The Last Airbender and The Legend of Korra explain how one key concept made the official sequel series that much darker.

Though Korra was the Avatar, one capable of bending multiple elements, a highly skilled earth bender should be capable of focusing on the minerals rather than the fluids to blood bend.

But, The Legend of Korra clarifies that the "we" referred to the ancient lion turtles who protected humans and gifted them the ability to bend the elements.

Avatar: The Last Airbender and The Legend of Korra has some kick-ass female benders. Here are some of the best.

Debut Episode: "The Voice in the Night" Hiroshi Sato ranks last among Korra's most dangerous enemies because he is a middle-aged man who can neither bend the elements nor use martial arts.

A new Avatar cartoon, Avatar: Seven Havens, is officially announced and will follow the newest Avatar, an Earthbender.
