Avatar The Last Airbender Book 1:Water, Episode 4
Episode 4, The Warriors of Kyoshi is another great episode.
I especially enjoy the character development for Sokka, the introduction of the Kyoshi Warriors, particularly Suki who is very charming and cool, and the exciting fights.
It's fun, funny, and charming, with plenty of excitement as well, which makes it a very good representation of this series in general. I love it and give it S tier and a 10 out of 10.
