Another alternate worlds/hero mix up issue.
The issue starts off with Supes and Bats suddenly finding themselves in an alternate world called Gothapolis - in which many heroes are a combination of two heroes from Supes and Bats world and upon seeing Superman and Batman - would rather beat them shitless than try to talk to them and figure this out reasonably.
I'm getting just a little bit tired of these types of stories.
