About this Issue

Ultimate X-Men #17 represents a pivotal mid-series turning point in Peach Momoko's genre-redefining run, escalating the series-long 'rescue Armor' storyline into full-scale confrontation with the Children of the Atom cult and carrying the action directly into the Astral Plane — the book's most psychically charged territory to date. The issue exemplifies what makes this volume historically distinct: a Japanese creator writing and drawing an X-Men book set entirely in Japan, filtered through J-Horror sensibility rather than the traditional superhero idiom, something no prior X-Men series had attempted at this scale within a mainline Marvel imprint. It deepens the emotional arc between Mei Igarashi (Maystorm) and Hisako Ichiki (Armor) that critics and readers identified as the emotional core of the entire 24-issue run. As part of Marvel's second Ultimate Universe initiative — itself a deliberate reimagining of Earth-6160 rather than a reboot of the original 2000s line — this chapter contributed to one of the more creatively autonomous ongoing titles in that line.

History

Peach Momoko conceived and drew the series in Japanese, with Zack Davisson — a scholar of Japanese folklore and co-creator of the Demon Days project with Momoko — serving as English script adaptor throughout the run. The series launched March 6, 2024, as one of the three founding titles of Marvel's revived Ultimate Universe imprint (alongside Ultimate Spider-Man and Ultimate Black Panther), overseen editorially by Jonathan Hickman's broader Earth-6160 framework. Momoko has noted that editor-in-chief C.B. Cebulski and Hickman gave her unusual creative latitude, including permission to introduce wholly original characters, and that the series drew inspiration from anime and manga properties including Puella Magi Madoka Magica and Serial Experiments Lain rather than conventional superhero touchstones. The series concluded with issue #24 in February 2026, having run in near-real time across two years.
