People sometimes have trouble defining who they truly are. Factors such as race, gender, culture, country origin, sexuality and occupation can all play a role in a person's identity. But when these things come into conflict with one another, a person may feel as if they are torn inside. They may feel as if they have two separate identities, or that their identity is divided into multiple facets. Characters in fiction are no different. They too can sometimes suffer from a clash of identities. The superhero for example that must live double lives; one as a hero and the other as a normal citizen.
