"Avatar: The Last Airbender" is primarily an animated television series, not a movie. However, Netflix is developing a live-action adaptation of the series. In the original story, Aang is the current Avatar, representing the Air Nomads. The Avatar is reincarnated into a new nation with each cycle, so a new Avatar will appear in future stories, but it will be a different character from Aang. The upcoming adaptation may explore Aang's journey, but it will not introduce a new Avatar in the immediate narrative.

As of now, there is no official announcement regarding a sequel to "The Last Airbender," the 2010 film directed by M. Night Shyamalan. The movie, based on the animated series "Avatar: The Last Airbender," received negative reviews and did not perform well at the box office, which has likely impacted the chances of a sequel. However, Netflix is developing a live-action adaptation of the original animated series, which may be of interest to fans. Keep an eye on official announcements for any updates.

In "Avatar: The Last Airbender," the series itself does not explicitly label any characters as LGBT. However, there are strong implications regarding the sexuality of some characters. Notably, the creators have confirmed that the character of Korra from the sequel series "The Legend of Korra" is bisexual, as she has romantic relationships with both Mako (a male character) and Asami (a female character). Additionally, the relationship between Asami and Korra is depicted as deep and romantic, particularly in the series finale.
