Robert Downey Jr. as Victor Von Doom / Doctor Doom

Victor Von Doom is one of the most formidable villains in Marvel history. He’s a scientific genius, a master of technology and sorcery, and ruler of the fictional nation of Latveria. His armored suit only makes him more dangerous, giving him an intimidating mix of brains, magic, and firepower. He also has a bitter rivalry with Reed Richards. With the Fantastic Four joining Doomsday, that dynamic could get interesting very quickly. Robert Downey Jr. takes on this new cast role after spending more than a decade in the Marvel Cinematic Universe (MCU) as Tony Stark / Iron Man.

What are Doctor Doom's powers?

Doom combines advanced technology with magic, so the armor is only part of the problem. In the comics, it lets him fly, generate force fields, and fire concussive blasts. His inventions extend into robotics, dimensional technology, and time travel, and his scientific expertise is rivaled only by his sorcery. We'll have to wait and see which of those abilities make it into Marvel Studios’ Avengers: Doomsday.

The Avengers

Earth’s Mightiest Heroes are assembling again, but the team looks a little different these days.

Chris Evans as Steve Rogers

Before he became Captain America and helped lead the Avengers through some of their biggest battles, Steve Rogers was an undersized World War II volunteer who was transformed into a Super Soldier. Steve is brave, stubbornly principled, and very good at standing up when everyone else thinks the fight is over. His shield may be iconic, but his real strength has always been convincing everyone around him to keep going. Chris Evans returns to the cast as Steve Rogers after playing the character throughout the MCU’s Infinity Saga.

Chris Hemsworth as Thor

Thor is the God of Thunder, an Asgardian warrior and one of the Avengers’ most powerful members. Over the years, he’s battled gods, aliens, killer robots, and one very determined purple warlord. He can summon lightning, wield some extremely impressive weapons, and has saved the universe enough times that you’d think he might have earned a vacation by now. Chris Hemsworth returns as Thor in the Avengers: Doomsday cast, having played the character since his first MCU movie in 2011.

Anthony Mackie as Sam Wilson / Captain America

These days, it’s Sam Wilson carrying the shield as the MCU’s Captain America. He first joined Steve Rogers as the high-flying Falcon before eventually accepting the shield and making the Captain America mantle his own. Sam doesn’t have Super Soldier Serum running through his veins, but he does have military experience, advanced flight gear, and a talent for bringing people together when things get messy. Anthony Mackie has played Sam since Marvel Studios’ Captain America: The Winter Soldier and officially stepped into the Captain America role in Marvel Studios’ Captain America: Brave New World.

Paul Rudd as Scott Lang / Ant-Man

As Ant-Man, Scott Lang wears a suit that lets him shrink to insect size or grow to enormous proportions. He’s also a devoted dad, which has always kept Scott a little more grounded than your average dimension-hopping Avenger. Unfortunately, being grounded gets tricky when your life regularly involves the Quantum Realm. Paul Rudd has played Scott Lang since 2015’s Marvel Studios’ Ant-Man.

Simu Liu as Shang-Chi

Shang-Chi is one of the world’s greatest martial artists and the wielder of the mysterious Ten Rings. His first MCU adventure in 2021 forced him to confront his family history and embrace both his powers and his place in the wider Super Hero world. Simu Liu introduced Shang-Chi in Marvel Studios’ Shang-Chi and The Legend of The Ten Rings.

The Fantastic Four

Marvel’s First Family is joining the party. And considering Doctor Doom’s history with one particular member of the team, their arrival could be especially important.

Pedro Pascal as Reed Richards / Mister Fantastic

Reed Richards is Mister Fantastic, leader of the Fantastic Four, and one of the smartest people in the Marvel universe. His powers allow him to stretch and reshape his body, but Reed’s real specialty is solving impossible scientific problems. That should come in handy when he faces Doctor Doom, another brilliant scientist who considers him a bitter rival. Pedro Pascal introduced this version of Reed in Marvel Studios’ The Fantastic Four: First Steps.

Vanessa Kirby as Sue Storm / Invisible Woman

As the Invisible Woman, Sue Storm is one of the most powerful members of the Fantastic Four. She can disappear from sight and create incredibly strong force fields, which she can use for both protection and attack. Sue is also the emotional center of the Fantastic Four family and often the one keeping everyone else on track. Vanessa Kirby first played Sue in Marvel Studios’ The Fantastic Four: First Steps.

Joseph Quinn as Johnny Storm / Human Torch

Johnny Storm is the Human Torch, Sue’s younger brother, and the Fantastic Four member most likely to make an entrance everyone will notice. He can cover himself in flames, fly, and unleash powerful bursts of heat. He’s confident, impulsive, and usually has considerably more fun with his superpowers than everyone else. Joseph Quinn made his MCU debut as Johnny in Marvel Studios’ The Fantastic Four: First Steps.

Ebon Moss-Bachrach as Ben Grimm / The Thing

Known as the Thing, Ben Grimm is the Fantastic Four’s resident powerhouse and owner of one of the most recognizable battle cries in Marvel: “It’s clobberin’ time!” His rocky transformation gives him enormous strength and durability, but underneath all that stone is a fiercely loyal friend who would do just about anything for his family. Ebon Moss-Bachrach first played Ben in Marvel Studios’ The Fantastic Four: First Steps.

The X-Men

The mutants are here too. And Doomsday is bringing back some very familiar faces from X-Men history into the cast.

Patrick Stewart as Charles Xavier / Professor X

The X-Men’s founder, Charles Xavier, is better known as Professor X and ranks among the world’s most powerful telepaths. His dream is simple, even if achieving it has never been easy: a future where humans and mutants can live together peacefully. He founded Xavier’s School for Gifted Youngsters to give mutants a place to understand their powers and find a community. Patrick Stewart returns to the role he first played in the 2000 film, X-Men.

Ian McKellen as Erik Lehnsherr / Magneto

An old friend, ideological rival, and occasional ally of Professor X, Erik Lehnsherr, better known as Magneto, can manipulate magnetic fields and metal, giving him some seriously formidable powers. While Charles hopes humans and mutants can coexist, Magneto has often been far less optimistic and much more willing to fight humanity to ensure mutant survival. Ian McKellen returns as Magneto after first playing the role in the original X-Men movies.

James Marsden as Scott Summers / Cyclops

One of the X-Men’s most important field leaders, Scott Summers, goes by the name Cyclops. His mutant ability unleashes powerful optic blasts from his eyes, and his distinctive visor helps him control them. Scott is disciplined, tactical, and often the one who tries to keep the team focused when everything around them is falling apart. James Marsden returns to the role he first played in the original X-Men film.

Kelsey Grammer as Hank McCoy / Beast

As Beast, Hank McCoy combines incredible physical strength and agility with a brilliant scientific mind. That combination makes him equally comfortable in a laboratory or a Super Hero battle, although he’d probably prefer everyone settle things with an intelligent conversation first. Kelsey Grammer joins the cast as Beast, a role he previously played in X-Men: The Last Stand.

Alan Cumming as Kurt Wagner / Nightcrawler

With a burst of smoke, Kurt Wagner, also known as Nightcrawler, can teleport from one place to another. His appearance may be striking, but Kurt is generally a kind and deeply compassionate character, which makes the contrast with his dramatic teleporting abilities all the more fun. Alan Cumming returns as Nightcrawler after first playing him in X2: X-Men United.

Rebecca Romijn as Raven Darkholme / Mystique

Able to transform her appearance to mimic other people, Raven Darkholme is the shape-shifting mutant known as Mystique. Her powers make her an extremely effective infiltrator and a very difficult person to keep track of. Rebecca Romijn returns to the role she played throughout the original X-Men movies.

Channing Tatum as Remy LeBeau / Gambit

As the card-slinging mutant Gambit, Remy LeBeau can charge objects with explosive kinetic energy. Playing cards are his signature weapon, because apparently ordinary projectiles just weren’t stylish enough. Gambit is also known for his Cajun roots, smooth confidence, and talent for turning almost anything he touches into something explosive. Channing Tatum finally got to play Gambit in Marvel Studios’ Deadpool & Wolverine and now joins the cast of Marvel Studios’ Avengers: Doomsday.

The New Avengers

They began as a collection of reluctant teammates, antiheroes, and people with troubled pasts in Marvel Studios’ Thunderbolts*. Now, they’re the New Avengers.

Florence Pugh as Yelena Belova

Trained in the Red Room as a Black Widow, Yelena Belova eventually broke free from its control. She’s a highly skilled fighter and assassin, but it’s her dry humor, blunt honesty, and complicated relationship with the Super Hero life that make her stand out. Underneath all the sarcasm, Yelena cares deeply about the people she lets into her circle. Florence Pugh has played Yelena since Marvel Studios’ Black Widow.

Sebastian Stan as Bucky Barnes / The Winter Soldier

Once known as The Winter Soldier, Bucky Barnes has one of the MCU’s more complicated résumés. He started as Steve Rogers’ best friend, was turned into the brainwashed Winter Soldier, escaped HYDRA’s control, and has spent years trying to build a life beyond the things he was forced to do. He also has a cybernetic arm, Super Soldier abilities, and very little patience for nonsense. Sebastian Stan has played Bucky since Marvel Studios’ Captain America: The First Avenger.

Wyatt Russell as John Walker / U.S. Agent

After briefly becoming Captain America and then losing the title, John Walker resurfaced as U.S. Agent. He’s a highly trained soldier enhanced by Super Soldier Serum, but Walker’s temper and determination to prove himself often make him one of the more unpredictable people in the room. Wyatt Russell first played Walker in Marvel Studios’ The Falcon and The Winter Soldier.

David Harbour as Alexei Shostakov / Red Guardian

As Red Guardian, Alexei Shostakov is Russia’s answer to the Super Soldier, at least if you ask him. He’s immensely strong, fiercely protective of his family, and extremely fond of telling people about his glory days. His relationship with Yelena gives the character plenty of heart underneath all the bragging. David Harbour first played Red Guardian in Marvel Studios’ Black Widow.

Hannah John-Kamen as Ava Starr / Ghost

Known as Ghost, Ava Starr can phase through solid objects thanks to a quantum accident that permanently altered her body. Her abilities make her an exceptional stealth operative, but they also come with enormous physical pain. Ava has spent much of her story trying to survive and find stability rather than pursue traditional Super Hero glory. Hannah John-Kamen has played Ghost since Marvel Studios’ Ant-Man and The Wasp.

Lewis Pullman as Bob Reynolds / Sentry

As Sentry, Bob Reynolds has some of the most extraordinary powers of anyone in the New Avengers, but those abilities come with one big catch. After undergoing an experimental procedure, Bob became the immensely powerful Sentry. But his darker alter ego, the Void, is just as powerful and far more destructive. So yes, having Bob around can solve a lot of problems. But it can also create a very big one. Lewis Pullman introduced Bob in Marvel Studios’ Thunderbolts*.

Wakanda

Wakanda’s powerful warriors are joining the action, bringing even more strength to the fight.

Letitia Wright as Shuri / Black Panther

A brilliant Wakandan scientist and inventor, Shuri is also T’Challa’s younger sister. After her brother’s death, Shuri eventually takes up the mantle of Black Panther herself. That gives her the strength and abilities of Wakanda’s protector, on top of the technological genius she already has. Letitia Wright has played Shuri since Marvel Studios’ Black Panther.

Winston Duke as M’Baku

Wakanda’s Jabari tribe looks to M’Baku for leadership, and he’s one of the country’s fiercest warriors.

He began as a rival to T’Challa but grew into a trusted ally of Wakanda’s royal family. Big, imposing, and rarely short on opinions, M’Baku tends to always make his presence known. Winston Duke has played M’Baku since Marvel Studios’ Black Panther.

Other Returning Marvel Cast Members & Characters

Still counting? Good. We’re not finished yet.

Tom Hiddleston as Loki

There’s rarely a dull moment with Loki, Thor’s brother, the God of Mischief, and one of the MCU’s great wild cards. He started as an Avengers villain before gradually becoming something much more complicated. His adventures with the Time Variance Authority eventually put him right at the center of the Multiverse and its tangled timelines. Tom Hiddleston has played Loki since 2011’s Marvel Studios’ Thor and starred in his own Disney+ show, Marvel Studios’ Loki.

Hayley Atwell as Peggy Carter

The early history of S.H.I.E.L.D. owes much to Peggy Carter, a brilliant Strategic Scientific Reserve agent and one of Steve Rogers’ closest allies. She’s resourceful, fearless, and more than capable of holding her own without superpowers, something she proved repeatedly long before the Avengers were around. Hayley Atwell returns as Peggy after playing the character across multiple MCU movies and shows.

Danny Ramirez as Joaquin Torres / Falcon

The Falcon mantle has a new owner in the MCU: Joaquin Torres. A U.S. Air Force officer who first worked alongside Sam Wilson, Joaquin eventually inherited Sam’s old flight gear and stepped into the Falcon role himself. He’s still relatively new to the Super Hero business, but that doesn’t stop him from jumping straight into an Avengers-level crisis. Danny Ramirez has played Joaquin since Marvel Studios’ The Falcon and The Winter Soldier.

Kathryn Newton as Cassie Lang

An ordinary childhood was always a long shot for Cassie Lang, whose dad is Scott Lang. She shares Scott’s desire to help people and has already followed him into the Quantum Realm. Cassie has also begun developing her own Super Hero identity, meaning there may now be two generations of Langs ready to protect the Multiverse. Kathryn Newton first played Cassie in Marvel Studios’ Ant-Man and The Wasp: Quantumania.

More Characters From Avengers: Doomsday

The lineup doesn’t end there. Tenoch Huerta Mejía returns as Namor, joined by Mabel Cadena as his fiercely loyal ally Namora.

Tenoch Huerta Mejía as Namor

Beneath the waves lies a hidden civilization ruled by Namor and fiercely protected from the surface world. He possesses enormous strength, can breathe underwater, and can even fly thanks to the wings on his ankles. Namor’s devotion to his people is absolute, which makes him a powerful ally when your interests align and a terrifying opponent when they don’t. Tenoch Huerta Mejía introduced Namor in Marvel Studios’ Black Panther: Wakanda Forever.

Mabel Cadena as Namora

Among Namor’s most trusted allies is Namora, one of his people’s fiercest warriors. She’s deeply loyal to both Namor and her community and has shown that she’ll fight anyone who threatens them. Mabel Cadena first played Namora in Marvel Studios’ Black Panther: Wakanda Forever.
