He’s naked in a hot tub. That’s basically the first thing we see of the Hulk in Thor Ragnarok after he’s done smashing a giant wolf. It was a massive departure from the "always angry" engine of destruction we saw in the earlier Avengers films, and honestly, it’s exactly what the Marvel Cinematic Universe needed at the time.
Before Taika Waititi got his hands on the franchise, the Green Goliath was mostly a plot device. He was the ticking time bomb the team had to manage or the heavy hitter they brought out for the third-act climax. But on Sakaar? He was a person. A weird, petty, toddler-brained person who liked giant beds and cheering crowds.
The Sakaar Shift: More Than Just a New Haircut
When Thor finds him on Sakaar, the Hulk hasn't turned back into Bruce Banner for two years. Two whole years. That is a massive detail that a lot of casual fans breeze past, but it’s the entire reason the character works so well in this movie. Because he’s been "out" for so long, he’s actually started to develop a personality that isn't just pure rage.
He talks. He sulks. He watches holographic recordings of himself.
Mark Ruffalo’s performance here—provided through some of the best motion-capture work of 2017—gives the Hulk a range of emotion we hadn't seen. He’s basically a celebrity athlete who has never been told "no." When Thor tries to convince him to leave, Hulk’s reaction isn't to roar; it’s to get defensive because he finally feels loved. On Earth, people screamed and ran. On Sakaar, they wear green masks and chant his name. You can't really blame the guy for wanting to stay.
Why This Version of Hulk Actually Matters for the MCU Timeline
The Hulk in Thor Ragnarok serves as the bridge between the mindless beast of Age of Ultron and the "Smart Hulk" we eventually see in Endgame. Without this middle step, the jump to Bruce Banner in a cardigan would have felt completely unearned.

In Ragnarok, we see the "Hulk" side of the brain taking the steering wheel. He’s learning language. He’s using basic logic. He calls Thor "baby arms." It’s hilarious, sure, but it’s also vital character development. We’re seeing the two personas—Banner and Hulk—start to bleed into each other. Banner is terrified of losing control forever, while Hulk is terrified of being suppressed and hated again.
The Power Scale Problem
Let’s talk about the fight with Fenris. Or the "rematch" with Thor in the Grandmaster’s arena.
People argue about power levels constantly. Is Hulk weaker in this movie? Some fans think so because Thor almost beats him before the Grandmaster cheats. But honestly, it’s not about strength; it’s about the stakes. In Ragnarok, the Hulk in Thor Ragnarok is fighting peers. He’s not smashing nameless Chitauri aliens anymore. He’s going up against the God of Thunder and an undead giant wolf the size of a city block.
The choreography in the arena scene is particularly brilliant because it treats Hulk like a brawler. He uses the environment. He catches hammers. He gets frustrated when his opponent doesn't stay down. It’s the most "human" a fight involving a CGI monster has ever felt.
The Tragedy Behind the Comedy
Waititi is known for his humor, and Ragnarok is undeniably one of the funniest movies in the MCU. But there is a real darkness under the surface of Hulk’s story here.

When Banner finally emerges after seeing the recording of Black Widow, he is devastated. He realized he’s lost years of his life. He’s on a different planet. His friends are gone. He’s convinced that if he turns into the Hulk one more time, Bruce Banner might never come back. That is high-stakes drama tucked inside a movie with neon colors and 80s synth music.
This internal conflict is why the final leap onto the Bifrost bridge is so heroic. Banner knows the risks. He thinks he’s sacrificing his humanity forever to save people who used to be afraid of him. It’s a complete 180 from his character arc in The Avengers, where he was just trying to stay out of the way.
What Most People Get Wrong About the "Nerf"
You’ll see a lot of YouTube essays claiming Marvel "nerfed" the Hulk starting with this film. They point to him losing the opening fight in Infinity War against Thanos as the beginning of the end.
But look at the Hulk in Thor Ragnarok again. He isn't weaker; he’s just more complex. The "Worldbreaker" version of Hulk from the comics is cool, but it doesn't leave much room for dialogue or emotional beats. By giving him a voice—even a simplistic one—Marvel allowed the audience to care about what the Hulk wanted, not just what Banner wanted.
Breaking Down the Combat Evolution
If you watch the fight scenes closely, you’ll notice Hulk’s style has changed.

- He uses weapons (those massive Sakaarian axes).
- He displays tactical awareness, like when he uses the momentum of Thor’s own hits against him.
- He shows genuine joy in the struggle.
The "Surtur, move!" moment is a perfect example. He sees a giant fire demon and his first instinct isn't "I must save the world," it’s "I want to fight that big thing." It’s pure, unadulterated Hulk.
Key Lessons for Fans and Writers
The success of the Hulk in Thor Ragnarok proves that you can take a "flat" character and give them depth without stripping away what made them popular in the first place. You don't have to choose between "Smash" and "Story." You can have both.
If you’re looking to revisit this era of the MCU, pay attention to the specific ways the lighting and color palette of Sakaar reflect Hulk’s mood. The vibrant, chaotic greens and purples match his newfound freedom. It’s a far cry from the muted, industrial grays of the Avengers' facilities.
Actionable Insights for MCU Completionists:
- Watch the "Team Thor" shorts: They provide a bit more context on why Banner was feeling so isolated before the events of the film.
- Compare the "Lullaby" scenes: Contrast the way Natasha calms him in Age of Ultron with the way Thor tries (and fails) to use the same technique in the Sakaar arena. It highlights how much Hulk has outgrown that specific psychic leash.
- Track the Banner/Hulk ratio: Notice how, by the end of the film, Banner is starting to use Hulk-like phrasing even when he’s in human form. It’s the first real hint of the integration that happens off-screen before Endgame.
The Hulk we see on Sakaar is the most realized version of the character because he’s allowed to be a character, not just an effect. He’s funny, he’s scary, and for a brief moment, he was the undisputed king of the arena.
