Each year since 2021, Marvel has delivered its fans a Christmas present. That year, it was Hawkeye, then in 2022 it was The Guardians of the Galaxy Holiday Special.

In 2023, the studio released the second season of its multiversal animated show What if...? across the festive period, and this year it is releasing that show's third and final run on Disney Plus.

The new episodes will see stories following up on some of its more recent titles such as Agatha All Along and Eternals, while the confusingly titled series finale, What If... What If? is sure to bring things to a close in style.

The eight new episodes of course see Jeffrey Wright return as the show's narrator, The Watcher, alongside Devery Jacobs's Kahhori and Hayley Atwell's Captain Carter, among others.

And speaking of Captain Carter, in an interview with Screen Rant, Marvel TV executive Brad Winderbaum said that for him, the "most interesting" thing about her is "her relationship with the Watcher".

"If I look at What If...? as mostly an anthology, maybe 90% anthology and 10% serialised, there's something about the culmination of each season, and I don't know if you would call it father-daughter energy or siblings or just a best-friend relationship that emerges between those two, but it's very interesting story territory to play with.

"As much as What If...? seasons 1 through 3 do have an arc, it is the Watcher's story of an introverted guy who is happy to watch the world go on as a spectator. He takes a chance, gets out of his comfort zone, and enters the world.

"And that comes at a cost, much of which has to do with Peggy."

In an interview with Marvel.com, director Bryan Andrews also teased "a lot of surprises".

"There's no way people can guess what's coming," he added. "We do get to push genre a little bit. I'm super excited about some of the ones that are coming up. I think everyone's going to nerd out because we get to push.

"And one of them's going to sell a lot of toys. I can say that. One of them for sure is going to sell a ton of toys!"

Andrews also said there's one narrative that "revisits characters from a season 1 episode".

"There is one that there's some continuation a little bit. And that one's turning out to be quite hilarious and we do love it," he said.

But what else do we know about the final season of What If...? Read on to find out more.

The third and final season of What If...? was released on Sunday 22nd December 2024, with new episodes being released each day.

The series finale will therefore be available to stream from Sunday 29th December 2024.

"It's cool," said Andrews on the show finally being released (via Marvel.com)

"It's awesome seeing the crew and every one of the vendors, everyone worked so hard to try to make it what it is.

"So, to finally be out so that people can show their parents, that's what I was working on!"

What If...? season 3 episode titles

The episode titles for What If...? season 3 were confirmed in December 2024. You can find the full list right here, as well as in the announcement video which was posted to the show's social media channels above.

  1. What If... the Hulk Fought the Mech Avengers?
  2. What If... Agatha Went to Hollywood?
  3. What If... the Red Guardian Stopped the Winter Soldier?
  4. What If... Howard the Duck Got Hitched?
  5. What If... the Emergence Destroyed the Earth?
  6. What If... 1872?
  7. What If... the Watcher Disappeared?
  8. What If... What If?

Winderbaum has told The Hollywood Reporter that the show ending now makes sense when seen in the wider context of where the MCU is heading.

He said: "What If…? has always tied into the greater MCU and the Multiverse Saga. And for reasons that will become clear in the next couple of years, this was the right time to culminate the series from a story perspective."

He also said of the season when speaking on The Official Marvel Podcast: "What If…? season 3 feels like the completion of a trilogy. It takes us to places you’d never expect.

"It goes beyond the first two seasons in its exploration of the Multiverse and it pulls in characters that are very unexpected. It has what I think is an extremely moving and fulfilling culmination for Uatu, The Watcher."
