The hero gets his own Moment of Awesome in the rematch, however - even though Jafar is just as powerful and seemingly just as unbeatable the second time around - by tricking him into wishing for even more power... which comes with some rather significant drawbacks. ("Itty-bitty living space.")
The best part is that Aladdin has the balls to mock him about it at the same time.
Aladdin: You got your wish...and everything that comes with it!
Pretty much any time Genie's on screen. Could also count as a Funny Moment and Awesome Music for his musical numbers "Friend Like Me" and "Prince Ali".
The "Prince Ali" sequence is particularly spectacular. This, my friends, is how you grant a wish with all the trimmings.
Another one for Aladdin: After Jafar's brilliantly intricate plan to do away with Aladdin seemingly succeeds, he mesmerizes the Sultan into allowing him to marry Princess Jasmine. When Jasmine states that she wants to marry Prince Ali (a.k.a. Aladdin), Jafar tells her the news, in his best fake mournful voice. Then, out of nowhere, we hear what may be the best line in Disney animated canon ever, if not the best line ever PERIOD.
Aladdin: Better check your crystal ball again, Jafar!
Aladdin then proceeds to march right in, grab Jafar's snakehead staff and smash it on the ground, freeing the Sultan from Jafar's spell.
Jasmine herself confidently wows Aladdin by showing just how quickly she can master the art of vaulting from roof to roof.
He has two others in the same movie: first, when he frees Genie from the crystal ball Jafar's trapped him inside (by dropping it from a great height to shatter on the floor, even while straining visibly at the weight); and second when, at a point of near-death, he summons up the last of his strength to kick Jafar's lamp into the molten lava below, killing him and saving the day.
The animated series, anyone?
Mozenrath: Well, I like a good laugh too. I'm laughing already.
In one episode of the animated series, Jasmine got brainwashed by one of the baddies into believing she was the "Scourge of the Desert". It worked...a littletoo well, and she spent 99% of the episode effortlessly kicking everyone's ass.
Mozenrath defeating the whole gang after Genie's been captured.
Aladdin winning his Battle in the Center of the Mind with Mozenrath with his spirit's own mystical power. Especially since he spends about ten seconds in awe that his spirit has magic and then jumps straight to "Cool, I have a laser", and instigating a Beam-O-War.
Mozenrath: That's not fair!
Aladdin: Since when do you care about fighting fair?
In "Destiny on Fire," Aladdin and Razoul team up to defeat Aziz. This doubles as a Crowning Moment of Heartwarming as they've come a long way from being bitter enemies to invaluable allies.
The King of Thieves
Jasmine punching out one of the forty thieves, complete with this line.
Jasmine: That was for ruining my wedding!
Iago's character 180 (well, maybe 150) change, from Chaotic Neutral scoundrel to reluctant hero to Not-So-Chaotic Neutral scoundrel, at the end of the Aladdin movies. Summed up well with his final line, when he throws in his lots with Aladdin's treasure-hunting father:
Iago: You're a good guy, Cassim. But not too good!
Instead of fleeing when the forty thieves break up the wedding, Iago actively defends the gifts from Cassim, wielding a vase like a bat. Greed was probably his main motive, but it still takes a lot of guts to stand up to a masked man several times your size.
This one is even better in Swedish where the last line is: "Say cracker and you'll never see the sun rise again!"
Sa'luk not only surviving what first seemed like a standard Disney Villain Death, but also killing a shark while in the water was pretty Badass.
Cassim finally getting the hand of Midas. With his cape turned to dazzling gold, the first thing he does with it is turn the whole temple gold.
During the 40 Thieves' raid on the wedding in the beginning, while Aladdin is facing the King, the rest of the gang starts making progress against the raiders. Then Genie steps in and single-handedly chases them off. His power may be reduced to semi-phenominal, nearly cosmic, but even Sa'luk didn't want to fight the Genie.
Sa'luk: Cassim said nothing about facing the powers of a genie!
To save his son's life, Cassim throws the Hand of Midas to Sulak, who catches it by the golden hand. Sulak proceeds to claim it's his, and also Aladdin's life now... but Cassim merely smirks a little; he knows he's already won.
It must be said that this, just like when Cassim caught the Hand with his cape (as mentioned above), is a sign of his guile - it's a good sign of how he took control of the thieves back then, and he proves it here because he knows that Sa'luk will make the fatal mistake of catching it with his hand (which most people will attempt, rather than using their brains like him). Suddenly it makes sense that the violent Blood Knight (implicitly) lost leadership from him, and it parallels his son's cunning defeat of Jafar in the first movie - we know where he gets his wits from now.
