I wasn't really allowed to see mainstream movies until I was a 'tween. The original Star Wars was my first and so of course I identified with...R2-D2. Later I felt the same affection/identification toward Huey, Dewey and Louie from Silent Running when I saw it. If was a child of this era, it'd probably be Wall-e ...and a certain tinker-fairy who never seems to quite socially mesh with the others. Now, books...pretty much any capable female protagonist I could find. Sadly, my folks took away anything that had an obviously strong female main or even secondary characters. Television? Laura Ingalls. She didn't seem to mind solitude, got in trouble a lot, and often seemed to be part of things only by virtue of being there. Yet she was somehow separate from everyone else.
