fighting the Jack O'Lanterns. During the "Sinister War" storyline, Jack O'Lantern was with Foreigner, Taskmaster, Black Ant, Chance, and Slyde when they are sent by Kindred to attack Spider-Man after Kindred had disrupted their armored car robbery. Mad Jack There were two people who assumed the Mad Jack alias while wearing the Jack O'Lantern costume: Former Mysterio Daniel Berkhart was approached by Norman Osborn providing a version of the Jack O'Lantern costume, under the "Mad Jack" alias. Under Osborn's orders, Berkhart kidnapped John Jameson and exposed to mind-altering chemicals to be turned into a mind controlled pawn: the super-powered wolf alter-ego persona Man-Wolf. Jameson was then sent to attack J. Jonah Jameson, to terrorize and cow into being subservient towards Osborn's scheme to buy the Daily Bugle. During this time, he also stalked Jameson's wife, Marla, implying that the two had a past relationship that Berkhart sought to rekindle. After Berkhart's working relationship with Osborn ended when the Green Goblin participated in a magical ritual that rendered him completely insane, Berkhart was then approached by Maguire Beck, the female cousin of Quentin Beck (the original Mysterio). Maguire convinced Berkhart to re-assume the Mysterio identity following her cousin's suicide and the "Mad Jack" costumed identity was retired.

Jonah Jameson and several other mutual enemies, the two revived the "Mad Jack" persona, with Maguire using holograms and lifelike robotic versions of Mad Jack and Berkhart himself to serve as proxies for herself while she laid in secret. In the end, Maguire was caught and exposed though due to her usage of Berkhart androids but Daredevil and Spider-Man were left unsure as to whether or not Berkhart was truly involved. However Berkhart did ultimately escape with a Mysterio costume, in the confusion at the end.

The seller, Kingpin, said he had acquired the arsenal "from Jack-O-Lantern".
