Based on confirmed materials for "Uchuu Enban Dai-Senso" (including its manga, film, and later Grendizer adaptations), no character named "Danbei Makino" appears. The film features documented characters like Duke Freed/Daisuke Umon, Telonna, Blaki, and Genzo Umon. References to "Makino" occur solely in unrelated franchises such as "One Piece," while "Danbei Makiba" is a distinct character from the subsequent "UFO Robo Grendizer" series.
