‘Avengers: Doomsday’ Plot Details Tease Doom’s ‘Rabum Alal’ Name, Peggy Carter Twist and Hero Goodbyes

Warning: This post contains potential spoilers for Marvel’s Avengers: Doomsday.

Robert Downey Jr.’s Doctor Doom will have multiple Latverian witches and Boris by his side in Avengers: Doomsday.

According to a new rumor, Doctor Doom’s witch followers call him “Rabum Alal,” a name that originated in Jonathan Hickman’s New Avengers (Vol. 3), where it served as Doom’s secret identity after he discovered that the universes were collapsing.

Recently, insider James Mack (via Patreon) shared a few new scoops about Avengers: Doomsday. According to Mack, Chris Evans’ Steve Rogers fights a witch, and when he removes her mask, the witch transforms into Peggy Carter to manipulate him.

Owen Wilson’s Mobius will be involved in a mysterious scene in the third act of Avengers: Doomsday. He is seen staring at a strange rift or portal, where one or more characters may appear.

Before the final battle in Avengers: Doomsday, some Earth-616 heroes will reportedly say goodbye to their loved ones. Scott will say goodbye to Cassie, with Kamala and Kate Bishop by her side.

Directed by Anthony and Joe Russo, Avengers: Doomsday follows beloved heroes from three distinct universes as they are set on a deadly collision course and face an existential threat unlike anything they’ve ever encountered.

Here’s the official description of Doctor Doom in Avengers: Doomsday:

“The fearsome Victor Von Doom (Robert Downey Jr.) is the mysterious and enigmatic monarch of Latveria. Behind his impenetrable mask, he is a master of both sorcery and technology.”
