Josh Brolin is already set to return as the titular villain, last time we saw him he had completed his random, non-biased genocide and is now peacefully sitting on a farm somewhere basking in his work.
Making there ‘Avengers’ debut will be Ant-Man & the Wasp, while Scott Lang was present for Captian America: Civil War, it resulted in him being placed under house arrest (as mentioned in by Black Widow). He’ll be joined by the Wasp in their upcoming film in August, which is believed to be a segue to next year’s Avengers film.
Also making their big crossover debut is Captain Marvel, while she was initially meant to turn up in Infinity War the Russo brothers felt it was much more appropriate to debut her in her solo film first, which will be released in UK cinemas on March 8 2019. However, she was teased in Infinity Wars post-credit scene when Nicky Fury sent her a distress page before fading out of existence.
One character who was suspiciously missing from the biggest Marvel movie so far was Hawkeye, he hasn’t been seen since the events of Civil War which has him under house arrest too. However knowing Clint Barton, he won’t be sitting out the fight for too long, expect to see him back in action next year. Possibly as Ronin.
Also returning are those who survived Thanos’ mass genocide including Captain America, Iron Man, War Machine, Rocket, Black Widow (who is getting her own solo movie soon), Nebula, Thor and Bruce Banner (and possibly The Hulk – providing he’s gotten over his stage fright).
What’s interesting is the character’s who died particularly as most of them are getting solo sequels, the most surprising to bit the proverbial dust was Spider-Man and Black Panther. Both characters already have confirmed sequels in the works.
One character who won’t be making their debut is Adam Warlock, who will presumably make his debut in Guardians of the Galaxy Vol. 3.
