Next year's Avengers: Infinity War is set to be the Marvel Cinematic Universe's biggest movie yet, but Avengers 4 in 2019 after is expected to be equally as large in scope, if not more so. Serving as both the conclusion to Phase Three and wrapping up numerous storylines since the franchise's inception in 2008, nearly every major Marvel superhero is expected to appear in this spectacle. But it won't just be the heroes stopping by. For instance, last week, it was reported that Jurassic World actor Ty Simpkins will reprise Harley Keener, the boy Tony Stark befriended in Iron Man 3, for Avengers 4.
Taking Harley Keener's return into account, we've gathered together folks who haven't been seen in the MCU for a while and are deserving of a return by the time Avengers 4 rolls around. Starting off, let's look at a woman who's been MIA for nearly a decade and had a close connection to a certain green-skinned powerhouse.
Betty Ross was last seen in the MCU looking at a picture she took of Bruce Banner and wondering where he was following the battle with The Abomination. Her father, Thunderbolt Ross, recently resurfaced in Captain America: Civil War as the U.S.Secretary of State, but Betty hasn't been mentioned since The Incredible Hulk. Granted, Bruce has been busy in recent years aiding the Avengers and kicking ass on Sakaar, and given that Marvel is unable to make another solo Hulk movie, it's harder to squeeze supporting Hulk characters into these other movies. Nevertheless, it would be great if Bruce and Betty could reunite by Avengers 4, and if the rumors from earlier this year are true, it sounds like we will indeed see Liv Tyler reprising the scientist in the MCU soon.
Mickey Rourke's Ivan Vanko may have failed to be a compelling protagonist in Iron Man 2, but thankfully, Sam Rockwell's Justin Hammer was there to entertain moviegoers as a wannabe Tony Stark. Hammer was jailed for his crimes, and his cameo in the One-Shot short film All Hail the King implied he's acclimated to prison life relatively well. We don't expect Justin Hammer to become a notable antagonist again in the MCU, but that doesn't mean we can't check back in on him at Seagate Prison to soak in a minute or two of his self-centered personality. It'd been even better if he could engage in more witty repartee with Iron Man.
