This is another of those oddities that is dealt with by that hilarious Videogame Recaps site.

The options she gave for the fanwankery poll were:

* Programming and animating an actual believable reaction would have taken valuable time away from animating the 52nd Rinhoa FMV.

* They're all brainwashed. Edea has a wide radius of power, although it doesn't affect five of our main characters.

* People seem to like skullskullskullskullty leaders in general. Look at the US.
I go for the lazy programmers option.
