Quote1 Bizarre. The more dupes I created, the more it "thinned out" Locke's control, until I finally broke free. And all these Hydra agents dead...because of me. Frightening. But the most frightening thing of that I don't feel anything. No regret. no horror. No elation. Just... empty. And that's bad. Very... very... bad. Quote2
Multiple Man[src]



Jamie Madrox's mutant ability was apparent as early as his birth. He created his first duplicate when the doctor smacked him on the bottom.[13] Two weeks later, Jamie's father Daniel resigned from the Los Alamos Nuclear Research Center and moved his family to an intentionally isolated farm in Lawrenceville, Kansas[1] at the suggestion of Professor Charles Xavier. Later, Damian Tryp, of Singularity Investigations, made his own offer to look after Jamie, claiming that Jamie was not in fact a mutant, but a "changeling," a predecessor to mutants, who manifest their powers at birth. Jamie's parents, however, refused to give Jamie to Tryp.[13] From a young age, Madrox was given a special suit to wear that would neutralize his mutant power, but, before this could be explained to him, a freak tornado killed his parents when he was 15,[1] later revealed to have been caused by Tryp, who had also manipulated Jamie's memories to make him forget his part in the accident.[18]

Madrox spent the next six years alone caring for his parents' farm. When he was 21, malfunctioning control elements in the suit caused a power surge that released his inhibited power and caused the suit to begin absorbing ambient electrical energy. Confused, frightened, and driven mad by isolation, Madrox felt himself drawn to New York City. There, he clashed with the Fantastic Four until Xavier arrived to defuse the situation.[1] With the help of Xavier and Reed Richards, Madrox's suit was repaired and he accompanied Xavier back to his mansion in Westchester County. There, Madrox's temporary madness was cured and, after learning to cope with his powers, he was invited to join the X-Men. He declined, and instead accompanied Xavier to Muir Island where he became a laboratory assistant to mutant researcher Doctor Moira MacTaggert.[citation needed]

Muir Island[]

Madrox's ability proved invaluable to MacTaggert, and he quickly became a regular fixture on Muir. Unfortunately, Madrox also found himself battling against threats such as the alien Eric the Red and the reality-altering mutant Proteus, who possessed one of Madrox's duplicates in order to escape confinement on Muir. Proteus's possession instantly killed the duplicate, and for the first time Madrox felt the severe psychic backlash caused by the death of one of his duplicates. After Proteus was defeated, Madrox again declined to join the X-Men, preferring to remain on Muir Island with Moira and her lover, the X-Man Banshee.[19] Soon after, Banshee's daughter Siryn came to live on Muir[20] and she developed a romantic relationship with one of his dupes, unaware he wasn't the original.[21]

Eventually, another one of Madrox's duplicates sought to remain apart from the original and live his own life. To this end, he drugged the original Madrox[22] and joined Moira and Siryn on a trip to the U.S. to search for Sunspot and Warlock, two missing members of the New Mutants. There, they met the young mutant group known as the Fallen Angels. Unable to convince them to come back home, Jamie and Siryn joined the Fallen Angels as well.[23]

With the Angels, they met Boom-Boom, visited the Valley of the Flame, on Dinosaur World, and traveled to Coconut Grove, the home planet of their teammate Ariel. The inhabitants of the Coconut Grove captured the Fallen Angels, intending to use them as experiments to continue their evolution, but the Angels worked together to defeat them and return home. In the end, Sunspot and Warlock decided to return to the New Mutants, but Siryn and Madrox chose to remain with the Angels for a while longer, instead of going home to Muir Island.[24]


Later, the original Madrox was possessed by the psionic entity the Shadow King during the villain's takeover of Muir; after his defeat, Madrox joined the government-sponsored X-Factor team.[25] Unknown to Madrox, the duplicate that had joined the Fallen Angels years before had since found a place in the Nasty Boys, a team of super-powered mercenaries employed by geneticist Mister Sinister. With the help of Senator Steven Shaffran, a mutant with the ability to turn other mutants' powers and fears against them, the duplicate convinced X-Factor that he was the original. Madrox merged with the duplicate, but it was a ruse; he "disassembled" the duplicate from the inside and remained the dominant personality in order to expose Shaffran and stop Sinister.[26]

X-Factor Vol 1 146

Later, when most of the team were busy with another assignment, Madrox and his teammate Quicksilver were sent to investigate a murder case in Maine in which the prime suspect was a young mutant named Rhapsody, who had been fired from her music teaching job after turning blue and first manifesting her ability to entrance others with music. The man responsible for terminating her employment was found dead two days later, with Rhapsody apprehended at the scene of the crime. Exposed to the effects of Rhapsody's power, Madrox became convinced of her innocence and was set to break her out of prison when the truth was revealed. Rhapsody had used her power on the victim in an effort to make him see the error of his decision to fire her, only to accidentally cause his death.[27]

Following an attempted assassination of Xavier supposedly by the mutant soldier from the future, Cable, X-Factor and the X-Men teamed up to capture Cable's team of young mutants, X-Force. Among X-Force's number was Siryn, who confronted Madrox over their past relationship. Madrox revealed to Siryn that although he retained all the memories of her relationship with his renegade duplicate, he possessed none of the related emotional attachment.[21]

Among his X-Factor teammates, Madrox formed a close bond with Strong Guy. The pair shared an odd sense of humor and often joked around much to team leader Havok's chagrin. A psychiatric analysis by Doctor Leonard Samson ultimately revealed the reason for Madrox's humorous attitude. His living alone for many years as a child created an almost pathological need for attention to ensure he would never be alone again, and he was willing to do virtually anything - whether it be telling jokes, playing gags, or creative use of dupes - to get people to notice him.[28]

During a subsequent mission with X-Factor to the island nation of Genosha, one of Madrox's duplicates contracted the deadly Legacy Virus; when reabsorbed, it was believed Madrox himself was infected. The mutant prophetess Haven offered to cure Madrox of the Virus, but the attempt failed and he seemingly died. [29] However, Madrox unconsciously stayed split into separate bodies, ensuring that the Virus would be contained in one body and not duplicate into the others. When the infected body died, the shock of its death caused Madrox to lose his memory. Later, X-Factor was sent on a mission to apprehend a mysterious figure that was revealed to be Madrox, alive and well with his memory restored. Madrox had been recruited by elements of the U.S. government that wanted to turn him into the ultimate secret agent, training him to become a one-man army. Madrox ultimately rejoined X-Factor until the team's disbanding after the apparent death of its leader, Havok. He then returned to Muir Island where he was reunited with both Moira and his X-Factor teammate Wolfsbane. Madrox subsequently worked in Genosha at the behest of Professor X to monitor the situation there after the rise to power of mutant activist Magneto.[30]


Madrox was then recruited by Banshee into the paramilitary X-Corps organization for which Madrox created duplicates to function as support staff performing duties ranging from communications monitoring to gunship pilots.[31] Following the restructuring of the X-Corps into the X-Corporation global mutant search and rescue organization, Madrox worked with the group's European branch for a time until a pitched battle against the living bacterial consciousness known as Weapon XII cost the life of his teammate Darkstar.[32]

X-Factor Investigations[]

Madrox subsequently quit and struck out on his own. For a long time, Madrox had been unable to decide what to do with his life, and as a solution, had sent out a large number of dupes for the past few years to each live separate lives and then return to him so that he could absorb their knowledge and experiences. Madrox also established XXX Investigators in Mutant Town hiring former X-Factor teammates Strong Guy and Wolfsbane as a bodyguard and assistant respectively. His first case was to investigate the murder of one of his duplicates by an assassin named Clay, who also possessed the ability to create duplicates of himself, which led Madrox to Chicago and Sheila DeSoto, fiancée of multi-millionaire industrialist Edward Vance. Unbeknownst to Madrox, who had become romantically involved with Sheila, she was the one who had hired Clay to prevent Madrox from interfering in her plans to take control of the Chicago crime syndicate. Sheila was ultimately killed after she was revealed to be a self-styled highly evolved mutant. The firm was renamed X-Factor Investigations after the government-sponsored X-Factor mutant superhero group that the three founders had previously served on.[33]


Following M-Day, Madrox's new-found wealth (from winning a Who Wants to be a Millionaire-style game show) allowed him to recruit two of his former colleagues of the Paris branch of the now-defunct X-Corporation: Siryn and Generation X's Monet. Moreover, the team was then reinforced with the arrival of a depowered Rictor and the mysterious, young Layla Miller.[34]

At this point, Jamie's powers had become defective[35] and he could no longer distinguish his memories from that of his dupes,[36][7] like he used to.[21] In addition to that, whenever one of his new dupes died, he would inherit his memories, something that was impossible before.[35]

X-Factor Vol 3 1 Textless

X-Factor Investigations after M-Day

Siryn, as part of her duties for X-Factor Investigations, investigated the murder of the woman who died in Jack Vaughn's penthouse under suspicious circumstances. Jack Vaughn (a movie star) claimed that the woman had been killed by her sister, Gloria Santiago, who was upset about the relationship between the two. Rival agency Singularity Investigations represented Jack Vaughn, with Tryp, Jr. (secretly a young Damien Tryp) as the defense counsel, while X-Factor Investigations tried to help Gloria. After Monet established a mental bond with Gloria to assess the truth, she managed to incriminate Vaughn, while Layla thwarted SI’s assassination attempt on Rictor. Tryp, Jr. was so infuriated by this that he badly beat Siryn and left her for dead (having shot her in the neck with a dart that prevented her from using her powers).[37]

Madrox and Strong Guy gave Tryp a very public warning as Tryp was jogging in Central Park. They told Tryp that they knew that it was him who hurt Siryn, and while they would not hurt him in broad daylight, he should watch his back.[38] With this, Tryp, Junior and Tryp, Senior made Madrox an offer to merge X-Factor with their firm, making Madrox laughed in response.[39]

After the meeting, Madrox started suspecting Singularity Investigations wasn't responsible for the decimation, as he'd previously thought, so he asked Siryn to find out more about it from the heroes who might have been involved (by using her modulated voice to make them more suggestible). She learned from Spider-Man, and later from Quiksilver, that the X-Men (who had denied any involvement) were, in fact, central to the ending of the House of M and the subsequent Decimation. After a confrontation, Madrox decided X-Factor would take a public stance in defiance of the Superhuman Registration Act and the X-Men decided not to interfere with Quicksilver as long as he stayed in Mutant Town.[40]

X-Factor Vol 3 13 Textless

X-Factor Investigations, with Layla on the team

A former Singularity employee went to X-Factor Investigations and revealed that Tryp was attempting to create a modern version of the Legacy Virus. Strong Guy was sent to drive the man to safety but once they were alone, Strong Guy killed him and called Tryp to report it. Guido tried to tell the team that the man had vanished on him but Wolfsbane smelled his blood on Guido's hands and a psychic scan by Monet revealed the truth. It seemed Tryp had placed a hypnotic suggestion in Strong Guy’s head to turn him into a sleeper agent. After breaking into Singularity Investigations, the elder Tryp confronted the team and revealed that all of Singularity Investigations' efforts to create the new virus had been made to prevent a possible future in which X-Factor managed to undo the Decimation and ended up causing humanity's destruction at the hands of re-powered mutants in a bloody conflict.[41]

As the team was fleeing the building, one of Madrox's dupes blew up the whole thing, apparently killing Tryp, Junior and Tryp, Senior. After this, the elder Damian Tryp, who had managed to survive the explosion, revealed to Layla that her very existence had foiled his plans, but things would be different now that he knew of her existence.[18]

One night, Madrox got drunk, and a dupe he described as his libido incarnate slept with Siryn and Monet, but, back then, Jamie didn't know if he had slept with one of the women or if the dupe had slept with the two. Regardless, Jamie kept it going with the both of them, afraid of revealing that he was double-timing them. After the confrontation with Singularity Investigations, the members of X-Factor met with Doc Samson, who encouraged Jamie to confess the truth to Monet and Siryn. They did not take it well.[36][7][42]

John Maddox (Earth-616) from X-Factor Vol 3 16 001

Reverend John Maddox

After Madrox's experience with a duplicate who was an agent of S.H.I.E.L.D., whose existence he had forgotten about, Madrox decided to go on a quest to gather his lost dupes.[7] One of the first dupes he encountered was John Maddox, who had become a priest and built his own family. He was very determined to keep his individuality and even threatened to shoot Madrox to achieve this goal. However, Jamie won a resulting contest of wills, and John finally submitted to absorption. In the end, Jamie realized the importance of what his dupe had accomplished and decided to let him remain free and live with his family.[4]

Jamie met at least one other dupe before returning home. This one had become "the world's greatest detective" and had discovered secrets so important and disturbing that he would rather die than let Jamie live with that knowledge. After killing a corrupt cop in the middle of the street, he was shot by the whole squad accompanying him. Unlike the recently created dupes, this dupe perished with no memories being transferred to Jamie.[35]

Meanwhile, Siryn and Monet had bonded in France and rescued an ex-mutant named Nicole from a riot.[4] When Jamie got home, a group of ex-mutants believing the government had depowered mutants was now operating in Mutant Town. After Quicksilver restored most of the mutants' powers using his Terrigen Crystals, Jamie led a battalion of dupes to face the group, but, in the end, it was their unstable powers that led to their defeat, resulting in the death of one of them and others' retreat. Quicksilver was dealt with by Rictor, who turned against him after he threatened Layla.[43]

X-Factor tangled with The Isolationist, a powerful telepath (among other things), who convinced Madrox, Cyclops, and Beast to organize a "Million Mutant March" political rally on Washington, D.C. to get mutants declared an endangered species by the U.S. government. However, Layla Miller told Madrox that Nicole was one of Huber's agents and had tried to kill her, leading to a confrontation between Huber and the team, which resulted in Madrox, Guido and Rahne being teleported to a frozen wasteland. Luckily, Rictor and Monet fought Huber soon after and forced him to retreat, rescuing the team in the process.[44]

Dupe and Layla going to the future

Madrox, Rictor, and an accompanying Layla Miller were alerted to the Xavier Mansion by Emma Frost after the first mutant birth since M-Day.[45] Madrox and Layla were sent to Forge's headquarters to send two dupes into different alternate realities. Layla jumped in with one of the dupes at the last minute, claiming she had a part to play in their mission. Unfortunately, Forge informed Madrox that there was no way to retrieve Layla and his dupes, who received instructions to kill themselves once they received the information they needed to get reabsorbed into Madrox Prime.[46] Layla and the Madrox-dupe landed in Bishop's future, where they were captured and branded as mutants.[47][48] Layla killed Madrox's dupe, which strangely led to Madrox Prime gaining the same tattoo the dupe had gotten.[49]

The end of Mutant Town[]

After a confrontation with Jamie about her leaving, Rahne revealed that she had seen herself murder Jamie and Layla Madrox on their wedding night, and not wanting to kill Layla upon her return from the dystopian future, left the team. Rictor, who'd only been left a letter by Rahne, decided to quit as well, but was kidnapped by the X-Men villain Arcade before he had the chance. In addition to that, Arcade also spread several bombs and placed a disintegration grid surrounding Mutant Town, preventing everyone from getting in or out. In the end, X-Factor managed to shut the grid down, but they were unable to save Mutant Town, as it was destroyed by Arcade's bombs.[50]

Theresa Cassidy (Earth-616) and James Madrox (Earth-616) from X-Factor Vol 3 32 001

In the aftermath of the event, Val Cooper met with the team and tried to recruit them, giving them 24 hours to think about it. Around this time, Madrox also began hallucinating a figure of Layla Miller, who would help him realize things that his subconscious already knew. Thanks to this, Madrox realized what Siryn had been trying to tell him for the last couple of days: she was pregnant with his child. After talking to her about it, the two embraced and discussed the future of the baby and Val Cooper's offer. The whole team then voted, but decided to escape and relocate to Detroit, Michigan.[51]

Time in Detroit[]

Secretly, Val reached Jamie again, and X-Factor started taking cases for the government as well.[52][53] Theresa found out shortly before giving birth, but she decided to forgive him and proposed to Jamie, who accepted without second thought. When she gave birth, she finally acknowledged that her father was dead decided to name her son Sean, in his honor. As Jamie held his son for the first time, tragedy struck and he absorbed Sean, leaving Theresa in a deep state of sorrow.[54]

James Madrox (Earth-616) and Sean Madrox (Earth-616) from X-Factor Vol 3 39 001

Jamie's worst nightmare

Jamie also didn't deal well with the situation well and left X-Factor Investigations. He walked all the way to Vermont to speak with Pastor John Maddox. After having one final conversation with his dupe, telling him to live for the both of them, he knocked him out and pointed a gun to his own head, planning to end it all right there. An instant before he pulled the trigger, however, an older Layla Miller arrived to stop him.[42]

Convinced by Layla, Jamie was transported 80 years into the future. In that time, mutants had risen up against Sentinels and human oppressors and formed the Summers Rebellion, led by Ruby Summers, the daughter of Cyclops and Emma Frost. After Jamie got reacquainted with Layla, Cyclops tasked them to find out why some mutants were winking out of existence.[55] The group visited a senile Doctor Doom, who revealed he'd met Layla before and was ready to help solve the mystery.[56]

X-Factor Vol 3 41 Textless

Summers Rebellion

However, Doom betrayed the team and brought Cortex to this reality to kill all the mutants in the rebellion.[57] Cortex was the other dupe who had been sent to the future by Forge and, after getting trapped in a time vortex and experiencing millennia pass, had grown resentful towards Jamie. The initial mystery was also revealed to have been Cortex's attempts to kill the rebellious mutants' ancestors to prevent their births.[58]

The Summer's Rebellion was attacked by Cortex and the sudden arrival of a Sentinel army. Trevor Fitzroy was killed, but Layla was forced to resurrect him, inevitably turning him into the villain he was destined to be, since she could bring people back, but not their souls. In then, Madrox and Layla were sent back to the present. While Madrox ended up with X-Factor, Layla was nowhere to be seen.[58]

Back in New York[]

Jamie took Guido and the two left to open a new branch of X-Factor in New York, allowing Terry to stay in charge in Detroit. This didn't last long though and soon she disbanded X-Factor, forcing the rest of the team to join Jamie and Guido in New York. One of their first mission brought X-Factor to Latveria, where they were reunited with Layla, who had been staying with Doctor Doom since her return from the future. This reunion was cut short after Layla intentionally distracted Shatterstar while he was opening one of his portals to behead an evil version of Doom, leaving the two behind in Latveria.[59]

X-Factor Vol 1 224

Reunited in New York

After Layla and Shatterstar saved Theresa (now going by Banshee) from Trask's MRD, the trio joined X-Factor at New York. With X-Factor now at full force, they defeated Trask, and Terry and Madrox finally reconciled.[60]

While protecting J. Jonah Jameson, then-mayor of New York, Strong Guy was killed, but Layla brought him back to life using her powers.[61] This changed the future Layla knew, and, when the demon Bloodbath attacked X-Factor, Jamie was unexpectedly killed, causing Layla great emotional distress.[62][63]

They Keep Killing Madrox[]

Jamie, however, did not simply die. He appeared in an alternate reality by the corpses of Layla and himself on their wedding night, and confronted Vanora, who Layla had paid to kill them. Jamie died again (this time hit by a car) and found himself in a reality a Deathlok Captain America. After dying yet again, he found himself the apprentice of Doctor Strange, who had just died at the hands of Dormammu. There, the spirit of Doc Strange was able to help him defeat Dormammu and send Jamie back to his reality, but complications drew Vanora, Deathlok, and Dormammu with him.[64]

Jamie's body suddenly came back to life in the icebox Layla had kept it in. Overjoyed at his revival, Layla immediately took her clothes off and took their relationship to the next level. Afterwards, Jamie regretted letting that happen and was surprised to learn that Havok and Polaris had taken over X-Factor Investigations.[65] For a while, Jamie and Alex both acted as leaders of X-Factor, but eventually Alex realized that had very different leadership styles and left the team.[66]

Layla Miller (Earth-616) and James Madrox (Earth-616) from X-Factor Vol 1 247 001


After Terry became the new Morrigan and left the team, Jamie asked Layla to marry him on a whim[66] and the two traveled to L.A. to make it official.[67]

Upon their return, they had to face the Hell on Earth War, during which Jamie was captured by Mephisto and turned into a demon.[68] Initially, he didn't appear to have any consciousness or memory of who he was, but after Layla told him she was pregnant with his child, he prayed to Terry, and she cured him of his condition with her new Morrigan powers.[69]

Retirement and Death[]

With his curse lifted, Jamie retired to his family farm with Layla and sold the rights of the X-Factor name to Harrison Snow.[70]

James Madrox (Earth-616) from Death of X Vol 1 1

Sometime later, Jamie went to Muir Island to investigate what effect the Terrigen Mists had on mutants. He discovered that the Terrigen Mists were toxic to mutants, but by then, he began to suffer from the lethal effects of the Mists. He sent out a distress call, which was received by Cyclops' X-Men. The team found Jamie dying among a group of dead or dying dupes. With his last breath, Jamie told Cyclops what he had discovered about the Mists.[14]

Jamie along with his dupes and the research team he worked alongside were buried on Muir Island.[71]

After the death of the original Madrox, one dupe survived inside a bunker who temporarily became the "Madrox Prime" until another dupe took his place[72]. This dupe remained the Madrox Prime until his own death.[73]

Dawn of X[]

Jamie was presumably resurrected by the Five in Krakoa and joined the new mutant nation. He was interviewed by Marvel Girl following an ambush of Xavier’s Pharmaceuticals Distribution Site where some of his dupes were in critical condition and reabsorbed for recollecting what had happened.[15] While on Krakoa, Jamie was put in charge of the research labs that produce the Krakoan drugs M, I, and L. It was while fulfilling this role that he was recruited by his old teammate Monet to join X-Corp's Board of Directors.[5]

After his return, Jamie no longer possessed the M-shaped tattoo on his face.[74]

During the launch of the Ionospheric Bandwidth Generator, his wife, Layla asked Jamie to come home to witness his son Davey's first steps. Madrox sent a dupe, planning to reabsorb him and gain his memories, but the dupe died and the memories of Davey's first steps were lost.[75]

As well as working as a researcher for X-Corp, Madrox' ability to duplicate himself also encouraged the nation of Krakoa to call on him to work as a waiter and server at the annual Hellfire Galas. At the third and final of these, the party was cut short in a brutal attack by anti-Mutant organization Orchis. Multiple "Jamies" were killed during the attack, their bodies shattered by Nimrod.[76]


Although his dupes were present as servers and were murdered by Nimrod, Madrox Prime was taking "personal time" during the Mutant Massacre at the Hellfire Gala. To help operate X-Corps Island, Mirage recruited him to X-Corps.[77]

Madrox is a Changeling, the genetic predecessors of mutants whose powers manifest at birth instead of during puberty. Madrox's powers include:

James Madrox (Earth-616) from X-Men Messiah Complex Vol 1 1 001

The Multiple Man in action

  • Kinetic Duplication: Jamie Madrox creates identical physical duplicates of himself upon physical impact. This process is spontaneous and cannot be prevented by Madrox. Although he can create multiple duplicates, and the duplicates themselves can also replicate, each is only able to create one duplicate at a time; he used to have an upper limit of 40 dupes, but that is no longer the case.[78] The duplicates think, feel, and act independently, and each tends to manifest one aspect of Madrox's personality.[79]
    • Duplication Experience Transference: When Madrox merges back, he retains memories, knowledge, and experiences of the dupe. At first, his absorbed memories would feel like "watching TV",[21] however, at some point Jamie's powers became defective[35] and he could no longer distinguish his memories from that of his dupes.[36][7] In addition to that, whenever one of his new dupes died, he would immediately inherit his memories without having to absorb them.[35] After coming back to life, it appears he's lost this ability.[5][75]
    • Duplication Healing: Absorbing an injured dupe formerly resulted in the prime Madrox suffering an injury half as severe, but he currently suffers no injury whatsoever.[78]

Notable Duplicates[]

  • Proteus possessed dupe - Proteus once possessed a Madrox duplicate in order to escape confinement on Muir Island, killing him at the instant he possessed him. It was the first dupe to die, causing a trauma to Jamie.
  • Fallen Angels & Nasty Boys dupe - one of Madrox's evil dupes joined the Nasty Boys. The first to show real independence, drugging Jamie to go to USA with Moira and join the Fallen Angels. Later came back and impersonated the original, absorbing him for a short time, unknowing it was on the real Madrox authorization.
  • Independent Mutated Madroxes - During his trip to the U.S., the Fallen Angels dupe created a duplicate who wanted to live for himself. His source paradoxically stated it was the first dupe who denied to re-merge. His difference was shown by incomplete independence on his source duplicate (or it was the fact that this was not the original source) and a Mini-Cerebro analysis who designed him as different from his source.
  • Chicago dupe - This dupe lived in Chicago and married Shelia DeSoto, crime boss Edward Vance's fiancée. He was later assassinated by Clay.[80]
  • Shaolin Monk dupe - This dupe was sent by Madrox Prime to the Shaolin Monastery to study meditation. He later returned for absorption.[80]
  • Homosexual dupe(s) - Several dupes have demonstrated or discussed some homosexual feelings and/or tendencies.[81][82][7][83][84]
  • EMT dupe - One of Madrox's many dupes was trained as a paramedic.
  • Anatomy class dupe - One of Madrox's many dupes audited an anatomy class for six months.[82]
  • Russian dupe - One of Madrox's many dupes was sent to live in Moscow for a year and a half to learn Russian. He complained a lot that he wasn't in Hawaii.[82]
  • The X-Factor dupe - This dupe once tried to kill Rictor[85] and later reemerged in time to blow up Singularity Investigations. He alone seemed to remember his first encounter with Damian Tryp.[18]
  • James Madrox Esq. - One of Madrox's many dupes went to law school and passed the New York Bar exam.[86]
  • Agent Madrox - Agent Madrox was a "co-original" of Madrox sent out to study espionage. He made contact with Val Cooper, who set him up with her connections at S.H.I.E.L.D..[9]
  • "Heff" dupe - After celebrating and heavy drinking, Madrox bumped into a wall and created a dupe that later sleeps with Siryn and Monet (or both).[13] Jamie described this dupes as his "libido unleashed".[7] The result of the union was the conception of Sean Madrox.
  • Father John Maddox - John was originally created to learn from the world,[87] and went to study religion. While studying he changed his name to John Maddox, married, started a family, and became an Episcopal pastor. Jamie decided not to absorb him because of his family and life.[4]
  • "World's Greatest Detective" dupe - After going to Detroit and Chicago to study investigation, criminal justice, and police work, this dupe became disillusioned with society and the justice system. When Madrox came to reabsorb him, he claimed to have become the World's Greatest Detective. He also claimed to know why Madrox's dupes were becoming more unpredictable, the source of Madrox's powers, "what's coming" and "uber". This knowledge caused him to turn to drinking. Finally, before Madrox could reabsorb this dupe, he shot a dirty cop and was gunned down by the police in order to spare Madrox Prime the burden of knowledge.[35]
  • Cortex - One of two dupes sent into the only remaining two futures with mutants.[46] Cortex encountered Damian Tryp and was altered to served Tryps purposes.[56]
  • Scoutmaster dupe - One of Jamie's dupes worked as a scoutmaster for a year.[88]
  • Vengeful dupe - Similar to the X-Factor dupe, this dupe is Jamie's darker side and tried to kill Hector Muñoz.[89]
  • Sean Madrox - Sean was actually a child conceived by Siryn and a dupe.[13] However, as a child of a dupe, Sean possessed the same attributes of a dupe and was inadvertently absorbed by Madrox Prime.[54]
  • R.S.C. dupe - One of Madrox's dupes spent eighteen months with the Royal Shakespeare Company.[42]
  • Chaos War resurrected dupes - When the Chaos King put the living asleep and opened the underworld, three Madrox dupes were among the resurrected.[90] They were all later killed in battle against the Carrion Crow.[91]
  • Gofer dupe - One of Madrox's dupes worked as a gofer on the set of Supernatural for six months, and learned some things about warding off demons.[92]
  • Bloodbath dupe - Dupe created at Imperial Studios while the X-Factor crew was searching for Bloodbath. Later killed by Terry Roland, and possessed by Bloodbath to murder Madrox Prime.[62]
  • Matt Rocks, Esq. - One of the dupes sent to study law. He moved to Los Angeles and became an entertainment lawyer. Madrox Prime chose not to reabsorb Matt in exchange for Matt sending him half of his earnings. Unlike Madrox Prime, Matt has jet black hair, tanned skin, and constantly wears sunglasses. Also, he is portrayed in a more comical fashion than many of the other dupes.[93]
  • Bunker Dupe - After the death of Jamie Prime, one dupe managed to survive -- it is unconfirmed if Matt Rocks or Father John Maddox survived the death of Jamie Prime, but seems unlikely based off of the nature of Jamie's powers established in Multiple Man -- by having sealed himself in an airtight bunker on Muir Island sometime before the events of Madrox and the following X-Factor (Vol. 3), which delayed the adverse health effects of Jamie Prime's death. In an effort to put off his inevitable death, the dupe stole a Temporal Beacon from Bishop and traveled into the future, creating dupes along the way that resulted in a future which was ruled and policed by Madri.[94] This dupe was revealed to have personified a treacherous, megalomaniacal aspect of Jamie Prime's personality and had originally locked himself in the bunker in order to find a way to become the Prime Jamie.[95] Dubbing himself "Emperor Prime," he was the leader of a totalitarian regime in the future he had conquered, though he was opposed by a Resistance also made up of Madri, led by that reality's Jamie Prime's orphaned son, Davey Miller.[96] The Emperor Prime had killed off most of the world's superheroes, starting with Beast after he had created a serum that would make the Emperor Prime the Prime Jamie.[95] The Emperor Prime ended up undergoing a change of heart after killing a heroic version of himself who had traveled to the past to stop him, thus becoming said heroic version himself.[97] This Madrox ultimately managed to fix the timeline by committing assisted suicide that created a chain reaction, killing all of the army of duplicates, good and bad, except for one that was in a different reality at the time.[98] Other notable Dupes from this time travel adventure include:
    • Lieutenant Madrox - Emperor Prime's second-in-command who, after the Emperor Prime's change of heart, took over control of the empire and used its army to invade the past, defeating the combined forces of the heroic Emperor, the X-Men, and the New Mutants. Lieutenant Madrox managed to steal and take the serum that turned the Emperor Prime into the Prime Jamie, briefly managing to become "Co-Prime," but was then reabsorbed by the Emperor.[99]
    • Cloak - One of a group of dupes from the Resistance against Emperor Prime who were sent into the timestream to find help, this dupe was specifically sent to find Doctor Strange. He instead found himself in Earth-TRN591 and met the Sorcerer Supreme of that world, Doctor Stark. Stark refused to assist Jamie's time but did take him on as a student. After sixty years of study, Jamie, taking the name and Cloak of that world's deceased Cloak, collected the other dupes that had been sent into the timestream and traveled back to assist Jamie Prime in saving their world.[100] Cloak ultimately died when Jamie Prime was killed, saving the Past.[98]
    • Hulk - One of a group of dupes from the Resistance against Emperor Prime who were sent into the timestream to find help. This dupe ended up on Earth-807128 and became a Hulk after drinking Gamma-irradiated water. He joined the Hulk Gang for a while before Cloak returned to collect him.[100] Hulk assisted Jamie Prime in killing himself in order to stop the invading evil Multiple Men, and died himself as a result.[98]
    • Deadpool - One of a group of dupes from the Resistance against Emperor Prime who were sent into the timestream to find help. This dupe ended up on Earth-928 and was semi-involuntarily turned into a "the Greatest Warrior of All Time" by the Freakshow using old Weapon Plus plans. He was collected by Cloak to travel back to save their time.[100]. Deadpool ultimately died when Jamie Prime was killed, saving the Past.[98]
    • Cable - One of a group of dupes from the Resistance against Emperor Prime who were sent into the timestream to find help, this dupe was specifically sent to find the X-Men. This dupe ended up Earth-4935 and joined Clan Askani. The dupe ended up committing to the Clan's cause and spent years helping to fight back against Apocalypse, becoming bonded with the Technarchy at some point. He was collected, unwillingly, by Cloak to travel back to save their time.[100]. Cable ultimately died when Jamie Prime was killed, saving the Past.[98]
    • Bartender Dupe - One of a group of dupes from the Resistance against Emperor Prime who were sent into the timestream to find help, this dupe was specifically sent to find Tony Stark. This dupe ended up on an Earth where everyone hangs out on a beach wearing swimsuits and got a job as a bartender at Bobbie's Beach Bar. The dupe was forgotten and ended up not being collected by Cloak with the rest. He returned to the past after the death of Jamie Prime, somehow having survived (Likely due to not being on Earth-616 at the time), leaving his new world after it "took a turn for the worst" and wearing an M tattoo over his eye identical to that which the original Jamie had received on Earth-1191. This dupe then took the serum Beast had created, making him the new and only Jamie Prime, and set out to meet the original Madrox's widowed wife and child.[100][98]


Madrox has acquired extensive knowledge and skills via his duplicates' experiences, such as human anatomy,[82] speaking Russian,[78] and Shaolin monk stealth techniques.[80] Madrox is also a certified lawyer.[86]



James Madrox (Earth-616) from X-Men Annual Vol 1 15 002

Multiple Man's special suit

Kinetic Dampening Suit: Madrox once wore a suit that damped kinetic impacts so that he wouldn't duplicate from accidental impacts.


  • The plural form of Madrox has been given as both "Madri"[citation needed] and "Madroxes".[101]
  • The Madri apparently can have different food allergies from each other.[75]
