Byakko stands as one of the four main antagonists for the Kitoralsus organization in the story's initial arcs, first confronting the Shinkansen Ultra Evolution Institute and its pilots in Episode 02. His most prominent involvement unfolds in Episode 40, "Go Underground!! Shinkalion vs. Byakko," where he battles the Shinkalion E5 Hayabusa, piloted by Hayato Hayasugi, and the Shinkalion Doctor Yellow, piloted by Ryūji Kiyosu, deep within the Underground World. This decisive clash showcases tactical coordination between the two Shinkalion pilots, with Ryūji acknowledging Hayato's unconventional strategy during their pursuit.

Following the first season, Byakko's role drastically diminishes. He makes no speaking appearances throughout the entire second season. His sole later appearance is a non-speaking cameo in the season 2 finale, confirming his continued existence without active participation in the conflict. No additional information exists regarding his background, motivations, character development, or appearances in other official media like films, OVAs, or spin-offs.
