The facts are this:
1) The main villain in The Legend of Spyro: A New Beginning was based – loosely – after Dark Willow from Buffy, insofar as we knew she was good at heart and was twisted by evil magic. There was a lot more to it than that but we knew from the outset it was going to be a character Spyro could team up with in the sequels and I used Dark Willow a lot when it came time to crafting her dialogue and overall look.
2) The idea of Alyson Hannigan doing the voice of Cynder was kiboshed pretty quickly when we heard she doesn’t “do” video games.
3) And even if she did there’s no way in hell the game designer ever gets invited to the voice recording sessions. BAH I COULD HAVE MET GARY OLDMAN.
