20 Marvel superheroes and villains we want to see in the MCU

In the days since The Infinity Saga concluded in the MCU, we’ve seen more and more stories about the emergence of new heroes in a post-Thanos landscape, including the rise of Ms. Marvel, She-Hulk, Shang-Chi, and other future Avengers. The goal is clearly to expand the universe, and that means it’s a great time to start thinking about Canada’s own Alpha Flight.Created by writer and artist John Byrne and introduced as a Canadian superhero team in the pages of Uncanny X-Men, Alpha Flight has a rich history all its own involving colorful characters like Northstar, Puck, Sasquatch, and their stalwart leader, Guardian. They’ve been through a lot despite taking a back seat to other super-teams in the pages of Marvel Comics, and that long history and deep bench characters could serve a film or a Disney+ series very well. But even if they just show up as supporting players in a future MCU adventure, they’d be welcome additions thanks to the sheer force of personality on the team alone.

It’s pretty clear from shows like Hawkeye, Ms. Marvel, and the upcoming that the MCU is focused on beefing up its roster of younger heroes after years of focusing on a core group of adults. There are, of course, plenty of characters who fit this bill (one of which we’ll get to in a moment), but one of the most exciting is Amadeus Cho. His time in the Marvel Universe is still less than two decades, but in just a few years he’s made a big impact and done a lot of cool stuff.A supergenius Korean-American teenager who gets wrapped up in superhero affairs, Amadeus is best known initially as a sidekick, partnering with heroes like the Hulk and Hercules for his early adventures before eventually becoming a Hulk himself. In his time as the “Totally Awesome Hulk,” Amadeus distinguishes himself as a character who truly loves being big and green and isn’t afraid to flirt as often as possible even while battling supervillains. He’s a blast to read about, he’d fit right into a show like She-Hulk or a film featuring the recently introduced Hercules, and perhaps best of all, he’s highly adaptable. So even if he’s not a Hulk, Amadeus Cho could be one of the MCU’s next great teen heroes. And while he’s reportedly set to debut in the Spider-Man: Freshman Year animated series, a live-action version of the character would be a welcome addition.

Introduced by Stan Lee and Jack Kirby in the pages of Fantastic Four, Annihilus remains one of the most adaptable supervillains in the Marvel Comics playbook. As the ruler of the Negative Zone, he menaces the Fantastic Four from his alternate dimension home, and occasionally breaks through to torment them on their own playing field. That, plus the sporadic appearance of Annihilus cultists worshiping him on Earth, makes him ideal for smaller-scale threats. But of course, if you want to tell a bigger story, Annihilus and the Negative Zone can be scaled up to apocalyptic threat levels. A Negative Zone incursion could spell doom for Earth, of course, which is a great Fantastic Four epic in the making, but it’s also worth remembering that Marvel once dedicated an entire event, Annihilation, to Annihilus and his army. At one point this guy very nearly wiped out the entire universe, so if the Avengers survive Kang, he could be waiting in the wings to face them next.

Not every supervillain can set out to level a city or wipe out trillions of lives across the universe. Sometimes you need the smaller guys to remind you that individual heroes have something worth fighting for too, and sometimes, you just want villains to be more fun. Enter Arcade, the amusement park-themed supervillain who’s battled everyone from Spider-Man to the X-Men with a wide variety of elaborate, often silly death traps. Created in 1978 by the legendary team of Chris Claremont and John Byrne, Arcade often focuses on kidnapping various superheroes and forcing them to play potentially deadly games in his own private amusement park known as Murderworld. The heroes usually escape, of course, cementing Arcade’s place as a B-list villain at best, but that doesn’t make him any less entertaining. Plus, thanks to stories like Avengers Arena, he’s proven that he can be truly deadly when he wants to be, making him more adaptable for any number of stories. Whether he shows up to fight the eventual Young Avengers team or joins up with the Thunderbolts, Arcade’s got a lot to offer, particularly on the Disney+ side of things where his games could take center stage in a streaming series.

Any list of the most-wished-for new MCU additions over the last decade has to include Beta Ray Bill, the alien warrior who won hearts in Asgard when he proved himself worthy of wielding Thor’s hammer and was given his own version of the weapon by none other than Odin the All-Father. Bill’s head was featured on the Grandmaster’s palace in , hinting that he’s out there somewhere, and it’s about time for him to finally make his grand debut.Bill is everything the MCU needs in terms of heroic characters. He’s brave, he’s loyal, he’s often darkly funny, and he carries with him a tragic backstory that adds a layer of depth to everything he does. Plus, he just looks awesome in battle, particularly when he gets to don the cape and the helmet and fight alongside Thor. A fifth Thor film would be a great place to introduce him, but he could also pop up in numerous other cosmic adventures, particularly once an sequel starts to flesh out more of Marvel’s outer space roster. He could even replace Thor when Chris Hemsworth finally decides to hang up the hammer. Just get him out there. It’s long past time.

Though there are a few notable exceptions, the MCU has understandably kept much of its storytelling firmly focused on North America to this point. That’s gradually changing, though, and that means it could soon be time to head across the pond, where Britain has its own decidedly different national heroes. Captain Britain isn’t a soldier endowed with a powerful serum to give him muscles. Instead, he’s a guy imbued with the power of Merlyn (yes, that Merlyn) to defend Britain and her people. That gives him both a cool set of powers and a very extensive mystical backstory with ties to Arthurian myths and other dimensions that look more like magic kingdoms than versions of our world. Plus, like Captain America, Captain Britain is a title that can change hands, shifting from original hero Brian Braddock to his sister Betsy, and even to the Muslim hero Faiza Hussain, who picked up Excalibur (oh yeah, Excalibur’s a part of this too) and became the new Captain Britain at one point. That makes Captain Britain both extremely malleable and a great potential entry point for more fantasy-driven MCU stories. He could be a new Avenger, star in his own series of solo adventures, or all the above, and if the MCU takes on the 2015 version of the Secret Wars event as its movie source material, putting Captain Britain in charge of the Battleground realm of Higher Avalon could be great fun.

Like the Phoenix Force of the X-Men comics, Captain Universe is more entity than single hero, a cosmic force known as the Uni-Power that will possess an individual during a dark time for the universe, transforming that person into “Captain Universe.” That means that several heroes have taken the moniker in Marvel Comics, but among them all, Tamara Devoux is the most interesting for our purposes.Why? Well, Tamara emerged in Avengers comics in the lead-up to the Secret Wars event. An amnesiac woman with very little sense of her own identity, she was chosen by the Uni-Power because she, like the universe at that time, understood what it meant to be broken. She then went on to be a key player in both the Avengers and the all-female team A-Force, as well as an important harbinger of the dark events to come in the multiversal incursions leading up to Secret Wars. That means this particular incarnation of Captain Universe could be an excellent MCU addition in the build-up to Secret Wars, serving as a kind of living embodiment of the strife all of existence is about to face.

Like the Collector and the Grandmaster, Tryco Slatterus (aka the Champion) is one of the immortal “Elders of the Universe” in Marvel Comics, a being with eons of history behind him who’s chosen to spend his endless life battling other warriors across the universe in an effort to prove himself the greatest fighter in all of existence. It’s a pursuit that’s taken him everywhere from the deepest reaches of the cosmos to Madison Square Garden and put him in conflict with everyone from the Thing to the Hulk to his fellow Elders.So, where does he fit into the MCU? Pretty much anywhere. He’s done some work with Thanos’ brother Starfox (introduced in the Eternals film), so he could have a role to play in that character’s future adventures. He could show up and do battle with Bruce Banner or Jennifer Walters, or even eventually face down Ben Grimm (still uncast, but arriving in the new Fantastic Four film) in some future adventure. Because he’s been everywhere and existed forever, the possibilities are endless, and The Champion could inject some drama into just about any story if used properly.

Though the Fantastic Four have been featured in three big-budget films so far, their kids have not, and the MCU could just be the place for the offspring of Mr. Fantastic and the Invisible Woman to make their live-action debut. Why include them in the FF’s upcoming adventures? Well, Franklin Richards is a mutant with enormous power potential that includes the ability to create whole mini universes, while Valeria is a supergenius who Reed Richards suspects will be smarter even than him someday. They’re fun to be around, they add a layer of emotion to the FF’s adventures, but perhaps most importantly, they both play major roles in the 2015 comic book version of Secret Wars. In fact, Franklin’s ability to generate universes is eventually used to rebuild the entire Marvel multiverse in the wake of that event, making him a truly invaluable part of Marvel Comics as it exists right now. Introducing them along with their parents and uncles in the film could pave the way for a lot of interesting MCU stuff going forward.

Like pretty much every hero to carry the Captain Marvel name, Genis-Vell’s comic book story is … complicated at best, which might explain why the MCU hasn’t tried to integrate him into its tapestry just yet. Still, the idea that Mar-Vell (played by Annette Bening in the MCU) had a son who could wield cosmic powers of his own and complicate the life of Carol Danvers (Brie Larson) is an interesting one, particularly when you consider Carol’s complicated relationship with the Kree. With a little streamlining and the right actor, it wouldn’t be hard to imagine Genis-Vell popping up in the further reaches of MCU space, working as both ally and enemy to characters like Carol and the Eternals, depending on what the story requires. He’s one of those characters with the potential to be a fascinating wild card, no matter where you introduce him.

Let’s be clear for a second: Miles Morales doesn’t need the MCU. The ultra-popular alternate universe version of Spider-Man already has his own hit, Oscar-winning franchise with the Spider-Verse series of animated films, and he’s now a video game superstar. But that doesn’t mean the MCU shouldn’t also make use of him. An Afro-Latinx teenager who takes over for his universe’s Peter Parker after that Spider-Man dies, Miles proved so popular that even when Marvel killed the entire line of comics that birthed him, they kept him around and just moved him over to the main universe, where he exists alongside Peter Parker as one of two Spider-Men.It’s a dynamic that’s worked very well, particularly when Miles gets to hang out with teen heroes like Kamala Khan (who just made her own MCU debut), and it could work just as well on the live-action stage. As Tom Holland gets older, introducing another spider-hero who could take over for him when the actor decides it’s time to go makes perfect sense, and Miles’ presence was already hinted at in . We already got three webslingers at once in , so what’s one more?

Though his presence and his world were referenced in , the supervillain known as Mojo has never quite materialized in live-action. When he does, though, he could be the perfect absurd foil for a single hero with the right vibe, or a super-team like the X-Men or the Young Avengers. As master of his own pocket universe known as the “Mojoverse,” Mojo is both extremely dangerous and extremely weird, controlling a world in which his private gladiatorial games are the only approved entertainment. He’s basically a crazy network executive, which would make him fit in well with the vibe of shows like or the ongoing antics of Deadpool. He could even get his own Disney+ series, where various Marvel heroes compete in the Mojoverse while also battling to escape its pull. He’s a very adaptable, yet very distinct, antagonist, and there are lots of places to use his particular brand of weirdness.

Though his presence was teased at the end of , Fox’s take on Marvel’s mutants wrapped up a little too quickly for Mr. Sinister to make his live-action debut. That leaves the MCU and whatever it eventually does with the X-Men. And while Magneto and Apocalypse are tried-and-true X-villains, Sinister deserves his time in the spotlight.He’s a cloning expert with a history of dark genetic experiments, which could make him the perfect villain to introduce an offshoot of humanity with their own strange DNA. He has a major role to play in the 2015 Secret Wars comic book event, which primes him for a presence in the film crossover. And most importantly, he’s just plain fun, like Tim Curry’s Dr. Frank-N-Furter crossed with Dr. Moreau. If Marvel’s hoping to shake up the X-Men for their eventual MCU incarnation, having a villain like Sinister along for the ride could be just what the doctor ordered.

With Dormammu and Baron Mordo already introduced as antagonists for Doctor Strange in the MCU, the villain known as Nightmare seems like the next step in the Master of the Mystic Arts’ trippy odyssey across the darkest dimensions Marvel Comics has to offer. Ruler of the Dream Realm, Nightmare functions as a kind of evil Sandman, imposing his will and his darkest ideas upon sleeping humans, sometimes to dangerous effect.As for how he could work in the MCU… well, we know that Doctor Strange is heading off with Clea to work on the problem of incursions, which seems like a lead-in to Secret Wars. Nightmare could be a major player in some of these incursions, or the powers at Marvel Studios could save him for a more horror-tinged adventure starring, say, Blade, or a new incarnation of Ghost Rider. However he’s used, Nightmare has the potential to be an absolutely terrifying foe, bumping up the horror elements of the MCU to another level for the right audience.

Between characters like Happy Hogan, Everett Ross, and Ned Leeds, the MCU is already home to several key figures whose in-story job is to be a friend and ally to the superheroes without necessarily being superheroes themselves. It’s obvious why these characters are part of the story, but it’s worth noting that the MCU has yet to integrate arguably the most enduring non-superpowered best pal in Marvel Comics: Rick Jones.Introduced as an innocent bystander who would be the only witness to Bruce Banner’s first transformation into the Hulk, Rick Jones eventually became a vital part of Avengers history, integrating himself into Hulk’s story as well as Captain America’s and the rest of the team as a whole. He did what he could to help the heroes along, served as an important witness to Marvel history, and even eventually got powers of his own, all by simply sticking with the action no matter where it led. In terms of the MCU, you could fit him in just about anywhere. It’s just a question of when, how, and who would play one of the most famous sidekicks in Marvel history.

Introducing The Sentry to the Marvel Cinematic Universe would definitely complicate certain things about its timeline and history, but the dramatic hook of the character is just too good to leave off the big-screen forever. A superhero with immense power, Sentry is introduced as a middle-aged guy who suddenly remembers his superheroic past, and when he tries to talk to others about this past, realizes that no one remembers him. He then sets out to uncover the mystery of why all memory of his heroic exploits has been erased from the world, and along the way discovers a shocking secret about his own mind. It’s a great introduction, but perhaps more importantly, it’s a concept that allows Marvel to tell Sentry stories in both the past and the present, reflecting on the hero’s incredible past, then erasing everyone’s memory and starting over in the here and now. There’s so much potential there that, with the right creative team behind it, could be put to great use in the MCU.

Famously used as a joke title for the third Captain America movie for a few minutes before studio head Kevin Feige unveiled Captain America: Civil War, the Serpent Society are far more than a group of gag villains. Though they certainly have the potential for a lot of comedy, the collective of snake-themed characters is also one of the fascinating centerpieces of legendary writer Mark Gruenwald’s decade-long Captain America run, which also netted us ’s John Walker, the Flag Smashers, and the Power Broker. Watching them try to determine how to function as an actual team with a hierarchy and even a pay structure is fascinating and funny, but perhaps more importantly, they actually are quite dangerous when they put their minds to it.The Society could finally be deployed in the MCU soon, thanks to the confirmation that we’re getting a new Captain America film starring Anthony Mackie in the title role. They could join that film, they could fight Bucky Barnes in a Disney+ series, or individual members of the Society could be dropped into everything from She-Hulk to the upcoming Thunderbolts film.

Spider-Woman’s origins are complex, but her place in the Marvel Comics universe is firm and steadfastly entertaining thanks to years of great storytelling. Though the tale of how she got her powers has been modified several times, her story boils down to this: She was the product of experimentation that left her ostracized, ended up working for the wrong people, eventually realized she was wrong, and ended up a superhero.Since then, she’s become best pals with Captain Marvel (thriving in the MCU), joined agencies like S.W.O.R.D. (just getting started in the MCU), and joined teams like the Avengers to further her heroic career, all while carrying on her own solo adventures as a hero with a troubled past and, recently, a new mom. Throwing her into the MCU mix could spice up the next incarnation of the Avengers considerably, even as she gets a new set of animated adventures in the upcoming Spider-Man: Across The Spider-Verse.

We came very close to a live-action a few years back, with Milana Vayntrub in the role, when Marvel Television developed a New Warriors TV series that never saw the light of day. Vayntrub got to voice the character in animated movies and shows despite her live-action stumble, but now that the MCU is entering yet another period of great expansion, it feels like the right time to consider the leap once again.Doreen Green has always been a fun superhero, but recent comics like Unbeatable Squirrel Girl have really amplified exactly what she’s capable of within the wider Marvel Universe. What started as a joke—that Squirrel Girl can beat villains like Doctor Doom and Thanos by overwhelming them with her furry friends—eventually became a complex exploration of a metafictional character which also remained a story full of great jokes. Now that She-Hulk: Attorney At Law is on the verge of giving us almost outright sitcoms in the MCU, and WandaVision played with the format, giving Squirrel Girl a show of her very own in which she gets to make the universe her playground feels like a very logical next step.
