General Victor Crozier is a high-ranking four-star United States Army General and one of the primary antagonists, Crozier is a core member of The Tribunal, a secretive, illuminati-like group that monitors the apocalyptic threat posed by the death metal band Dethklok. Crozier attempts a direct military strike to eliminate Dethklok, but his plans are thwarted when the Tribunal's leader, Mr. Salacia, uses mysterious psychic powers to mind-wipe him. By the end of season 2, Salacia completely breaks his will, turning him into a mind-controlled thrall. Despite his ruthless tactics, Crozier is often the most grounded and realistic member of the Tribunal. He frequently questions whether the band's regular, chaotic antics are actually part of a grand prophecy or just extreme stupidity. While physically and mentally tough, he is not invincible. After being mentally broken and possessed by Mr. Salacia, his aggressive nature is twisted into blind, robotic compliance. However, his core sense of duty remains; once he breaks free from the mind control, he is instantly horrified by his actions and seeks to fix the damage he caused. Within the Tribunal, Crozier acts as the anchor to reality. While other members obsess over ancient prophecies and mysticism, Crozier focuses on concrete logistics. He frequently questions whether Dethklok's chaotic actions are truly part of a grand magical plan or just the result of the band being incredibly stupid. He is a big softie on the inside but sometimes keeps his ruthless composure.

Senator Stampingston is a prominent antagonist, he serves as a primary member and the main presenter for The Tribunal, a secretive, Illuminati-like organization that monitors and attempts to control the massively influential death metal band, Dethklok. Unlike more reactive members of the Tribunal, he maintains a calm, highly professional, and diplomatic approach to handling the "Dethklok threat," usually advocating for espionage and information gathering over direct military action. Stampingston's primary narrative function is to open episodes by presenting Dethklok’s latest economic and cultural disruptions to the rest of the council. He frequently introduces bizarre, niche specialists to analyze the band's behavior. He is a bit of a softie.
