Magma Taishi

Goa, an alien invasion, plans to rule the Earth. He initially alerts the Murakami family—father Atsushi, mother Tomoko, and son Mamoru—about their impending invasion. He then shows off his abilities by teleporting the family to a jungle environment where they witness him slaying a giant dinosaur. However, they are unwilling to submit to Goa, which is why Magma, a golden, armored giant with long hair and antennae, represents hope. The wizard Earth sent him and his human-sized wife Mol to protect our planet from Goa. They become friends with Atsushi and Mamoru. Mamoru's desire to have a child with his wife Mol moves Magma to tears, so Earth makes a copy of Mamoru called Gam. Mamoru receives a whistle from Earth, which he can use to summon Gam Mol and Magma in an emergency. Magma, Mol, and Gam will likely fly to the rescue when Goa unleashes his different daikaiju.
