Spoiler warning: This article contains spoilers for Thor: Love And Thunder.
Thor: Love And Thunder establishes Gorr the God Butcher among the evilest villains Thor has faced in the MCU. He kidnaps Asgard’s children and uses them as bait to lure Thor into a cosmic trap. Gorr’s actions prove equally vile in Marvel Comics, but he faces stiff competition from other supervillains in terms of who has done the most harm.
Many villains prove more evil than Gorr the God Butcher in the comics, including Loki, whose mischievous deeds often mask his vile desire for power. Thor faced absolute evil in the form of Thanos, who used the Infinity Stones to wipe away half the universe and then dismiss Thor with a stunning move that proved his utter contempt for life.
The Wrecking Crew
The Wrecking Crew may not possess the cosmic power Gorr does, but their strength and savagery have few peers in the Marvel Universe. The team, including the Wrecker, Bulldozer, Piledriver, and Thunderball, helped destroy Avengers Mansion during a shocking attack in Under Siege, among the best Avengers comic book storylines ever.
In Avengers #274, they prove their evil when they mercilessly attack Hercules, Thor’s teammate and friend. They leave Hercules in a coma, a stunning outcome for such a powerful figure, especially one who once fought Thor to epic stalemates.
Surtur
Surtur plays a destined role in Ragnarok, the Asgardian apocalypse from prophecy, but that doesn’t excuse the fire demon’s evil behavior. Surtur escalates his efforts to destroy Asgard with increasing savagery, eventually forging the Twilight Sword, among the most powerful weapons in the Marvel Universe, to simply wipe out Asgard and its people.
Surtur’s ire spreads beyond Asgard as well. In The Mighty Thor #19, he sets Yggdrasil, the world tree, on fire. He also invades Earth on several occasions, intent to destroy it as well.
The Destroyer
The Destroyer lacks any feeling or individuality, but this only exacerbates its evil. As a sentient suit of Asgardian armor forged by Odin, The Destroyer possesses only the task presented to it and the determination to carry it out no matter the cost. Its lack of agency also exposes The Destroyer to influence from evil beings like Loki.
Loki routinely manipulates The Destroyer into doing his bidding, including attacking Thor. Thor also gives the armor to Galactus, among the most powerful Marvel cosmic beings, who then uses The Destroyer as his herald and scout for worlds to devour.
Mangog
Mangog embodies the hatred of billions, existing only to hurt and punish. From his first appearance in Thor #154 in 1968, Mangog attacks Asgard again and again, seeking only to cause as much destruction as he possibly can. He even goes so far as to try and destroy the entire universe in one fell swoop by drawing the Odinsword from its scabbard.
Virtually invulnerable, Mangog ranks among Thor’s most powerful villains in Marvel Comics. He even survives being thrown into the sun to return and wreak havoc on Asgard once again.
Hela
Hela reigns as the Goddess of Death in the Marvel Universe, and she brings a cruel evil to the role. Hela kills Thor in Thor #186, a brutal act that proves her god-like power. Though he returns thanks to The Silent One, Hela continues to try and claim Thor’s power by engineering circumstances where he would die.
In contrast, she also later cursed Thor to never die in Thor #373. This left him extremely vulnerable though, and his injuries wouldn’t heal, forcing him to step back from using his powers to help others.
Ultron
Ultron ranks among the most powerful Avengers villains in Marvel Comics and his evil evolves with his android body. He plots to destroy the world in key comic storylines and in Age of Ultron, succeeds in taking over the world in an alternate reality. Ultron’s ambition for perfection escalates through the years, going so far as to take over Adam Warlock’s body.
Ultron also captures Mockingbird during her time on the West Coast Avengers and against her will, copies her brain patterns to create an android mate for himself in the form of Alkhema.
Kang The Conqueror
Comic book fans know Kang The Conqueror stops at nothing to rule all of time. That leads him to disregard the lives and entire histories of many people in the past, present, and future. He ultimately conquerors Ravonna Renslayer’s homeworld simply to acquire her advanced technology and routinely tries to conquer the Earth.
Kang’s evil extends to himself in shocking ways. He kills his own variants, which number in the infinite, on many occasions. He also seeks to destroy Immortus, perhaps his most powerful variant, to claim time for himself.
Iron Man
Iron Man and Thor founded the Avengers together and fought side by side in many battles against the worst villains imaginable. Iron Man arguably nominated himself as an evil villain when he cloned Thor without his knowledge and used the clone, Ragnarok, to attack heroes who wouldn’t register with the government during Civil War.
Ragnarok, a cybernetic clone with Thor’s power and skill, unleashed serious damage on the Avengers. Though Hercules ultimately killed him, the clone represents one of Iron Man’s worst deeds in the comics.
Loki
Loki’s evil actions number too many to count in the comics. His lifelong ambition to undermine and even kill his brother led to many awful acts, including turning Thor into a frog in Thor #365, among the best Thor comic books from the 1980s. His evil goes far beyond that comical episode to conspire to destroy Asgard and the Earth.
Loki also created other villains like The Absorbing Man who then went on to create even more violence and destruction in the world. Worst of all, Loki simply refuses to stop, always returning to his evil ways even after seemingly learning his lesson.
Thanos
Thanos executes perhaps the evilest act in Marvel Comics history when he snaps his fingers and erases half the universe in The Infinity Gauntlet. That’s only the beginning, though. Thanos relishes in his power as the surviving superheroes bring the fight to him. He cruelly dispatches Earth’s mightiest heroes, including the Scarlet Witch, in a shocking sequence.
He reserves his evilest act for Thor. Thor and Thanos equal each other in terms of raw strength, but Thanos uses the Gauntlet to turn Thor into glass. He then shatters Thor, killing him with a single stroke.
