The Siege of the North (Part 2) - S1-E20
Corrected entry: When Aang is talking to Koh, Koh says that the Avatar tried to kill him in a past life, 800 or 900 years ago. Later on in the show, when Aang is on the Lion Turtle, it is revealed that it was Avatar Kuruk who tried to kill Koh. Kuruk was the Avatar before Kyoshi, who was born 400 years ago, as was revealed in The Warriors of Kyoshi. There is a 400 year gap between those events that doesn't fit together. If Kuruk was 400 years old, it would contradict what is stated in Avatar Day, because there, they said that Kyoshi was the oldest Avatar, at 230 years old.
The Southern Air Temple - S1-E3
Corrected entry: When Aang goes into The Avatar State because he found Gyatso, statues and paintings of the previous avatars begin to glow all around the world, including the Fire Sage's temple. They act as is this was the first time, but Aang already went into The Avatar State before this point, when he thrown off Zuko's ship in the previous episode.
The Boy in the Iceberg - S1-E1
Corrected entry: In the scene where you see the children sliding down Appa's tail, in the close up shot it's leaning on the sticks. From far away it changes to lying on the ground, then close up again, it's back on the sticks.
Correction: Appa's tail was never leaning on the stick, if you look carefully.
Correction: Kuruk was the last full-realized Avatar before Kyoshi. But just like Aang was trapped in stasis for a century where the world had no Avatar, all kinds of things could have happened to delay the next Avatar's arrival. War or illness could have killed off an unrealized Avatar as a child, for instance. There could have been two or three incarnations that never became full-fledged Avatars. Maybe Koh's dates are a little off. He says 800-900 years ago; a hundred years is an awful big range of uncertainty. This is all conjecture, sure, because there just isn't enough information to support these claims. But so is this mistake's claim that it is impossible for Kuruk to have killed Koh since there is no where near enough information to support that either. If it were stated outright in the show that Kyoshi was born the very first autumn after Kuruk's death, then we'd have a mistake for certain. But it isn't, so we don't.
