* An Alien
Jenova came from outer space, so yeah, she's an alien being to Gaia.


* Male
Jenova can change its shape, so it doesn't really have a gender. I just call it a she though.


* Sephiroth
Jenova is not Sephiroth, but is controlled by him.

* A dead Cetra/Anicent
Well, yes, it says this in the game.

So what was the point of this thread?
