Mark 48

The Mark 48 (Mark XLVIII), also known as "Hulkbuster Mark II", is an extra heavy modular armor, created by Tony Stark and Bruce Banner as a security guarantee in the event of an uncontrollable Hulk uproar or other possibilities.

The armor was featured in Avengers: Infinity War, and it was used to fight against The Outriders and Thanos' Black Order.

Its design was based entirely on the previous Hulkbuster, only with updated and more streamlined armor plates. The Mark 48 is extremely large in size. The armor has a dark red hue as its general coating color, along with the gold and silver plates in various areas of its structure. It is covered with layered dense gold-titanium pieces and has several arc reactors around its body.

The Mark 48 is also 11 feet high, like the previous Hulkbuster, and 3 feet higher than the Hulk. Apart from its height, it is also the second heaviest armor that exists in the MCU.

The Hulkbuster Mark II is a Modular Armor Bruce Banner used it in the Battle of Wakanda.

Trivia
- In promotional trailers for Infinity War, Hulk was digitally shown in place of Bruce wearing this armor (perhaps to hide certain plot points).
