I can understand the temptation of a writer to make his characters the best they can possibly be. (I’m guilty.) After all, when making stuff up what’s the need for limits? Characters can be inhumanly gorgeous and have the best figure ever in any proportions one can imagine in order to make them perfect.
My question is, how plausible is a physically ideal character? Is it necessary for a character to have at least one physical flaw? Or, in your opinion, can his or her only flaw be a dark, evil heart, supreme idiocy, or other such undesirable inner workings?
