Rumor: Loki to Become Avengers: Doomsday’s MacGuffin—What Does This Mean for the Multiverse?

A new rumor has surfaced that Tom Hiddleston’s Loki may play a pivotal role in Avengers: Doomsday, which could see the God of Mischief at the heart of a race between the Avengers and the formidable villain Doctor Doom. According to internet scooper Alex Perez, the film may revolve around a battle to find Loki first, with the character serving as a key plot device.

During a recent Q&A on The Cosmic Circus Discord in March, Perez shared insights about the potential storyline, suggesting that Loki would be the “MacGuffin” of Avengers: Doomsday. In cinematic terms, a MacGuffin refers to an object, character, or event that drives the narrative forward or motivates characters, often without having any intrinsic importance beyond its effect on the story. Perez explained, “He’ll be our MacGuffin. The race against Doomsday will be a race to see who gets to Loki first.”

Loki’s Multiversal Role

Marvel Studios has kept a tight lid on the official plot of Avengers: Doomsday, but the rumor aligns with growing fan theories that Loki will be central to the film’s events. Following the conclusion of Loki Season 2, where Hiddleston’s character takes on the mantle of protector of the multiverse, it’s easy to imagine that Loki’s position as the guardian of all realities makes him a crucial figure. With the multiverse now at the forefront of the Marvel Cinematic Universe (MCU), Loki’s actions could have far-reaching consequences for all realities.

One popular theory suggests that Doctor Doom, played by Robert Downey Jr., may embark on a mission to locate Loki in order to control the multiverse. With the power to alter timelines and reality itself, Doom’s quest for Loki could become the driving force of Avengers: Doomsday. This sets up a high-stakes scenario where the Avengers must race against time to find Loki before Doom does, in order to prevent him from wreaking havoc on the multiverse.

A Key Plot Device

Loki’s importance in Avengers: Doomsday could mirror the role of the Infinity Stones in Avengers: Infinity War and Avengers: Endgame. In those films, the Stones were the central motivator for both the heroes and villains. By placing Loki at the center of this cosmic battle, Marvel would elevate the character to a new level of importance, making him not just a mischievous trickster, but a central figure in the fight for reality itself.

While no official confirmation has been given by Marvel, this theory has captured the imagination of many MCU fans, especially given the events of Loki Season 2 and the growing multiversal narrative in the MCU. The idea of Doctor Doom seeking out Loki to harness the power of the multiverse provides an intriguing new layer to the character’s evolution.

What’s Next for Avengers: Doomsday?

Avengers: Doomsday is currently set to hit theaters on May 1, 2026, with Avengers: Secret Wars following just a year later on May 7, 2027. As Marvel continues to build toward these monumental films, it’s likely that more details about Loki’s role and his interactions with the Avengers and Doctor Doom will surface.

Until then, fans are left to speculate on the significance of Loki in Avengers: Doomsday. Will he truly be the key to saving or destroying the multiverse? Only time will tell, but one thing is certain: Loki’s influence in the MCU is far from over.
