New story? Who shall it be?

So I have an idea of what I want the story to be like. It probably will be finished by the end of summer if I start it within the next week or so. The story line and everything is decided but there's something missing. Who should the main character be? I was thinking Jon Walker but if you have any suggestions on who you want to read about, I'd like to hear. Tell me if you want to see Jwalk or anybody else (Preferably someone I haven't already written about) in it. Feedback please? Some peolple said they want to read about Jon and that's who I was going to go with originally. If I don't get any comments on this, I'm just going to stick with Jon. So feel free to voice your opinions.
