Given the unique nature of comicbook material, we give them leeway on relying a good deal on primary sources.  It's only when those articles seeks something beyond a C, such as GA or FA status that third-party sources become imperative.  Now give, many of the minor superhero character pages out there are really stubs with little future, it's all about where you stand on the inclusionist/deletionist philosophy on Wikipedia.  Do you give leeway to small-interest articles in because we have nearly infinite resources, or do you hold everything to the rules?  Personally, I lean more toward keeps than deletes, except for extreme cases.

In any case, I Rictor may pass for GA.  You can check out a similar character I worked on and moved to GA (Anole (comics)).  That really go there because I trimmed through FCH, and had a lot of third party sources on some plot lines that involved him and the character's creation.  The layout for an FA article would probably cut through a lot of character history and focus on publication history.  It offends some people to see what they consider "notable character history" cut, but if you want an accessible article, you have to do it.  Superman arguably has a ton of character history, but it's really just distilled down to the basic iconic things that others write about: Krypton, orphan, country boy, Metropolis, Louis Lane, Lex Luther, Justice League, etc.  I'm trying to find the time to do the same to Jean Grey.  I populated her Publication History, and that means ripping out a lot of that enormous Character History section.  Just some musings.
