Magma Taishi

An evil dinosaur-wizard-alien named Goa plans to take over earth and get rid of all the humans living on it. Earth, the creator of earth, makes three “Rocketonians” to stop him: the golden giant Magma, his mostly absent throughout the whole series wife Mol, and their son Gamu, who is made in the image of the main character, Mamoru (a human boy).
