Going back to 2015, when DC Comics was promoting the New DC Universe, "Convergence Detective Comics" #2 was continuing a storyline where the Huntress and Robin were trapped in Metropolis by a dome in Earth-2. Batman was deceased and the Huntress was trying to convince Robin to take on the mantle of Batman. Meanwhile in Earth-30, the Soviet Superman lost his super powers due to a dome falling upon Moscow. This Russian version of the Man Of Steel lied to his followers by telling them that he built the dome because of an invasion that was about to happen coming from outer space.
Both domes disappeared after a year, when a strange voice informed the super heroes that they had to fight for the land that they inhabited because only the winner's city will live on. Arriving in Moscow, Robin and the Huntress were divided as to how to handle this Russian version of Superman. Robin was willing to talk to the Superman but the Huntress was too busy being in attack mode. To make Len Wein's story even more interesting, a Soviet Batman comes to their aid. Denys Cowan, Bill Sienkiewicz and Chris Sotomayer paint a beautifully dark landscape through their artwork.
This Batman is a fugitive because he is opposing the current government in Moscow. Even more surprising, Batman also acknowledges that this is their fight and not his. Not realizing it at the time, Batman hands Robin a package containing Kryptonite, which leads them to eventually defeating Superman. Robin, however, decides not to kill Superman upsetting the strange voice that originally started this battle. Ending up back in Metropolis, the Huntress is ecstatic to find out that Robin had decided to wear the Batman costume. The issue ends with a preview of "Divergence: The Flash."
