Madame Web debuted in November 1980 in Amazing Spider-Man #210, created by Denny O'Neil and John Romita Jr. at Marvel Comics. A blind psychic linked to the Web of Life and Destiny, Cassandra Webb spent decades as an oracle to Spider-Man before becoming a pivotal figure in the Spider-Society and the Web Warriors during the Spider-Verse crossover in 2014. This guide traces her debut, her full biography, the series timeline, the key issues to know, and the major arcs worth collecting.
Madame Web was never a front-and-center character, and that is exactly what makes her a sought-after target for savvy collectors. Introduced at the tail end of Marvel's Bronze Age, she remained confined to a narrative support role for nearly thirty years — a blind old woman in her web-chair, plugged into invisible threads only Peter Parker can glimpse. The release of Sony's Madame Web film in February 2024, despite its mixed critical reception, reignited market interest in Amazing Spider-Man #210, whose value posted a clear upward move between 2022 and 2024 according to GoCollect sales and eBay tracking.
This article traces the character's debut in 1980, her in-universe biography under both identities — Cassandra Webb and Julia Carpenter — the timeline of solo series and miniseries devoted to her, the ten key issues every Spider-Man collector should know, and the major arcs (notably Dan Slott's run on Spider-Verse). For the issue-by-issue breakdown with value ranges, the article Madame Web key issues rounds out this overview.
Madame Web biography
Madame Web is a Marvel Comics character created by Denny O'Neil and John Romita Jr. Her first appearance comes in Amazing Spider-Man #210 (November 1980). Originally conceived as a narrative device to flesh out Spider-Man's mystical mythology, she became, over the decades, one of the central pieces of the Web of Life and Destiny concept — a metaphysical web connecting every spider incarnation across the Marvel multiverse.

Character origins
In the late 1970s, Denny O'Neil took over the reins of Amazing Spider-Man and looked to introduce supporting figures capable of enriching the myth without pushing Peter Parker from the center of the story. Madame Web was born from that editorial need: a blind, paralyzed psychic, dependent on a web-chair that keeps her frail body alive. In-universe, Cassandra Webb was born with myasthenia gravis and blindness. She develops extensive psychic abilities early on, which lead her to serve as an oracle for various incarnations of Spider-Man. Marvel continuity kills her off during the Grim Hunt crossover (2010), in which Kraven the Hunter stalks the heroes tied to the spider identity. Before she passes, she transfers her powers to Julia Carpenter, the former Spider-Woman, who takes up the Madame Web identity and the journey through the Web of Life all the way to the events of Spider-Verse.
Powers and abilities
- Clairvoyance and precognition: visions of the near and distant future, often fragmentary
- Telepathy: mind-reading and mental communication, sometimes over great distances
- Connection to the Web of Life and Destiny: perception of every spider timeline
- Astral projection: the ability to manifest outside her physical body
- Psychic guidance: relaying critical information to the Spider-Totems of the multiverse
Costume and visual identity
John Romita Jr.'s original design instantly establishes an unusual visual identity: a deep-red gown, opaque glasses compensating for her blindness, and above all the mechanical web-chair that serves as both life support and symbol. When Julia Carpenter takes over the role after Grim Hunt, the costume shifts toward a more active silhouette: a dark bodysuit, a band covering her now-white eyes, and the partial abandonment of the chair. This is the version found mainly in Spider-Verse and Dan Slott's later arcs.
Madame Web series timeline
Madame Web never had a long-running, ongoing solo series. Her appearances span four decades across Spider-Man comics, miniseries, and major crossovers. Here are the main editorial milestones.
Amazing Spider-Man appearances (1980–2010)
From Denny O'Neil to Roger Stern and then J.M. DeMatteis, Madame Web moves through thirty years of Spider-Man continuity as a recurring figure. She guides Peter Parker at pivotal moments (Hobgoblin, Inferno, the periphery of the Clone Saga) and racks up appearances without ever crossing the threshold into a lead role.
The Amazing Spider-Man: Grim Hunt
Written by Joe Kelly and drawn by Michael Lark, this crossover marks the death of the original Cassandra Webb during the hunt led by the Kravinoff family. Before she dies, she passes her powers to Julia Carpenter, opening the character's second era. A foundational arc for the post-2010 mythology.
Spider-Verse (Dan Slott)
Dan Slott places Madame Web (Julia Carpenter) at the heart of the resistance against the Inheritors. She links the Spider-Totems of the multiverse through the Web of Life and Destiny and founds the Spider-Society. This is the arc that retroactively turns the character into the keystone of Marvel's spider multiverse.
Madame Web (2024 miniseries)
A miniseries launched by Marvel alongside the Sony film's release, written by Steve Foxe. It recenters the character on Cassandra Webb in an origin-story rereading. Variant covers were in high demand at launch and are now settling into market stabilization.
Top 10 Madame Web key issues
A selection of the ten issues every completist Spider-Man collector should identify. The value ranges given remain approximate — for up-to-date detail, the article Madame Web key issues keeps a record of recent sales.
Amazing Spider-Man #210
The founding issue. First appearance of Cassandra Webb by O'Neil and Romita Jr. The value in CGC 9.6/9.8 grade saw a strong surge between 2022 and early 2024, driven by the announcement and then the release of the Sony film. Stabilization has been observed since mid-2024. The cornerstone of any Madame Web collection.
Amazing Spider-Man #213
The character's quick second appearance, right on the heels of #210. Often overlooked by the market, this issue remains accessible in high grades and makes a reasonable entry point for anyone who can't aim for #210 in CGC 9.8.
Marvel Team-Up #132
A substantial appearance in the Team-Up series. Here the character takes a more active role than in her early outings. An interesting issue for Spider-Man completists who cover the related series.
Web of Spider-Man #5
An emblematic issue from the 1980s phase where Madame Web cements her status as a recurring mystic mentor in the Spider-Man galaxy. Sought after by collectors of late Bronze Age and early Copper Age Spider-Man runs.
Amazing Spider-Man #637
The final chapter of Grim Hunt, where Cassandra Webb dies and passes her powers to Julia Carpenter. A major mythological turning point: this issue cements the transition between the two Madame Webs and sets up everything that follows in Spider-Verse.
Marvel Team-Up #146
One of Madame Web's later appearances in Marvel Team-Up, shortly before the series ended. An often-neglected issue that rounds out the character's 1980s phase nicely for collectors looking to reconstruct the complete timeline.
The Amazing Spider-Man #634
The first chapter of the Grim Hunt crossover. Madame Web plays a pivotal role right from the opening. An interesting issue as a bookend to #637 for those who collect complete arcs rather than isolated issues.
Amazing Spider-Man #9 (vol. 3)
The opening issue of Dan Slott's Spider-Verse crossover. Madame Web (Julia Carpenter) plays a structural role here: she assembles the Spider-Totems through the Web of Life and Destiny. A sought-after issue since the spider multiverse took off on screen.
Madame Web #1 (2024 mini)
The first issue of the 2024 solo miniseries, released to accompany the Sony film. Variant covers (notably the 1:25 and 1:50 ratios) were sought after at launch and are now correcting. The Cover A holds steady — one to watch.
Spider-Woman #1 (1978)
For collectors covering the second Madame Web: Julia Carpenter first wore the Spider-Woman costume (her original appearance is in Marvel Super Heroes Secret Wars #6, 1984). Spider-Woman #1 remains an essential adjacent issue for contextualizing her pre-Madame Web arc.
Major arcs and cult runs
Three arcs structure the Madame Web legacy. Grim Hunt (2010), by Joe Kelly and Michael Lark, seals Cassandra Webb's death and installs Julia Carpenter in the role — a pivotal moment every serious reader should take in before tackling Spider-Verse. Spider-Verse (2014–2015), by Dan Slott, Olivier Coipel, and Giuseppe Camuncoli, makes Madame Web the architect of the multiverse battle against the Inheritors. It's the arc that retroactively turns the character into the keystone of all recent spider mythology, and its influence carries on into Spider-Geddon (2018) and End of the Spider-Verse (2022–2023). Finally, the Madame Web miniseries (2024) by Steve Foxe, conceived as a marketing tie-in to the Sony film, offers an origin-story rereading more accessible to new readers — useful as an entry point, but without the canonical weight of the two preceding arcs.
Adaptations and cultural impact
The Madame Web film adaptation released by Sony in February 2024, with Dakota Johnson in the title role, met with a very unfavorable critical reception and disappointing box-office results. But its effect on the collector market was far from nil: Amazing Spider-Man #210 saw its value climb from the film's official announcement in 2022, peaking in early 2024 before stabilizing. The phenomenon echoes the effect Marvel Studios announcements have on long-dormant issues — see also the history of Amazing Spider-Man for the broader context. Beyond the film, the character benefits from the overall trajectory of Spider-Verse on screen (animated films, Sony projects), which sustains baseline demand for issues tied to the Web of Life and Destiny.
