James Cameron faces accusations of copying Avatar: The Last Airbender plot for Avatar 3.
Netizens compare Avatar 3's "Ash People" to The Last Airbender's elemental nations.
The Last Airbender aired from 2005-2008 on Nickelodeon and follows a 12-year-old boy's journey.
Cameron's Avatar 2 has a coastal community and many underwater scenes.
The Last Airbender deals with Earth, Water, Fire, and Air elements.
