Here's the best conclusion in my humble opinion:

Aang defeats the Fire Lord but is mortaly wounded in the process. After some final words to the people he loves, especially katara, whom he will express regret for never doing anything about it, he passes on. Azula will pop up and start wasting everyone, but Zuko would realize her evil and redirect lightning she shoots at him back at her. She will fall into some kind of dark pit or something because little kids can't take dead bodies just lying around. Zuko will still end up going to prison for his crimes, as will Mai and Ty Lee, until he has served his sentence, but he will be on the road to restitution, possibly with Iroh's help.
There is this big funeral for Aang. Everyone who ever knew the avatar, bumi, jeong jeong, and thousands of people who didnt' know him will show up. After the funeral, possibly led by Sokka, Katara or Toph, people start wondering if there will ever be another avatar after what Aang has been through. (getting zapped by azula while in glow-mode). Then at the end there will be some kind of little north pole baby shown or something who will move two or more elements with his mind. His parent's will be shocked,and somehow everyone will find out about it. Suki might suddenly pop up and she and sokka will stick together, but Katara will just be starring at Aangs tomb-stone forever, until Jet pops up and walks her home. Things will be bleak, but they've hit rock-bottom and the only way to go is up. Maybe some people don't like the idea of Aang dying. Let me just quote my favorite philosopher, the Green Goblin.

GG-"...I chose my path, you chose the way of the hero. And they found you amusing for a while, the people of this city. But the one thing they love more than a hero is to see a hero fail, fall, die trying...."

See if you say that I'm not crazy then I'll CALM down. That's how it WORKS!!!

Definately crazy. Still, she's only a close second next to Starreh. The painbow thing still bothers me...

oh

But you know, you ARE very crazy, there's no need to be sad.

since this is yet another duplicate thread by the new vaati... I'll quote myself from the first thread

don't really care to go into and excessive amount of details,

Aang
goes into Avatar state wiping out most of the fire nation capital while
nearly killing Katara and Sokka. Toph and Bumi own up and Bumi is
killed by Firelord Ozai. Aang goes super crazy and goes straight for
firelord Ozai (aang has actually learned how to fight now) Azula comes
in, Ozai, Zuko, and Azula try to kill Aang and Iroh jumps in front of
Azula's lightning bolt directed at aang (who isn't in the avatar state
anymore). Zuko loses it and attacks Azula and Ozai, Aang and Zuko fight
Azula and Ozai, Zuko gets taken care of real fast and Aang fights ozai
and azula at the same time alone. Ozai and Azula corner aang and they
make a lame speech declaring how the fire nation owns. All of a sudden
a lightning bolt hits Azula knocking her across the room dead and u see
Zuko standing there with his fingers smoking (he finally learned how to
use lightning) Zuko and Ozai duke it out while aang tries to help out
Sokka and Katara who have been leveled by Aang while he was in the
avatar state. Zuko pins Ozai up against the edge of a cliff and makes
some speech about the avatar and other things, he points to Toph who is
destroying a whole battalion of fire nation soldiers, points to Iroh,
Azula, and Bumi who are dead, and jus tas he's about to finsih off his
father, Ozai hits him with a fireblast and Zuko is pretty much
helpless. As ozai stands over Zuko and is about to kill him Aang
finishes off Ozai (there are many ways to do this, pick one).

There u have it, so in the end a happy ending with Bumi, Iroh, Azula, and Ozai all getting killed, so it's not totally cliche

i think that at the end the water tribe and a few other rebels and villagers will come down and have a gigantic battle . so the gAang with??fight against Azula, Mai Ty lee and Mr. Ozai with Zuko. However in the end while the other's got knocked out, the remainders will be Azula, Zuko, Aang, Mr, Ozai, , by this time zuko joined the gAang again?? and is fighting Azula while aang and ozai fight it out. Azula is unconcious, so Zuko, and Aang against Ozai. Then Aang faints and Zuko talks to Ozai about how he hated him for everything and the scar, and sad stuff abt the father not caring for the son and what Ozai did to Ursa, Zuko's mum. However zuko gets hit with a deadly blast. Then comes the cool bit, Aang wakes up and turns to Roku, and starts hitting Ozai with fire attacks, then turns to Kyoshi and bombards Ozai with earth attacks, and Aang finishes off?? in the avatar state , and hits Ozai with the water and Air attacks, And then Ozai is dead and Aang confesses his feelings for Katara. Ohh and Sokka isn't sure of whether to like Suki cuz he is scared of betraying princess yue, so the spirit of yue comes and reassures Sokka that she doesn't care as long as he's is happy and that she knows that she will stay in his heart forever, . Also Zuko falls in love with a girl who is also an outcast of the firenation ( pretend that she met him before and taught him some cool fire bending moves.)

Aw, you didn't include Toph... meanie...

Toph hater j/k

How can anyone hate this? (Darn, I haven't updated my signature yet.)
