Could Necron be next tier boss? My thoughts and yours?

[Kyuuen]

Kuja was not the one that wanted to return everything to return to nothing-ness. He wanted everyone to die with him cuz he believed that he was the perfect being. Since he life span was short, he believe the world should not exist without him.after winning the fight, Kuja used Ultima. Necron (the god of death) appeared and said he was going to return all to nothing-ness, where there is no fear of death. And since death is a big theme of this game, it makes sense, considering Terra was slowly dying, vivi's short life span, ect. FF7's background story with life stream seems quite similar with 9. The lifa tree was taking in all the souls and creating that mist. And I always thought the dude you fight inside the lifa tree have some plot tied with Necron.

Thanks for the correction, it's been a while since I've completed a play through. But my point remains, that Necrons showing up isn't hard to explain.

I don't remember Omega traveling to IX Realm? Did he? Been a while since I play IX I may buy for PS4 since it got released I think.
I know the Omega originally release in V so is well explain Exdeath since he did travel to V realm same for Chocobo Tales , he BEEN in the Chocobo tail Realm.
I remember Omega being in X, so we may fight
O5 Jecht
O6 Seymour
O7 Yunalesca
O8 Sin

Is that what's going on in the Deltascape? Omega is only pulling beings from worlds/realities/dimensions from which it's been?
