I'm sorry, Clock, but it would be nigh impossible for us to make -some- of the family members into villains now. We've sorted out a very specific background for them, and the way they were brought up would make it very, very difficult to have some of the siblings go to the dark side due to the lack of outside communication, and the two parents were both very noble and heroic people.

I was planning to make them into villains first, but at the time there were more villains than heroes. I'm certain more people can join and even things out, though! \o/
