The Museum of Television and Radio's Blog Potato site attempts to determine who would win in a fight: Wonder Woman or Buffy. I'm mostly linking because I agree with their assessment, but I also just love the idea that someone wrote up such a serious, analytical post on the topic.
Buffy never uses a gun, so Wonder Woman’s bracelets would do her no good. The invisible jet would only be useful for a quick escape. And the golden lasso of truth might pose the biggest challenge but could be dodged. So, that leaves us with a battle of strength. Link
