In some versions of the story, additional survivors were later discovered, such as Krypto the Superdog, Supergirl, her parents (kept alive in the "Survival Zone", a similar parallel "dimension" to the Phantom Zone), the criminal inhabitants of the Phantom Zone, Dev-Em, Beppo the Super-Monkey, the residents of the bottled city of Kandor, and the real parents of both Superman and Supergirl. Kandor, the first capital of Krypton, is miniaturized by Brainiac, but it is eventually recovered by Superman and subsequently housed in the Fortress of Solitude for safekeeping. Soon afterward, Kryptonopolis becomes the second capital of Krypton.
