In Better Call Saul, what is Lalo Salamanca's first name?

Lalo Salamanca's first name is Eduardo.

Eduardo “Lalo” Salamanca is a member of the Salamanca family and a major antagonist in Better Call Saul. He is introduced as a charismatic, observant, and highly capable cartel figure who takes an active interest in the Salamanca business and in Gus Fring's operations.

“Lalo” is a familiar form of Eduardo, which is why characters usually call him Lalo rather than Eduardo. He is distinct from Hector Salamanca, his uncle, and from Marco and Leonel Salamanca, his cousins. Tony Dalton portrays Lalo, whose calm manner and investigative skill make him one of the most dangerous figures in the series.
