I will divide the points with each part of the final combat by counting the last 2 chapters (Sozin's Comet part 3 and 4
-Azula / Zuko / Katara: Azula's descent of madness is brutal showing all the problems that she had inside her only protected by the fear of people and her father but when her father abandoned her, she fell into the almost madness. The haiki kai of azula and zuko was definitely the best of the whole chapter, we would finally see the complete evolution of zuko fighting against azula who had lost almost all sanity, the animation the music all the haiki kai is the best fight of all the series, although also the participation of katara made the fight more interesting and the end of azula crying and screaming is brutal to finish the best fight of all avatar.
-Sokka / Toph / Suki: All this part is taken by sokka showing all his evolution and his great leadership, and toph and suki also stand out thanks to their abilities like, although obviously sokka is the protagonist.
-The order of the white lotus: The whole scene is very great where we finally see all the white lotus fight against the fire nation demonstrating all their abilities, and the end where iroh burns the flag of the nation is very good (not counting the scene of the hug of zuko and him).
-Aang vs Ozai: It is the weakest part of the whole special, for the simple fact that to be the final villain to be the one who generated millions of traumas to everyone, their fight is bad, aang and ozai never saw each other but They knew that their destiny was to face the avatar and the lord of fire, and their fight even though it had a brutal animation does not compare at all with the haiki kai of azula and zuko that is better musically, narratively, corrography, ETC, the fight of ozai against aang is literally: Aang runs ozai chases him but aang does not want to kill him receives damage from a stone on his back takes out the avatar mode chases ozai catches him and deactivates his powers, and voila THAT ANTI-CLIMATE! (The problem is that the OZAI is the final villain and he had a somewhat boring fight)
-The ending: The ending where zuko is put as the king of aang's winged fire represents that this has finally changed and times of peace will come (although in the comics they have more history) but when everyone gathers in the tea shop Uncle Iroh is very pretty and shows that they can finally rest a bit (even though the scene of aang and katara's kiss was a bit too much, I don't care with such a good ending).
-Sokka / Toph / Suki: All this part is taken by sokka showing all his evolution and his great leadership, and toph and suki also stand out thanks to their abilities like, although obviously sokka is the protagonist.
