Avatar 'The Night Watcher'

This is a Avatar fanfic, I don't own anything, only my Oc.

Lets say the wild beasts of pandora weren't the only things the Na'vi feared. There is a Na'vi that lives alone and has no tribe of there own. This mystery's Na'vi is rarely seen but the ones that have spotted them in the dead of night, say that they've never seen anything like them.
There skin is as dark as the night, there stripes a beautiful white and there eyes were as black as there body was. There were also seen working along side some of the most vicious predators know to the Na'vi. But the reason that the Na'vi feared them is that they have also been known to kill the Na'vi.
This black Na'vi protects the beasts that roam in the night, this is why they called them 'The Night Watcher.'

That's all I can give, I'm going to try and writ this book close to the movie but we'll see where it goes.
I hope ya enjoy it.
