El Profesor
Identity: The mastermind of the heist who assembled the group, and Berlin's younger brother
Background: The Professor, real name Sergio, mostly grew up in hospitals due to being a sick child. He leads the gang, and is the one who carefully plans and organises the heist in the Royal Mint and the Bank of Spain. He is sophisticated but nerdy. The idea of the first heist is to avenge his father, whose idea it originally was. His grandfather had fought against the fascists in Italy. He was the mastermind behind the plans of the two heists. He controlled the heist through a hiding outside the Royal Mint. The Professor falls in love with Raquel Murillo, a police investigator leading the case against the heist. Under the false identity of Salvador "Salva" Martín, he was able to get closer to the lead inspector assigned to the Royal Mint robbery, Raquel Murillo, and the pair eventually fell in love. Raquel then joins the gang by the name "Lisbon". He sleeps with her and when her mother finds out about his involvement with the heist, he attempts to poison her but pulls out at the last second, opting to take advantage of her poor memory and deleting the voicemail. The Professor spent years of his life meticulously planning the heist, and covered aspects that most people wouldn’t think of. His tactic was to lead the police to several dead ends to buy more time for the money to be printed and the team to escape.
