It was only after this transformation that Hulk could wield the Infinity Stones and reverse Thanos' snap, saving the universe. Smart Hulk became a huge MCU hero in the process, but it came at a cost. Using the power of the six Infinity Stones severely damaged his right arm, just as it did to Thanos.
From how this is stated it seemed the Russo brothers and Markus and Mcfeely intended for the damage from the stones to be permanent, but in Hulk's next appearance (which if I am not mistaken is Shang Chi), he's human and has a sling on his arm and then in She Hulk the injury seems to have completely healed.
As such, simply attempting to wield the Stones simultaneously would cause their collective energies to leak from the gauntlet and begin to severely wound the user if they did not have the physical capability to handle the stones' power, as was the case with Hulk or worse, fatal damage, as was the case with Iron Man.
Sedative Gas: The Hulkbuster armor contains Sedative gas in the wrist of its right arm to spray at the rampaging Hulk to (hypothetically) put him to sleep.
When Did Hulk's Arm Heal? Shang-Chi, She-Hulk & Endgame Timeline Explained!
What did Hulk's dad inject him with?
Blonsky was injected with a small dose of the mothballed original Super Soldier Serum and later was injected with Bruce Banner's blood causing him to transform into the Hulk-sized Abomination.
In Marvel Comics, Iron Man is debuting his strongest Hulkbuster yet to take the Hulk down once and for all. But even with its considerable bells and whistles, this titanic armor points to some character flaws deep within the Golden Avenger that continue to prove why Iron Man will never beat Hulk.
There's no question the Hulk is a near-indestructible force who comes out on top in almost all of his battles of pure strength. However, against Superman, he's outmatched. While Hulk's strength might rival that of the Man of Steel, Superman's other abilities give him a considerable edge against his opponent.
So while the MCU's Hulk may never go back to being angry the same way he was before, Bruce has a new set of personal demons to deal with that can have lasting repercussions on the MCU.
Given those characteristics, Thanos knows that a fight with the Hulk would be an incredibly dangerous undertaking that could end in his own demise. Because of the Hulk's incredible strength which seemingly has no limit, Thanos was afraid to fight him without the help of the Infinity Stones.
Thanos Beat Hulk Because He Was A More Skilled Fighter
Hulk's defeat could be because Thanos possessed the Power Stone, but with Thanos never pulling it out in the fight, the Russos believe that he didn't need it to win. Despite his great strength, pre-Avengers: Infinity War Hulk did not often fight with a strategy.
Thanos and Hulk have clashed several times in Marvel lore, with Thanos even admitting he was scared to face the Hulk before acquiring the Infinity Stones. While Thanos is usually the victor, it's generally down to him using superior tactics and technology, rather than simply possessing greater physical strength.
Did Hulk bring everyone back when he snapped his fingers?
Hulk's snap was different, and arguably more difficult. He was bringing everyone back and also trying to break the power of the Soul Stone. That's enough to tear up anyone.
The Hulk has one of the most powerful healing factors in the Marvel Universe, but his regenerative powers have an incredibly dangerous flaw. Most other characters with healing factors like Wolverine and Deadpool will always heal back in the same way, as their bodies rapidly repair damage.
While it has never been confirmed what Thanos' sword was made of, the Endgame battle hints that it was made of Uru or at least some metal that was as strong as the one from Nidavellir. Thanos was facing, at the same time, Mjolnir, Stormbreaker, Captain American's Vibranium Shield, and Stark's nanotech.
A Marvel fan seems to have figured out the real reason why Bruce Banner—played by Mark Ruffalo—could not transform into Hulk at will in last year's Avengers: Infinity War. Hulk was being too difficult to control for Bruce Banner in Avengers: Infinity War.
In fact, the only foe that fast who Hulk's ever seemed to keep pace with in a one-on-one match was Sentry, and that was when he was at his most powerful stage, Worldbreaker Hulk. Boomstick: So overall, Hulk had strength and Doomsday had speed, but neither completely outclassed the other.
The simple answer is no. Yes, Hulk absolutely smashes Thor to the ground with Mjolnir, but, he's holding both Thor and the hammer. Hulk wouldn't have been able to lift Mjolnir by himself, but since the God of Thunder had a firm grip on it as well, he was able to use it as a weapon against his teammate.
It's important to note that the rules around worthiness had been temporarily suspended to allow this to happen. As soon as the fight was over, Superman couldn't lift the hammer anymore. However, under normal circumstances, without any weird interference, Superman is worthy of Mjolnir.
Putting it all together, Thor can win against the Hulk, even if he can't kill the Jade Giant. Hulk is practically immortal and has unlimited reserves of strength and stamina, so he can keep fighting forever. Thor's endurance, while godly, is not limitless, so he will eventually lose a prolonged battle.
The Hulk reigns supreme over Iron Man in raw power. The embodiment of unfathomable power, his strength knows no bounds, growing exponentially as his anger intensifies. On the other hand, Tony Stark's suit grants him extreme strength and durability.
During the climactic New York City battle, there is no other Avenger who gives Hulk more of a hard time than Black Panther. Though he may lack the cosmic power of Thor or the raw strength of She-Hulk, T'Challa's ability to calculate events and read the moves of his opponents is unmatched, even for the Hulk.
The Hulk could smash the Scarlet Witch if given the chance. However, he magical abilities would easily prevent that from happening. Before Wanda became the Scarlet Witch, she had Thanos at her mercy. A character who dismantled the Hulk.
