"Managing this band is the hardest thing you'll ever do in your life. You won't be thanked for your work. No one will remember your birthday. People will take you for granted. And, like I said, your life will be in constant danger. You'll ask yourself, 'Why do I do this?' And ultimately, you'll know that it simply needs to be done. It's the most rewarding thing you'll ever do. It's something worth dying for."
— Charles Foster Offdensen
Legendary Death Metal band Dethklok encounter both intelligent and strong willed allies and cunning and deadly enemies as the world hurtles towards the metal apocalypse.
All spoilers are unmarked. You Have Been Warned!
- Charles Foster Offdensen is the manager of Dethklok and the man who singlehandedly keeps their multitrillion dollar enterprise operating and successful. Charles is a genius accountant who plans the band's ridiculously complex and expensive concert venues and the wide variety of mass market merchandising. Utterly professional, he also ensures the five manchildren that form the band are satisfied despite giving him no respect and proves a brilliant tactician and leader that commands the undyingly loyal Klokateers in protecting the band from threats like the Revengencers and the mysterious Tribunal. Beneath his calm exterior, Charles is also a ruthless businessman who has everyone from digital pirates to insulting media kidnapped and imprisoned for threatening the band's welfare. Secretly, Charles has been working with the Church of the Black Klok to ensure the culmination of the Metalocalypse Prophecy so that his cherished band can ascend to godhood and stave off the doomsday sought by the demonic Mr. Salacia.
- General Crozier is the US military's liaison to the Tribunal, and owner of the most functional moral compass of the bunch. Genuinely concerned about the bizarre disasters Dethklok's music tends to cause unlike his power-hungry colleagues, Crozier chafes under Mr. Salacia's continued insistence that the Tribunal do nothing. Acting without Salacia's sanction, he attempts repeatedly to have the band members assassinated, only to be caught and brainwashed by his sinister superior. Enslaved by Salacia to reroute military resources for his endgame, Crozier nevertheless uses his few moments of lucidity to discover how the villain's powers work and develop countermeasures to them. Freed while Salacia possesses William Murderface in the finale, Crozier makes peace with Dethklok, teaching them how to exorcise Murderface and assisting in the deployment of their worldwide stage for their final concert. When last seen, he asserts his freedom once and for all by ordering the US Army into the final battle on Dethklok's side.
- Magnus Hammersmith was once the rhythm guitarist for Dethklok until a sudden bout of violent outbursts led him to being kicked out of the band. Magnus swore vengeance for the pain of his shattered brotherhood and for being left behind as the band became world renowned. Later joining the Masked Metal Assassin and his Revengencers, Magnus met his replacement Toki Wartooth incognito at a band camp and became his closest friend after saving his life from bullies. He uses this connection to set the band up for a surprise attack at their record head's funeral and kidnaps Toki to be used as bait. Psychologically tormenting Toki, he reveals his intent to imprison the band and have them fade into obscurity like everyone else they abandoned. Seeing the Assassin's brutality ultimately causes Magnus to turn against him and finally end his own life when he sees he was the true villain.
- Ishnifus Meaddle is the High Holy Priest of the Church of the Black Klok and dedicates his life to ensuring the Metalocalypse Prophecy comes to fruition. Seeking to stave off Doomsday, Ishnifus has secretly kept Dethklok safe countless times while allowing their Curse to kill countless people during their concerts. He later resurrects Charles after his death and makes him invisible to the sight of Salacia in the process, all the while training Charles to take his place as the next High Priest. When Toki is kidnapped and Charles is unable to help, Ishnifus leads the band to the rescue and provides a distraction to allow them to escape. Staring down execution by the Masked Metal Assassin, he dies without fear knowing his life's work would soon reach its conclusion.
- "Bluesklok": Mashed Potato Johnson sold his soul to the Devil to become a world famous Blues musician and becomes the mentor to Dethklok when depression prevents them from playing. Johnson puts the band through rigorous and cruel training methods to have them master the Blues before having them sell their souls to the Devil as well. Deciding a hippie music festival desperately needed the Blues, Johnson looks on in satisfaction as the band skillfully puts their lessons to the test and destroy the festival when their music summons storms and tornadoes.
- "P.R. Pickles": Liz Bane was once an infamous cult leader that led numerous massacres yet always used her dark charisma to evade convictions. She later uses her skills to create the most successful public relations firm in history and turns Pickles into the world's most famous celebrity. She then manipulates him and the band by proxy to gather a horde of mind controlled followers, and then tries to kill them all in a concert by colliding a meteor into them. Nearly escaping with all their wealth, she only meets her end when Salacia magically forces the comet to kill her instead.
- "Dethsources": Melmord Fjordslorn is hired by Dethklok to be a perfect manager to hang out with and indulge their desires when Charles proves too stoic and distant. Melmord casually ingratiates himself with the band by taking drugs and alcohol and sleeping with groupies, all the while slowly turning them against Charles to have them sign over managerial powers to him alone. With the band in his hands, he ambushes Charles and challenges him to an extended rapier duel. Cornering his rival and on the cusp of victory, Melmord only loses and dies after a last skilled parry by Offdensen.
- "Rehabklok": X2P1158 is a drumming robot put in the band to replace Pickles after a round of heavy drinking causes disaster and he is sent to rehab. X2 predictably gains sentience and wins over the band when his masterful drumming and quick adaptation to the rocker lifestyle overshadows the now sober Pickles. Proving more popular with fans than the other band members, a jealous Dethklok fires X2 and is kidnapped by the robot in vengeance. Imprisoning Pickles to stop his interference, X2 nearly blows up the band before a drunken rampaging Pickles destroys the bot even as it tries to take Pickles with it.
