superheroines, you need a villain?

This is a out to become a thread geared toward antagonists for superheroines. I plan to detail it out though, adding a variety of characters. I'll do Canon or OC villains, everything from super powers down to street thugs.

I'm good with Canon or OC heroines but I prefer them to have a back bone and not be trying to lose.

Don't get me wrong though, they will likely lose.

Superheroines, PM me with any villains you would like to see and I'll see what I can do.
