The series will focus on Korra, a teenage female protagonist from the Southern Water Tribe and the current incarnation of the Avatar, who, according to the president of Nickelodeon, will be "hotheaded, independent, and ready to take on the world."[1] She has already mastered the elements of Water, Earth, and Fire, but needs to master Air.[3] The character was partly inspired 由 阿凡达 Kyoshi of the original series, whom the creators say was very 流行的 among fans. In order to avoid repetition of Aang's adventures, the creators wanted to root the 显示 in one place, called Republic City, a steam-punk style metropolis where people of all nations, benders and non-benders, live together. A concept drawing of the city, released with the announcement of the series, shows the city's 设计 as inspired 由 Shanghai in the 1920s and 1930s, Hong Kong, Manhattan, and Vancouver. In the show, Korra will have to learn Airbending from master Tenzin, son of 阿凡达 Aang and Katara, and contend with an anti-bender revolution taking place in Republic City.
