Classic X-Men #33

In "The Quality of Hatred," Cyclops rallies the X-Men after their devastating first clash with the terrifying Proteus, who now seeks vengeance by hijacking his own father’s body to unleash his full power. Written by Chris Claremont and John Byrne, with art by Byrne and inks by Terry Austin, this 1989 issue deepens the psychological stakes as the team faces a foe whose very essence is twisted hatred. The cover by Steve Lightle captures the chilling intensity of the confrontation.
