New Avatar Series!

"Mike and Bryan have imagined a compelling new story inspired by the Airbender mythology that they so brilliantly crafted when the TV series began," Johnson said. "This new avatar is not only a girl, but also hot-headed, independent and ready to take on the world."
The Legend of Korra takes place 70 years after the events of Avatar: The Last Airbender and follows the adventures of the Avatar after Aang – a passionate, rebellious, and fearless teenaged girl from the Southern Water Tribe named Korra. With three of the four elements under her belt (Earth, Water, and Fire), Korra seeks to master the final element, Air. Her quest leads her to the epicenter of the modern "Avatar" world, Republic City – a metropolis that is fueled by steampunk technology. It is a virtual melting pot where benders and non-benders from all nations live and thrive. However, Korra discovers that Republic City is plagued by crime as well as a growing anti-bending revolution that threatens to rip it apart. Under the tutelage of Aang's son, Tenzin, Korra begins her airbending training while dealing with the dangers at large.
Launched in February 2005, Avatar aired for three seasons on Nickelodeon and was ranked among the top five animated properties on television among boys, 2-11 and 6-11 (2005/2006).

Currently, Avatar: The Last Airbender is the number one program on Nicktoons among tweens. (Source: *Nielsen Cume Data - July 2008, Live + 7 day, 6 min. qualifier.)
