Alex was the adopted son of Jake and Neytiri, two prominent members of the Na'vi clan on the planet of Pandora. He had grown up in the jungles of Pandora, and although he was an outsider, he was loved and accepted by the Na'vi.
What Alex didn't know was that he had been chosen by an ancient spirit to become the bearer of an incredible power. He was the chosen one, and he was destined to protect Pandora from an ancient evil.
One day, when Alex was out exploring the jungle, he stumbled upon a strange blue box. Inside the box was a strange man, called the Doctor. The Doctor told Alex that he was a time-traveller, and that he was on a mission to defeat an ancient evil.
The Doctor asked Alex to join him on his mission, and Alex was more than willing. He was excited to explore the universe, and to use his newfound power to protect the planet of Pandora.
The Doctor and Alex set off on their journey, and soon they picked up some new companions. Lo'ak, Neteyam, Kiri Tuk were all Na'vi, just like Alex, and they joined the Doctor and Alex on their quest.
Along the way, Alex learned more about his newfound power, and he was able to use it to help the Doctor in his mission. Together, they were able to thwart the ancient evil, and save Pandora.
At the end of the journey, Alex returned to the Na'vi village. He was welcomed home with open arms, and he was happy to be reunited with his mom and dad, as well as his brothers and sisters.
Alex had come a long way since the day he stumbled upon the blue box. He had gone from an outsider to a hero, and he was now the proud bearer of an incredible power. He was the chosen one, and he would use his power to protect Pandora forever.
