The recent Avengers: Doomsday teaser has sent shockwaves through the MCU fandom, and for good reason. Chris Evans’ return as Steve Rogers has raised crucial questions about which version of the character fans will see in the upcoming film. After analyzing the trailer extensively, we now have compelling evidence that Steve Rogers will appear as a younger version pulled from the past—a timeline-bending plot device that could reshape the entire MCU moving forward.
In Avengers: Endgame, Steve Rogers made a controversial decision to return the Infinity Stones to their original timelines. According to Marvel’s multiverse rules, returning the stones would erase the changes caused by their theft, essentially “pruning” the timelines that resulted from their removal—much like the TVA’s operations in Loki. This explains how Steve could reappear in Doomsday: the Avengers will pull a younger version of Steve Rogers from the past before he traveled through time in Endgame.
The Doomsday teaser shows Steve wielding a shield alongside borrowed artifacts from other heroes. Most notably, he’s seen holding Mjolnir, suggesting he’s accessing Time Vault technology to arm himself with reality-bending weaponry. The dialogue between Steve and Bruce Banner is particularly revealing: “Don’t worry, Bruce. All the power we’re assembling is secured.” This confirms the Avengers are assembling multiversal artifacts to combat Doctor Doom.
There’s an inherent contradiction in MCU time travel logic. In Endgame, Hulk explicitly states that “the past doesn’t change the future.” However, removing Infinity Stones should create branching timelines. The TVA’s pruning would erase those timelines, but Steve might be an exception if the Avengers extracted him before pruning occurred.
Alternatively, Steve spent his entire life in the past with Peggy Carter, aging naturally in an alternate timeline. If this Steve avoided TVA pruning—perhaps protected by Kang—he could exist independently and be retrieved by the Avengers. This would explain his appearance: younger but still having lived decades in another timeline.
A fascinating element of the Doomsday teaser is the apparent conflict between Sam Wilson’s Captain America and Steve Rogers’ return. At the end of Endgame, Sam accepted the mantle and the shield. Now, with Steve returning, questions arise about ownership and role.
In one interpretation, the shield is revealed to have always belonged to Steve—a temporal causality loop reminiscent of Back to the Future. Steve fights in Doomsday and Secret Wars, ultimately gives the shield to Sam in that timeline, which loops back to create Endgame’s circumstances. Like Marty McFly and Chuck Berry, the shield has always been Steve’s because it will eventually become Steve’s through this causal loop.
This doesn’t require killing Sam Wilson or removing him as Captain America. Steve could temporarily borrow the shield for coming battles, with Sam willingly handing it over knowing their timelines will converge. The shield could return to Sam after Secret Wars, ensuring both heroes get their moment and both captains coexist in the expanded MCU.
While the Doomsday teaser doesn’t definitively confirm all details, the evidence strongly suggests Chris Evans will return as an alternate, younger version of Steve Rogers extracted from the past. Whether he’s a version who lived a full lifetime with Peggy in another timeline or simply his pre-Endgame self remains to be seen, but the result is the same: the Avengers have found a way to bring back their greatest warrior for their greatest challenge.
The return of Steve Rogers, handled with the emotional and temporal care it deserves, could be the defining moment of the MCU’s next saga. As Doctor Doom threatens reality itself, it’s fitting that the hero who has always protected the timeline’s integrity will return to protect it once more.
