Alexander

[Dualblade]

I get what you're saying though, the reoccurring elements are reinterpreted every game to some extent or another. But Being of a holy element and being mechanical I think are Alexander's two defining features. To change one would be like making chocobos large, yellow, rideable lizards and not birds. It could probably be done, but it would be a hard sell.

Another thing to not too is that just because something is the Holy element doesn't mean it has to be on our side, just like being Darkness doesn't mean it has to be opposed to us. Its actually kinda funny to think of now, we get Dark Knight as a playable job at the same time the Holy Primal appears.
