FLAWLESS. FUCKING. VICTORY. Kira, Athrun, Neo, and the rest of the Three Ships Alliance/Orb/Terminal, manage to defeat Shinn, Rey, Luna, Durandal, and the rest of ZAFT without taking a single casualty in the finale.
Shinn Asuka's own moment comes right at the end of the very first episode of Gundam SEED Destiny.
For those who don't like Kira, it was when he stabbed Freedom with Impulse's BFS. At the Super Robot Wars Z promo, this got one of the biggest cheers of the preview.
Pretty much that entire episode is a Crowning Moment of Awesome for Shinn. Mini-CMoAs include throwing his Gundam's shield in order to bounce a beam off it and hit the Freedom from an unexpected angle, splitting his mobile suit in half to avoid a saber strike by Kira, and when Kira does his signature move of chopping off the enemy's head and gun/sword arm, Shinn simply detaches the chest flyer, has it ram the Freedom, and then blows it up. Finally, there's the simple fact that Shinn pretty much called out the show's resident God-Mode Sue.
Shinn: "I'm the one who's going to defeat you! Here! Today!"
Bandai themselves acknowledged this CMoA in Gundam Vs Gundam, where all the Impulse's attacks come from this episode - the shield bank-shot, the Open Get evasion move, the Chest Flyer bomb, all reproduced faithfully.
Kira's return to pilot Freedom was pretty much awaited. Unlike his reluctant younger persona from SEED, Destinys Kira requests to fight to protect Lacus. He singlehandedly defeats all Coordinators sent to assassinate Lacus before all kill themselves
Episode 23. Kira disables several mobile suits (including minor and major characters') in his Freedom and uses all tactics in the book against most enemies while defending the Archangel. The thing is that he doesn't kill any of his enemies. Had he gone for the kill, it would look like a Kill 'em All episode because half of the cast would have died.
Kira does something similar in the battle at Crete. He goes to defend Cagalli when she is being attacked by Shinn which causes Athrun Zala to defend his underling. The two best friends once again start fighting but are interrupted by Sting Oakley. As soon as Sting attacks them, Kira gets close to him and destroys his Chaos Gundam using just Freedom's sword in few seconds. The same happens later when Kira defeats Athrun in a melee fight and destroys the Saviour in the process. He didn't even feel depressed for doing it unlike his younger self!
Kira saving Lacus and Andy from the Zaft base troops in episode 26 wasn't too impressive really (nobody was there who was even close to standing a chance so it was just another day at the office for him). However it's one of the only times we see Kira in action from afar, without dynamic camera shots tracking him and making his actions easy to follow. Kira bounces around like a pinball, making it impossible for the viewer to track him. None of the Zaft forces having time to blink let alone try to dodge him. Suddenly those scenes where it seems like the enemies are just sitting there letting Kira hit them makes sense. It's not random plot stupidity making them sit there wide open, they litereally have no time react before he's hit them.
As someone who did like Kira, and thought Shinn needed to grow up a little, I will always believe that Shinn (and the rest of the ZAFT team) got their CMoA during the Battle at Heaven's Base. It's one of the few times in series where Shinn is one hundred percent, no questions asked in the right (face it: it's tough not to be in the right when you're fighting Blue Cosmos, a group that's somewhere between the Nazis and the KKK). And what happens? He, Rey and Luna go after five Destroys. Luna takes one out on her first flight in the Impulse. Shinn and Rey take down two apiece, and Shinn in the process, finally settles the score with Sting, probably the least sympathetic and most genuinely evil member of the Extended. And on top of it, we get to see Djibril's face as he realizes that it's all over. Beautiful, just beautiful.
This troper firmly believes that Shinn's true CMoA comes in episode 12. A massive mobile armor has apparently disabled Shinn's mobile suit, has blocked everything the Minerva can throw at it, and is now moving in for the kill, backed by an entire fleet. It looks like the Minerva is pretty much boned...until Shinn wakes up. Flying into an Unstoppable Rage, Shinn rejoins the battle, destroys the mobile armor and proceeds to sink six of the enemy ships, using only swords.
Right after Kira acquires the Strike Freedom and launches from the Eternal, he faces a few ships and numerous mobile suits. He proceeds to defeat and disarm 25 of them without taking any damage. In two minutes.
Another Strike Freedom CMOA was Kira's move during his fight with Shin in the Destiny at ORB. Shin readies his BFS, and goes to bisect Kira's MS Vertically, and Kira CATCHES it, with his HANDS. Badass Indeed.
This troper feels obligated to point out that the Astray Manga's Rondo Gina Sahaku one-ups Kira. by pulling that move twice: The first time while piloting A GRUNT. The second time is even more awesome, as he catches the Red Frame's blade IN BETWEEN TWO FINGERS, then uses the bottom edge of his shield to break the blade clean in two.
The real difference isn't that it's a plasma blade, but that it is also meant for slicing through large ships like they were nothing. Meaning had Kira not caught it like he had, it would have easily sliced through the Strike Freedom.
Neo Roanoke has been sulking around the Archangel for several episodes when, preparing to do battle with the Minerva, Murrue gives him a Skygrasper and drops him off on land, explaining that keeping him on board any longer would just be needlessly endangering him. In the midst of the following ship-to-ship battle, what should appear out of nowhere to assist the Archangel but that same Skygrasper with Neo at the controls, shocking Murrue by dropping Mu's old Catch Phrase: "make the impossible possible."
In fact you can pretty much just say everything Neo does after his Heel-Face Turn; his first meeting with Murrue ends with him giving her a pimp pickup line.
In particular using the Akatsuki to block the Minerva's Positron Blaster cannon, in a repeat of Mu's Heroic Sacrifice... Minus the sacrifice part this time.
And even before his Heel-Face Turn Neo gets some amazing moments. Taking on Shinn and Rey at once? In just a Mobile Armour? And not only surviving, but fighting them to a draw? The Neo persona may be pure evil, but there's no denying how Bad Ass he is!
Lacus gets one in episode 43 when she interupts Meer, who is pretending to be Lacus and making a broadcast that had interupted Cagalli's broadcast about the war with Logos. The look on Durandal's face when he sees the real Lacus is priceless.
Stellar is mainly known for being childlike, but it's worth remembering that when she isn't acting adorable, she's a TykebombSuper Soldier. The best example of this has to be the first episode, where she leaps into a group of six ZAFT soldiers, holding a knife in one hand and a submachine gun in the other. She's killed five of her opponents by the time the first one's body hits the ground.
In episode 31, Stellar gains her full pedigree as Woobie, Destroyer of Worlds when she's given the Destroy Gundam. A massive ZAFT force, including dozens of mobile suits and a land battleship, sortie and lob everything they have at her. Stellar brings up the Deflector Shields and all their railgun slugs, missiles and particle beams splatter against the barrier like snowballs. Stellar's turn: she fires one shot with the Destroy's big guns, atomizing the battleship, the ZAFT mobile suits and a large chunk of the city behind them.
Stella's teammate, Sting, proves that the Destroy in general is awesome. During the battle at Heaven's Base, the EA are getting their backsides handed to them by ZAFT. Than Sting and his new team sortie in five Destroys and proceed to reduce the entire fleet to rubble. Only the arrival of Shinn, Luna and Rey saves ZAFT from total disaster.
Meyrin Hawke has a more subtle but effective one when she indy ploys Athrun's escapade, resorting even to a Modesty Towel to make sure her idol and friend wouldn't be caught in her house.
An explanation is needed for this one. The aforementioned Meyrin Hawke is a Bridge BunnyNa´ve Everygirl, who is suddenly caught in a situation way over her head when Athrun comes up to her room and asks her for help since he's being targetted by assassins. She doesn't hesitate to hide him in her bathroom, wraps self in a towel and go face the soldiers seeking for Athrun, who could perfectly throw her around and go check on her living space. And yet she manages to convince them to not do so, fooling them into thinking she's alone and just fresh outta the shower. For a teenager who's more often than not in the sidelines, that's pretty badass.
Also Athrun's escape deserves more attention. This is a single man trapped on ZAFT's largest surface base on high alert (and it's in flippingGIBRALTAR), targeted by ZAFT MPs, and with only Meyrin helping him out, he succeeds. (Yes, he does get downed by Shinn, but that was after Athrun had escaped.)
During the battle to prevent Junius 7 from being dropped on Earth, Yzak, Dearka, and Athrun manage to severely tear up Chaos, Abyss, and Gaia with their ZAKUs, putting the other characters who were fighting them to shame.
And to get there, she goes on a rampage through the ZAFT lines, survives Shinn (well, she stays alive long enough for Kira to get there) and essentially turns the battle around by herself. Goodbye to The Load, hello Action Girl. Did we mention that she's a Badass Normal to boot?
Kira's Big Damn Heroes moment is awesome in its own right. From Shinn's near panic attack at seeing the Strike Freedom, to the way that he and Cagali practically turn the battle around, it is epic.
Athrun launching in the Infinite Justice for the first time moments later. He helps Kira and Cagalli protect Orb from ZAFT, including the crew of the Minerva, ably fending off Shinn and the Destiny. The kicker? He had a bigass chest wound at the time. Hell, he even passed out when he landed!
Anything Gilbert Durandel does in the series is awesome, but his personal CMOA would probably be calling out LOGOS on international television. After spending episode after episode getting angrier and angrier at Djibril its just awesome to see how Durandel's speech nearly gives him epilepsy
Chairman Durandal: Thank you, Djibril. Goodbye and good riddance.
Any of the few scenes with Yzak and Dearka back on the battlefields. Between their epic tag-team moves, and destroying Gundams and Mobile Armors in epic Mook Suit, some custom, the viewers can't help but to grin as they are reminded why these two guys have always been awesome. Even Shinn comments in agreement during the Battle of Junius 7.
Not to mention their last minute Heel-Face Turn wherein they completely screw over Durandal by not only defecting, but taking a huge portion of the ZAFT fleet with them.
ZAFT's response to the advance of the "Peacemaker" force on their homeland? They deploy the Neutron Stampeder, which blasts the entire attack force and their supporting ships to bits with their own nukes.
In Stargazer we have former EA major Edmond Du Clos taking out a ZAKU in one on one combat. With a tank. It's the only time in the franchise that it's ever happened, and it's awesome. There's also the final showdown between Selene and the Stargazer and Sven and his Strike Noir, in which Hot Scientist Selene, who had seemed like a Distressed Damsel up to this point, manages to battle Sven, Ace Pilot and killing machine to a draw.
Remaster has the new episode 39 where Kira saves the Eternal with the Strike Rouge (now sporting the remaster's new Ootori pack). Where as originally he only fired a few shots and then was disabled trying to block a cannon shot, causing Andy to grab his rifle and tell him to go get the Strike Freedom (leading many to assume his skills has grown weak and he was only effective with a powerful Gundam) here he disables a Zaku before being in visual range (originally he just distracted it) uses missiles as a smoke screen to get past the fleet. Tosses Andy his rifle (as opposed to Andy taking it) and proceeds to unload with the Ootori's cannons. When the shot that disabled him originally is taken, instead of tanking it himself he ejects the pack into the shot, after drawing the anti ship sword and proceeds to pin the Zaku with vulcan fire before disabling it, and managing to block a surprise shot from behind which only destroys his shield and arm, before tossing the sword through the Zaku's head. Then he goes to get Strike Freedom as he's out of weapons but it was a much better end to the Strike (which is never shown again) then it orignally had, AND it shows Kira's skills are still sharp. To be honest it kind of upstaged the SF's debut,which was unchanged.
