Just what kind of role Spider-Man will have in Infinity War remains to be seen.
In the Infinity Gauntlet series, which forms the basis for the Infinity War movie, Spider-Man is one of the last heroes called up to battle Thanos and he gets bashed over the head with a rock.
Spidey is set to star in Spider-Man: Homecoming ahead of his shot in Infinity War, so perhaps developments in the first film will give some hints about how Spider-Man fits into the Avengers picture.
Considering what a giant part Infinity War figures to play in the overall MCU, you have to believe the movie will be “epic” in every way.
