J. Jonah Jameson is a character in the Spider-Man franchise. Sometimes he appears as sort of a villain and anti-hero, being obsessed with proving to the world that Spider-Man is a threat that must be handed over to the authorities at any cost as well as revealing his true identity to the public. However, as the years progressed, he was depicted in the comics as one who actually admires Spider-Man and even aids him.
He dislikes Spider-Man, though he had an affection for Peter Parker over the years.
J. Jonah Jameson was created by the late Stan Lee (who voiced him in Spider-Man: Into the Spider-Verse, in one of Lee's last roles before Lee's death) and the late Steve Ditko.
J. Jonah Jameson was born to David and Betty Jameson. His father was a United States Army officer and a veteran war hero. But David Jameson was an abusive man and would regularly beat his wife and son, which caused Jonah to grow up convinced that even heroes could be and indeed were evil. During high school Jonah was active in boxing and photography. When he joined the photography club he met Joan, who would eventually become his wife. When some bullies began bullying Jonah, he fought back and beat all of them. Joan was impressed and the two of them started dating soon after. They would marry after high school.
Conflict with Spider-Man
Although Jonah at first appeared to simply be a one-dimensional, raving tycoon with a grudge against Spider-Man, he has evolved over the years to show that he has a kind side too (notably towards his employees when he was in charge of the Daily Bugle, whom he would often side with and support), and that he has a myriad of deep, and arguably rational, reasons for his dislike and hatred of Spider-Man.
Jameson is always thwarted, embarrassed, and frustrated by Spider-Man. He hates the "costumed freaks" more than he's ever hated anyone before. He'll never be content while he's free. Initially, Jonah targeted Spiderman for taking much deserved media attention away from his astronaut son, and distrusts him for operating outside of the law. However, Jameson's hatred never blinds him or subtracts his integrity, as he always reported whenever his attacks on Spiderman's character was proven wrong and has helped Spiderman when he felt it was for the greater good.
Business and Family
Jonah became a journalist after he graduated from school. He found his first job at the Daily Bugle. During his time as a journalist he met the original Human Torch, Jim Hammond, and Namor MacKenzie, the Sub-Mariner, for the first time. Jameson, skeptical of both of them, refused to trust anyone whom he was convinced operated outside the law. During World War II, he went to Europe to cover the war.
After World War II, Jonah and Joan had a son, whom they named John. When the Korean War started, Jonah went out on the field to cover that war also. Eventually returning home, Jonah discovered that his wife had been killed by a mugger. Jonah became obsessed with his work in hopes of forgetting the pain the loss of his wife caused. Jonah worked so hard that he was eventually promoted to Chief Editor of the Daily Bugle. During his time as a reporter, Jonah had contributed in helping to bring down organized crime, and also supported civil rights.
