In a world where mutants face escalating hatred, Wolverine reluctantly joins the X-Men after turning down Professor Charles Xavier’s initial offer, drawn in by the team’s desperate fight for coexistence. As the Friends of Humanity, led by the charismatic and ruthless Graydon Creed, spreads anti-mutant propaganda and incites violence across the globe, Bolivar Trask unleashes his advanced Sentinels—massive robotic hunters programmed to capture or eliminate mutants dead or alive. The X-Men, striving to prove they’re heroes rather than threats, battle to protect innocent lives while navigating internal doubts and external prejudice, all while clashing with the Brotherhood of Mutants, whose leader Magneto unleashes brutal counterattacks against the Sentinels and humanity’s oppressors.
Tensions explode as Creed pressures Trask to evolve the Sentinels into even deadlier machines, armed with data from studying the abilities of both the X-Men and the Brotherhood. Wolverine, haunted by his past, becomes the linchpin in the X-Men’s efforts to expose the conspiracy and rally divided mutants, but as alliances fracture and casualties mount, the line between defender and destroyer blurs, forcing a reckoning that could redefine mutantkind’s future—or doom it forever
