‘Avengers: Doomsday’ Reportedly Connected to ‘Multiverse of Madness’ — Loki to Replace the Beyonder

(WARNING: This post contains potential spoilers for Marvel’s Avengers: Doomsday.)

A new report from an insider has revealed that Marvel’s Avengers: Doomsday is reportedly heavily connected to Doctor Strange in the Multiverse of Madness.

We recently reported that Doctor Doom’s right-hand man in Avengers: Doomsday is reportedly a wizard who can use a sling ring — Doctor Strange. He was corrupted by dark magic following the events of Doctor Strange in the Multiverse of Madness, where he developed a third eye on his forehead. Strange was last seen being recruited by Clea to help stop the incursions.

Loki to Take on the Beyonders’ Role in ‘Avengers: Doomsday,’ Says Insider

According to insider @Cryptic4KQual, Loki will reportedly take over the Beyonders’ role in Avengers: Doomsday.

Scooper Earth 616 revealed that in Jonathan Hickman’s Secret Wars comics, the Beyonders were powerful beings who destroyed the multiverse, and Doctor Doom later stole their power to create Battleworld.

If Loki replaces them, it likely means his power, which is currently holding the timelines together, is what Doom needs. Instead of stealing power from the Beyonders, Doom would take Loki’s cosmic energy, making him the source of Doom’s godlike abilities. Previous reports stated that Loki’s power would be stolen in Doomsday, and this leak explains why he may become the main multiverse power source. If Doom takes Loki’s power, he could reshape reality and build Battleworld from the remains of destroyed universes.

Also, Avengers: Doomsday will reportedly feature alternate versions of the Black Swans.

Directed by the Russo brothers from a screenplay by their longtime collaborator Stephen McFeely and Michael Waldron.
