Sometimes, Marvel‘s least intimidating villains showcase their full capabilities, to terrifying results. The Marvel Universe is home to an endless variety of antagonists, from street-level schemeers to multiversal conquerors. The sheer scale of Marvel’s gallery of villains underscores the power and presence of its most famous ones.
Every once in a while, the spotlight shifts to oft-dismissed villains. Some of Marvel’s most unassuming foes have suddenly become forces of unprecedented destruction. Whether through evolution or opportunity, former B- or C-listers have achieved feats that rival or even surpass Marvel’s greatest foes.
The Jackal
Miles Warren Became Spider-Man’s Biggest Villain During The Clone Saga
The Jackal smiles sinisterly at his desk in Marvel Comics
For years, the Jackal was little more than a footnote in Spider-Man’s rogues’ gallery. Miles Warren is a typical lab coat-wearing mad scientist with an animal gimmick and a cloning gig. He was introduced as Miles Warren in 1965 and as the Jackal in 1974. At first, his cloning experiments felt more like outlandish science fiction than a serious threat to Peter Parker’s world.
The Jackal changed dramatically with the now-infamous Clone Saga, when his obsession with cloning erupted into one of Spider-Man’s most psychologically devastating storylines. Miles Warren’s cloning technology has forced Peter Parker, Ben Reilly, and Kaine to question their sense of self to this day. Though he has since faded back into obscurity, the Jackal’s creations still haunt Spider-Man.
Varnae
Varnae Kicked Off A Chain Reaction That Still Affects The Whole Marvel Universe
Blade reveals himself to be Varnae, the first vampire
Varnae was long regarded as an ancient relic of Marvel’s supernatural lore. Marvel’s first vampire had historical influence as Dracula’s predecessor and the origin of vampirism itself. However, he had been long dead and irrelevant in modern times, until very recently.
In 2024, Varnae came back from the dead and reclaimed his mantle as the Lord of Vampires. Possessing Blade’s body, he sparked Blood Hunt, a global nightmare in which vampires attempted to conquer the world. Varnae’s power reached unprecedented levels, leading Doctor Strange to transfer his Sorcerer Supreme power to Doctor Doom, who vanquished Varnae but kept all magical power to himself. Hence, Varnae’s return endangered the whole world twice in a row.
The Maker
Reed Richards Went From Alternate-Universe Hero To Multiversal Supervillain
The Maker fights Wolverine and Spider-Man in Ultimate Endgame
Like most Reeds in the multiverse, Earth-1610’s Reed Richards was an introspective, compassionate prodigy and a loving husband. Once incursions threatened his universe, Reed devolved into a villain with a savior complex and left his Fantastic Four days behind. Few expected that the shy scientist would evolve into one of Marvel’s most dangerous villains.
Freed from morality and driven by his cold intellect, the Maker transcended his world’s boundaries. After the events of Secret Wars, Reed Richards tinkered with Earth-6160 to create an entire universe molded to his image. There, he became both god and devil as the architect of the new Ultimate Universe. As the Ultimate Universe heads to its Endgame, the Maker is bound to be a bigger villain to Earth-6160 than Thanos, Galactus, and Annihilus have ever been to Earth-616.
Revelation
Doug Ramsey Went From Harmless X-Man To Marvel’s New Apocalypse
Doug Ramsey smiles as Revelation in front of Apocalypse’s face
For most of his history, Doug Ramsey a.k.a. Cypher was among the least imposing X-Men. His gift for understanding and translating languages made him invaluable in diplomacy but nearly useless in combat. Doug was the quintessential support character; intellectually gifted, but powerless in combat.
Cypher became essential to mutantkind during the Krakoan era, during which he joined the Quiet Council. Unfortunately, the mutant utopia collapsed soon after. In the aftermath, Cypher inherited Apocalypse’s mantle and forged a new era of terror under the name Revelation. The Age of Revelation has seen the decimation of human populations and reshaped Earth into a genetic nightmare. In this dystopia, many famous heroes and villains owe their current tragedies to Revelation’s rise to power.
The Hood
Parker Robbins Went From Street-Level Criminal To Top-Tier Supervillain
Parker Robbins aka the Hood wields two guns in front of a portal
The Hood seemed destined for obscurity when he debuted. Parker Robbins started out as a petty thief with a gun and a magical cloak, and his early crimes barely registered beyond New York’s underworld. The Hood’s encounters with street-level heroes painted him as another mid-tier crook out of his depth.
Surprisingly, the Hood quietly joined the highest ranks of villainy. Through deals with Dormammu and alliances with the Cabal, the Hood has dealt with beings as powerful as the Void and Chthon, participated in the Siege of Asgard, and helped decide the fate of entire universes that faced incursions. Parker Robbins has even bonded with Zarathos to become Ghost Rider.
Grim Reaper
Eric Williams Suddenly Became The Visions’ Worst Nightmare
A wounded Grim Reaper wields his scythe in realistic Marvel art
The Grim Reaper was originally a product of Marvel’s campier years. A villain wielding a scythe-shaped weapon and dressing like the personification of death seems like yet another gimmicky, pop-culture-inspired antagonist from the Silver Age. Eric Williams’ resentment toward his brother Wonder Man helped him stand out, but his powers were limited and inconsistent. For decades, the Grim Reaper occupied the middle tier of Avengers villains.
Tom King’s Vision series completely redefined the Grim Reaper. Eric Williams’ brutal murder of Vision’s synthezoid children marked one of the darkest comic book moments of the 2010s and transformed him from a cartoonish antagonist into a figure of raw, personal horror. Since then, the Grim Reaper’s descent has only deepened, fueled by demonic alliances with Mephisto and Shuma-Gorath aka Gargantos, who have challeneled their demonic energy through him.
Kraven the Hunter

For years, Kraven the Hunter was regarded as the least intimidating member of the Sinister Six. After all, Sergei Kravinoff is a trophy-obsessed hunter who relies on potions, regular weapons, and brute strength. Among Spider-Man’s foes, Kraven’s outdated theatrics are overshadowed by Doctor Octopus’ tentacles and Green Goblin’s glider.
Then came Kraven’s Last Hunt. In the acclaimed 1987 storyline, Kraven seemingly killed Spider-Man, buried him, and assumed his mantle to prove his superiority. Kraven’s Last Hunt exposed a cunning assassin and a broken man driven by existential despair underneath the lion vest. Since then, it has been clear that Kraven is capable of hunting targets as powerful as Spider-Man, Beast, and even Black Panther, if only he could control his self-destructive psyche.
Mysterio
Mysterio Wiped Out The X-Men Through Sheer Manipulation
Mysterio Reveals His Trick to Wolverine in Old Man Logan Comic Art
Mysterio is an even more absurd villain than Kraven. Quentin Beck possesses no powers or combat skills, as he’s a simple stuntman turned illusionist whose entire arsenal consists of smoke, mirrors, and special effects. Although he has often used actual magic, his tricks usually rely on illusions.
Using nothing but deception, Mysterio pulled off one of the most devastating tragedies in Marvel history when he kicked off the events of Old Man Logan. Mysterio tricked Wolverine into slaughtering the X-Men with nothing but illusions; a feat that not even X-Men villains as powerful as Apocalypse, Mister Sinister, and the Sentinels have achieved. All strength and power goes out the window if a villain plays their cards right.
Red Hulk
Thaddeus Ross Went From Human Threat To World-Famous Villain (& Hero)
Red Hulk screams surrounded by Doctor Doom’s Doombots
General Thaddeus “Thunderbolt” Ross spent decades as one of Marvel’s most persistent yet powerless villains. Though not an obscure antagonist by any means, Ross has spent most of his life as a stubborn military man obsessed with destroying the Hulk, but not being physically able to do it himself. Ross used to be a symbol of human arrogance clashing with forces beyond human comprehension.
One day, Ross got a taste of what he hated the most. Infused with gamma radiation, Ross gained strength to rival the Hulk’s and a unique ability to emit scorching heat from his body. For a time, Red Hulk became the biggest threat to Hulk and other heroes. Fortunately, Red Hulk has since softened into an anti-hero and occasional Avenger, though his transformation remains one of Marvel’s most shocking ascents from mortal to menace.
Korvac
Michael Korvac Went From A Simple Cyborg To Unstoppable Cosmic Threat
Avengers villain Korvac shows his cosmic form on a purple background
Michael Korvac began as a relatively unremarkable, disgraced human fused with machinery by the alien Badoon. Though brilliant, Korvac lacked the charisma or menace of Marvel’s leading villains, and his early clashes with lesser heroes hardly suggested that he would one day rival cosmic gods. Few characters started with less promise or presence.
Merging with the Power Cosmic, Korvac evolved into a being capable of rewriting reality itself. His intellect expanded to godlike levels, and he gained the ability to manipulate matter, energy, and life across galaxies. Korvac earned a saga of his own and has remained in the top tier of powerful universe-ranging Marvel villains since then. Korvac recently recreated Battleworld, which puts him on the level of the Beyonder and God Emperor Doom.
