How is this happening?! After a week of huge MCU leaks, it appears the X-Men theme from Alan Silvestri's Avengers: Doomsday has somehow managed to find its way online.

Loki's redemption story is some of the best character work in the MCU, and one line from The Avengers likens it to another fantasy journey.

The sudden appearance of a cryptic symbol has added credence to one compelling theory about "Avengers: Doomsday."

Doomsday and Avengers: Secret Wars claims, while a few intriguing new details about Sadie Sink's Spider-Man: Brand New Day role have also surfaced.
