No matter who is carrying the shield and mantle of Captain America – Steve Rogers, Sam Wilson, Bucky Barnes, John Walker (or others) – they face off against the best Captain America villains of all time, including numerous evildoers and war criminals who echo Cap's longevity back to the '40s.
Now, in Captain America: Brave New World, Sam Wilson will take up the mantle of Captain America to face down the Leader and the Red Hulk, two all-time great Marvel villains who are usually foes of the Hulk. But they'll fit in just fine alongside the other schemers and supervillains Cap has squared off with over the years. And of course, classic Cap villain Sidewinder will also make his MCU debut.

Georges Batroc – A.K.A. Batroc the Leaper (created by Stan Lee and Jack Kirby in 1966's Tales of Suspense #75) is a little bit of a joke to some comic fans, but he's also one of the best martial artists in the Marvel Universe – so much so that he's gone toe-to-toe with Captain America time and time again.
And while his plum-and-mustard costume, outlandish facial hair, and oddball accent make him seem like a cartoon, there's no question that Batroc is one of the deadliest mercenaries in Marveldom, even occasionally leading his own team, Batroc’s Brigade.
Batroc has even made it to the MCU, played by appropriately-named French Canadian UFC fighter Georges St. Pierre, with appearances in Captain America: The Winter Soldier, and The Falcon and the Winter Soldier.
9. Secret Empire
The Secret Empire (featured in the original '70s Captain America story of the same name) is a world-conquering organization that tried to bring down the U.S. government by ruining Captain America's reputation and infiltrating the highest levels of government. Their machinations eventually led to one of Steve Rogers' first breaks with his identity as Captain America.
Steve found himself deeply disillusioned with the government when he discovered that Number One, the Secret Empire's leader, was a high-ranking government official – heavily implied to be President Richard Nixon himself – an encounter that lead to Number One committing suicide, and Rogers walking away from the mantle of Captain America for a short time.
This story also put the building blocks in place for Sam Wilson, the Falcon, to become Captain America years later.
8. Crossbones
A disciple of the Red Skull, Crossbones assembled the Skeleton Crew, a team of neo-Nazi villains dedicated to upholding and spreading the Skull’s fascist beliefs with violent fervor as his henchmen.
Though he lacks superpowers, Crossbones' fierce dedication to his dark ideals and his determination have made him a worthy foe for Captain America time and time again, even carrying out the apparent assassination of Steve Rogers after Civil War as he was being brought into a courthouse to stand trial for his actions in Civil War.
Crossbones appeared in several MCU Captain America films, played by Frank Grillo, though his last appearance seems to have come – appropriately – in Captain America: Civil War, in which he carries out a terrorist attack that kills many civilians as well as himself.
7. A.I.M.
Fans of the Marvel Cinematic Universe may know A.I.M. best as the secondary villains from Iron Man 3, and though Advanced Idea Mechanics certainly have a history with the armored Avenger, in comic books, their ties run deeper with Captain America.
A.I.M. are responsible for creating the Cosmic Cube, an artifact of ultimate power that later became a powerful weapon in the hands of Cap's arch-rival the Red Skull.
And not for nothing, A.I.M. is led by M.O.D.O.K. (Mental Organism Designed Only for Killing) a giant psychic floating head, a weird and wild character all on his own who was also adapted into the MCU in Ant-Man and the Wasp: Quantumania – though with some very different origins.
6. Serpent Society
A cadre of snake-themed super-villains may seem a little silly, but it's hard to argue with the villainy the Serpent Society have perpetrated over the years.
Though they started with only a handful of members, the Society grew to encompass a veritable legion of villains who have menaced Captain America for decades.
The Serpent Society’s membership has included everyone from Sidewinder, to Puff Adder, Madame Hydra, Copperhead, and Princess Python, and even Diamondback, who later reformed, becoming a longtime love interest of Steve Rogers.
Serpents are a common theme for Captain America villains too – the Serpent Society was predated by the smaller Serpent Squad, there's also a villainous white supremacist militia called the Sons of the Serpent.
The Society's original leader, Sidewinder, will appear in Captain America: New World Order, played by Giancarlo Esposito.
5. Arnim Zola
Arnim Zola may be one of Captain America's weirdest villains – but he's also one of the most deadly. In his modern form, he's a giant TV screen with arms and legs, but his history is as a Nazi scientist who transferred his consciousness into an artificial body.
While Zola has been responsible for numerous evil schemes over the years, perhaps his most dastardly was creating Dimension Z, an alternate, dystopian reality where Cap raised Zola's son Ian as his own before seemingly losing both Ian and Sharon Carter to Zola's doomsday weapon – all told in the classic story Captain America: Castaway in Dimension Z.
Zola has also appeared in the Captain America films, especially in Captain America: The Winter Soldier, where he is a sentient computer program on a TV screen.
4. Tony Stark
One of Cap's oldest allies – and the man who pulled him from the ice where he was frozen since World War II – may seem like an odd choice for a list of his greatest enemies, but it all comes down to Civil War, a story that pitted the old allies against each other over the Super Human Registration Act.
In Civil War, Cap and Tony went to battle, with the Marvel Universe's heroes picking sides between them. In comic books, it eventually ended with Cap surrendering, an act that allowed Red Skull and his co-conspirators to assassinate him.
Things haven't quite been the same since Cap and Tony since Cap returned, and though they’ve been somewhat uneasy allies, they have also found many more reasons to be at each others' throats in stories in the years since.
3. Hydra
Hydra is a fascist organization dedicated to world domination, which has often been seen as the antithesis of S.H.I.E.L.D. They're also known for their history with Captain America, including his rivalries with Baron Strucker, Madame Hydra, and numerous other villains, stretching all the way back to World War II.
Hydra is well known to fans of the Marvel Cinematic Universe, where the organization were key players in several MCU films, especially Captain America: The Winter Soldier, which revealed Hydra had infiltrated SHIELD.
Perhaps the worst thing Hydra ever did to Captain America in comics was making him their leader, when Red Skull used a Cosmic Cube (that thing we mentioned that A.I.M. invented) to turn Steve Rogers into a Hydra infiltrator and dictator.
2. Baron Zemo
There have been two Barons Zemo to square off with Captain America over the years.
The first, Heinrich Zemo, was a Nazi scientist who was disfigured in a clash with Cap, and who was also indirectly responsible for the seeming death of Cap's partner, Bucky (who was later resurrected as the Winter Soldier). Heinrich later resurfaced when Cap was unfrozen, forming the Masters of Evil, a squad of villains brought together to take on the Avengers in Avengers #6.
The second Baron Zemo, his son Helmut, took over his father's mantle, and the leadership of the Masters of Evil. He even led the Masters in falsely reforming from villainy as the Thunderbolts, before turning back to villainy himself.
Helmut Zemo is played in the MCU by Daniel Bruhl.
1. Red Skull
There's no menace in Captain America’s history more evil, more deadly, and more villainous than the Red Skull. Something of a Nazi equivalent to Captain America as a figurehead and super soldier for the Nazi regime, the Skull has threatened Captain America – and the freedom of the entire world – for decades.
Since World War II, the Red Skull has haunted the free world in some form or another, with the original Red Skull, Johann Schmidt, actually managing to cheat death more than once.
Among his many sins, the Red Skull once used a reality-altering Cosmic Cube to turn Steve Rogers himself into a Hydra spy.
However, the subverted Steve actually killed the Red Skull for what appears to have been the final time (so far). And thankfully, the real Steve Rogers returned.
