Opening sequence

The opening sequence is an introduction to the series Avatar: The Last Airbender and The Legend of Korra. It is played at the beginning of every episode.

Sequence
The sequence opens by showcasing the four elemental bending styles: waterbending, earthbending, firebending and airbending. The waterbending is performed by Master Pakku, the earthbending by Sud, the firebending by Azula and the airbending by an anonymous monk. The sequence then cuts to the map of the Avatar World. After that, Katara explains the beginnings of the Hundred Year War launched by the Fire Nation. Following this, Avatar Roku can be seen bending all four elements and disappearing in a gust of air when Katara states that the Avatar disappeared. Next, Katara and Sokka are displayed, then Aang, showing scenes from the first episode. The title card is shown immediately thereafter. The Chinese characters that appear at the top of the show's title card mean "the divine medium who has descended upon the mortal world."

Narration
Katara narrates the opening sequence. In the first episode, she states:

"'Water. Earth. Fire. Air. My grandmother used to tell me stories about the old days, a time of peace when the Avatar kept balance between the Water Tribes, Earth Kingdom, Fire Nation, and Air Nomads. But that all changed when the Fire Nation attacked. Only the Avatar mastered all four elements. Only he could stop the ruthless firebenders. But when the world needed him most, he vanished. A hundred years have passed and the Fire Nation is nearing victory in the War. Two years ago, my father and the men of my tribe journeyed to the Earth Kingdom to help fight against the Fire Nation, leaving me and my brother to look after our tribe. Some people believe that the Avatar was never reborn into the Air Nomads, and that the cycle is broken. But I haven't lost hope. I still believe that somehow, the Avatar will return to save the world.'"

Every episode after that, she says:

"'Water. Earth. Fire. Air. Long ago, the four nations lived together in harmony. Then, everything changed when the Fire Nation attacked. Only the Avatar, master of all four elements, could stop them, but when the world needed him most, he vanished. A hundred years passed and my brother and I discovered the new Avatar, an airbender named Aang. And although his airbending skills are great, he has a lot to learn before he's ready to save anyone. But I believe Aang can save the world.'"

On the first page of The Promise Part 1, Katara says:

"'Water. Earth. Fire. Air. Long ago, the four nations lived together in harmony. Then everything changed when the Fire Nation attacked. Only the Avatar, master of all four elements, could stop them, but when the world needed him most, he vanished. A hundred years passed and my brother Sokka and I discovered the new Avatar, an airbender named Aang. Although his airbending skills are great, he had a lot to learn before he was ready to save anyone. But from the first day I met him, I believed Aang would save the world. And you know what? I was right. With the help of his friends, Aang defeated Fire Lord Ozai and ended the Hundred Year War. Zuko, Ozai's son and our ally, became the new Fire Lord. Together with Earth King Kuei, Aang and Zuko promised to return the Nations to harmony.'"

Sequence


The show opens by showcasing the four most recent Avatars bending their native element: earthbending by Kyoshi, firebending by Roku, airbending by Aang, and waterbending by Korra. The bending shown by these characters is different than what has been seen before. Behind each bender is calligraphy similar to that seen in the original series' background. Then it shows a picture of Team Avatar, followed by a map of the Avatar World. After that, Tenzin explains the transformation of the Fire Nation colonies into the United Republic of Nations, before the picture zooms in on the capital: Republic City. A statue of Aang is then seen on an island in the bay, and it is explained how the Avatar accomplished many remarkable things in his life, his eventual death, and the Avatar cycle's continuity.

Narration
Tenzin narrates the opening sequence. In the first two episodes, he states:

"'Earth. Fire. Air. Water. When I was a boy, my father, Avatar Aang, told me the story of how he and his friends heroically ended the Hundred Year War. Avatar Aang and Fire Lord Zuko transformed the Fire Nation colonies into the United Republic of Nations, a society where benders and non-benders from all over the world could live and thrive together in peace and harmony. They named the capital of this great land Republic City. Avatar Aang accomplished many remarkable things in his life, but sadly, his time in this world came to an end. And like the cycle of the seasons, the cycle of the Avatar began anew.'"

In the following episodes, he says:

"'Earth. Fire. Air. Water. Only the Avatar can master all four elements and bring balance to the world.'"

In most episodes, Shiro Shinobi narrates events of previous episodes, similar to Roku's "Previously on Avatar" sequence. The sequence is shown with an effect similar to news-reels in the 1920s.

Trivia

 * Along the words, "Everything changed when the Fire Nation attacked", a line of firebenders is shown as they are seen in the series. However, the war began one hundred years prior to the first episode, when the Fire Nation's armor supposedly had large shoulder spikes and a faceless helmet, according to Chief Arnook.
 * Azula bends normal colored fire rather than her trademark blue fire.
 * The unknown monk airbending is the only character in the opening of Avatar: The Last Airbender who was not shown in either series.
 * In the opening of both series, the airbenders are the only ones who begin their respective bending sequence without having both feet on the ground.
 * In the opening of The Legend of Korra, Avatar Kyoshi is shown for the first time bending an element without using her fans.
 * Aang is wearing different clothes than the ones he wears in the actual series. These clothes are also used for his design in the "Who is Amon?" photo album on Nick.com.
 * Korra used a move similar to the one in the opening bending sequence during the semifinal match against the Buzzard Wasps.
 * In the extended version of The Legend Of Korra opening sequence in "Welcome to Republic City", in the picture containing the original Team Avatar, Katara and Aang are wearing their season one and two outfits and hairstyles, Sokka has his space sword (which he acquired in season three), and Zuko is wearing his season three hairstyle and outfit.
