In 'Money Heist', what is the code name of the mastermind?

In Money Heist, the code name of the mastermind is The Professor. His real name is Sergio Marquina, and he is portrayed by Álvaro Morte in the Spanish series La casa de papel, known internationally as Money Heist.

The Professor assembles and directs the gang behind the robberies of the Royal Mint of Spain and the Bank of Spain. Rather than joining the criminals inside at first, he coordinates the operations from outside, anticipating police tactics and preparing elaborate contingencies. His apparent weakness—being shy, physically unthreatening, and socially awkward—helps conceal how carefully he has planned the heists.

The character also uses the alias Salvador “Salva” Martín while approaching police inspector Raquel Murillo, who is investigating the Royal Mint robbery. That relationship becomes one of the series’ central storylines. Viewers sometimes confuse The Professor with Berlin, Tokyo, or Palermo, but those characters are members of the crew; The Professor is the strategist who organizes the overall plan.
