Like Water for Avatar
My Avatar snippet series continues... you gotta love Youtube.
One of the coolest things about Avatar is that as the series goes along, the characters develop and grow stronger. Katara, the series' lead female heroine starts off as your usual sidekick (along with her brother Sokka) to the main hero, Aang. In many other shows, she'd probably stay that way forever- always a cheerleader or sideline support. But not here in Avatar. An aspiring Waterbender at the start of the series, Katara has little power or skill when we first see her. But towards the end of the first Season, she learns more stuff and DARN... becomes a force to be reckoned with in Season 2. The things she can do with water are simply awesome.
The clip above is from the later Season 1 episode, "The Waterbending Master", and has Katara challenging the somewhat chauvanistic Master Paku to a duel when the latter refuses to teach her since she's a girl. More amazing elemental action that is just a taste of the awesomeness that is Avatar.
