What separates 'significance to story' and 'what they do'? I would think the two are usually a bit too interconnected to make separate categories, at least for most major characters.
Darth Vader's significance to story: Second in command of evil totalitarian empire. Ultimate baddie who needs to be stopped.
What Darth Vader Does: While he serves the emperor, he shows hesitation at the thought of killing his own estranged children. He kidnaps Princess Leia, kills an underling who mocks his belief in the force, etc, etc.
I wanted them separate as actions do not denote the part they play in the story (technically, you could write the same story and make him the hero, or a minor character who merely moves the plot forward like in Brazilian Star Wars.) Also, 'does' handles wants and thoughts, while 'significance' doesn't necessarily
However, you do make a good point of how they are interconnected and I do appreciated the post.
