In the season one finale , when Toki and Skwisgarr are about to be killed by a Psycho for Hire, Ofdensen comes by and saves them, telling the killer that "that's my bread and butter you're fucking with" and proceeds to throw his gun away, snap the guy's arm, stab him with his own knife and kick him into the sea. While in a business suit. This scene proves why he's the manager of the most brutal band to ever exist.
Also in that episode, when the US Army are closing in on the rest of Dethklok, the Klokateers come in and counter-attack. With medieval weapons vs. the army's assault rifles. While the US Army won since Crozier and Ravenwood were about to finish off Nathan, Pickles and Murderface, they did only have like five guys left. The fact the Klokateers did that much damage alone is metal.
Prior to that, taking two obsessive fans who were trying to blackmail the band and having them killed. "I suggest you serpentine." Very briefly, he grins when he gives the order to fire.
More recently, at the end of the second season episode "The Revengencers" Charles has his rematch with the assassin, who surprises him, knocks him around, and throws him out the highest story window of a hospital, only for Charles to make a perfect three-point landing on the ground below, with only a slightly bloody mouth to show for it.
Also, when the band tires to hire a new, mellower manager to take over Ofdensen's position, Ofdensen approves of Melmord's hanging around with the band— "I like it when they're happy"— but refuses to hand over his job. "I've grown quite accustomed to working with Dethklok, and, ah, you'd probably have to kill me to get them away from me." The two later fight to the death. Ofdensen wins.
Because of complications with the studio equipment, Skiwsgarr once had to record a guitar solo by more...unconventional means. In this case, by jumping out of an airplane and playing before he opened the chute.
Twice. Toki accidentally deleted the first recording, which Knubbler had forgotten to back up.
When at a concert for the revived and sobered-up Snakes-N-Barrels (Pickles' old band, now with a new front man), Toki is increasingly annoyed by a fan behind him screaming and whooping into his ear. Murderface, on the other hand, found out that Toki registered the domain name "Planet Piss" (Murderface's side project) under his own name and filled it with photoshopped pictures of Murderface in bestiality acts) just for laughs. By the time all hell breaks out at the end of the concert, Toki is in an uncontrollable rage and has beaten the fan within an inch of his life to death, while Nathan and Skwisgaar look on in utter shock. Poor Murderface picked the wrong time to confront Toki; Toki looks up from the carnage and screams at Murderface, who looks like he's about to void himself.
Toki:(While covered in blood, curb stomping a guy into the ground) WHAT THE F*guitar*S DO YOU WANTS MOTHERF*guitar*R?!
Murderface: .. What's up, bro?
Dr. Rockzo the Rock N Roll Clown. Everything he does. No, really. Especially Cocaine.
As well as his long-awaited return to the wagon. "The name's Doctor Rockzo, the rock n' roll clown. And I DO cocaine!
When Toki works overtime to try and make a reunion tour with Zazz Blammymatazz a reality, Rockzo keeps it together long enough to put on a performance that even Nathan has to admit is unbelievably kickass.
In the season 2 finale, every member of the band gets one of these.
Toki, having spent the entire episode drunk, knocks out Nathan Explosion's would-be assassin with a vodka bottle.
Murderface puts his newly found fire-marshal mojo to work, leading a woman out of the Mordhaus inferno: "Hey mama, come with me if you want to live."
Even more awesome as this may have been the same girl who ragged on bassists during "Klokbloked".
Skwisgaar kills two assailants with his guitar. He doesn't even break a string.
"And the neck's still straight!"
Pickles, staring down the barrel of a shotgun, tearfully confesses to Skwisgaar that he, of all the band members, successfully perfected the art of self-fellatio. "I can die now."
Nathan Explosion saves Ofdensen from the Masked Assassin by bashing him over the head with a burning 2x4. "That's my bread and butter you're fucking with," paralleling Ofdensen's line above. Also a Crowning Moment of Heartwarming, something you don't really expect on Metalocalypse.
Not to mention spending most of the episode carrying an incapacitated Toki out of the burning rubble while quietly lecturing him on his substance abuse problems.
Ofdensen performing a backflip from one flying bike to another while under fire after aiming his bike to take out the sonic weapon, plus any scene of him in the War Room. "Release the Deth Spiders."
Season Three starts off pretty grim for Dethklok. With Ofdensen apparently dead from the end of season two, the band is left at the mercy of a tyrannical record exec who is trying to renegotiate their contract in retribution of Nathan punching him when they first met. At one point, Nathan is about to cave in to the label's demands when suddenly a bright light shines out from behind the band. It's Ofdensen, clad in a leather jacket and sporting a badass scar. The exec moves to strike him but is stopped by Nathan's fist in his face (again!). Ofdensen turns to the band telling them to play their show while he "has a little chat" with the record head. My dorm room erupted in cheers. Just goes to show that NO ONE messes with Dethklok.
The fan response to Ofdensen's return was so strong, it was later jokingly stated to have caused a coast-to-coast earthquake in the US that morning.
Ofdensen is averaging at least one per season so far.
Season three premiere. Ofdensen comes back. That is all.
Not just coming back, but coming back in time to prevent Dethklok from signing a new contract with a corrupt record executive. Fans everywhere rejoiced.
Both of his encounters with Dr Rockzo.
"Put the boots to him. Medium Style."
Keep in mind the resulting ass-kicking was only Medium Style.
"Give him one more."
Say Nathan, what kind of music do you play?
"DEATH METAL!!!" *(Falcon Punch!)*
The best part about this is that Nathan doesn't even wait for a reaction or anything. He throws that punch the second he finishes speaking.
Pickles spends an entire episode reminiscing about parental issues with his father, whose last words to him were "You belong in a garbage can". When another character, who'd been ignoring him the whole episode, repeats that line, Pickles beats the crap out of him. Toki helps. That character was Murderface.
Dr. Rockso gets a handjob from Skwisgaar's mom and brags about it, while Murderface (who'd been trying to get one all season) and Skwisgaar watch...even if he did a powerslide over the Moral Event Horizon in the process.
Pickles gets a pretty awesome Big Damn Heroes moment at the end of "Rehabklok." He finishes the final step of his rehabilitation just in time to find that the drum machine that replaced him has kidnapped the rest of the band and threatens to kill them with its self-destruct mechanism. The machine locks Pickles inside, preventing his escape...and also trapping him with an entire table's worth of alcohol. After an internal argument with himself, Pickles decides to get drunk AND save the band. Which he pulls off fantastically with the hover drums that landed him in rehab in the first place.
The band later talks about how he played the entire show completely wasted and didn't miss a single note. Drumming or drinking, nobody does it better than Pickles.
"Doublebookedklok": 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.
Let's take a closer look at that. At just about every performance they've done up to this point, nine times out of ten, it results in a lot of people in the audience being killed by the special effects; and in this case, the Middle East teetered on the edge of an all-out war regardless. But this time? Dethklok, unofficial harbingers of mayhem and destruction (As Finland can attest), averted all that carnage and destruction. They saved millions of lives, and ended centuries of bloody conflict. In one of THE most unstable regions of the world.
Granted, the laser satellites' malfunctioning melted a lot of the ice caps and caused a lot of chaos across other parts of the world...but still. The target audience didn't suffer any casualties; and for Dethklok, that's an achievement.
Also, Nathan pronounced "As-Salam Alaykum" perfectly, while also providing the most metal intonation of that greeting, ever.
Real Life Example: A Dethklok fan was playing their music loud at his job. His boss' daughter told him "to turn down that vile music." He refused, and he locked his computer on a continuous loop of Dethklok. His boss didn't even care.
YMMV on that one, though. That could also be interpreted as simply an obnoxious person being obnoxious. Of course, it's also pretty obnoxious to think you can boss someone around just because they work for your father.
