You and I can put our heads together for that because I'm not talking about the standard well used villains.  The truly great ones don't even have a costume.  For them it's just a matter of finding a beard or sculpting a bald head.  I'm speaking of new villians that haven't been thought of yet.  I'll put my soapbox away and I'll email you some thoughts.  After all, you like the heroes of today but aren't you more interested in Green Lightning?  I am!
