Underworld Unleashed was a multi-title comic book crossover event released by DC Comics in 1995. As well as the core storyline of the three-issue Underworld Unleashed miniseries (November 1995-late December 1995), most of the issues of the DC Comics titles that were published in November and December 1995 (including two in October 1995 and one in January 1996) and four one-shot issues that were published at the same time were also part of the event.
The main theme of Underworld Unleashed involved the then-new ruler of Hell, a demon-lord named Neron, offering many of the DC Universe supervillains and a number of the DC Universe superheroes various deals-in which they would be given their greatest desires in exchange for their souls or for completing a task for him-and the consequences of those deals.
Underworld Unleashed is one of the very few major DC Comics crossover events not to directly involve Superman; at the time of the event he was off-world and in outer space as part of a crossover storyline in the Superman comics called "The Trial of Superman!" (November 1995-January 1996). This is important to the Underworld Unleashed crossover event, since the superheroes involved are driven by the belief that Superman is the key to Neron's plans.

Five members of the Flash's Rogues Gallery-Captain Boomerang I, Captain Cold, Heat Wave, the Mirror Master II and the Weather Wizard-are approached with an offer by fellow Rogue Abra Kadabra, who had become an agent of the demon Neron in exchange for true magical powers to replace his technology-based magical powers. Abra Kadabra persuades them to cause havoc by destroying five separate targets (an arms depot by Captain Boomerang I, a nuclear reactor by Captain Cold, a dormant volcano by Heat Wave, an oil field by the Mirror Master II and a chemical dump by the Weather Wizard) simultaneously, with the promise of "respect" and "a guarantee that they would be remembered forever, not as has-beens but as the most infamous villains of their age". But Neron's deals are demonic, twisted and unfair and they were not told that their actions would cost them their lives and unleash Neron upon Earth. All five are killed in the ensuing explosions (which consume them in green fire), all of which form the points of a pentagram that creates a gateway which releases Neron.
Soon after this, Neron kills the Chaplain of Belle Reve Penitentiary and then, disguised as the Chaplain, accompanies Father Richard Craemer, a priest who administers to the prisoners of Belle Reve (as well as being an advisor to the Suicide Squad and a friend and counsellor to the Spectre I), on his rounds at the prison. He next makes a deal with Lou Krupke, one of the inmates (who is bent on revenge for the theft of a treasured calendar that he believes to have been stolen by a Belle Reve guard named Finney), in exchange for a gun that he had bought earlier before entering Belle Reve. Neron himself had already stolen the calendar in question in order to engineer the situation and he also makes deals with a number of key Belle Reve personnel or persuades/manipulates them in other ways to be absent that evening. Krupke kills Finney with the gun and, at the same time, damages the electrical turbines that give Belle Reve its power. The resulting chaos allows 142 supervillains to escape from Belle Reve. When it is all over, Neron claims Krupke's soul.
A few weeks later, another member of the Rogues Gallery, the Trickster I, reads of the deaths of his fellow Rogues and determines not to waste any more time on petty crimes, but to finally make a major supervillain of himself. One week after the Trickster I's decision another Rogue, the Rainbow Raider III, shows him a carved black candle that he and other recently escaped supervillains had received, with instructions to light it at midnight on a certain day to "open the door to fame, power and glory". The Trickster I steals the candle, secretly replaces it with a rubber chicken and upon lighting it is instantly transported to Hell, joining over 60 other supervillains who had done the same. Neron appears to the gathered supervillains and offers them all their greatest desires in exchange for their souls, then introduces his "Inner Council" -Lex Luthor, the Joker, Circe I, Doctor Polaris I and Abra Kadabra. The Fiddler II figures out immediately that Neron is actually the devil himself and the Trickster I overhears him; then several dozen of the supervillains accept Neron's offer while the rest who rejected it are returned to Earth by him (with the exception of one-Mongul I-whom Neron kills with his bare hands and takes his soul after the alien tyrant refuses to make a deal and attacks him because he believes that Neron has insulted him by calling all of the assembled supervillains-including him-failures before Neron came into their lives). As each supervillain accepts the offer, their souls (which look like green vapor) are collected in a large clear container called the Soul Jar. Neron then sends the newly-empowered supervillains who accepted his offer (with the exception of his Inner Council and the Trickster I) back to Earth to fulfill their sides of their deals, seek revenge on the superheroes and wreak havoc. At the end of all this, Justice League America member Blue Devil, a former friend of the Trickster I who had worked out that the locations of the deaths of the five Rogues Gallery members formed the points of a pentagram, appears. He is offered fame and fortune in exchange for performing a simple task: the destruction of an unmanned electrical power station.
While the supervillains empowered by Neron proceed to run amok with their new powers, Neron then turns his attention to Earth's superheroes. In addition to trying to gain the souls of the Batman I, the Flash III and an unknown number of other superheroes, Neron offers to resurrect Alexandra "Alex" deWitt from the dead in exchange for Green Lantern V's (Kyle Rayner's) soul. Kyle refuses and after Neron defeats him in battle he spares his life, giving Kyle the message that what he covets most of all is "a far more noble soul" who Kyle knows and that when he has it, Earth will be his. Kyle assumes this means Superman (who is off-world because of his trial in outer space) and carries the message to the Refuge, Justice League America's space station headquarters.
Meanwhile, Neron causes further disruption on an Earth now seething with violence and war as a result of his demonic influence on people and the chaos caused by the supervillains who are now in his debt. He also spreads chaos on New Apokolips just for the sake of doing so, giving all those who desire the missing-and-presumed-dead Darkseid's throneinformation on each other's plans, thus causing New Apokolips to wage war with itself. Back in Hell, Luthor and the Joker force the Trickster I to reveal that Neron's power is contained within his Soul Jar and succeed in rupturing the Jar using Circe I, Polaris I and Kadabra's magical and scientific resources together. As the Jar is breached a swirl of green vapor reaches outward, then picks up Circe I, Polaris I and Kadabra and pulls them right into the Jar, after which the Jar reseals, which is what Luthor and the Joker had actually planned all along. However, Neron had preempted them by fooling the Trickster I into giving them false information, thus removing his Inner Council completely before they could become a threat to his power. He shrinks Luthor and the Joker in size and traps them in a snow globe-although they both believe that they are in a snowstorm in Metropolis until they reach the glass walls of the globe.
As Earth collapses into violence, war, anarchy and chaos, Justice League America calls most of the world's superheroes together to stand against Neron. Like Kyle, all of them assume that because he is missing, it is Superman that Neron referred to as the pure soul that he wanted and that he had already been captured. The elite of Justice League America decide to take the fight to Neron and Blue Devil, who had been fooled by Neron's Faustian deal into indirectly causing the death of his friend, filmmaker Marla Bloom, takes them to Hell. Now alone in Hell after the fall of the Inner Council, the Trickster I, who had not yet been offered a deal for his soul, realizes that he had been taken for a fool, that no deal was forthcoming for him at all and that Neron had deeper plans that he had not revealed to him. He begins to scheme against him.
On Earth, Doctor Fate I's (Kent Nelson) home, the Tower of Nabu, has become a portal to Hell that the demoness Blaze is trying to secure so that Neron can send Hell's demonic forces to Earth. Sentinel and Fate IV (Jared Stevens) fight to close the portal, Sentinel destroying the tower to do so. While Fate IV battles back from being flung into far dimensions, Sentinel is drawn away from his wife Molly Catherine Mayne-Scott, a.k.a. the Harlequin I, who opens a box containing one of Neron's candles and accepts a deal to become young again and to have the power to create nightmares, losing her soul in the process. Sentinel contacts the Phantom Stranger, Zatanna Zatara and James Brendan "Jim" Corrigan I (a.k.a. the Spectre I, but without his full powers, as the Spectre-Force within Corrigan I had made a deal with Neron for a separate existence from its host) for help. Together with Deadman, they enter Hell to get Molly's soul back from Blaze. The Spectre I tries to help, but discovers that his deal keeps him from opposing Neron and, as a result, he is Neron's slave and is also destined to become his successor. Realizing that he is not prevented from fighting other demons, however, he joins the others in the battle and Sentinel frees Molly's soul in exchange for his own. Blaze is forced to flee from Neron for failing to stop the supernatural team and while the magical superheroes escape, Sentinel is captured by Neron and imprisoned in Hell inside a jewel worn around Neron's neck.
Using what is left of Blue Devil's candle, Justice League America pierces the barrier to Hell and confronts Neron's demonic army, battling through the realms of Hell to find Superman. The Ray II, Firestorm the Nuclear Man II (Ronald Roy "Ronnie" Raymond), Captain Atom II and Maxima are all killed in the battle, while the other superheroes (except for Captain Marvel) begin to be corrupted by the influence of their hellish surroundings. Meanwhile, the demon Satanus bargains with Neron in the throne room of Hell for the return of his soul after failing in his task to stop the Leymen of Primal Force publicly, offering up the whereabouts of his sister Blaze in exchange; but once his soul is returned to him and Blaze is imprisoned by Neron, he reveals to her that Neron can be beaten by a single word that if spoken, even in Hell, would give even Neron pause. For this betrayal Neron kills Satanus, though not before his comment is overheard by the Trickster I. At that moment Blue Devil, seeking revenge for the death of Marla, finally reaches Neron ahead of Justice League America and is killed by him; after which the superheroes (again, except for Captain Marvel) become completely evil upon entering Hell's throne room and Neron reveals that it was Captain Marvel's soul that he wanted all along, just as the Trickster I realizes the truth.
Neron has kept Blaze alive because her demonic powers dampen Captain Marvel's powers. She reverses this by augmenting his powers instead, saving him from death; while Blue Devil, who cannot die while he is in Hell, attacks Neron in a new demonic body. Taking advantage of the diversion, the Trickster I tells Captain Marvel about the word and Captain Marvel deduces that the word is "Shazam". When he uses it, the resulting lightning bolt in Hell stuns Neron and releases Justice League America from their spell, allowing them to attack him again. Sentinel is also released from his captivity and he joins the other superheroes in the fight. The Trickster I then uses the time provided to persuade Captain Marvel that he has a plan to defeat Neron and quickly tells him what to do. Then Captain Marvel suddenly offers Neron his soul, in exchange for "the release of my friends ... the release of Earth". When Neron asks him "And...?" he says "No "and", nothing else. Nothing". Neron accepts the offer and tries to take Captain Marvel's soul (which looks like pure white light), but because the deal was purely altruistic and self-sacrificing, the first time that someone had ever asked for something without personal gain involved, because he cannot collect on a deal without there being something in it for the one he is dealing with and because Captain Marvel's soul is so pure that even a demon like himself cannot touch it without being actually, physically burned, he cannot do it-then he suddenly realizes that he still has to honor his side of the deal. Taunted by the Trickster I, he disappears in a explosion of green fire, the Soul Jar is shattered (thus releasing its contents-the souls of everyone involved, whether superhero, supervillain or otherwise-and returning them to their rightful bodies (with the exception of the five Rogues, Mongul I and three other dead supervillains who had previously made deals with Neron named Purgatorythe Ice Man and the Buggmeister), the four superheroes who had been killed previously are resurrected from the dead and everyone is returned to Earth, including Luthor and the Joker, who are freed from the shattered snow globe, returned to normal size and sent back to Earth.
At the same time, all of the supervillains who had accepted Neron's offer, in addition to regaining their souls, are allowed to keep their enhanced powers and are no longer in debt to him, although one of them-Major Disaster-while silently gloating about this fact, soon finds out by looking at his reflection in a window that he has the number 666 etched into his forehead (and that only he can see it), thus implying that the rest of them do, too.
Offers of Neron
Superheroes who accepted Neron's offer
- Blue Devil - He was offered fame and fortune in exchange for destroying an unmanned electrical power station, indirectly causing the death of his friend, filmmaker Marla Bloom, who had been scouting the area for a film. The fame and fortune resulted all because he was free to pursue other film opportunities without her.
- The Harlequin I (Molly Catherine Mayne-Scott) - She had her youth restored and was given the power to create nightmares, but her soul was won back and the deal undone by her husband Sentinel (see below) at the cost of his own soul.
- Hawkman III (Katar Hol) - One of his "hawk-avatar" spirits within him sold its soul in order to gain ascendance over the other avatars also resident in his body, but it failed to do so.
- Lobo - He had Neron rid him of a radio that had been implanted in his head for twenty years by wishing it to be inside Neron's head after he refused to accept Lobo's first offer-Neron's own soul-as the demon did not have one.
- Madame Xanadu - She was given the power to command and control three demons named Bathopet, Maw and Atopeh in exchange for her soul when she died. Accepted the offer only in order to trick Neron because she was immortal and, therefore, could not die.
- The Ray II (Raymond C. "Ray" Terrill) - He thought Neron was a beautiful woman, Kathy Noren, who worked in his office. Neron makes a deal with Vandal Savage not to go after the Ray II's soul in exchange for Savage guiding Neron to the Atomic Skull II instead. The Ray II then approaches Kathy/Neron, who avoids the conditions of his deal with Savage by letting the Ray II accept an offer to take flowers to a hospital and give them to Eleanor Hart, the dying serial film actress who had portrayed "Zelda Wentworth" (the Atomic Skull II's one true love (at least in his own mind)), in exchange for Death Masque no longer having existed-and thus the Ray II's father, Lanford "Happy" Terrill (originally known as the Ray I), would not die. Did not fulfill the terms of his deal and so did not lose his soul nor benefit from the deal. Later killed on the way to Hell during the superheroes' battle with Neron there, but resurrected from the dead after Neron is defeated.
- Sentinel (Alan Ladd Wellington Scott (originally known as Green Lantern I)) - He offered his soul to Neron in order to free the soul of his wife, the Harlequin I (see above), who had sold it to Neron previously; this resulted in Sentinel being taken captive in Hell and imprisoned in a jewel worn around Neron's neck. He was later freed from his captivity and joined the other superheroes in the final battle against Neron.
- The Spectre I (James Brendan "Jim" Corrigan I) - The Spectre-Force (not its host, Jim Corrigan I) agreed not to oppose Neron in order to be free of Corrigan I. As a result, the Spectre I became Neron's slave and potential successor in Hell. However, the deal did not include not fighting other demons, so the Spectre I became involved in the magical superheroes' attack on Hell.
- Vril Dox II (a.k.a. Brainiac 2) - He sold the soul of a future descendent of his own family for information on how to regain control of L.E.G.I.O.N. and, using that information, lobotomized his son Lyrl Dox (a.k.a. Brainiac 3), thus removing Lyrl's twelfth-level intelligence and reducing his mind to that of a normal one-year-old child of Earth. Also had the Ice Man killed (actually he asked for him "to no longer be a problem" , but was happy with the result).
- The Warrior (Guy Darrin Gardner (originally known as Green Lantern III)) - He was offered the resurrection of his loved ones and the return of Coast City in exchange for killing Green Lantern IV (John Stewart). He originally agreed because Neron had lied to him, telling him that Stewart should already be dead, but that a rift in time had prevented it and that this had caused the Warrior's tragic history to occur. The Warrior then changed his mind and reneged on the deal.
Superheroes who rejected Neron's offer

She refused, knowing that she would lose her soul anyway, no matter what Neron had promised her.
- The Silver Swan II (Valerie Beaudry) - Unknown offer.
- Superboy (Kon-El a.k.a. Conner Kent) - He was offered the chance to become Superman.
- Triumph - He was offered his lost ten years back and thus the opportunity to become a major superhero and lead Justice League America if he simply opened a box containing one of Neron's candles.
Supervillains who accepted Neron's offer
The following is an incomplete list of the supervillains who are known to have accepted Neron's offer. Others who accepted may have been briefly shown dealing with Neron in Underworld Unleashed #1, but were not followed elsewhere in the miniseries.
- Abra Kadabra - Neron's lieutenant; he was given real magical powers that replaced his technology-based magical powers. Became part of Neron's Inner Council, but was betrayed by fellow Inner Council members Lex Luthor and the Joker. It is not known whether he sold his soul prior to Underworld Unleashed #1.
- The Atomic Skull II (Joseph Martin) - His sanity was restored and he was given enhanced power which he used to attempt to gain the love of "Zelda Wentworth" (who, in his mind, was the woman he loved).
- Azrael VI (real name unknown) - One of the potential successors to the mantle of Azrael who seemingly fell to his death after battling Azrael V (Jean-Paul Valley) was actually saved during his fall by Abra Kadabra (who was acting on behalf of Neron at the time) and offered his life. As a result of his taking the deal he survived the fall, then was given the armored Azrael/Batman costume (which he used for illegal underground fights) and was also given the chance to kill the Batman I in order to distract him and to keep him from discovering Neron's plans.
- Blackguard - He was given enhanced intelligence, strength and equipment.

- Captain Cold - He was promised that he would be one of the greatest supervillains that ever lived. Killed carrying out his task.
- The Cheetah III (Barbara Ann Minerva; has used the aliases Priscilla Rich, Deborah Domaine and Sabrina Ballesteros) - Initially it seemed that the Cheetah III had been transformed into a more cheetah-like form than she had before, with the mind of a wild animal to match, and could grow more savage the angrier she became. Later, it was explained that she had sold her soul to resurrect a friend from the dead, resulting in the aforementioned reversion to a more bestial state. Wonder Woman and the Cheetah III's friend later changed her back into her human form.
- Chiller - He was given a chance to carry out his dream assassination...the murder of a well-protected rock star.
- Chronos I (David Langhorn Clinton) - In exchange for killing the Atom II (Raymond "Ray" Palmer), he was given time travel, time manipulation and phasing powers, but these caused accelerated aging. He then devised a special glove that allowed him to age others instead when he held them with it, thus partly negating the deal.
- Circe I (has used the aliases Cassandra Colchis and Donna Milton) - She was given greater magical powers in order to avenge her many defeats by and to kill Wonder Woman. Became part of Neron's Inner Council prior to Underworld Unleashed #1, but was betrayed by fellow Inner Council members Lex Luthor and the Joker.

- The Joker - He sold his soul for a box of Cuban cigars and seemed to have made the deal just for the sheer fun of it. Became part of Neron's Inner Council prior to Underworld Unleashed #1 but, along with Lex Luthor, double-crossed him and betrayed the other three Inner Council members.
- Killer Frost II (Louise Lincoln) - She was given greater cold power.
- Killer Moth I (Drury Walker; has used the alias Cameron van Cleer) - He was transformed into a carnivorous human-moth hybrid and changed his name to Charaxes (the name was based on an actual butterfly genus). Sold his soul in exchange for being feared instead of being considered a joke.
- Kryppen (full name unknown) - An inmate at Arkham Asylum who made a deal with Neron to bring him the Batman I's soul by poisoning everyone in the asylum and then forcing the Batman I to kill someone in it in order to get the antidote from him. The plan was thwarted when the Batman I poisoned Kryppen instead in order to make him give up the antidote's location. He is one of two people on this list who is not a supervillain; instead, he is an ordinary criminal.
- Lex Luthor (full name: Alexander Joseph "Lex" Luthor) - He was restored to full health and vitality after his cloned body fell victim to a "clone plague" that ultimately paralyzed him and made him a prisoner in his own body, unable to move or even blink, in exchange for his soul and giving "consultancy" to Neron. Became part of Neron's Inner Council prior to Underworld Unleashed #1 but, along with the Joker, double-crossed him and betrayed the other three Inner Council members.
- Major Disaster - He was given the magical ability to perceive probability and to locate weak points in objects and people, but was now only able to see the worst in life, in exchange for killing Aquaman.

- The Mist I (Kyle Nimbus) - He was cured of his senile dementia and his sanity was restored in exchange for destroying Opal City and harming the Shade I.Was one of two supervillains whose deal with Neron was made after the crossover event had ended (the other one was the Rag Doll I; see below).
- Mister Freeze - He was given natural cryokinetic powers (such as the ability to emit ice blasts from his hands, thus no longer needing his freeze gun) and was made able to survive in warmer temperatures without his cryogenic suit, although later he was reverted to his original subzero biology (how this happened is never revealed or shown) and built a new cryogenic suit and freeze gun as a result. He also briefly changed his name to Freeze before changing it back to Mister Freeze.
- The New Gods of Apokolips - Doctor Bedlam made an unknown offer designed to cause maximum death and chaos on New Apokolips and Granny Goodness and Virman Vundabar were given information about each other's plans (so as to perpetuate their civil war with each other); although Targa, a Hunger Dog who sought revenge for the murder of his father, refused to make a deal, even when Neron told him that he was destined to rule New Apokolips (it is possible, however, that he may have been lying, as usual) and, as a result, was actually surprised to find one righteous being on a world that was so steeped in evil that it was drowning. In exchange for all of this, Neron caused war and chaos on New Apokolips just for the sake of doing so.
- The Ocean Master - He was given a trident that granted him great mystical power, but it also caused him excruciating pain and horribly scarred his face whenever he was not actually holding it.
- The Psycho-Pirate II (Roger Hayden) - His sanity was restored and he was given enhanced power by being merged with his Medusa Mask (which was reduced to an eyepatch over his right eye, with the metal of the mask largely replacing one half of his brain), becoming a psychic vampire as a result who stayed sane by draining the remaining life and the sanity out of others after his mask had fed on their emotions.
- Purgatory - A man named Paul Christian who lost his legs and was given temporary legs by Green Lantern V. He was given permanent legs and a Green Lantern-type green flame power in exchange for killing Green Lantern V. Taken to Hell by Neron when he fails to do so after two attempts.
- The Rag Doll I (Peter Merkel Senior) - His youth and health were restored and he was given enhanced flexibility in exchange for destroying Opal City and harming the Shade I.Was one of two supervillains whose deal with Neron was made after the crossover event had ended (the other one was the Mist I; see above).
- The Rainbow Raider III (Roy G. Bivolo) - He apparently was going to accept the offer, but his chance to do so was taken from him by the Trickster I, who secretly stole his candle and replaced it with a rubber chicken. Later, Neron told the Trickster I in Hell that he considered the Rainbow Raider III to be so pathetic as a supervillain that he never would have even offered him a deal to begin with; indeed, even calling him a "paramecium" to the Trickster I's face.
- Satanus (has used the alias Colin Thornton) - He became one of Neron's lieutenants and was assigned to kill the Leymen of Primal Force publicly. When he failed to do so, he traded information on the whereabouts of his sister Blaze in exchange for him getting his soul back, but was killed by Neron after he betrayed him once his soul had been returned to him.
- The Shadow Thief I (Carl Sands) - He was given a more powerful shadow suit that possessed the ability to bring shadows to life and to change other people and objects into evil shadows that were under his control.
- Shrapnel - He was given enhanced power.
- Sledge - He was given enhanced strength.
- Louis "Louie" Snipe - The dead criminal informer who, when he was alive, helped kill Jim Corrigan I before he became the Spectre I. His spirit was briefly freed from Hell in exchange for becoming a host for the Spectre-Force instead of Corrigan I. The deal was never completed, however, and Snipe's spirit was trapped in a clay doll due to Corrigan I's intervention. He is one of two people on this list who is not a supervillain; instead, he is the spirit of an ordinary criminal.
- The Spellbinder III (Fay Moffit) a.k.a. Lady Spellbinder - She was given visually-based illusion powers that only worked if her eyes were uncovered. The deal was made after she killed her boyfriend, the Spellbinder I (Delbert Billings), who refused the offer. Neron then told her after the Spellbinder I's death that, when he made the deal, he was not actually offering it to the Spellbinder I at all (and, in fact, most likely would never have even offered it to him to begin with, since he obviously considered the Spellbinder I to be beneath him).
- Star Sapphire II (Caroline "Carol" Ferris) - Carol Ferris was offered a normal life without Star Sapphire II's spirit or her child (which was actually the child of Star Sapphire II and the Predator (both of whom were aspects (female and male, respectively) of her own personality). She was separated from both Star Sapphire II and the Predator, after which both of them were killed by Neron, who then took the child away in his arms.
- The Trickster I (Giovanni Giuseppe a.k.a. James Jesse) - He was not actually offered a deal, but Neron used him to watch his Inner Council, telling him that there would be time for a deal later. However, when he realized that no deal was going to be done for him after all and that Neron, a master player, had used him as a pawn, he became a key figure in the demon's defeat. Afterwards, realizing that he had just pulled off the biggest sting of his career-and that no one had even witnessed it-he decided to reform, because he definitely did not want to go to Hell where Neron could get a hold of him when he died.
- Tezcatlipoca II (Chama Sierra) - He was transformed into a human-jaguar hybrid.
- The Weather Wizard - He was promised that he would be one of the greatest supervillains that ever lived. Killed carrying out his task.

- The Magpie II (Margaret Pye)* - Unknown offer, although she was seen in a vision of Neron's making (which was shown to all of the supervillains assembled in Hell on a clear cliff wall) sitting on a huge pile of gold. Also shown in the same vision were the Atomic Skull II embracing Lois Joanne Lane in his arms (who, in his mind, was the woman he loved, "Zelda Wentworth" ) and Metallo III holding the cape of Superman.
- Mammoth* - Unknown offer.
- The Man-Bat* - Unknown offer; he appeared here in his human form of Robert Kirkland "Kirk" Langstrom.
- Mongul I - Neron killed him with his bare hands and took his soul after Mongul I refused to make a deal and attacked him, all because he thought that Neron had insulted him when he said that all of the supervillains assembled in Hell-including Mongul I-were all failures before Neron came into their lives.
- The Parasite II (Rudolph "Rudy" Jones)* - Unknown offer.
- The Pied Piper II (Hartley Rathaway; has used the aliases Thomas Peterson and Henry Darrow) - A reformed supervillain by this time; he had received a candle and kept it, but ultimately chose not to light it.

- The Ratcatcher* - Unknown offer.
- The Riddler - Unknown offer.

- The Shade I (Richard Swift) - He claimed to have reformed and that he was no longer a supervillain, even going so far as to tell Neron, in effect, to "Go peddle your wares elsewhere" , as he was already immortal, had great wealth that he had no need to increase and saw no way that his powers could be effectively enhanced. Neron, angered by the Shade I's rejection of the offer, swore that he would have revenge on him and ultimately got it much later by making deals with, and giving enhanced powers to, the Mist I and the Rag Doll I, in exchange for both of them-along with Doctor Phosphorus, with whom Neron had previously made a deal-destroying Opal City and harming the Shade I.

- Solomon Grundy* - Unknown offer.

- The Spellbinder I (Delbert Billings) - When he refused Neron's offer, he was killed by his girlfriend Fay Moffit who took the deal and became the Spellbinder III.
- Terra-Man II (Tobias "Toby" Manning)* - Unknown offer.
- Vandal Savage - He offered his soul willingly, without Neron even having to ask him if he wanted to make a deal-and, indeed, was the only supervillain in the crossover event to do so-but this time Neron himself refused Savage's offer, saying to him "Your soul-what's left of it-is black and tasteless." Because Savage's soul was exactly that-and was definitely not innocent-Neron did not want it at all. 
- The Ventriloquist I (Arnold Wesker) and Scarface* - Unknown offer.
- The White Dragon I (Daniel William Ducannon)* - Unknown offer.

Before Underworld Unleashed began
- Azrael #4 (May 1995) is a story that takes place several months before the crossover event started which is then continued-and finished-early on in the same event.
After Underworld Unleashed ended
- Aquaman (vol. 5) #18-20 (March–May 1996) reveals the Ocean Master's deal with Neron a few months into the following year after the crossover event had ended, but it is not labeled as a tie-in.
- Justice League Task Force #37 (August 1996), the last issue of the series, reveals that Triumph's previously rejected deal with Neron was accidentally (and unwittingly) accepted by Gypsy and the Ray II due to their misguided good intentions many months into the following year after the crossover event had ended, but it is not labeled as a tie-in.
- Wonder Woman (vol. 2) #115-119 (November 1996-March 1997) reveals the exact reason that the Cheetah III made her deal with Neron several months into the following year after the crossover event had ended, but it is not labeled as a tie-in.
- The Flash (vol. 2) #125-129 (May-September 1997) reveals the resurrection from the dead of-and the restoration of their souls to-the five Rogues who were previously killed by Neron's treachery two years after the crossover event had ended, but it is not labeled as a tie-in.
- Starman (vol. 2) #70-72 (October–December 2000) reveals that the Shade I's earlier rejection of Neron's offer in Showcase '95 #12 led to Neron making deals with, and giving enhanced powers to, the Mist I and the Rag Doll I much later in order to get revenge on the Shade I by harming him and destroying his adopted home of Opal City, but these deals were only seen in flashbacks within the story, which was published-and which occurred-several years after the crossover event had ended. Neron's revenge, however, was an important, albeit brief and off-panel, part of an elaborate scheme by Simon Culp, the Shade I's deadliest enemy, to get his own revenge on the Shade I as well.
- Teen Titans (vol. 3) #42 (February 2007) reveals Kid Devil's deal with Neron, which transformed him into Red Devil-and the consequences of the deal-in a story that was published-and that occurred-several years after the crossover event had ended.
- When the supervillains arrive in Hell, Neron's first words to them are "Please allow me to introduce myself" , the opening line of the Rolling Stones' song "Sympathy for the Devil". It is also the first thing he says to Paul Christian, who becomes Purgatory thanks to him.
- There are later repercussions from Neron's actions, mainly due to an unknown number of candles that still exist and have not been used. Among the superheroes, both Triumph and Kid Devil/Red Devil are most seriously affected, but these two events happen outside of the Underworld Unleashed crossover event.
- In 1996 DC Comics published Rogues Gallery, a one-shot issue that contained different artists' renditions of many of the supervillains that were in the crossover event. They are, in order:
- The Joker;
- Lex Luthor;
- Circe I;
- Abra Kadabra;
- The Trickster I;
- The Spellbinder III;
- The Riddler;
- Clayface III (Preston Payne);
- Mister Zsasz;
- Poison Ivy;
- Doctor Phosphorus;
- The Scarecrow;
- The Ventriloquist I and Scarface;
- Malcolm Merlyn the Dark Archer;
- Black Adam with Blaze;
- The Hellgrammite;
- The Dementor;
- Mongul I;
- Metallo III;
- Deadshot and Bolt;
- The Shadow Thief I;
- Chronos I;
- Granny Goodness;
- The Female Furies: Artemiz, Bernadeth, Lashina, Mad Harriet and Stompa;
- Killer Frost II;
- The Cheetah III;
The three-issue miniseries Underworld Unleashed, together with the one-shot issue Underworld Unleashed: Abyss-Hell's Sentinel #1, was collected as a trade paperback called Underworld Unleashed (DC Comics, March 1998, 158 pages, ISBN 1-56389-447-5).
- Writer Mark Waid said, in his afterword to the trade paperback reprint of the miniseries, that his original concept was to beef up a bunch of the old lame DC supervillains, but then he decided that they were actually pretty cool as they were, so he did not need to beef them up after all...at least not too much.-Underworld Unleashed trade paperback (DC Comics, March 1998 (ISBN 1-56389-447-5))
- Mark Waid was not impressed with the concept of or his own work on Underworld Unleashed. In his afterword to the trade paperback reprint of the miniseries he said of the storyline: "Knuckle-headed, well-intended creators ashamed of corny old characters have been, for most of a decade, dragging half-forgotten heroes and villains kicking and screaming into their own little hardware store of creativity. There, haunted by a guilty fear that these ancient superdoers aren't kewl enough for a generation of videogame-entranced readers, said knuckle-headed creators fool themselves into thinking they're doing them a good turn by bludgeoning all the innocent charm and colorful individuality out of them. I tried that once. Learned a lesson." -Underworld Unleashed trade paperback (DC Comics, March 1998 (ISBN 1-56389-447-5))
- Underworld Unleashed #1
- "The Trial of Superman!" , a crossover storyline in the Superman comics (November 1995-January 1996) that occurred at the same time as this crossover event
- Darkseid's supposed "death" occurred in Wonder Woman (vol. 2) #101-104 (September-December 1995). He would later return from the dead and reclaim the throne of Apokolips in The New Gods (vol. 4) #6-15 (March 1996-February 1997).
- Underworld Unleashed: Apokolips-Dark Uprising #1
- Superman (vol. 2) #107
- Underworld Unleashed #2
- Fate #13
- Fate #14
- Underworld Unleashed: Abyss-Hell's Sentinel #1
- Primal Force #13-14
- Green Lantern (vol. 3) #68-69,
- R.E.B.E.L.S. '95 #13-14
- Lobo (vol. 2) #22
- Note: the five Rogues would eventually be resurrected from the dead, regain their souls and would, like the other supervillains, no longer be in debt to Neron two years later in The Flash (vol. 2) #125-129 (May–September 1997). Mongul I, Purgatory, the Ice Man, the Spellbinder I and the Buggmeister would be the only permanent deaths in this crossover event.
- Superman: The Man of Tomorrow #3
- Underworld Unleashed #3
- Hawkman (vol. 3) #26-27
- The Spectre (vol. 3) #35-36
- Neron, however, in a cruel twist, revealed to Madame Xanadu that he had only made a deal with her just to prove that he could tempt those with "gray souls" as well as those who were evil.
- It is unclear as to whether or not it actually is Neron who is disguised as Kathy. Kathy changes into Neron when the Ray II kisses her, but later changes from Neron into Circe I and later appears again as Neron in Justice League Task Force #30 (avoiding the Ray II's question as to which one of them he really is). Circe I does not approach anyone else in the crossover event and she is shown in Hell with the other four members of the Inner Council throughout the event, which leads to the supposition that it is Neron all along.
- The Ray (vol. 2) #18-19
- Justice League Task Force #30
- When asked, Vril Dox II does not make it clear as to whether he sold his own soul or someone else's. Neron told Vandal Savage in The Ray (vol. 2) #18 that it was not possible to sell someone else's soul, but he may have been lying.
- Guy Gardner, Warrior #36-37
- The Batman I was wise to refuse Neron's offer, as Jason Todd later returned to life anyway in Batman Annual #25 (May 2006)
- Like the Batman I, the Flash III was also wise to refuse Neron's offer, as Barry Allen also later returned to life anyway in the DC Comics crossover event Final Crisis (2008).
- Superboy (vol. 3) #22
- Underworld Unleashed: Patterns of Fear #1
- Like the Batman I and the Flash III, the Oracle was also wise to refuse Neron's offer, as she would later regain her mobility and become Batgirl I again in Batgirl (vol. 4) #1-6 and #0 (November 2011-April 2012 and November 2012).
- Note: a continuity error. Although the Silver Swan II is among the supervillains assembled by Neron in Underworld Unleashed #1, she had become an active superhero four years before the crossover event started in the earlier DC Comics crossover event War of the Gods (1991).
- Ironically, Superboy would have risked nothing by accepting Neron's offer, as he did not actually have a soul with which to sell at the time. He did not develop a true "soul" until later, in Teen Titans Annual (vol. 3) #1 (April 2006).
- He did not accept, but his soul was accidentally (and unwittingly) sold to Neron by Gypsy and the Ray II many months into the following year after the crossover event ended in Justice League Task Force #37 (August 1996) when they unknowingly lit his candle. This resulted in Triumph getting his lost time back but still as a failure of a superhero, with the Justice League Task Force still the same as it had always been and Gypsy still alive even without him being in the League. It was because of this incident that Triumph later became evil.
- Note: technically not a real supervillain in the DC Universe at this point, more like a misguided nuisance
- Azrael #4 (May 1995)
- Azrael #10
- Guy Gardner, Warrior #36
- Superboy (vol. 3) #20
- Aquaman (vol. 6) #8-12 (September 2003-January 2004)

- Catwoman (vol. 2) #27
- The Adventures of Superman #530
- Robin (vol. 3) #23-24
- Underworld Unleashed: Batman-Devil's Asylum #1
- The Flash (vol. 2) #125-129 (May-September 1997)
- Aquaman (vol. 5) #14
- Note: although identified as an Underworld Unleashed tie-in on the cover, this issue has no real connection to the crossover event other than Major Disaster's appearance in it, which is not even an important part of the issue's main story.
- Steel (vol. 2) #21
- Note: this is a different deal than all of the others. Metallo III was approached directly by Neron and given a temporary new body and the candle to light, then a deal was struck later in Hell after he had lit the candle.
- Starman (vol. 2) #70-72 (October-December 2000)
- Batman #535
- Aquaman (vol. 5) #18-20 (March–May 1996)
- Manhunter (vol. 2) #11-12
- This is the first of three incidents in the crossover event that clearly show that even Neron has standards when it comes to making deals (for the other two, see References 69 and 74).
- Flash (vol. 2) #107
- The Spectre (vol. 3) #1 (December 1992)
- Detective Comics #691-692
- This is the third of three incidents in the crossover event that show that even Neron has standards when it comes to making deals (for the other two, see References 65 and 74).
- Extreme Justice #10-11
- The reason why Neron wanted the child was never revealed and the incident was never referred to or even mentioned again. Later, the DC Comics crossover event Infinite Crisis (2005) erased it from history.
- Green Arrow (vol. 2) #102-103
- Showcase '95 #12
- This is the second of three incidents in the crossover event that clearly show that even Neron has standards when it comes to making deals (for the other two, see References 65 and 69).
- Black Manta I's new body and powers are shown in this issue and Neron is alluded to as the cause (although his name is never mentioned and he is never seen or shown) in this tie-in (which is never identified as such) that occurs one month before the crossover event even starts.
- This is directly linked to, and finishes, an earlier story in Azrael #4 (May 1995), which occurred several months before the crossover event started. Azrael VI, who took the deal, also took several months to heal from his fall in this story (instead of being killed).
- Note: although not identified as an Underworld Unleashed tie-in on the cover, this issue leads into the next issue, which is identified as such.
- Note: although not identified as Underworld Unleashed tie-ins on the covers, this issue-and the one following it-both refer to what is happening in the crossover event.
- Note: not identified on the cover as connected to the crossover event, but completes the linked storyline of the previous issues and contains the introduction to Underworld Unleashed: Abyss-Hell's Sentinel #1.
- Note: this is the only story in this issue of Showcase '95, a yearly anthology series, that is actually a part of the crossover event. The issue is also not identified as a tie-in.
- Note: not identified as an Underworld Unleashed tie-in on the cover, but explains the second part of Vril Dox II's deal with Neron.
- Note: although identified as an Underworld Unleashed tie-in on the cover, this issue has no real connection to the crossover event other than one of Mister Freeze's two henchmen mentioning their boss's battle with Green Lantern V to the other one in passing (the two henchmen in this story are named Ice and Cube (a Caucasian woman and an African-American man, respectively), with each one having a tendency to finish a sentence spoken by the other in rhyme).
- Note: not identified as an Underworld Unleashed tie-in on the cover, but continues directly from the previous issue.
- Note: although not identified as an Underworld Unleashed tie-in on the cover, this issue has Luthor and the Joker thinking that they are in Metropolis, but later discovering that they are actually under Neron's spell and trapped in the snow globe that is shown at the end of Underworld Unleashed #2.
- Note: this issue of the crossover event-and the two following it-are also tie-ins to the crossover storyline "The Trial of Superman!" .
- Note: the entire scheme is chronicled in Starman (vol. 2) #61-73 (January 2000-January 2001) in a story arc called "Grand Guignol" .
- Note: the first song on the Rolling Stones' 7th U.K. and 9th U.S. studio album Beggars Banquet (1968)
