His adamantium claws are one of the few weapons in the Marvel Universe that can consistently pierce Hulk's skin and Wolverine has no problem going for Hulk's head. In fact, if it came down to it, Wolverine could cut Hulk's head off, ending the Hulk once and for all.
Wolverine, given enough time, could defeat Colossus in a fight using only his claws, but he would have a terrifically difficult time doing so; the latter's skin is made of adamantium, same as Logan's claws, and even a demon-controlled Wolverine can do very little against him.
Despite his immense power, the Hulk has been defeated by heroes like Wolverine, Iron Man, Puck, and the Punisher. Spider-Man, Fantastic Four, and the Thing have also managed to take down the Hulk using their intelligence, teamwork, and unique abilities.
While Thor is easily the more powerful of the two, he finds himself incapable of matching Wolverine's speed and agility. The mutant is able to get in several swipes at the Asgardian - drawing blood - and even goes full leapfrog on him, impaling him through the back with all six adamantium claws.
Swords, knives, and more have been used against Hulk and almost none of them even leave a scratch or mark on him. However, with that said, there are two bladed weapons that can cut into Hulk's skin.
In that limited series (titled Ultimate Wolverine vs Hulk), the Hulk rips Wolverine in half. While epically gruesome, this scene caused some discord within the fandom, since many fans argued that Wolverine's adamantium skeleton should have prevented that from happening.
Ultimate Wolverine: Who Wins In A Fight? On top of that, Logan's claws can cut through nearly anything, including the skin of beings like the Hulk. Piercing Superman's flesh would be difficult but far from impossible for Wolverine, making the Man of Tomorrow vulnerable to every slash and stab attack Logan lands on him.
Mjolnir also has the advantage of being enhanced by magic and holds the power of a cosmic storm within it. In the case of Thor's Mjolnir versus Wolverine's adamantium claws, Thor's hammer has a clear edge.
Magneto can manipulate adamantium. Magneto has always been able to affect adamantium. This happens in many of different stories, including when Magneto slowly pulls Wolverine's adamantium-coated skeleton straight out of his body.
This Hulk even ripped Wolverine in half in one comic book storyline. The Planet Hulk and World-Breaker Hulk storylines saw the Jade Giant almost completely obliterating all the Marvel heroes, even the Sentry. The Hulk is one character Deadpool can't beat.
Physically they're pretty evenly matched, but Thanos is just a much more skilled fighter. No stones were used in the fight. Per Joe Russo: "I would say that he's just that powerful," said Joe Russo.
Hulk's inability to break Wolverine and his adamantium claws isn't an indictment of the green monster's strength but more shows how strong Wolverine's metal-coated bones really are.
Because without altering any continuities, if Fox's Wolverine and Marvel's Captain America were to come to blows, the claws would slice through the shield like a hot knife through butter. Vibranium can absorb kinetic energy, but it isn't indestructible (as evidenced by Thanos destroying the shield in Endgame).
Wolverine isn't just armed with enhanced senses and an impressive healing factor - his skeleton is also encased completely in adamantium. His claws are sheathed in the metal, allowing them to be razor-sharp and could certainly cut through Iron Man's armor.
Wolverine's vaunted claws can cut the Hulk's skin, but they can't do diddly-squat to the Juggernaut. Wolverine can't hurt the Juggernaut, but the Juggernaut sure as Hell can hurt Wolverine.
No it is NOT. If you are talking about True Adamantium (the metal that makes up Ultron and a few other characters) it is weaker than Uru. Thor has proven this when he went full strength on a small cylinder of it and “barely” dented it. Note that it was BARELY…but he did do it.
The general consensus was that Wolverine's claws could theoretically puncture Superman's skin, but that it would require tremendous super strength behind them to do so, which Wolverine doesn't have.
It was actually an instance of Thor destroying a version of Ultron made out of adamantium during the crossover, "Ultron Unlimited," that introduced the concept of secondary adamantium into the Marvel Universe (it had been theorized in handbooks before, but not yet in the actual comic books), as Iron Man notes that Thor ...
Wolverine's claws are nearly unbreakable and can slice through almost anything, but they are not strong enough to cut Superman, let alone Darkseid, they cannot be fired from and then reeled back into his body, and they don't contain an immensely powerful toxin strong enough to hurt beings that are basically gods.
As arguably the most powerful being in DC Comics, Superman would very likely be able to win over Wolverine. Firstly, his strength alone may be enough to bend adamantium, making it incredibly hard for Logan's body to heal properly.
Magneto rips the Adamantium from Wolverine's bones, killing Wolverine, leaving just a severely charred skeleton and an arm of flesh due to his healing factor not working.
Even if the fight happens with the stones, it'll very difficult for Thanos to kill Wolverine but eventually, Thanos will win given that he has the most powerful weapon in the world. But if the battle is between Thanos without the gauntlet and Wolverine, then Wolverine will definitely defeat him.
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.
