- The first trailer of Avengers: Doomsday introduces us to Steve Rogers, AKA Captain America's child.
- The identity of this child is unknown to us as of now, but it could be Nick or Rick, the son of Steve and Peggy Carter, from a few scattered stories from Marvel comics.
- Avengers: Doomsday is set to release on December 18, 2026.
After a wait that felt like an eternity, we finally have the first trailer for Avengers: Doomsday, and while the clip is short, it features something, or rather someone, whom the fans have been eagerly waiting to return. Now, I’m certain you are already aware of who I’m referring to. The teaser confirms that Steve Rogers will return for Avengers Doomsday, and while this alone is an insanely epic revelation, Marvel was not done with blowing our minds away and revealed that Steve Rogers now has a baby. Now, the big question is, who exactly is Steve Rogers aka Captain America’s kid in Avengers: Doomsday? Does he exist in the comic books? Let’s find out.
Who Is Captain America’s Baby in Avengers: Doomsday?

Now, this question could be rather tricky to answer because in mainstream Marvel Comics, Steve Rogers did not really have children. However, in What If…? storylines, we get to see him have a baby with multiple Marvel characters. In one storyline, he had a baby with Rogue, who became a superhero named Crusader with powers inherited from both her mom and dad.
In another interesting turn of events, Captain America had twins with Natasha Romanoff named James and Sarah Rogers, but since this happened in Avengers Legacies, a non-canonical event, it does not really matter in the bigger picture.
Now, coming to Peggy Carter, in some scattered Marvel stories, Steve Rogers had a child named Rick or Nick with Peggy, and in Avengers: Doomsday, there’s a chance that we could see one of them being the baby Steve is holding in his arms. The anticipation regarding this kid’s identity might just be the biggest question on the internet.
Now, looking at things, this was the first teaser, and the next one will probably feature Thor, as reported by some scoopers, so there’s a good chance that we will have to wait till the movie actually comes out to find out who that kid is.
