Book One: Air is the first season of the American animated television series The Legend of Korra created by Michael Dante DiMartino and Bryan Konietzko.

Tarrlok, an ambitious member of the city's ruling council, enlists Korra against the "Equalists", an anti-bender revolution led by the masked Amon.

As Korra explores Republic City, she befriends the brothers Mako and Bolin and joins their pro-bending team, the "Fire Ferrets".

In the two-part finale, naval reinforcements led by Iroh (the grandson of Zuko of the original series), are defeated by Equalist sea mines and biplanes.

The website's critical consensus reads, "The Legend of Korra expands the world of Avatar: The Last Airbender with narrative substance and crisp animation -- and progresses the drama and action with a female lead.

"[17] Elements of the first season that received praise were the exceptional quality of the animation, the background paintings[18] and the martial-arts action scenes,[19] as well as the series' innovative and engrossing visual design and style.

[19][21] Critics also praised the writers' willingness and ability to tackle difficult themes such as social unrest,[22] terrorism, Tarrlok's murder–suicide of Amon,[23] as well as the insinuation of Korra contemplating suicide during the season finale.

[27] Raz Greenberg of Strange Horizons commented that Korra seemed as though she had things too easy in life in comparison to Aang, and also criticized the show's rapid pacing.

[28] Max Nicholson of IGN praised the series' writing, animation, humor, setting, and characters, and wrote that elements characterized as a deus ex machina had been foreshadowed throughout.

The Blu-ray version comprises, additionally, audio commentaries for all episodes as well as the extra "Series creators' Favorite Scenes: Eight Animatics".

The novelizations were published by Random House in 2013:[32] The Legend of Korra is set to music by "The Track Team", the partnership of composers Jeremy Zuckerman and Benjamin Wynn.
