Fans are scrutinizing the Halloween costumes worn by Robert Downey Jr. and Pedro Pascal, suggesting Pascal's Doctor Doom outfit may contain an Easter egg related to the upcoming Marvel film Avengers: Doomsday. While Downey Jr. appeared in a costume resembling Mister Fantastic, Pascal's Doctor Doom attire, at first glance, seemed simpler, featuring a mask, cape, jeans, and a sweatshirt.

Upon closer examination of the sweatshirt, fans noticed an MIT logo. Some viewers interpret this logo as an illustration depicting both Doctor Doom and Mister Fantastic, potentially teasing a shared past between the characters. This speculation gains traction given that The Fantastic Four: First Steps offered limited insight into Reed Richards and Victor von Doom's relationship prior to Avengers: Doomsday. The film did, however, include a scene that appeared to show Doctor Doom with Franklin Richards.

This detail has fueled theories that Pascal and Downey are hinting at a significant backstory between Reed and Victor that audiences may explore in the upcoming movie. One social media post suggests that the MIT logo specifically represents the characters having attended the university together.

However, not all fans are convinced, with some pointing to the low image quality of the original upload as a reason to avoid over-interpreting the detail. These skeptics suggest the logo might simply be a piece of merchandise. As with many early fan theories surrounding major film releases, the significance of this potential Easter egg remains to be seen.

With Avengers: Doomsday set to premiere on December 18, fans continue to analyze any clues, including a previous Father's Day post by Robert Downey Jr. that some interpreted as hinting at Doctor Doom's tragic backstory.
