WOLVERINE'S ADAMANTIUM SKELETON!! This is pretty much the greatest invention EVER!!
Adamantium is a virtually indestructible man-made steel alloy which does not occur in nature and whose exact chemical composition is a United States government classified secret. Adamantium is not an element: its properties do not qualify it for any know space on the Periodic Table of Elements. Rather, Adamantium is a series of closely related compounds of iron created through a secret process discovered by the American metallurgist Dr. Myron MacLain.
True Adamantium is nearly as strong as Captain America's shield, and is, for all practical purpose, indestructible. The degree of impermeability varies directly with the thickness of the Adamantium. A direct blow from Thor's hammer, conveyed with the thunder god's full strength, will slightly dent a solid cylinder of True Adamantium. A sufficient mass of Adamantium could survive a direct hit from a nuclear weapon.
Wolverine possesses artificial claws made of True Adamantium and his bones have been fused with Adamantium in an unexplained manner so as to greatly increase their tensile strength.
