Gravis is the ruthless first among the Tractators, a species that assimilates organic minds to animate their excavation technology. His voice carries calm authority, masking a fundamental ruthlessness beneath measured detachment. He approaches conquest with alien logic, framing planetary domination as cooperation and replacement of 'useful parts' as necessary maintenance. Though physically bound to Frontios, his obsession with mobility drives every interaction with the Doctor and Tegan, revealing an underlying desperation beneath his cold confidence.
