Russos call Doomsday clips 'stories' as fans tie trailers to Endgame timestamps

Collider reports Anthony and Joe Russo posted on Instagram that "What you've been watching for the last four weeks...are not teasers. Or Trailers. They are stories. They are clues...pay attention." Marvel released four trailers ahead of Avatar: Fire and Ash that each focused on unexpected characters — Steve Rogers, Thor, the X‑Men led by Cyclops, and Wakanda confronting the Fantastic Four.

Fans and a Reddit thread have dissected the clips and noted that before each countdown clock a timestamp appears to match specific scenes in Avengers: Endgame. The Steve Rogers clip aligns with the Ancient One warning Bruce Banner about splitting the timeline; the Thor clip matches Loki taking the Tesseract; the Wakanda/Fantastic Four clip links to the Avengers testing the Quantum Tunnel; and the X‑Men clip corresponds to Thor and Rocket in the Thor: The Dark World timeline, where Rocket asks, "Are you crying?" Supporters of the theory say these clues point to Endgame's time travel triggering Incursions that could drive Doomsday's story, and some fans have also connected the clues to plot points in Deadpool & Wolverine.

Observers further note the trailers' countdowns echo Jonathan Hickman's "Time Runs Out" comic arc about the Final Incursion, and the studio's own YouTube countdown reinforces the motif. While the connection between Doomsday and Endgame hasn't been fully confirmed, Endgame's re‑release ahead of Doomsday was flagged as suggestive.
