Shego

Shego is one of the main antagonists of animated series Kim Possible. One of the more well-known characters of the franchise, she's infamous among internet circles for causing many a gay awakening, and as such, has landed a spot here as one of the premier tumblr sexywomen.

Basic Information
Shego's usual role in the show is as the muscle to Dr. Drakken (if you don't know him, think of him as a proto-Doofenshmirtz and you'll have a good idea of what he's like), serving as his main way to combat Kim Possible and her own sidekick Ron Stoppable. She's done work for other villains too, but rarely has actually struck out on her own, with the one time she does being Sitch in Time, where she successfully takes over the world in the bad future.

For more information, see her article on the Kim Possible wiki.
