According to a new rumor, a fan-favorite Marvel character will reportedly be allying with the X-Men and fighting the Avengers in Avengers: Doomsday. The upcoming MCU film, launching next year, will see multiple heroes go up against Robert Downey Jr.

While there was plenty of speculation that RDJ would return for the final two Avengers' projects, the surprise was the role change for the beloved actor.

Avengers: Doomsday is set to be the biggest event in the MCU since Avengers: Endgame, but it may have also erased some other Multiverse Saga shows.

Marvel Studios has officially kicked off the marketing for Avengers: Doomsday . The first teaser is out in the wild and is playing before screenings of Avatar: Fire & Ash . But, that hasn’t stopped it

While many assumed the fourth and final Avengers: Doomsday teaser will be a full-on trailer, scooper Daniel Richtman said this won’t be the case. Richtman didn’t elaborate any further, meaning it’s anybody’s guess what the fourth teaser trailer will focus on.

A leaked teaser trailer seemingly reveals that another major Avenger is making their return.

It's been speculated and seen in leaks — but it wasn't until previews for Avengers: Doomsday began showing last night during Avatar: Fire and Ash screenings that it was confirmed: Chris Evans is back as Steve Rogers, and now he's a proud papa.
