A Question of Character(s)

How often are your characters influenced by other media, either in direct inspiration or as a base template to extrapolate and 'grow' from?

For example in Becoming Robin Nicole is loosely based on an original character of mine from several years ago. The key differences are age and upbringing, and of course Raven Wing is based on Nicole.

A better example though, is Jennifer Baker, one of Robin's other friends. I wanted to create in Jennifer the unique combination of laid-back but wise that I had in a dear friend when I was Robin's age, that I've lost touch with for several years now.

Rather than modeling her after Katherine though, I took inspiration from, appropriately enough, a couple of Disney movies: specifically Johnny Tsunami and Rip Girls.

Jennifer is nothing like any of the characters in either of these movies (in Rip Girls, Sydney has never visited her home before where Jennifer goes back every summer, but that's the closest connection I can see), but both have a lot of heart (Or maybe I'm just overly-sentimental :-P) and gave me a lot of indirect inspiration for the character I wanted to craft.

So, what are your thoughts?
