The Avengers is a team of superheros in comic books published by Marvel Comics. Originally created using preexisting Marvel characters, variously created by writer-editor Stan Lee, artist and co-plotter Jack Kirby and others, the team first appeared in The Avengers #1 (Sept. 1963).
Spider-Man is a fictional Marvel Comics superhero. The character first appeared in Amazing Fantasy #15 (August 1962), and was created by scripter and editor Stan Lee and designed by artists and plotters Steve Ditko and Jack Kirby. Lee and Ditko conceived of the character as an orphan being raised by his Aunt May and Uncle Ben as an ordinary 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 the ability to cling to walls, 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 many foes, including Doctor Octopus, the Sandman, the Lizard, the Green Goblin and Venom and many others.
In 1961, Marvel Comics editor/writer Stan Lee, artist Jack Kirby and several other illustrators produced a number of superhero titles which stressed character personalities and personal conflict as much as action and adventure, including The Fantastic Four, The Incredible Hulk and Spider-Man. The X-Men was one of the last titles of this Silver Age renaissance, appearing in September 1963. In the comic book series, the X-Men were founded by the paraplegic telepath Charles Xavier, also known as Professor X. Xavier gathered the X-Men under the cover of a "School for Gifted Youngsters" at a large country estate at 1407 Graymalkin Lane in Salem Center, a city in Westchester County, New York.
