After I adopted the wiki, I changed the name to match the website address, so now the wiki is for more than just heroes. Any good guys are allowed, but be careful about saying a character is a hero when they really aren't.
Also, I am going to try and cut back on the number of categories on each page. A lot of times, people add categories instead of writing things about the character because it's easier to put an "arrogant" category on the page instead of showing how the character is arrogant. Please help out by not adding categories unless there are sentences on the page to support the categories.
I guess if we fall back to using the definition of protagonist that says "leading character" and push aside the rest of it that says "hero or heroine of a drama or other literary work", then it works better.
