Isobel Aguirre was a reporter who covered some of the cases of the Fantastic Four, introduced in 1998. She was last seen investigating the history and background of Doctor Doom. She traveled to the monastery of the so-called "Monks of Doom", the creators of Doom's original armor, to find answers to one vital question: why did these men of peace involve themselves with a would-be dictator? On arrival, Isobel found most of the monks slaughtered and the few survivors being captives of the Crucible.

Crucible turned Isobel to a human gargoyle. Her face remained composed of living flesh but the rest of her body turned to stone. Crucible attempted to get her to swear allegiance to him in exchange for release. Her subsequent fate is unknown.
