About this Issue

Released on May 28, 2025, Giant-Size X-Men #1 serves as the opening chapter of a five-part anniversary event explicitly timed to mark fifty years since the 1975 original that reshaped the X-Men franchise — making it Marvel's most structurally self-aware X-Men anniversary project since the Krakoan era one-shots of 2020. The issue carries genuine narrative weight as the first story to dramatize Kamala Khan's latent mutant powers awakening within the context of classic X-Men history, retroactively weaving Ms. Marvel into the founding mythology of the 'Second Genesis' era. Its backup feature, 'Revelation: Superior,' delivers the first appearance of Justina LaGuardia, a Roman mutant whose power of absolute superiority over anyone near her — including Charles Xavier himself — positions her as one of the most formidable new characters introduced in the X-books in years. Together, the two stories reframe both a beloved character's identity and fifty years of established continuity at once, a genuinely ambitious editorial mandate.

History

The 2025 Giant-Size X-Men event originated from X-line editor Tom Brevoort's announcement, made in late 2024, that a 50th-anniversary celebration of the original 1975 issue was coming 'but not exactly in the way you're imagining.' Writers Collin Kelly and Jackson Lanzing — already handling NYX at Marvel — were assigned the five-issue spine of the project, with Adam Kubert (himself a storied X-Men artist) penciling the opening and closing chapters, and C.F. Villa and Francesco Manna handling the middle installments. The creative structure deliberately parallels the 1975 original's own dual-narrative DNA: just as Len Wein and Dave Cockrum's book contained both a lead adventure and archival reprints, the 2025 version pairs a main time-travel story by Kelly and Lanzing with standalone 'Revelations' backup stories by writers including Al Ewing, Sara Pichelli, Steve Foxe, Jeph Loeb, Saladin Ahmed, and Jed MacKay, each seeding future X-Men storylines. A prelude issue distributed free on May 3, 2025 — Free Comic Book Day 2025: Fantastic Four/Giant-Size X-Men #1 — primed readers for the event before the main series launched.

Trivia · 8 facts

Published May 28, 2025 by Marvel Comics; first of five oversized one-shots running through August 2025, collectively titled the Giant-Size X-Men: Second Genesis Revisited event.
Main story ('The Mutant That Walks Like a Man') written by Jackson Lanzing and Collin Kelly, with art by Adam Kubert and colors by Laura Martin; lettered by Clayton Cowles; edited by Tom Brevoort.
Backup story ('Revelation: Superior') written by Al Ewing with art by Sara Pichelli and colors by Federico Blee — the first appearance of Justina LaGuardia (codename: Superior), an Italian mutant detective whose power allows her to instantly surpass the abilities of anyone near her, including outclassing Professor X's telepathy.
Justina LaGuardia's debut is set in the same 1975 era as the original 'Second Genesis,' framed as a hidden moment Xavier experienced while recruiting the new X-Men — she refuses his invitation and telepathically wipes his memory of their encounter.
The main story features Kamala Khan (Ms. Marvel) pulled back in time by Legion to witness the X-Men's first encounter with the sentient island Krakoa, the same adventure depicted in the original 1975 Giant-Size X-Men #1; she joins the Second Genesis rescue team alongside Cyclops, Wolverine, Colossus, Nightcrawler, Thunderbird, Storm, and Banshee.
The issue marks the in-story moment when Kamala's latent mutant powers begin to surface, depicted as a golden hard-light aura — powers later confirmed to be the generation of hard-light constructs, paralleling her MCU power set and distinct from her Inhuman embiggening ability.
Adam Kubert's cover art is a deliberate visual homage to Dave Cockrum's original 1975 Giant-Size X-Men #1 cover, with Kamala Khan inserted into the roster alongside the classic Second Genesis team.
The full event was subsequently collected in the trade paperback Giant-Size X-Men: Second Genesis Revisited, collecting all five one-shots plus material from the FCBD prelude.
