10 Most Controversial Avengers Villains

Marvel’s Avengers have faced countless foes over the decades, but few are as contentious as the ten discussed in this feature. With every villain, Marvel has sought to explore various shades of morality, and these antagonists have often blurred the lines, inciting debate among fans and critics alike. Whether due to their unexpected motives, their transition from villainy to heroism (or vice versa), or the socio-political commentary they embody, these characters have generated a level of controversy that sets them apart from the usual comic book adversary. As we delve into the intricacies of these notable nemeses, we’ll examine why they remain among the most hotly disputed figures in the Avengers’ expansive rogues’ gallery. Here’s our countdown of the 10 most controversial Avengers villains.

Captain America (Hydra)

The 21st century sparked a wave of controversy when Captain America, the revered World War II icon, was revealed as a Hydra member. This unprecedented plot twist resulted in a severe backlash from fans who felt the shift contradicted Captain America’s symbolic embodiment of democracy and inclusion, core values established by Jack Kirby and Joe Simon. This saga, Secret Empire, saw the emergence of a dark alter ego, Captain Hydra, a villainous version of the superhero. Marvel faced accusations of cheap gimmickry, further fueling the controversy. This narrative thread stretched over a year, culminating in the revelation that the true Captain America had been imprisoned within Kobik’s mind, an ending that left many fans bewildered and disappointed. The storyline, while audacious, was widely deemed an affront to the character’s integrity.

Marcus Immortus

A distastefully controversial story unfolded when Ms. Marvel, Carol Danvers, rapidly birthed a child who turned out to be Marcus Immortus. The villain admitted to kidnapping and manipulating Carol’s emotions to win her over using his father’s machinery. Bizarrely, Carol joined him in Limbo, an act endorsed by the Avengers, causing a stir in the comic world. Marcus, Kang the Conqueror’s son, proved controversial for his actions and implications, his initial appearance being an unsettling tale of mind control and manipulation. It marred the reputations of the Avengers who allowed these deeds to pass unchallenged. Even subsequent remedial attempts couldn’t fully rectify the inappropriate narrative around this problematic character. This saga stands as an unfortunate blemish in Marvel’s history.

The Blob

The Ultimate comics line ignited a firestorm of controversy when villain Magneto inverted Earth’s magnetic poles in the crossover event “Ultimatum”. However, the sequence that left an indelible mark and drew immediate backlash was the Blob committing an act of cannibalism on the Wasp. The depiction was so macabre that it shocked readers. Over time, the controversy remained unresolved and the contentious scene is often lambasted as a tasteless attempt to inject violent content. Critics mark this incident as the starting point of the Ultimate universe’s downfall, spiraling towards an eventual cancellation. This sordid spectacle indeed tarnished the reputation of the beloved superhero franchise.

Phantom Rider

Controversy swirled when the Avengers West Coast narrative villainized him, implicating him in the victimization of the stranded Mockingbird during their entrapment in the 19th century. Under the guise of the Phantom Rider, Slade drugged Mockingbird, deluded by a twisted affection. Despite the morally ambiguous circumstances, Mockingbird let the Rider fall to his death, a decision met with condemnation from the Avengers rather than sympathy for her ordeal. This dark narrative twist tainted the heroes’ image and sparked a heated debate among fans, adding a controversial chapter to the Avengers’ history.

The Commissar

In an outdated story that problematically portrays Asian villagers and their communist leaders. Their archaic attire and settlement starkly contrast the advanced Communist officers. Though it does better than previous tales featuring Asian adversaries, the text inaccurately places Sin-Cong in Central Asia, where people wouldn’t resemble Chinese or Southeast Asians. This incongruity makes this Avengers narrative embarrassingly dated when viewed today.

Baron Blood

Baron Blood, a unique adversary of Captain America, weaves together the chilling lore of vampirism with the historical backdrop of World War II. Operating as a Nazi collaborator, his undead nature allowed him to resurrect time and again, presenting a recurrent threat. Yet, his character is more than a mere supernatural menace; part of Blood’s thematic significance stems from his inhuman nature aligning with the grotesque principles of Nazism. This intricacy sets him apart from run-of-the-mill villains, adding a layer of complexity to his character. However, despite his engaging persona, translating Baron Blood faithfully into other mediums may present challenges, potentially risking the dilution of his profound thematic resonance.



The Marvel mutant unaffiliated with the X-Men, possesses the ability to sway women using pheromones. However, he showed no solidarity with other mutants, choosing to exploit his power through a series of sexually charged conquests. Mandrill represents a repugnant figure of misogyny, racism, and sexual abuse, using his abilities to manipulate women. While Marvel has addressed mature themes before, including a baboon-faced sexual predator undermines any earnest attempts to handle these issues with the gravity they demand.

Scarlet Witch

VisionQuest and subsequent issues subjected the Scarlet Witch to intense trauma, amplified in Avengers Disassembled where her grief-triggered power surge reached near-omnipotence, rewriting reality in House of M. At House of M’s conclusion, she uttered the infamous phrase, “No more mutants,” a reality warp with lingering effects until she reversed it years later. Throughout these events, the Scarlet Witch remained a complex character, her portrayal varying significantly depending on the writer, reflecting her profound flaws and mixed outcomes.



Initially introduced as straightforward small villain, later became notorious for his heinous acts. Transformed into a human bomb by Kree experiments, Robert Hunter, an electrical engineer, fought original Captain Marvel, Iron Man, Spider-Man, and Silver Surfer. His infamous deeds include detonating an elementary school, sparking the events of Civil War, and giving Mar-Vell cancer. These dark milestones elevated Nitro’s sinister and controversial legacy in the Marvel Universe.

Ghaur, a principal Deviant priest, originates from distinct parts of the Marvel Universe to stand as a contentious villain. Exhibiting his exceptional manipulative skills, he clashed with the West Coast Avengers, posed a threat to Wakanda, and even appropriated the purloined power of a Celestial. Though not innately problematic as a villain, Ghaur’s identity as a Deviant inevitably ties him to the Eternals. Furthermore, his actions and inherent traits have fueled controversy, securing his place among the most disputed villains in the Marvel Universe.
