The Ivory Tower is pretty much this all by itself; the accompanying music just adds to its majesty.
Falcor making his big entrance by rescuing Atreyu just as he's about to sink and has G'mork almost literally at his heel.
Atreyu's bravery when faced with the Great Stone Gateway. He's just seen a knight get vaporized trying to make it through. As he considers what to do, there's a long close-up on his face, as we see his fear slowly change to determination. And then... "I'm going to try it."
Also, Bastian shouting encouragement. "Be confident, Atreyu! BE CONFIDENT!"
Atreyu's ride on Falcor. Fantasia never looks more majestic than it does from Falcor's back.
Atreyu killing G'mork. "If we're about to die anyway, I'd rather die fighting! Come for me, G'mork! I am Atreyu!"
"I will not die easily. I am a warrior."
The absolutely mind-bending moment for any kids watching when the Childlike Empress tells Atreyu that not only has someone been watching his adventures this whole time, referring to Bastian, but other people have been watching him, while looking directly at us.
Bastian calling out the new name for the Childlike Empress.
The look on Bastian's face when the Empress convinces him to make his first wish. He thinks for a moment... and then he looks up with this badass smile that tells you exactly what he has in mind and he follows up by shouting "YEAAAAAAAAHH!" as he is seen flying on Falcor.
Bastian's second wish: giving the bullies their comeuppance with Falcor's help.
