That is very much why Last Son of Krypton and I mentioned the Dark Knight universe. They are a thing there, and if the plans to expand the DKR universe, they or the daughter Lara might get spinoffs. It might explain part of why they treat the non-Batman characters better, because they want to expand on it and get people interested in the alternate versions of the mainstream characters, rather than scare off people with the fact that Superman is there in DKR so that Batman can be an ******* and pummel him.
