The one thing that can break through Luke's skin is adamantium, the world's hardest metal and the coating around Wolverine's bones and claws. Someone with an adamantium blade would be trouble for Cage, but it can also be his life saver. Luke Cage has extremely durable skin, but his insides are not.
Lasers. Adamantium isn't the only thing that can cut Luke Cage though, he once had to have surgery on his internal organs. To be able to perform the surgery, his skin was pierced by the use of high powered lasers. Now we're talking some serious lasers, lasers that can break titanium steel.
Along with his bulletproof skin, Luke Cage has strength and a healing factor, making the rest of his body more resilient than that of a normal human being. Just as it takes a big gun at point-blank range to do any damage, it would require either a corrosive acid or a very potent poison in order to harm Cage.
Luke Cage's main weaknesses are that 1) his internal organs aren't any more durable than a normal human's and 2) that he needs to breathe like the rest of us. If you can manage to penetrate his skin and muscle tissue, you can severely injure or kill Luke Cage.
It was only by heating up Cage's body at a high temperature that Claire Temple and Noah Burstein were able to remove all the shrapnel from Cage's body, saving his life, causing Cage's durability to increase, helping him to withstand Judas Bullets.
Luke Cage—immune to explosions, extreme temperatures, and electric shocks—also had the ability to recover from a rare injury three times faster than the average human. Plus, due to his formative years as a gang member, Luke's powerful hand-to-hand combat skills confirmed his status as a Super Hero.
Lucas gains enhanced strength and near-invulnerability from Burstein's experiment. Conventional bullets cannot pierce his skin, and a raging fire has no effect on him whatsoever. Receiving a punch from a normal human will result in more than a few broken bones for the person stupid enough to engage Cage.
If the star's weight was equivalent to the weight of Sol, the Hulk is capable of lifting 2 octillion tons. These numbers are far beyond human comprehension, and the laws of physics as humanity understands them simply do not apply to the Hulk; lifting a mountain is a trivial matter.
Due to Luke Cage's dense skin, he can withstand any kind of temperature, be it very hot or very cold. His body is immune to extreme temperatures and it has helped him go to places others wouldn't like to go to.
His strength was definitely superhuman, but it was nothing compared to the Hulk. The Hulk was far stronger than Cage even during his first appearances, and his capacity for great feats quickly ballooned.
The Hulk's skin is nearly impenetrable and his lung capacity allows for long periods of submersion in water, exposure to many forms of gases, and even to temporary survival in the airless vacuum of outer space.
Initially, it was only sufficient enough to lift approximately 5 tons. However, with extensive physical training and years of experience as a super hero, his strength was increased to approximately 25 tons and he is able to punch through barriers as thick as 4-inch steel plate.
Jesse has almost identical powers which was how he managed to put up a fight against Luke. On the other hand, Luke has unbreakable skin and strength comparable to, if not stronger than Jessica's.
Iron Fist also possesses healing abilities that allow him to recover from any injury or illness, as well as cure others. His spiritual training makes him able to sense mystical energy. At times, Danny Rand has even absorbed energy attacking him and used it to power himself.
Claire Temple and Luke Cage were walking in the park talking about Cage's past. Diamondback set up a sniper a ways away and shot a Judas Bullet at Cage. The bullet easily penetrated his skin and he fell to the ground much to the shock of Temple. Temple told Cage to breathe as he got carted off in an ambulance.
Diamondback (Willis Stryker) is a fictional character appearing in American comic books published by Marvel Comics. He is primarily an enemy of Luke Cage and is notable for being the first major supervillain that he faced.
And while Colossus is naturally strong, when he is in this armored form, he is impossibly strong with a class 100 strength, meaning that he could lift more than 100 tons.
He's super strong, like Jessica Jones and Danny Rand, but his defining physical trait is his impenetrable skin. You can't shoot Luke Cage — the bullets just bounce right off him. But Luke is certainly not unkillable.
