Hugh Jackman is nearing his final run as some things remained practically the same, such as the Ol' Canucklehead's healing factor.

He's survived gunshots to the head, vaporization from the Dark Phoenix, countless battles with Magneto, as well as cerebral time-travel, yet he always comes out on top -- and damn near everything the world as thrown at him, what are his weaknesses?

Here are 15 Weaknesses You Didn't Know Wolverine Had.

15. Overloading his senses (e.g. Hulk's Thunderclap)

Wolverine may not have as angry of a personality as the Hulk, but he's certainly not somebody one would associate the word "zen" with either. That's what makes him and the Hulk compatible to be friends. Still, when it comes to comic books, as seen by two of 2016's biggest movies (Captain America: Civil War), even friends fight occasionally.

Over the years, tears Wolverine in half.

However, if they ever find themselves in a fight, one of the best ways for Hulk to weaken Wolverine, albeit temporarily, is to overwhelm the Ol' Canucklehead's senses by using his Thunderclap. By slapping his hands together with all his might in front of Wolverine in The Incredible Hulk #340, Hulk almost kills the mutant by overwhelming his acute hearing senses.

14. Muramasa blade

Guns. Swords. Arrows. There aren't many things in the world that can weaken Wolverine for longer than a few minutes. Conventional weapons can hurt him, as we've seen countless times in both the comics and the movies, but they cannot disrupt his ability to heal. However, there is one weapon that can: the Muramasa Blade.

The legendary Japanese swordsmith, Muramasa, constructed many blades during his time, but two of them were among his most lethal, and that's because they were imbued with pieces of either his or someone else's soul. The seemingly immortal swordsman constructed the first blade for himself, known as the Black Blade. Then, centuries later, he constructed another blade for Wolverine after his wife, Itsu, had been murdered by the Winter Soldier.

This blade, forged out of the Muramasa Sword, contained a piece of Logan's soul. Its immense power doesn't just apply to Wolverine's enemies, but to himself as well. He once said to Captain America that the Muramasa Blade is "the only thing in the world that can put me down for good."

13. Drowning

When it comes to someone like Wolverine, his healing factor allows him to bounce back from just about anything. That doesn't mean ordinary perils escape him, though. Simple things like drowning can harm him enough to disable him. The question is, can drowning kill him? Yes and no. One of the many beauties of Wolvie's healing factors is that it can also repair organs, which extends to the brain. That means, despite suffering from hypoxemia, Logan's brain stands a chance to repair itself.

Though it would be foolish to use the X-Men: Days of Future Past. However, he didn't stay dead, for when Mystique, posing as Col. Stryker, pulled him out of the water, he started breathing again. Yet, in the comics, Wolverine is more than capable of dying from drowning. In fact, in Wolverine: Weapon X #5, he says that he considers drowning to be the worst way to die.

12. Anti-metal

Other than his rapid, seemingly unparalleled healing factor, Wolverine is known for his metal claws. During his time with the Captain America's shield is made of. Without some form of magic or extraterrestrial weapon, both alloys are virtually impossible to destroy. That's why Cap's shield always protects him, and that's why Wolvie's claws never break.

However, there is one thing that can penetrate Adamantium: Anti-Metal. Also known as the Antarctic variety, Anti-Metal is a Adamantium-coated bones to dissolve. Or, if someone simply poured Anti-Metal down Logan's throat, he would literally break apart from the inside out.

11. Adamantium poisoning

For several years, there was a lot we didn't know about Wolverine and how his mutant powers worked, or where his metal claws came from. In the '90s, Magneto once removed the Adamantium from Wolverine's system, thus revealing for the first time that Logan's claws were actually bone; his skeleton was merely coated with Adamantium.

The reason the process only worked with Logan, at the time, is because his healing factor prevented the Adamantium transfusion from killing him. In X-Men Vol. 2 #191, Serafina claims that there are 13 Adamantium allotropes -- "unstable, and short-lived, but virulently poisonous." She demonstrates their effects by attaching a device to Wolverine's claws, which gives him a taste of Adamantium nine, thereby incapacitating him.

Since Logan's healing factor kept the metal's poison at bay, when Magneto removed all of it from his body, his powers increased exponentially, furthering him into a more animalistic state. As it turns out, what made his bones and claws indestructible was actually what was hindering him from reaching his full potential.

10. Carbonadium

In addition to Vibranium and Adamantium, which are the strongest metal alloys in the Marvel Universe, there is Carbonadium -- arguably the third strongest alloy. It's stronger than steel, as well as cheaper and more malleable than Adamantium, but it isn't as strong nor as indestructible as Adamantium. The alloy first appeared in X-Men Vol 2. #4 in the early '90s as a creation of the Soviet Union, which became synonymous with the X-Men villain Arkady Rossovich, aka Omega Red.

When it comes to building weapons, Carbonadium may not be the first thing people think of when considering levels of durability. However, the one thing Carbonadium has going for it is that it's highly radioactive, and can, therefore, slow the accelerated healing abilities of mutants. That makes Carbonadium weapons, created with a Carbonadium Synthesizer, hazardous to Wolverine. For instance, the Merc With a Mouth decapitated Wolverine using a Carbonadium-laced sword, in Deadpool Kills the Marvel Universe #3. Speaking of which...

9. Decapitation

Can Wolverine die? That is a question that has plagued casual comic book readers and moviegoers for years. Thanks to 20th Century Fox's X-Men franchise, it appears that the Ol' Canucklehead can survive virtually anything, even an Adamantium bullet to the head. And the comics aren't much help on that front, either. Logan once bested starvation by eating his own limbs, only to have them grow back, thus endowing him with an endless supply of sustenance. But the fact is, Wolverine can definitely die, and Deadpool using a Carbonadium-laced sword to decapitate him is just one of the ways in which that can happen.

For anyone, including immortals, decapitation usually does the trick, even if their accelerated healing abilities permits them to survive everything else. According to the Xavier Protocols, a set of plans revealing the X-Men's weaknesses, the best way to kill Wolverine would be to decapitate him, for attacking him head-on would be suicide. The protocols state, specifically, that "his head would have to be severed, and removed utterly from the vicinity of his body to prevent swift flesh and nerve regrowth." It's not enough to decapitate him; Logan's head would need to remain far away from his body.

8. Love

Love conquers all, as the old adage goes. To most characters, it remains just that, a phrase. But to Logan, sometimes he takes that phrase to heart. The fact is, James Howlett has lived a very long life, so it only makes sense that he's also had several relationships, many of which didn't end well.

Fans of the X-Men movies know that Logan has a soft spot for his fellow X-Men member, from pursuing her. He knew what he wanted, and that was the problem. She became a weakness for him; we see that unfold in the movies, but it also happened, from time to time, in the comics.

Some comic book readers consider Jean Grey to be the love of Logan's life, but she wasn't the only person he was smitten with. Wolverine has dated dozens of women over the years; he married some of them and even had kids! However, in the end, most of the women in his life end up leaving him or dying. He's just not the sort of character that's destined for a happy ending.

7. De-aging (or aging in general)

Beyond his traditional weaknesses, there are a wide variety of things that can befall Wolverine which would force his accelerated healing abilities to actually kill him, and one of those things is de-aging. Most people would presumably welcome de-aging if it meant they could live a little while longer, but not Logan. If he were to de-age, he wouldn't live longer; he would die.

In Wolverine: Killing Made Simple, there is an extended scene in which Wolverine explains all the various ways he could die, and de-aging, though coveted by the rest of the world, would result in one of the most brutal deaths for Wolvie. As we know, Logan was born with bone claws that were coated with Adamantium later in life. So, if he were to de-age to say 13 years-old, the Adamantium would still be there.

In the comic, he says his metal bones wouldn't de-age; "it'll burst through my skin, dislodge my organs, and even if I live through that... then I'll start to heal. My skin will grow apart from my bones, maybe through them. My brain will be too small; it'll roll around in my skull." He would die from the inside out.

6. Intense heat (like tossing him into the sun)

As seen in The Wolverine, as well as in a few comic story arcs, Wolverine has survived a nuclear blast or two in his day. If he could do that, then you might think he could presumably survive anything, but that's not the case. In the comic Wolverine: Killing Made Simple, Logan its that tossing him into the sun would likely kill him. After all, Magneto once attempted to do just that in the Planet X story arc from the early '00s, when he sent Asteroid M hurtling toward the sun with Wolverine and Jean Grey aboard.

Although Logan ended up killing Jean so she could resurrect as the Phoenix and bring them back to safety, he said he could feel his flesh boiling off. According to him, there's no way he could survive that. But the thing is, we've seen him survive countless other similar attacks, so while he wouldn't survive being tossed into the sun, he should be able to survive something with the power of the sun (like a nuclear blast). It just would take him a long time to heal.
