Yoshida Saori
Yoshida Saori, JapanPossibly the most dominant athlete in the entire Olympics, Yoshida Saori is a female Japanese wrestler who has won every single world and international tournament since her debut in 2002. She's barely even lost a single match. She took gold at the Olympics in both 2004, and 2008, and she had a 119 match winning streak going until she was defeated once in 2008. Saori has rebounded from that loss though, and will defend her gold medal later this month in London. [Photo via]
