The Avengers have gone from the Age of Ultron to the age of the undead.

Marvel’s mightiest superheroes were turned into brain-obsessed living dead in a 2021 episode of the Disney+ animated series What If…, and now the zombification of the Marvel Cinematic Universe continues in the new miniseries, Marvel Zombies.

In a December 2024 interview with Entertainment Weekly, Marvel Television and Animation head Brad Winderbaum spoke about What If…, and how it sets up the next chapter for the nightmare scenario of superheroes being taken over by a zombie outbreak.

“If you remember that zombies episode from season 1, that is very much like the part 1 prologue for this giant, epic event that is coming out next year,” he teased. “It ties right in. It is the same universe.”

So what is Marvel Zombies? Here’s what to know about the new Disney+ streaming animated series, including which actors are returning to voice their MCU characters.

What is Marvel Zombies about?

The new Marvel Zombies show continues the story that began in the episode of the animated series What If…? titled “What If… Zombies?!”

In the What If… episode, a zombie virus from the Quantum Realm infects the Avengers, and eventually much of the Earth’s population, leaving heroes like Spider-Man, Vision and a small group of others fighting against the supernatural superheroes.

According to the official description for Marvel Zombies, as the infected Avengers cause carnage, “a desperate group of survivors discover the key to bringing an end” to the outbreak, “racing across a dystopian landscape and risking life and limb to save their world.”

The concept of undead versions of Marvel characters was originally introduced in a story from the Ultimate Fantastic Four comic book by Mark Millar and Greg Land.

Marvel Zombies launched as its own series in 2005, from The Walking Dead creator Robert Kirkman.

“I love Marvel Comics and I love zombies,” Kirkman told Comic Book Resources that same year. “I couldn’t really pass this up.”

To celebrate 20 years since the Marvel Zombies comic debuted, and the release of the animated miniseries, a new comic, Marvel Zombies: Red Band, will hit store shelves on Sept. 17.

When is the Marvel Zombies release date?

Marvel Zombies will premiere on Sept. 24, just in time to kick off spooky season.

According to Variety, it is the first series from Marvel Studios Animation to be rated TV-MA.

In a March 2024 IGN interview, Winderbaum said, “In terms of more mature animation, yeah, we’re making a Marvel Zombies show right now that is pretty intense that’s for sure a TV-MA show.”

“And again, it’s trying to honor the comics,” he continued. “And what was so great about the comics was it not pulling its punches. That’s certainly what we’re going for on that project also.”

Prior to Marvel Zombies, the most recent animated series from Marvel was Eyes of Wakanda, which debuted Aug. 1 on Disney+.

Is there a trailer for Marvel Zombies?

Yes, a trailer for Marvel Zombies was released on Sept. 2.

The gory preview is filled with gruesome bloody battles, showing Thunderbolts’ Yelena (Florence Pugh) and Red Guardian (David Harbour), fighting zombies with the help of Shang-Chi (Simu Liu). Spider-Man is also up against an army of the undead, using his webs and super strength to slaughter the scary creatures.

The terrifying trailer also gives glimpses of a zombie Captain America, Namor, Scarlet Witch, Thanos and more. According to EW, it also features the MCU debut of Blade Knight (Todd Williams), a version of the vampire hunter Blade, who is now a slayer of zombies.

Who is in the voice cast for Marvel Zombies?

The voice cast for Marvel Zombies features several actors returning to the Marvel Cinematic Universe, including:

• Florence Pugh as Yelena Belova
• David Harbour as Red Guardian
• Simu Liu as Shang-Chi
• Elizabeth Olsen as Scarlet Witch
• Paul Rudd as Ant-Man
• Tessa Thompson as Valkyrie
• Awkwafina as Katy Chen
• Hailee Steinfeld as Hawkeye

How many episodes will Marvel Zombies have?

Marvel Zombies is a four-part miniseries event. All four episodes will drop on Sept. 24.

In an August 2025 Collider interview, creator and showunner Bryan Andrews explained how Marvel Zombies was initially conceived as a movie, but “certain issues” had the creative team split the story into multiple chapters.

“So basically it’s like a four-episode mini-event, like a film broke up into four parts,,” Andrews continued. “It’s one story. It’s one throughline. A lot of insanity happens.”

Where can I watch Marvel Zombies?

Marvel Zombies will be available to stream on Disney+.
