Sergeant Metallic

メタリック軍曹

Among all the challenges in Muscle Tower, Goku's second trial - getting past Sergeant Metallic (also known as Full Metal Jacket) - was undoubtedly the most difficult. Because Metallic was a robot, he was extremely tough, and truthfully, the only reason Goku won was that the major's batteries ran out of power. In the anime, Goku accidentally blows off Metallic's head with a Kamehameha, but even that does not stop Metallic from continuing his rampage. Even without a head and eventually losing both wrists, he repeatedly tried to stomp Goku flat. It was the first time in the series that someone was actually able to take a few hits from the Saiyan warrior and survive. Metallic appears for a few seconds in Dragonball GT, firing his fist and causing major damage to a building. Stylistically, he is an obvious tribute/parody of The Terminator played by Arnold Schwarzenegger.
