*Tarzan hesitates a moment, pushes the gun against Clayton's throat and (perfectly) imitates a gunshot*
Tarzan: Not a man like you! *breaks the gun*
The look he gives immediately afterward along with the score's Sting really finalizes the CMOA.
Tarzan's nameless parents? After being shipwrecked and washed up on a jungle island with their infant son, they decide to not moan or bitch about it and instead make a tree house that we all wish we could have built as kids. The kicker, the mother for a woman of that time actually helping the father with the heavy lifting instead of just doing the 'woman's' work. Keep in mind that all of this is taking place in the nineteenth century .
Hell, "Two Worlds" in general is awesome.
"Son of Man" was just awesome! Tarzan growing up, becoming a man, swinging from vines and surfing down trees!
Hell, the tree surfing in general. I wish I could do that!
"Son of Man" starts when little Tarzan vows to become the best ape ever. The first shot is of him failing to keep up with the gorillas without help. At the end, he's outpacing them thanks to his badass swinging and parkour skills. That's awesome stuff right there.
It's also where Tarzan stops trying to be exactly like the other gorillas, which he very clearly isn't, and starts thinking and acting more like a human — making weapons, swimming, fighting with wits and agility as opposed to brute strength, using his natural human agility to swing, tree surf and do parkour. He finally starts to get familiar with the second half of "ape-man."
"Two Worlds" reprise, specifically in the end when Jane and Tarzan swing out to the ledge, zoom out to see them and the beautiful jungle scenery, with Tarzan letting out his famous Tarzan cry!
Going on from that, there's the sheer fact that Jane can keep up the vine surfing and the swinging with Tarzan; he's been doing this for most of his life, while she's been a sheltered Victorian girl for most of hers.
It should be noted that Tarzan was likely going easy so she could keep up. That said, it was still impressive on her part.
How about Kala fending off Sabor while protecting baby Tarzan? She's more badass than Kerchak!
And she knows it too. When Kerchak goes slightly berserk against her (for defying him about getting rid of baby Tarzan), she not only doesn't move, she gives him a Death Glare.
To Kerchak's credit though, it took ten seconds of her glare before he relucantly gave in.
In the Son of Man montage, Tarzan climbs a freakin' waterfall!
On a meta level, the movie is a Crowning Moment of Awesome for Disney's animators, who were working with arguably their most complex character yet (Tarzan, who was drawn with total anatomical accuracy) and definitely their most complex scenery yet. The result? An incredibly fluid kinetic experience that's virtually flawless, featuring high speed movement where every single muscle stretched and flexes as it should and perfectly in sync with CGI backgrounds that look like paintings in motion.
Tarzan vs. Kerchak. To clarify, Kerchak is a silverback gorilla, well capable of tearing a human being in half with about as much effort as one uses to breathe. He is furthermore, at the moment, supremely pissed off. What does Tarzan do? HE PUTS KERCHAK IN A HEADLOCK AND WRESTLES HIM INTO SUBMISSION. I'll say that again: Tarzan (Human) beats Kerchak (angry Silverback Gorilla).
Kerchak deserves some recognition. At one point he did rescue a baby gorilla from the elephant stampede. He also ripped through his net and fought with the poachers for a moment before they tied him down.
