These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Badass Decay: The opening of the show makes the band look pretty badass. Then they open their mouths, and it becomes really hard to take them seriously as the minutes pass.
They set the record from the beginning of the very metal opening, to the start of the pilot episode where they show how incompetent they are.
Also Toki's underwater Beatles tribute in the second episode. Or for that matter, any time Toki breaks out into a non-metal song. The aforementioned "No More Hamburger Time" falls under this category, except that the other band members join in.
Broken Base: Dethalbum II: Are the vocal legitimate death metal or screamo crap?
Also over how the writing after Tommy Blacha left compares to before. It's plenty high-quality, but has lost some of its original quirkiness and charm while becoming more plot-oriented.
Crowning Moment Of Awesome: Dethklok brings peace to the Middle East. Made even better by the fact that it's done using giant space holograms made explicitly so that the band can perform for all of Syria AND Israel simultaneously. When a soldier almost shoots an innocent girl across the border and the music begins, they look up, and we see that both are wearing Dethklok shirts. Awesome.
Telling his new assistant about his job: "You'll ask yourself 'why am I doing this'? It's because it's the most rewarding thing you'll ever do. It's something worth dying for."
Telling the band he's sorry for being too busy to spend time with them/snapping at them earlier: "You are very important. To me." He follows this up by giving a personal reassurance to Toki, who's been chronically hitting people through the whole episode, and receives a hug from the rhythm guitarist in return. The scene continues and fades out with Toki still clinging to him. Awwwww.
When a soldier almost shoots an innocent girl across the border and the music begins, they look up, and we see that both are wearing Dethklok shirts. Music connecting people and all that.
Crowning Music of Awesome: The songs in all three season finales ("Go Into the Water" for Season 1, "Black Fire Upon Us" for Season 2, and "The Beginning" for Season 3).
"Crush the Industry", the premiere song for Season 3, made better when Ofdensen rescues the concert.
RehabKlok, aka Rehab the Rock Opera.
"I Ejaculate Fire", the first track released from "Dethalbum III", hell, just the title alone is awesome.
Pretty much all of The Doomstar Requiem
Darkness-Induced Audience Apathy: Wow!Just...WOW! This may have started to become more prominent as the show draws to its close. As of season 4 onward, the story with the introduction of the Church of the Black Klok is treating the band as the good guys. While Dethklok's enemies are nasty people, it doesn't change the fact that death and destruction follow the band where ever they go. In the early seasons the show didn't seem like it had a true good guy, the main difference is that the antagonists are actively plotting, whereas most of the havoc Dethklok is responsible for happens by accident and the band's own negligence.
Ensemble Darkhorse: It's hilarious when in a show about the five members of a band, the manager manages to be the popular one. Explains why Ofdensen became an Ascended Extra, as well.
"I'M DOCTOR ROCKZO, THE HIGHLY POPULAR ROCK N ROLL CLOWN! I DO COCAINE!"
Freud Was Right: Deconstructed with Murderface, who doesn't eat food like hot dogs, bananas, etc. When a bandmate asked him if he would eat a cut-up sausage, he said no, and explained that it would look like a cut-up dick. Later in that same episode, he was seen suggestively licking a sausage link.
Harsher in Hindsight: Dethdad. Nathan says "Danbury Connecticut is more brutal than Norway." This was before Anders Breivik and Sandy Hook Elementary (~10 miles outside Danbury).
In-universe, Toki's birthday "kidnapping" in Fertilityklok could be also seen as this since he got kidnapped by Magnus Hammersmith in Church of the Black Klok.
Ho Yay: Apart from random homoerotic naivete and spending time naked in a hot tub together, whenever the band members are seen dating women, at least one of them will look suspiciously like another member of the band. Four of Nathan's dates in "Klokblocked" look like female versions of the other four bandmates, and one of Toki's dates was nicknamed "Skwisgirl" because of her resemblance to Skwisgaar.
Pickles wearing a locket with Charles' picture in it.
Ofdensen is quite a bit more defensive of Nathan than he is the other guys. In Fertilityklok, Charles is seen with the rest of Dethklok during the roast. He tolerates, and even cracks a smile at the jabs at the other band members. But when the comic jumps on Nathan by calling him "Tonto", which is not a nickname Nathan is fond of, Charles whispers something to a nearby Klokateer. Within seconds, the comic is dead from a poison dart.
Murderface has a very noticeable knee-jerk reaction to anything that could potentially make him look gay. Such as his refusal to eat phallic-shaped food.
He is later seen licking a hot dog suggestively, and acts like it's no big deal when he notices the others staring at him.
Not to mention in "Dethhealth" when he ejaculates on his doctor's face and starts hallucinating muscular, near-naked men, while thinking "I'm gay! I'm gay!" afterwards in his paranoia. It is eventually revealed that the doctor, not Murderface, was gay, and jacked him off on purpose.
In Fatherklok, he gives Skwisgaar a bath while trying to act like a father figure for him.
Then there's the whole "body heat" scene in Doublebookedklok. Doesn't help that A) he suggests it after Pickles complains that huddling together for warmth is gay, and B) He still has his arm around Pickles' chest after Ofdensen comes to rescue them.
Toki and Skwisgaar hold hands during their therapy session in Performanceklok.
Iron Woobie: Ofdensen. He is band's manager (though he's more like a single parent having to deal with five very rambunctious and Too Dumb to Live boys]]), and has to put up with their idiotic and destructive antics on a daily basis, a task that would've driven any lesser man to either become suicidal or go insane. And on top of that the band members frequently don't even appreciate what he does for them, at least until later seasons when they begin to realize how important he is to them. And yet he stays composed, calculating and Badass through it all.
I Knew It: It was a common fan guess for a while that Nathan had Native American ancestry. "Dethcarraldo" ended up confirming this, naturally in the most brutal manner possible: his real grandfather was an Amazonian cannibal chief.
Jerkass Woobie: Even the creators of the show agree, Murderface is a tortured soul who desperately needs acceptance and a cure for his extreme loneliness and sensitivity... but he is also a complete and total asshole who is repugnant in every way.
Les Yay: Let's just say that when Dethklok's moms have a little booze in them...they get a little frisky. Also, No Yay.
Moral Event Horizon: Dr. Rockzo, the Rock 'n' Roll Clown (he does cocaine) after he steals Toki's Christmas presents for the band, pawns them to buy cocaine, and then receives a handjob from Skwisgar's mother on live TV while bragging that he does cocaine.
Aww, is somebody havin' a baaaaaaad Christmas?
Myth Arc Stall: Each successive season reveals less and less about the overarching plot. Granted, the show is primarily about a band of super destructive idiots, but it would be nice to learn a few more details about what's going on. The Season Four finale, "Church of the Black Klok", reveals a lot of information about the Myth Arc. Here goes:
After Salacia's brainwashing in the Season Two finale, General Crozier worked to get a top secret military project called "Falconback", which involves building a large scale military force that includes missiles and gigantic armies placed around the world, sneaked past Congress through a military spending bill. The plan hinged on the release of the new Dethklok album; since that album would boost the economy to obscene levels, nobody would think twice about passing the military spending bill Falconback would end up attached to. Once Dethklok's new album ended up destroyed and lost at sea, the Falconback plan returned to the backburner.
While the failure to launch Falconback did not bother Salacia, the band's potential breakup did threaten his plans, so Salacia revealed himself — and his supernatural powers — to Dethklok for unknown reasons (he could have meant to kill them or brainwash them into staying together), then killed Roy Cornickelson, the owner of Dethklok's record label. Salacia's actions prompted Offdensen to reveal the existence of the Church of the Black Klok to Dethklok and reveal what had happened to him after the Revengencer's attack on Mordhaus.
When Salacia brainwashed Crozier, Offdensen accidentally looked into Salacia's eyes and saw his true form — "the Half-Man" — but Salacia's gaze poisoned Offdensen with psychic toxins. The Church of the Black Klok, a secret society that believes in prophecies foretelling Dethklok as the group destined to save mankind with its music, tend to Offdensen; the Black Klok uses special poisons to kill Offdensen, then revive him and let his body heal from Salacia's poisoning. Offdensen becomes "the Dead Man" of the Church's prophecies; now literally invisible to Salacia, Offdensen stalks Crozier around the world to figure out Salacia's plans. When Offdensen finds a heavily-encoded blueprint pertaining to Falconback, he recruits Edgar Jomfru to help him decipher the blueprint — but before he can learn the truth, Offdensen has to "come back to life" to save Dethklok from signing a new record deal (seen in the Season Three premiere).
After Offdensen's Info Dump, the leader of the Church of the Black Klok tells Dethklok that he knows why Nathan destroyed the master recording of the group's now-lost album: it didn't have the right message, at the right time, and Nathan realized that he couldn't release that message to the world. The band learns that the last song of their replacement album — yet to be written and recorded — could become the key to saving mankind, stopping Salacia's plans, and averting the Metalocalypse for good. After the Season Four finale, however, the band must find Toki and album producer Abigail — kidnapped and injured by the Revengencers — before it can make this last song...
Narm Charm: Played deliberately in most of the more upbeat numbers in Doomstar Requiem, particularly the Klokateers dancing in "Tracking", Nathan's Elvis impersonation in "How Can I Be a Hero", and the "Thriller" parody in "Givin' Back to You".
Nausea Fuel: Dear God, the episode where they drink bleach because they think it'll help make them healthier. Some viewers dry-heaved.
Season four's funeral fight, especially the way the Revengencers make their entrance to kill everyone. Rising out of the ground like zombies.
Paranoia Fuel combined with Digital Piracy Is Evil: If someone pirates Dethklok's songs, the group have UN-sanctioned authority to legally kidnap, imprison, and torture the pirate; their importance to the world economy depends on having the ability to stop piracy.
Periphery Demographic: The show is obviously aimed at the 18-34 male demographic, but has attracted quite a lot of female fans.
How Murderface gets injuried in 'Religionklok". He lands face first on pavement while flying, resulting half of his face being completely ripped off. And then add to the fact his legs get run over.
Tear Jerker: Toki and Pickles talking about how much they miss Charles in the season 3 premiere. Kind of ruined when Pickles - while staring at a locket in which he keeps a picture of Charles - says that admitting sadness makes you gay.
"What if I'm not around in the future?"
"Do It All For My Brother" from Doomstar Requiem, where Edgar mourns his brother.
Took a Level in Badass: Listen to The Dethalbum, then The Dethalbum II. Notice the increase in musical awesomeness from one album to the next?
And now do the same, but with Dethalbum II to Dethalbum III, beginning with "I Ejaculate Fire", yeah...
Ugly Cute: Recent episodes pretty much establish the band as overgrown 12-year-olds with daddy issues (except for Nathan, who gets along great with his father), which has given them a sort of bulldog-esque "D'awwwww" factor, believe it or not. Murderface is both the ugliest and the most childish.
The Woobie: Everyone in the band, and Ofdensen in well, have seriously screwed up back stories.
