Madame Web was a clairvoyant and precognitive mutant who first showed up to help Spider-Man find a kidnap victim. Madame Web was not one of the mutants that lost their power during the "Decimation" storyline. She was attacked by Sarah and Ana Kravinoff, who killed her, but not before she was able to pass her powers of precognition, as well as her blindness, on to Julia Carpenter, who became the next Madame Web. Webb is the grandmother of the fourth Spider-Woman, Charlotte Witter.
