In Convergence Detective Comics #1 of two, Len Wein masterfully weaves a tale between multiverses in this issue from 2015. Earth-30 and Earth-2 merge in the panels excellently due to the graphic prowess of Denys Cowan, Bill Sienkiewicz, Chris Sotomayor, Felix Serrano and Travis Lanham. In one world, we see a Superman who is defending the Socialism of Moscow. His powers are gone due to a dome that has come down over the city he swore to protect. Besides dealing with a political rival, the people's trust in Superman is starting to diminish due to shortages with food and merchandise. Surely, Superman can fix this, but his claims to be only one man don't hold water.
In another world, Robin and the Huntress come upon the red skies of Metropolis, which turns out to be another dome over a city. Before Batman's death, he had set up Wayne Foundations in major cities all over the country. Therefore, like Gotham City, Robin had access to the technology he would need in Metropolis as well. Dick Grayson is now an adult, which seems weird for him still to be masquerading as Robin. Helena Wayne, Batman's daughter, is the Huntress.
Superman can't let his Soviet followers know that his powers are gone, so he comes up with ways to fool the public. A voice begins to talk to its prisoners trapped inside each dome. It goes on to say that the defenders of each of these cities will have to battle each other and only one city will survive. After battling the Toyman, Robin and the Huntress watch as the dome lifts from the city. While surveying the situation in the Batmobile, they freakishly travel from Earth-2 to Earth-30. Now face-to-face with a Superman that they don't know, they each have different ideas on how to handle the situation leading to unnecessary conflict.
