Production
The season was produced by Nickelodeon Animation Studio and aired on Nickelodeon, both of which are owned by Viacom (now Paramount Global). The season's executive producers and co-creators were Michael Dante DiMartino and Bryan Konietzko, who worked alongside head writer and co-producer Aaron Ehasz. Most of the individual episodes were directed by Ethan Spaulding, Lauren MacMullan and Giancarlo Volpe. Episodes were written by a team of writers, which consisted of Aaron Ehasz, Elizabeth Welch, Tim Hedrick, and John O'Bryan, along with creators DiMartino and Konietzko.

The season's music was composed by "The Track Team", which consists of Jeremy Zuckerman and Benjamin Wynn, who were known to the show's creators because Zuckerman was Konietzko's roommate.

Cast
All of the central characters generally remained the same: Zach Tyler Eisen voices Aang, Mae Whitman voices Katara, Jack DeSena voices Sokka, Michaela Jill Murphy voices Toph, Dante Basco voices Zuko, Dee Bradley Baker voices Appa and Momo, and Grey DeLisle voices Azula.

Additionally, Mark Hamill reprises his role as Fire Lord Ozai in a greater capacity after having minor appearances throughout the first and second seasons of the series, while Greg Baldwin now voices Iroh due to Mako Iwamatsu's death.

Reception
The season received critical acclaim, winning a 2008 Peabody Award. Jamie S. Rich from DVD Talk remarked, "In addition to the solid writing, Avatar the Last Airbender [sic] also has amazing animation. The character designs, with its roots in classic Asian folklore, are colorful and inventive, and the overall animation is smooth and consistently executed". Jamie S. Rich wrote in another review:

This final season in the trilogy is turning out to be the best... At this point in the story, major things are happening, with the characters going through changes and the various plot elements coming together. Thankfully, the show creators never rest, and the quality control is top-notch. The writing is smart, and the animation always impressive. (2008)

Henrik Batallones, a BuddyTV Staff Columnist, also noted the wide variety of positive reviews from the press for the series finale, noting that sources such as The New York Times and Toon Zone gave Avatar: The Last Airbender "glowing reviews".

The season also received praise for its video, redemption of Zuko, and sound quality.
