The Hulk is one of the most popular superheroes in the world, and hes been around for a long time.

As a result of this longevity, the Marvel Cinematic Universes Hulk has gone through many transformations throughout his years on screen. For example, Bruce Banner used to be played by Edward Norton, and now hes played by Mark Ruffalo. The Hulks changes have been more than skin deep, too, as Banner has been slowly learning about how to control the Hulk.

That said, in the comics, the Hulk changes even more, and some Marvel fans are convinced that in the movies, hell become similar to his comic book counterpart.

The Hulk has always been a classic case of Jekyll and Hyde, where Banner is just a regular guy but hell turn into the Hulk whenever hes angry. In the beginning of Banners story, hes just trying to figure out why this is happening to him.

However, by the time that he shows up in the first Avengers movie, Banner revealed to the team that he can transform into the Hulk whenever he wants, since hes always angry.

Banner continues to gain more control of the Hulk as the Marvel movies progress. InAge of Ultron, Scarlett Johanssons Black Widow says a lullaby that calms him down and allows him to transform back into his human form.

In the most recent Marvel movies, Banner has complete control of the Hulk, and hes able to be a regular person while in his Hulk form.

As a result, some Marvel fans on Reddit think that the Hulk has done transforming in the movies. By becoming Professor Hulk, as hes called, Banner has been able to completely control that side of him.

This would seem to be the natural end to the Hulks story, since controlling the Hulk was always the thing that Banner has strived for.

Like one fan said, Professor Hulk is the endpoint of Ruffalo. Other fans agreed, and one fan said, I think theyll drop the character for awhile.

Some fans speculate that Marvel is introducing She-Hulk on her Disney+ show as a way of passing the torch between the Hulk and She-Hulk.

That said, some fans disagree with this idea.Endgame was the endgame for many Marvel characters. Iron Man and Black Widow both died inEndgame, and Captain America retired and passed his shield off to the Falcon. Fans think that if Marvel was done with the Hulk, Marvel wouldve ended his story atEndgametoo, but Marvel didnt.

In the comics, the Hulk is able to absorb radiation to become stronger. This has led to some interesting stories, and they could potentially be where the Marvel movies will take the character.

For example, many fans on Reddit think that the Hulk will eventually transform into Worldbreaker Hulk. Worldbreaker Hulk is one of the most powerful characters in Marvel history, and, like his name implies, hes so strong that he can destroy entire planets.

The Marvel movies has somewhat hinted at adapting this storyline, but Marvel came short of actually adapting Worldbreaker Hulk.

And then theres Maestro, which is another possible direction that Marvel can take the Hulk. In the comics, the Hulk absorbs so much radiation that he becomes Maestro. Hes still as strong and as tough as the Hulk is, but Maestro gained new powers after his transformation, and they include a few psychic abilities.

These were the two most popular theories, but there are more options. Either way, many Marvel fans are still hopeful that Ruffalos Hulk will show up again in the MCU.
