Hulk's Ultimate Form Is So Powerful That He Makes Galactus Look Pathetic

The Hulk has always been one of Marvel's strongest characters, but his most terrifying form takes that power to a completely different level, making even a cosmic powerhouse like Galactus look downright pathetic by comparison. Bruce Banner has gone through plenty of wild transformations since The Incredible Hulk #1 debuted in 1962, from World War Hulk to the Immortal Hulk and everything in between. Yet none of them come close to the sheer insanity of the One Below All Hulk, the horrifying version of the Green Goliath introduced in Al Ewing and Joe Bennett's acclaimed Immortal Hulk run.

Immortal Hulk completely changed the way gamma radiation works in Marvel, revealing that it can act as a gateway to the mysterious One Below All. Eventually, in a far-future version of the Marvel Universe, the entity takes control of Bruce Banner and turns the Hulk into something far worse than another angry monster. As the "Breaker of Worlds," Hulk becomes a cosmic nightmare capable of killing Galactus, crushing stars with his bare hands, and wiping out an entire reality until nothing remains but himself.

At that point, comparing Hulk to Galactus almost feels unfair. Galactus has spent decades being one of Marvel's ultimate cosmic threats, but the One Below All Hulk reaches a level where even the Devourer of Worlds can look completely helpless.

The One Below All Turns Hulk Into Marvel's Ultimate Demonic Nightmare

The story behind Hulk's ultimate form gets seriously crazy in Al Ewing and Joe Bennett's Immortal Hulk. The series takes Bruce Banner's already bizarre origin and basically asks, “What if gamma radiation was connected to something much, much worse?” Instead of being nothing more than the result of a freak lab accident, gamma energy is revealed to be tied to the Green Door, a mysterious gateway leading straight to the Below-Place.

The Below-Place is essentially the lowest and darkest layer of Hell, where the malevolent cosmic entity known as the One Below All resides. And this is where things get seriously creepy for Hulk and every other gamma mutate. Whenever a gamma mutate dies, their soul passes through the Green Door and ends up in the Below-Place before eventually returning to the world of the living. That resurrection cycle gives the One Below All a chance to influence its victims, making death itself part of the entity's connection to gamma-powered beings.

But the One Below All isn't simply some evil god waiting for a chance to fight Hulk. It is pure destruction given cosmic form, with no real body or personality of its own, much more like a demonic symbiote. To actually act in the physical universe, it needs a host. And eventually, it finds the perfect one in Bruce Banner.

Far in the future, the One Below All completely takes over Hulk, transforming him into the Breaker of Worlds. This is where the story goes completely off the rails. Hulk is no longer just the strongest monster in the room; he becomes a cosmic force capable of going toe-to-toe with beings like Galactus and eventually destroying him outright. The Green Goliath has officially gone from smashing superheroes to threatening the entire fabric of reality.

This Ultimate Hulk Form Easily Kills Galactus And Ends The Eighth Cosmos

Things get completely insane when Immortal Hulk jumps all the way to the end of the Eighth Cosmos. And there isn't much in Marvel's cosmic hierarchy that can stop him. The Breaker of Worlds tears through some of the most powerful beings in existence, killing Franklin Richards, Mr. Immortal, and even Galactus.

The same Devourer of Worlds who has spent decades being one of Marvel's biggest cosmic threats is completely outmatched by a Hulk possessed by the One Below All. The Breaker of Worlds even devours the Sentience of the Cosmos before continuing his rampage across the newly formed Ninth Cosmos.

Eventually, there is nothing left to fight. No heroes, no civilizations, no cosmic gods, and seemingly no one left to stop him. The entire reality is wiped out until the Breaker of Worlds is the only thing remaining.

That is what makes this version of Hulk so terrifying. He isn't simply stronger than the usual Hulk. The One Below All turns his endless rage and impossible durability into the power of a cosmic destroyer. Galactus may be the Devourer of Worlds, but the Breaker of Worlds is what happens when Hulk becomes powerful enough to destroy everything that remains.
