#2 Maria
How ironic is it that we follow Nikki Bella's entry up with someone she probably still despises to this day. Maria Kanellis has done some phenomenal work in both TNA and ROH over the last few years, proving that she was so much more than just a pretty face, which is exactly what WWE painted her as.
Still, she was there for quite a while, so she must have been doing something right.
During her time with the company, she was even involved in one of the more interesting mixed tags of recent times, and she joined forces with Cena to go up against Edge and Lita. It was one of the more fascinating versions of the concept because at the time, not a lot of people thought Maria could wrestle beyond 30-45 seconds.
Still, it was pretty entertaining. We conclude with potentially the greatest female wrestler of all time.
