Set in
deep space, and in half a dozen lands (New York, Wakanda, Titan, Knowhere), the film presents a galactic battle for the fate of the universe that throws together the six original Avengers; the follow - up wave of Marvel superheroes who've only recently been given their own origin stories (
Black Panther, Dr. Strange, the rebooted Spider - Man); the Guardians of the Galaxy; and a sprinkling of other figures who've been there on the
fringes.
