 As part of a plan by Peter's arch-foe Norman Osborn, May was replaced by a "genetically-altered actress" who impersonated her while May was held captive by villains until the actress died, Osborn returning May to Peter with a device planted inside her that would detonate a series of gene bombs if removed, decimating Earth.Mister Fantastic was able to disable the device without removing it, saving the world and May, who apparently retained no memory of her time in captivity.May finally learned about her nephew's secret life when she walked into his room after he had sustained a serious beating from the villain Morlun, the two later talking about May's discovery as May came to accept her nephew's real life.
