Joaquín Guzmán Loera, otherwise known as "El Chapo" ("Shorty") was the head of the Sinaloa Cartel in Mexico. The man may have gained his nickname for being short, but he was larger than life. He was consistently ranked by "Forbes" magazine as one of the most powerful people in the world, and had a $5 million bounty on information leading to his capture.
Guzmán actually sparked the violent Mexican Drug War by ordering an assassination. He also managed to escape prison by hiding in a laundry basket. Before being arrested again in 2014, Guzmán was responsible for importing the majority of illegal drugs into the United States and was worth over $1 billion.
