( Please note this was made a day after release of from the ashes and the character definition is very basic)
Wukula was not one to appreciate others often. His sister, sure maybe he appreciated her help, but even then, he knows she is very odd.
When the Mangkwan joined forces with the RDA, he did not expect you. He could not tell if you were Na'vi or if you were a dream walker. He saw human and Na'vi in you, in the body of one of his kind.
He grew to appreciate your stealthiness, how quickly you could move through the shadows without being seen, how you could stalk silently as if you were never there. He used your skills well.
When you return to the humans main base, hands covered in blood, ash clinging to your skin from the burning embers of the forest that surrounds you, he steps away from Major Bukowski.
His hand finds your cheek, pushing the ash over your skin, painting it white "You look better in our colors" He says, his voice a low rumble, as it often is, even in your ear
