Avatar : My Favourite Anime!!!

Water. Earth. Fire. Air. Only the Avatar was the master of all four elements. Only he could stop the ruthless Fire Nation from conquering the world. But when the world needed him most, he disappeared. Until now... On the South Pole, a lone Water Tribe village struggles to survive. It's here that a young Waterbender named Katara and her warrior brother Sokka rescue a strange boy named Aang from a cavernous iceberg. Not only is Aang an Airbender--a race of people no one has seen in a century--but they soon discover that Aang is also the long lost Avatar. Now it's up to Katara and Sokka to make sure Aang faces his destiny to save the tribe--and himself. Did we mention he's only 12?

Aang
Aang is a hero - a 12-year-old hero who likes to stir up trouble. Raised by Airbender monks in a temple hidden in the mountains, Aang is the last Airbender and the only known survivor of the Air Nomads. It's Aang's destiny as the Avatar to master all four elements - Air, Water, Earth and Fire. But he'd rather search for adventure than save the world. Though he's very spiritual, Aang doesn't like being known as the mythical Avatar or being the center of attention, he just wants to be a normal kid. Aang loves animals, especially his giant flying bison, Appa, and his pet winged-lemur, Momo. He's quick to take detours along his journey, much to the dismay of Katara and Sokka, and he's a master of getting himself into sticky situations. Luckily for all three of them - and the rest of the world - he's pretty good at getting out of them too.

Zuko
In the beginning, Zuko is an incredibly focused, teenage Firebender who bullies and intimidates everyone around him. He is obsessed by only one desire: to capture the Avatar. Zuko's greatest weaknesses are his arrogance and impatience. He believes Firebending is the most dominant art and can never be bested by Water, Earth, or Airbending. Zuko's teenage overconfidence makes him believe he's invincible. Zuko charges into conflict impulsively and without precaution. As the series progresses, however, Zuko develops compassion towards the nations he's terrorized. Ultimately, he renounces the Fire Nation and joins up with Aang to teach him Firebending.
