That's a good question, and a question that many wikis never consider.

In general, the question becomes: "How do you handle a subject which exists in the universe, but is not covered within the scope of the wiki".

Air? Earth? USA? The White House? The Presidency of the USA?

A lot of media features those subjects, at least in passing, so does a wiki need a page on those things? Some say yes, and proceed to duplicate those wikipedia articles verbatim.

I say no. I say "Define the scope and stick to it". I say "Link to wikipedia for articles outside the scope". So, yes to an article on "President Made-Up-For-This-Franchise", but no to a article about the position itself: link to wikipedia for that. (This isn't a made-up example, someone copied that page once.)

Applying "Define the scope and stick to it" to the specific case, it would likely mean linking to many articles on the DC wiki, in which case there are no links back, and thus it makes more sense to be part of that wiki to begin with.
