Woah jeez. Lots of people raging at the new voice. xD
Just putting in, if this female voice actor was supposed to be playing the role of a male, then we should not be able to tell that its so obviously a female doing the part and she isn't doing a very good job at sounding like a guy. I saw several posts saying that maybe shes just voicing a guy and it didnt make much sense to me.
Anyway, im not upset about any of the news really. Im cool with there being a different Mewtwo and im cool with it having a female voice/being female. Nothing wrong with that, in my opinion. If they come up with a decent backstory as to why there are multiple Mewtwos (which really shouldnt be too hard to explain) then thats awesome. Also, I think having a strong female role is a great idea on Pokemons part, who said females cant be BA? I'll only be upset if they give it that drastic of a voice/gender change and claim it to be the same one as before. As of now, although I would have preferred it to be the same original Mewtwo just for nostalgic purposes, I hope it is a different Mewtwo for the reason of it having a major voice change. Im not so attached to the nostalgia that I would hate any sort of change, though.
And then we all still have to consider, this is only the Japanese version. Theres still a chance they'll keep the Mewtwo Strikes Back VA for the dub, although it would be inconsistent to change the Japanese and not the American. Then again, its also inconsistent to change the VA of Mewtwo at all, unless it is an entirely different one which I hope. Even so, some people are saying the new female voice isnt "powerful" enough. Again, its only the Japanese version. We have no idea what the dub might sound like. Even if they do change the voice to a female in the dub too, it will be an entirely different voice and chance of it having that "power" in the voice. (although I dont really see anything wrong with the current JP voice)
And also, for some people that still think its not a form.. the video directly shows Mewtwo transforming into it.. it cant be much more obvious than that.
About the whole legendary gender thing, sure, we all know that most legendaries are genderless
in the games. It is often clear in the manga and anime, though... but the games, anime, and manga are all separate sections controlled by different people.
As WPM said, they do it primarily as a breeding block for the games. However, if that was the sole purpose, I dont know why they dont just give it some sort of invisible coding for that, or I guess for example just keep them in the unbreedable egg group (baby Pokemon have genders yet they cant breed...)
I'd like to add that I think it gives most legendaries a sense of mysteriousness, since they are so rare, there isnt so much information on them and the gender is just kind of unknown in a sense. But it is true that some legendaries do have genders, which in all honesty, I really cant explain why some do and some don't.
