Note: This post contains potential spoilers for Marvel’s Avengers: Doomsday.
After Thor, Vision, Steve Rogers, and Lady Thor, a new character will wield Mjolnir in the MCU, and we will see this in the upcoming Marvel film Avengers: Doomsday.
According to insider James Mack, a new character will reportedly wield Mjolnir in a fight against Doctor Doom in Avengers: Doomsday. It will not be Thor or Steve Rogers. It is confirmed that Loki will use Mjolnir in Doomsday.

Mack said, “I heard that another character will lift Mjolnir in a fight against Doom in Avengers: Doomsday, besides Steve Rogers (obviously excluding Thor).”
In a recent Happy Sad Confused interview, Tom Hiddleston teased that he was able to do things with Loki that he hasn’t explored before in Avengers: Doomsday.
Hiddleston said, “The last time we saw him [Loki], he was sitting on the throne. What will happen next… you’ll have to wait and see.”
We already reported that a team has been assembled by the TVA to protect Loki in Doomsday, as Doctor Doom is trying to steal his powers. Deadpool, Wolverine, and Laura Kinney (X-23) will be part of the team, along with some What If…? characters and variants thrown into the Void.
Speaking to GQ Magazine, Hiddleston said Avengers: Doomsday is a “monumental” film.
“My contribution has been completed. It is monumental. The center of the story is absolutely brilliant and was so surprising when I read it. It has never been done before.”
In Avengers: Doomsday, the MCU begins the beginning of the end. As the multiverse nears total collapse, the Avengers assemble to face their greatest challenge yet—incursions, catastrophic collisions between realities that could destroy the entire multiverse. Earth’s Mightiest Heroes must race against time to save their reality while confronting the powerful figure behind it all—Victor Von Doom (Downey Jr.).
Directed by the Russo brothers from a screenplay by their longtime collaborator Stephen McFeely and Michael Waldron.
Here’s the plot synopsis for Avengers: Doomsday:
“Doctor Doom has officially arrived on the Marvel Cinematic Universe stage. This villain, a master of cutting-edge science and powerful magic, will unleash a cascading crisis across the multiverse. Marvel’s most iconic actor, Robert Downey Jr., also returns as Doctor Doom!”
