No. We do not speak of that horror of a character... 12... so dumb. Nekro on the other hand.... hmmmmmmm that would be interesting to see him come back in some way, even as a background character.
Out of my way!
Back to the satsui no hado thing, here is my line of thought.
Imagine that there is some sort of god, creature, or demon, some war entity. And that creature is the source of the "satsui no hado" powers. (we already have ingrid as the original source of the psycho power, right?) Now, imagine that in acient times, that creature was worshipped not by one, but a lot of tribes and different cultures in general, is not hard to assume that the ansatsuken, that in its original form taps the satsui no hado started as some sort of cult in the ancient Japan, and that by coincidence (or any other reason really), that creature is worshipped by Necalli's people/tribe or whatever. And what makes me think of that, the way he holds ken's head in the trailer, is like he is doing some sort of offering, or sacrifice, to some sort of deity. But hey, is just a theory...
I still believe that this game is post SF3, When i meant by chun getting back by personal means, i mean, she took the first step towards getting back into action, something like "i need to work again", instead someone reaching her and giving her a mission.
Now, if alex is in the game, it is post SF3 for sure, since in new generation we have the beginning of alex adventures. =P
