This allows him to play a tense game of one-upmanship with Inspector Raquel Murillo, where he repeatedly manages to shift the status quo in favor of his team during the heist, despite overwhelming odds.

A majority of his plans gravely depend upon the reactions he predicts from the police, the government, and the public.

He also demonstrates a deep understanding of human psychology. He was able to control the entirety of the heist from behind the scenes, playing with the police and constantly tricking them into doing exactly what he wanted them to do. The Professor appears to have exceptional knowledge in negotiation tactics, police strategy, weaponry, law enforcement, hostage crises aversion, forgery, theft and bank robberies. This forward-thinking approach helps him in his strive for perfection, where he urges the team to 'stick to the plan' in every situation. His perfectionist attitude is apparent through his careful consideration and planning for all possible scenarios that could arise during the heist. Once he recruits his dream team, he makes everyone religiously follow a strict schedule, complete with fundamental rules to prepare for and execute the heist. He appears to be very determined to pull off the greatest money heists in history, after planning for it for several years. Sergio is highly intelligent and meticulous. He is rarely seen without a formal suit, overcoat and tie, but has also been seen to don various disguises to avoid detection by police, eg. His gait portrays him as slightly confused, as he doesn't swing his arms when walking. His hair is long and black, and he cuts it slightly shorter in Part 3. Sergio is a male with a mustache and a beard in very good physical condition. This was a heist that he and his half-brother Berlin had planned years ago. The Professor led a second heist in the Bank of Spain, in an effort to pressure the Spanish government who had arrested Rio. Raquel then joins the gang by the name 'Lisbon'. Under the false identity of Salvador 'Salva' MartГn, 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. The Professor recruited 8 robbers to carry out a heist at the Royal Mint of Spain, a heist that his father had planned. At the age of 19, he stopped renewing his identity card, so that he would not be registered. The Professor had been planning heists from a young age.
