Elements of feminism are present throughout much of Whedon's work and he gives his mother credit for inspiring this. The character Kitty Pryde from the "X-Men" comics was an early model for Whedon's strong teenage girl characters. He said, "If there's a bigger influence on Buffy than Kitty, I don't know what it was. She was an adolescent girl finding out she has great power and dealing with it." Kitty Pryde later played a central role in Whedon's run on "Astonishing X-Men". In his 2006 Equality Now address, Whedon said that journalists frequently ask him why he writes such strong female characters. In his speech he provided several answers, concluding with, "Because you're still asking me that question."
