Warning: This post contains potential spoilers for Avengers: Doomsday.
Ahead of the first look at Avengers: Doomsday at CinemaCon in Las Vegas this week, official promotional Avengers: Doomsday flyers have been spotted in Japan.
The flyers reveal a brief new synopsis teasing that the film will feature the “largest assembly in history.”
“Robert Downey Jr., who led the Avengers series as Iron Man, makes a shocking return as the villainous scientist Doctor Doom. Familiar heroes like Steve Rogers and Thor are joined by a new generation of heroes, hinting at the largest assembly in history.”


The “new generation” probably refers to Sam Wilson’s team and the New Avengers. The Young Avengers have been rumored, but nothing is confirmed yet.
There is a lot of excitement among fans for the CinemaCon preview of Avengers: Doomsday. Since December and January, Marvel has released four teaser trailers for the film, but Robert Downey Jr.’s Doctor Doom has not yet been revealed. Fans are now eagerly waiting to see the first look at Doctor Doom at CinemaCon.
According to scooper @MyTimeToShineH, “Marvel Studios held a private test screening of the pre-reshoots version of Avengers: Doomsday for Kevin Feige and select staff, and they were very pleased with it. Some even called it the best Marvel movie yet.”
Directed by the Russo brothers from a screenplay by their longtime collaborator Stephen McFeely and Michael Waldron.
