It is possible for an opponent with sufficient physical or mystical strength of their own to turn the Juggernaut's unstoppable movement against him, by redirecting his motion so that he gets stranded in a position in which he has no escape; both the Hulk and his son, Skaar, have done this physically, and Thor has done ...
The Juggernaut, despite his incredible strength, has been defeated by surprising heroes like Professor Xavier, Cyclops, Banshee, and Lost. These heroes used their unique abilities, whether it be telepathy, strategic thinking, sonic blasts, or reality manipulation, to overcome the seemingly unstoppable villain.
Despite the fact that no physical challenge is enough to stop the Juggernaut, and telepathic attacks only prove to temporarily slow him down, it seems he does have a weakness after all, as X-Men confirms a brain aneurysm is the one thing that can actually kill the Juggernaut.
The Juggernaut got his skull caved in during the 2023 Hellfire Gala, when Nimrod and the rest of Orchis stormed the event and slaughtered everyone in sight.
The Juggernaut's strength comes from the Crimson Gem, making him vulnerable to having it removed and losing his power. In X-Men #27, Dr. Stasis plans to cut the Crimson Gem out of Juggernaut's body, potentially de-powering him.
Since Mjölnir can only be wielded by the worthy, Juggernaut has no chance of lifting it. However, that doesn't stop him from using it. In most fights against Thor, Thor throws his hammer at full speed towards Juggernaut, but Juggernaut's mystical force field stops Mjölnir in mid-air.
The only character to have stopped Juggernaut while he was in motion as an act of pure physical strength was the Hulk while he was War, a horseman of Apocalypse and empowered with Celestial technology. When Marko gains complete access to the Gem's powers during the Trion saga, it increases his power a thousandfold.
This feat means that even though Juggernaut's magic makes him unstoppable, Hulk has the overwhelming power to thwart Juggernaut's supernatural rules. But he still can't force him to surrender, or destroy him as he would need to for a true 'win.
Juggernaut has also defeated the Hulk on more than one occasion, so putting his strength level at well over a hundred tons wouldn't be a stretch. Somehow, Nimrod was more powerful than that, and could knock out Juggernaut in a few hits.
Despite the fact that Galactus is a cosmic being older than the universe who regularly consumes entire planets, the earthbound Juggernaut shockingly proves to be more powerful than him–and one stunning side-by-side comparison confirms it.
While Deadpool 2's Juggernaut was doubtlessly powerful, the original version is an unstoppable force of nature. In Uncanny X-Men #183, Juggernaut destroyed Colossus (and the bar they were in) yet again, and even when both combatants were magically amped in Fear Itself Colossus never got a clear victory.
Juggernaut's power is unlimited, especially when sponsored by Cyttorak. And with his willingness to win any fight, he could even manipulate Colossus, though he's never been shown to be that clever. Juggernaut would really only need to land a single hit on Colossus to knock him out and make him lose him armored form.
Fortunately, as long as he has Mjolnir, he won't need to. When the two faced each other in the past, Thor beat Juggernaut by generating an anti-magic whirlwind with his hammer, effectively removing Cain's magical invulnerability.
Juggernaut and the X-Men have had some fierce battles, and while Wolverine has played a key role in beating the Juggernaut — usually using his claws to remove Juggernaut's helmet for the X-Men's telepaths can take him down — he has never defeated Juggernaut on his own.
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.
Soon, though, they began to fight each other and the Hulk easily tore his helmet off. He was about to attack the Hulk again, but then the X-Men luckily showed up and Professor X used his powers to knock the helmet-less Juggernaut out.
“The Incredible Hulk” only grossed $264 million worldwide, a sharp decline from “Iron Man's” $585 million. It's well known by now that Marvel scrapped all the follow-up plans it had for Norton continuing as Hulk. He was later replaced by Mark Ruffalo.
There's been confusion among fans about whether or not Loki is worthy of wielding Thor's hammer, but Marvel has finally confirmed that the God of Mischief can indeed lift Mjolnir. The Immortal Thor #4 complicated the issue of Loki's worthiness by not allowing him to solely be the one to lift Mjolnir.
You must be worthy. Hulk is not, has not, and likely will not, ever be worthy. (Although, to be fair, writers have just been giving the hammer to characters willy nilly lately, so maybe he actually will be worthy or rather, simply lift it, in the near future.
Colossus' ability to wield Mjolnir shows that he is pure of heart and ultimately good, despite recent actions calling into question his integrity. Colossus' heroic nature is evident in his willingness to sacrifice himself for others, as seen in the Legacy Virus storyline.
