In Better Call Saul, Ignacio Varga’s nickname is Nacho.
Nacho is the shortened form of Ignacio, and the series consistently uses it as his criminal-world name. He is introduced as a member of the Salamanca organization, although his ambitions and loyalties differ sharply from those of the family’s most violent members.
Michael Mando plays Nacho across the series. The character is notable because he is caught between cartel power, his concern for his father Manuel, and his desire to escape the drug trade. Viewers sometimes confuse Nacho with Lalo Salamanca because both become central Salamanca-related characters, but Nacho is not a Salamanca family member.
The name also appears in the character’s full name, Ignacio Varga, which is the canonical form used in episode credits and reference material.
