Inferno

• Core Identity: Inferno was a massive 1989 Marvel Comics crossover event centered on a demonic invasion of New York City, orchestrated by the demons of Limbo and the corrupted Madelyne Pryor, clone of Jean Grey, in her bid for revenge against the X-Men.
• Key Takeaways:
  • Role in the Universe: Inferno served as the explosive climax to years of simmering plotlines across the X-Men family of titles, primarily resolving the tragic identity crisis of madelyne_pryor and the long-running corruption of illyana_rasputin's soul. It was a turning point for the X-Men franchise, defining its tone for the early 1990s.
  • Primary Impact: The event's fallout was immense: it led to the dissolution of the then-current X-Men team, the transformation and ultimate death of Madelyne Pryor as the Goblin Queen, the rescue of Nathan Christopher Summers, the full revelation of mister_sinister's machinations, and the de-aging of Illyana Rasputin to childhood after she purged her demonic self.
  • Key Incarnations: This is a quintessentially Earth-616 comic book event with no direct adaptation in the Marvel Cinematic Universe (MCU). However, its core themes and characters have been adapted in other media, most notably in the X-Men '97 animated series, which heavily features Madelyne Pryor's transformation into the Goblin Queen. A 2021 comic series also titled Inferno is a completely separate story set in the Krakoan Age.

The Inferno crossover was the culmination of long-form storytelling, a signature of writer Chris Claremont's legendary run on Uncanny X-Men. The seeds for the event were sown years prior, in separate but thematically linked storylines primarily developed by Claremont in Uncanny X-Men and The New Mutants, and by Louise Simonson in X-Factor. The first official appearance of the event branding was in Uncanny X-Men #239 (December 1988). The core storyline ran from January to February 1989, dominating Marvel's mutant-centric titles and spilling over into numerous other books, including The Avengers, Daredevil, Power Pack, and The Amazing Spider-Man. The creative architects of the core event were:

• Chris Claremont (Writer, Uncanny X-Men): The driving force behind Madelyne Pryor's tragic arc and the X-Men's emotional turmoil.
• Louise Simonson (Writer, X-Factor, The New Mutants): Masterminded the return of jean_grey, which set Madelyne's downfall in motion, and chronicled Illyana Rasputin's struggle with her demonic half.
• Walter Simonson (Writer, X-Factor): Co-plotted the X-Factor side of the story, focusing on the team's battle against the newly crowned Goblin Queen.
• Marc Silvestri (Penciler, Uncanny X-Men): His gritty, detailed artwork defined the look of the X-Men during this era and brought the horror of demonic New York to life.
• Bret Blevins (Penciler, The New Mutants): His expressive, almost cartoonish style perfectly captured the surreal and terrifying nature of limbo and its denizens.
• Walter Simonson (Penciler, X-Factor): Provided the art for the team's direct confrontation with the demonic forces.

Inferno was designed to resolve several dangling plot threads that had become almost unmanageably complex. What was Madelyne Pryor's true origin? Would Illyana Rasputin (Magik) finally succumb to her demonic heritage? The event provided brutal, definitive answers, shaking the foundation of the X-Men universe and setting a darker, more intense tone for the decade to come.

The cataclysm known as Inferno was not a single, spontaneous event but the confluence of two separate demonic plots, each born from years of pain, manipulation, and corruption.

The in-universe origins of Inferno are rooted in two parallel tragedies: one forged in a demonic dimension and the other in a geneticist's laboratory. Illyana Rasputin's Hell: The first plotline originated in the demonic dimension known as Otherplace, or limbo. Years prior, the seven-year-old Illyana Rasputin, sister of the X-Man colossus, was abducted by the demon lord Belasco. While the X-Men rescued her mere seconds later on Earth, time moved differently in Limbo; Illyana returned as a 13-year-old sorceress and warrior. During her years of torment, Belasco corrupted a portion of her soul, creating magical “bloodstones” and forging her life force into the Soulsword. She eventually overthrew Belasco to become the ruler of Limbo, but the demonic corruption, her “Darkchilde” persona, remained a part of her. Two of Limbo's chief demons, S'ym and N'astirh, saw Illyana's humanity as a weakness. The brutish S'ym wished to usurp her throne through pure force, while the cunning N'astirh devised a more insidious plan. N'astirh sought to manipulate Illyana into fully embracing her demonic side, believing this would make her a more powerful (and controllable) queen. His ultimate goal was to open a permanent, massive portal between Limbo and Earth, allowing their hordes to conquer the mortal plane. He began whispering in her ear, preying on her insecurities and pushing her to use her dark magic, knowing each use brought her closer to damnation. Madelyne Pryor's Revenge: The second, and more personal, plotline centered on Madelyne Pryor. Initially believed to be a human pilot, Madelyne was in fact a clone of Jean Grey, created by the master geneticist mister_sinister. Sinister's goal was to create a perfect genetic pairing for Scott Summers, hoping their offspring would be a mutant of immense power. The plan worked: Scott met, fell in love with, and married Madelyne, and they had a son, Nathan Christopher Summers. Their happiness was shattered when the original jean_grey was discovered alive at the bottom of Jamaica Bay. Consumed with guilt and a sense of responsibility, Scott abandoned Madelyne and his son to reunite with Jean and form x-factor. This abandonment sent Madelyne into a spiral of depression and rage. During the “Fall of the Mutants” event, the X-Men faked their deaths, leaving Madelyne utterly alone and believing her friends were gone. It was in this vulnerable state that N'astirh found her. He offered her a deal: in exchange for her help in opening the portal to Earth, he would help her locate her missing son (who had been kidnapped by Mister Sinister's marauders) and grant her the power to exact revenge on Scott Summers and the world that had taken everything from her. Consumed by grief and a burgeoning psychic echo of the phoenix_force from her genetic template, Madelyne agreed. She was transformed into the sensual, terrifying Goblin Queen, her humanity sacrificed for demonic power and a burning need for vengeance. These two plots converged when N'astirh manipulated both women, using Illyana's teleportation discs to create the gateway and Madelyne's magical might to fuel it, unleashing hell on Earth.

There has been no direct adaptation of the Inferno storyline within the Marvel Cinematic Universe (MCU) or its associated properties. The event is deeply tied to decades of X-Men comic book continuity that has not yet been established in the MCU. However, key characters and thematic elements have appeared in other Marvel screen adaptations:

• The New Mutants (2020 Film): While not part of the MCU, this film provided the most significant on-screen depiction of illyana_rasputin, played by Anya Taylor-Joy. The film heavily explored her traumatic upbringing in Limbo, her use of teleportation stepping discs, and her possession of the Soulsword. It visually represented Limbo and featured the demon S'ym as an antagonist, capturing the essence of Illyana's half of the Inferno saga.
• X-Men '97 (Animated Series): This critically acclaimed continuation of the classic 1990s animated series directly adapts the core emotional story of Madelyne Pryor. The series depicts her as a clone of Jean Grey created by Mister Sinister, her marriage to Cyclops, the birth of Nathan, and Scott's emotional turmoil upon the original Jean's return. In the episode “Fire Made Flesh,” a distraught Madelyne is manipulated by Sinister (filling the narrative role of N'astirh) and transforms into the powerful and vengeful Goblin Queen, directly mirroring her comic arc and providing the most faithful adaptation of her Inferno journey to date.

Before the first demon set foot in Manhattan, the stage was meticulously set. In Uncanny X-Men, Madelyne Pryor, having lost her husband and her friends, began having horrific nightmares, which were psychic probes from N'astirh and S'ym. She formed a pact with N'astirh during a dream state. Meanwhile, in The New Mutants, Illyana Rasputin's control over Limbo and her own Darkchilde persona was visibly slipping. She grew more aggressive, her demonic form appearing more frequently, and her teleportation discs became increasingly erratic, often taking her teammates on terrifying detours through Limbo. In X-Factor, the team was unaware of Madelyne's plight, focused on their public duties and the mystery of baby Nathan's kidnapping.

The event kicked off in earnest when N'astirh, using a combination of computer logic and black magic, tricked Illyana into opening a massive, stable portal above the Empire State Building. Demonic energy flooded into New York City, causing widespread chaos. The city itself became a living entity, a malevolent character in the story:

• Mailboxes grew teeth and devoured letters.
• inanimate objects like cars and telephone poles came to life, attacking citizens.
• The laws of physics became suggestions, with buildings twisting into unnatural shapes.
• Everyday people were possessed by minor demons, their worst impulses amplified.

The crossover nature of the event was showcased here, with non-mutant heroes being drawn into the chaos. Spider-Man found himself battling a possessed Hobgoblin (Jason Macendale) who had been granted true demonic power. Daredevil fought to protect the innocent in a Hell's Kitchen that had become literal. The avengers battled demons and tried to contain the city-wide destruction.

Amidst the city-wide chaos, the core conflicts of the story came to a head in brutal, personal confrontations.

• Madelyne Pryor vs. Jean Grey: The climax of the X-Factor storyline. The Goblin Queen, seated on a throne of twisted metal in Times Square, held her son Nathan hostage. She confronted Jean Grey, forcing a psychic and physical battle. During the fight, Mister Sinister's involvement was revealed to both X-Factor and the X-Men. Sinister admitted to creating Madelyne and manipulating her entire life. In her final, desperate act of spite, Madelyne linked her mind with Jean's and killed herself, attempting to drag Jean with her. She was only stopped when the sliver of the Phoenix Force that had given her sentience chose to return to Jean, along with all of Madelyne's memories, finally making Jean whole but burdening her with her clone's immense pain and trauma.
• Illyana Rasputin vs. Darkchilde: The focus of The New Mutants tie-in. As the invasion raged, Illyana was forced to fully embrace her Darkchilde form to battle S'ym, who had been empowered by the transmode virus. The battle was a struggle for her very soul. Realizing she could not win and that her demonic power was the key to the invasion, Illyana made the ultimate sacrifice. She used all her power to forge a massive stepping disc, not through space, but through time. She pulled her innocent, six-year-old self from the moment before Belasco first corrupted her and brought her to the present. The Darkchilde and the demonic Limbo, unable to exist without their anchor, were seemingly erased. In her place was left the pure, uncorrupted child Illyana, her memories of her time as Magik gone. Her brother, Colossus, was left to care for the little sister he had lost and just regained.
• N'astirh's Gambit: The demon mastermind's plan was to make the demonic gateway permanent. He gathered ten specific mutant babies, including Nathan Summers, to be used in a sacrificial pentagram atop the Empire State Building. He was ultimately defeated by the combined might of the X-Men and X-Factor, who disrupted his spell. In a final, desperate move, he merged with the transmode-virus-infected S'ym, but was destroyed by the New Mutants.

Inferno left no corner of the mutant world untouched.

• The X-Men: Already operating in secret after faking their deaths, the team was emotionally shattered. They learned of Sinister's manipulations, the truth about Madelyne, and were forced to ally with X-Factor. The revelations caused deep rifts, particularly for Havok, Madelyne's former lover, and Colossus, grieving for his sister. The team officially disbanded shortly after, with its members scattering across the globe.
• X-Factor: With Madelyne dead and the truth revealed, the original five X-Men were finally free to be a team without the lie that had defined their existence. They took custody of baby Nathan, becoming his protectors and a more public-facing superhero team.
• The New Mutants: The team was left reeling from the loss of Illyana as they knew her. Their powerhouse sorceress was now a child they had to protect. This loss of power and innocence fundamentally changed the team's dynamic, leading them towards a new, more militaristic direction under the future leadership of cable.
• Mister Sinister: Though his pawn Madelyne was dead, his ultimate goal—the creation of Nathan Summers—was a success. His role as a master manipulator of the Summers and Grey bloodlines was cemented, establishing him as a top-tier X-Men arch-villain for decades to come.

• Madelyne Pryor (The Goblin Queen): The tragic heart of Inferno. A clone given life and love, only to have it all violently stripped away. Her transformation into the Goblin Queen was not one of pure evil, but of absolute, bottomless grief and rage. Her demonic powers included magical control over inanimate objects, telekinesis, and the ability to project hellfire.
• Illyana Rasputin (Darkchilde): The secondary protagonist, locked in a desperate battle for her own soul. As the Darkchilde, she wielded immense demonic power, the Soulsword, and commanded the legions of Limbo. Her internal conflict between her human conscience and the demonic corruption that had festered since childhood was the catalyst for the entire invasion.
• N'astirh & S'ym: The demonic instigators. N'astirh was the brains, a master of magic and manipulation who saw mortals as pawns. S'ym was the brawn, a powerful and near-invulnerable demon who sought power through brute force. Their rivalry and conflicting methods ultimately proved to be their undoing.

• The X-Men: This roster (Storm, Wolverine, Colossus, Rogue, Psylocke, Dazzler, Longshot, Havok) was the team that believed itself dead to the world. They were drawn into the conflict when they discovered Madelyne's survival and transformation. Their primary role was fighting the Marauders and confronting the emotional truth of Madelyne's origins.
• X-Factor: Comprised of the original five X-Men (Cyclops, Jean Grey, Iceman, Beast, Angel), this team had the most personal stake in the fight. They fought to save Nathan Summers, Cyclops's son, and were forced to confront Scott's devastating abandonment of his wife, which directly led to the crisis.
• The New Mutants: This team (Cannonball, Sunspot, Wolfsbane, Warlock, Mirage, etc.) fought the war on two fronts: in the streets of New York and within the heart of Limbo itself. Their story was the most personal, as it revolved entirely around saving their friend Illyana from herself.

• Mister Sinister: The true puppet master. The entire tragedy of Madelyne Pryor was a direct result of his decades-long eugenics program. While he did not directly participate in the demonic invasion, his actions created the Goblin Queen, and the event's climax was the first time the X-Men truly understood the scope and horror of his influence on their lives.
• The Marauders: Sinister's elite team of mutant assassins, including Sabretooth, acted as his enforcers, fighting the X-Men in the sewers beneath the possessed city.

This major crossover directly builds on Inferno's legacy. The central plot revolves around the infant Nathan Summers, who was sent to the future to save him from a techno-organic virus. The story reveals that Cable and his evil clone, Stryfe, are the adult versions of the baby at the heart of Inferno, making the consequences of Mister Sinister's grand experiment a central pillar of the X-Men universe.

It is critically important to distinguish the 1989 event from the 2021 miniseries of the same name. Written by Jonathan Hickman as the finale to his tenure on the X-Men books, this Inferno is not a sequel or a remake. The title is thematic, referring to the personal and political “hell” of the new mutant nation of krakoa.

• Plot: The 2021 story focuses on mystique's quest to resurrect her long-dead wife, Destiny, against the wishes of professor_x and magneto. It reveals the deep secrets behind Krakoa's founding, particularly the role of moira_mactaggert.
• Connection: The only connection is the shared name and the theme of long-hidden secrets and betrayals leading to a fiery confrontation that changes the status quo. There are no demons from Limbo or a Goblin Queen.

Titled “What If the X-Men Had Lost Inferno?”, this issue explores a dark timeline where the heroes fail. In this reality, N'astirh's spell is successful, and the portal to Limbo becomes permanent, merging a large part of Earth with the demonic realm. S'ym, now the uncontested ruler, leads his demonic hordes across the planet. The story follows a small band of survivors, led by Doctor Strange and Wolverine, in a desperate, losing battle against a hell on Earth.

As mentioned, this series provides the most prominent modern adaptation of the Inferno saga's core themes. It streamlines the plot, replacing the demonic pact with Mister Sinister's direct genetic and psychological manipulation of Madelyne. The result is the same: a powerful, heartbroken woman remade into the Goblin Queen, seeking revenge on Cyclops and Jean Grey. The adaptation was praised for capturing the emotional weight of Madelyne's tragedy, which was the true heart of the original comic event.

During the Secret Wars event, the patchwork planet of Battleworld was made of different domains from destroyed alternate realities. One of these domains was “Inferno,” a version of Manhattan that had been permanently overrun by demons. The tie-in miniseries, also titled Inferno, followed a version of colossus leading a small team of X-Men on an annual suicide mission into the demonic territory to rescue his sister, illyana_rasputin, who in this reality had fully succumbed and become the demonic queen of the realm.
