Terrax

Tyros was once the dictator of the city Lanlak on the planet Birj, where his superhuman ability to command rocks and earth enabled him to overcome all resistance. His rule of Lanlak came to an end when he was sought by the world-devouring Galactus to serve as his newest Herald. Galactus sent his sometimes-adversaries of the Fantastic Four to apprehend Tyros and bring him to receive the Power Cosmic. Tyros resisted them, but to no avail. Galactus made Tyros his new Herald Terrax, and the power cosmic magnified his abilities, making him far more powerful than he had been before.
