VisionQuest post-credits scene has huge implications for RDJ in Doomsday after character return

Warning: This article contains spoilers for the VisionQuest post-credits scene

Avengers: Doomsday is just around the corner and the post-credits scene for the Vision-focused Disney+ show VisionQuest showed Dr Doom recruiting yet another major MCU character for the upcoming film.

Marvel’s latest show VisionQuest saw Paul Bettany return as Vision alongside James Spader as Ultron, and the finale has been met with largely positive reviews, including a whopping average score of 9.5/10 on IMDb.

The biggest reveal in the entire TV show however is largely unconnected to the series itself as it instead hinted that Elizabeth Olsen’s Scarlet Witch has been brought back from the dead by Dr Doom.

Doom is set to be played by Robert Downey Jr in Avengers: Doomsday, which is just a month away, but fans online are convinced that the scene confirms ongoing fan theories that he will not be the only actor playing the iconic villain in the film.

Fans are convinced the post-credit scene, which sees Wanda Maximoff brought back from the dead, doesn’t actually feature RDJ as Doom

For those who’ve been out the loop the Maximoff sister was killed at the end of Doctor Strange in the Multiverse of Madness when she sacrificed her life and dropped a huge temple on herself in the process.

It was left fairly vague as to whether she fully died (no body no death remains king in the MCU), however it appears she actually did… for a while.

Doom is shown removing the rubble from on top of her and reviving her, but fans noticed a key detail, with one tweeting: “Who did they have voice Doom in this because that is NOT RDJ.” Other fans have previously noticed that in some of the trailers you can see that the eyes of the face behind Doom’s mask are green, not Downey Junior's brown eyes.

Whilst it’s possible he has contact lenses in, many fans have noticed that this is now yet another scene or teaser for Doomsday in which it doesn’t appear to be RDJ in the costume, and another where the voice sounds completely different to the one in the original trailer (which is very clearly RDJ putting on an Eastern European accent).

This is not the first post-credits scene to tease Doomsday as the Avengers: Endgame Encore post-credits scene had several.

The one that fans are most clearly linking to Wanda’s revival is a scene involving Mark Ruffalo’s Bruce Banner in which he was kidnapped by Doom.

Many fans believe that Doom is taking control of the most powerful heroes in the MCU and turning them to his side, with many believing that Hulk and Wanda will be joined by Benedict Cumberbatch’s Doctor Strange and Sylvie from Loki.

One fan jokingly tweeted Doom’s potential lineup and said: “MAMDANI FOR THE LOVE OF GOD, PLEASE DO SOMETHING !!!”

Another however pointed out that, based on the heroes Doom is collecting in Doomsday, chances are it will have an Infinity War style ending where the Avengers lose to set up Secret Wars.

They said: “There is no possible future where the Avengers come out on top, ever… EVER!! Every single Avenger dies against Doom’s lineup.”

Avengers: Doomsday releases in cinemas 16 December, 2026.
