#2 AJ Lee
This one is a bit of a cheat since AJ Lee being a nerd is not really a secret. When she first graduated from NXT--back when it was still a reality show and not the most fascinating brand in sports entertainment--the announcers were quick to point out that she was a comic book fan and self-professed geek.
While it's all true, it seems as if the WWE chose to emphasize her geekdom because they were afraid the fans wouldn't resonate with her because of her petite size. AJ Lee would go on to become one of the most successful women of all time, successfully bringing more athleticism and technical wrestling to the then-Divas division.
