**Recent Endgame Encore footage and Russo brothers' comments have sharpened trader focus on unannounced additions to Avengers: Doomsday's massive ensemble.** The late-September re-release added scenes confirming Bruce Banner/Hulk's involvement alongside Doctor Doom and introducing TVA agents Mobius, O.B., Casey, and Miss Minutes, lifting implied probabilities for those returns while directors teased further surprises beyond the 30-plus officially listed characters from the March 2025 livestream. Core confirmed players span MCU veterans like Steve Rogers, Thor, Loki, Shang-Chi, and the Thunderbolts crew; the new Fantastic Four; Wakandans; and Fox-era X-Men including Professor X, Magneto, and Gambit. High-odds speculation centers on multiverse cameos such as legacy Spider-Men and Wolverine, driven by historical crossover patterns and pre-release hype ahead of the December 18 theatrical bow. Markets remain sensitive to any final trailer drops or guild-adjacent buzz that could shift cameo resolution.
