It defiantly depends on the wiki in question how you categorize. You mention main characters with very large categories. True, but not in my case as we have four separate generations of characters each with their separate categories. I also see you have problems with individuals adding a photo with two characters into a category for one. To prevent this, we have different categories for images with more than a single character dependent of the other characters in the image. Minor characters have a single category for each generation. All of these factors create medium sized categories (about 30 to 70 images average) which are easier to look through. Easier is subjective though.

As for your example, if there are many, many images for your main characters, I would personally get rid of a category for the character. You mentioned levels and missions. If there are a number of images for these I would add all images for a specific level or mission (or weapon) into one category. This would also solve your problem with users applying categories to images with more than one character how you described. The categories would also be smaller (I'm assuming since I don't know the size of the levels/missions) and people who are interested in a single level/mission can check the category to see what was added and vice versa.

The category tree I set up makes locating what is and isn't on the wiki fast: Navigation.
