10. Kasumi (Dead or Alive)

When it comes to highly skilled lady fighters, looks can be deceiving. Take Dead or Alive's Kasumi for example. At 5'2 and 106 lbs she doesn't look threatening at all, she's freakin' hot. That's your first mistake, right there. Never underestimate your opponent, she may be cute and sweet but as the 18th Master of the Mugen Tenshin Ninja Clan, she's out of your league. Even though Kasumi is the most attractive Ninja you'll ever see, she has issues, the least of which include assassins and unrelenting attempts on her life ever day. Besides, even if you did have the fortune of hooking up with such an athletic little hottie, it probably wouldn't take long for one of those stray shurkins to get lodged in you head.
