Badass Decay: 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.
Nakama: They'll never ever admit it (because "it's not metal") but they care for one another and for Ofdensen, their manager. Okay, Toki may try to admit it, but they'll call him names.
Captain Ersatz: Of Swedish guitarist, Yngwie Malmsteen and Finnish singer and guitarist, Alexi Laiho.
Conversely, Guitar Hero World Tour also had a character who was a Captain Ersatz of Skwisgaar himself, complete with the exact same hair design, called Marcus Fretshredder.
Man in White: In the flashbacks, and when symbolically juxtaposed with Toki.
Money Fetish: In Renovationklok, he blows a few billion on a solid platinum practice chamber and solid ruby metronome. "It's so expensive, it makes mes horny."
Out of Focus: Of all the bandmates, he seems to get the least amount of subplots focused on him, and has the least amount of his own songs.
Really Gets Around: A running joke is that he's not very selective when it comes to groupies.
Characterization Marches On: In the pilot episode and some of season one, he is a lot more mellow and normal compared to his innocent squeeky voiced nature later on.
Catch Phrase: "Piss!" and other variants. Also "I was thinking.. not very hard, mind you".
Crouching Moron, Hidden Badass: He's mostly a moronic, mooching Ted Baxter, but the man can play bass with body parts that weren't meant to touch an instrument. He can also write music like the others, but he won't until his own money is in jeopardy.
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.
Nobody Loves the Bassist: Comes in around season two where its revealed that Nathan often time edits out his tracks on albums. The finale of season two also saw Murderface get mocked by two groupies just because he's the bassist.
Shower of Angst: After an "incident" at the doctor's office.
The Southpaw: Possibly. He signed a contract with his left hand.
Given that he plays right handed, and even refers to his right hand as his bass playing hand, its possible he's ambidextrous.
That hand was his left hand, he picks with his right.
Which is how right handed people play bass and guitar in general.
By the Power of Grayskull!: "By the power of all that is evil, I command you to awaken and MAKE ME A SANDWICH!"
Catch Phrase: "Douchebags!" or "Motherdouchebags!"
Expy: Of Devin Townsend from metal band, Strapping Young Lad (appearance), Axl Rose (being the former front man of Guns N' Roses parody band, Snakes N' Barrels) and Roger Taylor (drum playing style according to Brendon Small).
Old Shame: The former front man for hair metal band Snakes N' Barrels.
Only One Name: Unless you count his title on the band.
Self Fanservice: It seems many people who make fan art of him seem to completely ignore the fact that he is balding and has a dread-lock comb-over, giving him a flowing straight full head of hair.
Even fanworks with a less idealized art style often exaggerate the height difference between Pickles and the other band members for the purposes of humor or cuteness.
The Glasses Come Off: Subverted, the glasses usually stay on, it's the tie that comes off.
Good Scars, Evil Scars: When Ofdensen got the everloving shit beaten out of him during the season 02 finale, the Metal Masked Assassin cut his cheek quite deeply. When Ofdensen makes his triumphant return in the season 03 premiere, he has a scar from it. But after the premiere it is no longer visible, at least to the naked eye.
Disproportionate Retribution: Imprisoning him and torturing him in the bowels of Mordhaus for STEALING A FREAKING DETHKLOK SONG ONLINE.
JerkAss: When he was a carefree teen before being imprisoned.
Squick: The mask on his face Is Eric Jomfru's dead face skin given to him by Edgar Jomfru in prison.
The Voiceless: Stopped talking after he was imprisoned.
Lavona Succuboso & Succuboso Explosion
Beehive Hairdo: The red-head agent, and it's an especially weird one. (She's usually seen right behind Lavona, and is the one who tests the loin extractor in "Klokblocked").
The Voiceless: Succuboso Explosion, save Lavona. (They don't say anything besides "We are the vessels that hold the future", and always stand side to side. They're THIS close to being completely mindless).
Abusive Parents: Subverted, they are actually very good parents to Nathan overall. Still, Rose can get drunk and embarrassing, while Oscar resents Nathan for making give up his drinking to raise him.
Either this was retconned, or Oscar and Nathan patched things up. In "Fatherklok," Nathan openly states that he loves his dad and that they often hang out together.
It was hinted that Explosion Sauce patched up their relationship.
Abusive Parents: Subverted in that his grandparents who raised Murderface are jerkasses and his mom, who we know next to nothing about, doesn't fit this trope. His father who killed his wife and himself with a CHAINSAW when Murderface was an infant is a different story.
Abusive Parents: Pickles constantly has to play Well Done Son Guy to his parents, who favor Seth, Pickles' manipulative con-man of a brother. Calvert goes as far as to tell Pickles that he "...belongs in a garbage can" when he was a teen kicking him out of their home.
N.G.O. Superpower: Seth, who as the president of Dethklok's fan club in Sydney, Australia, can pull resources he needs to protect him and his family from the Revengencers, even at the risk of the safety of city.
Abusive Parents: To say she is a promiscuous slut would be an insult to promiscuous sluts everywhere. Sure her son, became a kickass guitarist because of it, but he also gained her rampant promiscuity.
The man she later married however was a pretty nice guy, too bad he married a massive slut.
Grandma, What Massive Hotness You Have: She's still sexually active at her age, and Murderface has expressed attraction towards her. She's also really a grandma to tons of illegitimate kids.
Abusive Parents: Aslaug, who is apparently a reverend, would regularly abuse and treat Toki cruelly. The level of physical and emotional abuse Toki endured form him was ridiculous, yet Toki loved his father enough to try to give him his dying wish.
It was said in "Cleanzo", that he was caucasian. His skin was much lighter, as shown in his child picture. However, his skin might have darkened from the drugs and face paint.
Catch Phrase: "I'm Dr. Rockzo and I do c-c-cocaine !"
Easily Forgiven: By Toki, over and over again. Even after supposedly having cut himself off from the clown for good.
Explained and slightly justified in Dethzazz: Toki had a doll that looked like a clown that he kept with him when he was being punished as a child, so he associates clowns with safety and happiness. Yes, even the creepy, unreliable, cocaine-addicted ones.
Zig Zagged and Played for Laughs: He does cross the line pretty often, but no matter how henious his latest deed is, he still gets redeemed somehow by the next episode... Only to cross the line even harder the next time, beginning the cycle anew.
Garfunkel: The remaining band members after Pickles left.
Hey, It's That Voice!: Each of the members of SnB is voiced by a musician: Thunderbottom by Michael Amott (Arch Enemy guitarist), Candynose by Warrel Dane (Nevermore vocalist), and Snazz by Steve Smyth (Forbidden guitarist). Ironically enough, only Snazz's instrument of choice matches his voice actor's.
