Avengers: Doomsday looks like a movie packed with secrets behind Doctor Doom, and the one we'll discuss here could even explain why Marvel’s next big villain is so hard to defeat. A recent leak and a series of insider teases have pointed toward a mysterious artifact known as the Word of God.

This Word of God is a book with immense powers that could be part of Doom’s growing collection of weapons. While Marvel hasn't shared any details or confirmed that this book will be Doom's weapon, the details surrounding it circulating online have become hard to ignore.

The biggest reason for the excitement is that the Word of God is not simply another object. In Marvel Comics, it has a connection to science, other dimensions and reality-altering power.

That makes it especially interesting for Doctor Doom, a character whose abilities have always sat between genius and mastery of magic. Still, it does not mean that this book will be Doom's only power against his enemies.

There are rumors that Doom has a whole collection of dangerous objects, and this book could be another 'source of power'. Insider Alex Perez also previously hinted that Doom has collected artifacts over the course of his adventures.

These items help explain why he is so powerful even though he doesn’t have the kind of godhood associated with Loki. That difference could be very important in Avengers: Doomsday, especially if this book really appears in the Marvel movie.

The book named the Word of God gained attention after insider Alex Perez linked Doctor Doom to supernatural elements from WandaVision and Agatha All Along. In a February 2026 Q&A, he said Avengers: Doomsday would explore the Darkhold, runes, and magical power absorption before teasing the mysterious Word of God.

Perez said (via The Cosmic Circus):

"It mainly has to do with the concepts of magic that are explored in those shows. As much as this film is heavily based on the multiverse, time, and science, a good portion of it really goes into exploring the supernatural."

The insider continued:

"The Darkhold, the runes, the way Agatha absorbs magic—it’s all relevant to something Doom does in Avengers: Doomsday. All I can tell you is to beware the man who carries the Word of God."

When asked if Doom would use the Word of God to become more powerful, Perez described him as someone who has gathered many unusual artifacts throughout his adventures. Now that changes how the Doctor Doom's source of power theory should be viewed.

The leak does not claim that Doom will receive all his powers through one object. His intelligence and inventions go beyond a typical villain, and he can use these as a great source of power.

Another clue came from a Hot Toys Doctor Doom figure tied to Avengers: Doomsday which included a "concept-art-inspired magical book." Later, Perez clarified on X that the concepts referred to it as the "Book of God" (not the Darkhold).

If you look into the Marvel comics, the Word of God isn't just an ordinary spellbook. It was created by an extradimensional engineer called the Author and contains much of his power. It holds the power to easily affect reality and help its user travel between dimensions.

What makes it unusual is its mix of science and magic. Although it looks like a magical object, its origins are linked to advanced technology and another dimension. That makes it a natural fit for Doctor Doom, who is both a scientist and a sorcerer.

With great powers come great consequences, and the same is the case with the Word of God, as the book also has dangers. Heavy use can leave a mark on the user and connect them to the Author, while its power can also affect the user's mind and push them toward madness.

The current Avengers: Doomsday leak suggests the Word of God could be one part of Doom's larger collection of powerful objects. It could help him manipulate reality, understand the multiverse, or travel between dimensions. Still, fans should note that the exact role of the book in the upcoming movie is unconfirmed.
