Here are seven unforgettable story arcs featuring AI characters in comic books that have captivated readers and left a lasting impact on the genre.

1. Ultron’s Reign in “The Avengers: Ultron Unlimited” (1999)

Ultron, one of Marvel’s most iconic AI villains, takes center stage in The Avengers: Ultron Unlimited, written by Kurt Busiek and illustrated by George Pérez. In this storyline, Ultron returns more powerful than ever, launching a devastating attack on the fictional nation of Slorenia. Ultron’s ultimate goal is to create a new world populated entirely by his robotic creations, eradicating humanity in the process.

In this arc, Brainiac seeks to expand his collection of cities by capturing and shrinking Metropolis. The story explores Brainiac’s obsession with knowledge and his cold, calculating nature, as well as Superman’s determination to protect Earth from this remorseless adversary.

Why It’s Unforgettable:
