The Hulkbuster armor is prominently featured in the latest Avengers: Endgame International promo art.
A new international poster (shared by ComingSoon) for Endgame shows the surviving heroes together, including the Hulkbuster armor. The armor originally debuted in Avengers: Age of Ultron as Tony’s way of fighting Hulk, but it returned in Infinity War for Bruce to wear thanks to Hulk’s issues. The new poster confirms it will return in Endgame in some form.
We have yet to see Hulk in the Avengers: Endgame trailers and TV spots, but he has been pictured in concept art, along with other merchandise. Earlier this week, he was spotted in a Funko Pop! 2-Pack with Thanos and he’s wearing the Quantum Realm suit, which started speculation about a possible rematch between the two.
There will surely be more international posters and TV spots that are released, but hopefully Marvel takes the same approach with all future materials as they have so far.
