Claressa Shields is a 2-time Olympic gold medal winner and the first American boxer to win consecutive Olympic medals. She is a 5-division boxing champion. She is one of only four boxers in history to hold all four major world titles in boxing in two weight classes. She has won all of her 15 fights thus far with three knockouts under her belt, or belts. She currently doesn't have a fight scheduled as of the day this topic was posted but her next opponent definitely needs to be prepared. She claims to be the GWOAT (greatest woman of all time) but Laila Ali was 24 - 0 at the time she retired with 21 knockouts so that's up for debate.
