Reality check: While the world is saved by Marvel heroes most of the time, it’s really the villains who make the whole thing worth watching. They are the ones annihilating the world, shattering our hearts, and giving us the kind of scenes we will never forget. Whether a purple Titan shrinking the whole universe in half or a trickster god, the personification of betrayal, the MCU scoundrels are the coolest. So as a nod to all things sly, here’s my top 10 countdown of the greatest MCU villains—reverse order, of course, because suspense is more enjoyable that way.
10. Mysterio (Jake Gyllenhaal)
Jake Gyllenhaal makes Quentin Beck a master manipulator sustained on smoke, mirrors, and lies in Spider-Man: Far From Home. One moment, he is Peter Parker’s worshipful mentor, the next, spinning elaborate deceptions simply to topple him. Gyllenhaal goes all in with wild abandon—his fake pretension unraveling into outright madness. The twist? We’re just as readily deceived by his fantasies as Peter.
9. The High Evolutionary (Chukwudi Iwuji)
Guardians of the Galaxy Vol. 3 brought us a villain with no redeeming virtues, and that is exactly why he succeeds. High Evolutionary, played by Chukwudi Iwuji, is not just a scientist—he’s a god-complexed dictator with a compulsion to recreate life in his “ideal” image. Heartless, heartless, and dripping with condescension, he’s a villain whom you can’t help but wish to fail. His twisted experiments make him one of the darkest characters the MCU has ever produced.
8. Valentina Allegra de Fontaine (Julia Louis-Dreyfus)
In comes Julia Louis-Dreyfus, smiling her way through the MCU in the guise of Valentina. She doesn’t destroy worlds or fight gods—she’s got power in manipulation. Witty and sarcastic and always with one finger on the pulse, Val plays the long game, moving pieces from behind the scenes while everyone else runs around like lunatics. She’s an exemplar of how the most deadly people don’t need superpowers at all—merely enough charm and malevolence.
7. Killmonger (Michael B. Jordan)
Michael B. Jordan’s Erik Killmonger in Black Panther is more than a villain—tonally, he’s the tragic antithesis of T’Challa. His anger and pain are plausible, his grievances fair, and his deeds atrocious. Jordan delivers a powerhouse performance that leaves you measuring the justice of his grievance, even as you’re shocked by his brutality. Killmonger is proof that the best MCU villains are those who tread the fine line between good and evil.
6. Zemo (Daniel Brühl)
Someone else can do the super strength—Daniel Brühl’s Helmut Zemo keeps the Avengers in check with stealth, strategy, and a sheer vendetta. In Captain America: Civil War, Zemo exposes the cracks in Earth’s greatest heroes and waits to see them explode. He is smart, strategic, and very human, and that is what makes him so scary. Occasionally, brainpower does win out over brawn.
5. Vulture (Michael Keaton)
Adrian Toomes is as ordinary as MCU bad guys get—literally. Michael Keaton plays him as a blue-collar guy who commits evil not for glory, but simply to survive the day. In Spider-Man: Homecoming, his resentment of the wealthy (and the Avengers) is bitter and real, even when he dons high-tech wings to wreak havoc. Keaton brings menace, sarcasm, and desperation to Toomes, and makes him one of Spidey’s most complex foes.
4. Scarlet Witch (Elizabeth Olsen)
Wanda Maximoff’s return in Doctor Strange in the Multiverse of Madness is one of the MCU’s most shocking flips. Elizabeth Olsen turns a treasured Avenger into a tormented villain, and the result is heartbreaking and terrifying, both at once. Wanda’s collapse isn’t so much about power—it’s about loss, obsession, and what occurs when pain obscures sense. Few characters are as tragic—or as frightening—as deranged Scarlet Witch.
3. Green Goblin (Willem Dafoe)
Willem Dafoe’s Norman Osborn bursts onto the MCU with Spider-Man: No Way Home and steals every scene he appears in. No worthy quest or villainous scheme in store here—just flat-out, unadulterated evil. Dafoe’s delivery is so out-there, it’s almost trancelike, and his ability to switch between kindly Norman and crazy Goblin is frightening. Occasionally, all a villain needs to get ahead is someone who enjoys being bad.
2. Thanos (Josh Brolin)
With all the build-up, the MCU’s mastermind villain did not disappoint. Josh Brolin’s Thanos is not only a force of brute strength—he’s a gullible villain. His half-life eradication plan is chilling, but infuriatingly rational in his own warped mind. With intense calm and monomaniacal focus on his purpose, Thanos stamped his presence on the MCU so gigantic that it took all the Avengers (and a couple of spares) to take him down.
1. Loki (Tom Hiddleston)
Who else could top the list? Tom Hiddleston’s Loki is everything a great villain should be—charismatic, witty, unpredictable, and endlessly entertaining. He’s betrayed, schemed, and conquered his way through the MCU, yet somehow remains a fan favorite. Loki’s arc, from jealous prince to anti-hero (and sometimes back again), is one of the richest stories Marvel has told. Mischief has never looked this good.
And that is that—the MCU’s best villains, from strategists to giants, all stand in remembrance. Not a fan of this list? Well, perhaps that is just the villain within you speaking.
