Re: The Avengers 2! The Official News and Speculation Thread - Part 1
Very possibly. Joss even said the Adam Warlock revival story in Marvel Two-In-One Annual #2 and Avengers Annual #7 were some of his favorite stories.
That said, considering Jeff Sneider said he's heard that QS and SW would be in the film and it would make more sense for them to be two of his favorite character rather than "Her", I'm inclined to believe it's the Maximoffs.
