The Avatar: The Last Airbender voice cast helped turn Nickelodeon’s animated fantasy series into one of the most recognizable animated shows of its generation. From Zach Tyler Eisen’s Aang and Mae Whitman’s Katara to Dante Basco’s Zuko and Mako’s unforgettable Uncle Iroh, the English voice actors gave the characters personalities that continue to resonate with fans.
But there is an important distinction for anyone searching for the Avatar: The Last Airbender cast today: the original animated series and Netflix’s live-action adaptation have completely different casts.
This guide focuses primarily on the original animated Avatar: The Last Airbender voice cast, including the actors behind Aang, Katara, Sokka, Toph, Zuko, Iroh, Azula, Appa and Momo. It also explains how those performers compare with the actors playing the same characters in Netflix’s live-action adaptation.

Who Voices Aang in Avatar: The Last Airbender?
Zach Tyler Eisen provided the English voice of Aang, the 12-year-old Air Nomad who discovers that he is the Avatar after being frozen in an iceberg for a century.
Aang’s character required a difficult balance. He is playful, energetic and often immature, but he is also carrying the responsibility of ending the Hundred Year War and restoring balance to the world. Eisen’s performance helped maintain both sides of the character without making Aang feel like a typical fantasy hero.
The animated Aang voice actor was especially important during the show’s more emotional episodes, when Aang was forced to confront the destruction of his people and the enormous responsibility attached to being the Avatar.
Aang’s journey eventually takes him through all four forms of bending — Air, Water, Earth and Fire — as he prepares for his confrontation with the Fire Nation.
Who Voices Katara in Avatar: The Last Airbender?
Mae Whitman voices Katara, the Water Tribe waterbender who becomes one of Aang’s closest friends and most important allies.
Katara begins the series with limited experience as a waterbender, but her abilities develop considerably as she travels with Aang and Sokka. She also becomes an emotional anchor for Team Avatar, often balancing Sokka’s humor and Aang’s impulsiveness.
Whitman’s performance gives Katara a mixture of determination, compassion and frustration, particularly when the group faces the consequences of the Fire Nation’s war.
For viewers searching for the Katara voice actor, Mae Whitman remains one of the most recognizable names associated with the original animated character.
Who Voices Sokka in Avatar: The Last Airbender?
Jack De Sena voices Sokka, Katara’s older brother and the non-bender of the original Team Avatar.
While Sokka initially relies heavily on humor and sarcasm, his character develops significantly throughout the series. He becomes a capable strategist, warrior and leader despite lacking bending abilities.
That progression is one of the reasons the Avatar The Last Airbender characters work so well as an ensemble. Sokka is not simply there to provide comic relief; his intelligence and tactical thinking repeatedly help the group survive situations that cannot be solved through bending alone.
De Sena’s comedic timing also gives Sokka some of the show’s most memorable lighter moments.
Who Voices Toph in Avatar: The Last Airbender?
Michaela Jill Murphy, credited as Jessie Flower during the original series, voices Toph Beifong.
Toph is a blind Earthbending prodigy who joins Team Avatar during the second season. Despite her young age, she is already an extraordinarily powerful earthbender and develops her own unique way of sensing the world through vibrations in the ground.
Toph’s blunt personality immediately changes the dynamic of Team Avatar. She is confident, sarcastic and fiercely independent, often refusing to treat her blindness as a weakness.
The character also became one of the most important additions to the original Avatar voice cast, with Murphy’s performance capturing Toph’s rebellious personality while still allowing her more vulnerable side to emerge.
Who Voices Appa and Momo?
One of the most interesting members of the Avatar: The Last Airbender voice cast is Dee Bradley Baker, who provided the vocal performances for both Appa and Momo.
Unlike the human characters, Appa and Momo do not speak conventional dialogue. Their personalities are instead communicated through expressive sounds and vocalizations.
Appa is Aang’s flying bison and his closest animal companion, while Momo is the mischievous winged lemur who becomes part of Team Avatar.
Baker’s performances make both animals feel like genuine characters rather than simple sidekicks. Appa’s emotional importance becomes particularly clear as the story progresses, while Momo frequently adds humor to the group’s adventures.
Who Voices Zuko in Avatar: The Last Airbender?
Dante Basco voices Prince Zuko, the exiled Fire Nation prince determined to capture Aang and restore his honor.
Zuko’s story is one of the most complex character arcs in the animated series. He begins as an antagonist pursuing the Avatar but gradually becomes one of the most important figures in Aang’s journey.
Basco’s performance allows Zuko’s anger, insecurity, frustration and eventual growth to develop naturally across the series.
The Zuko voice actor also helped make the character’s relationship with Uncle Iroh particularly memorable. Their relationship becomes increasingly important as Zuko questions the expectations placed on him by his father and the Fire Nation.
Who Voices Uncle Iroh?
Uncle Iroh was originally voiced by Mako, whose performance became one of the defining elements of the animated series.
Following Mako’s death in 2006, Greg Baldwin took over the role for the third season and later continued voicing Iroh in the wider Avatar franchise. Iroh is the former Fire Nation general and uncle of Zuko. Although he is introduced as a relaxed and often humorous companion, his history and abilities reveal that he is far more formidable than he initially appears.
Mako’s voice gave Iroh a distinctive warmth and calmness, while Baldwin continued the character’s role in the final season. The two performers are therefore both essential parts of the history of the Avatar: The Last Airbender voice cast.
Who Voices Fire Lord Ozai?
Mark Hamill provides the English voice of Fire Lord Ozai, the ruler of the Fire Nation and father of Zuko and Azula.
Ozai is largely presented as a powerful and intimidating figure throughout the animated series. His relationship with Zuko is particularly important because much of Zuko’s early motivation comes from his desire to regain his father’s approval.
Hamill’s extensive voice-acting background made him a natural fit for a character whose presence needed to feel threatening even when he was not physically on screen.
Who Voices Azula?
Grey DeLisle voices Princess Azula, Zuko’s younger sister and one of the most dangerous firebenders in the series.
Azula is exceptionally skilled at firebending and is also a highly capable strategist. Her blue flames distinguish her visually from other Fire Nation characters, while her personality makes her one of the most intimidating antagonists in the story.
DeLisle’s performance captures Azula’s confidence and precision while also revealing the character’s increasingly complicated emotional state.
Azula’s relationship with Zuko and her father is central to her character, making her much more than a conventional villain.
More Major Avatar: The Last Airbender Voice Actors
The original series featured a large supporting ensemble beyond Team Avatar.
Jennie Kwan voices Suki, the leader of the Kyoshi Warriors and one of Sokka’s closest allies. Cricket Leigh voices Mai, while Olivia Hack voices Ty Lee. Both characters become important members of Azula’s group.
Jason Isaacs voices Admiral Zhao, an ambitious Fire Nation commander whose pursuit of Aang creates several major conflicts.
Crawford Wilson voices Jet, the leader of a group of freedom fighters whose methods create tension with Team Avatar.
Johanna Braddy voices Princess Yue of the Northern Water Tribe, while James Garrett provides the voice of Avatar Roku.
Other recurring performers include Richard McGonagle as Bato, Andre Sogliuzzo as King Bumi and Hakoda, Michael Dow as Haru, and Jen Cohn as Ursa.Together, these performers helped make the world of the animated Avatar The Last Airbender feel considerably larger than its central group of heroes.
What Happened to the Original Avatar Voice Cast?
The original Avatar voice actors went on to pursue different careers after the animated series ended.
Mae Whitman continued working extensively in television and film, while Dante Basco remained closely associated with Zuko and the wider Avatar franchise. Dee Bradley Baker continued his prolific voice-acting career across animation, video games and other projects.
Grey DeLisle also became one of the industry’s most recognizable voice performers, appearing in numerous animated productions.
The original cast remains closely connected to the show’s legacy because the performances continue to define how many viewers hear these characters in their heads.
Original Avatar Voice Cast vs Netflix Live-Action Cast
The biggest source of confusion surrounding Avatar: The Last Airbender cast searches today is the existence of Netflix’s live-action adaptation. The original Nickelodeon series is an animated production, meaning performers such as Zach Tyler Eisen, Mae Whitman, Jack De Sena and Dante Basco provide the voices for the animated characters.
Netflix’s adaptation uses a completely different ensemble. Gordon Cormier plays Aang, Kiawentiio plays Katara, Ian Ousley plays Sokka and Dallas Liu plays Zuko in the live-action series. Season 2 also introduced Miya Cech as Toph.
This distinction matters when searching for an Avatar cast guide because the phrase can refer either to the original animated voice actors or Netflix’s live-action performers.
Who Plays the Main Characters in Netflix’s Avatar?
Netflix’s live-action adaptation began in 2024 and has now moved beyond its first season.
The live-action version retains the basic characters and world created by the animated series but uses new actors to portray them in a physical, live-action setting.
Gordon Cormier leads the cast as Aang, with Kiawentiio as Katara, Ian Ousley as Sokka and Dallas Liu as Zuko. Miya Cech joined the main group as Toph in Season 2.
Season 2 was released on Netflix on June 25, 2026, and the third and final season has already completed production. Netflix currently lists Season 3 for 2027.
That means fans looking up the Avatar Netflix cast are now following a continuing live-action adaptation rather than a project that is merely being developed.
Is the Original Avatar Voice Cast in the Netflix Series?
Some original animated voice performers have appeared in the Netflix adaptation, but viewers should not expect the original voice cast to simply reprise their animated roles in live action.
The two productions have separate principal casts, with the Netflix version reimagining the characters for live action.
For anyone primarily interested in the original Avatar: The Last Airbender voice cast, Zach Tyler Eisen, Mae Whitman, Jack De Sena, Michaela Jill Murphy, Dante Basco, Mako, Greg Baldwin, Mark Hamill and Grey DeLisle remain the key names to know.
Why the Avatar Voice Cast Still Matters
The success of the original animated series was not built solely around its world, bending system or fantasy storyline. Its characters worked because the performances gave each member of the cast a distinct personality.
Aang’s optimism, Katara’s determination, Sokka’s humor, Toph’s confidence, Zuko’s internal conflict and Iroh’s wisdom all depend heavily on the actors behind them.
That is why searches for the Avatar voice cast continue years after the original series ended. The actors did more than provide dialogue — they helped establish the personalities that made Team Avatar and its wider world memorable.
The Netflix adaptation has introduced those characters to another generation through live action, but the original animated performances remain the foundation for how many fans first experienced Aang, Katara, Sokka, Zuko and the rest of the Avatar universe.
Final Thoughts
The Avatar: The Last Airbender voice cast remains one of the most important parts of the animated series’ enduring appeal. Zach Tyler Eisen, Mae Whitman, Jack De Sena, Michaela Jill Murphy, Dante Basco, Mako, Greg Baldwin, Mark Hamill, Grey DeLisle and Dee Bradley Baker each brought a distinct personality to the world of Avatar.
For longtime fans, these performances remain inseparable from the characters themselves. For newer viewers discovering the franchise through Netflix’s live-action adaptation, the original animated series offers another way to experience the same characters and story.
Whether you’re looking for the Aang voice actor, Zuko voice actor, Katara voice actor, Toph voice actor, or the complete Avatar The Last Airbender cast, the original English voice cast remains an essential part of the franchise’s history.
