War

A powerful mutant recruited by the immortal Apocalypse to serve as one of his Four Horsemen, War was transformed and empowered to embody conflict and destruction as part of Apocalypse's plan to test — and ultimately cull — humanity.

Riding into Marvel's mutant mythology in 1987, War burst onto the scene in X-Factor #15 — a Louise and Walter Simonson creation who arrived at precisely the right moment, when the X-books were crackling with some of their most ambitious, high-stakes storytelling. A figure of genuine collector significance with two key-issue appearances to their name, War has endured across an impressive 34-year span, turning up throughout X-Factor, The Uncanny X-Men, and beyond. With team affiliations spanning X-Factor, X-Force, and the X-Men themselves, and a rogues' gallery of co-stars that includes Jean Grey, Beast, and Warren Worthington III, War occupies a fascinating corner of the Marvel Universe — one well worth exploring for any serious fan of the Copper Age mutant era.
