Hmm, that's an interesting suggested but I'm afraid I disagree. To me the purpose of categories is so you can find a character you don't know the name of, but also so it suggest other character with similar life choices. Like how all the X-men are grouped together. But also when a user doesn't know who they are looking for, like they know it's an x-men but not sure of the name. By clicking the 'x-men' category, they now can. Or if the character is a villain, or female and that's all they know etc.
