Here's a breakdown of how the movie ends:
Spoiler Alert!
* Jake Sully's Choice: After being paralyzed and sent to Pandora, Jake chooses to permanently transfer his consciousness into his Avatar body. This means he will never return to his human form.
* The Battle for Pandora: The humans, led by Colonel Miles Quaritch, attack the Na'vi and their home, Hometree. Jake, alongside Neytiri and the other Na'vi, fights back fiercely.
* The Turning Point: In the final battle, Jake, riding Toruk, the great leonopteryx, rallies the Na'vi and defeats Quaritch.
* A New Leader: With the human threat neutralized, Jake becomes the new leader of the Na'vi, taking on the role of the "Toruk Makto."
* A Promise for the Future: Jake and Neytiri have a son, making him a symbol of hope and unity for the Na'vi. The film ends with the promise of a new era for the Na'vi under Jake's leadership.
The ending of "Avatar" is bittersweet. It marks the end of a war and a new beginning for Jake, but it also leaves us with the knowledge that he will never see his human family again.
