The Menace Of...MYSTERIO!
1st appearance "AS" "MYSTERIO" (Quentin Beck)
Reports of Spider-Man robbing various establishments at night hit the news, causing Peter to wonder if he's developed multiple personality disorder and goes on crimes sprees in his sleep as Spider-Man. He decides to go see a psychiatrist, however changes his mind about getting help as Spider-Man believing that it may compromise his secret identity.
Later, Peter goes to visit J. Jonah Jameson for a loan so that his Aunt May can make her mortgage payment on time. When there he snaps at Betty when she asks him why he hasn't taken any pictures recently, and Jameson rejects his request for a loan and tells him to go out and take more pictures. When Peter tries to find some crimes to photograph as Spider-Man, he only succeeds in getting an angry mob after him. Later at school Liz Allen tries to impress people with her new hair style, and she snubs Flash Thompson when he comments that her new look is so beautiful that he didn't recognize her.
Meanwhile, at the Daily Bugle, a new costumed being named Mysterio appears and tells Jameson that he's a crime fighter and that he will bring Spider-Man to justice. He vanishes in a puff of smoke and leaves a note for Jameson telling him to publish a challenge to Spider-Man to meet on the Brooklyn Bridge. Peter decides to meet this challenge, and is easily defeated by Mysterio who appears to have magical powers.
The next day Mysterio is heralded as a hero, and later when he appears at the Daily Bugle building for a photo opportunity with Jameson, Peter tags Mysterio with a Spider-Tracer finding him suspicious.
Tracking Mysterio to his base, Spider-Man is told by Mysterio that he is a special effects artist who has decided to turn his skills to crime and that he reproduced Spider-Man's abilities artificially in order to frame him for the crimes he committed. Spider-Man then reveals to Mysterio that he recorded the whole confession. A battle ensues, and Spider-Man uses his Spider-Sense to his advantage when Mysterio fills the room with smoke.
With Mysterio turned over to the police, Jameson realizes that he's been made a fool of again. However, when he finds that Parker has brought him pictures of Spider-Man's fight with Mysterio, his mood changes. Later Spider-Man pays another visit to Jameson and strings him up from his office's ceiling and mocks him for once again making a fool out of himself with his anti-Spider-Man press.
