As part of the Avengers, Spider-Man traveled to Latveria to investigate Doctor Doom's apparent attack on the neighboring country, Symkaria. Upon arrival, he and his fellow heroes found a dome-shaped structure emitting radiation and broke into it. Inside the building, they came under attack from automated laser turrets, and while Spider-Man was busy webbing them up and cracking jokes, he was suddenly electrocuted into submission and kidnapped by Runabout. When he regained consciousness, he found himself strapped to a table by a giant robot named Megatron, who explained that the hero was about to help him and his Decepticons conquer the world. Man and Machine, Part One Megatron began extracting Spider-Man's radioactive blood, refining it into a powerful energon isotope that he used to supercharge his troops. All Spidey could do was lay there and weakly taunt him. Man and Machine, Part Two
In Batman: Year One, it is depicted that Batman hid a few pieces of his arsenal in his leather boots, such as a blow gun with fast-acting anesthetic darts and an ultrasonic device built into his left heel. Batman's boots are highly unique. The basic design of the boots are modeled on Tactical boots, but they are made from lightweight rubbers and are much more flexible to allow for full extension when kicking. The boots feature a unique "slingshot" ankle reinforcement design that acts as both the armor and as reinforcement for the ankle joint when kicking or landing from high distances. The bottom is a flexible split sole design and is textured for a variety of surfaces. The boots also have steel toes, making them much more effective when on the offensive. Although Batman is already an accomplished Olympic level swimmer, during the Batman: Hush storyline, it is revealed that he installed underwater propellers on the heels. In Batman Begins, a boot heel is revealed to contain an ultrasonic signaling device capable of calling live bats to it as a form of protection and cover for Batman during a getaway. This device was originally introduced in the Batman: Year One series.
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.
