* Big Mac's first transformation into Thor, effortlessly fighting off the Ursa Minor he'd previously been fleeing from.
* Thor's first act of heroism in the story, [[CurbStompBattle curbstomping]] the Wrecker and saving Rainbow Dash's life.
-->"[[BigDamnHeroes I SAY THEE NAY!]]"
* Fin Fang Foom is wiping the floor with Big Mac/Thor, telling him he is a mere imitation of the real Thor, [[TheReasonYouSuckSpeech and unworthy of his power]]. Then he [[BerserkButton threatens Big Mac's family]], and Thor proceeds to go apeshit and kill him.
* Each of the other future Avengers gets one in their initial appearance:
** Spitfire's first use of her Firebird powers, defeating the MLP version of [[Comicbook/TheIncredibleHulk the Hulk]].
** Blueblood proving he really has changed, with his first act as Iron Pony being to save Rarity from Whiplash. [[spoiler: Turns out this was a SecretTestOfCharacter Rarity and Celestia set up for him, but he passed, so it counts.]]
** Caramel's first act with the power of Captain Equestria being to hunt down the Loki spy who'd attempted to sabotage the project and capturing him. Especially impressive for a pony who up till then had a dismal track record of getting ''anything'' done right.
* The Avengers managing to work together for their first real mission and defeat the Juggernaut.
* [[spoiler: StanLee]]'s RousingSpeech to Big Mac, bringing him out of his HeroicBSOD, is a combination of this and CrowningMomentOfHeartwarming. Hell, so is the fact that the author managed to give [[spoiler: StanLee]] a cameo, for that matter.
* Big Mac using ThePowerOfFriendship to restore his teammates' powers [[spoiler: after Loki perverted that same magic to remove them.]]
* Big Mac and Pinkie managing to trick Loki, allowing Big Mac to retake Mjolnir and Thor's power.
-->'''Thor''': '''LOKI! I WOULD HAVE WORDS WITH THEE!'''
* All of the Avengers vs Dark Avengers fights during the FinalBattle, but Captain Equestria's is especially notable for breaking through the [[MindRape Penance Stare]] through ''[[TheDeterminator sheer]] [[HeroicResolve willpower]]'', while giving a WorldOfCardboardSpeech to boot.
-->'''Captain Equestria''': '''''No! I will not give up! I will not give in! I am not a failure! I am Captain [[PrecisionFStrike bucking]] Equestria! [[PunctuatedForEmphasis And you! ARE UNDER! ARREST!]]'''''
-->'''Ghost Flyer''': [[ThisCannotBe I-IMPOSSIBLE!]] NOPONY CAN RESIST THE PENANCE STARE!
-->'''Captain Equestria''': Call me nopony then. Because I never give up. No matter what. Even if I know I'll just screw up again, I keep trying. Because every once in a while, I get a day like today. A day when I ''win.''
** The other fights are only slightly less impressive, as Firebird and Iron Pony manage to turn Iron Monger and the Red Skull's own {{Hannibal Lecture}}s back on them before defeating them. Iron Pony even gives his own WorldOfCardboardSpeech, though his somewhat lacks the "oomph" of the Captain's.
-->'''Iron Pony''': (''interrupting Red Skull's HannibalLecture about destiny'') Stop. That's not greatness. That's just vanity. I got the two mixed up before. But let me tell you something. I never did anything. All I ever did was [[PrinceCharmless sit around lazily, devour food, complain, and treat everypony like dirt]]. ''That'' was my destiny. To be a burden until the day I died, and then forgotten by everypony save those who hated me. And had I clung to that stupid, selfish destiny, I'd be dead now. Pierced through the heart by a piece of masonry, my entire life bereft of meaning. [...] But I cast aside that destiny. I cast aside my idiotic 'superiority'. I got down on my knees and begged a pony I had once thought beneath me, not even worthy of my notice, to help me. And now? I'm here. [...] So I've decided. If destiny means being a selfish bully, blind to the needs of those around me... I want no part of it!
** Big Mac's speech to Loki during their own fight, where he comes to terms with [[spoiler: being both himself ''and'' Thor, rather than sharing a body]], before defeating the GodOfEvil with ease [[spoiler: including rather easily overcoming his ISurrenderSuckers moment and finishing him off with his own spell.]]
* While he may be the BigBad, Loki still has his moments. First, when he reveals how he's manipulated the entire story up to that point to his favor; then, when he shows that he anticipated [[spoiler: Trixie's betrayal]] and deals with it; and finally, when he manages to [[spoiler: die happy, content that his death will mutate all of Equestria, creating the world ruled by magic he'd always wanted.]]
