I'm not saying there one, but wouldn't it be pretty cool? I wonder what it would be about though? Maybe we could use this thread, if it's allowed of course, to make up our own??ideas.

I had an idea. How bout after all the fighting, they've finally defeated the fire overlord. The world is brought to peace. But Aangs, job isnt done. He must now watch out for the people of the world till his time is up. A old threat rises. A man, claiming to have known almost all the avatars in history, goes after Aang. He is acutally literally almost hundreds of years old. But Aang is confused as to how someone could achieve such a feat. Well, it could be this man, was around since the first avatar came to be. At first, maybe this guy, has self proclaimed himself as the most powerful warrior of existence. He then learns of people prasing the avatar. Jealously and grief overcome this man, as he tries to find this first avatar. He challenges him to a deadly duel, but alas, loses. He constantly trains and tries to increase his strenght more for a rematch. However, he is devastated upon studying about the avatar, that the avatar shall live many lives through reincarnations. Much despair came over him as he learned he could not rest until he defeats the avatar once, no matter what life it is. Unable to come to term with facts, he starts to go deranged, and obsesses about this even further. He then learns a ancient spell. This spell could allow him to be perserved as Aang was for 100 years straight. He decides that if he can't defeat him now, he shall wait patiently. He leaves the life of his loved one and family, sickening about his desire to defeat the avatar once. The warrior has gained all experience of over the many centuries it has been. He shall be very tough. I'm not entirely sure what the dangerous part of the plot would be , but hoped it be something like that.
