Netflix has revealed that all three seasons of ‘Avatar: The Last Airbender’ arrives on their service in May, 15th, at least in the US.
The series aired between 2005 to 2008 with 66 episodes and such a captivating finale that many claim it’s one of the best ever.
Synopsis:
The world is divided into four elemental nations: The Northern and Southern Water Tribes, the Earth Kingdom, the Fire Nation, and the Air Nomads. The Avatar upholds the balance between the nations, but everything changed when the Fire Nation invaded. Only the Avatar, master of all four elements, can stop them. But when the world needs him most, he vanishes. A hundred years later Katara and Sokka discover the new Avatar, an airbender named Aang. Together they must help Aang master the elements and save the world.
