2. Cristiane “Cyborg” Santos (MMA record: 10-1)

“Cyborg” is an appropriate nickname for the current reigning Strikeforce women’s middleweight champion. To put it simply, Santos is dominating her division in a way that would make Wanderlei Silva’s reign in PRIDE look like child’s play.

You can’t help but feel bad for her previous victims and the poor ladies who are going to have to fight her in the near future. She’s knocking out everyone in sight and isn’t showing signs of slowing down anytime soon.
