Adamantium

One of Wolverine’s abilities may also be a weakness, especially when faced with people who can control it. Magneto is one of them – and the powerful supervillain used it against him – but there are others, as well.

In Death of Wolverine, the mutant is left without his healing factor, which also makes it possible for adamantium to bond with his skeleton. The story’s villain, Doctor Abraham Cornelius, needs his healing factor for his experiments (creating other Weapon Xs). He moves forward without the healing factor, but Wolverine stops him in time, slashing the adamantium containers and putting a stop to the experiments.

He’s covered in the metal, and suffocates when it hardens. It is a pretty horrific way to die, if you ask us.

But these are comics – and Wolverine’s been resurrected as many times he’s been killed. Could this happen in the movies as well? We bet it could.
