An Avengers: Doomsday fan theory suggests that the Fantastic Four ship in the Thunderbolts* post-credits is related to Doctor Strange 2.

According to a social media user, the Fantastic Four ship in the Thunderbolts* post-credits scene could be from Earth-838. It was shown in Doctor Strange in the Multiverse of Madness.

The hype for the Fantastic Four's MCU debut is growing, and with it comes to the chance to recreate one of the funniest Doctor Strange scenes ever.

The Fantastic Four characters have already been featured in the MCU, with John Krasinski making a cameo as Reed Richards in 2022’s Doctor Strange in the Multiverse of Madness.
