Dark Metamorphosis
That would make sense.
Did you heard about how some fans aren't liking her? USA might get new characters while she stays in the Eastern.
Yes, it wouldn't be the first time that a fighting game has characters that are obviously influenced by previous fighting games as all 3D fighting games came after Street Fighter so someone like Akira Yuki looks a lot like Ryu.
Yes, I've read plenty of complaints. I doubt it as NO characters have ever been dropped based on complaints alone during the 20-year history of the franchise. Characters have been added to console ports plenty of times though.
