Avengers: Infinity War's villain Thanos is such a threat that it's taking the combined forces of Earth's heroes and the Guardians of the Galaxy to even attempt to stop him.
But there is at least one Avenger who might have some appreciation for what Josh Brolin's big bad is up to.
Mark Ruffalo has revealed that The Hulk may have some sympathy for his fellow, brightly coloured giant.
"The Hulk is also mightily impressed by Thanos," he told Coming Soon.
He added that the human version of his character, Bruce Banner, struggles to reintegrate with his old allies after returning to Earth.
"Once again, I think he's trying to find his place in the line-up. He's having some difficulties integrating with the rest of the group, but he's also privy to some information that is essential for their survival.
"Banner knows more about Thanos than probably anybody and he's really trying to impress on everybody how dangerous he is."
Thor: Ragnarok finished with Banner – along with Thor, Loki and the Asgardian refugees – being captured by Thanos's spaceship. What will he learn by coming face to face with the villain?
The experiences he went through in that film might also have affected his friendship with Tony Stark.
How might Hulk's sympathies for Thanos affect his actions in Infinity War? He might have grown in intelligence between Avengers: Age of Ultron and Ragnarok, but he is still essentially the most powerful being on Earth controlled by a mind like a child's.
Avengers: Infinity War will be released on April 26 in the UK and on April 27 in the US.
