JB: As I have often noted, the one thing that most clearly defines DC is the "de-uniquing" of their characters.
I don't mean creating franchises. Superman and Batman, for instance, have always had multiple titles, at least from the point at which they got their own books. What I am referring to is the multiple iterations of characters with the same powers and abilities -- So for Superman we see Superboy, Supergirl, Krypto, Comet, Streaky, and all the inhabitants of Kandor. Batman gives us Batwoman, two Batgirls, Bat-Mite, Ace the Bat-Hound and several future Batman. Many of the characters had kid versions, as with Kid Flash, Aqualad, Wonder Girl, etc. And, of course, Green Lantern was the least unique character ever, with literally thousands of beings who could do exactly what he did.
Even when we were presented with a character who was effectively a "one of", like J'Onn J'Onzz, we had to have a whole race of beings to whom his abilities were just standard issue, like having brown eyes. As a kid, I enjoyed all the multiples of multiples, but as I got older, and especially after I got into the business, I got to really wishing there was some way every DC character could (much like their Marvel equivalents) be the only ones. Not surprising, is it, that once a generation of writers and artists raised on Silver Age DC started working at Marvel, we started seeing multiples of the characters -- multiple Captain Americas, for instance, or "parallel universe" versions of the FF.
