Gus is the head of one of the country's largest methamphetamine production/distribution operations in the United States. He enters our story when Walter and Jesse hunt for a large-scale buyer for their product and Saul connects them as a third-party.His front in Albuquerque is a small chain of fast food restaurants called Los Pollos Hermanos. Gus is highly secretive, preferring to maintain an almost comically low-profile for a person who is essentially a drug kingpin.We do not know much about Gus' origin, though it is believed his roots are somewhere in South America.
