Colossus' incredible strength class is 100+, which means he can consistently lift above 100 tons.
“Hulk is the strongest there is” is always a safe rule to follow. Hulk and Thor are probably of similar strength “at rest,” and Captain Marvel might be able to charge up her lifting ability to that level (though she's usually more of a “flying blaster” type), but Hulk's entire “thing” is strength.
Her battle cry, “Embiggen!,” refers to her ability to grow big and tall, and when she becomes a giantess Ms. Marvel is able to lift up to 75 tons. Ms. Marvel eventually learns how to hone her powers to shrink and sneak.
Through these means Ben's strength has increased to much higher levels allowing him to now lift up to 100 tons and possibly even more. Ben's strength is such that he once stopped a multistory building that weighed roughly 30,000 tons from toppling and then pushed it back into place.
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 ...
According to his official Marvel page, Spider-Man is capable of lifting up to ten tons, and that means that he is a lot stronger than some of the other characters that have peak-human strength. However, Spider-Man's strength pales in comparison to the likes of Thor and the Hulk.
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.
Great Power. 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.
But what makes Captain Marvel so captivating is that she's all-around strong. She can endure a nuke and duke that energy out in turn; she's served at every level of the military from trainee to commander of the combined Earth defenses; she's quicker than the speed of sound, sharp as a tack, and can lift a hundred tons.
Superhuman Strength: Loki, without the aid of anything, through his own biology, possesses superhuman strength that is substantially superior to that of an average Asgardian male. He possesses sufficient physical strength to lift up to 50 tons.
The adamantium renders his bones virtually unbreakable and his claws capable of penetrating almost any substance depending on its thickness and the force he exerts. His reinforced skeleton also enables him to withstand heavy physical pressure, giving his muscles sufficient force to briefly lift 800 pounds or more.
Yes, even Spider-Man has been worthy of holding the hammer of Thor.
A spider can lift 170x their weight, and if Peter has inherited a spider's powers, he could lift about 25000 pounds, roughly translating to 12.5 ton. But in the comics it has been proven he can lift up to 100-300 tons if under extreme conditions.
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.
Superhuman Strength: Thor possesses class 100 strength and is easily capable of lifting 100 tons. Superhuman Durability: While in the form of an Asgardian Goddess, Thor possesses virtual invulnerability and immunity to all known Earthly diseases and infections.
While not superhuman, he is nearly as strong as a human being can become. He can lift (press) a maximum of 750 pounds with supreme effort. Abilities: An accomplished gymnast and acrobat, T'Challa is also an expert tracker. In addition, he has mastered various African martial arts.
Powers and abilities
He has the proportionate strength, speed, and agility of a spider. If his strength is equal to that of the original Spider-Man, he should be able to lift a maximum of approximately 10–15 tons and leap roughly 30 feet in the air.
Batman's Strength Is On A Nearly Superhuman Level
In Batman #655, Bruce is shown to be bench pressing over 1000 pounds during one of his regular workouts. In Batman Odyssey #2, Bruce mentions that his maximum leg press is 2500 pounds.
Thor can lift well over 100 tons with no difficulty, he is in the so-called Class-100 strength category. This means he is in the same strength category as the Hulk, but we have seen in Thor: Ragnarok that Thor can catapult the Hulk to the other side of the room with ease.
Strength Level: Venom possesses superhuman strength enabling him to lift (press) almost 11 tons. Known Superhuman Powers: The alien costume, which has grafted itself to the nervous system of Eddie Brock, somehow absorbed the powers of Spider-Man during its brief symbiotic relationship with him.
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.
KNOWN SUPER HUMAN POWERS: The Beast has the superhuman strength, agility, endurance, speed and dexterity. He is strong enough to lift (press) 2,000 pounds. His legs are powerful enough to enable him to leap 14 feet high in a standing high jump, and 22 feet in a standing broad jump.
As a result of the Goblin Formula, Norman possesses super human strength (able to lift nine tons), speed, reflexes, endurance, and healing. He can regenerate damaged tissue and organs (though not at the same rate as the mutant Wolverine).
Miles possesses similar spider-based abilities as Peter Parker; he has the proportionate strength, speed, stamina, durability, and reflexes of a spider. He can lift up to 10 tons, leap several stories, move much faster than the average human, and is generally more resistant to injury or fatigue than normal people.
