Previously unseen concept art from Avengers: Endgame has recently been revealed, and I’m sad that the epic MCU crossover event cut one brilliant moment that would have seen Bruce Banner’s Hulk team up with the Black Panther. Avengers: Endgame, one of my personal favorite MCU movies, marked the culmination of over a decade of live-action superhero adventures, and included some huge transformations for many veteran heroes. Few saw as many alterations as Mark Ruffalo’s Bruce Banner, however, who revealed his Smart Hulk persona in Endgame.
