SYDNEY, AUSTRALIA - MAY 11: Captain Ratz of Team Unicorn meets fans following Bout One of the Sydney Roller Derby League on May 11, 2013 in Sydney, Australia. The wildest thing on eight-wheels, these 'Warriors' of Roller Derby are jamming a blend of athletisim and pop culture through bumps, bruises, hip-whips, tattoos, fishnets and big characters as the fastest growing Women's sport on the planet, with over 1200 amatuer leagues worldwide. Originated in the mid 1930's as endurance skating, the modern revival of Roller Derby early in the 21st century can be artibuted to an all-female participation who share a strong 'do it yourself' ethic.
