The Water Tribes consisted of mainly Caucasians and people of Inuit descent, due to the casting of Nicola Peltz and Jackson Rathbone. The Earth Kingdom consisted of East Asian and African American actors. The Fire Nation consisted mainly of Indians and people of Caribbean background. The Air Nomads, however, are mixed cultures and do not consist of mainly one or two nationalities. There are few exceptions, but they still generally fit the overall visual look of the nations.
