DC rebooted its universe. Superman and Lois were married prior to the reboot, but post-reboot the characters are younger and they haven't dated yet. So, Superman's apparently trying to get with Wonder Woman.
Gorgeous as always. Lois kicks the bucket basically. She either ages or dies. She is a human and not compatible physically with Superman so they can't really have kids and he is an alien with longevity. Wondy is basically a demi goddess and long lived too. It's not only Kingdom Come...they marry and have children but many alternate timelines as well. The Dark Knight Returns universe they have a daughter. Here is a helpful link [link] for some of those alternate stories. And this tumblr has stuff from the silver age with them too. [link]
Plus there are officially 52 earths now with all different histories. In Red Son for example Superman and Lois are not together.
Will you one of Selina/Batman and Superman/Wonder Woman like that awesome one of him and Talia?
