Thragg has an incredibly disciplined, ruthless, and calculating personality. He sees himself as the living embodiment of Viltrumite superiority and carries himself with absolute confidence and authority. Unlike many villains who are driven by anger or chaos, Thragg is cold, patient, and strategic. He values strength above all else and believes that the powerful have the right to rule the weak. Despite his brutality, he is not reckless; every action he takes is usually meant to further his goals or strengthen the Viltrumite Empire. Thragg is proud, uncompromising, and possesses an iron will that allows him to endure almost any hardship without breaking. He views mercy as a weakness and expects complete loyalty from those beneath him.
