Waver standing up to Gilgamesh after he defeats Rider. The meek little boy with absolutely no chance of surviving more than two seconds stares down one of the Nasuverse's most powerful characters and declares his endless loyalty to Alexander. And Gilgamesh lets him live.
Gilgamesh: "I see. But boy, if you truly are a loyal subject, you have a duty to take revenge for your deceased King, do you not?"
In the anime, Ea, Enuma Elish, oh, Enuma Elish. It's not the same crap as it was from Fate/stay night. It's much more lethal and awesome. It was even locked using another sword before he finally decides to use it.
Video Description: "You cannot imagine the immensity of the f*#k that Enuma Elish does not give about the laws of reality."
The whole scene is one ginormous CMOA for the guy, what with his thousands-strong army charging at and annihilating every one of Assassin's personas in a barren desert that made them exposed targets.
To detail what happened: Assassin was actually eighty sneaky murderers, and Saber had declared a king must be alone. Then he summoned his Badass Army of True Companions (that includes not just Greeks and Macedonians, but also a contingent of the Persians he became famous for defeating) and his sandy battlefield, thus leaving Assassin no place to hide, inverting his usual numerical superiority and shattering Saber's idea.
And his duel with Kirei near the end. And his line when he shoots him.
"Yeah. And you're too much of a fool to understand."
Gilgamesh himself is a much more likable character in Zero. His turning of Kirei into a man who lives For the Evulz, forcing Angra Mainyu to submit to him, and his final words to Alexander after defeating him were incredible.
Gilgamesh: "Until the end of time, this world will be my garden. Thus, I can assure you. You shall never find this world tiring."
Getting Gilgamesh to respect him counts as a crowner for Alexander, as well.
The one about Gilgamesh and Angra Mainyu has to be elaborated on. Even though the outcome was obviously pretty bad for the world, what Gilgamesh did here was actually sort of heroic in its own, Blue and Orange Morality kind of way. And it gets even better with Avenger's Woobie status. Essentially, Angra Mainyu is the incarnation of everything bad about humans. Sins, negative feelings, you name it. It knows nothing but those thoughts. Only hatred and denial. Nothing else can exist within that black mud because it is immediately swallowed up. So it is left alone for all eternity with nothing but its loathing for the world and itself. But Gilgamesh defies that. His existence is so absolute that he can stand where nothing else can. And he tells Avenger that it's okay. That he will permit it to exist. He gives confirmation to something that is antithetical to the very concept of it. And he succeeds. He's practically comforting the devil at that point, in his own, strange way. So he's a hero alright. Somehow.
It also function as a Take That to those originally responsible for Angra Mainyu, as they put the blame for everything on one person so that they didn't have to shoulder the responsibility of their own evils. Gilgamesh rejects that because he, as the king, will shoulder the weight of the entire world, so there is no need for a scapegoat.
Gilgamesh: "The King will acknowledge it; the King will permit it. The King will bear the burden of the entire world."
It just wouldn't be Wave Motion Sword time unless they break up the word and start with 'EX—!
Irisviel has been kidnapped, is on the verge of death, and is being interrogated by Kirei while being held by the throat. Her response? She calls Kirei a coward, tells him that he has no chance to defeat Kiritsugu, and pushes Kotomine Fucking Kirei to the edge. Apparently old man Acht must have given her massive adamantium balls.
Kirei seemingly gets completely checkmated by Irisviel when she binds his hands with magical wire and ties him to a tree. What does he do? Snap the thing in half to break free. With sheer physical strength. No magic, no power-ups or assistance from anywhere or anything, just his own sheer concentrated strength and force. The best part would be his complete nonchalance throughout the whole thing, like what he's doing is as natural and normal to him as breathing and nothing to make a big deal about, total opposite to the powerful show-offs that tend to make up this series.
"In a way, it could be said that the women still underestimated the terror that was the Executor of the Church."
This scene was also a giant Crowning Moment Of Awesome for Irisviel. Every bit of her character we'd seen so far had suggested a devoted loving housewife, with only a hint of her badassness coming out when she was driving with Saber. What we'd seen about her magic before suggested that she was a healer and overall just a sideline character. But when Kirei starts coming she stands in his way knowing full well he is an Executor of the Church. Because she will not let him hurt her husband. She busts out some fancy wire work and stalls him long enough for Kiritsugu to do what he needs to do. The leitmotif that plays for her while she does this? Let the Stars Fall Down. The fact that she lost does not in anyway diminish the awesomeness of that scene.
The anime really made the not awesome scenes from the Light Novel into awesome. Lancer's curse while it's tragic, it become sort of awesome and the moment Kirei kills Tokiomi become epic, both mainly thanks to the fact it's visualized and also the camera and faces of the people involved (Lancer's rage, Tokiomi's surprise and Kirei's evil smile).
Lancer lifts the curse he put on Saber's hand to stop Caster from killing hundreds of people, then swats Berserker's hijacked F-15 out of the sky like it's nothing. Doubles as a Crowning Moment of Heartwarming.
Don't forget that Kiritsugu was attacking from Kotomine's blind side, since Kotomine's left eye was obscured by the blood from the bullet-wound to the head he still managed to mostly dodge.
From the same episode: "Daddy loves you, Ilya." *BLAM*
Remember, that episode was aired on what is Father's Day weekend in the states.
"Six billion people... or two members of my family. I will kill you. And I will save the world." He beat the Grail with its own logic... which was Kiritsugu's logic to begin with.
While it may be a Pet the Dog moment for Gilgamesh, getting himself spared after Rider's death was a pretty serious CMOA for Waver, especially when the light novel makes it clear that if he had shown the slightest hesitation or weakness, Gil would have snuffed him out like a candle and not given it another thought. This is the scene that shows just how much Waver has grown throughout the series; from being reduced to a gibbering wreck by a few well-chosen words from his former teacher to facing down the King of Heroes himself after said king just cut down Waver's own Servant in front of him.
Caster summoning the Nasuverse equivalent of freaking Cthulhu all the while delivering an awesome Blasphemous Boast
Caster: "Now once again we rise the flag of salvation! You who have been abandoned, gather here. I shall lead you! I shall rule you! The resentment and rage of we, the oppressed, shall reach to God himself! God in heaven, with word of condemnations I praise your holy name! Arrogant God! Cruel God! We shall pull you down from your throne!"
Alexander's heroic speech to Waver. He gets a lot of impressive speeches, but this one takes the cake. Basically, Waver is questioning his right to have such an awesome servant, saying he'd be better off with Assassin and Rider must resent him for having to be led by someone so small. In one grandiose speech, Alexander both confirms that he thinks Waver is a fine master, and someone he respects, and points out that his attempt at conquering the world was a Did You Just Punch Out Cthulhu?? moment, and he believes Waver is doing the same thing, punching out his own Cthulthu. This is, of course, right before the pair of them ride off to fight Caster's Cthulthu.
Rider: "Look at this boy, this is the opponent I’m fighting (points to a map of the world). Now draw a picture of us two, right next to this enemy. And do it to scale, that we may compare ourselves."
Waver: "That's not a compliment. That's an insult. "
Rider: "That's true boy. You are a fool, through and through. Your desires are beyond your abilities. “Glory awaits beyond the horizon.” In my day, that was one of life’s basic tenets."
Waver: "That's why you kept charging east, like a crazed maniac?"
Rider: "Indeed. I wanted to see Oceanus with my own eyes. Unfortunately, my dream never came true. Oceanus is still my final destination. A dream that never ends. Go ahead and laugh. Two thousand years later, and I still have the same dream. Every bit the fool as well. And so boy... a pact with a fellow idiot seems ideal."
