Here's some character break downs for season 3.
'Narcos': Boyd Holbrook Exits as Season 3 Reset Revealed
Gilberto Rodriguez Orejuela (Damian Alcazar) returns as the leader of Cali Cartel, the “boss of bosses,” and the rest of the Kings are Miguel Rodriguez Orejuela (Francisco Denis), Gilberto's brother and the brains behind the cartel's rise, Pacho Herrera (Alberto Ammann), the hitman who runs the Mexican connection and international distribution, and Chepe Santacruz Londono (Pepe Rapazote), who runs the satellite NYC empire of the Colombian drug network.
Other new players in the third season include Jorge Salcedo (Matias Varela), Cali’s head of security who prioritizes his wife and kids’ protection over his bosses;
previously announced DEA agents Chris Feistl (Michael Stahl-David) and Daniel Van Ness (Matt Whelan), who enter the operation with enthusiasm and inexperience; Franklin Jurado (Miguel Angel Silvestre), the cartel’s money launderer who unknowingly puts his wife,
Christina (Kerry Bishe) in mortal danger; and David Rodriguez (Arturo Castro), Miguel’s oldest son, who is reluctant at first to take a leading role in the cartel structure.
