DirectorJoss Whedonhas been making the press rounds of late to promote his highly-anticipatedMarvel Phase TwoadventureAvengers: Age of Ultron, arriving in theaters May 1. While this movie appears to be his lastMarvelmovie in the foreseeable future, theAvengerswill return withAvengers: Infinity War Part 1in 2018 andAvengers: Infinity War Part 2in 2019, which will be directed byAnthony RussoandJoe Russo. During a recent interview with Vulture,Joss Whedonrevealed that Thanos (Josh Brolin) won’t be the only villain in the two-part Infinity War movie.

“A lot of people were surprised that Thanos wasn’t the villains in Avengers 2, but he was never meant to be. He was always meant to be the puppet-master until he was done doing that, and then he’ll be the big villain they face off with. Not solely - I’m sure there’ll be plenty more [villains] in that monstrous epic, because one thing Marvel doesn’t do is string a story out into two movies that shouldn’t be two movies. They’ll give you two big movies. I feel like we got two movies into this one!”

Of course, this leads to the question of what other villains may be popping up in Infinity War alongside Thanos. ProducerKevin Feigealso revealed over the weekend that while Infinity War may technically be a two-part movie, they are both two separate and fully-functioning movies in their own right. It’s possible that the movie could bring in both of Thanos' daughters, Gamora (Zoe Saldana) and Nebula (Karen Gillan) from last year’sGuardians of the Galaxy. Fans may also be introduced to a group of villains who fight with Thanos known as the Black Order, which includes Corvus Glaive, Black Dwarf, Ebony Maw, Proxima Midnight, and Supergiant. Since this is a massive two-movie event, Marvel could theoretically bring in all of the previous Phase One and Phase Two villains who are still alive, as they side with Thanos against Earth’s Mightiest Heroes.

Naturally, this is all speculation, but there is certainly plenty of villains that could side with Thanos inAvengers: Infinity War Part 1andAvengers: Infinity War Part 2. Who would you like to see pop up and fight with Thanos? Let us know what you think below.
