:::I could, but then...it sounds rather childish to me, don't you think? There are plenty of other wiki character pages, where the term "archenemy" and "nemesis" or whatever is tossed around (see for instance, the Atom villain Chronos) and there are no sources whatsoever to back them up. Why don't you go and remove them, since you're passionate about making sure information of dubious quality and reliability get off wikipedia pages?  

 FYI, I added the IGN entry about Dark Phoenix being ranked as a top 10 comic book villain on the Jean Grey page complete with the citation months ago, and so far no one has bothered to remove or reverse it. Mind you, Jean or at least one of her personas being branded a "villain" is an unpopular sentiment. Maybe because people like the fact that I actually cite what I write?
