The character of Miles Warren was created by writer gerry_conway and artist ross_andru, first appearing in The Amazing Spider-Man #129 in February 1974. This issue is famously the first appearance of the Punisher, with Warren appearing simply as Peter Parker's biology professor. His transformation into the costumed supervillain, The Jackal, would not occur until over a year later in The Amazing Spider-Man #148 (September 1975), at the height of the original Clone Saga. The creation of the Jackal was a direct consequence of one of the most seismic events in comic book history: the death of Gwen Stacy in The Amazing Spider-Man #121. Gerry Conway, having made the controversial decision to kill off Spider-Man's first true love, sought a way to explore the profound grief and psychological fallout of that event. The Jackal became the living embodiment of that trauma—a character whose entire motivation was rooted in a twisted, pathological inability to let Gwen go. He represented a new kind of villain for Spider-Man: not one driven by greed or power, but by a deeply personal, psychological obsession that struck at the core of Peter Parker's personal life. The original Clone Saga was intended to be a contained, powerful story about loss and identity, though its concepts would later be expanded upon to a degree its creators likely never imagined.
The origin of the Jackal is a tragic tale of brilliance curdling into madness, a story that differs vastly between the comics and his near-nonexistence in film.
Dr. Miles Warren was a highly respected professor of biochemistry at Empire State University. He was a pioneer in the field of genetics and a mentor to many students, including Peter Parker and Gwen Stacy. However, beneath his professional exterior, Warren harbored a secret and deeply inappropriate fixation on Gwen. He saw her as the pinnacle of purity and intelligence, the daughter he never had, and, disturbingly, an object of romantic desire. He was completely unaware of her relationship with Peter Parker or her death at the hands of the green_goblin. Upon learning of her demise, Warren's fragile psyche shattered. He obtained cell samples of Gwen's that he had collected during a class project and, through his lab assistant Anthony Serba, began to delve into the forbidden science of cloning. His initial goal was to prove his theories, but it quickly became an obsession with bringing “his” Gwen back. When Serba discovered the true nature of their work and threatened to expose him, a panicked and unhinged Warren murdered him. To cover his tracks, he created a clone of Serba, a crude and imperfect copy that only furthered his descent into madness. Blaming Spider-Man for Gwen's death, Warren's grief mutated into a burning, irrational hatred. He adopted the persona of “The Jackal,” a name he associated with the predatory and cunning aspects of his new personality. He trained himself to peak physical condition and developed a green costume and clawed gauntlets. His master plan was to torment and destroy Spider-Man for his perceived crime. He successfully cloned both Gwen Stacy and Peter Parker, having deduced Spider-Man's secret identity through his intimate knowledge of Peter's life at ESU. This culminated in the first Clone Saga. The Jackal pitted Spider-Man against his own clone, with the life of ned_leeds hanging in the balance. In the final confrontation, the Gwen Stacy clone, horrified by what Warren had become, denounced him. The battle ended in a massive explosion that seemingly killed both the Jackal and the Peter Parker clone. For years, Miles Warren was believed to be dead, leaving behind a legacy of genetic terror and the lingering, nightmarish question of whether the surviving Spider-Man was the original or the clone. Decades later, it was revealed that this was only the beginning of his influence, as his research laid the groundwork for the sprawling, reality-questioning Clone Saga of the 1990s and his eventual, monstrous returns.
As of the current timeline, the character of The Jackal does not exist in the Marvel Cinematic Universe. Furthermore, Miles Warren has not appeared as a character in any meaningful capacity. His sole “appearance” is a subtle Easter egg in the film Spider-Man: Homecoming (2017). During a scene where Peter Parker is in a school hallway, a display case honoring the “Midtown School of Science & Technology Decathlon Team” is visible. On the list of faculty advisors for the team, the name “M. Warren” can be seen. This reference serves as a nod to comic book fans, confirming that a version of Miles Warren exists within the MCU's reality, likely as a science teacher at Peter's high school. However, this is the full extent of his presence. There is no indication that this version of Warren is a villain, a geneticist, or has any obsession with Gwen Stacy (who also does not exist in the MCU in the same capacity as her comic counterpart). Analysis of Adaptation: The inclusion of his name is purely speculative fuel. It allows future MCU storytellers the option to introduce him as a villain, perhaps in a more grounded take. An MCU adaptation could portray him as a former teacher of Peter's who, perhaps driven by the fallout of “The Blip” or another global catastrophe, delves into genetic engineering for either noble or nefarious purposes. His connection to Peter could be pre-established, creating a personal conflict. However, without a Gwen Stacy figure to fixate on, his core motivation would need to be significantly re-imagined. For now, he remains a name on a plaque, a ghost of a villain yet to be born.
Miles Warren's threat level comes from a lethal combination of intellectual prowess and physically enhanced capabilities, which have evolved over his villainous career.
The Jackal is defined by his obsessive and narcissistic personality. His love for Gwen Stacy is not genuine affection but a possessive, objectifying delusion. He sees her as a perfect object that was stolen from him, and his clones are merely his attempt to reclaim his “property.” He is arrogant, theatrical, and prone to lengthy monologues explaining his genius. He has a profound god complex, viewing his clones not as living beings with rights, but as clay for him to mold and discard at will. He is utterly devoid of empathy, and his charm and intelligence mask a deeply cruel and unstable psyche.
As Miles Warren has only appeared as a name, this analysis is purely speculative, based on common MCU adaptation patterns.
The Jackal's manipulative nature means he has few, if any, true allies. He views others as pawns or tools.
The Amazing Spider-Man #143-150. This is the foundational Jackal story. Driven by his obsession with the deceased Gwen Stacy, the Jackal creates clones of both Gwen and Spider-Man. He masterminds a series of psychological attacks on Peter Parker, culminating in a three-way battle between Spider-Man, his clone, and the Jackal. The storyline's climax sees the Gwen clone asserting her own identity and the Jackal seemingly perishing in an explosion alongside the Spider-Man clone. It ended with Peter Parker throwing the clone's body into a smokestack, cementing a dark secret in his past and raising, for the first time, the terrifying possibility that he might not be the original.
One of the most ambitious, sprawling, and controversial storylines in Marvel history. This saga revealed that the clone from the original story had survived and was living in exile as “Ben Reilly.” Ben returns to New York and becomes the heroic Scarlet Spider. The Jackal resurfaces, revealing that he too survived and has been manipulating events from the shadows for years. The core conflict of this era was the Jackal's claim, seemingly backed by scientific evidence from Dr. Seward Trainer, that Peter Parker was the clone and Ben Reilly was the original. This reveal shattered Peter's life, leading him to temporarily retire as Spider-Man and pass the mantle to Ben. The Jackal's long-term plan was to unleash the “Carrion Virus” to wipe out humanity, replacing it with a new race of his clones. Though it was ultimately revealed that Peter was the original after all, the psychological and emotional damage of the Jackal's master manipulation defined Spider-Man for a generation.
In this massive event, the Jackal returned as a key antagonist, working alongside the villainous Spider-Queen. Using genetically modified bedbugs, he unleashes a virus that gives all of Manhattan's inhabitants spider-powers, creating city-wide chaos that overwhelms the heroes. He demonstrates his continued evolution in genetics, mutating himself into a giant, multi-limbed Jackal monster. His goal was to create a new world of spider-human hybrids under the control of the Spider-Queen. The event showcased the Jackal's ability to operate on a global scale, moving beyond personal vendettas to world-threatening schemes.
This storyline saw the Jackal return with his most insidious plan yet. Operating as a mysterious benefactor in an Anubis mask, he establishes New U Technologies, a company that can bring the dead back to life in perfect clone bodies. He resurrects numerous deceased friends and foes of Spider-Man, including Gwen Stacy and Doctor Octopus, offering Peter a chance to undo his past failures. The ultimate twist revealed that this Jackal was not Miles Warren, but a resurrected Ben Reilly, driven mad by years of torture and death. The original Miles Warren was a subordinate clone, forced to serve the monster he had inadvertently created. The event was a dark exploration of the Jackal's legacy, showing how his science, even when wielded by another, inevitably leads to tragedy and chaos.
