Avengers: Infinity War - Predicting The Entire Plot In 20 Steps

3. Banner Loses Control Again

Bruce Banner's arc from the moment he crash-lands back on Earth will follow the anxieties he explicitly explored in Thor: Ragnarok - the fear that he will lose control completely the next time he allows himself to Hulk out.

And because he's basically useless in a battle environment as Banner (aside from in terms of strategy, perhaps), he comes equipped with a new, improved Hulkbuster armour courtesy of Tony Stark that allows him to compete with the invading army. Unfortunately, it looks like he's easily over-run by the sheer number of Outriders that attack him, leading to him losing control and transforming into the Hulk against his will.

Despite how unhappy you'd think he'd be about having been forced off Sakaar, where he was a beloved hero and dropped into the middle of a war that isn't his own, Hulk will then align with the Avengers again, presumably proving Banner's argument wrong. Expect Black Widow to play a key role in that happening.
