>>93851755Most things aren't canon. And none of the killings of earth 2 happended on earth 1. Even if Earth 1 batman did wore earth 2 version first costume.
Even oost crisis threw out stuff or added in.
Nu52 has no humanoid murders.
I also don't count earth 2 bat man as earth 1 batman. But Earth 1 batman was morphed into post crisis Batman.
Earth 2 batman ceased to exist post crisis, from his jsa adventures to the times he killed.
Hypertime exists outside the main universe.
