Marvel Masterworks: The X-Men #4

In "Along Came a Spider...", the X-Men are summoned by Banshee to confront a mysterious spider-like creature terrorizing the area. When the young mutants encounter Spider-Man, they mistake him for the villain, sparking a tense and unexpected clash.

In "Now Strikes...the Sub-Human!", the last of a buried civilization, Gor-Tok, rises from the depths to confront the human world he blames for his people’s extinction. With a fury born of loss, he targets those responsible, turning the underground world into a battleground of vengeance and fear.

In "The Living Diamond!", Jack Winters takes a desperate gamble, infiltrating the Cyclotron and exposing himself to radiation in a bid to transform entirely into diamond—succeeding in becoming a living, crystalline being with terrifying potential.

In "If I Should Die...!", Professor X faces off against the vengeful Grotesk, who seeks to unleash the oscillotron and bring humanity to its knees. As the device activates and the X-Men rush in to stop it, the battle escalates—until a devastating twist leaves Professor X seemingly dead in the aftermath.

In "The End...or the Beginning?", the aftermath of a devastating battle sees the Living Diamond reduced to atoms, leaving Professor X and Scott Summers to face the uncertain future. With the dust settling, Professor X turns to Scott with a pivotal request—ask him to be the first to join a new mission dedicated to building trust between humans and mutants.
