No, that wikia's data isn't applicable because it's based off the comics and encompasses many of the different Marvel media vehicles. This wiki is only for the Avengers Academy game, therefore I removed your changes.
Hello! I see you've just created a new category for 'Humans'. Have you run this by the admin? Their policy on categories is to keep them to a minimum, especially ones that just describe characters, such as 'humans'.
Okay, I did some digging and here's a quote from the admin, Zepysgirl, regarding not creating new categories:
"Our rules with Categories are to keep things as simple as possible & stay with in-game groupings only. We add new categories for each new event and that's pretty much it. Over-tagging would just cause confusion."
I assume you mean you checked the Avengers Academy page on the Marvel Wikia? We are unrelated to them. We need to do what works best for us (a wiki for one specific game), which doesn't always line up with what works for them (a wiki for all Marvel's everything).
Adding character stories to the event pages seems like an awful lot of work with not much payoff? It would also clutter up those pages. I'm in favor of leaving the Category pages streamlined. But, as I said before, if you'd like to include more information about an event (be it the story or pictures)--that can go on the event's page itself.
