It only makes sense that Avatar: The Last Airbender, an impressive animate television series ( we think, the best , the most impressive), should also have an impressive list of voice acting talents.

And Avatar doesnt just boast beloved voice acting pipes like Mark Hamill (Fire Lord Ozai) and Scott Menville (an actor playing Sokka); it also sneaks in several guest cameos, like Jason Isaacs, who plays Lucius Malfoy in the Harry Potter movies (and Avatar's equally evil General Zhao), Serena Williams (who voices a prison guard), and freaking George Takei (who voices a prison warden). Evidently, there are a lot of prison characters in Avatar.

But the series principle cast of voice actors really brings it all home, voicing Aang, Sokka, Katara, Toph, and Zuko. And, of course Appa and Momo, voiced by Dee Bradley Baker, who said he made up most of the sounds just based on the sketches he received of the two creatures (which are closest to a lemur and a bison).

Here are all the actors who voiced the major characters.

Zach Tyler (Aang)

Tyler was eleven when doing the voice acting for Aang (12 in the show) in season 1. Tyler also did voice acting work for The Backyardigans and The Ant Bully, but more or less disappeared after the series. Typical Avatar move.

Jack De Sena (Sokka)

De Sena described Sokka as a goofball and said he mostly had to just exaggerate all of his instinctual voices. (Which must mean De Sena is also kind of a goofball; people of a certain age will remember him as such on Nickelodeon's .) Hes now the voice of Callum in Netflixs The Dragon Prince.

Mae Whitman (Katara)

Whitman is also a recording artist and screen actor (best known for her roles in Arrested Development and Good Girls), appearing in Independence Day when she was eight.

Dante Basco (Zuko)

Basco was one of the older voice talents for the series kids. He was 28 during the shows first season. Basco also voices Jake Long in American Dragon: Jake Long and Iroh II in The Legend of Korra.

Jessie Flower (Toph)

Flower was the same age as Toph (12) during some of the voice acting.

Mako Iwamatsu (Uncle Iroh)

Maybe the most accomplished actor in the cast, Mako was nominated for both an Academy Award and a Tony. He passed away after the second season of the series. Greg Baldwin then became the voice of Iroh as well as another famous Mako role: Aku in Samurai Jack.

Grey Griffin/DeLisle (Azula)

DeLisle has voiced everything. She was Sam in Danny Phantom, Mandy from The Grim Adventures of Bill & Mandy, and Daphne from Scooby-Doo. She now voices the characters of Martin, Sherri and Terri on The Simpsons.
