One of the keys is, and it may sound funny, talking about characters with super powers, but one of the keys is to make your characters as realistic and believable as possible. Even if they have super powers, you say to yourself, "Well, if somebody had a super power like this, what would his life be like? Wouldn't he still maybe have to go to the dentist or wouldn't he have to worry about making a living? What about his love life?" You've got to make characters that your reader can believe exists or might exist.
Stan Lee... And we talk it out. Lately, I've had Roy Thomas come in, and he sits and makes notes while we discuss it. Then he types them up, which gives us a written synopsis. Originally - I have a little tape recorder - I had tried taping it, but then I found no one on staff has time to listen to the tape again later. But this way he makes notes, types it quickly, I get a carbon, the artist gets a carbon ... so we don't have to worry that we'll forget what we've said.
Stan LeeWhat did Doctor Doom really want? He wanted to rule the world. Now, think about this. You could walk across the street against a traffic light and get a summons for jaywalking, but you could walk up to a police officer and say "I want to rule the world," and there's nothing he can do about it, that is not a crime. Anybody can want to rule the world. So, even though he was the Fantastic Four's greatest menace, in my mind, he was never a criminal!
