So I'm working on a new urban fantasy. And I've discovered I can't really move forward with the plot until all of my characters are fully created. And since I have thirteen characters, it's become quite daunting. Before you get all "that's too many characters" on me, let me explain. The story is a twisted, demonized version of the tv show The Bachelor. A demon kidnaps ten women, who he locks in his house and puts then through a series of trials and tests to figure out which one is the one he wants to marry. Two of the girls are going to be eliminated early, so I don't need to develop them as thoroughly. And two friends of the demon are only minor and are basically done. Two of the main characters are also basically done. So I really only need to build on seven characters. They won't be major roles, so I don't need to develop them as strongly as the main characters. But since all the women will be spending a lot of time together, locked up in one room, there's going to be some heavy interaction between them. Now, I know how to build a character. I do the interviews and use development sheets and whatnot. My problem currently is that I have so many, it's becoming difficult to make them all interesting and different. I'm finding that they all become very similar when I write down the basics. One of them is naive and sweet, another is sweet and quiet, another is quite but cruel, etc. They all just start blending together. So what do you do in this situation? Do you look at character tropes? Do you have special guides or worksheets that you use? Any advice would be appreciated.
