corrupts Val-El's image, brings the ship and teleports with Seg's and Nyssa's son, Jor-El, leaving from the Krypton somewhere in space. Film Original film series (1978-2006) In Superman and its sequels (except for Superman III, in which it did not appear), the Fortress is created by a crystal that Jor-El enclosed in Kal-El's spaceship. The crystal leads teenage Clark Kent to an ice field where it is "planted" by Clark, after which it melts into the ice and grows into a huge crystalline building, similar to the crystalline architecture shown on Krypton at the beginning of the film. This fortress was also used to start Kal-El's 12-year training to become Superman. This Fortress contains numerous "memory crystals" that can be used to access Jor-El's artificial intelligence and hologram, interactive holographic recordings of Lara, and other Kryptonians, and a chamber that uses red sun radiation to strip Kryptonians of their super powers. In Richard Donner's cut of Superman II, the Fortress is destroyed by Superman as its existence was revealed to Lex Luthor and his henchwoman, Eve Teschmacher. However, Superman then turns back time (à la 1978's Superman), so technically the Fortress is completely undamaged, while Zod, Ursa and Non are returned to the Phantom Zone. In Superman Returns, the Fortress follows the same formula as the earlier movies, but goes into more detail about the crystal origins of the Fortress and Kryptonian architecture. Lex Luthor attempts to use memory crystals he stole from it to create a new land mass in place of America. An observation is made (following Superman II) that he acts as though he has been there before. The crystals that power the Fortress were lost when Lex Luthor's assistant dropped them out the escaping helicopter into the ocean below. The tie-in book, Superman Returns: The Visual Guide lists the Fortress as sitting on "Fletcher's Abyssal Plane". DC Extended Universe The 2013 film Man of Steel depicts the Fortress of Solitude as a Kryptonian Scout Ship that crashed on Earth thousands of years ago (revealed in the Man of Steel comic to be because of a fight between Kara Zor-El and Dev-Em), with highly advanced alien technology. One of these aboard is a standard Genesis Chamber that can be used to repopulate Kryptonians for outposts and several smaller Kryptonian robots, one that almost killed Lois Lane but was saved by Kal-El / Clark Kent.
