As Seen in Spider-Island #4 by Christos N. Gage and Paco Diaz
In a world where everyone in Manhattan has been transformed into spider-creatures by the monstrous Spider-Queen, the only escape is to block her influence with an even more extreme mutation. In response, the Avengers voluntarily underwent monstrous transformations, with Captain Marvel using Morbius' vampire serum, Captain America becoming a werewolf, and the Hulk downing the concoction that created Spider-Man's old enemy the Lizard. The result was the towering Lizard-Hulk.
As the Lizard-Hulk, Hulk was marginally stronger and gained armored scales all over his body, as well as vicious claws and teeth. However, his most impressive upgrade was a gigantic tail, giving the Hulk yet another superstrength limb to use in combat.

As Seen in Fear Itself #2 by Matt Fraction and Stuart Immonen
When the dark god known as the Serpent invaded Earth in Fear Itself, he brought with him eight hammers containing the bound souls of ancient Asgardian demons. These hammers were attracted to heroes and villains 'worthy' of their power, with Hulk being possessed by Nul, the Breaker of Worlds. This resulted in a major strength upgrade for Hulk, resulting in Thor itting for the first time that he wasn't on the same power level as the Jade Giant. Hulk cut a swathe of destruction across the Earth until the Serpent was finally defeated by Thor.
As a separate entity, Nul is known as the 'black Hulk' and embodies entropy, causing anything it touches to crumble and break. Currently, the entity's hammer is held by Galehaut, a member of the Avengers' rival team the Twilight Court.

Such was the case in 1997, when Apocalypse transformed the Hulk into his latest Horseman of War. Hulk was the first ever mutant to be chosen to serve Apocalypse, but even the mutant supremacist villain couldn't deny Bruce Banner's limitless strength.
As War, the Hulk is given weapons including a gigantic sword and mechanical tentacles, as well as armor that influences his mind, turning him into a colder and deadlier warrior. As War, Hulk's strength was so extreme that he was able to stop the Juggernaut in his tracks. This is notable because the Juggernaut's magic momentum is meant to make him unstoppable no matter what is in his way, suggesting War Hulk is so strong, it overcame the power of Cyttorak - the demonic god from who Juggernaut derives his power.

The plan worked, and Bruce began his 'Smashtronaut' era, harnessing Hulk's power to turn himself into a one-person multiversal spacecraft. However, after a few adventures, Hulk began manifesting a new form known as Titan - an apocalyptic monster bursting with eldritch energy.
Titan was strong on a level usually reserved for gods, and could absorb energy from others, unleashing it in huge blasts capable of all-but-destroying entire planets. Ultimately, Bruce discovered that the Titan was a creation of the demon D'Spayre, which had disguised itself as Doctor Strange in order to influence the Hulk.

Most of the zombies fall in the fight, but Hulk, Spider-Man, Wolverine, Luke Cage, Iron Man and Giant-Man 'survive,' eating Galactus' flesh and gaining a portion of the Power Cosmic.
Even one sixth of the Power Cosmic is more power than most gods possess, and Hulk was able to travel from world to world, eating all living beings to the edge of the universe in just forty years (with the other zombies noting Hulk ate the majority of their victims.) The Marvel Zombies went on to have many other adventures, but this upgrade turned Hulk into a natural disaster on a galactic scale.
