At the 2018 Winter Olympics, Fernández skated his "Modern Times" short program, executing a quad-triple toe loop combination, a quad Salchow, a triple Axel and all level 4 elements. He received nine perfect 10.00 scores in program components and received 107.58 points, placing him second in that segment behind defending champion Yuzuru Hanyu. In the free skate, Fernández landed a quad toe loop, a quad Salchow in combination, two triple Axels and five more triples, and earned four perfect 10.00 component marks. His only major mistake was popping a planned second quad Salchow into a double. His free skate performance earned 197.66 points and a total competition score of 305.24 – both season's best for him. Fernández won the bronze medal behind Japan's Hanyu and Shoma Uno, the first ever figure skating Olympic medal for Spain. In the figure skating gala, Fernández performed his aerobics class exhibition program wearing in a "Super Javi" Spanish-colored Superman costume.; the program included parodies of Flashdance and iconic 1980's workout jams.
