Can someone explain to me how we know Donna will be a "robot doing her creator's bidding?" I've seen nothing to back that up.
So Donna was born with a somewhat vacant look in her eyes. That can just as easily mean she hadn't achieved full consciousness yet.
It seems much more that Donna will follow her creator's directives, because they'll be able to manipulate her young mind into believing that their way is best. This will put Donna firmly in the "misguided" class of villains. Misguided villains, by the by, are Diana's favorite villains to reform.
