The Legend of Korra (2012 — 2014)

The Legend of Korra (2012–2014) is an American animated fantasy action TV series created by Michael Dante DiMartino and Bryan Konietzko for Nickelodeon. In the initial season, Book One: Air, Korra relocates to Republic City to train under Tenzin, the son of Avatar Aang. She becomes a member of a pro-bending team with brothers Bolin and Mako, while also forming a friendship with Asami Sato, heiress of a prominent engineering corporation. The determined politician Tarrlok enlists Korra’s help in quelling the ‘Equalists’, a group led by the masked Amon who strips benders of their abilities. Alongside police chief Lin Beifong, they uncover Amon to be a waterbender and Tarrlok’s own brother, ultimately thwarting the Equalists’ takeover. In the follow-up season, Book Two: Spirits, Korra’s uncle Unalaq takes control of the Southern Water Tribe. As her friends seek support against Unalaq’s reign, Korra discovers new information about Wan, the first Avatar who fused his soul with Raava – the spirit of light – to trap Vaatu, the spirit of darkness. During the Harmonic Convergence – an alignment that occurs every 10,000 years – Unalaq releases Vaatu and merges with him to become a dark Avatar.

The third season, Book Three: Change, sees nonbenders gaining airbending powers due to Harmonic Convergence. Tenzin, Korra, and their allies work together to persuade these new airbenders to join the re-established Air Nomads. Among them is Zaheer, leader of the anarchist Red Lotus group. This dangerous organization plots the assassination of the Earth Queen, causing chaos in her kingdom. They also capture Korra with the intention of ending the Avatar cycle. However, with the help of Korra’s friends and the newfound airbenders, they are defeated. Though victorious, Korra suffers severe physical and psychological trauma. Book Four: Balance takes place three years later as Korra slowly recovers from her injuries and mental scars. Kuvira, a metalbender tasked with reuniting the fractured Earth Kingdom, declares herself ruler of the new ‘Earth Empire’. She builds a spirit-powered weapon to conquer Republic City but is ultimately thwarted by Korra and her companions. The explosion caused by destroying this weapon opens up another portal to the Spirit World.
