Gun-Nose's appearance is that of a rhinoceros beetle. He possesses a long "horn" on his head, hence the name, able to shoot Napalm at his foes. The leg parts have clawed toes, likely for increased grip on the ground to enhance firing stability. Both the forearms and shoulders are noticeably asymmetrical: the Right Arm has a rounded gunmetal pad and a single-barreled Rifle capable of accurate Snipe attacks while the left arm has a yellow square shoulder and multibarreled Gatling useful for more general Shooting attacks.

Gun-Nose is exclusive to the Kabuto Version of Medarot DS. He is first seen in the town's Medarot Research lab where Azuma Amakura, in disguise as a researcher, agrees to test the parts. Soon after, Azuma's own Metabee is destroyed in a confrontation with the Roborobo Gang's Sakekaasu and his leader; Sakekaasu steals the broken Medrot's body, accidentally leaving the Medal behind. Dr. Aki gives Azuma the complete set of parts for Gun-Nose and a replacement Tinpet while the Medarot decides on a new name for itself: "Gun".
