Three former hosts of the Uni-Power—Susan Storm-Richards, Spider-Man and X-23—are all contacted by the Enigma Force once again when the Whirldemon King, a powerful entity once defeated by the time-traveling Prince Wayfinder of Ithaca and creator of the Enigma Force itself, escapes imprisonment. When X-23 sacrifices herself to save Valeria Richards from possession by the King the Uni-Power bonds with her a second time. While trapped in the Whirldemons' prison dimension, a connection is explicitly made between a starry apparition that enabled Laura to throw off the influence of a demon attempting to coerce her into serving it, when the star-shaped mark left on Laura's palm after that encounter is recognized by the Whirldemon King as associated with the Enigma Force. Laura then uses the Uni-Power to wound the Whirldemon King and seal him back in his prison dimension, before returning her to earth. During these events the Enigma Force tells Laura that she has been designated the future heir to its power.
Vacuum Seal: By pressing the emblem on the chest, Parker can expand the suit several sizes larger, allowing him to slip out of the suit easily. He can still wear undergarments under the suit because of its vacuum seal, which can also compress the suit to appear as though he is wearing nothing underneath. Once the vacuum seal compresses the suit properly, the suit's A.I. initiates and performs a diagnostics check.
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.
