Revy had already been set up as a maniac Guns AkimboDark Action Girl early in Black Lagoon but the moment that clearly established her true level of badassness was when Dutch casually asks her to take on several boats full of heavily armed pirates. By herself. Leaping from one to the other while they're bouncing along at high speed. Rock can only stare in shocked disbelief as she wipes out the entire fleet, finishing off the last one with a grenade from an M79 grenade launcher as it tries to get away.
Basically everything Revy does is emblematic of this trope.
Rock got his first Crowning Moment of Awesome in the second episode, when he comes up with the plan for torpedoing a battle helicopter mid-air — which is then pulled off, with Rock giving the helicopter the finger with a smile as the Lagoon sails on by. "You got FUCKED!"
This sentiment is echoed by Rock's VA, Brad Swaile, who claims this line to be his favorite in the series.
This is followed by Dutch's great line: "Amen, Hallelujah, and peanut butter." Both a Crowning Moment of Awesome and a Crowning Moment of Funny.
Also, during Fujiyama Gangsta Paradise, when he has the stones to stand up to Balalaika.
"There are two things to remember when you're begging for your life; one is to entertain the person who hold the gun, the two is to give them enough reason to be convinced. Now, you don't have fullfiled any of this two yet. Now, dance! What obligation do I have to save you?" "...You're mistaken. It's not an obligation. "Justice" is just means. I only have one reason: It's MY HOBBY." "Hobby?" "Yeah. If some folks enjoying dying in gutter, there also people with hobby like mine. I'm just the same with you."
Another one during Fujiyama is when he makes Chaka slip on the floor with cleaning fluid and then proceeds to bash the asshole in the head. With a bowling pin and a Precision F-Strike: "Fuck you!"
The time he defended himself from Sawyer the Cleaner's three-foot long chainsaw with a metal shelf.
Then there's the time he managed to piss Revy off mid-diatribe and, when asked what he wanted on his tombstone, replied very calmly, "There's no cure for a fool with a gun." And then, just as she fires, he shoves the gun out of the way and only gets grazed, showing his words actually had a point.
Also in the manga when he comes up with the idea to sink a huge ship using C4 and a harpoon gun.
As well as his plan used to stop Roberta's rampage in El Baile de La Muerte.
Roberta, an ex-FARC-agent-turned-maid, is basically the Terminator. But this is cemented when, after having busted out her shotgun umbrella on a group of thugs, she turns to them, curtsies...and lets a dozen or so grenades fall from her petticoats. Outside, the Lagoon crew watch the bar explode. Minutes late, backlit by flames...Roberta emerges, unscathed.
It says something where she's not only able to go toe-to-toe with Revy, but win as well.
The El Baile de La Muerte manga arc shows provides her with several Moments of Awesome, but the cake goes to the time where she stops Sawyer the Cleaner and promptly destroys her Chainsaw using her gun barrel. Then kicks Rotton the Wizard in the balls, through his groin protector, and she makes little Fabiola cringe in fear simply by talking to her about their master. And in the start of that scene, she catches Shenhua's throwing blade, and SNAPS IT WITH HER TEETH (while wearing a Slasher Smile from hell)! Eat your gun out, John RamboTerminator!
And we thought that was the best (or worst) of her.... watch until she arrives in Golden Triangle. To cut it short, she took out the whole army of Golden Triangle warlords with nothing but a musket and flintlocks. Yes. You read it. MUSKET AND FLINTLOCKS. In MAID DRESS.that Musket & Flintlocks is actually modified & loaded with SABOT rounds, capable of burning through body armor & steel like a hot knife through butter, but that just increase Roberta's awesomeness. HOW'S THAT for improvisation??!!
Chapter 15 of the El Baile de La Muerte she fires a Barrett M82 sniper rifle with attached grenade launcher ONE-HANDED. REPEATEDLY?!!!
Miss Fabiola Iglesias herself. She may not be on Roberta's level, but when she gets out of being held down by boot-knifing a guy in the balls, then cleaning out the bar in the same manner Roberta did before casually pulling a grenade launcher out the back of her dress (and even Revy had to ask "the FUCK is that?!" at this point) and blowing the reinforcements and their .50 caliber machine gun to hell. Not bad considering this was her FIRST real battle.
Also, the reaction Balalaika had while Hansel was dying. She didn't express any sympathy for the twins, but... "You don't even understand, do you? ... I'm... feeling a bit tired." Balalaika is a Badass for sure, even when she's not actively kicking it.
Or when she stops Revy and Roberta from continuing their fight to the death, prompting Dutch to say that the three scariest women on the face of the Earth were in a confrontation and he had no desire to get in the middle of it.
Or her confrontation with the leader of the Washimine-gumi. He attacks her; she easily grabs him, tells him — with a smile — that yeah, they could cooperate, but that is for pencil pushers; she just wants to rule. Then she snaps his neck, thus putting any lingering doubts about her evilness to rest.
Balalaika: ROCK. Translate, and make sure he understands every word. I'm gonna tell you the truth tonight. What I seek is destruction and domination. I don't care about anything else. I'm only interested in how much I can dance in the pit of Hell when it's all over. (Slasher Smile) See ya there one day. (Neck Snap)
Hansel and Gretel themselves have many moments that would be listed on this page if the awesomeness weren't trumped by the terror aspect. I mean, they're Blood Knights who do in fact, casually and giggling, take out a bar full of people without breaking a sweat, including some of the above-mentioned Balalaika's men (who, you recall, could fight and win World War III), and almost any other pair of people who sound turned on by the idea of everyone coming to kill them would be on this page, not to mention their successful Batman Gambit to divert almost all of the bounty hunters...the fact that they're maybe ten or twelve at the oldest transforms the awesome into freaky, though.
There's also them taking on an entire room filled with armed gang members and winning. Shortly afterward, Gretel has a brief gunfight with Mr. Chang, with both of them emerging unharmed (unless you count the deaths of Mr. Chang's men and his car).
The small Batman Gambit they used to get away from their pursuers (via bribing two local orphans to dress like them and take their places, using them as decoys and getting them killed instead of themselves) was rather smart, too. If pretty cruel.
Ginji Matsuzaki. Slicing bullets. Revy was still talking about this, hours later, sounding impressed, and the only reason Jumbo doesn't have more mention is because the mere idea of trying to list every single one of his Crowning Moments would make Your Head Asplode.
Of a lesser mention, the head of the Washimine group having the titanium balls to go after Balalaika with nothing but a sword. Yes, he failed, but seeing him trying to go down fighting was quite awesome.
Up to this point, it's been hinted that Eda is working as an undercover CIA agent. Chang has just gotten through telling Eda that his organization are neither allies or lapdogs of the American government, and that the only reason he's working with them is to get something in return. Eda turns it around instantly, by reminding Chang that, not only does she not represent a "holier-than-thou" mentality, but that all of the agencies like hers and the states themselves collectively are the United States; a hydra. To top it, Eda reminds Chang that, where he can bring gangs and companies to heel, Eda has the ability to bring entire nations to ruin. Not only is it awesome because it puts Chang in his place, it also shows who the truly dangerous people are in Black Lagoon.
Despite his foolishness and idealism, he's competent enough and is so far the only character who indulges in protection like bulley-proof vests; he may as well be an ordinary Red Shirt if he isn't Genre Savvy.
In the omake where everyone's telling ghost stories Rock's story was the one that scared everyone. Including Hansel and Gretel. It also frightened Balalaika so much that she asks Boris to accompany her to the bathroom.
The Gray Foxes deserve a spot here for not only surviving all Roanapur could throw at them and more, but also being the only thing in the series, more precisely in the OVA (in the manga this was not the case) to hurt Roberta in a significant fashion.
While Chang can easily out-Guns AkimboRevy (with infinitely more style), the real reason his spot here's overdue is because he manages to keep the peace between the other crime heads. (Read: the Columbians forcing and bungling their own agenda, the Italians who apparently have a tradition of antagonising everyone else, and Balalaika.) Without him playing the role of Only Sane Man, there's a good chance a typical meeting would end up sparking World War III.
