Strength. Captain
Hulk has traditionally been seen as the strongest Avenger physically — and for good reason, though he's been subdued by both Iron Man and Thor.
He possesses vast superhuman strength enabling him to lift weights as heavy as a million tons without any effort. It is unknown whether Thor's strength has any limits at all. Also, he can shatter entire planets with the force of his blows. He has even broken through the armor of a Celestial in one blow.
Thor vs The Hulk who could lift more weight? In terms of LIFTING STRENGTH Thor and Hulk are practically the same. As long as there is an objective writer, they will essentially always equal each other LIFTING-WISE. Who do you think eats more, Thor or Hulk?
UNLIMITED STRENGTH
The answer; there isn't one. The amazing thing about the Hulk is that unlike nearly every other superhero ever created, the Hulk's strength has absolutely no upper limit. He can lift a commercial airplane – which weighs around 100 tons – when he is at his calmest; that's no problem for him.
For example, Marvel – which publishes the Thor comics – issued a “Thor's Hammer” trading card in 1991 that states Mjolnir is made of Uru and weighs precisely 42.3 pounds. That's lighter than a herd of 300 billion mice, much less a herd of 300 billion elephants. But it raises a different science question.
The Extremis armor increases Stark's strength to the point that he is able to lift up to 100 tons, the same as a calm Hulk. His most powerful armor is the Hulkbuster!
Colossus' incredible strength class is 100+, which means he can consistently lift above 100 tons. Colossus' most ridiculous feats in the comics further prove his elevated strength class. His power has been increased even further when he became Cyttorak's avatar and later a host for the Phoenix Force.
Superhuman Strength: Loki possesses superhuman strength that is substantially superior to that of an average Asgardian male. He can lift up to 50 tons.
However, at his peak during the time of the Celestials 3rd host on Earth, Odin could lift 75 tons, but in Odin's physical prime, he could lift 90 tons. He's also able to augment his strength to even greater heights by tapping into the Odin Force.
Superhuman Strength: Deadpool is rated as having a low degree of superhuman strength allowing him to lift 800 pounds. Peak Human Speed: Deadpool can run as fast as a trained athlete.
In Superman All Star when he was supercharged by being in direct contact with the sun, his limit was found to be 200 Quintillion tons, which would put Superman's maximum lift limit is 66.67 Quintillion tons when not under the effect, but he felt like he could do more, so that shows he's not actually straining himself ...
2) Captain Marvel
She holds her own with Thanos in hand-to-hand combat for longer than Thor, Iron Man, or Steve Rogers, and takes down his enormous warship single-handedly.
Thor. Thor, the god of Thunder, was undoubtedly the most powerful member of the original Avengers. His power continues to grow in the Marvel Cinematic Universe.
Determining the strongest Avenger in the MCU is tricky since each brings something unique to the table, and Thor and Hulk are the top contenders in terms of sheer physical strength. However, regarding versatility and range of abilities, Captain Marvel and Doctor Strange are formidable opponents.
Like his namesake, Spider-Man's strength and agility stand far above those of the average human, allowing him to lift nearly ten tons and to leap and move at incredible speeds with high accuracy. He also heals faster than normal when injured, though he is not completely immune to viruses and other human ailments.
According to several Marvel sources including The Marvel Encyclopedia, Spider-Man's maximum strength is being able to lift 10 tons.
Superhuman Strength: Thor possesses vast superhuman strength, the full limits of which aren't known. However, he is capable of lifting well in excess of 100 tons.
Thor: 3,500 lb.
Assessing Thor's strength might be even harder than the Hulk. Basing it off his pitches with the hammer Mjolnir won't help us either; the mystical mallet's weight is a mystery, and while we can't be sure, it seems to be psionically connected to him, flying where he wants.
It's estimated that Black Panther can lift up to 800 lbs which is around 363 kg, and is borderline superhuman but not quite. Despite this limit, Black Panther is known to wrestle with enemies far stronger than he is.
Thor can lift well over 100 tons with no difficulty, he is in the so-called Class-100 strength category.
The hammer Stormbreaker is very similar to Mjolnir, made of mystic Uru metal and is nearly indestructible. Worthiness: Just like the original Mjolnir, no one can lift Stormbreaker who is not worthy.
As Bruce Banner, the character is about 5 ft 9 in (1.75 m) tall and weighs 128 lbs (58.05 kg), but when transformed into the Hulk, the character stands between 7 and 8 ft (2.13 - 2.43 m) tall and weighs between 1,040 and 1,400 lbs (471.73 - 635.02 kg).
Superman has replaced the giant key with a normal-sized key which is made from super-dense dwarf star material and weighs half a million tons, restricting its use to those with immense superhuman strength. It has a team of robots working on various projects.
