A friend and I are collaborating on the Marevl/ Dc olympics set of stories. Now this may seem a little early to be starting but the scope of it and other commitments necessiates that we start well in adavnce in order to have the stories done in time. For the partcipants we have had no problem selecting enough male and female heroes from both companies (and are considering making the Xmen their own brand) But where we have run into problems is with female villians for both brands. The only restrictiosn are that they have to be roughly humanoid (so not Lady Styx or Brood Queen, and not be universal power levels)
So far for Dc we have

Harley Quinn
Posion Ivy
Superwoman
Talia
Knockout
Scanal Savage
Blackfire
Cheshire
Fatality
Killer Frost
Star Sapphire
Giganta
Cheetah
Tigress

Now we dont want to go too obscure but really need around 20 -25 to fill out the teams. Any help will be appreciated.

Ravager, Lady Shiva, Silver Swan, Queen Bee and Maxima.
