Classic X-Men #13

In "Phoenix Unleashed!", Jean Grey's dormant Phoenix powers resurface as Eric (a cunning foe) manipulates Firelord into attacking the X-Men, forcing her to confront the immense energy within. With Lilandra stranded on Earth and captured, Professor Xavier sends the team through a space portal to rescue her, setting the stage for a high-stakes mission where the line between hero and cosmic force begins to blur. Written by Chris Claremont and illustrated by Dave Cockrum and Bob Layton, with vibrant colors by Evelyn Stein and dynamic lettering by Tom Orzechowski and Diana Albers, the issue features a striking cover by Arthur Adams and Al Williamson.
