Superman: Unbound

In the vast universe of DC Comics, few villains pose as colossal a threat as Brainiac—the cybernetic being whose ambition and power have made even the most powerful heroes tremble. In this new story, Superman and Supergirl are forced to join forces to confront the fearsome enemy who claims to possess “the knowledge and strength of 10,000 worlds.”

Brainiac is not merely a machine of destruction; he is a highly evolved artificial intelligence that travels from planet to planet, collecting information and technology, then destroying the worlds so that no one else can match his power. His obsession with perfection and absolute control has turned him into an intergalactic threat—and now, his sights are set on Earth.

When Superman detects the arrival of an alien ship of colossal proportions, he knows something is terribly wrong. Upon investigating, he discovers it is Brainiac, who has come to add the knowledge of Earth to his collection. But this time, the Man of Steel is not alone. Kara Zor-El, also known as Supergirl, joins the fight. With her own Kryptonian heritage and equally formidable strength, Kara becomes a key figure in the battle for the fate of humanity.
