Developing a fully formed character is probably one of the hardest things for a writer to do. Creating a believable character involves incorporating realistic characteristics in your character. Below are some prompts that will help you write believable characters:
Someone You Love
Write down the name of a person you love. Write down a list of all this person’s characteristics, both good and bad. After you have written all of the characteristics down, write down the opposite of each characteristic you have already written. For example, if you wrote that the person is exciting then place dull next to it. Write a short story about this new character who is literally the exact opposite of your loved one.
Create a character around this one sentence. I am 42 and I have never been married. Who is this character? Is it male or female? Has he ever been in love before? Or is she a woman with an impossible list that no man could ever measure up to?
In the Face of Evil
Write about a character who has committed an unspeakable crime. This character should have committed a crime that most people would find inexcusable. Now that you have the character, make him sympathetic in some way. Make your readers pity him.
