Boxer Manny Pacquiao was an obscure fighter from the Philippines, when he first arrived in the U.S. in 2001. Since then, he has become a record-breaking champion boxer who has transcended the sport. Now serving as a congressman in the Sarangani province, Pacquiao may have an eye on the presidency of the Philippines.

Meantime, he's due to meet Mexico's Antonio Margarito in the ring on Saturday for the world junior-middleweight title fight at Cowboys Stadium.
