The Avengers: Doomsday teaser hit us with a heartwarming—and massively consequential—image: an aged Steve Rogers, clad in civilian flannel, gently cradling a blond child before suiting up for one last fight. For fans who lived through Endgame’s emotional payoff, this is the confirmation we’ve been waiting for: Steve and Peggy Carter built a life together. But in the Marvel Cinematic Universe, no new face is without deeper meaning. So, who is this mysterious moppet, and could their comic book history give us clues to their role in the impending doom?
Given that Doctor Doom’s first MCU appearance involved him mentoring the reality-warping child Franklin Richards, it’s a safe bet that Steve’s kid isn’t just set dressing. This child is a narrative Chekhov’s gun. While Steve Rogers is famously childless in mainstream Marvel Comics, decades of Variants, alternate realities, and deep-cut stories give us a fascinating roadmap of possibilities.
The Frontrunner: Ian Rogers, AKA Nomad
The most likely inspiration is Ian Rogers, the most prominent “son of Steve” in the comics. His origin is pure comic book madness: created as an experiment by the evil Arnim Zola in the nightmarish Dimension Z, Ian was discovered and rescued by Steve, who raised him as his own in a hostile world.
When they finally escaped, Ian struggled to adapt to a normal life on Earth, eventually forging his own heroic path as Nomad—a mantle Steve himself once used. He fought alongside Sam Wilson’s Captain America and, in one possible future, teamed up with his sister, Ellie Rogers (Steve and Sharon Carter’s daughter).
While the MCU likely won’t adapt the Dimension Z saga, the core concept is perfect: a child raised by Steve, inheriting his values but forging a unique identity. The name “Ian” has a strong, classic ring to it, and the Nomad identity offers a fantastic legacy path outside the Captain America shield. This is the safe, compelling bet that honors Steve’s legacy while creating a new hero for the future.
The Multiversal Mash-Ups: What If… He Had That Kid?
The multiverse means anyone’s possible, and Steve has some truly wild offspring in alternate realities. These are deep-cut deep dives for the truest geeks:
Sarah Rogers (Crusader): Daughter of Steve and a version of Rogue (who was powered by Carol Danvers’ absorbed abilities). She wields both Cap’s shield and Mjolnir. A powerhouse, but a complicated lineage for the MCU.
The Creepy Twins: In What If? Avengers: Disassembled, Steve and Scarlet Witch have unsettling, powerful twins. Given Wanda’s history with chaotic magic and lost children, this feels like a path the MCU has wisely moved past.
James Rogers: From the animated film The Next Avengers, he’s the son of Steve and Black Widow (Natasha Romanoff), leading a team of Avengers’ children. A fun concept, but it sidelines Peggy Carter, the heart of Steve’s MCU ending.
These are thrilling “what if” scenarios, but they feel less likely given the MCU’s clear intention to cement the Steve/Peggy timeline.
The Nuclear Option: The One Adaptation We Hope They Skip
Brace yourselves. In the Ultimate Universe (Earth-1610), Steve Rogers did have a son… who became the Red Skull. This version was conceived with a woman named Gail before Steve went into the ice, raised in secret by the government, and emerged as a psychotic super-soldier who literally skinned his own face to emulate his father’s greatest enemy.
It’s a dark, edgy-for-the-sake-of-it story typical of that universe. While the MCU isn’t afraid of darkness, this nihilistic twist would utterly undermine the earned peace and happiness Endgame gave Steve. We’re 99.9% sure Marvel Studios will avoid this like a vibranium-plated plague.
The Verdict & The Doomsday Connection
So, who’s the baby in the teaser? The smart money is on an original MCU creation, likely named Ian, who blends the inspirational legacy of the comics’ Ian Rogers with the stable, loving upbringing Peggy Carter could provide. This child represents the life Steve fought for—not just a peaceful world, but a personal one.
Their importance in Doomsday could be twofold:
The Emotional Stakes: They are what Steve must protect, raising the personal cost of the conflict to universe-shattering levels.
The Mystical Stakes: Could this child have inherited more than just Steve’s blond hair? Perhaps a latent super-soldier trait, or a connection to the cosmic scales their father helped balance? If Doom is collecting powerful children, the offspring of a man worthy enough to wield Mjolnir is a prime target.
One thing is certain: that brief glimpse of a domestic Steve Rogers has opened a new door in the MCU. Whether this child picks up a shield, a codename, or simply represents the hope their father embodied, they are now a key piece in the battle against Doomsday.
