James. Jonah Jameson first appeared in The Amazing Spider-Man #1 back in March 1963 and has become one of the most famous non-superhero or supervillain characters in the Marvel universe. Portrayed mainly as the editor-in-chief of the Daily Bugle in the heart of New York City, Jameson is known for being brash, dubious and selfish in his work and has turned up as one of Spider-Man's biggest adversaries over the years.
Whilst his hatred of Spider-Man grew from a fairly legitimate fear of vigilantism rising across the city, his true personality eventually showed that this hatred was more of a personal vendetta against the web-crawler, rather than an open argument against a mask-wearing vigilante running across the Big Apple.
Jameson is a complex character, capable of showing flashes of immense self-sacrifice - such as not turning over Peter Parker's identity to the Green Goblin in Sam Raimi's trilogy - but constantly doing all he could to undercut and push through his headline stories, even if they weren't exactly well fact-checked or viable for publishing.
For Jameson, bringing Spider-Man and all who associate with him to heel is what drives his actions. It seems like there is no avenue he won't exploit a story or crush a spider, so here are the worst things J. Jonah Jameson has ever done.
