Halloween activities include trick-or-treating (or the related guising), attending Halloween costume parties, carving pumpkins into jack-o'-lanterns, lighting bonfires, apple bobbing, divination games, playing pranks, visiting haunted attractions, telling scary stories, and watching horror films. In many parts of the world, the Christian religious observances of All Hallows' Eve, including attending church services and lighting candles on the graves of the dead, remain popular, although elsewhere it is a more commercial and secular celebration. Some Christians historically abstained from meat on All Hallows' Eve, a tradition reflected in the eating of certain vegetarian foods on this vigil day, including apples, potato pancakes, and soul cakes.
In one possible future of the Marvel Universe, Advanced Idea Mechanics has examined the Uni-Power and attempted to duplicate it. The duplicate, referred to as the 'Alias-Power' or 'Uni-Alias', has the ability to animate the Death's Head 3.0 robot. While resident in Death's Head, it took the form of a conscience. On one occasion, when asked to rescue an evil scientist from a jail, it instead rescued a human rights activist. When the robot killed a UN researcher, the power brought him back to life. The researcher then confronted the robot, forcing it to acknowledge the conscience. Afterwards, Death's Head began working for the UN as an anti-terrorist hit-man.
In 1975 Shotaro Ishinomori's Himitsu Sentai Gorenger debuted on what is now TV Asahi, it brought the concepts of multi-colored teams and supporting vehicles that debuted in Gatchaman into live-action, and began the Super Sentai franchise (later adapted into the American Power Rangers series in the 1990s). In 1978, Toei adapted Spider-Man into a live-action Japanese television series. In this continuity, Spider-Man had a vehicle called Marveller that could transform into a giant and powerful robot called Leopardon, this idea would be carried over to Toei's Battle Fever J and now multi-colored teams not only had support vehicles but giant robots to fight giant monsters with.
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.
