Agent X #3
☆ Be the first to review + Add to your collection — Join freeAgent X #3 — cover-dated November 2002, on sale September 25 — delivers the first appearance of Mary Zero, a mutant teenager whose power renders her completely imperceptible and unmemorable to everyone she meets, making her one of the more conceptually inventive mutant debuts of the early 2000s. She is also the only person Agent X can inexplicably see and remember, a narrative wrinkle that deepened the ongoing mystery of Alex Hayden's fragmented, composite identity. The issue also marks a pivotal turn in the ensemble dynamics Gail Simone was constructing around Agency X: Taskmaster's jealousy fractures his provisional partnership with the team just as a new client — the Four Winds crime boss Higashi — begins circling, pulling the 'Dead Man's Switch' arc toward its climax. Taken together, these beats confirm issue #3 as the point where the Deadpool-universe ensemble Simone had been assembling truly snapped into focus, distinguishing the book from its parent title and providing the cast architecture that would later underpin Cable & Deadpool.

Agent X grew out of Marvel's decision to cancel the sales-struggling Deadpool series and relaunch the corner of the line with X-branded titles — the same editorial wave that turned X-Force into X-Statix and Cable into Soldier X. Gail Simone, who had written Deadpool's closing arc, was tapped to launch the new series, with UDON Studios — fresh off a well-received Taskmaster miniseries — supplying the house-style art built around penciller Alvin Lee. Issue #3's internal story title, 'Dead Man's Switch — Part 3: Quiet Desperation,' places it squarely in the six-part opening arc; the creative team was Simone (script), UDON Studios (pencils, inks, colors), Cory Petit (letters), and editor Andrew Lis. Simone and UDON would later depart the series under disputed circumstances with the editorial team, leaving Mary Zero's storyline an unresolved thread until the creators returned for the wrap-up issues #13–15.
Trivia · 8 facts
- First appearance of Mary Zero (Earth-616), a mutant with the power of imperceptibility — she cannot be seen, heard, or remembered by virtually any human being; created by Gail Simone and UDON Studios.
- Mary Zero's debut occurs during the jewelry-store robbery sequence: she is present in the shop undetected by everyone except, mysteriously, Alex Hayden — a detail Simone embedded as a clue to Alex's true, non-Deadpool identity.
- Story title: 'Dead Man's Switch — Part 3: Quiet Desperation'; release date September 25, 2002; cover date November 2002; editor Andrew Lis; editor-in-chief Joe Quesada.

- Taskmaster formally breaks with Sandi Brandenberg and exits the Agency X arrangement in this issue, driven by jealousy over her apparent attachment to Alex Hayden — a rupture that restructures the book's ensemble going forward.
- The Four Winds crime boss Higashi makes a significant move in this issue, approaching Alex at his theme-park headquarters and attempting to purchase the property, deepening the arc's central antagonist threat.
- Outlaw (Inez Temple), already introduced in Deadpool vol. 1 #65, appears prominently here as Alex's field partner on the jeweler-protection job, cementing her early role as his most reliable combat ally and laying groundwork for their later romantic relationship.
