Years after Superman Returns, the world questions its need for heroes. When a mysterious crystalline signal revives the artificial intelligence Brainiac, he creates a perfect mirror copy of Superman — El-Kal, designed to replace humanity’s protector with a conqueror.
Brainiac’s warships invade Earth, converting cities into data constructs. Superman faces his clone in a battle stretching from Metropolis to orbit. Only by embracing both his Kryptonian and human identities can he outwit Brainiac and save his son, Jason.
