search this picture carefully. notice how there is no sheik, but zero suit is listed? if this is the actually book, then is it possible that zero suit still has a chance to break off into her own character?

I always thought that would be the way it was regardless, as ZSS's FS is transformation into Samus (Crystal Flash).

Whereas you can switch between Zelda & Shiek at will.

well, yeah, but i mean, this could mean there is a way to unlock her so you can choose her at the start of the match

...Or this could have been done before Shiek was announced.
