He failed to do so, but did find out the superhero's secret identity, and hired the assassin Bullseye to murder Daredevil's girlfriend before Beck killed himself after battling Daredevil. Later in his life, Beck learned that he was dying of cancer, and decided to perform one last act by driving the crime fighter Daredevil insane. He once took the identity of a psychiatrist and nearly convinced Spider-Man that he had gone insane and to reveal his secret identity. Since then, Beck became a member of one of Spidey's main Rogues Gallery, several times battling the web-head solo, and also joining up with Doctor Octopus's supervillain team, the Sinister Six. He was dubbed a hero before Spider-Man fought him again and exposed his real intentions, resulting in him being arrested, Spider-Man's name being cleared and Beck plotting revenge against the Web Slinger. Mysterio soon battled Spider-Man, ultimately defeating and humiliating him through use of his many tricks and special effects. Jonah Jameson, who hated Spider-Man with a passion, agreed wholeheartedly, and supported Beck's stunt. Beck, realizing that his expertise in special effects would make him a capable supervillain, donned the role of Mysterio and went to the Daily Bugle newspaper, announcing that he would bring the hated Spider-Man to his knees. The original and current Mysterio was Quentin Beck, a special effects expert and stuntman who came to see his career choice as a dead end, his attempts at becoming an actor being met with poor reception. The original Mysterio's appearance in the early comic strips since The Amazing Spider-Man #13 in 1964.
