Warning: Possible Avengers: Age of Ultron spoilers ahead!

Iron Man, Captain America, Thor, Hulk, Black Widow and Hawkeye comprised the original cinematic lineup of Marvel's Avengers, and a trio of new additions in the way in Age of Ultron: Quicksilver, Scarlet Witch and Vision.

But that's not all, according to a new rumor from Badass Digest's Devin Faraci, who contends that, by the end of the Joss Whedon sequel, even more heroes will enter the fray:

"At the end of Age of Ultron Cap will assemble a team that is a mix of familiar and new faces, leading forward into Phase Three. It's an exciting mission statement for Marvel Studios, letting audiences know that the Avengers team is more than just the guys who were in the first film. The make-up of that team is, technically, up in the air until that scene is shot (I suspect it's being saved for either scheduled reshoots or will be snuck into the schedule of Captain America 3, which goes before cameras early next year), but Joss Whedon's script did indicate who would be on that team."

Faraci says that Captain Marvel, originally intended to be a part of this end-of-the-movie cameo sequence, might get cut. According to the report, the studio has plans to include Carol Danvers in the Marvel Cinematic Universe -- and soon -- but "they're not certain they want to introduce her in this way. They basically aren't certain they want to just drop her into the MCU fully formed in a team movie."

Take what you will out of the report. We'll see the full squad in all of its mighty glory when Avengers: Age of Ultron assembles on May 1, 2015.
