The producers of the show have named each season as a "book"; each of these books was named after one of the four elements in the show. Flashbacks also reveal events that happened before the show opened. In a flashback during "The Storm", the elder monks hold a private meeting with Aang to reveal his identity as the Avatar. Monk Gyatso, Aang's mentor and father-figure, insists that Aang be raised as a regular child. Nearing the end, the monks began to believe that Gyatso interfered too much, so they decide to send Aang to the Eastern Air Temple. Aang refuses to be torn away from his mentor; he writes a note for Gyatso before flying away on his bison. It is revealed in the first episodes of the show that a violent storm catches Aang and plummets him into the ocean during his escape. Aang then enters the Avatar State, unknowingly, for the first time to encase himself and Appa in a frozen air bubble. An image of this air bubble, resembling an iceberg, ends the flashback.

After 100 years in the frozen iceberg, the show opens when Katara and her brother Sokka free Aang and Appa in the first episode of the show. In the next episode, they all set off for the Northern Water Tribe, with intentions to find a waterbending master to teach Aang and Katara. In another episode, Aang meets his previous incarnation, Avatar Roku, informing him that he must master all four bending arts and defeat Fire Lord Ozai before the end of summer. Later, in the second season, Aang meets Toph Bei Fong, a blind earthbending master, who becomes one of his teachers. A couple of episodes later, Aang and his friends find out that a solar eclipse will occur before the end of the summer, rendering the Firebenders powerless. During the season finale, Aang battles in the underground caverns of Ba Sing Se. He is nearly killed when Azula strikes him with lightning, but survives thanks to Katara's healing abilities.

In the third season, Aang and his comrades gain a new enemy while traveling – an assassin hired by Zuko who firebends with his third eye. Aang and his remaining allies attack the Fire Nation capital in the tenth and eleventh episodes of the season, but are thwarted by Azula. In the following episode, Zuko has a change of heart and offers to teach Aang firebending. Aang accepts, despite the group's strong opposition. In "The Firebending Masters" Aang learns firebending with the help of the last two dragons.

During the two hour series finale, he struggles greatly about whether or not to kill the Fire Lord. After he sleepwalks into a forest, he speaks to four previous Avatars, seeking advice. Each tells him that he must kill the Fire Lord, albeit in different ways. After discovering that the forest is atop a swimming lion-turtle, and receiving advice from said lion-turtle, he prepares to confront the Fire Lord. Once Ozai arrives, Aang engages him in battle. After sparing Ozai when redirecting his lightning and then being backed into a corner, Aang releases his seventh chakra and enters the Avatar State. The Avatar State tips the battle in Aang's favor, and makes swift work of Ozai. Using a technique taught to him by the lion-turtle, Aang removes Ozai's ability to firebend, effectively eliminating the threat. Back in the Fire Nation capital, Aang is seen in monk robes, standing beside Zuko while he is appointed Fire Lord. He is later seen relaxing with his friends in Ba Sing Se.

Aang is a vegetarian, as shown in "The King of Omashu" when he refuses to eat meat, because the Air Nomads taught him that all life is sacred. Aang states a reluctance to fight in "The Spirit World (Winter Solstice, Part 1)"; Aang hopelessly negotiates with a spirit who is destroying a village instead of fighting. Due to his non-violent nature, he also shows ethical reluctance in killing Firelord Ozai, and eventually strips Ozai of his bending instead of killing him. In the show, Aang has a complex network of friends extending over all four nations.

Aang reveals in "The Storm" that he wishes he had been there to help his people a century ago, but would rather live a child's carefree life. Multiple times in the show, Aang demonstrates how much he cares for those close to him and his childish qualities, even to the point of deceiving others to keep the group together. In "Bato of the Water Tribe", Aang thinks Katara and Sokka might leave to visit their father. Aang hides the map showing their father's whereabouts and lies about having it in the first place.

In some episodes, he demonstrates flight abilities with airbending. One technique for this is to make a ball of air and ride on it, which Aang calls the Air Scooter. Other methods of flying include his glider, and Appa. In the last episode, Aang can also fly when he's in a ball of air.
