10 Powerful Hulks That are Too Much for the MCU

No Marvel powerhouse has worn more faces or raw power than the Hulk. Since bursting onto comic pages in 1962, Hulk has splintered into dozens of versions, each flexing a different brand of strength. Forget what you’ve seen onscreen; some Hulk forms in the comics make MCU Banner look quaint.

Here’s your guided tour through some of the strongest Hulk versions in Marvel history, how they differ, why they matter, and what sets the most dangerous gamma monsters apart from the rest.

The Original Hulk Wasn’t Green (Or All That Smart)

The Hulk you know, is emerald, but the first version was gray. Created by Stan Lee and Jack Kirby in The Incredible Hulk #1, the Gray Hulk had brute strength, yet lacked Banner’s brains entirely. Villains like Loki found it easy to manipulate this mindless version. The gray palette was meant to stick, but printing errors turned Hulk green, and that stuck. This split between Banner’s intellect and Hulk’s brawn has defined every reinvention since.

In issue two, Hulk officially became green, and the “Incredible Hulk” was born. More agile, more powerful, and able to leap continents, this version quickly cemented himself as a top-tier Marvel heavy. Early on, he fought Hercules to a draw, a feat on par with battling a god.

When Hulk Goes Off the Rails, and Off the Timeline

Some of Hulk’s wildest incarnations exist outside the main Marvel Universe. The Ultimate Hulk from Earth-1610 is one of, best known for ripping Wolverine in half. He’s tough, but not invincible; he lost to both Hercules and Thor, and was even manipulated by a powerful variant of Kang the Conqueror.

If the future gets darker, so does Hulk. Hulk 2099 is attorney John Eisenhart, mutated into a savage with steel-shredding claws and a prehensile tongue. He keeps his wits and his ability to change, which, ironically, puts him closer in spirit to She-Hulk than to Banner.

And then there’s the truly bizarre: Infernal Hulk of Earth-11638. After this universe’s Bruce Banner becomes the Sorcerer Supreme, he yanks Hulk out and banishes him to Hell. Hulk grows into a demon, obsessed with revenge. When Infernal Hulk finally breaks free, he rampages across Earth until he’s trapped, and ultimately killed, inside another Banner.

Combining Powers: Hulk Hybrids and Game-Changers

Not every Hulk is Bruce Banner. Sometimes, the genes (and the rage) get around. She-Hulk is Jennifer Walters, Banner’s cousin. Thanks to a fateful blood transfusion, she’s got super strength and keeps her intellect. She can even stay strong in human form. Hulk often edges her out in raw muscle, but She-Hulk has fewer limits, and her power continues to evolve both in comics and on Disney+.

The rules get rewritten with the emergence of Spider-Hulk: Spider-Man’s strength and reflexes, Hulk’s bulk. With Spider-Sense added in, this hybrid becomes nearly untouchable; danger seems to bounce off him in every universe where he appears.

Then there’s Weapon H, Marvel’s answer to the “what if we just broke the universe” question. Created to be the ultimate mutant killer, Weapon H is equal parts Hulk and Wolverine. He boasts Banner’s unstoppable might, Wolverine’s healing factor, and even adamantium claws. Weapon H can even shapeshift, swap between Hulk variants (Red Hulk, the Leader), and momentarily sprout wings or psychic powers. No other Hulk is this versatile or dangerous.

The Psychology of Pure Rage: Kluh, Green Scar, and Hulk’s Greatest Threats

Kluh is rage weaponised. This “reverse Hulk” is a deeply repressed persona inside Banner that erupts during Marvel’s AXIS event. Kluh wiped out one of the most powerful Avengers teams ever assembled, and showed new abilities like regeneration, telekinesis, and immunity to telepathic attack, plus the ability to see astral forms, a power usually reserved for mages.

Green Scar points to another flavour of Hulk’s psyche, the tactical, gladiatorial killer born in Planet Hulk. Exiled to Sakaar, he rises as a brutal champion before becoming ruler. The storyline inspired parts of Thor: Ragnarok, but the raw, cerebral violence of Green Scar’s era hasn’t come close to being touched in the MCU.

So, where do all these Hulks stand among each other? She-Hulk and Spider-Hulk dazzle with versatility. Weapon H and Kluh redefine what “unstoppable” means. Then you’ve got the Hulk truly unhinged, Infernal Hulk, Ultimate Hulk, and Green Scar top the scales as some of the scariest, least controllable forms of gamma-fueled anger. The strongest of all, though? That’s a question Marvel refuses to answer definitively, and maybe that’s the real point—no matter how strong Hulk gets, his rage always levels up.

• Gray Hulk (The Original): Brute, mindless strength, but easily manipulated.
• Ultimate Hulk: Showed extreme violence, but was outmatched by prime Marvel heavyweights.
• The Incredible Hulk (Green): Classic, agile, Hercules-level strong.
• Infernal Hulk: A demonised Hulk, pure rage, comes back from Hell for revenge.
• Hulk 2099: Future Hulk, claws, tongue, keeps full intelligence.
• She-Hulk: Banner’s cousin, power plus brains, underrated limits.
• Spider-Hulk: Spidey reflexes, Hulk muscle, plus Spider-Sense.
• Weapon H: Hulk and Wolverine in one, adds claws, healing, and more.
• Kluh: Hulk at his most dangerous; regenerates, can’t be mind-controlled.
• Green Scar: Arena-born gladiator, fought armies and became a king.

Until Marvel finds a way to put the truly unstoppable versions onscreen, the wildest Hulks will remain comic book threats, unconstrained, unpredictable, and somehow, always getting angrier.
