Eternal Wings and the Lost Ocean

• Kalas pulling a Big Damn Hero and rescuing Xelha from the Saber Dragon near the beginning of the game counts.
• While held up in Lyude's former home by his brother and sister. Lyude mournfully admits that he can't bring himself to harm his siblings. So his nursemaid pulls out a gun and readies to face them in his place.
  Almarde (fires off a warning shot) Next time I wont miss. I'm serious.
• When Melodia and Malpercio attack Mizuti's homeland. The Great Mizuti flies into a fury and unleashes a burst of energy so powerful that it nearly topples Malpercio.
  Mizuti: I...I will never forgive you! Never, never never!! (cue Super Saiyan- like outburst of power)
• Mizuti's tribe tries to get a powerful artifact guarded by their (significantly more powerful) ancestors. They fail, and then Mizuti shows up and demands that the ancestors wait while Mizuti makes sure everyone is okay...and then takes the ancestors on and wins.
• Gibari's Big Damn Heroes moment in Nashira, where he charges in and singlehandedly drives off a small horde of monsters.
• Savyna's introduction. Folon is kicking the party's collective asses and about to kill them, when suddenly Savyna appears and uses a fire-based attack on Folon and save the party's lives. She joins the party shortly afterward, and the attack she used to save them is one of her big finishing moves!
• Savyna and Azdar fighting the Palette Swap of Fadroh in the desert.
• Kalas' Unstoppable Rage after Giacomo stomps on and shatters his Winglet in the Celesial Alps. Complete with Theme Music Power-Up. Sadly, the ensuing fight is still That One Boss, still.
• Lyude finally standing up for himself and forcing the Eldritch Abomination that created the Phantom Goldoba to reveal it's true form.
• Xelha, who up until this point hadn't really done much other than serve as a foil to Kalas, stepping up and taking charge after The Reveal. She breaks out of the Imperial Fortress, rescues the other four party members from four Eldritch Locations, reveals herself to be the Ice Queen of Wazn, and finally invades Mintaka with only herself and her True Companions.
• Kalas tearing off his own Malpercio-granted Wing. It's undeniably painful, Melodia is surprised that he was able to do it at all with his own will, and that's when he finally returns to your team.
• And right after that, Mizuti pulls off a Big Damn Heroes moment by summoning images of five people (the Children of the Earth, of which he is one of), and Malpercio starts melting. While Mizuti does get shot down, it's still enough for Melodia to call for a retreat to Cor Hydrae for herself and Malpercio.
• The powers of the four End Magnus have failed to breach the Cor Hydrae's shield. The monsters around the various shrines are attacking the rulers of the nations. Everything seems lost... and then the power of the fifth End Magnus hits the shield, done by none other than Folon and Ayme of all people. With that power, the nations are able to breach the shield, starting the final level.

Origins

• The entirety of Vega. After the Heart-to-Heart scene, Guillo and Milly show up to break Sagi out and escape. After a long dungeon, you get confronted by Shanath and his machina arma. After fighting him and losing, Sagi powers up with the Guardian Spirit and cripples his machina arma, then fights him again and kills him. The fact that you can use The Apotheosis to trash him both times is just the icing on the cake.
  • The Heart-to-Heart scene by itself is jawdropping. It starts with Sagi returning to present time, chained to an iron block in an Imperial stronghold. He asks what you are, demanding to know why you never told him any of this. As you share secrets with him, he puts the pieces together and begins to sink into despair, fearing you will overwhelm and destroy him. You reassure him, and together you merge your hearts and unlock Sagi's true power.
• All three Big Damn Heroes moments in Tarazed. Heughes taking out a room full of machina, Nasca staying behind to keep a shutter open, and for the crowner, Valara swooping in on the Sfida to catch the falling Sagi and Milly.
• Sagi's Shut Up, Hannibal! to Shanath:
  Sagi: Go to hell, you son of a bitch! You hurt my mother!
