I'll kill you! I'll kill you to Death!
~ Superboy Prime to Monarch.

Superboy-Prime was one of the many variations of Superman in the DC universe but became unhinged following the destruction of his world and become one of the main villains from the Crisis on Infinite Earths storyline: he had even more power than current Superman and was comparable to the Silver Age Superman in scale of power - making him easily one of the most powerful supervillains in DC comics.


Crisis on Infinite Earths

The Crisis on Infinite Earths, a multiversal catastrophe int eh form of a wave of anti-matter sonsumed parallel dimensions by the Anti-Monitor. Superboy aided hundreds of worlds during the crisis, but was ultimately unable to prevent the destruction of the Earth from his own dimension. Superboy later took part in the battle against the Anti-Matter in the Antimatter Universe. After the defeat of the Anti-Matter, Superboy and the others escaped to a Paradise Dimension offered to them by Alexander Luthor, Jr.

Superboy-Prime secluded himself from others in the Paradise Dimension, opting to replay events from his life on Earth Prime using crystals. Over time, Superboy-Prime becomes frustrated, and attempts to reach out to Kal-L. Superboy-Prime was then persuaded by Alexander, who had come to believe that the Paradise Dimension was the reason for Lois Lane's failing health, to help him return to reality. When Superboy-Prime hesitated, Alexander showed him the negative aspects of the Post-Crisis Earth, including the deaths of his parents and girlfriend in a car accident.

Altering Reality

Superboy-Prime, infuriated, shattered the barrier of reality. This assault resulted in shifts in DC continuity, including; the resurrection of Jason Todd; the combining of Superman's origins; the Doom Patrol's rebooting as new characters; Donna Troy's mutliple origins; the various incarnations of Hawkman; the different incarnations of the League of Super-Heroes.

Countdown to Infinite Crisis

Infinite Crisis

Over time, as the four of them watched the history of the New Earth reality unfold, Superboy-Prime became frustrated and angry, homesick and wishing to return to the life he had. He consoled himself by watching images of his ninth birthday and grew horrified every time it would focus back on the Crisis. Alexander would notice that and decided to manipulate him to his needs. On two separate occasions, Superboy-Prime's anger got the best of him and he shattered the wall with his fists, the punch altering reality as it did. Upon deciding to join Alexander in his quest to bring about the "perfect" Earth, Alex empowered him with his Anti-Matter powers using it to break free. He was spotted by Blue Beetle, but Prime ignored him. In quick succession, Superboy-Prime obtained the Heart of Darkness diamond to be obtained by Jean Loring, altered the location of Thanagar, initiating the Rann-Thanagar War and attacking and capturing J'onn J'onzz, destroying the Watchtower.

When Alexander convinced Kal-L to leave their paradise reality, Prime was already with them, no one the wiser over what he had done. Soon after being freed, Prime was there to greet Power Girl after she was reunited with her cousin. However, when she discovered Alex's tower, Prime struck her down to be used for it. He then flew to Smallville, Kansas where he encountered the Superboy of this reality. He chastised the clone Superboy and accused him of being unworthy of the title of Superboy. The two fought one another and their epic battle raged across the state, eventually culminating in Keystone City. Members of the Doom Patrol, the Justice Society, and the Teen Titans arrived to lend a hand, but the power-mad Superboy-Prime thwarted even their efforts. He brutally attacked the heroes, killing several including Pantha, Bushido and Wildebeest. Jay Garrick, while Wally West, and Bart Allen grabbed Superboy-Prime and used their combined super-speed to propel him into the kinetic dimension of the Speed Force.

However, Superboy-Prime escaped from his imprisonment and built a battle-suit based on the Anti-Monitor's armor that constantly supplied his body with yellow sunlight. Superboy-Prime arrived at Alexander Luthor's tower to battle with Nightwing, Superboy, and Wonder Girl (Cassie Sandsmark). The heroes succeeded in releasing the metahumans powering the machine. After a brief fight, Conner grabbed Superboy-Prime and flew into the tower destroying it. However, Superboy-Prime would be unfazed by the attack, escaping as Conner was killed by the rubble.

Superboy-Prime then was seen at the Battle of Metropolis, killing both heroes and villains with ease. He continued his killing spree until he was met with resistance by Bart Allen in his grandfather's uniform. He was pulverized by Bart, but then left Earth to destroy Oa in an attempt to cause another Big Bang and reform the current universe hopefully closer to his original Earth-Prime reality. On the way to ignite this universal rebirth, Superboy-Prime killed 32 Green Lanterns. Then, while battling the Green Lantern Corps, Kal-L and Kal-El forced Superboy-Prime through Krypton's red sun to depower the vastly overpowered youth to levels where the elder Supermen could handle him directly. The three crash-landed on the Green Lantern planet Mogo, where they continued to fight. Kal-L's power levels were intact, but was still no match for even the power fading levels of Superboy-Prime, who was able to literally beat Kal-L to death with his bare fists and was able to fight against the New Earth adult Kal-El, whose own superpower levels had completely faded. But the time and effort Superboy-Prime used to attack Kal-L (whose strength and endurance was still superhuman) was enough to completely drain off Superboy-Prime's own power level to where the fully adult New Earth Superman was able to beat the still only teenage Superboy-Prime.

Superboy-Prime was then taken into the custody of the Green Lantern Corps. Too powerful to be placed in a regular Sciencell on Oa, the Guardians of the Universe imprisoned him inside a Sciencell near what is alternately described as a red sun or a Red Sun-Eater, constantly being guarded by fifty Green Lanterns. Members of the Corps were often assigned to "Prime Duty" as punishment. While in prison, Superboy-Prime carved a bloody "S" on his chest using his fingernail, saying that he had always found a way out (referring, presumably, to his escape from the Speed Force and his future prison).

Sinestro Corps

uperboy-Prime was freed, along with the Cyborg Superman, by a strike force of Sinestro Corps members who turned the red sun to yellow, presumably thereby restoring his powers. Superboy-Prime was brought to Qward, where he was made into a herald of the Anti-Monitor, along with Cyborg Superman, Sinestro and the Parallax-possessed Kyle Rayner.

Now calling himself Superman-Prime, Prime joined in the battle to attack most of the major heroes of Earth as part of the strike force of the Sinestro Corps. And again, due to the massive power difference between himself and the others, Prime was able to cut a path of destruction throughout the known universe, once again successfully defeating Kal-El of New Earth, but this time with Power Girl and Supergirl all at the same time with them charged up as well, ending the debate of who was the most powerful of the Supermen as well as many other high powered heroes in his role as the herald of the Anti-Monitor.

However, Prime showed that his main goals are to gain his revenge on the Anti-Monitor (who Superboy-Prime had accidentally revived during the Infinite Crisis) and somehow recover his lost universe, or at least the recognition as the so-called "real" Superman over weaker incarnations such as the adult Kal-El of New Earth.

Towards the end of the Sinestro Corps War, Prime was confronted by the Guardians of the Universe, who introduced the new Ion, the Daxamite Sodam Yat. Prime and Sodam Yat battle each other in a brutal and fierce fight. It was clear that Prime was clearly more powerful than Yat, though Yat refused to yield in any way. When the battle is taken inside a nuclear power plant (with its walls lined with lead), Ion was weakened by lead poisoning to the point that he can not even really fight back against Prime. Prime speared Ion with several lead rods, then beats him unconscious and left Yat for dead until the Guardians prevent him from actually killing Yat.

Later on, during the final battle between the Green Lantern Corps and the Sinestro Corps, the Anti-Monitor was severely injured when the Green Lanterns throw Warworld at him and the Cyborg Superman like a grenade. Prime takes this opportunity to turn on the Anti-Monitor and throws him into deep space. Prime is then attacked by both Corps and kills several members from both sides. Before any more lives can be lost, one of the Guardians uses himself as a living bomb and detonates himself to kill Prime. The explosion does not kill Prime, but merely transports him into the Multiverse. An unexpected result of the transport was that Prime's atoms were infused with a large portion of the Guardian's own energies that the Guardian thought would destroy Prime. The infusion of the Guardian's energy as part of his energy absorption and processing ability restructures his body to now appear as a fully adult man rather than his actual age of only 19.


Following the aftermath of the Sinestro Corps War, the now adult-looking Superman-Prime started a murderous rampage against all of his other dimensional counterparts and their supporters while searching for Earth-Prime. Superman-Prime traveled to Earth-15 and killing the Superman of that dimension and his wife and unborn child. After killing that world's Justice League, Superman-Prime destroyed Earth-15. Superman-Prime created a base of operations in the Source Wall, where captured and tortured Mr. Mxyzptlk and Annataz Arataz of Earth-3 to recreate Earth-Prime using their super-science/magic abilities or at least show him its location in the Multiverse. During his torture, Mxyzptlk reveals to Superman-Prime that his aging to adulthood was from him absorbing the cosmic Oan powers of the Guardian that blew himself up to kill him during the Sinestro Corps War. He also tells Superman-Prime that the cosmic energies will wear off very soon, and then he will turn back into a boy. After Mxyzptlk escaped, Prime was angered and gave up on the use of magic to achieve his goals.

After finding out about the so-called perfect universe which he thinks is his original source universe, Superman-Prime headed off to the Monitors' satellite headquarters, threatening the brutal Earth-8 Monitor Solomon to help him find this recreated Earth-Prime. Seeking to manipulate the infinite powered Superman-Prime to defeat the Monitors' forces against those of Monarch for the Monitors, Solomon sent Superman-Prime to Earth-51. As Solomon predetermined, the successfully manipulated Superman-Prime flew to the battlefield to challenge Monarch, in order to keep him from destroying Earth-51. Superman-Prime goes into a rage and attacks Monarch, with his cosmic powers seemingly beginning to dissipate. Prime then tears off the chestplate of Monarch's containment armor. The energies inside Monarch's armor are released, resulting in an explosion of quantum energy so massive, it destroys the entire contents of the Earth-51 universe.

Legion of 3 Worlds

Prime had been lost in the timestream following his final encounter with Monarch. The Time Trapper brought Superboy-Prime to the 31st century in his never ending scheme to destroy the Legion of Super-Heroes. He crashed into the 31st Century outside of Smallville. His stolen Oan energy at this point had faded, reverting him to his actual young age, as well as returning his power to their previous levels, which was what Mr. Mxyzptlk had foretold.

Upon arriving, he was encountered by a old farming couple, who thinks he's Superboy, which makes him extremely mad. He considers himself a man, not a boy, and killed the couple. When he flies to Smallville, he comes upon the Superman Museum, further fomenting his fury at how beloved Superman is in the future. He then became even more enraged when he sees the hall of villains, only to find out that he was not even considered a villain of Superman's, but no more then a nuisance and his statue was kept in storage. Furthermore, history retells that he was defeated by Conner Kent and Sodam Yat, totally contrary to what really happened. He proceeded to wreck the entire museum and kill whatever security or police officers he came across. The Museum tour guide (a holographic recreation of Jimmy Olsen) then tells Superboy-Prime of the Legion of Super-Villains.

When Superboy-Prime learned that the Legion of Super-Villains followed a code of evil, inspired by a dark being whose "name was never spoken," he got the idea to be the greatest villain Superman had ever faced. Superboy-Prime then went to the prison planet Takron-Galtos and freed the imprisoned Lightning Lord, Saturn Queen, and Cosmic King. When they saw Superboy-Prime, they immediately know him and hail him as the inspiration of the LSV's evil code, making him the dark being in question. He then burnt an S shield into the planet, that can be seen from space.

When the Legion of Super-Heroes learned of the prison break, they decided they need to bring Superman from the 21st Century. Superman and Brainiac 5 decide to bring in two other versions of the Legion to combat the Legion of Super-Villains. Superman believed the only way to stop the carnage is to try to redeem Superboy-Prime.

Superboy-Prime later makes his way to Sorcerer's World where he recruits Mordru to his Legion and kills the "last" active Green Lantern, Rond Vidar. Legion members Mon-El and Shadow Lass followed Vidar's ring back to Oa and find that Sodam Yat was still alive and had been monitoring the last Green Lanterns. They convinced him to battle Superboy-Prime once again. With Yat, Superman, and the Legions of two other dimensions as reinforcements, the Legion was able to turn around the battle with the combine forces of all their major villains in Metropolis.

Superboy-Prime burned a hole through Superman's hand and broke through Yat's ring construct just in time to be informed that there was something happening at Legion headquarters. At the headquarters, three Brainiac 5s, Lightning Lads, Lightning Lasses (one of whom is actually Light Lass), and XS, using a combination of living lightning and a Cosmic Treadmill, bring the young version of Bart Allen out of the Speed Force. Superboy-Prime is seemingly distraught at the thought of Bart's return, since he is the only person that was able to defeat him twice.

Not long after fighting Kid Flash, Element Lad turned the surrounding debris into Kryptonite, which actually causes harm to Superboy-Prime, but he then kills Element Lad by throwing a piece of Kryptonite right through him. Cosmic King then turns the Kryptonite in Superboy-Prime's body into yellow sunlight. When the LSH head to the North Pole to regroup, Superboy-Prime and the LSV follow them to the Fortress of Solitude. He attacked the three Brainiac 5's and cuts off Polar Boy's ice hand. Wildfire then used his powers to fuel a Kryptonian regeneration chrysalis inside the Fortress. From the chrysalis emerges a resurrected Conner Kent, a.k.a. Superboy, his corpse having been placed in the chrysalis by the LSH when they time-traveled to the 21st century as part of Brainiac 5's plan to recall Superboy-Prime's greatest enemies to the future to stop him. Superboy and Superboy-Prime clashed with the rest of the Legion joining in.

During the latest battle with the Time Trapper, Superman pulled off the Time Trapper's hood to reveal an aged Superboy-Prime as the Time Trapper's real identity. As the Legion continue their battles, the Time Trapper revealed that he had known the outcome of the battle, claiming that the Legion loses on this day. But, as the battle rages, Conner inflicts a wound on Superboy-Prime's body, burning a scar across his S-Shield-scarred chest and inflicting it upon the Time Trapper. Realizing that time, and thus his own body, is fluid, Superman, Saturn Girl, Cosmic Boy and Lightning Lad defeat the Time Trapper and drag him to the battlefield where the two Primes meet. The Time Trapper attempted to convince Prime in destroying the Legion, but Prime, whose arrogance means that he was unable to accept that he will become someone like the Time Trapper, attacked his older self, causing a time paradox that apparently wipes both of them from existence.

The paradox, however, flung Superboy-Prime back to a recreated version of Earth-Prime and reunited with his family and girlfriend. Instead of being greeted with open arms, Laurie Lemmon runs away, horrified at Superboy-Prime and his father confronts him over what he did. Prime learned that his parents and everyone else had read what he did in Infinite Crisis, the Sinestro Corps War, Countdown and Legion of 3 Worlds. His adoptive parents, now afraid of him, allowed Superboy-Prime to remain at their home, fearful of what he may do. Superboy-Prime was last shown with his eyes powering up in his parents basement, trolling the various DC Comics message boards, trying to prove his greatness and vowing that he will find someway to return to his former power and threat levels once again as he has shown he is committed to being the most powerful villain ever.

Blackest Night

In Adventure Comics (Vol. 2) #4, Superboy-Prime is seen again, still reading comics in his basement, trying to keep up with everything in the other worlds. When he learns of his fate at the end of this issue, he panics and demands his parents take him to the comic store, the Legion watching as he does. As they get there, Naomi reveals that she's afraid of him, but he brushes it off. In the comic store, he demands to know where Adventure Comics (vol. 2) #5 is, but the comic store cashier tells him that issue #4 just came out. He then tells him to look up possible spoilers on the Internet. As he does, Alexander Luthor appears, now a Black Lantern, killing the cashier and a customer. He confronts Superboy-Prime, wanting his heart. Superboy-Prime stops him briefly, knowing that this isn't the real Alexander Luthor. Luthor, in turn, grants Prime back his armor, returning him back to Superboy-Prime.

Superboy-Prime goes on the attack, but Alexander continues to taunt Prime, telling him that he's nothing more than a cosmic inside joke. Prime is then weakened and struck down by other forces. Looking up, Prime discovers Black Lantern versions of those he killed, including Element Lad, Charaxas and Bushido, with Alexander telling Prime that he will die in the next issue.

The next issue, Superboy-Prime is seen having taken the battle from his hometown to Manhattan, where he crashes through the DC Comics headquarters, where he decides that, if he's going to die, he's taking the writers and plotters who made his life that way. Before he can, though, Black Lantern Alexander Luthor arrives and pulls Prime away, taking him back to his room. There, Alex taunts him over losing Laurie as the other Black Lanterns beat him down and tear away his armor. Realizing he can't win, he catches a Black Lantern Ring and puts it on, the ring commanding him to die.

As he becomes Black Lantern Superboy-Prime (realizing Alex's cryptic statement at the end of the previous issue), the ring cycles through the Emotional Spectrum: willpower due to his deluded demand for respect, compassion for regretting what he did to Laurie, avarice for wanting everyone to love him, fear of those he once admired, and stopping at rage for hating himself for what had become, transforming into Red Lantern Superboy-Prime. He goes into the offensive, attacking Alex over his attacks. At the very end, the ring asks him who does he love. He calls out that he loves Laurie, transforming him into the Star Sapphire Superboy-Prime with the last of his strength. As he passes out, the Black Lantern Ring shatters, unleashing the white light and eradicating the Black Lanterns.

In the end, he admits that he hates what he has become and all he wants now is just his happy ending. As if someone was listening, Laurie appears, her arm in a sling (meaning that the horrible thing Superboy-Prime did to her lead to her having broken her arm). She tells him that they (possibly the writers) have heard his pleas and sent her to tell him that they're going to start leaving him alone. Unbeknownst to him, she's also wearing a Black Lantern Ring, but this one sparkling with hope, the last of the emotions that Prime wasn't asked about.

Legion of Doom

During a battle with the Teen Titans, a young villain named Headcase opens up a wormhole that accidentally transports Superboy-Prime back to New Earth (in full armor, even though his armor was destroyed in his last appearance). Enraged by his separation from Laurie, Superboy-Prime vows to destroy the Titans and find a way to return home. He subsequently assembles a cadre of young super-villains consisting of Headcase, Zookeeper, Indigo, Sungirl, Persuader (Elise Kimble) and a new Inertia, each of whom have a personal grudge against the Titans.

Superboy-Prime also brings three clones of Superboy (formed from the remains of Match), and he uses them to assist in the attack on the Titans. Superboy-Prime and his team attempt to destroy Titans Tower, but are met by a large group of former Titans. After Superboy-Prime is defeated by the combined might of the surviving Titans, Superboy and Supergirl imprison him within the Source Wall.


Originally destined to be the greatest superhero and the world's chosen champion in the fight against evil, Superboy-Prime, left scarred by the traumatic events he witnessed has become a brutal killing machine. Years of isolation in the paradise dimension while endlessly viewing the events of a life he could no longer have put severe stress on his already fragile mind. During Infinite Crisis when the turning point came and he accidentally killed several heroes his mind finally snapped and he retreated into denial of the horrific nature of his actions. After being further imprisoned by the Flashes and spending three more relative years imprisoned again, Prime has buried any remorse or compassion under an insane belief that since he is a Superman, everything he does is right and views any other reality apart from his own as an imperfect duplicate of his world. All of this has left Prime in a psychotic state of mind unable to distinguish the morality of his own actions and the ability to commit even the most heinous of deeds with no guilt at all. Hellbent on nothing but killing numerous superheroes while also leaving an endless wave of utter destruction in his wake and as such, is one of the most dangerous villains in the universe.


Superboy-Prime has had a collection of powers over time, being one of the many alternate Supermen of DC comics he possesses standard Kryptonian powers but was able to amplify them via power-armor and other devices: over the course of the Crisis Superboy-Prime became more and more powerful, at the peak of his power he had absolute control over time to the point he could create pocket universes.

Also due to Superboy-Prime being from another universe he was immune to most of Superman's weaknesses, such as magic and kryptonite - his power-suit was also designed to constantly feed him yellow sun radiation and keep him at peak power even when exposed to red sun radiation.
