Spider-Man is zombified by Captain America. Unlike many of his zombie compatriots, Spider-Man is consumed with guilt over his need to eat flesh, though he is unable to prevent himself from satiating his hunger. He later eats Galactus, and becomes one of The Galactus, a number of heroes who obtain Galactus' powers due to consuming him. When his hunger begins to fade he turns on his fellow zombies, and later travels to Earth Z, where he kills the Sinister Six. He makes attempts to find a cure and succeeds, filling Sandman with nanobites and using him to wipe out all zombies, including himself.
An early 1970s Spider-Man story led to the revision of the Comics Code. Previously, the Code forbade the depiction of the use of illegal drugs, even negatively. However, in 1970, the Nixon administration's Department of Health, Education, and Welfare asked Stan Lee to publish an anti-drug message in one of Marvel's top-selling titles.:239 Lee chose the top-selling The Amazing Spider-Man; issues #96–98 (May–July 1971) feature a story arc depicting the negative effects of drug use. In the story, Peter Parker's friend Harry Osborn becomes addicted to pills. When Spider-Man fights the Green Goblin (Norman Osborn, Harry's father), Spider-Man defeats the Green Goblin, by revealing Harry's drug addiction. While the story had a clear anti-drug message, the Comics Code Authority refused to issue its seal of approval. Marvel nevertheless published the three issues without the Comics Code Authority's approval or seal. The issues sold so well that the industry's self-censorship was undercut and the Code was subsequently revised.:239
Halloween costumes are costumes worn on or around Halloween, a festival which falls on October 31. An early reference to wearing costumes at Halloween comes from Scotland in 1585, but they may pre-date this. There are many references to the custom during the 18th and 19th centuries in the Celtic countries of Scotland, Ireland, Mann and Wales. It has been suggested that the custom comes from the Celtic festivals of Samhain and Calan Gaeaf, or from the practise of "souling" during the Christian observance of Allhallowtide. Wearing costumes and mumming has long been associated with festivals at other times of the year, such as on Christmas. Halloween costumes are traditionally based on frightening supernatural or folkloric beings. However, by the 1930s costumes based on characters in mass media such as film, literature, and radio were popular. Halloween costumes have tended to be worn mainly by young people, but since the mid-20th century they have been increasingly worn by adults also.
