"McGarrett's mom, Hawaii Five-0
The Dirt: At first, McGarrett's mom was believed to have been killed in a car accident when Steve (Alex O'Loughlin) was just 16. It was later revealed that her death was no accident, but actually a homicide caused by Steve's dad's secret investigation into the powerful Yakuza gang. However, it was only after Big Bad Wo Fat was finally put behind bars at the end of Season 2 that the real truth was revealed by Joe (Terry O'Quinn): Not only is McGarrett's mom alive, but she's Shelburne, the only person Wo Fat feared. In the final moments of Season 2, Joe brought Steve to Japan to reconnect with his mom face-to-face.
The Role: Keeping in mind that she is the only person Wo Fat was afraid of, it's safe to say that Mrs. McGarrett is a bada-- with a capital B. Besides that? Details are scarce.
Our Pick: Just going on the fact that she's been rogue for the last 15-something years and that she was the only person Wo Fat feared, our top choice is one of the top female action stars of all time: Alien's Sigourney Weaver. Geena Davis, who showed off her impressive combat moves and shooting skills in films like The Long Kiss Goodnight and Thelma & Louise, would also be a good contender."
