Not yet, but in the future they might be!
its obviously aang the opening says hes the avatar.
Avatar is a film. Mostly created with computer graphics. It is fantasy.
Aang
are time machines real
yes
The book is real. The story is fiction.
sadly no
no, i don't think so because avatar is a fictional movie.
It's real in our minds. There is an astronomically small possibility of a planet existing that is close to Pandora but not quite. Other than that, it's all fiction.
It can.
yes they are, i have one
there is no such thing as a real avatar but if you mean how long tv has had them will ask the tv because i dont know.
