Okay, the bare bones of the Wiki section is now up and running. I've got everything laid out into various categories, all in alphabetical order. Individual character pages have not been done yet (that's probably going to take the better part of the week considering how many characters have been played, and how many more have been used as NPCs).
I strongly ask you to create pages for your characters; to do that, you'll need to sign up for an account and follow the necessary steps for page creation, and please, please list them under the correct sections.
To avoid confusion with other games using the same characters, make sure you list your character with the (All-Star) suffix after it. So, Spider-Man would be listed as
Spider-Man (All-Star). From there, follow the page creation guidelines at the top of the Wiki.
