Not really; the Zurr-En-Arrh element was originally an alien fanboying over Batman. Seriously, he picked up transmissions somehow from Earth and was modeling his own "crime fighting" on Batman, only using Zurr-En-Arrh technology . . . and a brightly colored costume. It doesn't add anything to the modern story, really, knowing what it's actually about. But, interestingly, it doesn't subtract anything, either. I felt that thehefner's complaint about Morrison's use of long-forgotten Silver Age (and Golden Age) material is unfair, because generally, Morrison changed the older stuff significantly, summarizing (or attempting to summarize) for the audience what was needed, whereas Dini is actually using stuff from ages past, modernizing without really deconstructing.
