Molten Man’s First Appearance
In addition to Mysterio, Spider-Man: Far From Home contains four other villains created in the Spider-Man comics: Cyclone, Sandman, Hydro Man and Molten Man. While, in the movie, the characters are actually fictional creations of Quentin Beck, in the comics each of them was a very real threat. Cyclone is only seen briefly in the film, and if you’re a comic book fan, you likely caught the reference to the comic origin story of Hydro Man, but unless you like reading license plates very closely, you probably didn’t catch the Sandman and Molten Man references.
