I remember people were arguing that Hulk was the same size as he has always been. I don’t believe this is the case. I remember him being noticeably smaller than usual.
In this first picture you can see his height at the end of Ragnarok. He is much taller and larger than Korg.
In Endgame, in a shot of them together, he is definitely smaller.
I know this has been argued a lot, but makes me wonder if he was officially nerfed in Endgame.
