9 'Avatar: The Last Airbender' Characters Who Also Appear in 'Legend of Korra'

The Legend of Korra, a sequel series to Avatar: The Last Airbender that debuted on Nickelodeon in 2012, will begin streaming on Netflix on August 14. But while The Legend of Korra is set in the same world as Avatar—a planet divided into four nations, each with a corresponding elemental power wielded by its population of "benders"—it takes place 70 years after Avatar Aang defeated the Phoenix King Ozai and opened a new era of peace.

Even though many of the characters from Avatar: The Last Airbender have died by the time of Korra's future setting, a surprising number survived to witness the rise of the new avatar, Korra. Here are nine Avatar: The Last Airbender characters who popped up in The Legend of Korra.

Katara

After the events of Avatar: The Last Airbender, Katara and Avatar Aang had three children together (one of whom becomes Korra's airbending mentor). After Aang's death, Katara trained the reincarnated avatar, Korra, in waterbending. Now 85 years old, Katara remained behind with the Southern Water Tribe when Korra left for Republic City—the primary setting for The Legend of Korra.

Toph Beifong

Aang's earthbending teacher, Toph Beifong, also survived into The Legend of Korra era, becoming Republic City's first chief of police before retiring to Foggy Swamp. Korra receives training from Toph in the show's fourth season.

Zuko

As Fire Lord, Zuko and Aang created the United Republic of Nations, healing many of the rifts between nations left after the Hundred Year War. By the events of The Legend of Korra, Zuko is 87 years old and has stepped down as Fire Lord. In his old age, Zuko continues to act as an ambassador for peace and an agent for the Order of the White Lotus, traveling the world on the back of his dragon, Druk.

Sokka

While Katara, Toph and Zuko are the only three surviving members of Team Avatar, several more Avatar: The Last Airbender characters appear in flashbacks, visions and memories, including Katara's brother, Sokka. He's dead by the events of The Legend of Korra, but the show reveals that Sokka represented the Southern Water Tribe on the United Republic Council and once rescued a baby Korra from criminals.

Aang and the Avatars

Not only are the avatars capable of learning earth-, air-, fire- and waterbending techniques, but they're also connected on a continuum of reincarnation, which means past avatars are sometimes accessible through meditation or vision. So while Aang died at age 66, he still pops up in The Legend of Korra. As Korra's previous incarnation, Aang advises Korra several times over the course of the series. Other past avatars seen on Avatar: The Last Airbender—including Avatars Roku and Kyoshi—also make brief appearances in Korra.

Iroh

Though he's already old in Avatar: The Last Airbender, Zuko's mentor and former Fire Nation general Iroh makes a surprising appearance in The Legend of Korra. Decades after the events of Avatar, Iroh left behind his mortal body and entered the Spirit World, where he opened a tea shop. He reappears as a Spirit World guide several times over the course of the series. Iroh also becomes the namesake for Lord Zuko's grandson.

Those six are the main returning characters, but there are a handful of additional cameo appearances from Avatar in The Legend of Korra.

Admiral Zhao

One of the more obscure returning characters in The Legend of Korra, Zhao was a former nemesis of Zuko's, who killed the Moon spirit in his mortal life, damning him to wander in the Fog of Lost Souls after. Driven mad, he is still wandering there, decades later.

Wan Shi Tong

Appearing in the form of a giant owl, Wan Shi Tong is an ancient spirit who watches over an immense Spirit World library that can sometimes be accessed through the mundane world. In Avatar: The Last Airbender, Aang and his friends visit Wan Shi Tong's library looking for a way to defeat the Fire Nation. It doesn't go well, since Wan Shi Tong objects to using knowledge in the pursuit of violence. But the spirit returns in The Legend of Korra, this time to aid Aang's granddaughter, Jinora, in her search for portals into the Spirit World. Wan Shi Tong's library is also the location of another cameo—this one a little morbid—when the owl spirit points out the decaying skeleton of Professor Zei, who stayed behind after Team Avatar's visit to the library.

While a handful of Avatar: The Last Airbender characters show up in The Legend of Korra, the two series has countless connections, including many characters who are the children and grandchildren of Avatar regulars. Even the son of the cabbage merchant—whose crops Aang accidentally ruined, repeatedly—makes an appearance in The Legend of Korra.
