Most Prominent Latin American Champion

Who was the most noteworthy Latin American Champion ever? By "Latin American" I don't mean of Latin descent like US-born Oscar De La Hoya or Carlos Palomino, but actually born in Latin America. Listed on the poll are champions (some legends, some dominant in their era, all retired) who captured the imagination of the boxing world in their prime. If you can think of a more celebrated (unlisted) Latin champ, check "other" and say who.
