Ultimate X-Men #13
☆ Be the first to review + Add to your collection — Join freeUltimate X-Men #13 marks the formal opening of the series' second year — the structural hinge point where Peach Momoko's slow-burn, horror-inflected mutant fable pivots from world-building to full-scale psychic warfare. The issue delivers the team's first coordinated group battle, a meaningful narrative first for a book that had previously prioritised slice-of-life dread over superhero action, and it deepens the Shadow King arc by corrupting Hisako into 'Dark Armor,' dramatising the series' central theme — Hisako's inner darkness becoming a literal weapon against her friends. As the opening chapter of the 'Realm of the Mind' storyline (collected in Vol. 3), it inaugurates a sustained Astral Plane narrative that critics have cited as among the most visually and tonally distinctive sustained sequences in Marvel's current publishing line.

The series is written and illustrated by Japanese artist Peach Momoko, with English script adaptation by Zack Davisson, both veterans of the earlier Demon Days collaboration for Marvel. Momoko has stated that editor-in-chief C.B. Cebulski and Jonathan Hickman specifically sought her out because they wanted something 'completely new and different,' and she has acknowledged drawing little from classic X-Men source material, grounding the book instead in Japanese horror manga and J-horror aesthetics. Issue #13 released on March 19, 2025, accompanied by a special Benjamin Su 'One Year In' foil variant and additional incentive covers by Iban Coello and Martin Simmonds, recognising the series' first anniversary alongside parallel anniversary issues across the Ultimate Universe line.
Trivia · 8 facts
- Released March 19, 2025 (cover-dated May 2025); written and illustrated by Peach Momoko, script adaptation by Zack Davisson, lettering by Travis Lanham.
- First issue of the series' second year and the opening chapter of the 'Realm of the Mind' arc, later collected in Ultimate X-Men by Peach Momoko Vol. 3 (ISBN 978-1302958343), which collects issues #13–18.
- The issue is the first in the series to depict the team fighting as a coordinated unit — a deliberate structural departure from the slice-of-life and horror-mystery pacing that defined the book's first twelve issues.
- Shadow King (in his Ultimate Universe incarnation as Shinobu Kageyama) corrupts Hisako Ichiki/Armor into 'Dark Armor,' using her as a weapon against her teammates — the arc's central dramatic escalation.
- Kanon Sainouchi (Ultimate Psylocke analogue) defeats Dark Armor, marking her first showcase as the team's most combat-capable member and the most direct parallel to a classic X-Men power-set in the series.
- The issue shipped with three variant covers: a 1:25 incentive by Iban Coello, a 'One Year In' foil variant by Benjamin Su (shared across the anniversary issues of the Ultimate Universe line), and a standard variant by Martin Simmonds.
- Peach Momoko's art in this issue employs her signature watercolour style to render action sequences, a creative choice reviewers noted as unconventional for a superhero battle issue but effective in sustaining the series' dreamlike, eerie tone.
- The series deliberately omits classic X-Men touchstones (X-Mansion, Sentinels, Professor X) in favour of a Japan-set story about teenage mutant outcasts, with character analogues (e.g. Natsu Tsukishima as Cyclops, Mei Igarashi as Storm/Maystorm) replacing rather than reimagining the traditional roster.
