Leonel and Marco Salamanca (commonly known as The Cousins) were twin brothers and hitmen for the Juárez Cartel, a Mexican drug cartel and villains in Breaking Bad. Despite an austere, mechanical physicality and virtually non-verbal interaction, they were a fearsome presence who killed without hesitation or emotion. They served as the main antagonists of the first half of Season 3. They were portrayed by Luis and Daniel Moncada, who are brothers (though not twins) in real life as well.
