Of all the Marvel characters confirmed to appear inSpider-Man: Brand New Day, one of the most mysterious is The Hulk. Mark Ruffalo is confirmed to reprise his role as Dr. Bruce Banner in the upcoming Spider-Man film, though his Hulk persona has been absent from the marketing (however, a LEGO set has confirmed his appearance). Despite Bruce Banner having mastered control of the Hulk in Avengers: Endgame, it is widely known that at some point in Spider-Man: Brand New Day, Banner will lose control and force Spider-Man to face off against the Hulk. Though the cast might have teased a different look for the Hulk.
