Spoilers: In Estrella, South America, La Diabla—assisted by “Colossus” and the Brute That Walks—successfully defeats the entire X-Force roster. A mysterious figure, revealed to be La Diabla’s superior, communicates with her, hinting that she’s following someone else’s orders. Using her alchemy, La Diabla transforms the Brute back into Dr. Avery.
As Forge, Betsy, and Rachel lie unconscious, “Colossus” suggests killing Rachel first—only for John Wraith, a.k.a. Kestrel, to teleport in and whisk Rachel to safety. Suddenly, Sage reemerges, flanked by a squad of X-Sentinels resembling Havok, Cyclops, Angel, and Beast. While “Angel” rescues Betsy, the other Sentinels engage the villains—though “Havok,” “Cyclops,” and “Beast” are quickly disabled.
The surviving X-Force members regroup near Sage’s VTOL, but the X-Sentinel “Angel” is abruptly destroyed by the Brute That Walks. La Diabla, Brute, and “Colossus” immediately resume combat against the X-Force.
Meanwhile, the mysterious villain contacts La Diabla once more, stating he has plans for Forge and ordering her to open a portal. The mastermind is revealed: Moses Magnum, the architect behind the fracture network. Forge analyzes the Analog and understands Magnum’s goal—and to everyone’s shock, he defects, choosing to join Magnum.
Before leaving, Forge removes his anti-telepathy headband, allowing Rachel and Betsy to read his mind and uncover the truth.
Magnum, La Diabla, Brute, “Colossus,” and now Forge travel to Subterranea, an ancient kingdom beneath the Earth once home to the Deviants—specifically, the city of Dys. There, Moses Magnum outlines his twisted philosophy: both humans and mutants have failed—humans in eradicating mutants, and mutants in protecting themselves. His plan is to tear a breach in the continuum and unleash otherworldly monsters, forcing humanity and mutantkind to unite as one race. For that, he needs Forge to finish building the Resonator, a device powered by Magnum’s own energy that would keep the portal open permanently.
X-Force arrives in Dys aboard the Blackbird. Tank removes his mask and finally reveals his true identity: the real Piotr Rasputin, Colossus.
The imposter “Colossus” exposes herself as Zanda, former ruler of the African nation of Narobia. She shapeshifts into a giant lizard and battles the real Colossus one-on-one.
Rachel confronts the Brute That Walks. She reaches out to Dr. Avery telepathically and, while she can’t undo La Diabla’s mental bindings, she offers him clarity—visualizing Avery as greater than the beast. This shift gives him the strength to master his rage and regain control of his form.
Elsewhere, Betsy Braddock faces La Diabla head-on. With her psychic butterfly sigil blazing, Betsy dismisses La Diabla’s tricks and schemes as hollow. She declares that she has always known she was eldritch. Brandishing her golden Starlight Sword, Betsy cuts through La Diabla’s alchemy with ease—asserting that she is the magic.
At that moment, Wraith teleports in with Sage. Sage reveals she finally understands Forge’s true intentions—that sealing the fractures, removing the anti-telepathy headband, and leaving the Analog behind were all moves to guide X-Force to this very point.
Forge asks if Sage brought what he requested. She confirms—and throws Surge’s gauntlets into the Resonator, overloading and destroying the machine permanently. Solution locked.
Moses Magnum, La Diabla, and Zanda teleport away in defeat. Forge explains that he kept everyone in the dark because X-Force was his machine, built to operate according to his design.
In the final moment, Surge resurrects herself in the form of coherent plasmatic energy, shocking her teammates. Forge swears he didn’t know this would happen. Sage, looking weary, tells him that after everything he’s done—X-Force is over.
“For so long, my life has been out of control. Chaos and serendipity, wrapped in insanity. I have suffered, I have lost. Not just my life, but my very soul, my self. But no more. Now I know who I am.” – Elizabeth ‘Betsy’ Braddock, daughter of Otherworld, mutant, telepath, telekinetic, defender of the realm and, above all, X-Man.
