Dethklok is a fictional melodic death metal band featured in the Adult Swim animated television series Metalocalypse, known for its satirical or parodic lyrical themes.

The band embarked on a USA tour from August to October 2023, with co-headliners Babymetal and supported by Jason Richardson.

The band's fan base includes billions of metal fanatics, who frequently endanger themselves watching the band perform live, as their costly shows are commonly held in dangerous locations and include numerous hazards such as excessive pyrotechnics, aircraft, lasers, and giant bladed pendulums, with many shows concluding in multiple attendee deaths.

[12][13] With their widespread commercial success and lucrative sponsorship contracts, Dethklok is ranked as the world's seventh largest economy by the end of the second season.

The band struggles to perform everyday tasks, including grocery shopping, preparing food, and maintaining proper social relationships.

Throughout the series, they are often assisted by their manager and lawyer, Charles Foster Offdensen, who frequently attempts to prevent the band from making poor decisions.

He is the lead songwriting force in Dethklok, and uses violent imagery or plot elements when writing and composing song material.

Nathan is slightly more sensible than the rest of the band, and a great deal more emotionally stable, though he is still incompetent at most things in life such as the use of a grocery store or reading a cooking recipe.

He attempts to get his GED in "Go Forth And Die", and only fails in part due to the band's influence, and in "Fatherklok" tells Murderface not to interfere with Skwisgaar's father issues.

Small described Nathan as a "quarterback", in part to his contribution to his high school football team, and based his character's appearance and performance style on current Cannibal Corpse vocalist George "Corpsegrinder" Fisher.

Show creator Brendon Small compares Skwisgaar's attitude and technical playing style to Yngwie Malmsteen.

A native of "an abandoned town near Lillehammer", Norway, he was forced to constantly perform manual labor by his abusive cultist parents.

[15] In contrast to the deep cynicism, grim outlook, promiscuity, and alcohol abuse of the other band members, Toki's character is generally childlike, innocent, and good-natured, yet traumatized and can be quite violent when pushed too far.

He has a boyish bedroom complete with action figures, stuffed animals, and wall posters, and a prominent hobby of his is building model planes.

He refers to himself as "very Irish American" and has long red hair, styled into dreadlocks and a comb-over skullet, and green eyes.

He is depicted as having an average build with a strong propensity for drugs and alcohol abuse stemming from feelings of resentment towards his family.

[16] Pickles is the former front-man of a group called Snakes 'n' Barrels, providing the vocals and performing as the lead guitarist.

Brendon Small describes Murderface as "thin-skinned and incredibly sensitive and just wants to be accepted constantly but can't get that because he's such a dick and pushes people away".

Additionally, he is generally disliked by the opposite sex to the point that even female Klokateers, who are absolutely devoted to Dethklok, reject his advances.

The band featured Brendon Small, guitarist Mike Keneally, bassist Bryan Beller and drummer Gene Hoglan.

[24] In a February 2008 interview on California radio station Indie 103.1 with Full Metal Jackie, plans for a summer 2008 tour were announced.

During the June 5, 2008, show at The Fillmore in San Francisco, an electrical fire broke out during Soilent Green's set.

Attendees were hesitant to leave the building thinking that it was part of the show (in their fictional universe, Dethklok is infamous for causing disasters that result in deaths), which created a dangerous situation, but they soon realized that the fire was real and evacuated and the concert was rescheduled.

[33] Dethklok toured North America, in support of Dethalbum III, with Machine Head, All That Remains and the Black Dahlia Murder during November and December 2012.

[36] The band then went on to tour in North America, in support of Dethalbum IV, with Babymetal and Jason Richardson from August to October 2023.
