View this post on Instagram Instagram PostThe marketing campaign has been hinting at a cliffhanger ending in which the villain wins the day. Much like Avengers: Infinity War, Doomsday could end with Doom getting his way. The D23 Expo trailer revealed that Victor von Doom lost everything.Leaks have suggested that Doom loses his family to an incursion in the movie. Thus, much like Thanos in Infinity War, we will be given a sympathetic villain.Doomsday, which has been described as the beginning of the end of Marvel's Multiverse Saga, could end with Doom rewriting reality to his liking by creating the Battleworld. Except for a small band of survivors, everyone would probably forget the Marvel Multiverse from before Battleworld.Leaks have suggested that Doom would rewrite reality in a way where he is married to Sue Storm. This is something that happened in the 2015 Secret Wars event, a storyline the Russo Brothers expressed a desire to adapt in the past. Thus, it wouldn't be surprising if the director duo would adapt the 2015 comic for the upcoming two Avengers movies."'Avengers: Doomsday' follows beloved heroes from three distinct universes as they’re set on a deadly collision course and face an existential threat unlike anything they’ve ever encountered."Avengers: Doomsday releases in theaters on December 18, 2026.
