The multiverse crossover setup for Avengers: Doomsday, arriving in theaters December 18, drives trader focus on character inclusion, with Marvel confirming a large ensemble spanning Avengers veterans like Steve Rogers and Thor, the Fantastic Four led by Reed Richards, and Fox-era X-Men including Charles Xavier and Magneto. Directors the Russo brothers have teased additional unannounced appearances, notably hinting at Hulk involvement in the Doom-centered story while leaving room for surprises beyond the roughly 30 publicly listed roles. Recent promotional activity, including SDCC panels, D23 footage, and strong pre-sales exceeding $50 million domestically, reinforces momentum around core teams uniting against Robert Downey Jr.’s Doctor Doom, though conflicting reports persist on figures like Spider-Man and Doctor Strange.
