Aang

Aang is the main hero in the cartoon series Avatar: The Last Airbender.

Origin
Aang was a mischievous youth from the Air Temples. Amazingly, he mastered air-bending at a very young age; a sign that he was, indeed, the avatar. When the monks of the Air Temples reveal to Aang that he is the avatar, Aang reacts in a confused manner. Believing that Monk Gyatso, Aang's personal mentor and father-figure, would hinder Aang's training, they decided to send Aang away to the Eastern Air Temple to receive proper training. Aang refuses to accept his destiny as the avatar, believing it will tear him away from Monk Gyatso, and runs away with his sky bison, Appa. However, he is caught up in a terrible storm, and gets knocked deep underwater with his bison. Unconsciously entering the avatar state, he water-bends, freezing Appa, and himself, to save them from drowning. One-hundred years later, he is discovered by two Water Tribe residents, Katara, and Sokka. Later in a search to find Aang's earthbending teacher the three of them met Toph, Aang's friend and earthbending teacher. The four of them now have the mission to save the entire world from the Fire Nation.

Personality
Aang is a calm, fun-loving peaceful boy who like games and he wants to solve his problems non-violently.

Powers and Abilities
Being the avatar, Aang naturally has the ability to bend all four elements: air, water, earth, and fire. Aang is very special because he has great bending tallents. He can use all four elements at the same time. He have master air and he is one of the greatest airbeders of all times. He also invented a new airbending technique. He have mastered water too, as he is able to make huge tidal waves and bend the entire ocean without to any difficulty. As stated by Katara he had the reflexes of a waterbending master from the very start of season 2. He have mastered earth too as he could create a whole zoo by using earthbending. He knows also to firebend, but he hasn't mastered it as great as air, water and earth. In the final episode Aang combine all the four elements to stop to war by defeating Fire Lord Ozai.

Avatar State
In the Avatar State, the avatar's powers are greatly magnified, but at a cost. If the avatar is killed in this state, he or she will not be able to reincarnate into another life, and the avatar will, ulimately, perish forever.
