Phantom Zone Criminals

The group of Kryptonian criminals Jor-El banished to the weird “twilight dimension” called the Phantom Zone to serve out their sentences as disembodied wraiths (Act No. 284, Jan 1962: “The Babe of Steel!” and many others). In addition to the criminals, there are also several evil pet cats that live there as well collectively dubbed the Phanty-Cats (SB No. 136, Mar 1966: "Decoy of the Doom Statues!"). Same of the names of Phantom Zone Criminals are Faora Hu-Ul, Jax-Ur, Kru-El, Nam-Ek, Quex-Ul, Ral-En, Ras-Krom, Professor Vakox, and General Zod.
