Doomsday trailer is here, and some fans believe it has a few clues that suggest the film is hiding two Doctor Dooms – and maybe even a cameo from Cillian Murphy.

As is tradition when it comes time for the D23 Expo, footage leaks have been making the rounds online. This year, they include a four-minute trailer for the third film in Sony Pictures Animation’s Spider-Man trilogy, Beyond the Spider-Verse, and a Doctor Doom-centric trailer for Avengers: Doomsday.

Rumours suggest Marvel's Avengers: Doomsday will feature a multiverse in crisis and colliding realities. Doctor Doom reportedly manipulates events, aiming to reshape reality and create Battleworld. Heroes from different groups may initially fight each other before uniting against Doom.

Whispers of one MCU character’s potential appearance in Avengers: Doomsday have surfaced in the fandom. A new rumor suggests that Sylvie from Disney+’s Loki may return in the upcoming installment.
