Spoiler Alert! This article contains spoilers for Ironheart.
After years of rumors and teases, Mephisto has finally made his Marvel Cinematic Universe debut in Ironheart, and in doing so has set up several other thrilling Marvel characters. After years of waiting, Marvel’s demonic manipulator has appeared in live-action, played by Sacha Baron Cohen. In doing so, the MCU timeline has been primed for some exciting Marvel characters.
Mephisto’s introduction in Ironheart opens the gates of Hell, literally and figuratively. It unlocks a darker side of the MCU filled with supernatural entities, demonic power brokers, and characters with deep comic roots tied to Mephisto’s hellish schemes. More than a simple cameo, Mephisto's inclusion hints at a large supernatural arc in Marvel’s future, and will surely have long-reaching consequences.
10 Ghost Rider Mephisto's Most Famous CreationGhost Rider’s entire origin is deeply rooted in Mephisto’s manipulation. This makes Ironheart’s introduction of the demon a clear signal that the Spirit of Vengeance may soon follow. In the comics, Johnny Blaze becomes Ghost Rider after making a desperate deal with Mephisto to save his father from death.

The agreement backfires. Mephisto instead bonds Blaze with the demon Zarathos, turning him into the flaming-skulled vigilante. This origin highlights Mephisto’s preferred tactic, exploiting grief and desperation to enslave souls.
With Mephisto now officially in the MCU, the groundwork is laid for Ghost Rider’s emergence as either a pawn or a rebel against his infernal master. Their shared history of betrayal and supernatural conflict offers rich storytelling potential. Whether through Johnny Blaze, Robbie Reyes, or Danny Ketch, Mephisto’s presence almost guarantees Ghost Rider’s future in the MCU.
9 Blackheart Mephisto’s SonIronheart's Mephisto reveal plants seeds for the introduction of Blackheart, Mephisto’s monstrous and rebellious son. In the comics, Blackheart is a powerful demon created from concentrated evil in a town plagued by violence. He often serves as both rival and heir to Mephisto’s throne, challenging his father’s rule.
Blackheart frequently clashes with heroes like Ghost Rider, Doctor Strange, and the X-Men. His introduction could allow these characters to also come to the forefront. Blackheart’s introduction also means the MCU could explore internal conflict within Hell’s hierarchy.
Ironheart suggests that demonic politics are indeed in play, with Mephisto openly mocking Dormammu when mistaken for him. Blackheart’s unique look and brutal power set would make for a striking onscreen villain. Whether as an enforcer, rebel, or full-blown antagonist, Blackheart’s connection to Mephisto makes him a logical and exciting next step in Marvel’s dark expansion.
8 Hellstrom Son Of SatanIn Marvel Comics, Hellstrom is the literal son of Satan. Daimon walks a morally complex line between exorcist, antihero, and full-on supernatural powerhouse. Ironheart's demonic themes and introduction of Mephisto lay the groundwork for Daimon’s appearance, possibly as part of a battle with greater Hellish threats.

Daimon was depicted in Hulu’s Helstrom series. However, it was short-lived and not connected to the MCU. With one Devil analog introduced with Mephisto, Satan himself could be round the corner.
Daimon Hellstrom’s unique weapon, the trident-like "Soulfire" staff, and his connections to both magic and Hell give him a dual role as both hunter and haunted. Hellstrom’s addition would deepen Marvel’s magical mythos and give fans a darker, more philosophical figure to explore the cost of living between two infernal worlds. It also opens the door to his sister, Satana.
7 Green Goblin Norman And Harry Osborn Are Corrupted By MephistoIronheart’s Mephisto introduction sets up a surprising twist on one of Spider-Man’s greatest foes: the Green Goblin. In The Amazing Spider-Man (vol. 5) #72, it’s revealed that Norman Osborn made a Faustian bargain with Mephisto for wealth and power. In return, Norman traded his own son, Harry Osborn’s soul.
This horrifying deal retroactively explains Norman’s rise and his descent into madness. It also explains the torment that Harry endured throughout his life. Bringing Mephisto into the MCU facilitates that storyline to be adapted, which could justify Norman Osborn’s eventual arrival in the main MCU timeline.
Audiences have only seen Willem Dafoe’s Green Goblin variant from Spider-Man: No Way Home. This could explain why there’s been no sign of an MCU-native Goblin, as Mephisto is yet to put his schemes in motion. He could even choose to manipulate Ned Leeds into becoming Hobgoblin, a long-suspected development.
6 Satannish A Fellow Hell LordWith Mephisto now part of the MCU, other Hell Lords like Satannish are likely to follow. In Marvel Comics, Satannish is a rival demon lord, created by Dormammu and known for making Faustian bargains like Mephisto’s deals. His inclusion would provide both a rival and a narrative foil to Mephisto, suggesting a Hellish civil war brewing beneath the MCU’s surface.

Ironheart drops hints about competing demonic agendas with references to Dormammu. It’s only a matter of time before the ruler of the Dark Dimension returns. He could do so by creating and unleashing Satannish.
His grotesque, four-faced design would make him a visually distinct villain. While his role in empowering mortal villains like the Lethal Legion makes him a narratively rich addition. Satannish would expand the realms of dark power beyond just Mephisto’s and Dormammu’s domain.
5 Belasco Lord Of LimboIronheart’s demonic revelations subtly open the door to the realm of Limbo and its terrifying ruler, Belasco. In the comics, Belasco is a sorcerer-turned-demon who governs Limbo. He has tangled with characters like Magik, the X-Men, and Doctor Strange.
Belasco’s dark magic, obsession with corruption, and use of bloodstones make him a natural fit for the increasingly mystical MCU. Belasco’s ties to Illyana Rasputin could serve as a connective bridge between the supernatural and mutant corners of the universe. In the comics, Belasco is the demon who teaches Illyana the dark magic that turned her into Magik.
Magik’s time in Limbo affects her character significantly, and with the MCU’s X-Men in the works, Belasco could be spotlighted. Belasco’s ancient, corrupted sorcery could become a key threat in the growing tapestry of dark magic. Especially as Marvel continues to explore characters from alternate realms and Hell-adjacent spaces.
4 Mys-Tech Board Corporation Who Sold Their Souls To MephistoAmong the more obscure but thematically perfect setups introduced through Mephisto’s arrival is the potential for the Mys-Tech Board. The group is a shadowy corporation that sold their souls for eternal life. In exchange for demonic power and influence, the board serves Mephisto while engaging in secretive, soul-harvesting operations on Earth.

Their morally bankrupt business model could tie directly into Ironheart’s themes of technological ambition corrupted by dark forces. A reimagined Mys-Tech in the MCU would offer a powerful metaphor for corporate greed meeting supernatural evil. They could serve as recurring villains across multiple shows and projects.
Mys-Tech (sometimes spelled MyS-TECH) could manage magical artifacts, manipulate public perception, and even work with street-level dark operatives. With Mephisto’s arrival, Mys-Tech’s soul-trading schemes would fit seamlessly into the MCU’s unfolding magical economy. Their reveal could further cement Mephisto as Marvel’s most prolific manipulator.
3 Master Pandemonium Supervillain Created By MephistoMaster Pandemonium is one of Marvel’s strangest and most tragic villains. A failed actor named Martin Preston, he loses his soul to Mephisto. He is then transformed into a grotesque entity with demonic arms and a fractured psyche.
His body is literally a gateway to Hell, often used by Mephisto as a vessel for dark plans. With Ironheart introducing Mephisto and his Faustian deals, the MCU has laid the groundwork for Pandemonium’s horrifying origin. His ties to Wanda Maximoff and the lost souls of her children also make him a strong candidate for future crossover with Agatha Harkness.
Pandemonium represents how Mephisto’s promises of power ultimately destroy the soul. Ironheart’s magical corruption arc is the perfect narrative thread to bring such a tortured figure into live-action. As both a conduit for Mephisto and a villain in his own right, Pandemonium is perfect for Marvel’s supernatural future.
2 Malevolence Mephisto’s DaughterThough rarely seen, Malevolence, Mephisto’s daughter, is a powerful supernatural figure with ambitions to overthrow her father and rule Hell herself. Ironheart’s introduction of Mephisto opens the door for family drama in Marvel’s infernal hierarchy. Malevolence could be a wild card in the struggle for Hell's throne.
Related 10 Superhero Movies That Are Amazing From Start To FinishCertain superhero movies have been so groundbreaking and perfect that they maintain their quality throughout, and frequently reshape the whole genre.
Malevolence has served as an antagonist and uneasy ally to multiple Marvel heroes. She also once operated in Limbo, making her a potential link between characters like Belasco and Mephisto. Her rivalry with other Hell Lords and her magical abilities give her both personal and magical stakes in the MCU’s growing dark magic arc.
If Mephisto is playing the long game, Malevolence could emerge as an ambitious, chaotic force. She might even oppose him or even try to seduce mortal characters to her own cause. As the MCU continues, the next generation of Hell Lords must surely appear.
1 Nighthawk Hero Mephisto ManipulatesNighthawk, often seen as Marvel’s version of Batman, is a surprising but fascinating character to connect to Mephisto’s schemes. In several comic arcs, Kyle Richmond has been manipulated by Mephisto. Most notably, Mephisto poses as an angel to Nighthawk, and convinces him to kill Daredevil.
Ironheart’s finale suggests that even heroic figures are not immune to demonic manipulation. Nighthawk’s darker morality and vigilante tactics make him vulnerable to influence from Hell’s forces, especially if he’s promised power or redemption. Mephisto’s appearance means that Nighthawk could readily appear in a future Daredevil project or beyond.
A Mephisto-corrupted Nighthawk would offer a compelling mix of heroism, madness, and moral decay. He could serve as both an adversary and eventual ally, showcasing how Mephisto’s reach isn’t limited to villains; it can twist even the noblest of intentions into something monstrous. This is one of the most thrilling characters set up by Ironheart’s dynamic final episode.
