X-Men #3

In "Potjera," Scott's grief over Thunderbird's death spirals into chaos when it awakens an alien demon targeting the X-Men. With Moira now at the mansion and Lang pushing Project Armageddon with ruthless intent, tensions rise as old wounds and hidden agendas threaten to tear the team apart. Written by Chris Claremont and Bill Mantlo, with dynamic art by Dave Cockrum and Sam Grainger, this 1997 issue delivers a gripping blend of emotional stakes and high-stakes action. The cover, a collaborative effort by Sal Buscema, John Romita, and Dave Cockrum, captures the turmoil in bold, expressive lines.
