About the Final Bosses thing, in spite that I would have loved to see Zeromus, Necron, and others like them as playable characters, I'm happy they didn't put them... 'Cause that way, characters like them can keep their GREAT power, and with that, their reputation. :B
I mean, if Zeromus was killed by 5 character in FFIV and he could have been difficult that way, would be kinda odd to watch him/it get killed by just one character, and maybe with just 1 low level character in Dissidia...
Isn't it weird that Sephiroth, for example, with all his overpowerful reputation, can get killed so easily in Dissidia??? (I'm talking about story mode or common battles, not about the Inward Chaos or Blackjack ones)... If he can be so easily killed in Dissidia (being the same person), why the hell he, as an ex 1st Class Soldier, was so feared in FF7???...

I get annoyed a little bit because of things like that in Dissidia, I mean, we need a little more of concordance in the games =/ ... A guy who can kick your ass even if the battle is unbalanced (4 or 5 against just one), and who had a whole game to get beaten, should not be so easily beaten in a one-against-one battle, and even worse, if you're beating him with one of those guys who got his ass kicked when being not alone in the earlier game... =/

I think Chaos forces are being looked down in Dissidia cause they were powerful guys in the earlier games... But of course, those are the rules in a Fighting game... So is understood... But I want to think that maybe that one is a reason for having not chosen some bosses... choosing other villains in their place...

Another reason could have been the technical difficulties to model them in 3D for a fighting game... being, like Zeromus, some of them, more a mass-like thing instead of an individual... I don't know if I can explain it well... D:

Of course, the other big reason is the way they can fit Dissidia story and the main villain role they had in their games... Like in Golbez case.

Specifically about CoD, Xande would have been great, but I think she got chosen instead of Xande just because of the lack of females in the playable characters list, cause they are mostly males. (4 females and 18 males, if I'm not forgetting or changing the sex of someone xD...)

Talking again about the question of this thread... I insist that Aki Ross would have been an awesome hidden playable character in Dissidia ?
What do you think?
