Though Cassandra Webb suffered from a lifetime of blindness and many years of neurological deterioration due to myasthenia gravis, she compensated with her profound psychic abilities, establishing herself as a medium.

When girlfriend Debra Whitman showed Peter Parker an advertisement for the psychic "Madame Web", he dismissed her as a fraud. But when a (very) hostile takeover of the Daily Globe left Spidey with only Madame Web as a possible clue, he paid her a visit personally. Using her psychic abilities, she gave Spider-Man enough clues to lead him to the criminals. Though Spider-Man was still skeptical of her abilities, they were erased when Madame Web called him at his Chelsea Street apartment with knowledge of his identity.

Months later, Black Tom Cassidy sought to add her abilities to his criminal organization, and sent his friend Cain Marko, the Juggernaut, to retrieve her. Madame Web, foreseeing this, called on Spider-Man to help stop the Juggernaut. Despite Spider-Man's efforts, the Juggernaut succeeded in reaching Madame Web. When he lifted her up, he unknowingly removed her from an elaborate life-support system that had been keeping her alive. Finding her thus useless, Juggernaut dropped her and left. Madame Web, barely alive, was taken to the hospital.

While Spider-Man visited her in the hospital, he discovered that the experience had left her with amnesia. ^[1]

Years passed, and Madame Web, seemingly recovered, was contacted by Norman Osborn (1st Green Goblin), to take place in the arcane ritual of the The Gathering of Five. During the ceremony, Madame Web seemingly died, but in truth was granted the power of immortality.

Looking much younger, a rejuvenated Madame Web called upon Jessica Drew and Julia Carpenter, the first two Spider-Women, along with Martha Franklin, who had also taken part in the Gathering of the Five ritual, to aid her in subduing her granddaughter Charlotte Witter, who had become a third Spider-Woman at the hands of Doctor Octopus.

Charlotte was defeated, but later siphoned Madame Web's telepathy, re-aging her in the process. With the help of Spider-Man and Franklin, Madame Web determined how to drain Charlotte's power, leaving Witter unconscious in a dormant state. Madame Web, now youthful again, performed psychic surgery to sever her link to Charlotte and removed Charlotte and Mattie's memories of Spider-Man's identity. Madame Web continued to assist Mattie during the rest of her time as Spider-Woman. The Spider-Women team eventually disbanded. Madame Web has since appeared elderly again, however she presumably has retained her immortality.

Time later, Madame Web was captured by the Kravinoff to help them to defeat Spider-Man and resurrect Kraven. wWth the unvoluntary help of her, Sasha, Ana and Alyosha Kravinoff killed Mattie Frankie (to resurrect Vladimir Kravinoff, the Grim Hunter). Then, the hunters killed Kaine, who was dresed as Spider-Man to save him, and used his blood to bring Kraven back to life, but due the ritual wasn't made with the blood of the true Parker, Kraven wouldn't die exceept if Spider-Man kills him. Angry because this failure, Sasha cut Madame Web's throat. In the last moment of his life, Cassandra transfered her powers to Julia Carpenter (the second Spider-Woman), leaving her the mantle of Madame Web.
