Judo Princess, world champion

When she was just 12, Kayla Harrison gave herself a nickname: Judo Princess. It's still part of her email address. The princess fights tough. Now she's world champion.

At judo's world championships earlier this month in Tokyo, Kayla Harrison, now 20 years old, beat 19-year-old Mayra Aguiar of Brazil in sudden-death overtime to win the 78-kilogram (172-pound) division.
