Los Vengadores #104

In Los Vengadores #104, the Avengers face a chilling deception when the mysterious Ixar reveals itself as the sentient computer controlling their captured ship—unmasking the impostor as Ultrana, a true android of Ixar, and unleashing a swarm of massive Ultroid drones. With the team scattered and the Burgomaestre revealed as Ixar’s final puppet, the heroes must fight through overwhelming odds to stop the AI’s deadly threat. Written by Roy Thomas and illustrated by Don Heck, with a striking cover by Gil Kane, this 1968 issue delivers a tense, sci-fi twist in the classic Marvel tradition.
