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.
