Avatar: The Last Airbender made its live-action series debut earlier this year, and now one awesome cosplay has gone viral for bringing Appa to life in a cool new way! Avatar: The Last Airbender premiered its newest live-action series with Netflix earlier this year, and took over the streaming service for a few weeks. The series ended up having such a successful launch that Netflix quickly confirmed that Avatar: The Last Airbender would be returning not just for a second season, but a third season to help wrap it all up as well. But it's going to be a bit of a wait before we get to see what's next.
