Spier-Man (Peter Benjamin Parker) is a fictional character, a Marvel Comics superhero, created by writer-editor Stan Lee and artist Steve Ditko. The character first appeared in Amazing Fantasy #15 (Aug. 1962), and has since gone on to become one of the most popular, enduring and commercially successful superheroes worldwide, and is arguably Marvel's most famous character. When Spider-Man first appeared in the early 1960s, teenagers in superhero comic books were usually relegated to the role of sidekick to the series' main character. The Spider-Man series broke ground by featuring Peter Parker, a teenage high school student to whose "self-obsessions with rejection, inadequacy, and loneliness" young readers could relate. Unlike previous teen heroes such as Bucky and Robin, Spider-Man did not benefit from adult mentors like Captain America and Batman and had to learn for himself that "with great power comes great responsibility".
