And as I was driving into work at the ungodly hour of 5 AM in the morning, I get ambushed by a particularly weird and twisted plotbunny. And horribly evil, of course.
How about Sephiroth as an immortal god-emperor, and Zack as the constantly reincarnated/cloned uber-loyal friend/retainer?
And if this setup sound vaguely familiar, I confess that the setup was shamelessly stolen from the Dune series by Frank Herbert, with poor Zack getting stuck in the Duncan Idaho-type role.

Okay, now I've written you down, go away, damn it! I do NOT need another faction of rabid FF7-plotbeasties taking up residence in my heads!
