Abomination – Emil Blonsky. A gamma-spawned monstrous powerhouse. The Hulk's primary physical rival.
The Leader (Samuel Sterns) is a supervillain appearing in American comic books published by Marvel Comics. The Leader first appeared in Tales to Astonish #62, created by writer Stan Lee and artist Steve Ditko as the archenemy of the Hulk.
Cyclops' brother, Havok, is one of the few Marvel superheroes who can defeat the Hulk in a fair fight. Alex Summers aka Havok may not be as popular as his more famous brother, but he is easily one of the most powerful mutants in the Marvel Universe.
The Avengers found that a certain lullaby, typically said by the Black Widow, was able to calm the Hulk and help him revert back to Banner, when the Hulk's strength was no longer needed.
Loki – Thor's archenemy and adoptive brother. The son of Laufey, ruler of the Frost Giants of Jotunheim, one of the "Nine Worlds" of the Asgardian cosmology. He is a master of spellcasting and trickery.
Weakness: ADAMANTIUM AND VIBRANIUM
Swords, knives, and more have been used against Hulk and almost none of them even leave a scratch or mark on him. However, with that said, there are two bladed weapons that can cut into Hulk's skin. Adamantium is something that can cause damage to Hulk.
Losing Himself
Not to go too far down the rabbit hole of pop psychology, but what Hulk and Banner are most afraid of is losing themselves to one another.
The Hulk has been called the strongest Avenger given his unparalleled, planet-shattering strength, but within the 2099 future of Marvel and DC's crossover universe, the Hulk would be considered the weakest Avenger (for one specific reason).
He can lift a commercial airplane – which weighs around 100 tons – when he is at his calmest; that's no problem for him. But the angrier he gets the stronger he gets, and if the Hulk is really pissed, then he can lift anything, including mountains, or even planets!
Apocalypse makes his way into this position on the list because he is technically stronger than the Hulk. He also has a multitude of other abilities, including telepathy, telekinesis, and shapeshifting. And that's just touching the surface of his powers.
So, there you have it. Thanos beats Hulk every time, with or without the Infinity Gauntlet. But World Breaker Hulk defeats Thanos. However, Thanos could beat the Hulk if he had the Gauntlet (He could wipe out the Universe).
Before he can defeat him, the Immortal Hulk is stopped by the Savage Hulk, who is being emotionally manipulated by the Leader. The Immortal Hulk is beheaded by a monstrous Leader and his heart is ripped out. His corpse, alongside Banner, is taken to the Below-Place by the Leader.
Thor doesn't always save the day in Marvel Comics, and some of his biggest losses include falling to Thanos and Gorr the God Butcher. Thor: Love And Thunder revisits Thor after he has lost everything, including his home in Asgard, his brother Loki, and his sense of place in the universe.
Doctor Doom
Not everyone who has lifted Thor's hammer was worthy to hold Mjolnir. A perfect example of this is Doctor Doom, one of the world's most dangerous villains. While Doctor Doom is a master of magic and science, it was his luck in finding the hammer that allowed him to wield it.
Mandarin - The archenemy of Iron Man, the Mandarin is a Chinese nobleman, scientist and former diplomat turned criminal mastermind.
Of course, even despite his Asgardian strength, Loki is no match for the Hulk so he doesn't bother using his strength to subdue the beast. He manages to use something else. Loki realizes he can't beat or trick the Hulk so he does something a little different: he rips the gamma radiation out from Hulk.
All-in-all, while Iron Man is a formidable opponent for the Hulk and has a few wins under his belt, the Hulk has undeniably won more comic battles against Iron Man than Iron Man has against the Hulk, proving once and for all that the Hulk is the superior fighter between the two of them in Marvel Comics.
The final verdict. It would be a very long fight since the Hulk is incredibly hard to kill, thanks to his super-tough skin. But, in the end, Doomsday would be the winner due to his never-ending strength and endurance.
Whether it was magic-wielding sorcerers like Doctor Strange or entire teams like The Avengers, almost nothing can get in Hulk's way when he's on a rampage. Though he has beaten the best of the best, only his biggest victories left readers stunned at the sheer power of Bruce Banner's alter ego.
No world was safe from this Hulk's power or rage, and it was a living embodiment of entropy. Without an Infinity Gauntlet, destroying planets with one punch was far beyond what any other Hulk or being in the Marvel Universe could muster. This made the Entropy Hulk the strongest Hulk of all.
World Breaker Hulk is stronger, more durable, faster, and has limitless stamina at his disposal, being able to fight seemingly forever.
In Infinity #6, the Hulk supports the entire weight of a star with his strength alone. If the star's weight was equivalent to the weight of Sol, the Hulk is capable of lifting 2 octillion tons.
His strength increased as more and more energy from an alternate universe was channeled into him, giving the Hulk greater power that could destroy the universe. Can channel enough energy to destroy two universes.
