10 MCU Loose Ends That Drive Fans Crazy
5. How Exactly Did Banner And Hulk Reconcile Their Issues?
Marvel Studios trolled everyone with its Avengers: Infinity War marketing, leading people to believe that Hulk would be unleashed during the final battle in Wakanda.
In reality, Bruce Banner and his angry green friend had relationship issues for the entire movie, with Hulk refusing to do any of the punching, forcing Banner to don the Hulkbuster armour in order to stand a fighting chance.
But the very next time we see Banner in Avengers: Endgame, he and the Hulk have somehow fixed their problems and merged personalities, becoming Smart Hulk. The movie never properly explains how this came to be, with that explanation actually being cut from Avengers: Infinity War. The filmmakers felt that audiences would just "go with it" when Smart Hulk randomly appears in Endgame, so that's how they did it.
The Banner/Hulk reconciliation again went unexplained in Shang-Chi and the Legend of the Ten Rings, where Banner was back to his regular human self. Then, in the She-Hulk footage we saw a few months ago, he was back to Smart Hulk. What gives?
It's possible that She-Hulk will provide more of an insight into Banner and Hulk's newfound ability to merge and de-merge at will, which has gone completely ignored for the last several years. The character works without us knowing, sure, but such a pivotal moment in Banner's development does deserve some level of exploration.
