Essential Classic X-Men #2

In "The Power and the Pendant!", the X-Men take a rare weekend break, only to find themselves caught in a high-stakes crisis when former Stark employee Ralph Roberts dons the Cobalt Man suit and goes rogue. With Cyke, Angel, and Jean in the mix, the team must stop Ralph before his unstable armor triggers a catastrophic meltdown—before it’s too late. Written by Roy Thomas and illustrated by Werner Roth, with inks by John Tartaglione and letters by Sam Rosen, this classic tale features a dynamic cover by Gil Kane, John Romita, and Sol Brodsky.
