How do their respective species influence their behavior?
This is another concept I only became aware of after encountering furry fandom. I would have to say that I never explored this. My characters have always been metaphors for human personalities. It was never my intent to create characters that were entirely nonreplacable with human ones–so if that’s what you were looking for, look elsewhere. Since I haven’t written any stories with these characters, I haven’t had the oppurtunity to experiment with species-influenced behavior. However, I have not defined any personality aspects that rule out such influences, in the event someone wishes to corroborate with me to write any of these characters into a story.
