Madame Web (Cassandra Webb) is a character appearing in American comic books published by Marvel Comics. She first appeared in The Amazing Spider-Man No. 210, published November 1980, and was created by writer Denny O'Neil and artist John Romita Jr.^[2] She is usually depicted as a supporting character in the Spider-Man comic book series, where she appears as an elderly woman with myasthenia gravis, connected to a life support system resembling a spiderweb.

Madame Web is a clairvoyant and precognitive mutant^[1] who first appears to help Spider-Man find a kidnapping victim. She is not one of the mutants who lost their power during the "Decimation" storyline. In "Grim Hunt", she is attacked by Ana Kravinoff and her mother Sasha, who kills her, but before she dies she is able to pass her powers of precognition as well as her blindness on to Julia Carpenter, who becomes the next Madame Web. Webb is subsequently resurrected by Ben Reilly before succumbing to the Carrion Virus. Webb is the grandmother of the fourth Spider-Woman, Charlotte Witter.

Madame Web has appeared in or served as inspiration for several Spider-Man related media. Rachel Dratch voices "C. Weber", a character loosely based on Madame Web, in Spider-Man: Across the Spider-Verse (2023), while Dakota Johnson portrayed Cassie Webb in the eponymous 2024 film.

Madame Web was created by writer Dennis O'Neil and artist John Romita Jr., and first appeared in The Amazing Spider-Man No. 210 (November 1980).^[3]

Born in Salem, Oregon, Cassandra Webb is a paralyzed, blind, telepathic, clairvoyant, and precognitive mutant^[1] who works as a professional medium. After being stricken with myasthenia gravis, she is connected to a life support system designed by her husband Jonathan Webb, which includes a series of tubes shaped like a spider-web.^[4]

Spider-Man approaches her while looking for kidnapped Daily Globe publisher K.J. Clayton (actually an impersonator fronting for Clayton's circulation manager Rupert Dockery, the kidnapping's mastermind). Madame Web uses her powers to help him locate and rescue both the real and the fake Clayton. She later discloses to him that she already knows his secret identity.^[5]

In the "Nothing Can Stop the Juggernaut!" story arc, she contacts Spider-Man for assistance when Black Tom Cassidy dispatches the Juggernaut to capture her, hoping to exploit her psychic abilities against the X-Men. She nearly dies after Juggernaut separates her from her life-support system. This triggers a fight between Spider-Man and the Juggernaut, who is subsequently trapped in a construction site's wet cement foundation.^[6] The resulting mental trauma, however, means that Madame Web apparently loses her memory of Spider-Man's secret identity.^[7]

Webb is the grandmother of the fourth Spider-Woman, Charlotte Witter. She participates in an arcane ritual known as the "Gathering of the Five" to gain both immortality and eternal youth.^[8] Restored to her physical prime, Webb then serves as a mentor of sorts to the third Spider-Woman, the young Mattie Franklin.^[9]

Madame Web resurfaces, with her psychic powers intact, after Decimation. However, since House of M (in which she appears young), Cassandra seemingly loses her mystical enhancements and reverts to her aged self, though her myasthenia gravis remains gone.^[a]

Madame Web again returns in a back-up feature in The Amazing Spider-Man No. 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 Sasha. The pair incapacitate her and then claim "we now have our eyes".^[10] She is seen still held captive by Ana and her mother, as they inspect their new quarry, Mattie Franklin. While still bound in a chair, she apologizes to a then-unconscious Mattie,^[11] who is later killed by Sasha Kravinoff as part of a sacrificial ritual that revives Grim Hunter.^[12]

At the conclusion of "Grim Hunt", Sasha Kravinoff slashes the throat of Madame Web, believing that Cassandra was deceiving her and knew the outcome of events that transpired. Before dying, Cassandra reveals that she is no longer blind, and passes her psychic powers over to Julia Carpenter.^[13]

During the Dead No More: The Clone Conspiracy storyline, Madame Web is resurrected by Ben Reilly (posing as the Jackal), inserting her soul into a cloned body. Cassandra tips off Prowler about a future bank robbery which he manages to stop. Prowler then goes to get more information on the hacker from Madame Web, who says that she sees buildings filled with agony that cannot escape.^[14] When the villains at New U Technologies are getting out of control, Jackal sends Electro to find Prowler to put them under check again. Electro goes to Madame Web's room and tortures the telepath into giving her Prowler's location with the intent to kill him. Julia Carpenter senses that Madame Web is alive from telepathic feedback resulting from Electro's attack.^[15] Julia infiltrates New U Technologies and uses the opportunity to investigate the near-abandoned facility. During this time, Julia is led to Madame Web who refuses to take medication which could aid her in healing from Electro's attack. Madame Web has seen the future and refuses to be a part of it. Before dying from clone degeneration, Madame Web tells Julia to save Prowler.^[16]

Madame Web is a mutant who possesses several psychic abilities.^[17] She can use telepathy to read the minds of others. She has the ability to see the future.^[18] Madame Web can project an astral form of herself away from her physical body.^[19] She can perform psychic surgery on the minds of others. She is sensitive to psychic energies, allowing her to sense the presence of psionic powers in others, to see the area surrounding her, and events which take place far away from her. Additionally, Madame Web has a gifted intellect.

When dying, she displayed the ability to transfer her mutation to another individual, such as Julia Carpenter.^[20] Madame Web was a victim of myasthenia gravis, a disorder of neuromuscular junction transmission.^[21] As a result, she became entirely dependent on external life support for survival. This is no longer the case as she was cured of the condition some time ago. She is also blind and relies on her powers to compensate.^[22] Madame Web is cybernetically linked to a spider-web-like life-support chair which attends to all of her bodily needs.^[22]
