The character first appears in Fantastic Four #211 (Oct. 1979) and was created by Marv Wolfman and John Byrne.
The character first appears as a Birjan named Tyros, the ruler of the city-state of Lanlak on the planetoid Birj. The cosmic entity Galactus selects Tyros as his next Herald, but first wishes for the superhero team the Fantastic Four to humble him. In return the cosmic entity agrees to travel to Earth to aid the heroes against a new threat, the villain Sphinx. Tyros is defeated, and brought before Galactus, who changes the petty tyrant into Terrax the Tamer. His minor control over stone was augmented to an incalculable degree. Now, he could affect all matter of rock and stone on nearly a planetary scale. His body was changed so that it would withstand the vacuum of space. Finally, Galactus gave Terrax a weapon called the cosmic axe capable of generating waves of cosmic force. Terrax travels with Galactus to Earth and, while his new master battles the Sphinx, attacks the Fantastic Four—still resenting the heroes for their role in his transformation. Terrax, however, is tricked and defeated by the Human Torch, and leaves with a victorious Galactus.
As Galactus's new herald, Terrax found more worlds for his master than any of the previous heralds. Terrax likened the discovery of new planets to the feeling of conquest. On several occasions, Terrax annihilated large segments of the population himself using his cosmic powers. As Galactus had hoped, Terrax's lack of morality made him a successful herald. But whereas Galactus's other heralds had a sense of loyalty to their master, Terrax had none.
