Quentin Beck is a special effects wizard and stunt man working for a major Hollywood studio with dreams of making a name for himself in the film industry. However, he came to see his career in special effects as a dead-end job. His attempts to become an actor were poorly received, but he realized that his expertise in illusions could make him an effective criminal. In his first battle with Spider-Man, after he frames Spider-Man for robbing the Midtown Museum, Mysterio obstructs the hero's spider-sense with gas and dissolves Spider-Man's webbing with a chemical abrasive. However Spider-Man tricks Mysterio into revealing he robbed the museum, then Spider-Man revealed he had captured it on tape. Mysterio was then jailed, blaming Spider-Man for his ruined career.
