When Avengers: Infinity War was released in 2018, a collective gasp reverberated in theaters around the world when Thanos plopped the final Infinity Stone into the Infinity Gauntlet, snapped his fingers, and the heroes, one after the other, dissolved into dust. With a scene as shocking as that, it is no wonder that a host of fan theories saw the light as soon as the credits started rolling.
Another mind-blowing scene in Infinity War shows Hulk battling Thanos and losing badly. Most fans couldn’t wrap their heads around this considering Hulk’s notable strength in Thor: Ragnarok. Even before that, Hulk had pummeled Loki as if he were nothing.
A popular fan theory proposes that Hulk was becoming weaker as Bruce Banner got stronger and started to take over Hulk’s body. By the time the events of Infinity War roll around, the Hulk is sufficiently weakened and unable to stand against Thanos.
In Avengers: Endgame, the Hulk we know is gone forever. In his place, we are introduced to Professor Hulk, who looks a lot like a huge, green Bruce Banner but is lacking brute strength.
