For over four decades, Superman has been a cinematic icon, saving the world from cataclysmic threats on the big screen. His movie adventures have firmly established his most famous adversaries in the public consciousness, with audiences witnessing his battles against the obsessive genius of Lex Luthor and the Kryptonian might of General Zod multiple times. These villains have provided formidable challenges, pushing the Man of Steel to his physical and ethical limits. However, Superman’s comic book rogues’ gallery is one of the most diverse and powerful in all of fiction, filled with cosmic tyrants, technological terrors, and psychological nightmares who have yet to receive their cinematic due.
This list celebrates seven of the strongest and most fascinating Superman villains who have never appeared in a live-action movie. These are antagonists who could provide fresh conflicts, expand the scope of Superman’s cinematic world, and challenge him in ways audiences have never seen before. With the DCU using Superman as a launching pad and the Man of Steel being introduced as a key player, these are the villains we hope to see in theaters sooner rather than later.
1) Brainiac
Second only to Lex Luthor in Superman’s hierarchy of villains, Brainiac is a hyper-intelligent alien entity whose threat is not one of conquest, but of cold, clinical preservation. His horrifying methodology sees him travel the cosmos in an iconic skull-shaped ship, seeking out advanced civilizations merely to consume their knowledge. In a monstrously calculated process, he shrinks and bottles one of a planet’s major cities as a sample, and to ensure his prize remains unique, he then eradicates the original civilization entirely. This makes his conflict with Superman deeply personal, as the bottled Kryptonian city of Kandor is among his most cherished trophies.
This calculating nature was put on full display in Geoff Johns and Gary Frank’s “Brainiac” storyline, where his arrival on Earth was treated as an invasion of unimaginable horror. Rather than engaging in a simple brawl, Brainiac’s drones and superior technology overwhelmed the planet’s defenses, forcing Superman into a desperate battle of wits. Because he is driven by a terrifyingly detached logic that views entire cultures as data to be collected and discarded, he represents a cerebral nemesis whose intelligence is as dangerous as any physical blow.
2) Mongul
The despotic ruler of the mobile planet-sized battlestation known as Warworld, Mongul is a galactic tyrant whose name is synonymous with brutal conquest. Created by Len Wein and Jim Starlin, he possesses strength and durability sufficient to fight Superman toe-to-toe, but his true menace lies in his sadistic cruelty and love for gladiatorial combat. Mongul travels the stars, subjugating entire populations and forcing their greatest champions into his fighting pits for his own amusement. Furthermore, Warworld itself is an ultimate weapon, capable of laying waste to entire systems, even though Mongul often prefers the intimacy of breaking his opponents’ bodies and spirits himself.
Mongul’s most defining moment of psychological warfare came in Alan Moore and Dave Gibbons’ classic story, “For the Man Who Has Everything,” where he gave Superman a “gift”: a parasitic plant called the Black Mercy that trapped the hero in a perfect fantasy of life on Krypton. This intimate cruelty was later matched by his capacity for mass destruction during the “Reign of the Supermen!” event. There, he allied with the Cyborg Superman to help orchestrate the complete annihilation of Coast City, an act of genocide involving millions that cemented his reputation as one of the DC Universe’s most monstrous villains.
3) Metallo
The villain known as Metallo is a tragic fusion of man and machine, born from the mangled remains of John Corben. Depending on his origin, Corben was a soldier, mercenary, or common crook who suffered a catastrophic accident, only to have his brain transplanted into a powerful cybernetic body. This robotic chassis gives him immense strength and a near-indestructible endoskeleton, but its true danger to Superman comes from its heart of pure Kryptonite. This radioactive core turns him into a walking anti-Superman weapon, weakening the hero with his mere presence and turning any confrontation into a desperate fight for survival.
First appearing in a story by Robert Bernstein and Al Plastino, Metallo fundamentally alters the rules of engagement. Against him, Superman’s powers are drained, forcing him to rely on strategy and environmental advantages over brute force. This dynamic has made him a recurring pawn of military generals and Lex Luthor, who frequently upgrade his systems and exploit his hatred for Superman. The DCU already has a Metallo Easter egg, so the villain might pop in a future live-action project.
4) Parasite
Rudy Jones was a lowly janitor at S.T.A.R. Labs whose life was irrevocably altered after an accident exposed him to experimental bio-chemicals. The event transformed him into the monstrous Parasite, a purple-skinned horror with the grotesque ability to absorb the life force, memories, and powers of anyone he touches. This makes him uniquely dangerous to Superman, as every punch the hero lands allows Parasite to siphon more of his vast Kryptonian energy. He grows stronger, larger, and more powerful as Superman becomes perilously weak, turning the hero’s greatest asset into his greatest liability.
Parasite’s every action is driven by an insatiable hunger, a condition that makes him a profoundly tragic figure who must feed on others simply to exist. As he absorbs more energy, he can reach to kaiju-like proportions, but this physical power comes at a terrible psychological cost. The memories of his victims flood the Parasite’s mind, creating a cacophony of voices in his head that makes him dangerously unstable. He is a walking plague whose very nature is an inversion of Superman’s, a being who takes strength from others rather than giving it, representing a living embodiment of mindless consumption.
5) Cyborg Superman
The being known as Cyborg Superman is a terrifying perversion of the hero’s legacy, born from the shattered mind of astronaut Hank Henshaw. During the doomed flight of the space shuttle Excalibur, Henshaw and his crew, including his wife Terri, were bombarded by a cosmic radiation storm. Blaming Superman for not being there to save them, the dying Henshaw found his consciousness transferred into the shuttle’s computer systems. With his newfound ability to control any technology, he built a cybernetic body that mimicked Superman’s form, using the hero’s own DNA retrieved from his tomb to complete the disguise. At first, Cyborg Superman planned to use the hero’s symbol of hope to destroy his reputation and everything he protected.
Cyborg Superman’s plan unfolded during “Reign of the Supermen!”. Posing as the resurrected hero, he earned the world’s trust before revealing his true nature. In partnership with Mongul, he used alien technology to construct a massive city-engine in the center of Coast City, which detonated and completely annihilated its seven million inhabitants. The destruction of Coast City led directly to Green Lantern Hal Jordan’s fall from grace and transformation into the villain Parallax, a cataclysmic event that resulted in the destruction of the Green Lantern Corps. With Kryptonian-level powers and a consciousness that can possess any machine, Henshaw later became a Grandmaster of the Manhunters and a key officer in the Sinestro Corps, a recurring cosmic horror born from personal tragedy.
6) Manchester Black
A far cry from the cosmic tyrants and tragic monsters, Manchester Black is a uniquely modern threat because his conflict with Superman is purely ideological. Created by Joe Kelly and Doug Mahnke, Black is a powerful British telekinetic and telepath who leads a team of superhumans known as The Elite. He operates under the belief that superheroes who refuse to kill their enemies are ineffective and outdated. As such, Black wants to change the world by force, proving that his brand of lethal justice is more effective than Superman’s moral code. Because of that, he targets Superman specifically because he views the hero’s principles as the single greatest obstacle to a safer world, making their struggle a battle for the soul of heroism itself.
Black’s methodology and purpose are fully explored in the landmark story “What’s So Funny About Truth, Justice & the American Way?”. In this narrative, The Elite make their debut and gain immense popularity by executing supervillains, a strategy the public embraces as a permanent solution. This places Superman in a difficult position, forcing him to defend his principles against a rival who has captured the world’s approval. The conflict culminates in a massive showdown where Superman, seemingly pushed past his breaking point, uses his powers with terrifying precision to defeat The Elite. He gives Black a simulated stroke with his heat vision and dismantles the rest of the team, proving he could adopt their methods if he wished. The true victory comes when Black, believing Superman has become a killer, breaks down, showing that Superman’s restraint is his greatest strength.
7) Mister Mxyzptlk
At first glance, Mister Mxyzptlk appears to be more of a nuisance than a genuine threat. A diminutive imp from the 5th Dimension, he possesses the nigh-omnipotent ability to warp reality according to his every whim, capable of turning cities to gingerbread or animating statues with a simple thought. His motivations are based on curing his own infinite boredom, and he considers our three-dimensional reality a playground with Superman as his favorite toy. Typically, Mister Mxyzptlk’s visits involve subjecting the Man of Steel to a series of surreal challenges the villain can only be defeated if he is tricked into saying or writing his name backwards, “Kltpzyxm,” which forcibly banishes him to his home dimension for a minimum of ninety days.
The true danger of Mister Mxyzptlk, however, lies in the sheer scale of his power coupled with his fickle personality. While he usually engages in harmless pranks, a shift in his mood could have catastrophic consequences for all of existence. This terrifying potential was fully realized in Alan Moore’s seminal story, “Whatever Happened to the Man of Tomorrow?”. In this tale, Mxyzptlk grows tired of his old games and decides to become truly evil. He sheds his playful persona, reveals a more monstrous true form, and unleashes an apocalypse of pure malicious chaos, murdering Superman’s friends and pushing the hero to his psychological and physical limit.
