WARNING: MAJOR SPOILERS AHEAD
Chapter 1: Echoes of Krypton
Years ago, on the distant planet of Krypton, its inhabitants went to war against the Shi'ar Empire that entered their galaxy and invaded their planet. Within six years, the Kryptonians repelled the Shi'ar through their powerful technology thanks to the efforts of General Dru-Zod, the head of the Kryptonian Defense Force, who broke the siege aided by the new weaponry developed by Krypton's most brilliant scientist, Jor-El, Zod's longtime friend. With the Shi'ar defeated, the Shi'ar Emperor Kral'Nor was overthrown and exiled by a group of Shi'ar that opposed the war and the expansion. The New Shi'ar Empire quickly negotiated for peace and ending the war.
However, Zod is later accused for war crimes of destroying Shi'ar warships that were about to surrender. Judged by Krypton's Council of Twelve, of which Jor-El is a part of, Zod justified that his actions were necessary to defending their planet through absolute force and doesn't show any remorse for his actions. The Council sentenced Zod to be exiled into the Phantom Zone.
Following the trial, Jor-El present his findings concerning the possibility of Krypton's imminent destruction. However, the Council ignores Jor-El's warnings after Brainiac, Krypton's omniscient central computer created by Jor-El, dismisses Jor-El's findings and explains that Krypton is only undergoing a planetary shift. But Jor-El soon learns directly from Brainiac that it lied so that it could secretly download himself into a satellite and escape the planet's destruction, rather than be ordered to waste time preparing an evacuation plan. According to its programming, the survival of Krypton's knowledge is more important than that of its people. Jor-El, however, stops the download and takes all the knowledge Brainiac had before shutting the A.I. to prevent its escape. But as Jor-El leave, Brainiac had already issued an upload command.
Jor-El returns to his home and warns his wife Lara that Krypton will explode in only a matter of hours. Jor-El quickly makes preparations for his back-up plan: to save his baby son, Kal-El, by sending him to Earth in a small one-person spaceship. With little choice left, Kal-El's ship is launch moments away as Krypton explodes.
On Earth, at the Xavier Institute, Professor Charles Xavier and Erik Lensherr argues about humanity's acceptance of mutants; in which the former believes in coexistence between humans and mutants while the latter strongly believes that humanity will fear and loathe mutants and, inevitably, wage war on mutantkind; in which Lensherr intends to fight it. As Xavier tries to reason with his friend, he suddenly senses Krypton's destruction and its people's death cries. Although Xavier is disturbed, he couldn't understand what he felt just as Lensherr ends their discussion and leaves.
Ten years later Kal-El's spaceship reaches Earth's solar system in the midst of a meteor shower that was left over from Krypton's destruction.
