Mysterio is the name of three fictional characters, all of which are supervillains and enemies of Spider-Man in the Marvel Comics Universe. The original Mysterio (Quentin Beck) was created by Stan Lee and Steve Ditko and first appears in Amazing Spider-Man #13, although it was later retconned that the aliens seen in Amazing Spider-Man #2 had been Mysterio and his men in disguise; it was revealed that he had been hired by the Tinkerer to disguise himself as an extraterrestrial and uncover military and industrial secrets.
In 2009, Mysterio was ranked as IGN's 85th Greatest Comic Book Villain of All Time.
