Now that we have seen the first full trailer for Avengers: Doomsday, we have a better idea of what will go down in the gigantic event film. There will be some awesome team-ups and throwdowns, and plenty of surprises along the way, but one new rumor claims to reveal the secret lineup of superheroes that will be part of the final fight against Doctor Doom. It’s been rumored that the fight takes place in Latveria, suggesting Doom will unleash an army of Doombots against the Multiverse's Mightiest Heroes. There are rumors that fans may see a second chair reveal happening during Marvel Studios' Hall H panel at Comic-Con this Saturday in San Diego. Whether that happens or not, I’m sure we will hear some cool news, and will still have some surprises when we see Avengers: Doomsday in theaters on December 18th.
