Jenova might be a WEAPON
I don't know if Max or any other theory crafters have touched on this, but I have a theory that Jenova may be a WEAPON from another planet. I mean Gaia, the planet we adventure on, made the WEAPONs we do know, being Ruby, Emerald, Diamond, Omega, and Ultimate Weapon. So say there was another planet that had one of those self-destructive stories and their WEAPON (Jenova) took their version of the lifestream and looked for another home but something they did corrupted either Jenova or the lifestream they absorbed and rather than being a peaceful alien she was turned into this disfigured, misshaped, and lost being that became possibly resentful or something and now goes planet to planet destroying the worlds and either absorbing their planets life force or just letting it wither away. Also, from what I've read, they (The WEAPONS) were made during the original conflict with Jenova, and since the Ancients were able to communicate directly with the planet, is it possible Gaia basically gave them the blueprint to fend of Jenova as a big red button kind of situation? if anyone has any thoughts or evidence to support/counter I'd love to hear them!
