Hiyoshi made an octopus robot named Takko (Octo-1 in English version). At first the team thought the robot was useless but then it saved Voltes when they were trapped in a forest infested with grabbing ivy plants and later when Hiyoshi has no choice but to disassemble Takko and use its parts to fix the damaged Volt Lander. Thus the sixth member of the Voltes Team was welcomed.
