Mysterio

Mysterio is another of Spider-Man's most famous and formidable rogues, and is ripe for live-action adaptation, especially now that general audiences have grown more accepting of outlandish concepts in superhero films. Quentin Beck is a special effects whiz and stunt man who turns to a life of crime following countless rejections in Hollywood, using elaborate (and often humorously creative) illusions and hypnosis. He's constantly foiled by Spider-Man, but is the kind of low-level threat that this new franchise needs, as Kevin Feige hopes to lower the stakes so that Peter Parker isn't constantly tasked with saving the world. We've already seen Peter go up against physically imposing villains, but have yet to see him face anyone that truly challenges him mentally and psychologically. Mysterio is the perfect adversary for that.
