grand Cores—a potential self-sacrifice—Kenzo hesitated but participated after the choice was emphasized. He defeated the Green Pantera robot, aided strategic efforts by implanting a virus with Mai via secret contacts, and lent *Byak-Garo* to Dan for the final fight against the Otherworld King.

In *Battle Spirits Brave*, set two years later, the 11-year-old Kenzo works as a scientist in the future alongside Stella Korabelishchikov. His updated look includes glasses, a lab coat, a bobcut hairstyle with collared shirts, and a ladybug-motif necklace. Researching Otherworld Observation Records, he uncovered the legend of the 12 Zodiac X-rares essential to prevent Earth's reset. While focused on science, he battled Plym when challenged, effortlessly defeating her with three *Byak-Garos* and sparking her infatuation. He assisted Stella in analyzing Barone's DNA—exposing mazoku-human equivalence—and located the Arctic shrine to activate the Zodiac X-rares. He witnessed Dan becoming the trigger to halt the reset. Post-mission, he returned to his time with Mai and Suzuri, prepared to "face the past again".

The *Gekiha Dan* manga depicts Kenzo teaming with Leon in a tag duel against Mai and Kazan, ending in defeat. The *Brave* manga excludes Stella, leaving Kenzo as the sole scientist.

In *Battle Spirits: Saga Brave*, Kenzo appears alongside Mai and Suzuri in their original timeline. Sensing familiar anomalies during Cardinal Sign's resurgence with the 12 Zodiac X-Rares, a mysterious card—*The Clash King's Miracle*—materializes in his deck amid the crisis.
