|Behind the Scenes|
Nikiro is a Na'vi warrior in Tantalus region on Pandora. He is located in the Na'vi village on the way from Nesting Grounds to The Great Wall. He uses Pandora's Protection skill. Nikiro is only visible when Able Ryder joins the Na'vi side.
Since the area is inaccessible to the player through normal means, it can be guessed that the character has been removed from the story. Further proof of that theory is the "FIX ME!" tag on his name.
