Rokushou is a mysterious Medarot, an older Kuwagata-type model (KWG-11237) bearing a stag beetle medal. Cloaked in a worn, tattered garment, he appears to wander without a master, emerging sporadically throughout the series. He first appears in episode 10, rescuing a small puppy from a river during a rainstorm.

When asked his name, Rokushou responds that it is of no importance—later explaining that it is the only thing he still truly owns. Much of his journey is driven by the search for his lost Medafighter. Though he occasionally offers guidance and support to Ikki and Metabee during Robattles, he holds little regard for battling as mere entertainment.

Instead, Rokushou is guided by a deeper purpose: protecting rare medals, including his own, and safeguarding all forms of life.
