Now imagine for one second that the roles are reversed and it is Spider-woman and Captain Marvel who are made to strip and dance for Wolverine and Tony Stark's amusement while being lectured about gender roles in today's society.
When did DC get the right to Tom Strong? Jim Lee doesn't own his rights. TS was created by Alan Moore from everything I heard he hates DC for screwing him over and taking the rights of his Watchmen away from him, no way would he ever let DC have his character in their Universe.
In a nutshell: America's Best Comics is a WildStorm imprint; and Wildstorm is a DC imprint. So like Mungi said: DC has technically *always* had the rights to Tom Strong -- they just haven't used him in a mainstream title until now.
That said, I'm hoping Tom Strong is just the start... There were LOADS of great characters from the ABC-verse.
...and I think it mimics an even older cover from the Stan Lee days. But both were parodies. The joke was that Pete was always the exact opposite. Even the "Action is his reward" line on that cover is just a nod to the old theme song, and his line on the cover echoes MJ's classic line; it's not something he'd ever say.
We probably can't discount random male-centric storylines from the 60s and 70s. I'm sure he calls some staff reporter at the Bugle "doll" or something. But I'm reasonably sure Pete's been assumed to be gay more often than he's done anything overtly chauvinist. And the time period(s) between "hopeless nerd," "crying over Gwen," and "in a long-term relationship and/or married to Mary Jane" wasn't too long, tbh. Any real womanizing that I'm forgetting would have to have been in a really tight window of time.
