Gosh--I love reading all the different things other writers are doing in regard to character!
I've another trick of the trade I picked up from an actor who's played a lot of villains. He said they're easy to do, kick a dog and everyone hates you, right? (S. King went into "overkill" on this when he introduced his baddie in one book kicking the dog to death. At that point I simply stopped reading, so careful on too much of a bad thing until you're a multi-mega-seller. And even then. I stopped reading King altogether!
)
It's easy to make a baddie, said my friend, but making him likeable? Find something about him
you like
. He discovered that one really awful big bad he played had a really silly giggle for a laugh.
As for your good guy--find something about him that you just
hate. (Or it at least makes you wince.) They all need a weakness, they all need a strength.
As before, we all love Sherlock Holmes, but he could have been an excellent bad guy. Can you imagine trying to be
his roommate? Watson should have gotten a medal. Brilliant as Holmes was he had a coke habit, did stinky chemical experiments, kept strange hours, smoked like a truck, played his violin whenever he pleased, and was an utter slob. Come to think of it he reminds me a lot of a roomie I once had! (I kicked him out.) His saving grace was his brain (and paying his share of the rent--my roomie did not).
Can you imagine sharing a house with any of your characters? What would it be like with any one of them? Do they live in a crappy studio apartment or a Lex Luthor-style mansion? What kind of upbringing did they have? Who are their relatives? Who phones them? A meddling mom or bill collectors? Pets? Allergies?
Not all of this goes into your story. Many writers do a Tom Clancy data dump on page one--which is a major turn off for me as a reader. No one cares for a whacko stranger coming up and delivering his life story in a nutshell at a party--same deal goes for introducing your character to the reader.
Try going through a rack of books at the store, one after another down the line in the genre you want to write in and just read the first sentence of each book. The first and no more. Make note of which ones make you want to read further. Those writers are on to something, and chances are it's to do with their characters grabbing your interest.
