X-Factor #10
X-Factor #10 is the emotional and structural pivot of the Mutant Massacre crossover — the first multi-title X-Men event in Marvel history — delivering the issue's signature gut-punch: the Marauders pinning Angel to the tunnel wall by his wings, an injury that would set in motion Warren Worthington III's transformation into the Horseman Death and eventually into Archangel. The issue also contains the first on-panel recruitment of a Horseman of Apocalypse, as the ancient mutant swoops in during the slaughter to claim the Morlock Plague as his Pestilence, planting the seed for one of the X-line's defining villain mythologies. As the debut issue of Walt Simonson on pencils working alongside his wife Louise Simonson as writer, it marks the beginning of the creative partnership that would define the series for the next three years and produce some of the most consequential X-Men storytelling of the late 1980s.

Louise Simonson had taken over X-Factor's writing duties from the book's original writer Bob Layton with issue #6, and it was in that issue that she introduced Apocalypse to the Marvel Universe. With issue #10, her husband Walt Simonson joined as regular penciler — a collaboration that, according to both creators, was treated professionally rather than domestically, with Walt not co-plotting the scripts. The issue landed squarely in the middle of the Mutant Massacre crossover, which Louise Simonson herself had helped shepherd from a single-title concept into a sprawling, six-series event spanning thirteen issues; editor Bob Harras oversaw the issue under editor-in-chief Jim Shooter. The November 1986 cover date placed it among a slate of Marvel titles bearing a special decorative border celebrating the publisher's 25th anniversary year, marking the quarter-century since Fantastic Four #1.
Trivia · 8 facts
- Title: 'Falling Angel' — written by Louise Simonson, penciled by Walt Simonson (his first issue on the series), inked by Bob Wiacek, colored by Petra Scotese, lettered by Joe Rosen, edited by Bob Harras.
- First appearance of Marauder Blockbuster, who makes his debut attacking Morlocks in the tunnel sequence and breaking Angel's wings before Harpoon delivers the killing blow.
- First appearance (and death in the same issue) of Marauder Prism, whose crystalline body is shattered by Marvel Girl's telekinesis after he reflects Cyclops's optic blast back at him — making him simultaneously a debut and a casualty.
- First and only appearance of Zeek, a Morlock who dies during the massacre; his mutant abilities are never established on-panel.
- Second overall appearance of Apocalypse (En Sabah Nur), who intervenes during the massacre to rescue the Morlock Plague from Harpoon and Sabretooth, declaring her his first Horseman — Pestilence — in the earliest on-panel recruitment scene for the Horsemen of Apocalypse concept.
- Angel (Warren Worthington III) is pinned to the tunnel wall through his wings by Harpoon's energy weapons, the injury that begins his long physical and psychological decline toward his eventual rebirth as the metal-winged Archangel (a transformation completed in later issues).
- The issue is a core chapter in the Mutant Massacre crossover — the first coordinated multi-title X-Men event — which ran across Uncanny X-Men, X-Factor, New Mutants, Thor, Power Pack, and Daredevil; this issue continues directly from X-Factor #9 and leads into Power Pack #27.
- The cover carries Marvel's 25th Anniversary decorative border, applied to select November 1986 releases commemorating the 25 years since Fantastic Four #1 (November 1961).
