Magma, usually called “Ambassador Magma,” is the protagonist and title character of Ambassador Magma, a science fiction shounen series which began serialization in 1965. In this series, Magma was created by the same spirit which created the Earth itself, to protect the Earth from an evil spaceman named Goa. He is one of three such creatures; the others look and act as his wife and son. Magma forms a friendship with a newspaper reporter named Murakami Atsushi, whose family are the only humans to whom Goa’s plans to take over the earth have been revealed. It is to this man that Magma gives a special whistle which can summon him and his “rocket-man” family. (Source: Tezukainenglish)
