The metaphor is the story, not the character.

I'm not building each one character around one metaphor, so much as trying to build a heroic archetype that can be used to express the kind of metaphors that I find in each story.

The characters are, by their nature, archetypes that can serve different metaphors.

If there's ever a character who can only serve one metaphor, I'll probably tell one story with that character and be done with it.
