The Phantom Zone is a prison-like parallel dimension appearing in American comic books published by DC Comics. It is mainly associated with stories featuring Superman. It first appeared in Adventure Comics #283 (April 1961), and was created by Robert Bernstein and George Papp.^[1] It was frequently used in the Superman comics before the continuity was rebooted in the 1980s, after Crisis on Infinite Earths, and has appeared occasionally since.

The Phantom Zone was a "pocket universe" discovered by Jor-El that existed outside the space-time continuum; it was used on the planet Krypton as a humane method of imprisoning criminals.^[2] Kryptonians had abolished the death penalty in the long distant past. In more recent history, criminals were punished by being sealed into capsules and rocketed into orbit in suspended animation with crystals attached to their foreheads to slowly erase their criminal tendencies; Klax-Ar was one criminal who received this punishment but escaped. Gra-Mo was the last to suffer the punishment, for it was then abolished in favor of the Zone.

The inmates of the Phantom Zone reside in a ghost-like state of existence from which they can observe, but cannot interact with, the regular universe.^[3] Inmates do not age or require sustenance in the Phantom Zone; furthermore, they are telepathic and mutually insubstantial. As such, they were able to survive the destruction of Krypton and focus their attention on Earth, as most of the surviving Kryptonians now reside there.^[4] Most have a particular grudge against Superman because his father created the method of their damnation, and was often the prosecutor at their trials. When they manage to escape, they usually engage in random destruction, particularly easy for them since, on Earth, each acquires the same powers as Superman. Nevertheless, Superman periodically released Phantom Zone prisoners whose original sentences had been completed, and most of these went to live in the bottle city of Kandor.

The sole inmate of the Phantom Zone who was not placed there as punishment for a crime is Mon-El, a Daxamite who fell victim to lead poisoning. Superboy was forced to cast him into the Phantom Zone to keep him alive, where he remained for nearly a thousand Earth years until the time of the Legion of Super-Heroes when Brainiac 5 created a medication that allowed him to leave safely.

Green Lantern Guy Gardner once experienced an extended and tortuous stay after an explosion of a Green Lantern power battery sent him there, until rescued by Superman and Green Lantern Hal Jordan, who had believed him to be dead all that time.

Phantom Girl can enter or leave the Phantom Zone as she pleases, and once did so to interrogate the prisoners about Jor-El.^[5]

Superman develops communications equipment for the Phantom Zone, like the Zone-o-Phone, and refinements to the projector. In addition, the city of Kandor uses the Phantom Zone regularly, with parole hearings sometimes chaired by Superman. However, since the departure of Kandor, that is, outside of Mon-El, most of the inhabitants were confined to lifers and generally not inclined to making conversation with their jailer. As for Superman himself, as much as he appreciates how the Zone is necessary to contain its Kryptonian inmates, who otherwise would be extremely dangerous and destructive in a yellow-sun environment, and to shelter Mon-El, he apparently privately harbors concerns about the justness of its penal use. This is illustrated in the acclaimed story "For the Man Who Has Everything" by Alan Moore and Dave Gibbons, where Clark is ensnared in a fantasy illusion created by an alien parasitical plant called a Black Mercy. As his subconscious resists the illusion of a peaceful life on Krypton, among the first signs of its degeneration is the sight of his cousin, Kara Zor-El, hospitalized after being attacked by an anti-Phantom Zone militant who left literature protesting that the Phantom Zone is a method of torture.

In the Steve Gerber miniseries The Phantom Zone #1-4 (January–April 1982), it is revealed that the Zone not only has a breach through which other inmates had escaped, but that they were never heard from again.^[6] The imprisoned Superman and Quex-Ul use this method and travel through several dimensional "layers" seeking the exit into the physical universe. They finally encounter a Kryptonian wizard named Thul-Kar, who tells them that he believed Jor-El's prophecy of Krypton's doom and entered the Phantom Zone through magic. Using the same breach, he discovered the truth about the Phantom Zone: all its levels are manifestations of the consciousness of a sentient, malevolent entity called Aethyr, The Oversoul.

As explained by Thul-Kar, Aethyr itself came into being uncounted millennia ago when two spiral galaxies collided at an almost primordial stage after the physical universe's creation. Countless worlds were simultaneously destroyed and the deaths of so many beings merged somehow to form a single, evil consciousness that called itself Aethyr The Oversoul. This supremely powerful entity enclosed itself into a dimension outside the physical universe within itself, forming the Phantom Zone.

The Zone itself is an interface between the Earth-One dimension (the physical universe) and Aethyr's mind, the outer layer (where zone criminals are housed) representing its ability for abstract thought; the Zone is basically Aethyr's capacity to imagine other possibilities of existence, and is the outermost template of its consciousness. Only by entering Aethyr's core realm can a zone prisoner escape back to the physical universe, but this process is dangerous since any being who tries risks being destroyed in numerous ways as well as by forever having their souls merged with Aethyr's essence while within Aethyr's core realm.^[7] This is because as someone enters deeper into Aethyr's consciousness, then no longer exist as an abstract entity and its existence becomes subject to Aethyr's whims. When attacking Superman and Quex-Ul, Aethyr personified itself as an aggressive, purple-skinned dog's head that breathed flames capable of destroying and absorbing the souls of those that it wishes to conquer. While Quex-Ul is killed by Aethyr in this fashion, Superman manages to make his way out of the Phantom Zone by avoiding those flames and flying directly through Aethyr's skull and its mind, returning to Earth through a tear in the fabric of Aethyr's mind and the physical universe, but not without encountering the horrific remains of all of the souls entrapped within Aethyr over the millennia.^[8]

Mister Mxyzptlk is later possessed by Aethyr. During the process while Mxyzptlk is imprisoned on his own home dimension, Thul-Kar communicates with Mxyzptlk and offers him an escape in exchange for the merger. This merger, however, empties the Phantom Zone of its criminal inhabitants. As the Phantom Zone villains head to Earth to conquer it, Thul-Kar and Nam-Ek are re-absorbed into Aethyr. Superman awakes and sees that the Phantom Zone villains are wreaking havoc on Earth, causing destruction to the Capitol Building in Washington, D.C., and demanding Superman come out and fight them. Superman battles the Phantom Zone villains in Washington D.C., While fighting Faora Hu-Ul, he witnesses her disappearing as she is absorbed into Aethyr. Mister Mxyzpltk reveals that his strong personality has taken over Aethyr and he absorbs all the rest of the Phantom Zone inhabitants back into himself, determined to torture them endlessly and wreak havoc as he sees fit. Mxyzpltk-Aethyr leaves, intending to next take over the Fifth Dimension, and Superman is left to put out the fires in Washington and then rid Metropolis of the Kryptonite remains of Argo City.^[9]

In the Post-Crisis DC Universe, the Phantom Zone first appears after Superman returns from space with a Kryptonian artifact called the Eradicator. This device, created by his Kryptonian ancestor Kem-L, attempts to recreate Krypton on Earth, building the Fortress of Solitude; the extradimensional space in which the Eradicator finds the Kryptonian materials necessary is called the Phantom Zone.^[10][11] A Phantom Zone Projector is part of Superman's current Fortress. It has been used to access the Bottle City of Kandor and to trap villains such as the White Martians.

The Phantom Zone has been independently discovered by various characters where it is called the "Buffer Zone" by the Bgztlians, the "Still Zone" by the White Martians, the "Stasis Zone" by Loophole, the "Ghost Zone" by Prometheus, and the "Honeycomb" by the Queen Bee I. In Post-Crisis/Post-Zero Hour continuity, it was Loophole's "Stasis Zone" technology that exiled Mon-El, known in the new continuity as Valor/M'Onel, into the Phantom Zone for 1,000 years.

Superman fashions the Phantom Zone technology into an arrow projectile which upon striking a victim will project them into the Phantom Zone. Roy Harper, the original Speedy, steals this arrow from Superman when the original Teen Titans are invited for a visit many years ago. Roy, however, never uses the arrow and passes it on to his replacement, Mia Dearden, who uses the arrow during the events of Infinite Crisis on Superboy-Prime. He is too strong for even the Phantom Zone arrow, and manages to break out.

At one point, the White Martians imprison Batman in the Phantom Zone and take his identity as Bruce Wayne.

Batman devises a measure made after Superman recovers from his first battle with Doomsday, that, when the Justice League or any other superhero groups encounter a Doomsday Level Threat, a group of heroes, authority, and military forces will contain it within a proximity after clearing all civilians within it. If Superman and the rest fall, the Doomsday Protocol will commence by sending it to the Phantom Zone.^[12]

In Action Comics, General Zod, along with Ursa and Non, appear in search of the son of Zod and Ursa.^[13]

Supergirl #16 shows a form of life native to the Phantom Zone. These Phantoms are enraged over the use of their universe to house criminals and seek revenge on the one responsible.^[14]

During the "New Krypton" storyline, the Kryptonians in Kandor have started to take matters into their own hands and started rounding up some of Superman's enemies to throw them into the Phantom Zone. First, they attack the Science Police where they make off with the Parasite. The second target is Silver Banshee who the Kandorians chase across the skies. At Arkham Asylum, the Kryptonians knock out Nightwing and Robin where they make off with Toyman while another group knocks out Black Lightning to claim Toyman. Bizarro is even attacked by Thara's group while flying. While Superman, Supergirl, and Zora are disgusted at what some of the Kandorians did and demands the ones responsible to turn themselves over to the authorities, Alura would not cooperate and gives the orders to throw the villains that they rounded up into the Phantom Zone.^[15] Those who were thrown into the Phantom Zone were later freed by Superman.^[16]

In the miniseries 52 the Phantom Zone is ingested by Mister Mind while he is mutating into a giant insect form. Once full-grown, Mind regurgitates it in an attempt to destroy Booster Gold and Rip Hunter, but the attack is deflected by Supernova, who returns the Phantom Zone to its proper dimensional plane. Supernova is able to control the Zone as his supersuit's powers are based upon Phantom Zone projector technology stolen by Rip Hunter.

In Action Comics #874, the Phantom Zone vanished.^[17] Action Comics #886 offers a possible explanation as to the Phantom Zone's disappearance, the theory being that the Phantom Zone was actually the mythical Nightwing, counterpart to the Flamebird, imprisoned in an altered state of being. Having chosen a new Avatar, Chris Kent, who was freed from the Zone, he too would have been freed from his shackles, thus causing the Phantom Zone to cease to exist.^[18]

In Adventure Comics (vol. 2) #11, the Phantom Zone is recreated by Chameleon Boy and Superman.^[19]

In The New 52, Jor-El suggests going into the Phantom Zone when Krypton was about to explode. Zod, however, appears with other Phantom Zone prisoners and attempts to escape the Phantom Zone. Krypto sacrifices himself by attacking Xa-Du, thus going into the Phantom Zone as well.^[20]

It is revealed that Doctor Xa-Du was the first Kryptonian prisoner to be sent to the Phantom Zone due to his forbidden experiments in suspended animation, with Jor-El executing the sentence. The Phantom Zone is reverted to the Pre-Crisis version.^[21]

During the Dark Days: Metal event of the DC Rebirth reboot, Superman has theorized that the Phantom Zone might be actually a permeable membrane between Earth-0 (DC Universe) and the Dark Multiverse.^[22]

Throughout the Silver Age of Comic Books, the following inhabitants of the Phantom Zone have been depicted. Based on this list, at least 34 Kryptonians were projected into the Phantom Zone on Krypton over a period of less than 256 Kryptonian days.^[23] The entry on the Kryptonian Calendar shows the details on the relationship between Kryptonian sun-cycles and Earth years.

• Ak-Var – Ak-Var was sentenced to approximately 30 Earth years (22 Kryptonian sun-cycles)^[a] in the Phantom Zone for plotting to steal a revered relic called a Sun-Stone from a museum. After he had served his full sentence, Ak-Var was released by Superman and brought to the bottle-city of Kandor. Ak-Var became the lab assistant of Superman's cousin, Van-Zee.^[24] Sometime later, Van-Zee adopted the costumed identity of Nightwing and Ak-Var became his partner Flamebird.^[25]
• Ar-Ual – Ar-Val was sentenced to 50 Kryptonian sun-cycles (68.5 Earth years) in the Phantom Zone for destroying priceless knowledge and depriving Krypton of 1,000 years of scientific progress. When an alien space warship that was approaching Earth exploded, the blast opened a temporary rift in the Zone. Ar-Val escaped the Zone, captured and imprisoned Wonder Woman, then impersonated her so that she could trick Superman into marriage. Ar-Val figured that Superman would never suspect his wife of ruling the crime world. Superman uncovered her deception and returned her to the Phantom Zone.^[26]
• Az-Rel – Az-Rel was a petty criminal from Bokos, the Island of Thieves. He possessed pyrotic powers. His partner, Nadira, possessed psychokinetic powers. Together they robbed helpless victims in Erkol, the oldest city of Krypton. Both were captured and sentenced to 15 Kryptonian sun-cycles (20.55 Earth years)^[b] in the Phantom Zone. The two criminals were among those freed from the Zone when Quex-Ul was manipulated into building and activating a crude Phantom Zone Projector.^[27] Later, Nadira was killed when the dying Jer-Em exposed her to green kryptonite. In her dying agony, Nadira telekinetically inflicted pain on Az-Rel, which unleashed his pyrokinesis upon himself, incinerating him.^[8]
• Bal-Gra – The history and sentencing of this prisoner was not revealed. Bal-Gra once escaped from the Phantom Zone through a temporary space-warp. He boasted to Superman that he was the strongest man on Krypton. Lois Lane managed to expose Bal-Gra to Gold Kryptonite, which permanently robbed him of his superpowers. He was then sent back into the Zone by Lorraine Lewis, a brilliant scientist who had built her own Phantom Zone projector.^[28]
• Blak-Du – The history and sentencing of this prisoner was not revealed. Blak-Du was Jor-El's roommate at Krypton College, and was rated as scientifically brilliant.^[29]
• Cha-Mel – A clever youngster who developed a secret spray that enabled him to control his appearance. He turned to crime, but made the fatal mistake of impersonating Jor-El and attempting to rob his house. Jor-El returned home too soon and foiled Cha-Mel's attempt. The young thief was sentenced to the Phantom Zone for his crime. Years later, Cha-Mel managed to take the form of Superboy and trick the real Superboy into entering the Zone. Cha-Mel then manipulated Superboy's parents into freeing him. He tried to secure the Phantom Zone projector to free the other prisoners, but the device was destroyed in a tug-of-war with Krypto, returning him to the Phantom Zone while freeing Superboy.^[30]
• General Zod^[c] – He was sentenced to 40 Kryptonian sun-cycles (54.8 Earth years) for using a duplicator ray to create a private army of imperfect clones (Bizarros) to overthrow the government.^[31]
• Erndine Ze-Da (Zeda)^[d] - The history and sentencing of this prisoner was not revealed. One day, a South Seas volcano exploded and the concussion opened a temporary gap in the Phantom Zone, enabling both Erndine Ze-Da and Dr. Xadu to escape. They concocted a plan to trap Superboy in the Zone, but he became aware of their scheme and stranded them on the planet Exon.^[32] Years later, Erndine and Dr. Xadu, who had since married and acquired the secret of the cosmic power-grip, escaped from Exon and returned to Earth. Superman defeated them again, and placed them in separate cells on two different worlds.^[33]
• Faora – A martial arts expert and hater of males, who was sentenced to 300 Kryptonian sun-cycles (411 Earth years) in the Phantom Zone for causing the deaths of 23 men in her own concentration camp. She once escaped captivity by using telepathy to manipulate an Earthman named Jackson Porter into freeing her from the Zone.^[34]
• Gann Artar – In one imaginary story, a criminal named Gann Artar was sentenced to 50 Kryptonian sun-cycles (68.5 Earth years) for using his de-evolutionary ray to create large, dangerous monsters.^[35]
• Gaz-Or (AKA The Mighty Gazor)^[e] – After a lifetime of scientific villainy and because he was dying of old age, the Mighty Gazor attempted to use his earthquake machine to destroy Krypton. He was stopped by Jor-El, who had arrived just in time and was sentenced to the Phantom Zone for his crime. Gazor claimed that he had received the longest sentence ever given to anyone condemned to the Phantom Zone. This contradicts the fact that Jax-Ur and Orn-Zu both received life sentences, but after Mon-El was released from the Zone in the 30th Century, Gazor was indeed the only prisoner remaining in that ghostly dimension.^[5]
• Gor-Nu – Once the greatest biochemist on Krypton, Gor-Nu's reckless experiments caused several deaths. He was sentenced to 50 Kryptonian sun-cycles (68.5 Earth years) in the Phantom Zone. When a lethal crystal-menace threatened to destroy the bottle-city of Kandor, Superman released Gor-Nu in the hope that he could figure out a way to stop it. Gor-Nu was successful, but he then tried to betray Superman. Gor-Nu's plans were foiled and he was returned to the Phantom Zone.^[36]
• Gra-Mo and two assistants – The criminal Gra-Mo and his two assistants (one possibly named Ni-Van^[f]) were captured, sentenced to life for attempting to take over Krypton with Gra-Mo's robot hordes, placed in suspended animation, and imprisoned in a space capsule which was placed into orbit around Krypton. They were the last criminals to receive this type of punishment. After Krypton's destruction, the capsule drifted through space, and they eventually awakened and traveled to Earth. When Superboy learned of their criminal nature, he figured out a way to defeat them and projected them into the Phantom Zone.^[37]
• The Inventor – The history and sentencing of this non-Kryptonian prisoner was not revealed.^[38]
• Jackson Porter of Earth – Phantom Zone prisoner Faora used telepathy to delude Jackson Porter into believing she was the ghost of his dead wife Katie. Faora soon manipulated him into freeing her from the Phantom Zone. After she was returned to her prison, the permanently deluded Jackson chose to follow her into the Phantom Zone.^[34]
• Jax-Ur – A rogue Kryptonian scientist who was sentenced to an eternity in the Phantom Zone for breaking the law forbidding anyone to experiment with an untested explosive. His rocket missed its target and destroyed Wegthor, an inhabited moon of Krypton, killing 500 colonists. He was the first prisoner projected into the Phantom Zone on Krypton. Jax-Ur also became the first prisoner to escape the Phantom Zone when a passing comet created a momentary warp through which he slipped.^[39]
• Jer-Em – A religious fanatic who was sentenced to 30 Kryptonian sun-cycles (41.1 Earth years) in the Phantom Zone for wiping out the superpowers of the people of Argo City (the birthplace of the future Supergirl) by guiding it back toward a red sun, leaving the residents stranded in their city in space.^[40] Jer-Em was among those freed from the Phantom Zone when Quex-Ul was manipulated into building and activating a crude Phantom Zone Projector.^[27] Later, Jer-Em purposely exposed himself to Green Kryptonite to enter the Kryptonian afterlife.^[8]
• Kru-El – A weapons designer and cousin of Jor-El^[g] (the father of the future Superman). He was sentenced to 35 Kryptonian sun-cycles (47.95 Earth years) for developing an arsenal of super-powerful, forbidden weapons.^[41][h]
• Kur-Dul – The history and sentencing of this prisoner was not revealed. Kur-Dul served his full sentence^[42] and was released by Superman and the Kandorian parole board.^[36]
• Lar Gand of Daxam (Mon-El) – A superpowered youth arrived on Earth with amnesia. He was found by Superboy, who suspected the youth may be his older brother. Superboy named him Mon-El, because they met on a Monday. When Mon-El was later exposed to lead, he collapsed in pain. His memory returned, and he explained that he is from the planet Daxam, whose natives have a lethal vulnerability to lead. To save Mon-El's life, Superboy projected him into the Phantom Zone.^[43] Mon-El spent 1,000 years in the Zone before he was released and cured by the Legion of Super-Heroes.^[44]
• Lar-On – Lar-On found himself inflicted with a werecreature disease for which there was no known cure. He was sent into the Phantom Zone by Jor-El until a cure could be found for the disease. Lar-On was later unwittingly freed by a scientist named Professor Jeremiah Terry when he attempted to create a portal to Earth-Two. Lar-On was captured by Superman and Batman, who returned him to the Zone.^[45]
• Lester Wallace of Earth – After being mentally manipulated by the Phantom Zone prisoner Zan-Em into developing a deep hatred of aliens and causing him to betray Superboy, Lester Wallace realized he had become the very thing he despised. He projected himself into the Phantom Zone as punishment.^[46]
• L. Finn – The history and sentencing of this non-Kryptonian prisoner was not revealed.^[38]
• Lois Lane of Earth – Lois Lane time-traveled back to Krypton before it exploded and was accidentally trapped in the Phantom Zone by Jor-El when he was testing his new Projector device. She spent more than two and a half decades there before she was discovered and released by Superman.^[47]
• Marok – The history and sentencing of this prisoner was not revealed.^[47]
• Murkk – The history and sentencing of this prisoner was not revealed.^[48] Murkk was among a group of Phantom Zone prisoners who escaped by focusing their mental energies on a piece of Jewel Kryptonite. He was later disintegrated by the Vrangs.^[49]
• Nadira Va-Dim^[i] – Nadira was a petty criminal from Bokos, the Island of Thieves. She possessed psychokinetic powers. Her partner, Az-Rel, possessed pyrotic powers. Together they robbed helpless victims in Erkol, the oldest city of Krypton. Both were captured and sentenced to 15 Kryptonian sun-cycles (20.55 Earth years)^[50] in the Phantom Zone. The two criminals were among those freed from the Zone when Quex-Ul was manipulated into building and activating a crude Phantom Zone Projector.^[27] Later, Nadira was killed when the dying Jer-Em exposed her to green kryptonite.^[8]
• Nam-Ek – Rondors were hideous, foul-smelling Kryptonian beasts whose horns radiated a natural healing ray. So valuable were the animals that their slaughter was outlawed. 500 years ago, Nam-Ek, a Kryptonian scientist, killed two Rondors so that he could study their horns' powers. He extracted a serum from the healing horns, which would grant immortality. When four people died because no Rondors were available, he was charged with murder. He evaded capture and drank the serum. In the next instant, he mutated into an immortal humanoid Rondor. 500 years later when Krypton exploded, Nam-Ek was left drifting in space.^[51][j] Nam-Ek was later retrieved by Amalak the Kryptonian-Killer, who attempted to kill him, but discovered that it was impossible. When Amalak's spaceship entered a yellow sun-system, Nam-Ek gained superpowers and headed to Earth to warn Superman. After Amalak's defeat, Nam-Ek was projected into the Phantom Zone by Superman because he had been exhibiting dangerous bouts of insanity.^[52]
• Orn-Zu – Believing that Krypton's sun would soon go nova, Orn-Zu created Jorlan, an android designed to hypnotically lure children away. He intended to use it to save his world's youth by kidnapping them and taking them away from Krypton. Orn-Zu was sentenced to an eternity in the Phantom Zone. When Jorlan arrived on Earth, it attempted to complete its mission.^[53] Orn-Zu convinced Superman to release him from the Zone, and they both confronted the android. Already dying from Pythagra Fever, Orn-Zu sacrificed his life to help stop his creation.^[54]
• Py-Ron (Evil-Man) – Py-Ron was sentenced to 50 Kryptonian sun-cycles (68.5 Earth years) in the Phantom Zone for using forbidden experiments to turn humans into weird, bird-like monsters. Years later, a volcanic eruption freed Py-Ron from the Phantom Zone. He donned a costume and harassed Superman, using the name Evil-Man. Superman soon captured Py-Ron and returned him to his prison. A few years after that, when Supergirl was forced through hypnosis by the Sisterhood of Evil to test a deadly poison on a super-human, Py-Ron agreed to be her test subject. When Py-Ron appeared to die, Supergirl was then forced to give the poison to Superman and herself. Luckily, Comet the Super-Horse had learned of the poison and altered it with his X-ray vision so that it only put the victims into suspended animation for a few hours. When Py-Ron woke up, he tried to earn his right to stay out of the Zone by flying to Feminax, the Sisterhood's homeworld, and killing everyone in retaliation. For his heartless action, Superman projected Py-Ron back into the Phantom Zone.^[55]
• Quex-Ul (Charlie Kweskill) – Quex-Ul was sentenced to nearly 25 Earth years (18 Kryptonian sun-cycles) in the Phantom Zone for slaying the rare Rondors and cutting off their radiant, curative horns. He was the last prisoner projected into the Phantom Zone on Krypton. When he served his full sentence, Quex-Ul notified Superman and was released. Quex-Ul intended on getting revenge on Jor-El, the man who sentenced him to the Phantom Zone, by exposing his son Superman to Gold Kryptonite. When Superman proved that Quex-Ul was innocent, having been framed by Rog-Ar, Quex-Ul attempted to stop Superman from being exposed. Quex-Ul inadvertently exposed himself and was robbed of his powers and his memory.^[56] Clark Kent set Quex-Ul up with a job at the Daily Planet using the alias Charlie Kweskill.^[27] Quex-Ul later sacrificed his life in a battle against the entity called Aethyr.^[8]
• Ral-En – A college friend and associate of Jor-El and son of the famous psychologist Mag-En. With the help of his father, Ral-En used hyper-hypnotism to make everyone believe that he had gained superpowers, then attempted to become ruler of Krypton. Jor-El exposed his scheme, and Ral-En was sentenced to the Phantom Zone.^[57] The existence of both baby Kal-El (Superman) and the city of Kandor were crucial to this story. Since Kandor was stolen by Brainiac before the birth of Kal-El and the invention of the Phantom Zone projector, this entire story is impossible.^[58]
• Ran-Zo – The history and sentencing of this prisoner was not revealed.^[47]
• Ras-Krom – The history and sentencing of this prisoner was not revealed. Ras-Krom was a superstitious Kryptonian criminal who escaped the Phantom Zone when an atomic blast opened a small gap between worlds. He attempted to release the other prisoners, but was outwitted and re-imprisoned by Superman and Jimmy Olsen.^[59]
• Roz-Em – The criminal Roz-Em had plastic surgery to look exactly like Nim-El (Jor-El's twin brother). He attempted to steal a valuable weapon from the Armory of Forbidden Weapons, but was captured by Jor-El and the real Nim-El. He was placed in suspended animation, and imprisoned in a space capsule which was placed into orbit around Krypton.^[k] After Krypton's destruction, the capsule drifted through space, and Roz-Em eventually awakened and traveled to Earth. He planned on getting his revenge on Nim-El's nephew, Superboy, by pretending to be a Superman created from Superboy's exposure to Red Kryptonite. Superboy discovered Roz-Em's ruse and projected him into the Phantom Zone.^[60]
• Shyla Kor-Onn^[l] – A brilliant scientist named Shyla Kor-Onn was sentenced to one Kryptonian sun-cycle (1.37 Earth years) for the crime of manslaughter. She was trapped in the Phantom Zone well past her punishment period due to Krypton's destruction. After countless failures, Shyla predicted that she could use her mental powers to manipulate a jet pilot into flying his plane in a specific manner which would create a rip in the Zone. She escaped from her prison and battled Supergirl. When Shyla attempted to use the Phantom Zone Projector in Superman's Fortress of Solitude to free the other Phantom Zone prisoners, Supergirl was able to project her back into the Zone.^[61] A short time later, Shyla was freed in the bottle-city of Kandor, where she attempted to get her revenge on Supergirl.^[62]
• Tal-Var of the Dark Dimension – Jimmy Olsen accidentally released the evil Tal-Var from the Dark Dimension. He intended to loot and lay waste to the Earth, then to trap and kill Superman. Using his wits, Jimmy was able to project the alien into the Phantom Zone before he could carry out his threats.^[63]
• Thul-Kar – The last of the Wizards of Juru, Thul-Kar used magic to teleport himself into the Phantom Zone on the day of Krypton's destruction. He was the first to discover the Phantom Zone's connections to the entity called Aethyr.^[7]
• Tor-An – Condemned to the Phantom Zone for carrying out forbidden experiments transferring the minds of a Kryptonian family into the bodies of monsters. Years later, he instructed a group of Phantom Zone prisoners to use their combined mental powers to prompt the Mayor of Midvale to ask Supergirl to perform a feat which would open a small rift in the Zone. The handsome Tor-An escaped and tricked Supergirl into marrying him. When he began to gloat that she would now be forever disgraced, he learned to his dismay that the marriage was invalid and that he himself had been tricked by Supergirl. He was quickly captured and returned to his prison.^[64]
• The Toyman – The history and sentencing of this non-Kryptonian prisoner was not revealed.^[38]
• Tra-Gob – The leader of a band of Kryptonian thieves which raided the priceless Science Archives. He was betrayed by his own men, but was rescued by Jor-El before they could exterminate him. Tra-Gob was sentenced to nearly 40 Earth years (29 Kryptonian sun-cycles) for his crime, but still remained deeply grateful to Jor-El. Tra-Gob was in the Phantom Zone for nearly 30 Earth years^[a] before he escaped due to a freak disruption by the aurora borealis. He rescued Superman and Lois Lane from a Kryptonian monster, repaying his debt to Jor-El. As Tra-Gob was being returned to the Zone to finish out his sentence, Superman commented that he may be pardoned in Kandor for his good behavior.^[65]
• Tyb-Ol – The history and sentencing of this prisoner was not revealed.^[48] Tyb-Ol was among a group of Phantom Zone prisoners who escaped by focusing their mental energies on a piece of Jewel Kryptonite. He was later disintegrated by the Vrangs.^[49]
• Professor Va-Kox (Professor Vakox)^[m] – Va-Kox is a mad geneticist who was sentenced to 50 Kryptonian sun-cycles (68.5 Earth years) for tossing a test tube full of his life force experiment into the Great Krypton Lake, creating a huge mutated monster.^[66]
• Vax-Nor – The history and sentencing of this prisoner was not revealed. Vax-Nor served his full sentence^[42] and was released by Superman and the Kandorian parole board.^[36]
• Vorb-Un – Vorb-Un was sentenced to 10 Kryptonian sun-cycles (13.7 Earth years)^[67] in the Phantom Zone for experimenting with forbidden elements without the Science Council's permission. During a parole hearing in Kandor, Vorb-Un explained to Superman and the parole board that his sentence was almost up, and he insisted that he had repented. Due to his advanced age and his sincere remorse, he was released from his prison.^[68]
• Vor-Kil – The crime and sentencing of this prisoner was not revealed. Vor-Kil escaped from the Phantom Zone when sunspot activity opened a temporary gap to Earth.

In the Elseworlds tale Superman & Batman: Generations, Superman is sentenced to the Phantom Zone in 1989 when he is stripped of his powers in a confrontation with the Ultra-Humanite that ends with his foe's death, after the Ultra-Humanite's actions led to the death of Superman's wife Lois Lane and his son Joel being tricked into killing Superman's daughter Kara before Joel dies himself, as well as arranging various 'accidents' for Clark Kent's other remaining loved ones. The judges reason that even if Superman feels that he may have killed his foe deliberately after the deaths of his family and friends, putting him in a conventional prison without his powers would be dangerous and solitary confinement was too extreme given his past deeds, selecting the Zone based on the suggestion of the new Batman, Bruce Wayne Junior. Superman is released in 1999 by the now-rejuvenated Bruce Wayne as Bruce returns to the role of Batman - Bruce noting that he is ending the sentence a few months early but is certain that nobody would object to early release "for good behavior" - although Superman was briefly able to appear as a phantom in the real world in 1997 to distract a foe who was about to kill Knightwing (Superman's grandson, adopted by Batman's son after the deaths of Superman's children).

There had been similar Zones that were in comparison to the Phantom Zone:
