After a seven-year hiatus, the Avengers will return to the big screen in the Marvel Cinematic Universe’s Avengers: Doomsday. In July 2024, excitement for the film rose when Marvel announced that it would star Robert Downey, Jr., who previously played Tony Stark (a.k.a. Iron Man) in the MCU, as Doctor Doom.

Since Downey Jr.’s casting, viewers have waited anxiously to learn who else would star in the film. Now that the cast has been unveiled in a livestream, viewers can use our guide to discover the biggest Avengers: Doomsday cast reveals and where they can watch these stars’ latest appearances in the MCU on platforms like Disney+ and more.

Top 10 Avengers: Doomsday cast reveals

1. Alan Cumming as Nightcrawler - X2

The presence of several actors from the X-Men series in Avengers: Doomsday was a pleasant surprise. Arguably, the biggest X-Men surprise went to Alan Cumming, who will reprise his role as Kurt Wagner (a.k.a. Nightcrawler) for the first time since X2 in 2003. Cumming made an impression as the blue-skinned teleporting mutant with his show-stealing opening scene infiltrating the White House. Sadly, Cumming did not return for X-Men: The Last Stand. With no teases of his return over the years, many expected X2 would be his sole appearance as Nightcrawler. However, after 23 years, he will don the Nightcrawler costume again for Avengers: Doomsday.

2. Rebecca Romijn as Mystique - X-Men: First Class

Almost as surprising as Cumming’s return was the revelation that Rebecca Romijn would also return as Raven Darkhölme (a.k.a. Mystique). Romijn starred as the shapeshifting mutant in the original X-Men series. Her last starring role as Mystique was in X-Men: The Last Stand, though she also had an uncredited cameo in X-Men: First Class. She brought a physicality and mesmerizing femme fatale vibe to the character, but then the franchise shifted to prequels, and Jennifer Lawrence took over the role. Viewers who missed Romijn’s unique iteration of Mystique will be pleased to learn she’s back in Avengers: Doomsday.

3. Channing Tatum as Gambit - Deadpool & Wolverine

Channing Tatum’s Gambit is one of the newest MCU heroes starring in Avengers: Doomsday, but his history with the franchise makes his presence surprising. Tatum was once set to star in a solo Gambit movie within the X-Men franchise, but Disney ultimately canceled it. Fans bemoaned the cancelation for years and begged to see Tatum as the proud Cajun, card-throwing mutant. Finally, Deadpool & Wolverine delivered and featured Tatum as a Gambit variant in the Void. Considering some multiversal shenanigans were needed to bring him to life, many were uncertain if he’d ever return to the role, but now he’s surprisingly slated for the MCU’s biggest upcoming movie.

4. Sir Ian McKellen as Magneto - X-Men: Days of Future Past

Considering Sir Ian McKellen portrayed such an iconic and influential role as Erik Lehnsherr (a.k.a. Magneto) in the X-Men series, many fans likely never gave up hope that he’d return. Even so, it was a delightful surprise to learn the MCU really was bringing him back for the first time since X-Men: Days of Future Past to star in Avengers: Doomsday. McKellen offered a beautiful iteration of Magneto, capturing both his terrifying and imposing figure as an Omega-level mutant and the more haunted and conflicted side of a man who just wants to be treated as human. Few characters are bound to shake up the MCU as significantly as a mutant of his power and conviction.

5. Tom Hiddleston as Loki - Loki season 2

The announcement that Tom Hiddleston’s Loki was returning for Avengers: Doomsday was both surprising and not. Few characters have had as many resurrections and fake deaths as the trickster god in the MCU. However, Loki season 2 finally seemed to end Hiddleston’s almost 15-year career in the franchise, giving him an ending that felt like closure. Even if it wasn’t the absolute end, he seemed like he’d be tied up for at least a while. Of course, Avengers: Doomsday found a way to bring him back, successfully surprising fans for the umpteenth time with Loki’s return.

6. The Thunderbolts team - Thunderbolts*

Although Thunderbolts* hasn’t premiered yet, almost the entire lead team, including Florence Pugh’s Yelena, David Harbour’s Red Guardian, Sebastian Stan’s Winter Soldier, Wyatt Russell’s U.S. Agent, and newcomer Lewis Pullman’s Sentry, is slated to return in Avengers: Doomsday. Considering the team is fresh and uniquely made up of anti-heroes, their speedy return in the next Avengers movie is quite surprising. Additionally, with Sentry being one of the most powerful beings in Marvel, having him appear alongside the likes of Magneto and Doctor Doom promises a power overload in Avengers: Doomsday.

7. Tenoch Huerta as Namor - Black Panther: Wakanda Forever

After his explosive debut in Black Panther: Wakanda Forever, viewers expected Tenoch Huerta would someday return as the water-breathing, mutant hybrid Namor, but they didn’t know when. As the leader of the Talokan, Namor clashed with the Wakandans before reaching a shaky alliance. However, it appears Avengers: Doomsday is going global, involving not just the Wakandans but even Namor and, presumably, his Talokan. Namor is incredibly powerful and boasts some of the most unique capabilities in the MCU, making it interesting to see if he’ll be an ally or a foe in Avengers: Doomsday.

8. James Marsden as Cyclops - X-Men: The Last Stand

Aside from a cameo in X-Men: Days of Future Past, the last time viewers saw James Marsden as Scott Summers (a.k.a. Cyclops) was X-Men: The Last Stand nearly two decades ago. Marsden looked the part of Cyclops to a T and perfectly embodied his morality and tendency to walk the straight and narrow. However, he was largely sidelined during the X-Men series before being recast in the prequel series. While there have been no hints of his return in the MCU, he’s arguably the X-Men character most in need of a better ending, making it surprising but also satisfying that he’s returning in Avengers: Doomsday.

9. Sir Patrick Stewart - Professor X - Doctor Strange in the Multiverse of Madness

Viewers aren’t just getting Magneto in Avengers: Doomsday; they’re getting a reunion between Magneto and Sir Patrick Stewart’s Charles Xavier (a.k.a. Professor X), two of the most powerful mutants with the most complicated friendship in the MCU. While Professor X’s presence in Avengers: Doomsday is slightly surprising, the MCU has hinted at his comeback. He last appeared as a variant of Professor X in a cameo in Doctor Strange in the Multiverse of Madness, where he’s part of the Illuminati. Between Logan and the Doctor Strange sequel, Stewart is the one X-Men member who never really left the MCU, meaning Avengers: Doomsday confirmed viewers’ suspicions that the franchise wasn’t done with him.

10. Kelsey Grammer as Beast - The Marvels

In X-Men: The Last Stand, Kelsey Grammer debuted as Hank McCoy (a.k.a. Beast). He was practically the perfect iteration of the mutant. Grammer boasted the physique necessary for McCoy’s beastly appearance and the voice and ability to reflect his distinguished and brilliant persona. Sadly, his role in the X-Men series was relatively minimal. However, in 2022, the MCU shocked fans when it abruptly featured Beast in a parallel universe in the mid-credits scene of The Marvels. Although it spoiled the fact that the MCU was testing the waters for his return, it was still a relief to learn his official return will come soon in Avengers: Doomsday.

Other major Avengers: Doomsday cast

While the ten names above mark the biggest surprises, there are a few other major names in Avengers: Doomsday. As anticipated, one of the last remaining original Avengers is returning: Chris Hemsworth’s Thor. Of course, the MCU’s new Captain America (Anthony Mackie) and new Black Panther (Letitia Wright) will return, alongside their associates Falcon (Danny Ramirez) and M’Baku (Winston Duke). Newer MCU heroes Ant-Man (Paul Rudd) and Shang-Chi (Simu Liu) will also return. Lastly, as Doctor Doom’s presence strongly hinted at, the MCU’s complete Fantastic Four–Pedro Pascal, Vanessa Kirby, Ebon Moss-Bachrach, and Joseph Quinn–will be there.
