No FE u are wrong, Edea's headress does not have any eyes on it and the propagator heads are not transparent. when you fight them on the ragnarok you cannot see through their heads so i dont know where u get the idea that their heads are transparent.
Also this was mentioned before and you never even noticed it but what about all the horns Edea's headress has? The propagators do not have any horns on their heads. Their heads are pretty flat too while Edea's headress is more curved and rounded.
