American historian and author Ruth Edna Kelley of Massachusetts wrote the first book-length history of Halloween in the US; The Book of Hallowe'en (1919), and references souling in the chapter "Hallowe'en in America". In her book, Kelley touches on customs that arrived from across the Atlantic; "Americans have fostered them, and are making this an occasion something like what it must have been in its best days overseas. All Halloween customs in the United States are borrowed directly or adapted from those of other countries".
After Bruce Wayne was defeated and crippled by Bane, he nominated Jean-Paul Valley to take up the mantle of Batman while he recovered. While initially wearing Bruce Wayne’s uniform, Jean-Paul would eventually begin to succumb to his “programming," becoming more and more corrupted by the crime he was fighting, and replaced the suit with his own tailor-made armour with razor disks, blades and hidden weapons, becoming a more aggressive and unstable Batman, known among comic-fans as the “Azbat” ("Azrael-Batman").
There have been controversial costumes over the years. One that sparked enormous controversy well before Halloween 2015 is a "Caitlyn Jenner" corset costume. Despite public outcry claiming that the costume is offensive, popular retailers plan to go full steam ahead with selling the costume; one defending their conviction to sell the costume as a celebration of Jenner.
