The Green Goblin is one of the most iconic supervillains in the Spider-Man universe. Created by writer Stan Lee and artist Steve Ditko, he first appeared in The Amazing Spider-Man #14 in 1964. Known for his green costume, glider, and pumpkin bombs, the Green Goblin is the alter ego of Norman Osborn, a wealthy industrialist who becomes a dangerous foe to Spider-Man due to his insanity and obsession with power. As a character, the Green Goblin embodies the duality of man, representing both the genius and madness that can exist within a single individual. His complex relationship with Spider-Man often blurs the lines between hero and villain, making him a compelling figure in comic book history.
