The Legend of Korra is the sequel to the iconic classic Avatar: The Last Airbender, and just like its predecessor, the series is filled with many amazing characters. Though Korra often pales in comparison to the original series, its cast is one of its strongest features. The series introduces many different characters, all with their own unique backstories that tie into The Last Airbender somehow.
