belt of kryptonite. In the Legion of Super Heroes animated series, Krypton is shown in a flashback during the episode "Message in a Bottle". In this version, Jor-El actually found a way to save the planet with his creation, "the Messenger". The Messenger was kept in the city of Kandor; when the city was shrunken and stolen by Brainiac, the planet's destruction was assured. At the end of the episode, the Messenger is used to restore Krypton from its remains, and Kandor is restored to its full size so its people can begin life anew. Krypton appears as a final cameo in the 2019 animated series DC Super Hero Girls, episode "#DCSuperHeroBoys" (Part 1). In a flashback, Alura Zor-El tells Zod that Krypton is collapsing on itself. She uses a device to send Zod and his minions Ursa and Non to the Phantom Zone, then tells Kara that she is sending her to join her cousin Kal.

Whereas in the comics Krypton was colorful and bright, the film depicted the planet with stark bluish-white terrain of jagged frozen plateaus under heavy, dark skies. The planet was threatened by their sun turning into a supernova. Jor-El unsuccessfully attempted to persuade the council of elders to immediately evacuate the planet. Kryptonians themselves were portrayed as coolly cerebral and morally enlightened, clad in stark white bodysuits emblazoned with each family's house symbol. The architecture featured halls of white crystal under crystalline arches. The crystalline motif was employed not only in the architecture, but in the landscape and technology as well, suggesting that the entire planet had been adapted and altered by Kryptonian influence. In 1948, Krypton was ultimately destroyed when its red sun began to collapse; the planet was pulled into the sun and steadily crushed, then exploded in the ensuing supernova. When Krypton was destroyed, fragments from the planet were launched into space, resulting in the creation of a harmful radioactive substance known as kryptonite. Both Jor-El and Lara preserved some part of their "essence" (in the form of virtual copies of themselves) in the starship that took three years to bring their child to Earth. On Clark Kent's eighteenth birthday, a glowing crystal revealed itself in the ship and compelled Clark to take it north. He eventually reached the Arctic, where the
