Willow Rosenberg, the OG (original geek) of the Whedon world, googled before it was a verb. Starting out first as just a ridiculously computer-savvy student (in high school, she was hacking into local police files and later graduated to secret government databases), she let no new advance in tech go undiscovered, and used it all for the greater good. In Buffy the Vampire Slayer, the Scooby Gang relied on her computer skills and technical know-how to save the world multiple times, and later, she used the same smarts to hone her witchy ways, becoming one of the most powerful Wiccas in the world. Plus, we are pretty sure she was the first person to discover Internet dating back in the '90s, though unfortunately, her match turned out to be a demon. Hey, we’ve all been there.
