X-Men Wiki


Cassandra Webb was born in Salem, Oregon. She is a paralyzed, blind, telepathic, clairvoyant, and precognitive, allowing her to work as a professional medium. She was originally stricken with myasthenia gravis, a baffling disease that gradually erodes the central nervous system, and was connected to a life support system designed by her husband Jonathan Webb, which included a series of tubes shaped like a spider-web. She divined Spider-Man's secret identity, and used her powers to help him locate and rescue Daily Globe publisher K.J. Clayton. In "Nothing Can Stop the Juggernaut," she contacts Spider-Man for assistance when Black Tom Cassidy dispatches the Juggernaut to capture her in the hope that her psychic powers would help them defeat the X-Men, only for her to nearly die after Juggernaut separated her from her life-support system and Juggernaut to subsequently be trapped in a vat of wet cement. She apparently lost her memory of Spider-Man's secret identity. She is also the grandmother of the fourth Spider-Woman, Charlotte Witter. She participated in an arcane ritual known as the "Gathering of the Five", gaining immortality; she was restored to youth and had her myasthenia gravis cured. At one point in time Webb served as a mentor of sorts to the third Spider-Woman, the young Mattie Franklin, though Mattie has retired as of late. Madame Web has resurfaced and her psychic powers are intact after Decimation. However, since House of M (in which she did appear young) she seems to have regained her aged appearance, though the myasthenia gravis remains gone; this could indeed be taken as an effect of Decimation. Madame Web again returns in a back-up feature in Amazing Spider-Man #600. She looks into the future, showing what are apparently quick looks into Spider-Man's future, only to see someone "unravelling the web of fate", and fearfully exclaiming "They're hunting spiders". After that, she is attacked by Ana Kravinoff and her mother, who incapacitate her, and then claim "we now have our eyes". She is seen still captured by Ana and her mother, as they inspect their new quarry, Mattie Franklin. She apologizes to an unconscious Mattie while still bound in a chair.
