If this is true, then Enuo is Ex-Death. The background is the same of the Neo Ex-Death, so, in my opinion, Enuo is probably a third(final) form of the final boss.
I completely forgot about that! It's been a while since I've completed FF V.

And maybe adding Enuo will make the story more solid. He really should have been in the original as a mandatory fight.
