Dr Sun has his moment right about here, wherein he casually indicates that he can easily take out the large battle-mech currently holding him in its clutches, and being piloted by the king of Europe. With his bare hands.
And Baron Wulfenbach's heartfelt sigh of relief upon Dr. Sun's being diverted from this goal would suggest that Dr. Sun wasn't just boasting.
He wasn't. It doesn't matter if you're ruler of Europe or not, when Dr Sun tells you that you need bed rest, he means it.
For that matter, a critically injured, nearly immobile Baron Wulfenbach somehow manages to get a giant Hospital Mech, piloted by two lovely nurses, up and running. A three-way combo of awesome, badass and pimp.
Another CMOA for Higgs is his ability to intimidate Tarvek. After seeing that jerk manipulate everybody and get away with it, it is immensely satisfying to see Tarvek lose confidence and actually fear somebody for once.
The end of the Tarvek gets sick arc. Higgs tricks Agatha into drinking water from the Dyne and Otilia/Der Kestle gives her an electric shock, turning her into this. Before she suffers from Power Incontinence, she splits her new found energy into Tarvek and Gil. Otilia is so impressed by this that she finally admits that Agatha probably is a Heterodyne.
Followed by a combination of awesome and funny that sums up all you need to know about the Heterodynes:
The best thing about this is that it feels like a Heel-Face Turn until you realise the only thing that has changed is the reader's perspective. Von Pinn is as constant as any construct, she is just protecting someone we want protected this time.
The Baron's majordomo Boris Dolokhov beats the location of the Jagergenerals out of another Jager. This actually impresses the generals enough to hear him out.
Dolokhov: We need to talk.
General Khrizkhan: Gospodin Dolokhov. Hod did hyu find us, hey?
Dolokhov: Your messenger told me.
General Khrizkhan: Vot? He vould not-
Dolokhov: Oh- not right away...
[tosses unconscious Jager at their feet]
General Khrizkhan: Whoo!
General Zog: Oho! You haz earned the right to a talk!
And a few pages later, Wooster's exit. While reading this, this troper inevitably heard the James Bond theme in his head!
Wooster's CMOA trumping of Boris gets better on reflection—they're on one of the dozens of auxiliary airships around Castle Wulfenbach, Boris (who was on the Castle) had to beat the location out of the Jaeger messenger, and since Agatha told everyone she was going into the Castle alone, sending Krosp, Zeetha, and Wooster away, Wooster's been, as far as we know, somewhere on the ground in Mechanicsburg. And he comes in through the generals' window. How did he even get up there in the first place? Steampunk Bond.
This comic shows us that a CMOA doesn't have to be huge or flashy or dramatic. It can be as simple as one word.
Agatha: Are you two fighting again? Gil & Tarvek: No.
Another (potential) one for Higgs. Zeetha has been stabbed by Zola, and the pink banshee is gloating that Zeetha wasn't as good as she thought she was. Higgs' response as he cradles Zeetha? Look upset, look mad as hell, and say this:
"I have lost my castle! My Muses! My town! My hand is revealed to those BLASTED! UPSTART! WULFENBACHS! You and Lucrezia have done nothing but destroy my life and my plans, and now you're trying to destroy the one bright spot left - AND THAT I WILL NOT PERMIT!(...) Oh, nononoNO, you do not "Give up!" YOU DIE!"
Barry Heterodyne got a new one just by existing. In this comic, when his name is brought up in a moment of Tempting Fate, both Zola/Lucrezia(?) and Anevka/Lucrezia realize what they just said and start to panic that he might show up. Keep in mind that this is the Other, one of the cruelest and most evil characters in the series and a candidate for overall Big Bad, and they're TERRIFIED that their brother-in-law might show up and ruin everything. Talk about establishing a rep.
Maxim has his in a tear-jerking moment that speaks deeply to any combat veteran. "Ve don't leave our own behind." Which becomes even more powerful in the final panel: Maxim gives his hat to Abner so that Lars can be given the funeral rites of a Jaeger.
Maxim: So ven hyu bury him...make sure he gots a hat.
Moloch von Zinzer has Fraulein Snaug, a bunch of tiny clanks, and some pulleys and leverage. He manages to put the HUGE waterwheel of Castle Heterodyne's Great Movement Chamber back into place.
Gil's third fight with Vole. Vole has just simultaneously beaten him and Tavrek while scolding them for talking during a fight and not taking him seriously. Gil hits him from behind, punches Vole in the face when he starts to talk, starts silently pummeling him with a chain of blows, and ends by putting a gun under Vole's chin and pulling the trigger three times. Too bad it's empty.
Tarvek manages to kill two of the Baron's questers effortlessly, then make his escape from the burning ship carrying, in order: Brenn's notes, the aforementioned (mostly) unconcious Action Girl, at least one adult waspeater, an injured Jaeger and any number of baby waspeaters. Oh, and he also manages to outrun a Hive Queen, while still carrying all of them.
deep within the enemies midst moved the Dreen, two unearthly, terrifying creatures garbed in dark, wide-brimmed conical hats and long, obscuring veils. They killed with but a touch, and they alone seemed to scare the Slaver wasps. Everywhere they drifted, a circle of emptiness opened around them as wasps desperately tried to escape.
Though the fact that, in a scene dedicated to Slavers brutally defeating a group of Wulfenbach troops, constructs, and clanks, they are still unscathed makes their badassery Fridge Logic.
Then, they showed up at the siege of Mechanicsburg:
Jaeger General: Yeek!
Jaeger General:Run! Der Baron iz not foolink around anny more! Doze tings iz unschtoppable! vorse-dey's scary!
(Zeetha and Violetta come across a scene of inexplicablecarnage where a unit of Wulfenbach infantry was laying down a withering barrage of suppressing fire on them a moment ago) Zeetha: Oh... Wow. now that- that's- That's something I'd expect the Castle to do! Castle Heterodyne:HELLO, LADIES!
THANK YOU FORSHOPPING INMECHANICSBURG! Castle pulls itself back together and unleashes every single clank and construct abomination within its bowels upon the Wulfenbach onslaught. The world was reminded just why Mechanicsburg is unassailable.
The Baron's Badass Boasthere is so awesome it makes the entire battle for the bridge of Castle Wulfenbach come to a dead halt.
A more subtle one on the same page. A random Wulfenbach Airman, not Higgs, proceeds to reduce a clank, made of metal, mind, to scrap with a single punch.
This strip reveals that Gil is in open war with the Other, the same entity which destroyed Castle Heterodyne in a single attack and went on to annihilate no less than fourty-three Spark houses. And Gil is holding his own.
