Kamina's Big Damn Heroes against Deathwing, as well as the empowering speech he gives when he arrives:
"So bring your fire, 'cause it ain't got shit on mine! Bring your hate; I'm man enough to take it! Bring your rage, and I'LL STOMP IT DOWN WITH MY SPIRIT!! Cause I'm Kamina, of the DAI-GURREN BRIGADE!"
"... Is the meaning of pain nonsense now, bitch? It's easy for the guys on top to look down and say that us victims just whine and bitch...It's easy to not think about how it would feel to be in our shoes, what it would be like to not be able to control your own fate. That's what power does, power makes you complacent, makes you comfortable, makes you less able to move when you've gotta run. Now look at you, brought down by the mortals you called rats, weaklings, and ants that you had no qualms in crushing. Shall I now stop and listen to your complaints of foul play? No. No. No. No. No. No. No. No. No. No. No.They would just be the complaints of the defeated. Because you're afraid of those beneath you. Because you feed from our pain, you need our backs to build your power on. Because when that day comes when we decide to stand on our feet and destroy the heavens that torment us, you will not be ready for it. Your cornerstones need us to stay bowed and obedient because when we stand, you fall."
Chapter 10 through 11 is a giant deathmatch against Cyclopsis with the ancient zord being able to match the Rangers blow for blow due to it's adaptive ability. It's somehow awesome to watch Cyclopsis have the upper hand just from how badly he was beating the Rangers.
The Rangers mixing and matching their mecha in an attempt to confuse and throw-off Cyclopsis.
The Angel Groove Defense Force earning their promotion from Redshirt Army to Badass Army with the deployment of the Arc Troopers.
The Zilla Wars conflict is a five chapter (Chap. 20 to 24 to be specific) all-out war with the Rangers and Defense Force almost constantly on the rails. When you're fighting the clones of Godzilla led by Spacegodzilla and Decepticons launch a surprise attack while your already stretched thin, expect a lot of difficulty.
A few jewels within the Wars are as follows:
Noriko shoots her way out of the stomach of a Zilla that ambushed her and took her squadmates with her.
Unit 01 goes berserk for the first time in the series and utterly demolishes it's Zilla.
Almost immediately afterwards, Berserk Unit 01 is disabled in one shot by Starscream.
The Blue Eyes White Dragon Jet combines with Optimus' head and newly arrived Ultranus (aka evolved Ultra Magnus) to literally crash into Burning Crystal Godzilla's eye.
Lelouch geasses Reedman. I repeat, Lelouch now personally controls the most potentially dangerous Decepticon in the story.
Yugi mindcrushes Spacegodzilla. Nuff said.
The emergence of Mecha King Mecha Wrecka GAR. Possibly a case of a Spot Light Stealing Squad, but it's still awesome seeing just how much sheer power that this thing has.
Despite the heavy Butt Monkey status that she's been given, Misato still manages to improvise a plan to defeat Burning Crystal Godzilla that utilizes equipment, mecha and personnel that she is utterly unfamiliar with. She may have problems, but she's clearly a colonel for a reason.
Kaiba's "Reason You Suck" Speech to Gendo and Nerv in general when they try to force him to give back Shinji and an evolved Unit 01
"I have enough information to know that you didn't make up this organization to save humanity Commander Rokubongi. If you really gave a shit, then you would've done the intelligent thing and told your son about the giant purple robot before the angels attacked. I have to wonder...what would have happened if Shinji really was a pussy? What would have happened if he decided not to pilot the robot despite the emotional blackmailing? In fact, what if he wasn't in the country and couldn't get to Nerv in time? What if he had died in some freak accident? You'd be screwed and you'd be right to be screwed."
"What kind of military commander entrusts the entire crux of his strategy and the fate of humanity in the hands of a child who not only has no training in piloting mechas, but whom you'd abandoned for ten years and never even informed him about Nerv, the Angels or the mecha that you'd already predestined for him to pilot. Or maybe it was your wife who did it...whoever it was, it's fucking sick. You're not much smarter than my father, but at least his plan made sense and it did work...much more than he'd like in fact. But then Shinji came because he's obviously the Ned Stark of your circle, believing that his actions can draw out and be supported by the good in people...only to get a lance through his leg and have his head chopped off."
"Well guess what? This isn't Game of Thrones, you're not Tywin, your old hag isn't Cercei and the Colonel certainly isn't Arya."
The Moment is further cemented in the second half when he addresses Misato for her failure as a guardian to Shinji.
"Colonel...you're the type of person who makes all women look like useless weighted bi-polar vampires who live on by sucking off of other people. Hell! The only reason that you probably got your job was so that people would be too distracted by your huge breasts to notice how incompetent and unethical Nerv really is. You probably even know this, but you're so gun-ho for wiping out the angels cause they killed your dad that you don't even care. In fact, your self-esteem is so pathetically low that you'll even wear skimpy clothing around minors who are fifteen years younger than you and you constantly belittled your ward in order to run away from your own sense of self-worthlessness."
"You wanna talk about me being a self-loathing bitch? You're no better! All you do is flaunt around your money like it's a license to be a dick and waste it on stupid card games to compensate for your sense of self-pity-"
"I'm sure that you've got a great 'You suck and here's why you suck' speech. But it's honestly not gonna be anything that Yugi and his friends haven't ever tried to hammer into my head. And make no mistake, I like them and all...but they're losers. The only reason that they could say anything was because they legitimately had a strong friendship that I somehow got dragged into. When I heard them talk, I just crossed my arms and gave them the decency of listening with one ear before it all went out the other. You? You sicken me so much that I'm not even gonna give you that privilege. Instead, I'm going to shut you down before you get any momentum and utterly destroy you in the most unkind verbal way possible."
"And before you even start about my real parents and that I'm adopted...okay, we both lost our parents to giant pale ghosts...I'll give you that. But here's the difference between you and me. If my parents saw that I took my grief and turned it into the fuel which allowed me to become the president of one of the most powerful companies in the Earth's Sphere, expanded their trust fund into a gold mine large enough to buy a miniature country and still win the Nobel Award for Best Big Brother for ten years in a row...they'd be proud that they died horribly to save my life."
"But if your father saw what you are now, he'd blink at the sad waste of life you've become. Deuces."
