In addition, because some meta-human criminals have the power to see through solid objects, Batman lines the cowl with lead to protect his identity. One of the cowl's ears carries a high-gain antenna for an internal comm-link on the left side of the cowl, allowing Batman to stay in contact with his allies. The comm-link can also scan police radios and other communication frequencies. It also carries an inertial navigation unit to keep him in balance when facing foes such as the Scarecrow or Count Vertigo.
In the "House of M", a Marvel crossover, the Scarlet Witch alters reality to make mutants the ruling class over humans. This world is ruled by mutants and their leader, Magneto. In the mini-series Spider-Man: House of M, Peter Parker is believed to be a mutant, and Spider-Man's identity is widely known. He is rich, famous and married to Gwen Stacy, and they have a young son named Ritchie. Aunt May and Uncle Ben are alive and in good health, and J. Jonah Jameson is Peter's often-abused publicist. Unfortunately, his life unravels when Jameson reveals to the world that Spider-Man is not a born mutant. After the world is restored to normal, Peter suffers terribly with the memory of the life he left behind, expressing a desire to kill Magneto, whom he mistakenly believes was behind the events of House of M, and the Scarlet Witch, whose powers were responsible for the altered reality. This version is later killed by Karn during the Spider-Verse event.
Today's Halloween customs are thought to have been influenced by folk customs and beliefs from the Celtic-speaking countries, some of which are believed to have pagan roots. Jack Santino, a folklorist, writes that "there was throughout Ireland an uneasy truce existing between customs and beliefs associated with Christianity and those associated with religions that were Irish before Christianity arrived". Historian Nicholas Rogers, exploring the origins of Halloween, notes that while "some folklorists have detected its origins in the Roman feast of Pomona, the goddess of fruits and seeds, or in the festival of the dead called Parentalia, it is more typically linked to the Celtic festival of Samhain, which comes from the Old Irish for 'summer's end'."
In the late 1980s and early 1990s, theme parks entered the business seriously. Six Flags Fright Fest began in 1986 and Universal Studios Florida began Halloween Horror Nights in 1991. Knott's Scary Farm experienced a surge in attendance in the 1990s as a result of America's obsession with Halloween as a cultural event. Theme parks have played a major role in globalizing the holiday. Universal Studios Singapore and Universal Studios Japan both participate, while Disney now mounts Mickey's Not-So-Scary Halloween Party events at its parks in Paris, Hong Kong and Tokyo, as well as in the United States. The theme park haunts are by far the largest, both in scale and attendance.
Most of the supervillains of Spider-Man would be introduced in The Amazing Spider-Man comic book starting with the Chameleon. The early villains would be introduced in the 1960s in the Silver Age of Comic Books, and created by Stan Lee and Steve Ditko. John Romita, Sr. replaced Ditko starting with the Rhino. Gerry Conway later replaced Stan Lee and helped create new adversaries for the web-slinger and also helped pave the way to the Bronze Age of Comic Books with the death of Spider-Man's long time romantic interest, Gwen Stacy. Many collaborators would soon take over The Amazing Spider-Man title. One of the more popular examples included Todd McFarlane's Venom in the Modern Age of Comic Books.
From at least the 16th century, the festival included mumming and guising, which involved people going house-to-house in costume (or in disguise), usually reciting verses or songs in exchange for food. It may have originally been a tradition whereby people impersonated the Aos Sí, or the souls of the dead, and received offerings on their behalf. Impersonating these beings, or wearing a disguise, was also believed to protect oneself from them. It is suggested that the mummers and guisers "personify the old spirits of the winter, who demanded reward in exchange for good fortune". F. Marian McNeill suggests the ancient pagan festival included people wearing masks or costumes to represent the spirits, and that faces were marked (or blackened) with ashes taken from the sacred bonfire. In parts of southern Ireland, a man dressed as a Láir Bhán (white mare) led youths house-to-house reciting verses—some of which had pagan overtones—in exchange for food. If the household donated food it could expect good fortune from the 'Muck Olla'; not doing so would bring misfortune. In 19th century Scotland, youths went house-to-house with masked, painted or blackened faces, often threatening to do mischief if they were not welcomed. In parts of Wales, men went about dressed as fearsome beings called gwrachod, while in some places, young people cross-dressed. Elsewhere in Europe, mumming and costumes were part of other yearly festivals. However, in the Celtic-speaking regions they were "particularly appropriate to a night upon which supernatural beings were said to be abroad and could be imitated or warded off by human wanderers". It has also been suggested that the wearing of Halloween costumes developed from the custom of souling, which was practised by Christians in parts of Western Europe from at least the 15th century. At Allhallowtide, groups of poor people would go door-to-door, collecting soul cakes – either as representatives of the dead, or in return for saying prayers for them. One 19th century English writer said it "used to consist of parties of children, dressed up in fantastic costume, who went round to the farm houses and cottages, signing a song, and begging for cakes (spoken of as "Soal-cakes"), apples, money, or anything that the goodwives would give them". The soulers typically asked for "mercy on all Christian souls for a soul cake". The practice was mentioned by Shakespeare his play The Two Gentlemen of Verona (1593). Christian minister Prince Sorie Conteh wrote on the wearing of costumes: "It was traditionally believed that the souls of the departed wandered the earth until All Saints' Day, and All Hallows' Eve provided one last chance for the dead to gain vengeance on their enemies before moving to the next world. In order to avoid being recognised by any soul that might be seeking such vengeance, people would don masks or costumes to disguise their identities". In the Middle Ages, statues and relics of martyred saints were paraded through the streets at Allhallowtide. Some churches who could not afford these things had people dress as saints instead. Some believers continue the practice of dressing as saints, biblical figures, and reformers in Halloween celebrations today. Many Christians in continental Europe, especially in France, believed that on Halloween "the dead of the churchyards rose for one wild, hideous carnival," known as the danse macabre, which has often been depicted in church decoration. An article published by Christianity Today claimed the danse macabre was enacted at village pageants and at court masques, with people "dressing up as corpses from various strata of society", and suggested this was the origin of Halloween costume parties.
