Yen'Fay's "And now, we clash!" and "Here comes judgement!"
Any time a particularly well-timed Dual Strike or Support Block occurs can make you want to cheer.
Better yet, if you're lucky enough when facing a particularly tough enemy, you may be able to see a Dual Strike with two critical hits. Pairing up a Dual Strike with two of the better crit quotes makes it even more awesome.
Or if speed allows for two strikes from the attacking unit...and then the supporting one Dual Strikes twice. Almost makes you feel bad for the other guy.
The mechanics behind the Swordmaster skill Astra mean that, if a Dual Guard takes place on the initial strike, it will also happen for the other slashes during that attack. This means that the supporting unit makes the Dual Guard roll, it's possible that they'll be Taking the Bullet for their partner not once, not twice, but five, ten, fifteen, or TWENTY times in a row (the latter requiring the enemy to have a Brave weapon, go second against a foe slow enough that they'd attack twice normally), proc Astra every single attack), without taking a scratch. Even if they're a Priest or Mage, and only have cloth robes protecting them. BADASS.
Once the villains get big enough to have their own crit and Mastery skill quotes, you can get excellent exchanges. Nothing counters Validar's "this was all written" quite like Chrom's "anything can change."
Once characters start unlocking their Mastery Skills, max out their stats, and Pair Up with someone they have a high support with (especially if they're married), just about any single battle has a good chance of becoming this.
The entirety of the exchange between Cassius and Kjelle in Kjelle's recruitment paralogue. HAVE THEM FIGHT. You will be treated to the following:
Kjelle: If you believe in any gods, you'd better pray to them now!
Cassius: My, my. Aren't we confident?
Kjelle: I don't fear you, coward!
Cassius: Aye, I suppose not. Most fools assume that liars and sneaks like me are weak. They want us to be weak, see? They NEED it. It lets them hold on to the fantasy that right prevails in the end. Heh... They can think what they want. A cocky fool is an easy target. Truth is, in the end, it's the clever ones who always survive.
Cassius: Wrong, girl. Your master will have COMPANY!
Walhart, of all people, gives a pretty epic verbal smackdown to Raydrik if you have the two talk in the DLC Rogues and Redeemers 2. In summary, Raydrik suggests the two of them team up to take over the land, and Walhart responds with "And Then What?", and when he sees Raydrik hit an utter mental brick wall, he calls him pathetic, and that without vision, a conqueror he is not. And then he finishes it off with saying that a schoolyard bully with a stick could dream up greater ambitions than him.
Beat Rogues and Redeemers 3, and Ike will say that he's never fought anyone half as strong as you. This coming from a man who fought (and beat) Ashera, half of the creator of the universe.
Anna's Badass Boast during the side mission she's recruitable in. Reminder that before this the player had only met her twin sisters, who were all regular (if a bit cheeky) NPC merchants.
Anna: You know, prices aren't the only thing I can cut in two.
The icing on the cake is Grima's reaction. Seeing this incredibly cruel and evil demon once so smug in his invincibility and incredible power begin to visibly panic in fear of knowing he's going to die for real is very satisfying.
Bonus points if Avatar scores a critical when fighting Grima. "Checkmate!" is of course the best one, since it could be the blow that wins the whole game for you, but even simple lines like "Here's how it's done!" suddenly take on new meaning against the Avatar's Evil Counterpart.
"You're finished!" is also incredibly fitting for the situation.
And finally, nothing cinches ushering in a new future and ending something once thought immortal quite like "Time to tip the scales!".
It really seems like the Avatar's crit quotes were made for the Grima fight, and most likely? they probably were.
Scoring a critical with either Chrom or Lucina. "Anything can change!" and "Hope will never die!" are spot-on for the moment.
"I challenge my fate!" In my game, she then did so by putting a sword through Grima's head.
It gets absolutely hilarious if Frederick hits a crit on Grima, telling a god himself to "Pick a god and pray!" And very badass, too.
Even better, after recruiting them through the Bonus Box, the player can deploy every SINGLE lord from the previous games to fight alongside Chrom. While none of them speak, it feels pretty damn awesome to fight the embodiment of evil alongside characters like Sigurd, Lyn and Ike.
And then at the end there's a triple crowner, and since that in itself is awesome, it most fits here. After you beat Grima for good and your allies start expressing confidence that the Avatar will return, Lissa delivers this gem:
Lissa: You're right! He/She has to be out there somewhere... And we'll find a way to bring him/her home. Even if we have to search every open field in this whole stupid world!
Sadly offscreen, Lon'qu defending Lissa from a random band of assassins (including archers) single handedly during their A support, which is an impressive feat even when you're controlling him in battle.
There's a surprising number of "action-y" supports in this game, such as:
Female Avatar and Aversa escaping from a group of assassins by working together, in one of their supports.
Sumia refuses to let go of the beehive she found for herself and Gaius even when the bees have stung her all over, because she wants to help him to get honey that badly. Gaius, who until then was comically hostile to her, is extremely impressed by her Plucky Girl nature, and ends up giving her all the honey inside.
Henry's marriage proposal to Sumia is both this and a Crowning Moment of Funny, not to mention damn creative. What's best than proposing to the girl you like by switching bodies with her both to ride her pegasus AND to get her a perfectly fitting wedding ring?
Noire, one of the frailest characters in-story, manages to give Yarne enough inspiration and courage to become mentally and emotionally stronger. We're talking about a shy Ill Girl who is seen as a mix of Fragile Flower and Lovable Coward most of the time, but her A Support with him oozesSilk Hiding Steeland shows that she does not always need to relay on her Split Personality to get things done.
Yarne: You're fighting in the next battle?
Noire: I am.
Yarne: ...Ah. I see.
Noire: For all my faults, the others still trust me enough to rely on me...
Yarne: But aren't you scared?
Noire: Of course I am! Even now, my hands are shaking...
Yarne: Then why force yourself? Wouldn't it be easier to just stay here andó
Noire: It would, but I don't want to do what's easy. I want to do what's right... Yarne, if you don't want to fight, you don't have to. I won't judge you. I don't want to go out there either.
Yarne: Then why go?!
Noire: B-because we have to win this war, and it's time for me to make a stand! So, yeah. I'm scared, but I'm going.
The Plan of the Avatar as revealed in Chapter 23 is incredibly awesome.
Give the bad guy a a round of applause as well not Validar, but the Hierophant, who reveals himself/herself to be Grima from the Bad Future, who was able to take the Avatar as a host and followed Lucina to the past, and even though he wasn't able to possess the new Avatar, he was able to manipulate events just enough to use the Hierophant as a sacrifice to revive himself.
The Avatar's rather philosophical speech in Chapter 14, in which he tells Chrom that people aren't controlled by fate, but instead walk their own paths in life, strengthened by the invisible ties between them and others. Particularly good if you're playing a Male Avatar and have already achieved an A Rank Support with Chrom, as it comes across as something of a Meaningful Echo of the speech Chrom gave to the Avatar in that support.
Morgan also says something similar to his/her non-Avatar parent, suggesting that the Avatar still believed in those words even in the future. Though which future is up for debate, given Morgan's unknown origins.
This becomes yet another case if you recruit Morgan when Chrom is his father. Hearing the words 'invisible ties' from his son is one thing, but to hear those words again from his wife in chapter 14... you'll be forgiven for thinking that Chrom went into silence before the scene continues.
Emmeryn, who put the badass back in Badass Pacifist. Her back story alone is incredible. Not only did she ascend to the throne at the age of nine, but she undid her father's ugly legacy of religious genocide and turned Ylisse into the most beloved and peaceful nation on the continent. Let alone that in-game, she's absolutely fearless. Going back to a war-torn nation where her capture is nigh-inevitable, because she won't abandon the people she worked so hard to protect? Sacrificing herself to stop the entire ruling bloodline of her nation from being captured or killed? Emmeryn will do all that and more, and not even flinch.
Furthermore, consider that in Paralogue 20, girls from the village she's been staying at have been abducted. Emmeryn is one of them, but escapes and this is after stepping off the cliff and sustaining brain damage so severe that she lost all of her memories and has trouble forming complete sentences.
The Future Past 3 gives the possessed Avatar one. S/he continues to fight from the inside to prevent Grima from slaughtering Lucina and her friends, even after Grima insists that his/her spirit has been completely consumed.
The Future Past 3 gives one to Severa: Grima may have reduced her and her friends to 1 hit point, Grima may be gloating about having won, but she refuses to give in and lays down her life for Lucina and the future. Laurent and Gerome are so impressed that they join her.
Noire's introduction is downright fabulous. She begins in captivity by slave traders and stripped of her weapons, but as soon as she finds a bow & arrow, she undergoes a Split-Personality Takeover and starts mowing down her captors like a deranged juggernaut!
Even better is how there are several flying units on the map, so Noire not only gets to attack her captors, she gets to hit many of them for bonus damage. Too bad for them they had to imprison an archer, huh?
Tiki's recruitment Paralogue is this, since it's one of the few missions in the game where the enemy can easily back you into a corner even on Normal due to the fact that it is an Escort Mission, where you have to defeat every enemy while preventing them from killing the defenseless Tiki. What makes it harder than most other Escort Missions in FE is that the enemies will completely ignore you unless there's no other way to get to Tiki, and enemy reinforcements just keep on coming for several waves from all around you. By the end, it's perfectly possible to be seeing a huge mess of Risen surrounding your army as you hold them back as best you can while you wonder when in Naga's name will they tire of throwing themselves at you.
While some of the bonus paralogues fit into other categories, Paralogue 19: Irreconcilable Paths, is this in spades' A battle at a rain-swept promontory at the edge of the world map against enemies strong enough to actually challenge overlevelled characters (which you will probably have several of by now). Topping it off is the fight against Walhart who when fought in the main storyline was somewhat underwhelming after all the hype surrounding him. Here, he's far stronger (quite possibly on par with the final boss depending on difficulty) and gives an epic rant on his motives and beliefs before battling you, not to mention the fact that he has forced some of the strongest of the Risen (Lucina even remarks that they are on par with those of the Bad Future when Grima was at full power) to bow before his will. The only thing able to top this is the fact that if defeated correctly he joins your army, complete with unique class, weapon and a very good statline.
Henry, if he's Owain's father, gets a big one in their B-Support. After taking an arrow to the shoulder protecting Owain, he and Owain realize that they're surrounded. Henry tells Owain to run and says that he himself will stay behind to take care of it. Which he promptly does, with the implication that he absolutely tears his opponents apart, considering the wound he took for Owain before the battle is the only one he suffers. But what makes this stand out is the fact this scene is entirely unique to Henry. Every other potential father — the Avatar and Lon'qunote Who, remember, fought off an ambush of archers to save Lissa in their A-Support. included! — flee the scene with Owain; they tell him that it's an ambush, they're surrounded, and that they both have to run. Henry is the only father who was deemed powerfulnote and/or crazy enough to take on an entire ambush on his own, while injured... and win.
Bit of a minor one for Owain in a support with Lucina, seeing the problem with Falchion's strength being off just from a single glance. Lucina on the other hand didn't see the problem at all until it was pointed out to her.
Lon'qu and Frederick. When you first use them, they demolish whatever's in their path. They come fairly early (one being one of the first characters you even use) in the game too, and with weapons like the Silver Spear and Killing Edge, they could almost be considered overpowered (if weapons didn't break, that is). Even Chrom acknowledges Frederick's strength. In Chrom and Vaike's C support, Vaike bets that whoever loses must pull Frederick's pants down. Chrom promptly replies that Frederick would kick Vaike's ass if he were to pull them down. As for Lon'qu, the only thing that even fazes him is women. That explains why "Marth" could beat him.
Gameplay example. This troper had Lissa as a Sage paired up with a unit she hadn't Supported with yet take on one of the challenge maps. At one point, Lissa came under attack by three enemies because of of a miscalculation. During the first battle, she took 45 damage, HP going down by more than half, doesn't manage to kill her enemy but manages to dodge the next attack. The next, the enemy had enough attack power to kill her on the first strike, and would've almost definitely hit her at 94% accuracy when she procs Miracle then crits. Next enemy? She dodges his first attack then crits again, all at only 18% crit chance. End enemy phase.
Lissa: Well, that's that.
Further gameplay example. How do you know you are a certified, invincible badass? How about One-Round Killing Future Past Grima with your Avatar as a Wyvern Rider with a Brave Axe and the only needed assistance being a Galeforce unit you only have C-Support with? The Future Past III is super easy if you have a flying unit with the Pass Skill, maxed out stats, and have used Boots on this character, as well as Rally Heart and Rally Movement. All you need a Galeforce Unit to Pair Up with, and you will not have anything to worry about on this map. Unfortunately, Apotheosis is there to ruin your day....
In a case of Gameplay and Story Segregation, if Owain and Inigo's parents are married and they are recruited And their parents have maxed out stats and good skills equipped, they will be practically invincible during their epic momentin Future Past II, making all their worrying a little redundant and pointless.
If Gaius is her father, the Noire/Gaius support line. At C level, Noire has been cursed by her mother (again), so Gaius decides to give Tharja a piece of his mind. Which, as revealed by their B support, ended up by him being cursed, like what always happened when he will decide to defend her, so Noire starts worrying that nothing will ever change and that her trip through time was for nothing. Then Gaius gives an epic middle finger to destiny by remembering he was a master thief and stealing Tharja's curse implements while she was away, something that Noire said never happened, and Gaius uses that as proof that nothing is ever set in stone. Let's say Tharja did not appreciate it, but you can tell that Gaius was thinking "Worth It" the whole time...
In the Paralogue where Gangrel is recruited, having him face the boss nets this gem that signals the return of the prodigal asshole.
Gangrel: You can't kill a dead man, sweetheart. Now to feed YOU to the maggots!
As much of a Tear Jerker as Emmeryn's paralogue is, she still manages to pull off an awesome moment. Despite knowing that the Grimleal is after her, shewillingly leaves the village to sacrifice herself anyway. Even after the events of Chapter 9, it's clear that Emmeryn is still the same all-lovingdeterminator that she always was.
Basilio's not quiteLast Stand against Walhart after Chapter 17 has one in Basilio not only surviving Walhart's attack, something Walhart himself compliments him on, but the proceeding to land a Critical Hit on the Conqueror and knocking him down to roughly half his health despite having a 0% chance to crit.Not to mention his knowledge of the future that Lucina gave him allowing him to pull off an impressive Batman Gambit.
