Captain America is physically stronger than Iron Man, whether with his suit or not. If they both entered a ring-to-box hand-to-hand combat, Captain America would destroy Iron Man in that fight. However, if we consider all features in their respective arsenals, Iron Man would literally toast Cap.
Who would win in a fight Captain America or Iron Man?
Captain America stomps. The only way Tony has a chance is if he has some prep time. Maybe he can rig something up. Cap is VERY vulnerable without his shield so when you say without the iron man armour, like, can Tony have his wrist watch repulsor?
Though Tony Stark ultimately lost his fight against Steve Rogers, it wasn't because he was weaker. Instead, he knew the only way to beat him would be to kill him, and Steve wasn't going down without a fight.
While nearly a decade has elapsed since Captain America and Iron Man went toe-to-toe during the events of Civil War, the fallout of their battle still had effects on the franchise.
Marvel's Iron Man is officially stronger than Captain Marvel, confirms the publisher in Iron Man #22. The Armored Avenger is known for his many powerful suits of amor and not necessarily his own fighting skills; without his suit, he is easily defeated.
Thor beat Iron Man easily. Iron Man was basically powerless against the God of Thunder. Thor stopped short of beating Iron Man to death, but he made sure that Iron Man knew that there was nothing he could do to Thor if Thor pressed the issue.
It ended with the Hulk's eventual triumph as he stood victorious over Iron Man's fractured armor. Despite the previous defeats from the Hulk, Iron Man could still subdue him in some instances, like in Iron Man #132. Tony aids Banner, allowing him facility access to separate from the Hulk.
Any MCU suit , even mark 85 would lose to Thor easily. But the comics pose a different story, while Thor would win most of the time Tony has two suits that could take him out. Thor Buster. This suit mimics the destroyer and possesses asgardian magic, it was made to take out Thor, so it probably will.
To Iron Man, Captain America committed the ultimate betrayal of his own morals, and to do this directly at him -- someone Rogers spent an entire movie calling out for the same motivation --would be the ultimate breaking point.
Iron Man Beat Hulk by Stabbing Him Through the Eye
Of course, it's not without a price - the damage Tony takes during the fight leaves his suit dangerously overloaded, and it explodes just moments later (though thankfully long enough for Tony to send it flying away, and escape the danger zone.)
Captain America confronts him one on one but Thanos is too powerful. Thanos dispatches Captain America with a simple and humiliating backhand. Cap wasn't alone, though; many Avengers who should beat Thanos, didn't.
While Captain America is hardly considered one of Marvel's most powerful heroes, he has performed many feats that go above and beyond the scope of his superpowers, including his defeat of a rampaging Hulk using only his fists (and a little help from Spider-Man).
Steve Rogers is one of the few mortals able to not only lift Mjolnir, but wield its full power, making him someone who legitimately could defeat Thor. Assuming the reason for their battle is due to Thor being deceived, possessed, or otherwise out of his mind, Cap would be able to use Mjolnir against him.
Aside from enhanced strength and speed, Cap also gained enhanced reflexes — enough to dodge bullets from point-blank range. While Batman, though more reflexive than an average human, just wouldn't cut it in the reflexes department. In a Batman vs Captain America reflex-combat, America would take the win.
Although he is an extremely skilled marksman, Clint Barton is often considered to be the weakest member of the team seeing as he's just a regular guy with a bow and arrow. That certainly means that Hawkeye one of the weakest Avengers.
Quicksilver is, quite literally, unbelievably fast. Others around him assume he's doing nothing even when he suggests slowing down camera footage so they can see what he's been doing. It provides some fantastic humor to incredibly serious superhero stories.
Summary. Thanos' death in Avengers: Endgame by Iron Man wielding the Infinity Stones is the most iconic and satisfying death in the MCU. Thanos' beheading by Thor in Avengers: Endgame is a darkly satisfying moment of character development and raises intrigue for the plot.
Strength. Captain America is physically stronger than Iron Man, whether with his suit or not. If they both entered a ring-to-box hand-to-hand combat, Captain America would destroy Iron Man in that fight. However, if we consider all features in their respective arsenals, Iron Man would literally toast Cap.
In general Superman would win round one easily. He could literally cut the armor off Tony without scratching him. On the other hand given time to prepare Tony Stark would give Superman a good run for his money in round two before eventually being defeated there too. Superman is a few grade levels above Iron Man.
Even at his most powerful World Breaker Hulk version Odin absolutely destroys. Hulk is ridiculously durable and can regenerate most physical damage but is still mortal, he can die.
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.
While Thanos is usually the victor, it's generally down to him using superior tactics and technology, rather than simply possessing greater physical strength. However, when the two clashed in Infinity War, Thanos beat Hulk in a wildly one-sided fight.
