I was watching a Sozin's comet episodes today, and there was a shot of Iroh blasting the ba sing se wall, while boomy was earth bending the ground that the owl guys were standing on, toward the city, when i knowticed..

That the greatest masters of the 3 different elements were present in one place. Its kinda like the avatar in three different people, but 2 more because jeong jeong was there as well as piando, and no air bender.

So i was started to ponder who would win in battle between the owl and and Aang, with his bending skills still at the level in which he fought Ozai.
