The Jackal (Miles Warren)

Part 1: The Dossier: An At-a-Glance Summary

Part 2: Origin and Evolution

Publication History and Creation

Professor Miles Warren first appeared in Amazing Spider-Man #31 in December 1965, created by writer Stan Lee and artist Steve Ditko. In this initial appearance, he was simply a supporting character, the science professor at Empire State University where Peter Parker and Gwen Stacy were students. For nearly a decade, he remained a background figure, a mundane part of Peter's civilian life. The character's villainous transformation was conceived by writer Gerry Conway, who was looking for a new, psychologically driven antagonist to follow the monumental death of Gwen Stacy. Conway, along with artist Ross Andru, reinvented Warren as the supervillain The Jackal in Amazing Spider-Man #129 (February 1974), the very same issue that introduced the Punisher. The Jackal's motivation was explicitly tied to Gwen's death, making him a deeply personal foe for Spider-Man. This storyline culminated in the first “Clone Saga” in the mid-1970s, a shocking story for its time that introduced the concept of Spider-Man and Gwen Stacy clones, seemingly ending with the Jackal's death. However, the character's legacy was so profound that he was resurrected for the infamous and sprawling “Second Clone Saga” of the 1990s. This event, intended to re-energize the Spider-Man line, became one of the most complex and controversial periods in comic book history, cementing The Jackal's reputation as a master manipulator and a source of existential dread for Peter Parker. He has since returned in various forms and storylines, most notably in Spider-Island and Dead No More: The Clone Conspiracy, each time updated to reflect new anxieties surrounding genetic science and identity.

In-Universe Origin Story

Earth-616 (Prime Comic Universe)

Miles Warren was a highly respected professor of biochemistry at Empire State University (ESU). He was a brilliant scientist but a lonely and reserved man. Among his students were Peter Parker, Harry Osborn, and Gwen Stacy. Warren developed a secret, deeply paternal, and ultimately inappropriate affection for Gwen. He saw her as the epitome of purity and intelligence, the daughter he never had. This fragile peace shattered when Gwen Stacy was murdered by the Green Goblin during a battle with Spider-Man. Warren's mind, already unstable, fractured completely. Consumed by grief and rage, he refused to accept her death. He obtained cell samples from both Gwen and Peter Parker that he had collected during a class project. His assistant, Anthony Serba, had already perfected a cloning process. In his madness, Warren blamed Spider-Man for failing to save Gwen and became obsessed with bringing her back and making the hero pay. When Serba discovered Warren's insane plan and realized the clones were developing full memories, he declared Warren's work an abomination. In a fit of rage, Warren murdered Serba. This act of violence was the final push into true villainy. To cover his tracks and create a new identity for his war on Spider-Man, he adopted the persona of “The Jackal,” a name inspired by his own self-loathing assessment of his scavenger-like actions. He designed a green suit and equipped himself with razor-sharp claws. He trained himself to peak physical condition, becoming a formidable acrobat and fighter. His master plan was to torment and destroy Spider-Man psychologically before killing him. He successfully created perfect clones of both Gwen Stacy and Peter Parker. He used the Gwen clone to gaslight Peter, making him believe the real Gwen had somehow returned. This culminated in a massive confrontation at Shea Stadium, where the clone of Spider-Man fought the original. The Jackal's plan unraveled when the Gwen clone, possessing all of the original's morality and love for Peter, turned on him. In the ensuing chaos, The Jackal was apparently killed in an explosion, and the Spider-Man clone was also thought to have perished. For years, this was the end of his story, a tragic tale of a man broken by loss.

Marvel Cinematic Universe (MCU)

Miles Warren, in his identity as The Jackal, does not exist within the continuity of the Marvel Cinematic Universe (Earth-199999). There have been no characters by that name or any direct adaptations of his storylines, such as the Clone Saga, in any MCU film or Disney+ series to date. While the MCU has explored themes of genetic engineering (the Super-Soldier Serum), artificial intelligence (Ultron), and attempts to defy death (Project T.A.H.I.T.I. in Agents of S.H.I.E.L.D.), these have not been linked to a character like Warren. It is worth noting that outside of the MCU, in Sony's The Amazing Spider-Man 2 universe, a viral marketing campaign for the film on the “Daily Bugle” Tumblr blog mentioned a “Dr. Miles Warren” as an ESU genetics professor, a clear nod to the comics. However, this universe is separate from the MCU (despite later multiverse connections in Spider-Man: No Way Home) and the character never appeared on screen. Should Marvel Studios ever decide to introduce The Jackal into the MCU, his origin would likely require significant adaptation. He could be presented as a disgraced former scientist from a major tech company like Stark Industries or even Oscorp, should that company be fully integrated into the MCU. His motivation could still stem from the loss of a loved one in a superhero battle, providing a grounded, contemporary reason for his hatred of Spider-Man and his turn towards the dark science of cloning.

Intellectual Abilities

Physical Abilities

Miles Warren has undergone several physical transformations throughout his history, each augmenting his abilities far beyond those of a normal human.

Equipment and Technology

Personality and Psychological Profile

The Jackal is a chilling portrait of intellectual arrogance corrupted by profound emotional trauma.

Marvel Cinematic Universe (MCU)

As The Jackal has not appeared in the MCU, his abilities can only be speculated upon. A cinematic adaptation would likely ground his science in the established rules of the universe.

Part 4: Key Relationships & Network

Core Associates & Creations

Arch-Enemies

Affiliations

The Jackal is notoriously a lone wolf, too arrogant and obsessive to work well with others. His “affiliations” are almost always temporary arrangements or organizations he himself has created to serve his purposes.

Part 5: Iconic Events & Storylines

The Original Clone Saga (Amazing Spider-Man #141-149, 1975)

This foundational storyline introduced The Jackal's core motivations and methods. After tormenting Peter with the inexplicable reappearance of Gwen Stacy, The Jackal reveals his identity as Professor Miles Warren. He explains his love for Gwen, his blame of Spider-Man, and the existence of both her clone and a clone of Spider-Man. The climax occurs at Shea Stadium, where the two Spider-Men fight until the Gwen clone and Ned Leeds intervene. The Jackal activates a bomb, seemingly killing himself and the Spider-Man clone. The original Spider-Man, left with two bodies, disposes of the clone's body in a smokestack, hoping to put the nightmare behind him forever. This story was revolutionary for its time, questioning the hero's very identity and leaving a lasting psychological scar.

The Second Clone Saga (1994-1996)

A sprawling, two-year-long epic that redefined The Jackal's legacy. The storyline began with the return of the Spider-Man clone from the 70s, who had survived and created a new life for himself as “Ben Reilly.” The Jackal also returns, revealing he had cloned himself as well. What followed was a massive, convoluted narrative where Warren unleashed a torrent of new clones, including the tormented Kaine and the shape-shifting Spidercide. The central, most damaging plot point was The Jackal's (and genetic tests') assertion that Ben was the original Peter Parker, and the man readers had followed for 20 years was the clone. This “revelation” was designed to fundamentally shake up the status quo, but it proved deeply unpopular. The saga ended with the reveal that a secretly resurrected Norman Osborn was the true mastermind, having manipulated Warren all along. Ben Reilly dies saving Peter, and his body degenerates, finally proving Peter was the original all along. The Jackal was once again believed to be dead.

Spider-Island (2011)

In this major event, The Jackal returned with a new, more bestial appearance, having further modified his own genetics. He allied himself with the Spider-Queen, a villain with control over the “human-spider” genome. Together, they used genetically modified bedbugs to spread a virus across Manhattan, giving ordinary citizens spider-powers. Their goal was to then “evolve” the populace into monstrous spider-creatures under the Queen's control. The Jackal acted as the lead scientist of the operation, reveling in the chaos of his city-wide experiment. He created a clone of Gwen Stacy with spider-powers and was ultimately defeated when a cure for the virus was developed and dispersed by Spider-Man and his allies.

Dead No More: The Clone Conspiracy (2016-2017)

This event saw Warren's most ambitious scheme to date. Operating from behind a corporate facade called “New U Technologies” and disguised in a crimson Anubis-themed suit, he initially presented himself as a resurrected Ben Reilly. He perfected a new form of cloning he called “reanimation,” which involved resurrecting the dead in new clone bodies with all their memories intact, requiring daily pills to maintain cellular stability. He resurrected countless friends and foes of Spider-Man, including Gwen Stacy, Doctor Octopus, and Captain Stacy, offering Peter a chance to have everyone he ever lost back. His true goal was to merge this technology with the Carrion Virus, creating a global pandemic that would force everyone to accept his “gift” or die. The plan failed catastrophically when the clones began to degenerate en masse, and he was ultimately defeated by Spider-Man and the “true” Ben Reilly, who had been resurrected and tortured by Warren for years.

Notes and Trivia

1) 2) 3) 4) 5)

1)
The name “Jackal” is a direct reference to the Egyptian god Anubis, the jackal-headed deity associated with death and the afterlife. This ties into Warren's obsession with resurrecting the dead.
2)
During the planning stages of the 1990s Clone Saga, the original intent was for Ben Reilly to be revealed as the one true Peter Parker and to permanently take over the role of Spider-Man. The immense negative fan reaction to this idea caused Marvel Comics to reverse course, leading to the convoluted ending where Norman Osborn was revealed as the mastermind and Peter was confirmed as the original.
3)
The Jackal's first appearance in Amazing Spider-Man #129 is highly notable as it is also the first appearance of Frank Castle, The Punisher. The Punisher was initially hired by the Jackal to assassinate Spider-Man.
4)
The character of Carrion, a villain with a death touch, was originally a degenerating clone of Miles Warren himself, created in a last-ditch effort to survive his apparent death in the first Clone Saga. The mantle of Carrion has since been passed to others.
5)
Gerry Conway, the creator of the Jackal persona, has stated in interviews that he killed Gwen Stacy because he couldn't imagine a realistic way for Peter Parker's story to progress if he married his college sweetheart. The Jackal was then created as a direct, monstrous consequence of that decision, embodying the grief and madness that such a loss could inspire.
