General Rildo

Rildo is Dr. Myuu's general and the commander of Planet M-2. He ordered Giru to lead Goku, Trunks, and Pan to Planet M-2, so his Sigma Force robots could capture them. He fights against Goku, transforming twice in the process. Soon Goku learns that Rildo's mind is programmed into the metal covering Planet M-2; meaning that Rildo can control all metal and that even if Goku destroys his body, a new one will form from the metal. Goku is defeated by Rildo and sent to Dr. Myuu's laboratory
