I'm not sure Steve has been in a Wonder Woman run for quite a while now. Him being a relevant character in the DCU is on thing. DC has really tried to make him relevant in their new universe, except that he's not very relevant to Wondert Woman now. He's becoming a Nick Fury kinda guy, he's only tangentially linked to Wonder Woman at the moment.
I did mention Cheetah being a rare exception.Cheetah has been in Wonder Woman...
I don't remember her in Wonder Woman. I remember her in Secret Six, I remember her as the Atom's love interest. I have never seen her used as a Wonder Woman rogue except in the terrible Allan Heinberg pseudo-reboot.Giganta in Wonder Woman, Secret Six, Forever Evil, and Pandora.
At this point I don't think Donna Troy is still a character. She's had a few reimaginations too much. It would seem Sandsmark has eclipsed her place in the DCU.Donna Troy was in Wonder Woman, Titans, and Justice League of America.
