How do you mean? Do you mean like what Wookieepedia does with Canon/Legends content? I've just been using the {{Distinguish}} template to create a small blurb at the top, that way it's easy to switch between articles. I'd definitely be open to suggestions though. I tried using the Wookieepedia tab system at one point but it's not very mobile-friendly (and half of wikia users view our content on mobile).
I actually got this idea from looking at The Walking Dead Wiki (http://walkingdead.wikia.com/wiki/The_Walking_Dead_Wiki) which is another wiki for a show based off a comic book. If you go to that site you see that at the top there are three different tabs. One says "Comic Series", one says "TV Series", and the last one says "Video Games". Now Powers has no video games of course, but we could still create the two tabs. One would be for the TV Series and the other for the comic.
