Ambassador Magma - S01

The alien conqueror Goa threatens Earth with invasion, first warning the Murakami family-father Atsushi, mother Tomoko, and son Mamoru-by teleporting them to a prehistoric jungle and obliterating a giant dinosaur before their eyes. When they refuse to surrender, hope arrives in the form of Magma, a golden, armored giant with long hair and antennae, and his human-sized wife Mol. Created by the wizard Earth to defend the planet, they bond with Atsushi and Mamoru. Magma, moved by Mamoru’s presence, longs for a child of his own, so Earth crafts a duplicate of Mamoru named Gam. Earth also gives Mamoru a whistle to summon Gam, Mol, and Magma in emergencies. When Goa sends his monstrous creatures to attack, the heroic trio often rushes in to save the day.
