Dethklok is depicted as an extremely popular and successful death metal band, described by their adversaries, the Tribunal, as the "world's greatest cultural force."
In an early version of the Metalocalypse theme song posted on Brendon Small's personal website, the voice snippets suggest that a "death clock" would be discovered and used by the members of the band.
The group's briefings are led by Senator Stampingston, who usually has experts (who often bear ridiculously complicated names) speak based on whatever Dethklok is doing in the episode.
In season 2, Offdensen became the target of the Metal-Masked Assassin after stopping him from killing Dethklok, fighting him until the event of the Revengencers attacking Mordhaus itself during the CD release party for the band's new album.
[8] As seasons 3 and 4 progress, understanding that Dethklok's music can enable people to survive the end of the world, Offdensen returns to his job and tasks of seeing over the band as if nothing had happened, save for being slightly more vigilant in his business handling.
Because his soul had been separated from his body, Offdensen is labeled as "The Dead Man" and could no longer be seen by Salacia, who sees him as a major threat with possible knowledge of his true nature.
[8] In Metalocalypse: The Doomstar Requiem, Offdensen resigns from his position as Manager and CFO of Dethklok, and becomes the new High Holy Priest of the Church of the Black Klok, after the death of Ishnifus Meaddle.
[9] Klokateers are the slavishly devoted servants of Dethklok, providing for their every need, such as maintaining the band's various properties, serving as soldiers and bodyguards, and performing as roadies for their concerts and their own personal military and police force.
He is passionately loyal to his employers, having stated he "would rather have [his] brains scooped out with a melon baller than miss the opportunity to serve the various cheese snacks to [his] beloved Dethklok", despite the job's inherent risks.
The band incompetently sewed him back together, giving Jean-Pierre a grotesque and mutilated appearance (some parts don't quite fit and/or were sewn on backward).
[12][15][16][17][18] Though his music producing later ended when Crystal Mountain Records fired him in Season 4, his replacement Abigail Remeltindrinc hires him back as the band's main engineer.
Dr. Johnathan Twinkletits (pronounced twink-LET-its, deliberately avoiding the obvious pronunciation) is an insane band therapist, and parody of performance coach Phil Towle and producer Bob Rock.
Facebones is an animated version of the Dethklok logo, with a twisted jaw and visible brain (most likely a nod to metal mascots such as Megadeth's Vic Rattlehead or Iron Maiden's Eddie the Head).
Introduced in "Murdering outside the Box", he got into a scuffle with a disguised Agent 216 (an assassin sent by General Crozier to kill Dethklok) over who had won the company's raffle draw.
The resulting fight between the two led to #216 being incapacitated; yet, #216 managed to deliver the final blow, tripping Agent 216 before he could kill the band, leading to the assassin's death via cranial impalement on Murderface's diamond-encrusted rhinoceros horn codpiece.
By the events of "The metalocalypse has begun", #216 had fully recovered from his injuries, and took part in the massive battle between General Crozier's armed forces and the Klokateer Army.
According to Brendon Small, Dr. Rockso was supposed to be an amalgam of every kind of front man from the hard-rock era, including Vince Neil, Axl Rose, and Bret Michaels.
While Pickles initially tried to earn his mother's affection by becoming the best real estate agent in the country, he eventually takes his bandmates' advice and stops caring what she thinks, coming out much better for it.
Eventually Seth was made head of Dethklok Australia, mostly out of Pickles' hatred: The previous managers had been gruesomely murdered at some point, being a highly dangerous position.
They were very harsh and even cruel to Toki during his childhood, forcing him to perform incredibly strenuous tasks for a child such as moving rocks, symmetrically stacking huge amounts of firewood and "sweepings the snow".
In "Dethdad", Toki's triumphant trek up the mountain, the rest of the band's refusal to accompany him, and the small house at the summit[32] closely resemble events in the documentary film True Norwegian Black Metal.
In the documentary, black metal vocalist Gaahl takes the American documentarians on a long walk up a snow-covered Norwegian mountain to show them a house he says was built by his grandfather.
At the beginning of Season 3, he seemed deathly ill, and his son Damien was running Crystal Mountain, using the label and Offdensen's absence to get revenge on Dethklok for humiliating him years ago.
The Metal Masked Assassin, also called "The Man With the Silver Face" by Offdensen, is the brother of Agent 216, whom Crozier had sent to kill Dethklok in "Murdering Outside The Box" only to wind up stabbed through the mouth by Murderface's diamond-encrusted codpiece.
The Metal-Masked Assassin returns as the principal villain of the 2nd Season, now wearing a metal brace on his elbow and with a consuming hatred towards Offdensen, whom he wants to suffer before killing him.
In "Bookklok", the Assassin resurfaces as the new leader of the Revengencers, attacking Dethklok at the end of the fourth season in conjunction with Magnus Hammersmith and kidnapping Toki and Abigail.
As revealed in Metalocalypse: The Doomstar Requiem, Edgar lost the use of his legs due to a car accident that occurred while he and his brother were returning from a Dethklok concert.
Eric is killed instantly, his head blown off and the remnants of his face scattered on his brother, while Edgar, remembering Offdensen's cryptic advice regarding how to cross the narrow corridor beforehand, survives, only to be promptly imprisoned inside the band's dungeon.
Though he despised Dethklok, especially their refusal to accept Toki as a brother, Edgar provided the band with gadgets to use for the rescue mission during the events of Metalocalypse: The Doomstar Requiem.
[8] In "Church of the Black Klok", Magnus reveals his true colors while stabbing Toki, but kept him alive alongside Abigail so he can exact his revenge on Dethklok during the events of Metalocalypse: The Doomstar Requiem.
