Spider-Man is a fictional Marvel Comics superhero. The character was created by writer-editor Stan Lee and writer-artist Steve Ditko. He first appeared in Amazing Fantasy #15 (Aug. 1962). Lee and Ditko conceived of the character as an orphan being raised by his Aunt May and Uncle Ben, and as a teenager, having to deal with the normal struggles of youth in addition to those of a costumed crime fighter. Spider-Man's creators gave him super strength and agility, the ability to cling to most surfaces, shoot spider-webs using devices of his own invention which he called "web-shooters," and react to danger quickly with his "spider-sense", enabling him to combat his foes.
